+
+Write a handoff summary of the current conversation so a fresh agent can continue the work. Instead of saving it, launch a background agent seeded with the summary as its prompt: `claude --bg --name "<descriptive name>" "<handoff summary>"`. It starts in the current working directory and returns immediately; the user manages it with `claude agents`.
+
+Always pass `-n`/`--name` with a descriptive name (e.g. `--name "Fix login bug"`) — it sets the display name shown in the job list, session picker, and terminal title.
+
+Include a "suggested skills" section in the summary, which suggests skills that the agent should invoke.
+
+Do not duplicate content already captured in other artifacts (PRDs, plans, ADRs, issues, commits, diffs). Reference them by path or URL instead.
+
+Redact any sensitive information, such as API keys, passwords, or personally identifiable information — the summary becomes the agent's prompt.
+
+If the user passed arguments, treat them as a description of what the next session will focus on and tailor the summary accordingly.

+description: Graduate a completed feature from .scratch/<slug>/ into the permanent docs/ structure. Run when all issues in the feature are done, or when the agent notices a feature looks complete. Always confirm with the user before moving files.
+---
+
+# Close Feature
+
+Merge a completed `.scratch/<slug>/` feature into the permanent `docs/` structure and delete the scratch directory.
+
+## When to run
+
+Run this skill when:
+- The user explicitly calls `/close-feature <slug>`
+- You notice during any task that ALL issues in a `.scratch/<slug>/issues/` directory have `Status: done` — surface this proactively and offer to close ("It looks like <slug> is fully done. Want me to graduate it to docs/?")
+
+Always confirm before moving any files.
+
+## Process
+
+### 1. Identify the slug
+
+If called with an argument (`/close-feature <slug>`), use that. Otherwise list all `.scratch/` directories and ask the user which one to close.
+
+### 2. Verify all issues are done
+
+Read every file in `.scratch/<slug>/issues/`. Check for a `Status:` line.
+
+If any issue does NOT have `Status: done`, list the incomplete ones and stop — ask the user whether to mark them wontfix or wait.
+
+### 3. Show the user what will move
+
+Present a summary:
+- N issues → `docs/issues/` (renumbered from next available)
+- PRD.md → `docs/PRD.md` (or merged if one already exists)
+- prd.json → `docs/prd.json` (merged into existing user stories array)
+- Any ADRs written during the feature → `docs/adr/` (renumbered from next available)
+- `.scratch/<slug>/` deleted
+
+Ask: "Proceed?" before touching anything.
+
+### 4. Move issues
+
+Find the highest existing number in `docs/issues/`. Issues from `.scratch/<slug>/issues/` take the next slots in dependency order (lowest numbered first).
+
+Use `git mv` for each file so history is preserved:
+```
+git mv .scratch/<slug>/issues/01-foo.md docs/issues/<next>-foo.md
+```
+
+### 5. Merge PRD
+
+If `docs/PRD.md` does not exist: `git mv .scratch/<slug>/PRD.md docs/PRD.md`
+
+If `docs/PRD.md` already exists: append the feature's Problem Statement and Solution sections under a `## <Feature Name>` heading. Do not overwrite the existing file.
+
+### 6. Merge prd.json
+
+If `docs/prd.json` does not exist: `git mv .scratch/<slug>/prd.json docs/prd.json`
+
+If `docs/prd.json` already exists: merge the `userStories` array from the scratch prd.json into the main one, assigning new sequential ids to avoid collisions. Update all merged stories to `"status": "done"`.
+
+### 7. Move ADRs
+
+If any `.md` files exist directly in `.scratch/<slug>/` (not in `issues/`) that look like ADRs (contain `## Status` and `## Decision`), move them to `docs/adr/` renumbered from the next available slot.
+
+### 8. Delete scratch directory
+
+```
+git rm -r .scratch/<slug>/
+```
+
+If `.scratch/` is now empty, remove it too (it has no meaning without sub-features).
+
+### 9. Commit
+
+```
+git add docs/
+git commit -m "docs: close feature <slug> — graduate to docs/"
+```
+
+### 10. Update ralph default (if needed)
+
+If `scripts/ralph_progress.py` exists and its `DEFAULT_PRD` still points at `.scratch/<slug>/prd.json`, update it to `docs/prd.json`.
+
+## Machine setup reference
+
+Skills are stored in `.agents/skills/` and symlinked into `.claude/skills/`. Both directories are git-tracked so cloning the repo gives you all skills automatically.
+
+**On a new machine (Linux/Mac):**
+```bash
+git clone <repo>
+# Skills work immediately — .claude/skills/ symlinks resolve automatically.
+# .claude/settings.local.json is machine-local (gitignored).
+# Recreate it if you need custom permission allowlists.
+```
+
+**On Windows:**
+```bash
+git clone -c core.symlinks=true <repo>
+# Requires Developer Mode or admin rights for symlink creation.
+# If symlinks didn't resolve, run: scripts/link-skills.sh (or re-run /setup-matt-pocock-skills)
+```
+
+**Codex:** reads `AGENTS.md` at the repo root — already tracked, no setup needed.

+description: Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to "review since X".
+---
+
+Two-axis review of the diff between `HEAD` and a fixed point the user supplies:
+
+- **Standards** — does the code conform to this repo's documented coding standards?
+- **Spec** — does the code faithfully implement the originating issue / PRD / spec?
+
+Both axes run as **parallel sub-agents** so they don't pollute each other's context, then this skill aggregates their findings.
+
+The issue tracker should have been provided to you — run `/setup-matt-pocock-skills` if `docs/agents/issue-tracker.md` is missing.
+
+## Process
+
+### 1. Pin the fixed point
+
+Whatever the user said is the fixed point — a commit SHA, branch name, tag, `main`, `HEAD~5`, etc. If they didn't specify one, ask for it.
+
+Capture the diff command once: `git diff <fixed-point>...HEAD` (three-dot, so the comparison is against the merge-base). Also note the list of commits via `git log <fixed-point>..HEAD --oneline`.
+
+Before going further, confirm the fixed point resolves (`git rev-parse <fixed-point>`) and the diff is non-empty. A bad ref or empty diff should fail here — not inside two parallel sub-agents.
+
+### 2. Identify the spec source
+
+Look for the originating spec, in this order:
+
+1. Issue references in the commit messages (`#123`, `Closes #45`, GitLab `!67`, etc.) — fetch via the workflow in `docs/agents/issue-tracker.md`.
+2. A path the user passed as an argument.
+3. A PRD/spec file under `docs/`, `specs/`, or `.scratch/` matching the branch name or feature.
+4. If nothing is found, ask the user where the spec is. If they say there isn't one, the **Spec** sub-agent will skip and report "no spec available".
+
+### 3. Identify the standards sources
+
+Anything in the repo that documents how code should be written, such as `CODING_STANDARDS.md` or `CONTRIBUTING.md`.
+
+On top of whatever the repo documents, the Standards axis always carries the **smell baseline** below — a fixed set of Fowler code smells (_Refactoring_, ch.3) that applies even when a repo documents nothing. Two rules bind it:
+
+- **The repo overrides.** A documented repo standard always wins; where it endorses something the baseline would flag, suppress the smell.
+- **Always a judgement call.** Each smell is a labelled heuristic ("possible Feature Envy"), never a hard violation — and, like any standard here, skip anything tooling already enforces.
+
+Each smell reads *what it is* → *how to fix*; match it against the diff:
+
+- **Mysterious Name** — a function, variable, or type whose name doesn't reveal what it does or holds. → rename it; if no honest name comes, the design's murky.
+- **Duplicated Code** — the same logic shape appears in more than one hunk or file in the change. → extract the shared shape, call it from both.
+- **Feature Envy** — a method that reaches into another object's data more than its own. → move the method onto the data it envies.
+- **Data Clumps** — the same few fields or params keep travelling together (a type wanting to be born). → bundle them into one type, pass that.
+- **Primitive Obsession** — a primitive or string standing in for a domain concept that deserves its own type. → give the concept its own small type.
+- **Repeated Switches** — the same `switch`/`if`-cascade on the same type recurs across the change. → replace with polymorphism, or one map both sites share.
+- **Shotgun Surgery** — one logical change forces scattered edits across many files in the diff. → gather what changes together into one module.
+- **Divergent Change** — one file or module is edited for several unrelated reasons. → split so each module changes for one reason.
+- **Speculative Generality** — abstraction, parameters, or hooks added for needs the spec doesn't have. → delete it; inline back until a real need shows.
+- **Message Chains** — long `a.b().c().d()` navigation the caller shouldn't depend on. → hide the walk behind one method on the first object.
+- **Middle Man** — a class or function that mostly just delegates onward. → cut it, call the real target direct.
+- **Refused Bequest** — a subclass or implementer that ignores or overrides most of what it inherits. → drop the inheritance, use composition.
+
+### 4. Spawn both sub-agents in parallel
+
+Send a single message with two `Agent` tool calls. Use the `general-purpose` subagent for both.
+
+**Standards sub-agent prompt** — include:
+
+- The full diff command and commit list.
+- The list of standards-source files you found in step 3, **plus the smell baseline from step 3** pasted in full — the sub-agent has no other access to it.
+- The brief: "Report — per file/hunk where relevant — (a) every place the diff violates a documented standard: cite the standard (file + the rule); and (b) any baseline smell you spot: name it and quote the hunk. Distinguish hard violations from judgement calls — documented-standard breaches can be hard, but baseline smells are always judgement calls, and a documented repo standard overrides the baseline. Skip anything tooling enforces. Under 400 words."
+
+**Spec sub-agent prompt** — include:
+
+- The diff command and commit list.
+- The path or fetched contents of the spec.
+- The brief: "Report: (a) requirements the spec asked for that are missing or partial; (b) behaviour in the diff that wasn't asked for (scope creep); (c) requirements that look implemented but where the implementation looks wrong. Quote the spec line for each finding. Under 400 words."
+
+If the spec is missing, skip the Spec sub-agent and note this in the final report.
+
+### 5. Aggregate
+
+Present the two reports under `## Standards` and `## Spec` headings, verbatim or lightly cleaned. Do **not** merge or rerank findings — the two axes are deliberately separate (see _Why two axes_).
+
+End with a one-line summary: total findings per axis, and the worst issue _within each axis_ (if any). Don't pick a single winner across axes — that's the reranking the separation exists to prevent.
+
+## Why two axes
+
+A change can pass one axis and fail the other:
+
+- Code that follows every standard but implements the wrong thing → **Standards pass, Spec fail.**
+- Code that does exactly what the issue asked but breaks the project's conventions → **Spec pass, Standards fail.**
+
+Reporting them separately stops one axis from masking the other.

+name: wayfinder
+description: Plan a huge chunk of work — more than one agent session can hold — as a shared map of investigation tickets on your issue tracker, and resolve them one at a time until the way to the goal is clear.
+---
+
+A loose idea has arrived — too big for one agent session, and wrapped in fog: the route from here to a plan isn't visible yet. This skill charts it as a **shared map** on the repo's issue tracker, then works its tickets one at a time. The map is domain-agnostic — engineering work, course content, whatever fits the shape.
+
+## Refer by name
+
+Every map and ticket is an issue, so it has a **name** — its title. In everything the human reads — narration, the map's Decisions-so-far — refer to it by that name, never by a bare id, number, or slug. A wall of `#42, #43, #44` is illegible; names read at a glance. The id and URL don't vanish — a name wraps its link — but they ride *inside* the name, never stand in for it.
+
+## The Map
+
+The map is a single issue on this repo's issue tracker, labelled `wayfinder:map` — the canonical artifact. Its tickets are child issues of the map.
+
+The map is an **index**, not a store. It lists the decisions made and points at the tickets that hold their detail; a decision lives in exactly one place — its ticket — so the map never restates it, only gists it and links.
+
+**Where the map, its child tickets, blocking, and frontier queries physically live is tracker-specific.** Consult `docs/agents/issue-tracker.md` (the "Wayfinding operations" section) for how _this_ repo expresses them. If that doc is absent, default to the local-markdown tracker.
+
+### The map body
+
+The whole map at low resolution, loaded once per session. Open tickets are **not** listed — they are open child issues, found by query.
+
+```markdown
+## Notes
+
+<domain; skills every session should consult; standing preferences for this effort>
+
+## Decisions so far
+
+<!-- the index — one line per closed ticket: enough to judge relevance, then zoom the link for the detail the ticket holds -->
+
+- [<closed ticket title>](link) — <one-line gist of the answer>
+
+## Fog
+
+<!-- see "Fog of war" for what belongs here -->
+```
+
+### Tickets
+
+Each ticket is a **child issue** of the map; the tracker's issue id is its identity. Its body is the question, sized to one 100K token agent session:
+
+```markdown
+## Question
+
+<the decision or investigation this ticket resolves>
+```
+
+Each ticket carries a `wayfinder:<type>` label — one of `research`, `prototype`, `grilling`, `task` (see [Ticket Types](#ticket-types)).
+
+A session **claims** a ticket by assigning it to the dev driving the map, **first**, before any work, so concurrent sessions skip it. That assignee _is_ the claim: an open, unassigned ticket is unclaimed.
+
+Blocking uses the tracker's **native** dependency relationship — essential because it renders the frontier _visually_ in the tracker's own UI, so the human sees what's takeable without opening the map. Only a tracker that lacks native blocking falls back to a body convention. A ticket is **unblocked** when every ticket blocking it is closed; the **frontier** is the open, unblocked, unclaimed children — the edge of the known.
+
+The answer isn't part of the body — it's recorded on resolution (see [Work through the map](#work-through-the-map)). Assets created while resolving a ticket are linked from the issue, not pasted in.
+
+## Ticket Types
+
+- **Research**: Reading documentation, third-party APIs, or local resources like knowledge bases. Creates a markdown summary as a linked asset. Use when knowledge outside the current working directory is required.
+- **Prototype**: Raise the fidelity of the discussion by making a cheap, rough, concrete artifact to react to — an outline, a rough take, a stub, or UI/logic code via the /prototype skill. Links the prototype as an asset. Use when "how should it look" or "how should it behave" is the key question.
+- **Grilling**: Conversation with the agent. Uses the /grilling and /domain-modeling skills. Asks one question at a time. The default case.
+- **Task**: Literal manual work that must be done before the discussion can move forward — nothing to decide, prototype, or research. Moving data, signing up for a service, provisioning access. The agent automates it where it can; otherwise it hands the human a precise checklist. Resolved when the work is done; the answer records what was done and any resulting facts (credentials location, new URLs, row counts) later tickets depend on.
+
+## Fog of war
+
+The map is _deliberately_ incomplete: don't chart what you can't yet see. Beyond the tickets lies fog — the dim view of decisions and investigations you can tell are coming but can't yet pin down, because they hang on questions still open. Resolving a ticket clears the fog ahead of it, graduating whatever's now specifiable into fresh tickets — one at a time, until the way to the goal is clear and no tickets remain.
+
+The map's **Fog** section is where that dim view is written down: the suspected question, the area to revisit later, the risk you're deferring. Write as loosely or as fully as the view allows; it doubles as a signpost for collaborators reading where the effort is headed.
+
+**Fog or ticket?** The test is whether you can state the question precisely now — _not_ whether you can answer it now.
+
+- **Ticket when** the question is already sharp — even if it's blocked and you can't act on it yet.
+- **Fog when** you can't yet phrase it that sharply. Don't pre-slice fog into ticket-sized pieces: it's coarser than a ticket, and one patch may graduate into several tickets, or none, once the frontier reaches it.
+
+Fog excludes only what's already decided (that's Decisions so far) and what's already a ticket.
+
+## Invocation
+
+Two modes. Either way, **never resolve more than one ticket per session.**
+
+### Chart the map
+
+User invokes with a loose idea.
+
+1. Run a `/grilling` and `/domain-modeling` session to surface the open decisions.
+2. **Create the map** (label `wayfinder:map`): Notes filled in, Decisions-so-far empty, Fog sketched.
+3. **Create the tickets you can specify now** as child issues of the map — then wire blocking edges in a **second pass** (issues need ids before they can reference each other). Wiring sorts them into the frontier and the blocked; everything you can't yet specify stays in the Fog.
+4. Stop — charting the map is one session's work; do not also resolve tickets.
+
+### Work through the map
+
+User invokes with a map (URL or number). A ticket is **optional** — without one, you pick the next decision, not the user.
+
+1. Load the **map** — the low-res view, not every ticket body.
+2. Choose the ticket. If the user named one, use it. Otherwise take the first frontier ticket in order. **Claim it**: assign it to yourself before any work.
+3. Resolve it — **zoom as needed**: fetch the full body of any related or closed ticket on demand; invoke the skills the `## Notes` block names. If in doubt, use `/grilling` and `/domain-modeling`.
+4. Record the resolution: post the answer as a **resolution comment**, **close** the issue, and **append a context pointer** to the map's Decisions-so-far.
+5. Add newly-surfaced tickets (create-then-wire); graduate any fog the answer has made specifiable, clearing each graduated patch from the Fog so it lives only as its new ticket. If the decision invalidates other parts of the map, update or delete those tickets.
+
+The user may run unblocked tickets in parallel, so expect other sessions to be editing the tracker concurrently.

+description: Generate an interactive bash wizard that walks a human through a manual procedure — third-party setup, a one-off migration, an A→B state transition — opening URLs, capturing values, confirming each step, and writing .env files and GitHub Actions secrets.
+disable-model-invocation: true
+---
+
+# Wizard
+
+A **wizard** is a bash script that walks a human, step by step, through a manual procedure that's tedious to do by hand and tedious to re-explain to an AI every time. It opens each URL, says exactly what to click and copy, captures the values, writes them where they belong (`.env`, GitHub secrets), confirms at every stage, and shows how much is left. It might configure third-party services, run a one-off migration, or move the project from one state to another.
+
+The delightful UX is already solved by [template.sh](template.sh) — progress with time-remaining, confirmation gates, cross-platform URL opening (including WSL), hidden secret entry, idempotent `.env` upserts, `gh secret`/`gh variable` writes, and a closing summary. **Your job is only to scope the procedure and author its stages.** The library above the `STAGES` marker is identical in every wizard; that consistency is the point — never hand-edit it.
+
+A wizard is ephemeral by default — built for one run, saved to a scratch or `scripts/` path, deleted when the job's done. Commit it only when the user wants a repeatable setup path that should live in the repo.
+
+## Process
+
+### 1. Scope the procedure
+
+Work out every manual step the human must take and every value that gets captured along the way. Read the repo first — don't ask cold:
+
+- For setup: `.env`, `.env.example`, `.env.*`, `README`, `docker-compose*`, framework config, and `.github/workflows/*` (every `secrets.*` / `vars.*` reference is a value the wizard must produce).
+- For a migration or transition: the current state, the target state, and the irreversible actions between them.
+
+Then show the user the ordered list of stages and the values each produces, and confirm — they may add, drop, or reorder.
+
+**Done when:** every stage is named in order, and for each captured value you know (a) where the human gets it, (b) where it's written (`.env`, a GitHub secret, both, or nowhere — some stages are pure actions), and (c) whether it's secret (hidden entry) or public.
+
+### 2. Map each stage's journey
+
+For each stage, write the precise path a human follows: which URL to open, what to do there, where a value is shown, which variable it fills — e.g. "Dashboard → Developers → API keys → Reveal test key → copy". Where you don't actually know the current UI or the exact command, say so and ask the user or check the docs — never invent steps that may not exist.
+
+**Done when:** every stage traces to concrete instructions a stranger could follow.
+
+### 3. Author the wizard
+
+Copy `template.sh` to the target path. Replace the example stage with one `stage` per step, in dependency order. Use the library helpers — `stage`, `say`/`step`, `open_url`, `ask`/`ask_secret`, `write_env`, `set_secret`/`set_var`, `pause`/`confirm` — and set `TOTAL_STAGES` and `TOTAL_MINUTES` to honest estimates (this drives the time-remaining display).
+
+Hold the bar the template sets: open the URL before asking for its value, use `ask_secret` for anything secret, `write_env` every persisted value, `set_secret` only the values CI actually needs, and `confirm` before any irreversible action. Each `stage` clears the screen so only the current step is visible — keep a stage to one focused task so nothing the human needs scrolls away. Don't touch the library above the marker.
+
+### 4. Verify and hand off
+
+- `bash -n <script>`; run `shellcheck` if available.
+- `chmod +x <script>`.
+- Don't run it end-to-end yourself — it opens browsers and blocks on human input. Trace it statically instead: every value from step 1 is captured and lands where step 1 said, and every `set_secret` name exactly matches a `secrets.*` reference in CI.
+- Tell the user how to run it. If it's a repeatable setup path, commit it and link it from the README so the next person runs the script instead of asking an AI.

Full handoff at `/mnt/c/Users/popov/Downloads/neuron-tai-alpha-handoff-2026-07-04.md` (note: its "planning artifacts missing" section is stale — ADRs 0016–0019 and `.scratch/alpha-hardening/issues/` were created in commit 68e0572).
+
+**Navigation:** `.scratch/alpha-hardening/README.md` = index + phase order; `research-verifiable-inference.md` §8 = layered fraud scheme, §9 = build-vs-adopt; ADR-0018 = flagship fraud design; `docs/agents/issue-tracker.md` = issue conventions (active work in `.scratch/<slug>/`).
+
+**Locked decisions (do not re-derive):** TOPLOC ADOPT (`pip install toploc`, teacher-forced prefill, one canonical precision per model); audit 5% default escalating on anomaly/low-rep/disputes; blame via on-demand per-hop activation commitments + bisection (fixes validator `_final_text_node` bug — it blames only the last hop); reputation = persisted graduated ×0.8-per-strike multiplier affecting routing + audit rate; full pending forfeiture stays the primary penalty; accounting becomes tracker-authoritative (count tokens from the proxied stream, work units from tracker-assigned spans — node self-reports are untrusted); strikes/bans/reputation must survive restart (RegistryWallet is RAM-only today); multi-tracker money fixes (C2/C3/C4/A3/H1) designed in ADR-0019 but implementation deferred.
+
+**Implementation state (2026-07-05):** Alpha-scoped blocker implementation is done: auth boundary + gossip + validator service token (02/01/20), persist strike/ban/reputation (05), starting credit 0 + spend cap (03), tracker-authoritative accounting (04), wallet binding proof (11), and fraud arc (06–10). `.scratch/alpha-hardening/issues/` now has 16 `done` and 6 `ready-for-human` items.
+
+**Auth foundation now available (commit 81719ed):** `packages/tracker/meshnet_tracker/auth.py` = hive HMAC (`sign_hive_request`/`verify_hive_request`, X-Meshnet-Hive-Signature/Timestamp, 300s skew) + `is_validator_token`. In the handler: `_require_role("admin"|"validator")`, `_resolve_identity()` (validator token / admin session / client-key→no-role), `_read_hive_authenticated_body()`. `TrackerServer(validator_service_token=, hive_secret=)` also read from MESHNET_VALIDATOR_SERVICE_TOKEN / MESHNET_HIVE_SECRET; CLI `--validator-service-token` / `--hive-secret`. Outgoing gossip signed via `_push_to_peers`. Tests use these fixtures — reuse the pattern in 05/03/04.
+
+**Remaining work classification:** 12–15 are multi-tracker money/Raft ordering hardening deferred beyond single-settlement alpha; 17 needs human approval for canonical duplicate US-020 renumbering. Full pytest suite re-verified 2026-07-06: 317 passed, 3 skipped, clean.
+
+**Launch-readiness grilling (2026-07-06):** Locked launch plan — devnet dev/test run now, then **real mainnet SOL/USDT** (not devnet, not a new public token) for the first cohort: friends (API clients) + hired VPS/VPC hosts (our own test infra, not third-party volunteers — stake-free, risk-free if something breaks, not a long-term topology). Pricing: clients are the only party spending real money; nodes only accumulate off-chain credit and get paid in batches (30min dev / 24h later) — a failed distribution leaves funds parked, not lost, so mainnet-vs-devnet mixups are lower-risk than initially assumed. TAI token: do NOT issue/list now — ADR-0002 already locks listing behind $50k volume + 25 nodes/15 wallets plus an unresolved securities-review gate; only a dormant mainnet mint (cheap, ~few $ SOL) for name/branding reservation is in scope, bundled with treasury-key work, not before it. Treasury custody: bare keypair file (current runbook 02) is not acceptable for real funds — plan is **free native SPL multisig** (`spl-token create-multisig`, no protocol fee unlike Squads' 0.5 SOL), 2-of-3 signers, at least one cold/offline, others one-per-hired-VPS-provider to avoid correlated compromise (not yet built — ops task, no issue filed). Stake/slash asymmetry (registry/slash is a local Python adapter per ADR-0007, not on-chain) accepted for now since hired hosts are our own infra and friends aren't node operators — revisit before opening to real third-party node operators. A mainnet-vs-devnet boot guardrail was proposed and explicitly declined by the owner given the safe-by-default money flow above.
+
+**Two new issues from this session, both `ready-for-agent`:**
+- **21 — Honest-noise calibration corpus** (`.scratch/alpha-hardening/issues/21-honest-noise-calibration-corpus.md`) rescoped from "prod gate" to a **hard alpha-release blocker**. Confirmed by code read: `verify_activation_proofs()` (`packages/validator/meshnet_validator/audit.py:94-127`) returns bool only, no raw divergence value; fleet-dispatch exists but wrong shape (`server.py:2998-3104`, pinned routes + latency, not full-fleet + TOPLOC divergence); storage wrong shape (`registry_events` has no divergence/hardware columns). Three-part build: (1) surface raw TOPLOC distance from audit.py, (2) extend dispatch to hit every registered node with fixed prompt/seed, (3) new SQLite table keyed by node+GPU+dtype. Small-fleet exception granted (N = actual hired-VPS fleet size). Hired VPS hosts stay stake-free until this closes.
+- **23 — Dynamic HF-benchmarked pricing** (`.scratch/alpha-hardening/issues/23-dynamic-hf-pricing.md`), high priority but not a release blocker. Pricing today is 100% static (`DEFAULT_PRICE_PER_1K_TOKENS = 0.02`, `billing.py:21`; `model_presets.json` has no per-model price). Target: 80% of cheapest comparable provider on `https://huggingface.co/inference/models` (per-provider-per-model marketplace, `?search=` query param works, no confirmed JSON API — plain scrape attempted first, escalate to headless browser only if the table isn't in raw HTML). Human-verified `hf_aliases` + `hf_verified_match_note` (params/quantization) per model, not auto-discovered matching. Reuses the `_settlement_loop` daemon-thread pattern for a daily refresh; falls back silently to the static default on any failure.
+
+Both are already migrated into `.scratch/alpha-hardening/prd.json` (AH-021 updated, AH-023 added) and the README index — ready for Ralph to pick up unattended.
+
+**Ralph note:** `scripts/ralph_progress.py` tracks `docs/prd.json` (35/35 done) and does NOT see `.scratch/alpha-hardening/issues/`. No ralph loop is running and no `.ralph-tui/` state exists. `.scratch/alpha-hardening/prd.json` now has 23 stories (AH-001…AH-023); point Ralph at that file for the alpha-hardening branch. Do NOT use `ralph auto --parallel` on server.py-touching issues — 21 and 23 both touch `server.py`/`billing.py`/`audit.py`; if run in the same Ralph pass, run them serially, not in parallel (merge-conflict risk, same lesson as 03/04 previously).
+
+**Why:** three audits agreed the alpha blockers are unauthenticated gossip (anyone can inject billing events), the free-credit faucet, and ephemeral bans.
+**How to apply:** work test-first per issue acceptance criteria; use `.venv`; `cryptography` belongs in node deps (wallet.py imports it — causes many of the 24 "failures" in a fresh env). See [[project-status]] and [[autonomous-work-style]].
+
+## Routing telemetry resume (2026-07-07)
+
+`.scratch/alpha-hardening/issues/24-routing-telemetry-resume.md` / AH-024 captures the interrupted Claude handoff. Learned routing is already committed at `518c259`; the dirty tree contains live-progress/current-request heartbeat/dashboard telemetry. First known blocker: `packages/tracker/meshnet_tracker/server.py:1490` uses `threading.Lock | None`, which crashes import because `threading.Lock` is a factory function at runtime. Fix that before running the targeted telemetry tests. Keep `.claude/settings.local.json` uncommitted unless explicitly approved.

+When given a backlog, work through all open tasks autonomously and report back when done. Ask questions only for implementation/architecture decisions that genuinely need his input (grilling-style, one at a time with a recommendation) — never for permission to proceed, and don't checkpoint between tasks. Running tests is ALWAYS allowed (allowlisted in settings).

+# neuron-tai — Product Selling Points
+
+## Core pitch
+Volunteer GPU network for distributed LLM inference. Small GPU owners contribute compute and earn TAI tokens. Clients get inference on models larger than any single machine can serve.
+
+## Confirmed technical differentiators (verified working)
+
+### Mixed hardware inference routes
+The tracker can chain CPU nodes and GPU nodes into a single inference route. Shard A on a CPU node → Shard B on a GPU node → valid streamed response. Each participant in the route only needs to fit *their shard* in memory, not the whole model.
+
+**Angle for landing page:** "Run a 70B model across three laptops and a gaming PC. Each machine only holds the layers it can fit."
+
+**Nuance to acknowledge:** PyTorch/HuggingFace `device_map="auto"` already does CPU+GPU mixing on a single machine. Our value-add is doing this *across machines over the network*, democratizing access to models that no single volunteer machine could serve alone.
+
+### Hardware-aware routing
+Tracker scores nodes by `benchmark_tokens_per_sec / (queue_depth + 1)` and always routes to the fastest available node per shard range. A GPU node at 11,200 throughput index beats a CPU node at 626 automatically — no user configuration needed.
+
+### Zero port-forwarding required
+Nodes connect outbound to the relay via WebSocket. Works from behind NAT, WSL2, 5G, or a home router with no config. The public tracker at ai.neuron.d-popov.com handles discovery.
+
+### OpenAI-compatible API
+Any app using the OpenAI Python SDK works by changing only `base_url`. No code changes for the client.
+
+## Landing page content TODO
+- User asked to capture these points for the landing page copy (2026-07-01)
+- No landing page file exists in the repo yet
+- When writing copy, lead with the "run models bigger than your GPU" angle, then support with mixed-hardware routing, relay, and OpenAI compat
+
+**How to apply:** When writing product descriptions, pitches, or landing page copy, use these as the primary hooks. The mixed-network inference route (CPU+GPU across machines) is the biggest differentiator vs. single-machine solutions.

+
+All 35 user stories in docs/prd.json are done (35/35), including the reward-system arc US-030…US-035 completed 2026-07-02:
+
+- **BillingLedger** (packages/tracker/meshnet_tracker/billing.py): event-sourced USDT ledger, gossip-replicated across the hive (id-deduped events), SQLite-persisted. 90/10 split by work units, per-model per-1K-token pricing, 402 before routing.
+- **Solana custodial adapter** (packages/contracts/meshnet_contracts/solana_adapter.py): urllib JSON-RPC + solders signing. NOTE: installed solana-py 0.40 has NO sync client — don't import solana.rpc.api / spl.token.client.
+- **scripts/devnet_setup.py**: creates mock-USDT mint + treasury, writes .env.devnet; --mint-to funds test clients.
+- **TrackerServer threads**: deposit watcher (exactly-once via deposit-<sig> event ids) + leader-only settlement loop (threshold OR max-period, dust floor, resend-by-settlement-id → no double-pay).
+- **Forfeiture penalty**: validator forfeits pending balance + strike; 3 strikes ban; probation redirects shares to protocol cut. Math in packages/validator/README.md.
+- **Web dashboard**: GET /dashboard on any tracker, embedded dashboard.html, 4s polling.
+- **Observed routing throughput**: tracker records rolling observed tokens/sec per `(node_id, model)` from completed proxied inference requests, exposes it via `/v1/stats` and `/v1/network/map`, shows it on the dashboard, and prefers observed per-model TPS over startup benchmark for routing when samples exist.
+
+Suite: 222 passed, 3 skipped (openai/langchain packages missing in .venv — pre-existing).
+
+**Why:** design locked in ADR-0015 (USDT custodial settlement; TAI deferred, protocol cut = future TAI liquidity).
+**How to apply:** next steps are live devnet verification (run devnet_setup.py, start tracker with --solana-rpc-url/--usdt-mint/--treasury-keypair --billing-db), then the TAI mint when volume justifies it. Work not yet committed to git as of session end — check git status.
+
+## Alpha hardening (2026-07-05)
+
+Implementation complete for alpha-scoped blockers in `.scratch/alpha-hardening/`: 16/22 issues are `done`, including auth/gossip/service-token, persisted strike/ban/reputation, zero starting credit + spend cap, tracker-authoritative accounting, wallet binding proof, TOPLOC audit primitive, hop bisection, reputation scoring/routing, adaptive audits, and penalty wiring. Remaining 6/22 are `ready-for-human` / post-alpha or ops-gated: 12–15 multi-tracker money/Raft ordering hardening, 17 duplicate US-020 renumbering approval, and 21 honest-noise calibration corpus before production audit thresholds. Current verification: `uv run pytest -k 'not test_legacy_start_without_port_uses_next_available_port'` passes 316, skips 3; full `uv run pytest` has one environmental failure while local `meshnet-node` PID 1263451 occupies port 7000.
+
+Historical handoff note: `/mnt/c/Users/popov/Downloads/neuron-tai-alpha-handoff-2026-07-04.md` is useful for navigation and original audit context, but it predates the completed `.scratch/alpha-hardening/` planning artifacts. Treat its "missing ADR/issues/README" statements as stale; prefer `.scratch/alpha-hardening/README.md` and `.scratch/alpha-hardening/handoff.md` for current task order.
+
+## Node capability admission P0 (2026-07-09)
+
+Planning is ready at `.scratch/node-capability-admission/` with five sequential Ralph stories and ADR-0023. The design is model-agnostic: a Node must validate its selected Model Artifact/shard with a bounded real forward before Tracker routing; Qwen3.6 is only an optional development fixture. P0 adds a versioned local recipe-manifest/report contract, `meshnet-node doctor`, fail-closed startup admission, and tracker route gating. It intentionally excludes dynamic recipe/dependency installation and the future signed Node updater.
+
+## Windows CUDA node (working as of 2026-07-01)
+- miniforge3 base env, torch 2.7.1+cu118, torchvision 0.22.x+cu118
+- RTX 4060 Laptop GPU, 8 GB VRAM, benchmark index ~11,200
+- Run: `meshnet-node start --tracker https://ai.neuron.d-popov.com --model Qwen/Qwen2.5-0.5B-Instruct`
+- Known: tracker registration fails with `http://` — must use `https://`
+- pynvml deprecation warning is harmless (use nvidia-ml-py to silence it)
+
+## Model cache layout (2026-07-07)
+- Node downloads now cache files directly under `<download_dir>/<model>/`, not `<model>/layers_<start>-<end>/`, so a wider cached layer assignment can satisfy a later narrower assignment without duplicate shard folders.
+- Downloader checks tracker-advertised `files` + `file_sizes` before peer/HF download; complete local files return immediately and preserve any extra files already in the model folder.
+- Verification: downloader/startup targeted subset passes (`pytest tests/test_node_startup.py -k "download_shard or same_shard"`). Full `tests/test_node_startup.py` has 46 passed and 4 unrelated Windows chmod/path separator failures.
+- Live Windows confirmation: `meshnet-node start --tracker http://192.168.0.179:8080 --model Qwen3.6-35B-A3B` reuses `F:\_STORAGE\models\qwen3.6-35b-a3b`, prints `Cached at`, registers, and reaches ready as node `5gMLrmyB-26b1f8a4204a`.
+- Follow-up fix: preset-model startup now starts the heartbeat thread after registration; without this, the node appeared briefly on the dashboard and was purged on first inference/route after heartbeat expiry. Tracker dashboard now has a "Console output" panel backed by `/v1/console` for node register/expiry, routing failures, and proxy events.
+- Qwen3.6-35B-A3B CPU runtime cap (2026-07-08): the old reserve-based split could assign an 79 GB CPU node layers 0-36, but real partial loading can exceed that budget and die without a Python traceback. Node startup now clips oversized CPU auto-assignments before loading, and tracker CPU assignment uses a stricter runtime headroom factor; do not revert this to the old 20% reserve-only policy.
+- Route hardening: tracker chat proxy and `/v1/route` diagnostics now use alias-aware preset node matching for split Qwen3.6 routes; dashboard derives grouped inference history from proxy route/complete console events and shows observed TPS after completion.
+- Live proxy hardening: model lookup trims outer whitespace before alias matching (`qwen3.6-35b-a3b ` resolves), and tracker route logs/dashboard queue depth combine heartbeat queue with tracker-local proxy in-flight counts so Postman-style bursts no longer show every selected route as queue `0`.
+- Split-shard streaming hardening: Qwen3.6-style distributed generation now emits SSE chunks token-by-token from the head node instead of buffering all generated text until completion. Tracker direct/relay stream proxy logs `proxy progress` with live tokens/TPS, dashboard Inference history shows currently processing requests with live TPS/tokens/queue, and relay stream completion no longer references an undefined `session_id`.
+- Native Windows Qwen3.6-MoE import fix: `flash-linear-attention` imports `triton`; without `triton-windows`, startup fails with misleading `Could not import module 'Qwen3_5MoeForCausalLM'`. Installed `triton-windows` in `C:\Users\popov\miniforge3` and added it as a Windows-only node dependency.

+- **[21 — Honest-noise calibration corpus](./issues/21-honest-noise-calibration-corpus.md)** — rescoped from "prod gate" to a hard **alpha-release blocker**. `Status: ready-for-human` — engineering (audit.py raw divergence, tracker dispatch endpoint, SQLite corpus, p99 envelope) done 2026-07-06; blocked on a human running the calibration job against the real hired-VPS fleet before launch.
+- **[23 — Dynamic HF-benchmarked pricing](./issues/23-dynamic-hf-pricing_completed.md)** — new, high priority but not a release blocker. `Status: done` — engineering complete 2026-07-06 (hf_pricing.py, opt-in daily refresh loop, GET /v1/pricing/hf/history); real `hf_aliases` curation per model is a follow-up human sign-off, not a completion blocker.
+
+Locked scope: one settlement tracker, open node join, devnet mock-USDT, reputation carries forward → fraud must be bounded. See [ADR-0016](../../docs/adr/0016-alpha-scope-and-known-limitations.md).
+
+**Resume task (2026-07-07):** [24 - Routing telemetry resume](./issues/24-routing-telemetry-resume.md) is `ready-for-agent`. Learned-routing commit `518c259` is already present; dirty tree contains current-request heartbeat/dashboard telemetry and a known import-time annotation crash in `server.py:1490`.
+
+**Perf follow-up (2026-07-08):** [25 — Sharded per-node KV cache for distributed generation](./issues/25-per-node-kv-cache-distributed.md) is **implemented** ([ADR-0022](../../docs/adr/0022-sharded-per-node-kv-cache.md)): per-generation session ids, prefill/decode wire protocol (`X-Meshnet-Cache`/`X-Meshnet-Past-Len`), per-node sharded `DynamicCache(config=…)` (hybrid-attention-aware), TTL+LRU eviction with 409 cache-miss → full re-prefill fallback. Golden test proves token-identical output vs the stateless path; CPU two-shard measurement: 7.05 tps decaying 32% → 18.93 tps flat (2.68×). Remaining: re-measure on the live 2-node GPU topology and the Qwen3.6-35B-A3B mixed topology.

+# neuron-tai — Alpha Hardening Handoff
+
+**Date:** 2026-07-04  
+**Repo:** `D:/DEV/git.d-popov.com/neuron-tai`  
+**Prior session:** Pre-release alpha audit + grilling (design locked; planning artifacts complete)
+
+---
+
+## 1. Mission / where we are
+
+neuron-tai is a volunteer-GPU, pipeline-parallel LLM inference network with a working routing layer and a **broken money/trust path**. Three independent audits agreed: unauthenticated gossip, free-credit faucet, double-pay risks, ephemeral bans, and node self-reported accounting undermine alpha release. The owner locked alpha scope (single settlement tracker, open node join, devnet mock-USDT, carried-forward reputation) and a fraud/verification design (TOPLOC adoption, adaptive audits, on-demand hop bisection, persisted graduated reputation, tracker-authoritative accounting). **Research and planning artifacts are complete** (ADRs 0016–0019, 22 issue files, README index). Next: implement Bucket 1 blockers test-first.
+
+---
+
+## 2. Locked decisions

+| Reputation: graduated multiplier (×0.8-per-strike shape), persisted, affects routing + audit rate | Locked | ADR-0018 §6; `packages/validator/README.md` |
+| Penalty: **full pending forfeiture** is primary hammer (19× deterrence at 5% audit); ×0.8 is routing/payout decay | Locked | Research §1.1; ADR-0018 §1 |
+| Accounting: tracker authoritative — count tokens from proxied stream; work units from **tracker-assigned** shard span | Locked | ADR-0018 §5; issue 04 |

+# 01 — C1: Authenticate hive gossip endpoints
+
+## What to build
+
+Add authenticated peer identity to all tracker gossip mutation endpoints. Today any caller can push billing, account, and stats events without verification.
+
+**Code refs:**
+
+- `packages/tracker/meshnet_tracker/server.py` — `_handle_billing_gossip` (~2414–2427)
+- `packages/tracker/meshnet_tracker/server.py` — `_handle_accounts_gossip` (~2610–2623)
+- `packages/tracker/meshnet_tracker/server.py` — `_handle_stats_gossip` (~2355–2364)
+- `packages/tracker/meshnet_tracker/billing.py` — `apply_events` (~301–311)
+- `packages/tracker/meshnet_tracker/accounts.py` — `apply_events` (~220–226)
+
+Implement per ADR-0017 §3 using the auth helper/config from issue 02: shared hive HMAC (body + timestamp) or mutual TLS between configured tracker peers. Reject unauthenticated gossip with 401.
+
+**Note:** `/v1/gossip` (node throughput fan-out, `server.py` ~1331) is **not** in scope for this issue — see ADR-0017 §3 out-of-scope note.
+
+## Test-first
+
+1. Red: unauthenticated POST to `/v1/billing/gossip` applies a credit event today — test must fail after fix.
+2. Red: authenticated peer with valid HMAC applies events; invalid/missing auth returns 401 and `applied: 0`.
+3. Green: wire the issue-02 verifier/config (`--hive-secret` or peer cert paths) into the three hive mutation endpoints.
+
+## Acceptance criteria
+
+- [ ] `/v1/billing/gossip`, `/v1/accounts/gossip`, `/v1/stats/gossip` reject requests without valid hive auth
+- [ ] Authenticated peers replicate events as today (id-dedup preserved)
+- [ ] Config documented for multi-tracker dev setups

+# 02 — A2: Unified auth boundary for privileged and financial reads
+
+## What to build
+
+Replace header-presence stubs with a single auth middleware that resolves API keys, admin sessions, validator service tokens, and hive peer identity. Close leaks on financial and operator endpoints. This is the auth foundation issue; issue 01 should only apply hive auth to gossip endpoints once the helper exists.
+
+**Code refs:**

+- `packages/tracker/meshnet_tracker/accounts.py` — `session_account()`, `create_session()` only (session store; not handler wiring)
+
+Per ADR-0017 §4: forfeit → validator or admin; benchmark → admin; billing summary/settlements/registry wallets → admin session. Include the validator service token shape from `20-validator-service-token_completed.md` in the same implementation if practical.
+
+## Test-first
+
+1. Red: POST `/v1/billing/forfeit` with `Authorization: Bearer garbage` succeeds today — must require validator/admin identity.
+2. Red: GET `/v1/billing/summary` without admin session returns 401/403.
+3. Green: middleware + role checks; existing inference API-key path unchanged.
+
+## Acceptance criteria
+
+- [ ] Single `_require_auth(role=...)` (or equivalent) used by all privileged handlers
+- [ ] Shared auth config supports admin sessions, validator service token, and hive peer HMAC/mTLS
+- [ ] Forfeit accepts only validator service token or admin session — not arbitrary Bearer strings
+- [ ] Financial read endpoints require admin session (alpha posture)
+- [ ] Benchmark write/read require admin or service token
+- [ ] Integration tests for each endpoint class (reject unauth, accept valid)

+# 04 — H2: Tracker-authoritative token and work-unit accounting
+
+## What to build
+
+Stop trusting node-reported usage for billing. The tracker already proxies responses — use tracker-observed response data and request limits to cap billable tokens, and compute work units from the **route it constructed**, not node declarations.
+
+**Code refs:**
+
+- `packages/tracker/meshnet_tracker/server.py` — `node_work` from route construction (~1776–1782, ~1781–1782)

+- `packages/tracker/meshnet_tracker/billing.py` — `charge_request` node_work split (~104–151)
+
+Accounting fraud = inflating tokens or shard span. Per ADR-0018 §5.
+
+## Test-first
+
+1. Red: mock upstream returns inflated `usage.total_tokens` in body but tracker bills that value — test expects the tracker to cap billable tokens from observed stream chunks or request bounds.
+2. Red: node registers false `shard_end`; billing uses tracker route span, not registration field alone.
+3. Green: authoritative counters; ignore node-reported work units on charge path.
+
+## Acceptance criteria
+
+- [ ] Streaming token count uses tracker-observed chunks/tokens; upstream `usage.total_tokens` can only lower or match that observed count, never inflate it
+- [ ] Non-streaming token count caps upstream `usage.total_tokens` by tracker-known request bounds (`max_tokens`, and prompt estimate if available); exact tokenizer-backed counts are deferred unless already available locally
+- [ ] Work units = tracker-computed layer span per hop at route build time (~1781–1782)

+
+## What to build
+
+Registry strike/ban/reputation state today lives in RAM-only `_LocalContractState` — tracker restart wipes penalties. Persist to SQLite (same pattern as `BillingLedger` and `AccountStore`) so reputation carries forward per ADR-0016 §4.

+
+Include fields for: `strike_count`, `banned`, `completed_job_count`, graduated **reputation score** (float, default 1.0), `last_audit_ts`, probation tracking.
+
+**Scope split:** this issue owns **schema + persistence + load/reload** only. Reputation **scoring deltas** (audit pass/fail adjustments, decay rules) belong in issue 08.
+
+## Test-first
+
+1. Red: record strike, restart tracker process, strike count is 0 — must fail.

+# 06 — FRAUD: TOPLOC integration (teacher-forced audit primitive)
+
+## What to build
+
+Adopt [TOPLOC](https://github.com/PrimeIntellect-ai/toploc) (MIT, `pip install toploc`) for activation fingerprint commit and verify. Replace string-equality validator checks with teacher-forced prefill + TOPLOC tolerance matching.
+
+**Estimated effort:** 2+ sessions. First landing should be the validator-only TOPLOC primitive and docs; node runtime commitments/on-demand capture can follow in issue 07 if this grows.
+
+| Subtask | Owner package | Deliverable |
+|---|---|---|
+| Validator audit primitive | `packages/validator/` | Teacher-forced prefill, TOPLOC verify, unit tests with stub tensors |
+| Node runtime commitments | `packages/node/` (if prover-side) | On-demand activation fingerprint generation on audit-selected requests; move to issue 07 if it blocks the validator primitive |
+
+**Code refs:**

+- `packages/validator/README.md` — deterrence math (update for 19× at p=0.05)
+- Research: `.scratch/alpha-hardening/research-verifiable-inference.md` §8 layers 1–2, build-vs-adopt table
+
+Pin one canonical precision/quantization per model preset. Add `toploc` to validator (and node if prover-side) dependencies.
+
+## Test-first
+
+1. Red: validator compares final text strings — fails on cross-GPU honest divergence (document expected).
+2. Green: stub activation tensors + TOPLOC proofs round-trip in unit test.
+3. Integration: reference node teacher-forces tokens; verify accepts honest proof, rejects swapped precision.
+
+## Acceptance criteria
+
+- [x] `toploc` dependency declared; `build_proofs_*` / `verify_proofs_*` wired
+- [x] Validator re-runs claimed token sequence as prefill, not free generation
+- [x] Model preset documents canonical dtype/quantization

+# 07 — FRAUD: On-demand commitment + hop bisection blame
+
+## What to build
+
+On audit selection, require nodes to supply TOPLOC-style fingerprints of **output boundary activations** per hop (on-demand, brief retention). On verify failure, referee identifies the **first divergent hop** — not always the last text node.
+
+**Code refs:**
+
+- `packages/validator/meshnet_validator/__init__.py` — `_slash_route`, `_final_text_node` bug (~102–140) — blames `max(shard_end)` only
+- `packages/tracker/meshnet_tracker/server.py` — route hop construction (~1774–1783) — cut-points for bisection
+- Research: `.scratch/alpha-hardening/research-verifiable-inference.md` §1.2, §8 layer 3 (Verde **pattern**, not on-chain game)
+
+## Test-first
+
+1. Red: two-hop route, corrupt hop-0 activations — `_final_text_node` blames hop-1 — test must fail.
+2. Green: bisection selects hop-0; forfeit targets hop-0 wallet.
+3. On-demand: commitment requested only when audit flag set on proxied request.
+
+## Acceptance criteria
+
+- [x] Audit requests carry tracker RNG/VRF flag indistinguishable from normal traffic (research §6) — the existing post-hoc `sample_rate` RNG gate in `ValidatorProcess.validate_once` already decides audit selection after the original proxied request completed, so the request the client/nodes saw is unaffected either way; locked in by `test_hop_commitments_are_not_requested_unless_the_event_is_audit_selected`
+- [x] Nodes retain recent boundary activations for on-demand commit window (configurable TTL) — `ToplocAuditConfig.commitment_ttl_seconds`; expired commitments fall back to the text-only path (`test_expired_commitment_window_falls_back_to_text_only_audit`)
+- [x] Validator/tracker compares fingerprints at each hop cut-point; first mismatch = culprit — `_hop_commitments_from_event` + `_first_divergent_hop` in `packages/validator/meshnet_validator/__init__.py`
+- [x] `_final_text_node` removed or limited to text-only fallback — only called from the plain-text divergence branch of `_validate_event` now
+- [x] Integration test: multi-hop pipeline, fault injected at known hop — `tests/test_hop_bisection.py`

+# 08 — FRAUD: Reputation model + persistence
+
+## What to build
+
+Implement graduated reputation per ADR-0018 §6: score derives only from tracker audit outcomes + uptime/latency. Slow build, instant loss, inactivity decay. ×0.8 routing multiplier per strike (not whole penalty — forfeiture stays full pending).
+
+**Scope split:** issue 05 owns **schema + SQLite persistence**; this issue owns **scoring rules** (deltas, decay, strike→multiplier wiring) on top of persisted fields.
+
+**Code refs:**
+
+- `packages/contracts/meshnet_contracts/__init__.py` — extend `RegistryWallet` / persistence from issue 05
+- `packages/validator/meshnet_validator/__init__.py` — `_slash_route` forfeiture path (~125–133)
+- `packages/tracker/meshnet_tracker/billing.py` — `forfeit_pending` (~280–292)
+- Research: `.scratch/alpha-hardening/research-verifiable-inference.md` §6
+
+## Test-first
+
+1. Red: persisted reputation/strike fields from issue 05 are ignored by scoring/routing today.
+2. Green: clean audit +0.05 (tunable); failed audit −0.3 and strike; three strikes → ban persisted via issue-05 fields.
+3. Inactivity decay after N days without completed jobs.
+
+## Acceptance criteria
+
+- [ ] Uses `reputation_score` and strike/ban fields persisted by issue 05; does not introduce a second schema path
+- [ ] Audit pass/fail updates score with documented deltas
+- [ ] Strike applies ×0.8 multiplier to routing weight (separate from forfeiture amount)

+# 09 — FRAUD: Reputation-weighted routing + adaptive audit rate
+
+## What to build
+
+Wire reputation into route selection and audit sampling. Default network audit budget ≈5% — **not a cap**. New/low-reputation nodes: 20–30% audit rate; veterans: 2–3% floor ≥2%. Tripwires escalate rate without direct punishment.
+

+Audit selection must be unpredictable at request time (tracker RNG after commitment window opens).
+
+## Test-first
+
+1. Red: uniform 5% sample regardless of reputation — test expects higher rate for low-reputation wallet.
+2. Green: budget balancer keeps fleet-wide average ≈ configured target.
+3. Routing prefers higher reputation among equal throughput candidates.
+
+## Acceptance criteria

+- [ ] Per-wallet audit probability function of reputation (newcomer high, veteran low, floor ≥2%)
+- [ ] Fleet-wide audit budget configurable (~5% default target); over ≥1000 requests with fixed seed, measured fleet audit rate within **±1.0 percentage point** of configured target (e.g. 4.0–6.0% at 5% default)

+- `packages/validator/README.md` — update 20× → 19× at p=0.05
+
+Per ADR-0018: **full pending forfeiture** is primary penalty; ×0.8 is routing decay per strike, not partial forfeit.
+
+## Test-first
+
+1. Red: integration from issue 34 — extend with multi-hop blame wallet from issue 07.
+2. Green: node with pending balance → audit fail → pending zero, strike++, banned on 3rd, excluded from next settlement.
+3. Settlement loop skips banned wallets (~3337–3344).
+
+## Acceptance criteria
+
+- [x] Audit failure triggers forfeiture + strike in one tracker transaction — `ValidatorProcess._slash_node` (in-process) and the tracker's `_handle_billing_forfeit` handler (remote) both forfeit-then-strike synchronously in a single call path; each already existed pre-AH-010 and is exercised by `tests/test_forfeiture_penalty.py`
+- [x] Banned nodes excluded from `payables` / settlement — `BillingLedger.settle_node_payout` now clamps to the wallet's *current* pending balance under the same lock as the debit, and `_settlement_loop` rechecks ban status and uses the post-clamp amount before sending, so a forfeiture landing between the `payables()` snapshot and the actual payout can never be paid out on top of (ADR-0015 race); covered by `test_60_request_stream_bans_intermittent_first_hop_cheater_not_last_hop`
+- [x] Validator uses authenticated forfeit endpoint (issue 02) — `POST /v1/billing/forfeit` is validator-token/admin-gated (ADR-0017 §4, issue 20) and is the documented remote path (`packages/validator/README.md` Usage section); `test_forfeit_endpoint_requires_auth_and_forfeits` exercises the 401→200 flow. No standalone remote-validator process exists in this codebase yet (`contracts` has no networked implementation), so the in-process `ValidatorProcess` continues to call `BillingLedger.forfeit_pending` directly when co-located with the tracker — adding an HTTP-only forfeit client with no real consumer was judged out of scope/overengineering for this issue
+- [x] README: `L > 19× g` at p=0.05; pending balance = collateral — already present in `packages/validator/README.md` ("Why the penalty deters cheating")
+- [x] Integration test: 60-request fraud scenario → ban within threshold — `tests/test_forfeiture_penalty.py::test_60_request_stream_bans_intermittent_first_hop_cheater_not_last_hop`

+
+## What to build

+
+Require signed message from wallet pubkey (ed25519 via `cryptography` / solders). Reject rebinding without admin or signed release. Use explicit overwrite policy — today `~351` overwrites binding directly; gossip apply must reject conflicting binds instead of silently clobbering.

+- `conftest.py` adds every `packages/*` dir to `sys.path`, so first-party imports (e.g. `meshnet_node.wallet`) resolve without an editable install of that package — but third-party deps like `cryptography` still must be installed separately. Added `cryptography>=41` to the root `pyproject.toml` `dev` extra so `pip install -e ".[dev]"` alone covers the wallet tests (`test_node_startup.py`, `test_wallet_binding_proof.py`, `test_devnet_treasury.py`, etc.) without requiring a full `packages/node` install (which would otherwise pull in torch/transformers/accelerate/bitsandbytes).

+# 20 — Validator service token for `/v1/billing/forfeit`
+
+## What to build
+
+Define and implement a **validator service token** distinct from client API keys and admin sessions. The validator process must authenticate when calling `POST /v1/billing/forfeit`; arbitrary Bearer strings and client API keys must be rejected. This is a checklist subtask for issue 02 and should normally land in the same PR as the unified auth middleware.
+
+Per [ADR-0017 §4](../../docs/adr/0017-tracker-authentication-and-authorization.md): forfeit accepts **validator service identity or admin session** only.
+
+## Configuration
+
+| Item | Alpha default |
+|---|---|
+| Env var | `MESHNET_VALIDATOR_SERVICE_TOKEN` (tracker + validator) |
+| Config flag | `--validator-service-token` / tracker config file equivalent |
+| Header format | `Authorization: Bearer <service-token>` with a dedicated prefix or separate header scheme documented in runbooks (e.g. `Authorization: Service <token>` — pick one and test consistently) |
+| Rotation | Manual: set new token on tracker + validator, restart both; document zero-downtime rotation as post-alpha |
+
+## Rejection rules
+
+- Client API keys (`sk-mesh-…`) → **403** on forfeit (even if valid for inference)
+- Non-empty garbage Bearer → **401/403**
+- Missing auth → **401**
+- Valid validator service token → **200** (existing forfeit semantics)
+- Admin session → **200** (operator override)
+
+## Test-first
+
+1. Red: validator (or test client) posts forfeit with a valid API key — must fail after fix.
+2. Red: `Authorization: Bearer garbage` — must fail (covered by issue 02; this issue defines the accepted token).
+3. Green: configured service token succeeds; wrong token fails.
+
+## Acceptance criteria
+
+- [ ] Service token configurable via env/flag on tracker and validator
+- [ ] Unified auth middleware resolves service token → `validator` role (issue 02)
+- [ ] API keys explicitly rejected on forfeit path
+- [ ] Integration test: validator client with service token forfeit succeeds; API key forfeit fails

+
+**BLOCKS ALPHA RELEASE.** Scoped 2026-07-06 during alpha-launch-readiness grilling session — must complete before real-money (mainnet SOL/USDT) traffic goes live for the friends + hired-VPS-host launch. Loose/uncalibrated thresholds + manual admin slash-reversal are the stopgap only until this closes.
+
+**Engineering complete 2026-07-06; blocked on a human running it against the real hired-VPS fleet before launch.** The three code gaps below are closed and unit-tested (see Deliverables), but nothing in a dev session can stand in for actually dispatching the job at real hardware — that step, plus the threshold/FPR write-up that depends on its output, needs an operator with the live fleet. See the validator README's "Honest-noise calibration corpus" section for the operational how-to.
+
+# 21 — Honest-noise TOPLOC calibration corpus
+
+## What to build
+
+Before enabling production TOPLOC audit thresholds, collect an **honest-noise baseline** across the active fleet. Run identical inference jobs on every active node/GPU combo; measure the divergence envelope (TOPLOC exponent/mantissa deltas, logprob-rank spread) under real hardware variance. This must be driven by the tracker (scheduled/dispatched job), not a manual one-off script, so it can be re-run as the fleet's hardware mix changes.
+
+Per [ADR-0018 consequences](../../docs/adr/0018-fraud-detection-verification-and-reputation.md): threshold calibration requires an honest-noise corpus across the fleet before production thresholds.
+
+Research anchor: `.scratch/alpha-hardening/research-verifiable-inference.md` §8 layer 3 — "collect this first — run identical jobs across the current node fleet to measure the honest divergence envelope before setting thresholds."
+
+**Launch context (why this is buildable now, not a research project):** first-launch nodes are hired VPS/VPC hosts under our own direct control (test infrastructure we pay for, not third-party volunteers) — not a long-term topology, but risk-free for calibration purposes since there's no external party to dispute a bad reading. Friends are client-side users of the API in this phase, not node operators. Run the calibration pass against this small, fully-controlled fleet first; hired hosts stay stake-free until it's done, then move to real staking once thresholds derive from their own hardware.
+
+**Current gap (confirmed 2026-07-06 by code read):** none of the three pieces below exist yet.
+
+1. `verify_activation_proofs()` (`packages/validator/meshnet_validator/audit.py:94-127`) returns a **plain bool** — no raw TOPLOC divergence/distance value is ever computed or surfaced. Every "done" fraud-detection issue (06–10) currently runs on a guessed threshold baked into that bool, not a calibrated one.
+2. Fleet dispatch exists but is the wrong shape: `_handle_benchmark_hop_penalty` / `_handle_benchmark_results` (`packages/tracker/meshnet_tracker/server.py:2998-3104`, from the old US-030 latency work) targets pinned 1–3-node *routes* and measures latency, not TOPLOC divergence across *every* registered node.
+3. Storage is the wrong shape: `record_audit_outcome` (`packages/contracts/meshnet_contracts/__init__.py:416`) persists only `strike_count`/`banned`/`passed` to `registry_events` — no divergence value, no GPU/dtype/hardware-profile column anywhere. Benchmark results otherwise land in a flat JSON file (`server.benchmark_results_path`), not a queryable per-node/hardware schema.
+
+## Deliverables
+
+- [x] Extend the TOPLOC verify call path (`audit.py`) to return the raw distance/divergence metric alongside the existing bool — `verify_activation_proofs_detailed()` / `ToplocVerificationResult` in `packages/validator/meshnet_validator/audit.py`; `verify_activation_proofs()` kept as a thin bool-only wrapper for existing callers. Also fixes a real bug this issue's code-read surfaced: the old code did `bool(_call_toploc(...))`, which is always `True` for the real `toploc` library's non-empty per-chunk `VerificationResult` list regardless of divergence — `tests/test_toploc_audit.py::test_verify_activation_proofs_detailed_aggregates_per_chunk_divergence` exercises this directly.
+- [x] Extend the existing fleet-dispatch pattern (`server.py:2998+`) from pinned-route benchmarking to a tracker-scheduled job that hits **every currently registered node** with a fixed prompt/model/seed — `POST /v1/calibration/toploc/run` (admin/validator-gated, same shape as `POST /v1/benchmark/hop-penalty`) in `packages/tracker/meshnet_tracker/server.py`. Dispatches to every node that can solo-serve the full model range (single-hop pinned route, isolating one node's hardware noise from route-composition effects); partial-shard nodes are reported under `skipped_partial_shard_node_ids`, and nodes that don't answer the on-demand TOPLOC commitment fetch are reported per-node under `"skipped": "..."` rather than counted as pass or fail. See `tests/test_toploc_calibration_dispatch.py`.
+- [x] Add a small SQLite table (same pattern as `billing.py`/`accounts.py`) keyed by node wallet + GPU model + dtype, storing the divergence value per calibration run — `packages/tracker/meshnet_tracker/calibration.py::ToplocCalibrationStore`, `toploc_calibration_runs` table.
+- [x] Aggregation: p99 honest envelope + safety margin computed from that table, written as the recommended tolerance constants — `ToplocCalibrationStore.envelope()`, exposed via `GET /v1/calibration/toploc/results`.
+- [x] Gate checklist: production audit enable blocked until corpus covers ≥N distinct hardware profiles — `ToplocCalibrationStore.gate_status(min_hardware_profiles=N)`; N is `--toploc-calibration-gate-min-hardware-profiles` (default 1) on the tracker CLI, documented alpha exception in the validator README.
+
+## Acceptance criteria
+
+- [ ] Corpus collected from the current hired-VPS fleet (documented as a small-fleet alpha corpus, not the eventual volunteer-fleet corpus) — **not done: needs a human to run `POST /v1/calibration/toploc/run` against the live hired-VPS fleet before launch; no such fleet exists in a dev session.**
+- [ ] Threshold constants in validator config derived from corpus, not guessed — mechanically ready (`envelope()` returns them) but depends on the real corpus above; not yet wired into `ToplocAuditConfig` as enforced thresholds (deliberately — enforcing unvalidated thresholds would be worse than today's guessed bool).
+- [ ] False-positive rate estimate documented at chosen thresholds — `envelope()` returns `estimated_false_positive_rate` (in-sample: fraction of the recorded corpus the recommended thresholds would themselves flag); needs the real corpus to be a meaningful number, and should be written up in the runbook once collected.
+- [x] README / runbook cross-link: **do not enable production audits** until this issue closes — `packages/validator/README.md` "TOPLOC audit contract" section, updated with the full operational how-to.
+- [x] Note in the runbook that this alpha corpus must be re-run once the fleet grows beyond the hired-VPS set (different hardware mix invalidates the envelope) — same README section.

+Scoped 2026-07-06 during alpha-launch-readiness grilling session. High priority, ship-soon for launch — **not** an alpha-release blocker (unlike issue 21): a stale/static price is a revenue/business-model risk, not a safety risk, so the friends + hired-VPS launch may proceed on the current static default while this lands in parallel.
+
+# 23 — Dynamic per-model pricing benchmarked against HuggingFace inference rates
+
+## What to build
+
+Client-facing price per model should track the market: **80% of the cheapest comparable provider rate on HuggingFace's inference marketplace** (`https://huggingface.co/inference/models`), refreshed daily, auto-adjusting so served models stay competitively priced as the market moves. Nodes are unaffected by this loop (per launch design: clients are the only party spending real money; node payouts come from the 90/10 split of whatever price is charged, per ADR-0015/`packages/validator/README.md`).
+
+**Current state (confirmed by code read 2026-07-06):** pricing is 100% static today. `DEFAULT_PRICE_PER_1K_TOKENS = 0.02` (`packages/tracker/meshnet_tracker/billing.py:21`) is the fallback nearly every model hits, since `model_presets.json` currently has no `price_per_1k_tokens` key for any preset. `BillingLedger.set_price(model, price)` (`billing.py:67-69`) is the only write path and already exists — no CLI/admin route calls it yet. No external HTTP/market-data integration exists anywhere in the tracker.
+
+**Data source:** `https://huggingface.co/inference/models` aggregates multiple providers (novita, together, fireworks-ai, deepinfra, etc.) with per-model, per-provider $/1M input and output token pricing; the "cheapest" badge already identifies the lowest-cost provider per model on the page itself. It supports a GET query param for filtering, e.g. `?search=GLM`. **No confirmed public JSON API was found** during this session's fetch — the page reads as a rendered table. Owner's suggestion: try a plain `requests` + BeautifulSoup scrape first; if the pricing table turns out to be client-rendered (not present in the initial HTML), that's the fallback signal to escalate to a headless-browser fetch (e.g. Playwright) — confirm which is needed during implementation before building the full pipeline around it. Another data source is acceptable if more convenient/stable, owner is not wedded to this specific page.
+
+## Deliverables
+
+- [x] Live-fetch attempt (requests + BeautifulSoup against the HF page with `?search=<model-family>`, or an equivalent stable source) as the primary path — confirm during implementation whether the pricing table is present in the raw HTML or requires a headless-browser fetch, and note which in the PR
+- [x] Extend `model_presets.json` per model with: `hf_aliases` (curated list of comparable HF model+provider IDs — **human-verified, not auto-discovered**), `hf_verified_match_note` (free text: params count + quantization confirmation, so a human signs off once per alias that it is a fair comparable before it's used for auto-pricing), `hf_last_price_per_1k` (derived from the $/1M rate), `hf_last_updated` (ISO date)
+- [x] Daily refresh job reusing the tracker's existing daemon-thread pattern (`_settlement_loop`/`_deposit_loop` in `server.py`, `threading.Event().wait(interval)` loop) — for each preset with a non-empty `hf_aliases` list, fetch current pricing for those aliases, compute `0.8 × cheapest matched alias price`, call `set_price()`, and update `hf_last_price_per_1k`/`hf_last_updated`
+- [x] Every price change logged (old price, new price, source alias, timestamp) — needed for dispute auditability if a client questions a charge
+- [x] Fallback behavior: empty/missing `hf_aliases`, fetch failure, or no verified match → silently keep the existing static default price. Never error the pricing path, never zero-price a model
+
+## Acceptance criteria
+
+- [x] At least one model preset has a working end-to-end refresh (alias → live fetch → 80% computed price → `set_price()` called → metadata updated) demonstrated in a test
+- [x] Models without a curated/verified alias continue to use the static default, unaffected by this feature
+- [x] Fetch failures (network error, page structure change, no match found) degrade gracefully — logged, not raised to the request path
+- [x] Price-change log is queryable/inspectable (doesn't need a UI yet — a log line or table row is sufficient for alpha)
+- [x] Note in the runbook/issue on which fetch mechanism (plain HTTP scrape vs. headless browser) was actually required, so the next person doesn't have to rediscover it
+
+## Implementation notes (2026-07-06)
+
+**Fetch mechanism confirmed: plain HTTP scrape, no headless browser needed.** Live-fetched `https://huggingface.co/inference/models?search=GLM` this session — the pricing table is server-rendered into the initial HTML response (SvelteKit SSR), confirmed by grepping the raw response for `cheapest`/`$`-prefixed price cells before any JS runs. A stdlib `urllib.request` GET + `html.parser.HTMLParser`-based table walk is sufficient; no `requests`/`bs4`/Playwright dependency was added, matching this package's existing zero-new-HTTP-dependency convention (`gossip.py`/`raft.py`/`server.py` all use `urllib.request` only). Each row's most stable extraction anchor turned out to be the `<a href="/<org>/<repo>/?inference_api=true&inference_provider=<provider>">` link, not the display text (which duplicates the repo id at two responsive breakpoints and is easy to mis-parse).
+
+**What shipped:** new `packages/tracker/meshnet_tracker/hf_pricing.py` — pure HTML parser (`parse_hf_pricing_table`), alias matching (`cheapest_matching_quote`, supports both `org/repo` and `org/repo::provider` forms so a human can pin a specific provider's deployment), a pure per-preset computation function (`refresh_preset_price`, never raises), and `HfPricingLog` (SQLite-backed change log, same shape as `billing.py`/`calibration.py`). `TrackerServer` gained an opt-in (`enable_hf_pricing=True` / `--enable-hf-pricing`) daily daemon thread (`_hf_pricing_loop`, same `threading.Event().wait(interval)` shape as `_settlement_loop`) and `GET /v1/pricing/hf/history` (admin/validator-gated, mirrors `/v1/calibration/toploc/results`). `model_presets.json`'s `kimi-k2.7` preset now carries the `hf_aliases`/`hf_verified_match_note` schema fields, left as an empty list pending a human sign-off on a genuinely comparable HF listing (params count + quantization) — per this issue's own "human-verified, not auto-discovered" requirement, an agent should not fabricate that sign-off. This also means the shipped default config demonstrates the required "no alias → static price, unaffected" fallback for a real production preset; the alias→live-fetch→80%→set_price() path is demonstrated end-to-end against an injected fetch backend in `tests/test_hf_pricing_dispatch.py` (the `fetch_html=`/`hf_pricing_fetch_html=` injection point mirrors this codebase's `backend=` convention for anything that would otherwise hit the network in tests).
+
+**Bug caught and fixed while wiring this in:** `TrackerServer` previously did `dict(DEFAULT_MODEL_PRESETS)` when no explicit `model_presets` was passed — a shallow copy that aliases every preset's inner dict to the shared module-level global. Writing `hf_last_price_per_1k`/`hf_last_updated` in place would have leaked across every other `TrackerServer` instance in the same process (real risk in the test suite, and in any future multi-tracker-in-one-process embedding). Fixed with a `_clone_model_presets()` helper that also shallow-copies each preset dict.
+
+**Follow-up for a human (not a completion blocker):** populate real `hf_aliases`/`hf_verified_match_note` entries for production presets once someone has confirmed a genuinely comparable HF-listed deployment (params + quantization) — that activates dynamic pricing for that model on the next refresh tick. Until then every preset safely stays on its static price.
+
+Tests: `tests/test_hf_pricing.py` (11 tests: parsing, blended-price math, alias matching incl. provider-scoped aliases, all three fallback paths, log persistence) + `tests/test_hf_pricing_dispatch.py` (5 tests: full TrackerServer end-to-end refresh, unaffected-without-alias, history auth gating, history content, history model filter). Full suite (`pytest tests/ -q -k "not integration"`): 346 passed, 2 skipped.

+Status: ready-for-agent
+
+Scoped 2026-07-07 from an interrupted Claude session. This is a resume/cleanup task for routing and live-progress work that is partly committed and partly left dirty in the working tree.
+
+# 24 - Finish learned-routing telemetry and live-progress cleanup
+
+## Current state
+
+The main dynamic routing feature is already committed at `518c259` (`routing improvements - dynamic (wip)`):
+
+- `packages/tracker/meshnet_tracker/routing_stats.py` - decayed-EWMA route stats store, epsilon-greedy route selection, diagnostics.
+- `packages/tracker/meshnet_tracker/server.py` - route enumeration per head, bandit selection in the chat proxy, epoch bumps on node join/leave, `/v1/routing`, route sample recording with 8-token hygiene.
+- `packages/tracker/meshnet_tracker/cli.py` - `--route-explore-share`, `--route-weight-alpha`, `--route-stats-half-life` and env vars.
+- `packages/tracker/meshnet_tracker/dashboard.html` - "Routing (learned)" panel.
+- `docs/adr/0021-dynamic-statistical-routing.md` - design record.
+- `tests/test_dynamic_routing.py` - includes the exact GPU(0-21)+CPU(0-39) topology, hybrid downstream `start_layer=22`, 0.6/0.4 traffic split for a 1.5 TPS ratio, and scout-rate behavior.
+
+The current working tree still has uncommitted follow-up work:
+
+- `packages/node/meshnet_node/torch_server.py` - tracks in-flight chat requests, exposes `TorchNodeServer.current_requests`, prints generation progress with TPS.
+- `packages/node/meshnet_node/startup.py` - sends `current_requests` in heartbeat payloads and increases heartbeat cadence while busy.
+- `packages/tracker/meshnet_tracker/server.py` - accepts heartbeat `current_requests`, includes them in `/v1/network/map`, and logs `proxy connecting` before upstream connection.
+- `packages/tracker/meshnet_tracker/dashboard.html` - enriches the call wall from heartbeat `current_requests` so active requests remain visible even before terminal proxy events.
+- `tests/test_real_model_backend.py` and `tests/test_tracker_routing.py` - targeted coverage for current-request snapshots, heartbeat sanitization/storage, and TPS progress logging.
+- `QUICKSTART.md` - documents optional linear-attention fast-path packages for Qwen3.5/3.6 GPU nodes.
+
+There is also an untracked local file, `.claude/settings.local.json`, which should not be included unless the owner explicitly wants local Claude settings committed.
+
+## Known blocker found during resume
+
+Targeted pytest currently fails during import before reaching the new tests:
+
+```text
+TypeError: unsupported operand type(s) for |: 'builtin_function_or_method' and 'NoneType'
+```
+
+Immediate cause: `packages/tracker/meshnet_tracker/server.py:1490` annotates `ws_lock: threading.Lock | None = None`. `threading.Lock` is a factory function at runtime, not a type, so `| None` evaluates eagerly and crashes. This exists on `HEAD` too, not just in the dirty telemetry changes.
+
+Fix options:
+
+- Add `from __future__ import annotations` at the top of `server.py`, then run enough tests to catch any annotation side effects.
+- Or change that annotation to a safe runtime type such as `Any | None` / remove the union annotation. Keep the change minimal.
+
+## What to do next
+
+1. Fix the import-time `threading.Lock | None` crash.
+2. Re-run the targeted tests:
+
+   ```bash
+   .\.venv\Scripts\python.exe -m pytest tests/test_tracker_routing.py::test_tracker_heartbeat_stores_current_requests tests/test_tracker_routing.py::test_normalize_current_requests_sanitizes_payload tests/test_real_model_backend.py::test_current_requests_snapshot_while_generating tests/test_real_model_backend.py::test_distributed_generating_log_includes_tps -q
+   ```
+
+3. Run the relevant routing regression tests:
+
+   ```bash
+   .\.venv\Scripts\python.exe -m pytest tests/test_dynamic_routing.py tests/test_tracker_routing.py -q
+   ```
+
+4. If practical, run the non-integration suite:
+
+   ```bash
+   .\.venv\Scripts\python.exe -m pytest tests/ -q -m "not integration"
+   ```
+
+5. Confirm or document the pre-existing failure from the interrupted session: `test_proxy_chat_splits_payout_by_tracker_assigned_route_span` reportedly failed on `HEAD` too and was unrelated.
+6. Commit the intentional work in two commits if it remains naturally split:
+   - learned routing is already committed in `518c259`; leave it alone unless fixing regressions there.
+   - commit the live-progress/current-request telemetry cleanup separately after tests pass.
+
+## Acceptance criteria
+
+- [ ] Importing `meshnet_tracker.server` no longer crashes on the lock annotation.
+- [ ] Current-request heartbeat payloads are sanitized and surfaced in `/v1/network/map`.
+- [ ] Node-side in-flight chat snapshots report request id, model, token count, elapsed seconds, tokens/sec, and routing completion.

The ADR-0020 mixed-topology `start_layer` bug is fixed (`518c259`, `e44abc9`, `1ecc599`); this issue is the next performance blocker in the same code path.
+
+# 25 — Sharded per-node KV cache for distributed generation (MoE/hybrid-attention aware)
+
+## What to build
+
+The distributed generation loop (`torch_server.py:515-612`, `_do_chat_completions` distributed path) currently has **no KV cache at all**: `model_backend.py` passes `use_cache: False` in every layer-forward call (lines 763, 768, 770-771), and each autoregressive step re-encodes the *entire* prompt-so-far from scratch (`backend.encode_prompt(current_text)`), re-running every layer on every node in the route for every generated token.
+
+Observed cost of this on a live 2-node Qwen2.5-0.5B GPU pipeline (layers 0-20 / 21-23): tps decayed from 22.3 (at 235 output tokens) to 12.6 (at 449 tokens) within a single generation — the expected quadratic-cost signature. On the Qwen3.6-35B-A3B mixed-topology case this collapses to ~0.07 tps even after the routing fix, partly for this reason.
+
+`X-Meshnet-Session` already exists on the wire (`torch_server.py:707`, minted fresh **per token**, not per generation) but today only labels one activation transfer for chunk reassembly/logging — it is not used to key any cached state.
+
+| Subtask | Owner package | Deliverable |
+|---|---|---|
+| Session lifecycle | `packages/node/meshnet_node/torch_server.py` | Mint session ID once per chat request (not per token); reuse across all steps of that generation; add `X-Meshnet-Seq-Len` / position header so a node can tell prefill from decode steps |
+| Per-node sharded cache | `packages/node/meshnet_node/model_backend.py` | `TorchModelShard` holds a `session_id → cache_state` map scoped to *its own* layer range only (naturally sharded — no node stores another node's KV); `forward_bytes` takes `use_cache=True` and returns/reuses `past_key_values` (or `use_cache=False` for the prefill token to keep failure/eviction simple) |
+| Prefill vs. decode split | `packages/node/meshnet_node/torch_server.py` | Step 0 sends the full prompt activation (current behavior); steps 1+ send only the newest token's hidden state (`[1, 1, hidden]`) with correct `position_ids`, cutting per-step payload from O(seq_len) to O(1) |
+| MoE / hybrid-attention state | `packages/node/meshnet_node/model_backend.py` | Cache abstraction must hold "whatever `use_cache=True` returns for this layer range," not assume standard K/V tensors — Qwen3.6's linear-attention/hybrid layers (see `[transformers] The fast path is not available...` warning already logged at startup) cache **recurrent conv/delta state**, not K/V pairs. MoE expert routing itself is layer-local and needs no cross-token cache, but confirm no expert-choice state leaks across the stateless-vs-cached boundary when `use_cache` toggles between prefill and decode |
+| Cache lifecycle | `packages/node/meshnet_node/torch_server.py` | TTL + LRU eviction per node (bounded by `max_loaded_shards`/memory budget); explicit "cache miss" response so a restarted/evicted node causes the head to fall back to a full re-prefill instead of a hard error — keep today's fully-stateless path as the recovery mode |
+| Correctness parity | `tests/` | Golden-output test: distributed multi-token output with caching enabled must match the existing stateless path token-for-token (or within sampling tolerance) for a fixed prompt/seed |
+
+**Non-goals for first landing:** cross-node cache migration/rebalancing on route change (evict + re-prefill is acceptable initially); speculative decoding; batching multiple concurrent sessions' KV within one node beyond what eviction already requires.
+
+**Code refs:**
+
+- `packages/node/meshnet_node/torch_server.py:515-612` — distributed generation loop (`current_text = current_text + token_str`, full re-encode every step)
+- `packages/node/meshnet_node/torch_server.py:690-789` — `_run_downstream_pipeline`, session minting, `X-Meshnet-Session`/`X-Meshnet-Hop-Index`/`X-Meshnet-Start-Layer` headers
+- `packages/node/meshnet_node/model_backend.py:189-201, 330-351, 763-771` — `use_cache: False` call sites, `effective_start` layer-slicing logic that any cache keying must respect
+- `docs/adr/0020-chat-streaming-live-progress-and-mixed-topology-routing.md` — prerequisite routing fix this issue builds on
+- `docs/adr/0021-dynamic-statistical-routing.md` — route selection this cache must stay compatible with (a route change mid-generation should trigger cache-miss fallback, not corruption)
+
+## Acceptance criteria
+
+- [x] A session ID is stable across all steps of one chat generation (not re-minted per token) — minted once in `_do_chat_completions`, asserted in `test_session_is_stable_and_decode_payloads_are_single_token`
+- [x] Steps after the first prefill send only the new token's activation (`[1, 1, hidden]` via `encode_next_token`) with `X-Meshnet-Cache: decode` + `X-Meshnet-Past-Len`
+- [x] Each node caches state only for its own shard's layer range (`TorchModelShard.kv_sessions`; sharding falls out of per-node layer execution)
+- [x] Cache abstraction is not K/V-shaped-only: `DynamicCache(config=model.config)` — the same construction Qwen3.6-Next's own forward uses for hybrid linear-attention conv/delta state; store treats it as opaque; `TypeError` fallback disables caching per-backend
+- [x] Bounded memory: TTL (600 s, `MESHNET_KV_TTL_SECONDS`) + LRU (8, `MESHNET_KV_MAX_SESSIONS`); miss → HTTP 409 `{"error": "cache_miss"}` → head re-prefills (tested)
+- [x] Golden-output test: cached and stateless produce identical token ids on real two-shard Qwen2.5-0.5B (`test_cached_distributed_generation_matches_stateless_golden`, passed)
+- [x] Measured (CPU two-shard proxy, 40 steps): stateless 7.05 tps w/ 32% decay → cached 18.93 tps flat, 2.68×. ⚠️ still to run on the live 2-node GPU topology
+- [x] `tests/test_two_node_pipeline.py` and `tests/test_dynamic_routing.py` pass (30 passed; 6 tmp-dir fixture errors are a pre-existing Windows temp-permission env issue, identical on clean tree)
+- [x] Design captured in [ADR-0022](../../../docs/adr/0022-sharded-per-node-kv-cache.md) incl. cache-miss/route-change interaction with ADR-0021
+
+## Notes
+
+MoE routing (router + expert FFN) is layer-local per token and does not itself need a cross-token cache — it was ruled out as the cause of the earlier Qwen3.6 garbage-output bug (that was the ADR-0020 `start_layer` double-execution). The MoE angle that *does* matter here is architecture-awareness in the cache design: don't hardcode a K/V tensor shape assumption that breaks on Qwen3.6's hybrid attention layers.

+# Verifiable Inference & Fraud Layer — Research Findings
+
+**Date:** 2026-07-04
+**Scope:** Ground the neuron-tai fraud/verification layer in 2026 state-of-the-art and in what comparable decentralized compute networks actually do.
+**Alpha context assumed throughout:** volunteer consumer GPUs (8 GB class, e.g. RTX 4060), pipeline-parallel multi-hop inference where different nodes hold different layer ranges, a single trusted tracker (coordinator), devnet mock-USDT payments but reputation that carries forward, and an owner-approved verification budget of roughly 5% redundant recomputation.
+
+---
+
+## Executive summary
+
+1. **The proven, deployed pattern for exactly our setting is: optimistic acceptance + random teacher-forced re-verification + slashing/reputation penalties.** This is what Prime Intellect runs in production for INTELLECT-2 (TOPLOC validators, random sampling, slash-and-evict) and what Hyperbolic formalized game-theoretically (Proof of Sampling). At a 5% audit rate the math works if the penalty for a caught cheat exceeds ~19× the per-job gain — which carried-forward reputation plus forfeited pending balance easily provides.
+2. **Teacher-forced logit/activation re-verification is a recognized, robust technique** — it is the core of TOPLOC (ICML 2025), Token-DiFR (2025), and log-probability auditing papers. It sidesteps autoregressive divergence entirely and is up to ~100× cheaper than the original generation because verification prefill is compute-bound while generation is memory-bound.
+3. **Bitwise output equality is unattainable across heterogeneous volunteer GPUs**; honest nodes on different hardware/batch conditions produce different tokens even at temperature 0. All robust schemes compare in *logit/activation space with tolerances* (TOPLOC exponent/mantissa thresholds, DiFR divergence scores) or force bitwise reproducibility with special kernels (Gensyn RepOps) at a performance cost.
+4. **zkML and GPU TEEs are roadmap-only.** zkML in 2025–2026 proves GPT-2-scale models in tens of seconds per inference (100–10,000× overhead); nothing near serving speed for multi-billion-parameter models. GPU confidential computing exists only on H100/Blackwell-class datacenter hardware paired with server CPUs (SEV-SNP/TDX) — categorically unavailable on consumer volunteer cards.
+5. **Layer-skipping is NOT reliably detectable by output quality.** Careful pruning of ~25% of layers keeps ~90% of benchmark scores (ShortGPT); models degrade gracefully until a sharp collapse around 20–55% removal depending on family. But any layer skipping changes hidden states and logits drastically, so per-position activation/logit comparison catches it essentially always (TOPLOC reports 100% detection of model modifications in its evals). Verify in logit space, not by eyeballing text quality.
+6. **Classic PoW is Sybil/hardware admission control, not correctness proof** — io.net's hourly PoW is the cautionary tale (it verifies a GPU exists and has claimed VRAM, nothing about job correctness). Self-computed activation checksums are *binding commitments*, not correctness proofs: a cheater simply commits to its wrong values. Commitments earn their keep only when a referee later recomputes and compares — i.e., for audit pinning and dispute bisection.
+

+
+## 1. Technique-by-technique review
+
+### 1.1 Optimistic verification + spot-checking (probabilistic deterrence)
+
+**Mechanism.** Accept results by default; re-run a random, unpredictable subset with an independent replica; punish divergences. Hyperbolic's Proof of Sampling (PoSP) paper proves a pure-strategy Nash equilibrium in which rational nodes are honest, and claims the spot-check approach adds well under 1% overhead when everyone is rational ([PoSP, arXiv:2405.00295](https://arxiv.org/html/2405.00295); [Hyperbolic spML breakdown](https://www.hyperbolic.ai/blog/spml-breakdown)). VeriLLM adds VRF-selected audit indices over Merkle-committed hidden states so verifiers can't be lazy or predictable ([VeriLLM, arXiv:2509.24257](https://arxiv.org/html/2509.24257v3)). Prime Intellect's production deployment: validators randomly sample committed batches, and "since the Inference Provider does not know which generations will be checked, they are incentivized to be honest on all generations" ([INTELLECT-2, arXiv:2505.07291](https://arxiv.org/html/2505.07291)).
+
+**Sampling math.** With independent audit probability *p* per job:
+
+- A node that cheats on every job survives *N* jobs undetected with probability (1−p)^N. At p = 0.05: ~36% survive 20 jobs, ~4.6% survive 60 jobs, ~0.6% survive 100 jobs. Detection is near-certain over any meaningful volume.
+- A node that cheats on a fraction *f* of jobs is caught per job with probability *p·f*; expected jobs until caught = 1/(p·f). At p = 0.05, f = 0.2: caught within ~100 jobs on average. Low-rate cheating stretches time-to-detection linearly — this is why the penalty must scale with accumulated stake/reputation, not per-incident.
+- **Deterrence condition (rational node):** cheating gains *g* per job and loses *L* when caught, so expected value of cheating is (1−p)·g − p·L. Honesty dominates iff **L > g·(1−p)/p ≈ 19·g at p = 0.05**. If a caught node forfeits its pending balance and a reputation that gates future routing (i.e., discounted future earnings), L is orders of magnitude above 19× a single job's margin. This is exactly the structure PoSP formalizes and the existing neuron-tai forfeiture design (pending-balance forfeiture + strikes + ban) already implements.
+
+**The verifier-incentive caveat.** Truebit identified the classic failure mode: if the system works and nobody cheats, verifiers never earn anything and stop checking; Truebit's answer was "forced errors" with jackpot payouts, and it estimated the verification tax at 500–5000% of task cost to keep independent verifiers attentive ([Truebit whitepaper §2, §4](http://people.cs.uchicago.edu/~teutsch/papers/truebit.pdf)). **This whole problem disappears in a single-tracker alpha**: the tracker audits as a protocol function paid from the protocol cut, not as a profit-seeking third party. It becomes relevant again only when verification is decentralized.
+
+**Feasibility for alpha: HIGH.** This is the anchor technique. 5% audit budget is in the same range as deployed systems (OTR proposes ρ ≈ 1% spot-checks as sufficient deterrent in a TEE-hybrid design — [arXiv:2512.20176](https://doi.org/10.48550/arxiv.2512.20176)); 5% gives comfortable margin for a young network with thin reputational stakes.
+
+### 1.2 Interactive verification / refereed delegation (Truebit-style bisection)
+
+**Mechanism.** Solver commits Merkle roots of intermediate execution states. On dispute, challenger and solver binary-search over the committed states to the first step where they diverge; a referee (smart contract or trusted party) recomputes only that single step and rules. One honest challenger suffices; the game costs O(log n) rounds ([Truebit whitepaper](http://people.cs.uchicago.edu/~teutsch/papers/truebit.pdf); [Truebit explainer, Medium](https://medium.com/truebit/truebit-the-marketplace-for-verifiable-computation-f51d1726798f)).
+
+**ML adaptation.** Gensyn's Verde adapts this to neural networks with a two-phase bisection: first narrow to the training/inference *step*, then to the single *operator* in the computational graph; the referee recomputes one operator, needing ~two orders of magnitude less compute than the full job. Crucially, Verde only works because RepOps makes execution **bitwise reproducible across heterogeneous hardware** by fixing floating-point operation order — otherwise honest nodes diverge and bisection finds spurious "fraud" ([Verde paper, arXiv:2502.19405](https://arxiv.org/html/2502.19405v1); [Gensyn Verde blog](https://blog.gensyn.ai/verde-a-verification-system-for-machine-learning-over-untrusted-nodes/)).
+
+**Mapping to our multi-hop pipeline.** Our pipeline is naturally pre-bisected: each hop's boundary activations are the "intermediate states." A workable scheme:
+
+1. Each node commits a compact fingerprint (TOPLOC-style top-k encoding, not a raw hash — see §2) of its input and output boundary activations per request.
+2. When an end-to-end audit fails, the referee (tracker) teacher-forces the full claimed token sequence through a reference model and computes reference boundary activations at each hop cut-point in one forward pass.
+3. The first hop whose committed output fingerprint diverges from the reference (beyond tolerance) while its input fingerprint matched is the culprit. No interactive game is needed at hop granularity because the number of hops is small — the referee can check all cut-points in a single replay.
+4. Bisection *within* a hop (to a layer or operator, Verde-style) is only needed if you must prove fault to a third party at fine granularity; for internal blame assignment, hop granularity is enough since payment and reputation are per node.
+
+The main adaptation cost is the referee needing enough VRAM to run the full model (or to re-run hop layer-ranges one at a time, which any 8 GB card can do for its own range).
+
+**Feasibility for alpha: MEDIUM-HIGH** in the simplified "referee replays and compares committed hop boundaries" form (no on-chain game, tracker as referee). The full trustless interactive game with bitwise-reproducible kernels is roadmap.
+
+### 1.3 zkML (zero-knowledge proofs of inference)
+
+**2025–2026 state.** The frontier moved fast but remains far from LLM serving speed:
+
+- EZKL (ONNX→Halo2) is the most-used toolkit; generic overhead is characterized as 100–10,000× native execution, and much real usage is verifiable data science rather than LLMs ([Equilibrium Labs survey](https://equilibrium.co/writing/state-of-verifiable-inference)).
+- zkGPT (USENIX Security 2025) proves a GPT-2 inference in **under 25 seconds** on a CPU server — 185× faster than the prior ZKML system ([zkGPT](https://www.usenix.org/conference/usenixsecurity25/presentation/qu-zkgpt)).
+- NanoZK (2026) proves GPT-2-scale transformer blocks in ~43 s with 6.9 KB proofs via layerwise decomposition, 52–228× faster than EZKL ([NanoZK, arXiv:2603.18046](https://arxiv.org/html/2603.18046v1)).
+- For a 7B model, one estimate puts pure-zkML verification at **over 20 minutes per inference** ([Optimistic TEE-Rollups, arXiv:2512.20176](https://doi.org/10.48550/arxiv.2512.20176)).
+- Project reality check: Modulus Labs (authored the field-defining benchmark ["The Cost of Intelligence"](https://eprint.iacr.org/2026/1063), demonstrated proving of a multi-billion-parameter LLM as a feat, not a service) was acquired by Tools for Humanity in 2024 and now does World ID cryptography ([announcement](https://world.org/blog/announcements/modulus-labs-joins-tfh-support-applied-research-world)). Giza uses ZK proofs for *small, simple* DeFi-agent models on Starknet ([Equilibrium survey](https://equilibrium.co/writing/state-of-verifiable-inference)). EZKL itself has drifted toward verifiable data science and co-SNARKs.
+
+**Honest read:** proving is ~GPT-2 scale (~1.5B params max in tens of seconds), on beefy servers, per short inference. For a volunteer network serving multi-billion-parameter models interactively, zkML is 3+ orders of magnitude away, and proof generation would crush an 8 GB consumer card regardless.
+
+**Feasibility for alpha: NONE (roadmap-only).**
+
+### 1.4 TEE / confidential computing on GPUs
+
+**What it gives.** NVIDIA H100 is the first GPU with a hardware TEE anchored in an on-die root of trust: measured/secure boot, SPDM session with a driver inside a CPU confidential VM, and a signed **attestation report** covering GPU firmware/state that a remote party verifies against NVIDIA's attestation service before releasing work ([NVIDIA blog](https://developer.nvidia.com/blog/confidential-computing-on-h100-gpus-for-secure-and-trustworthy-ai/); [CACM: Creating the First Confidential GPUs](https://cacm.acm.org/practice/creating-the-first-confidential-gpus/)). Combined with CPU TEE attestation (AMD SEV-SNP or Intel TDX measuring the VM image), you get a verifiable claim that *a specific measured software stack loaded a specific model and ran on genuine hardware*, with only ~2–6% overhead (Blackwell figures, [GPUYard setup guide](https://www.gpuyard.com/tutorials/howto/nvidia-blackwell-confidential-computing-setup/)) or ~5–10% generally ([Equilibrium survey](https://equilibrium.co/writing/state-of-verifiable-inference)). Phala runs exactly this to sell "verifiable LLMs" through OpenRouter ([Phala blog](https://phala.com/posts/GPU-TEEs-is-Alive-on-OpenRouter)).
+
+**Caveats.** Attestation proves the *environment*, not the mathematics — you trust NVIDIA/AMD/Intel hardware and are exposed to side channels and firmware bugs (the OTR paper layers ZK spot-checks on top of TEEs precisely because of compromised-TEE risk). And critically for us: CC mode requires Hopper/Blackwell datacenter GPUs plus server platforms with SEV-SNP/TDX enabled in BIOS and the open kernel modules ([NVIDIA deployment guide](https://docs.nvidia.com/cc-deployment-guide-tdx-snp.pdf)). **No RTX consumer card supports it.** Volunteer nodes on 4060-class hardware categorically cannot provide GPU TEE attestation; Intel SGX on client CPUs is likewise not a path (deprecated on consumer parts, and it would only cover CPU-side code anyway).
+
+**Feasibility for alpha: NONE for volunteer nodes.** Roadmap option: a *TEE tier* — if datacenter H100/Blackwell operators ever join, attest them and route confidentiality-sensitive or high-value jobs there; also usable for the tracker's own reference validator.
+
+---
+
+## 2. The non-determinism problem for output comparison
+
+### 2.1 Why honest nodes disagree
+
+- **Floating-point non-associativity** is the root cause, but the *mechanism* that surfaces it is batch-variant kernels: inference servers pick different kernels/split strategies depending on batch size and load, changing reduction order and hence results — the same request returns different logits depending on what else is in the batch ([Thinking Machines: Defeating Nondeterminism in LLM Inference](https://thinkingmachines.ai/blog/defeating-nondeterminism-in-llm-inference/)).
+- **Even greedy (temperature-0) decoding diverges across configurations**: changing batch size, GPU count, GPU architecture, or tensor-parallel size measurably changes outputs under greedy decoding, and small numerical differences get **amplified autoregressively** — one flipped token early in a long generation cascades into a completely different continuation ([arXiv:2506.09501](https://arxiv.org/html/2506.09501v2); [arXiv:2511.17826](https://arxiv.org/html/2511.17826v2)).
+- Temperature > 0 sampling adds outright randomness on top unless seeds and the sampling algorithm (e.g. Gumbel-max in vLLM) are synchronized.
+
+**Consequence:** naive "re-run the prompt, compare the text" audits will flag honest heterogeneous nodes as cheaters. Never compare free-running generations token-for-token across different hardware.
+
+### 2.2 Techniques that make honest-vs-honest comparison robust
+
+1. **Teacher-forced re-verification (per-position logit/activation check) — yes, this is a recognized, state-of-the-art technique.**
+   - **TOPLOC** (Prime Intellect, ICML 2025): the prover commits top-k values/indices of the last hidden state per decode chunk (258 bytes per 32 tokens, ~1000× smaller than raw activations); the validator *re-runs the claimed token sequence as a single prefill* (teacher forcing) and checks the committed top-k against recomputed values using exponent/mantissa error thresholds. Reported: 100% detection of model, prompt, or precision substitutions with zero false positives across different GPUs, tensor-parallel layouts, and attention implementations, and validation up to **100× faster than the original inference** because prefill is compute-bound while decode is memory-bound ([TOPLOC, arXiv:2501.16007](https://arxiv.org/html/2501.16007v1); [GitHub](https://github.com/PrimeIntellect-ai/toploc)).
+   - **Token-DiFR / Activation-DiFR** (2025): synchronize the sampling seed (Gumbel-max), then compare the provider's tokens against a reference re-generation — with a shared seed, >98% of tokens match exactly for honest providers, so token divergence itself becomes the audit signal; detects 4-bit quantization with AUC > 0.999 within 300 tokens. Activation-DiFR compresses activations with random orthogonal projections and detects the same with 2 tokens. Released as a vLLM integration ([DiFR, arXiv:2511.20621](https://arxiv.org/pdf/2511.20621); [author explainer](https://technicallyprivate.substack.com/p/token-difr-llm-inference-verification)).
+   - **Log-probability auditing**: comparing per-token logprob distributions against a reference model detects even single-step fine-tuning or quantization changes; simple statistical tests (permutation test on per-token mean logprobs, KS tests) overcome logprob noise ([Logprob Tracking, arXiv:2512.03816](https://arxiv.org/html/2512.03816v1); [model-substitution audit, arXiv:2504.04715](https://arxiv.org/html/2504.04715v1)).
+2. **Tolerance-based matching, not bitwise equality.** TOPLOC accepts bounded exponent-intersection and mantissa-error deviations; DiFR scores divergence-from-reference against an honest-noise baseline. Both are explicitly designed so cross-GPU numerical noise passes while quantization/model swaps fail.
+3. **Beware scalar aggregate thresholds alone.** The DiFR authors note that a single statistic like mean cross-entropy can be gamed — a malicious provider can tune its sampling temperature until the aggregate matches expectation. Seed-synchronized token matching or per-position top-k activation checks leave far fewer degrees of freedom ([DiFR explainer](https://technicallyprivate.substack.com/p/token-difr-llm-inference-verification)).
+4. **Bitwise-deterministic kernels** (Gensyn RepOps; Thinking Machines' batch-invariant kernels; TBIK for cross-tensor-parallel invariance) make exact comparison possible but require replacing the whole operator stack and sacrifice performance — practical for a controlled verification environment, unrealistic to impose on volunteer nodes running stock llama.cpp/transformers ([Gensyn](https://blog.gensyn.ai/verde-a-verification-system-for-machine-learning-over-untrusted-nodes/); [Thinking Machines](https://thinkingmachines.ai/blog/defeating-nondeterminism-in-llm-inference/); [arXiv:2511.17826](https://arxiv.org/html/2511.17826v2)).
+
+**Practical recipe for our audits:** record prompt, claimed output tokens, sampling params, and per-hop activation fingerprints. Audit = one teacher-forced forward pass of the claimed tokens on a reference node; compare per-position: (a) hop-boundary fingerprints TOPLOC-style, and/or (b) whether each claimed token is plausible under the reference distribution (rank/logprob within tolerance; exact match if seeds are synchronized). This is cheap (single prefill), robust to hardware noise, and immune to autoregressive divergence because the token sequence is fixed.
+
+---
+
+## 3. Layer-skipping detectability
+
+**How gracefully do transformers degrade when layers are dropped?**
+
+- **Careful pruning degrades subtly.** ShortGPT removes ~25% of layers (chosen by Block Influence, training-free) and keeps ~90% of benchmark performance — e.g. LLaMA2-13B MMLU drops only 55.0→52.2 after removing 10 of 40 layers ([ShortGPT, arXiv:2403.03853](https://arxiv.org/pdf/2403.03853)). Gromov et al. find a "characteristic flat region of robust performance" on QA benchmarks followed by a **sharp collapse to random accuracy** at a model-dependent threshold: ~45–55% of layers for Llama-2 family, ~35% for Mistral-7B, ~25% for Phi-2, ~20% for Qwen — and up to ~half of Llama-2-70B's layers with healing finetuning ([The Unreasonable Ineffectiveness of the Deeper Layers, arXiv:2403.17887](https://arxiv.org/html/2403.17887v1)). LayerDrop showed a decade of precedent: networks *trained* with layer dropout can be pruned at inference with modest loss ([arXiv:1909.11556](https://arxiv.org/abs/1909.11556)).
+- **So: would skipping ~36 of 100 layers produce gibberish?** Probably not gibberish. For a Llama-like model, 36% removal of *well-chosen* layers sits below the collapse threshold — output would be degraded but often fluent, and on easy prompts might look acceptable. A lazy cheater skipping a contiguous middle block *without* choosing layers carefully does worse — Gromov et al. show the naive heuristic's loss "begins to increase very rapidly even with small amounts of pruning" before healing — but "worse" still means plausible-looking text on many prompts, not obvious garbage. **Human-eyeball or coarse quality checks are not a reliable fraud detector.**
+- **Statistical detection: yes, and easily.** Without healing, C4 validation loss rises sharply with pruning fraction (Gromov et al. Fig. 3), so perplexity of the node's outputs under a reference model shifts detectably given enough tokens. But the far stronger signal is direct: skipping any layer changes the hidden states and output logits at *every* position by amounts vastly exceeding floating-point noise. TOPLOC's evaluation explicitly includes detecting modified models with 100% accuracy; DiFR detects even 4-bit quantization (a much subtler perturbation than deleting layers) with AUC > 0.999 in ≤300 tokens. **A single teacher-forced audit pass catches layer-skipping essentially deterministically.**
+- **Pipeline nuance:** in multi-hop inference, a node that skips layers inside its assigned range corrupts its output boundary activations; the hop-boundary fingerprint comparison in §1.2 localizes exactly which node did it.
+
+---
+
+## 4. Why classic PoW does not solve verifiable useful computation
+
+- **PoW's defining property is verification asymmetry over an *arbitrary* puzzle**: work is hard to produce, trivially cheap to check (hash preimage with leading zeros), and the puzzle content is irrelevant — it exists purely to price Sybil identities and block production ([Wikipedia: Proof of work](https://en.wikipedia.org/wiki/Proof_of_work)). Useful computation generally lacks this asymmetry: checking an ML result naively requires re-executing it, which is the whole problem. This is the central, repeatedly confirmed obstacle in the Proof-of-Useful-Work literature — "the main weakness that all presented PoUW approaches have in common is the verification of results" ([Challenges of PoUW, arXiv:2209.03865](https://doi.org/10.48550/arxiv.2209.03865); [SoK: Is Proof-of-Useful-Work Really Useful?, IACR 2025/1814](https://eprint.iacr.org/2025/1814.pdf)). Expensive verification then triggers the **verifier's dilemma**: rational verifiers skip checking, and security collapses ([Truebit whitepaper §1](http://people.cs.uchicago.edu/~teutsch/papers/truebit.pdf)).
+- **Live case study:** io.net's hourly "Proof-of-Work" makes GPUs solve hash puzzles and proves *the hardware exists, has the claimed VRAM, and is online* ([io.net PoW docs](https://io.net/docs/guides/workers/proof-of-work)). It was bolted on after the April 2024 Sybil attack (~1.8M fake GPUs spoofed via a shared auth token to farm airdrops) and says nothing about whether any customer job was computed correctly ([io.net 2026 analysis](https://cryptoaianalysis.com/io-net-io-analysis-2026/)). PoW = admission control and capacity attestation; correctness needs a separate mechanism.
+- **Self-computed checksums/commitments: confirmed — no standalone correctness guarantee.** A hash or Merkle commitment over activations is *binding* (the node can't later change its story) and possibly *hiding*, but the committed values are whatever the node computed — a malicious node honestly commits to its dishonest activations, and the checksum verifies perfectly. Correctness only enters when an independent party recomputes and compares against the commitment. That is precisely how the serious systems use commitments: Truebit's Merkle state roots and Verde's checkpoint hashes exist to make **dispute bisection** possible and to **pin claims before an unpredictable audit** (so a node can't retroactively fix its answer once it learns it's being checked), never as proof by themselves ([Truebit](http://people.cs.uchicago.edu/~teutsch/papers/truebit.pdf); [Verde, arXiv:2502.19405](https://arxiv.org/html/2502.19405v1); TOPLOC commitments are verified by validator recomputation — [arXiv:2501.16007](https://arxiv.org/html/2501.16007v1)).

+
+## 5. What comparable networks actually do
+
+| Network | Verification of outputs | Sybil / fraud handling | Notes |
+|---|---|---|---|
+| **Prime Intellect** | TOPLOC activation commitments per sequence; validators teacher-force-recompute (sampled, up to 100× faster than generation); plus sampling-sanity and data-sanity checks | Invalid batches → node **slashed and evicted** from compute pool; hardware checks at registration | Deployed at scale for INTELLECT-2 (32B RL run over permissionless nodes) ([arXiv:2505.07291](https://arxiv.org/html/2505.07291)) |
+| **Gensyn** | Verde refereed delegation: bisect disputes to a single operator; referee recomputes it; requires RepOps bitwise-reproducible kernels | Correct result guaranteed if ≥1 of the assigned providers is honest; economic penalties on losers of disputes | The most rigorous trustless design; reproducibility stack is the price ([Verde](https://arxiv.org/html/2502.19405v1); [docs](https://docs.gensyn.ai/core-components)) |
+| **Bittensor** | No direct output verification: subnet **validators score miners**; Yuma Consensus aggregates stake-weighted scores into emissions | Registration costs + stake; the notorious **weight-copying** problem (validators free-riding by copying consensus weights) countered by Commit-Reveal v3: timelock-encrypted weights revealed epochs later so copiers only get stale data ([weight copying](https://docs.learnbittensor.org/concepts/weight-copying-in-bittensor); [commit-reveal](https://docs.learnbittensor.org/concepts/commit-reveal)) | Verification quality is per-subnet and heuristic; consensus rewards conformity, not proven correctness |
+| **io.net** | None for job outputs | Hourly hash-puzzle PoW + VRAM check + Proof of Time-Lock (uptime), added after the Apr 2024 fake-GPU Sybil attack; failed checks → excluded from rewards/hiring ([PoW docs](https://io.net/docs/guides/workers/proof-of-work); [Messari overview](https://messari.io/report/understanding-io-net-a-comprehensive-overview)) | Marketplace model: hardware attestation only, correctness left to the customer |
+| **Ritual (Infernet)** | Modular: nodes may attach ZK, optimistic, or TEE proofs; consumer contracts opt in ([Ritual blog](https://ritual.net/blog/celestia)) | ChainLight's security review: base Infernet has **no aggregation of multiple nodes, no reputation, no penalty for malicious nodes returning wrong results** ([ChainLight](https://blog.chainlight.io/ecosystem-explorer-exploring-security-risks-in-ai-blockchain-projects-2c490a726d13)) | "Verification-optional" in practice |
+| **Hyperbolic** | PoSP/spML: random spot-check by a second node; disagreement → arbitration; slashing of the dishonest party ([PoSP, arXiv:2405.00295](https://arxiv.org/html/2405.00295)) | Nash-equilibrium argument that rational nodes stay honest; validator anonymity until finalization to resist collusion | Closest published formalization of our intended scheme |
+| **Akash** | None (general compute marketplace) | **Auditor-attested provider tiers**: governance-approved auditors post on-chain attestations; no provider staking/slashing — ChainLight flags malicious-provider risk as an accepted gap ([ChainLight](https://blog.chainlight.io/ecosystem-explorer-exploring-security-risks-in-ai-blockchain-projects-2c490a726d13); [Akash docs](https://akash.network/docs/providers/getting-started/should-i-run-a-provider/)) | Reputation = audit badge + market history |
+| **Petals** (closest architectural cousin: volunteer, pipeline-parallel, consumer GPUs) | **None** — the paper and docs openly state malicious peers can alter outputs; mitigation is "use a private swarm of people you trust"; devs planned a centralized points system for nodes that "consistently return correct results" ([GitHub](http://github.com/bigscience-workshop/petals); [dev comments on HN](https://news.ycombinator.com/item?id=34215665)) | Proof that the architecture works, and that the fraud layer is the missing piece we're building |
+| **Together AI** | Centralized provider; no public trustless verification protocol — trust is contractual/reputational | n/a | Included for contrast: the "trusted provider" baseline |
+| **Atoma / Ambient** (emerging) | Atoma: TEE where available, else user-configurable redundant sampling; Ambient: "Proof of Logits" fingerprinting with ~0.1% claimed overhead but no open implementation ([Equilibrium survey](https://equilibrium.co/writing/state-of-verifiable-inference)) | — | Signal of where the field is converging: logit fingerprints + sampling |
+
+**Pattern:** nobody in production uses zkML for LLM serving; nobody offers TEE on consumer GPUs; every serious inference-verification deployment converges on *commit → sampled teacher-forced recompute → slash/reputation*, with refereed delegation as the trustless escalation path.
+
+---
+
+## 6. Reputation systems for routing and audit-rate weighting
+
+**Foundations.** EigenTrust computes global trust as the principal eigenvector of normalized local trust ratings and remains the canonical design; in simulation it suppresses malicious collectives up to large fractions of the network, but it depends on pre-trusted peers and majority-honest aggregation ([EigenTrust, WWW'03](https://nlp.stanford.edu/pubs/eigentrust.pdf)).
+
+**Documented pitfalls** (from EigenTrust's own threat models and the P2P reputation-attack literature — [survey](https://cnitarot.github.io/papers/p2p-reputation-survey.pdf)):
+
+- **Sybil flooding / whitewashing:** free identities let attackers dominate the "unknown newcomer" pool and shed bad reputations by rejoining. Defense: entry cost (stake, invite, proof-of-hardware), newcomer probation with low routing weight and *elevated* audit rates.
+- **Reputation farming / milking:** behave honestly on cheap jobs to build score, then cash in on expensive ones ("moles" that interleave honest work are documented in real systems like Maze). Defense: value-weighted reputation (a job's reputation contribution ∝ its audited value), and audit probability that never floors at zero for anyone.
+- **Collusion rings:** peers mutually inflating ratings. Defense: in our alpha, reputation should derive **only from tracker-verified audit outcomes**, never from peer ratings — this deletes the collusion surface EigenTrust suffers from. (EigenTrust++ hardens propagation with feedback-similarity for when peer ratings do get introduced — [EigenTrust++](https://doi.org/10.4108/icst.collaboratecom.2012.250420).)
+- **Weight-copying (Bittensor's lesson):** any published evaluation signal will be free-ridden by lazy evaluators; the fix is delaying/encrypting evaluations (commit-reveal timelock) until they're stale ([Bittensor docs](https://docs.learnbittensor.org/concepts/weight-copying-in-bittensor)). Relevant to us only when third-party validators exist; a single tracker has no one to copy from.
+
+**Reputation-weighted routing + audit rates in practice.** io.net gates hiring and block rewards on rolling verification status; Akash routes via audit-tier filters; Bittensor routes emissions via consensus-weighted scores. The clean design for us, consistent with PoSP-style deterrence:
+
+- **Routing weight** increases with reputation (and observed TPS, already tracked), so honest nodes earn more — making L (loss-on-catch, §1.1) grow with tenure.
+- **Audit rate** decreases with reputation but has a hard floor (e.g. new node 20–30% → veteran 2–3%, floor ≥ 2%), keeping the overall budget ≈ 5% while making cheating-as-a-newcomer maximally risky and reputation-then-defect still irrational.
+- **Asymmetric dynamics:** slow to build, instant to lose (existing 3-strike forfeiture design already matches this), plus decay on inactivity so parked identities can't hoard trust.
+- **Unpredictability is load-bearing:** audit selection must be indistinguishable from normal traffic at request time (same request format, decided by tracker RNG/VRF after commitment), or nodes cheat only on non-audited requests — the exact property both PoSP and INTELLECT-2 rely on.
+
+---
+
+## 7. Feasibility table for the neuron-tai alpha
+
+Alpha constraints: volunteer 8 GB consumer GPUs, single trusted tracker, mock-USDT but real carried-forward reputation, ~5% audit budget, small models today (0.5B-class) scaling up.
+
+| Technique | Alpha feasibility | Overhead | What it buys | Verdict |
+|---|---|---|---|---|
+| Optimistic accept + random teacher-forced audit (~5%) | **High** — tracker (or a trusted validator node) re-runs claimed tokens as one prefill | ~5% of serving compute; audits themselves up to ~100× cheaper than original generation | Detects wrong model, quantization, layer-skipping, garbage outputs; rational-cheating deterrence at L > 19× per-job gain | **Do now (anchor)** |
+| Per-hop activation fingerprints (TOPLOC-style top-k, tolerance matching) | **High** — few hundred bytes per response per hop; nodes already stream activations | Negligible at inference; storage ~258 B/32 tokens/hop | Pins claims before audit; localizes blame to the exact hop on audit failure | **Do now** |
+| Hop-boundary replay "bisection" (referee = tracker, non-interactive) | **Medium-high** — needs a reference node able to run the full model or per-hop ranges | Only on audit failure / dispute | Culprit identification in multi-hop pipelines; fair slashing | **Do now (simplified form)** |
+| Seed-synchronized sampling (Token-DiFR-style exact-token audits) | **Medium** — requires controlling the sampler (Gumbel-max w/ shared seed) in node runtime | Zero at serve time | Strongest per-token evidence; >98% exact match for honest nodes | **Do if node runtime is ours; else logprob-rank tolerance** |
+| Statistical logprob/perplexity monitoring (passive, on all traffic) | **High** — reference-free heuristics (output perplexity, repetition, truncation) + periodic logprob tests | Tiny | Cheap tripwire that raises a node's audit rate when outputs look off | **Do now (cheap complement)** |
+| Reputation-weighted routing + reputation-weighted audit rate with floor | **High** — extends existing tracker reputation/strikes | None | Makes deterrence math work; concentrates audits on new/suspect nodes | **Do now** |
+| Full interactive verification game (Truebit/Verde) with bitwise RepOps kernels | Low — requires replacing node operator stacks, decentralized referees | High engineering; runtime penalty for reproducible kernels | Trustless dispute resolution without a trusted tracker | **Roadmap (multi-tracker era)** |
+| zkML proofs of inference | None — GPT-2-scale, tens of seconds per proof, server-class hardware ([zkGPT](https://www.usenix.org/conference/usenixsecurity25/presentation/qu-zkgpt); [NanoZK](https://arxiv.org/html/2603.18046v1)) | 100–10,000× | Cryptographic soundness | **Roadmap-only; re-evaluate yearly** |
+| GPU TEE attestation | None on consumer cards (H100/Blackwell + SEV-SNP/TDX servers only — [NVIDIA guide](https://docs.nvidia.com/cc-deployment-guide-tdx-snp.pdf)) | ~2–10% where available | Hardware-rooted "right model+code ran" | **Roadmap: optional attested tier for datacenter contributors** |
+| PoW-style hardware challenges (io.net-like) | Medium — trivial to add | Idle-time only | Sybil/VRAM/capacity attestation at registration; NOT output correctness | **Optional, registration-time only; don't confuse with fraud layer** |
+
+---
+
+## 8. Recommended layered scheme for alpha
+
+1. **Commit layer (on-demand, audit-selected):** when a request is selected for audit, each hop signs and reports a TOPLOC-style top-k fingerprint of its output boundary activations plus the sampling metadata (params, seed if controlled). Client-visible response carries the full claimed token sequence. Commitments are cheap and make retroactive lying impossible — they are *audit pins, not proofs* (§4).[^alpha-on-demand]
+
+[^alpha-on-demand]: Alpha implements **on-demand** commitments per [ADR-0018 §3](../../docs/adr/0018-fraud-detection-verification-and-reputation.md) — not every request. Nodes retain recent activations briefly; serving path stays uncommitted until audit selection.
+2. **Audit layer (~5% of requests, VRF/tracker-RNG selected, indistinguishable ex ante):** a reference executor teacher-forces the claimed tokens in one prefill and checks (a) per-position token plausibility under the reference distribution (exact match if seed-synced; logprob-rank tolerance otherwise) and (b) hop-boundary fingerprints within TOPLOC-style exponent/mantissa tolerances. New/low-reputation nodes get 20–30% audit rates, veterans 2–3%, floor ≥ 2%, budget-balanced to ≈5% overall.
+3. **Blame layer (on audit failure):** replay comparison across hop cut-points identifies the first divergent hop; that node eats the penalty (forfeit pending balance + strike, per the existing forfeiture design), and its audit rate snaps to maximum. Honest-noise false positives are handled by tolerance calibration against an honest-node baseline corpus (collect this first — run identical jobs across the current node fleet to measure the honest divergence envelope before setting thresholds).
+4. **Reputation layer:** reputation derives exclusively from audit outcomes + uptime/latency, never peer ratings (no collusion surface). It weights routing (earnings) and inversely weights audit probability. Slow build, instant loss, decay on inactivity, entry probation for Sybil/whitewash resistance.
+5. **Tripwire layer (all traffic, passive):** perplexity/repetition/truncation anomaly scoring on outputs; anomalies don't punish directly, they escalate the node's audit rate.
+
+This is, deliberately, the Prime Intellect / Hyperbolic pattern adapted to multi-hop pipelines with the tracker as referee — every component has a deployed or peer-reviewed precedent.
+
+## 9. Explicitly NOT feasible for alpha (roadmap-only)
+
+- **zkML proofs of LLM inference** — 3+ orders of magnitude too slow for multi-billion-parameter serving; provers won't run on 8 GB cards. Revisit if layerwise/GKR provers (NanoZK, zkGPT lineage) reach real-time on 7B+ models.
+- **GPU TEE / confidential-computing attestation on volunteer nodes** — hardware doesn't exist on consumer GPUs. Keep as an *attested datacenter tier* concept.
+- **Fully trustless interactive verification games** (Truebit/Verde with on-chain referees and bitwise-reproducible kernels) — pointless while a single trusted tracker exists; becomes the correct escalation path when trackers decentralize. Requires shipping a reproducible-operator runtime to nodes.
+- **Decentralized third-party verifier markets** (and their incentive pathologies: verifier's dilemma, forced-error jackpots, Truebit's 500–5000% verification tax) — single-tracker alpha sidesteps all of it; re-enters with multi-tracker.
+- **Peer-rating reputation (EigenTrust-style transitive trust)** — collusion/Sybil surface with no benefit while the tracker is the sole verifier.
+- **Commit-reveal timelock machinery for evaluator honesty** (Bittensor CRV3) — solves weight-copying among many validators; irrelevant until independent validators exist.
+- **PoW puzzles as a correctness mechanism** — category error (§4); acceptable only as optional registration-time hardware attestation.

+## Open-source reusability & build-vs-adopt
+
+**Added 2026-07-04.** Focused follow-up: which of the projects above ship code we can actually reuse, and is verified decentralized inference a "solved problem"? All repo facts below checked against the GitHub repos/APIs on 2026-07-04.
+
+### TOPLOC (Prime Intellect) — a real, adoptable library
+
+- **Repo & license:** [PrimeIntellect-ai/toploc](https://github.com/PrimeIntellect-ai/toploc), **MIT** (both the repo license and the `pyproject.toml` declaration). Published on PyPI as `pip install toploc`. Separate [toploc-experiments](https://github.com/PrimeIntellect-ai/toploc-experiments) repo holds the paper's vLLM-integrated experiment code.
+- **Maintenance:** actively maintained — created 2025-01-28, last push **2026-07-02** (two days before this writing), 56 stars / 12 forks / 12 open issues. Small single-purpose codebase (Python + a compiled extension; ships wheels, depends only on `torch`/`numpy`).
+- **What it actually is:** a *library*, not a framework. Two function families ([README](https://github.com/PrimeIntellect-ai/toploc)):
+  - `build_proofs_bytes/base64(activations, decode_batching_size, topk, skip_prefill)` — prover side: takes a list of activation tensors (prefill tensor + one last-hidden-state tensor per generated token, bf16 in the examples) and returns compact proofs (~10 bytes each; 258 bytes per 32 tokens per the paper).
+  - `verify_proofs_bytes/base64(recomputed_activations, proofs, ...)` — verifier side: returns per-chunk `VerificationResult(exp_intersections, mant_err_mean, mant_err_median)`; **the accept/reject thresholds are ours to set and calibrate** (the paper gives reference thresholds validated across GPU types).
+- **Assumptions:** model- and runtime-agnostic — it operates on tensors you extract yourself. It does *not* hook into vLLM/transformers for you; capturing the last hidden state per decode step in the node runtime, and recomputing activations via teacher-forced prefill on the validator, is our integration work. Detects precision changes by design, so **we must pin one canonical precision/quantization per served model** or honest quantized volunteers will fail verification.
+- **Integration estimate for our pipeline-parallel case:** modest. (1) Node runtime: capture final-hidden-state per token, call `build_proofs_*`, attach to response — days, not weeks. (2) Tracker/validator: teacher-forced prefill re-run + `verify_proofs_*` — days. (3) The genuinely new part is *per-hop* commitments: TOPLOC as published commits only the **final** hidden state (whole-pipeline check, catches that fraud happened); applying the same encoding to hop-boundary activations for per-node blame is our own straightforward extension since the functions are tensor-generic, but its thresholds across heterogeneous 8 GB cards must be calibrated by us — that empirical honest-noise calibration is the real work. (4) Threshold calibration corpus across the volunteer fleet — the long pole, but required for any tolerance-based scheme regardless of library.
+
+### Gensyn — papers and proprietary binaries, not a reusable verification library
+
+What is actually public in [github.com/gensyn-ai](https://github.com/gensyn-ai) (org listing checked 2026-07-04):
+
+- **[rl-swarm](https://github.com/gensyn-ai/rl-swarm)** — MIT, 1.7k stars: a framework for *RL training swarms*, plus [rl-swarm-contracts](https://github.com/gensyn-ai/rl-swarm-contracts) (coordination contracts). Not inference verification; not relevant to our fraud layer.
+- **Verde (dispute resolution): paper only.** No `verde` repository exists in the org. The bisection/arbitration protocol from [arXiv:2502.19405](https://arxiv.org/html/2502.19405v1) has no published implementation. If we want it, we implement it from the paper.
+- **RepOps / reproducible execution: shipping, but proprietary.** [repops-demo](https://github.com/gensyn-ai/repops-demo) is demo scripts with **no OSS license file** (only a `LICENSE-LLAMA` for the model weights) driving a prebuilt Docker image; supported targets include consumer RTX 3090/4070/4090 (CC 7.5–9, CUDA 12.6+). The successor [ree](https://github.com/gensyn-ai/ree) (Reproducible Execution Environment) is explicit in its README: the SDK wrapper is MIT, but **"the REE compiler binary and the REE reproducible-operators binary … are not licensed under the MIT License"** — they fall under a proprietary REE Binary License. REE does reproducible *LLM inference* with run/verify receipts, pipeline parallelism up to 72B (v0.2.0 notes), and needs Docker + NVIDIA driver ≥570. So bitwise cross-GPU determinism is real and demonstrably achievable on consumer GPUs — but as a closed-source appliance, not an embeddable library.
+- **"Judge"** (verifiable AI evaluator, [docs](https://docs.gensyn.ai/core-components)) — no public library repo found in the org.
+- **Assessment of the RepOps requirement:** deterministic cross-GPU execution means reimplementing/fixing the reduction order of every operator (matmul, attention, norms) for every hardware target — a compiler/kernel-engineering effort Gensyn keeps proprietary, and Thinking Machines' open batch-invariant kernels ([blog](https://thinkingmachines.ai/blog/defeating-nondeterminism-in-llm-inference/)) only address batch-invariance on one platform, not cross-GPU bitwise equality. **This is a large lift with no off-the-shelf OSS solution; it is exactly what TOPLOC-style tolerance matching lets us avoid.** Adopting REE would mean forcing volunteers into Gensyn's Docker appliance (proprietary binaries, driver floor, perf overhead) — a non-starter for our alpha; a possible future option for the *validator/referee* environment only.
+
+### Bittensor — an incentive market, not verification code (confirmed)
+
+- **Confirmed from primary sources:** the [whitepaper](https://bittensor.com/whitepaper) frames Bittensor as peers ranking peers ("intelligence measured by intelligence"), and the [Yuma Consensus docs](https://docs.learnbittensor.org/yuma-consensus) describe the on-chain mechanism precisely: each subnet validator submits a **weight vector ranking miners**; YC resolves the stake-weighted matrix into emissions, **clipping** any weight above the level supported by κ (default 0.5) of stake to punish out-of-consensus/collusive over-evaluation, and paying validators via EMA **bonds** that reward staying near consensus. There is **no cryptographic verification of any computation anywhere in the mechanism** — correctness of miner outputs is whatever each subnet's own validator code decides to score. The chain ([opentensor/subtensor](https://github.com/opentensor/subtensor), Rust, The Unlicense, actively developed) implements the consensus/emissions math, not inference checking.
+- **What subnets actually do:** subnet owners write off-chain validator logic (Python, typically on the MIT-licensed [bittensor SDK](https://github.com/opentensor/bittensor)) that queries miners with tasks and scores responses — reference-model comparison, heuristics, or LLM-judging, entirely subnet-specific. Quality of validation is therefore uneven by construction.
+- **Known weaknesses & mitigations (documented by Bittensor itself):** validator **weight-copying** (free-riding on the public weight matrix) — mitigated by Commit-Reveal v3 timelock-encrypted weights revealed epochs later ([weight copying](https://docs.learnbittensor.org/concepts/weight-copying-in-bittensor); [commit reveal](https://docs.learnbittensor.org/concepts/commit-reveal)); lazy/colluding validators — mitigated only economically via clipping and bond penalties; and the docs concede commit-reveal fails if miner rankings are too static.
+- **Reusable for us:** the *design patterns* — stake-weighted score aggregation with clipping, EMA-smoothed trust, commit-reveal for future multi-validator honesty — not code. Subtensor's Rust consensus math is chain-embedded and solves a multi-validator problem we don't have while the single tracker is the only scorer.
+
+### Other OSS in this niche
+
+- **EZKL** ([zkonduit/ezkl](https://github.com/zkonduit/ezkl)) — **real, mature library** (Rust with Python/JS bindings, **Apache-2.0** per its [npm package](https://registry.npmjs.org/ezkl) and README, ~1.2k stars, last push 2026-02). It proves ONNX-graph inference in ZK and genuinely works — for *small* models (MLPs, small CNNs/regressors; §1.3 overheads apply). Irrelevant to serving multi-billion-parameter LLMs, but adoptable later if we ever need to prove a tiny model (e.g., a routing/scoring model) on-chain.
+- **Petals** ([bigscience-workshop/petals](https://github.com/bigscience-workshop/petals)) — MIT, 10.3k stars, but **effectively dormant (last push Sep 2024)** and contains **zero trust machinery**: its own docs say malicious peers can alter outputs and recommend private swarms (§5). Its `hivemind` DHT/networking stack (MIT, also mirrored by Gensyn) is reusable *infrastructure*, not verification. Petals is validation of our architecture and a warning, not a component.
+- **Hyperbolic PoSP/spML** — **paper + marketing only**. The [HyperbolicLabs GitHub org](https://github.com/HyperbolicLabs) contains agent kits, MCP servers, and a k8s OS — no PoSP/spML implementation is published. Adapt the pattern from [arXiv:2405.00295](https://arxiv.org/html/2405.00295); there is nothing to adopt.
+- **Ritual Infernet** — the node ([ritual-net/infernet-node](https://github.com/ritual-net/infernet-node), Python, BSD-3-Clause-Clear per its community port; direct repo access was flaky at check time) plus [infernet-deploy](https://github.com/ritual-net/infernet-deploy)/[infernet-sdk](https://github.com/ritual-net/infernet-sdk) are open **coordination/oracle plumbing** (request routing, container orchestration, on-chain delivery). Proofs are a pluggable slot, not shipped verification logic, and ChainLight's review found no output aggregation, reputation, or penalties in the base system (§5). Nothing here advances our fraud layer.
+- **DiFR** — the Token/Activation-DiFR authors state they released an **open-source vLLM integration** ([arXiv:2511.20621](https://arxiv.org/pdf/2511.20621)); worth tracking as a second adoptable audit primitive alongside TOPLOC, especially the seed-synchronized exact-token variant.
+
+### Bottom line: is it solved?
+
+**The audit primitive is solved and adoptable; the system around it is not.** No OSS project ships an end-to-end "verified decentralized inference network in a box" — every network either built theirs in-house (Prime Intellect), kept the hard part proprietary (Gensyn REE binaries), or doesn't verify at all (Petals, Akash, base Infernet, Bittensor's chain). What *is* genuinely reusable is small, high-quality, and MIT-licensed: TOPLOC. Everything else we need is a pattern to adapt or thin logic to build on our tracker, which is appropriately bespoke (it's our economics).
+
+| Capability | Verdict | Component / reference | Rationale |
+|---|---|---|---|
+| **Detection / audit** (teacher-forced re-verification) | **ADOPT** | [`toploc`](https://github.com/PrimeIntellect-ai/toploc) (MIT, PyPI, maintained) — track [DiFR's vLLM integration](https://arxiv.org/pdf/2511.20621) as a complement | Proven encoding + verifier with cross-GPU tolerance semantics; our work is runtime hooks + threshold calibration, not algorithm development |
+| **Blame attribution / bisection** (per-hop) | **ADAPT + BUILD** | Verde's commit-then-recompute pattern ([arXiv:2502.19405](https://arxiv.org/html/2502.19405v1)); reuse TOPLOC's encoding on hop-boundary activations | No published Verde code; full bisection is overkill for a handful of hops — a single referee replay over committed hop boundaries suffices (§1.2) |
+| **Reputation / incentive** | **ADAPT + BUILD** | PoSP deterrence math ([arXiv:2405.00295](https://arxiv.org/html/2405.00295)); Yuma patterns (clipping, EMA trust, [commit-reveal](https://docs.learnbittensor.org/concepts/commit-reveal)) for the future multi-validator era; EigenTrust pitfalls list (§6) | No code to adopt (PoSP unpublished; Yuma is chain-embedded Rust for a different topology); our tracker-side logic is small and economics-specific |
+| **Cryptographic proof** (zkML / TEE / bitwise-reproducible execution) | **NEITHER (roadmap)** | EZKL (Apache-2.0) if a tiny provable model ever needs it; Gensyn REE as a proprietary-appliance option for a future referee tier; GPU TEE per §1.4 | All three are unusable on 8 GB volunteer cards today (§1.3–1.4); REE's reproducible operators are closed-source binaries |
+
+**Direct answer to the owner:** Gensyn and Bittensor are the right things to read but the wrong things to build on — Gensyn's verification core is a paper plus proprietary binaries aimed at training-grade trustlessness we don't need under a single trusted tracker, and Bittensor ships an incentive market that deliberately contains no computation verification at all. The one shelf-ready piece for our exact audit step is TOPLOC (MIT, pip-installable, updated this week), and the recommended alpha scheme in §8 remains: adopt TOPLOC for the audit primitive, adapt PoSP/Verde patterns for deterrence and blame, and build the thin tracker-side reputation/audit-rate logic ourselves.

+# Runbook: Ledger backup
+
+Covers backing up the tracker's authoritative money/trust state — the billing
+ledger, dashboard accounts DB, and node registry (strike/ban/reputation) — and
+how to pause hive gossip during the backup window so peers don't replicate
+against a half-copied file.
+
+## Trust assumptions (read first)
+
+Per [ADR-0016](../../../docs/adr/0016-alpha-scope-and-known-limitations.md), one
+operator-designated tracker holds the treasury keypair and is the source of
+truth for settlement; other hive members only replicate. Back up **that**
+tracker's databases — a follower's copies are eventually consistent, not
+authoritative. See [ADR-0015](../../../docs/adr/0015-usdt-custodial-settlement.md)
+for the settlement loop these tables feed.
+
+## Prerequisites
+
+- Shell access to the settlement-capable tracker host.
+- `sqlite3` CLI (or `.backup` support in the Python `sqlite3` module) available
+  for online, consistent snapshots.
+- Know the tracker's configured DB paths — defaults, unless overridden by CLI
+  flags:
+  - Billing ledger: `billing.sqlite` (`--billing-db`, `DEFAULT_BILLING_DB_PATH`
+    in `packages/tracker/meshnet_tracker/billing.py`)
+  - Dashboard accounts: `accounts.sqlite` (`--accounts-db`,
+    `DEFAULT_ACCOUNTS_DB_PATH` in `packages/tracker/meshnet_tracker/accounts.py`)
+  - Node registry (strike/ban/reputation event log,
+    `packages/contracts/meshnet_contracts/__init__.py::RegistryEventLog`): path
+    is whatever was passed as `registry_db` when the tracker's
+    `LocalSolanaContracts` was constructed. **As of this writing the tracker
+    CLI (`meshnet_tracker/cli.py`) does not expose a `--registry-db` flag or
+    wire a `contracts=` instance into `TrackerServer` by default** — confirm
+    with whoever deployed this tracker whether registry persistence is
+    actually enabled before assuming a file exists to back up. If it isn't
+    wired up yet, strike/ban/reputation state is RAM-only and this step is
+    moot until that gap closes (tracked loosely against issue 05).
+
+## Steps
+
+1. Identify the actual DB paths in use (check the tracker's start command /
+   systemd unit / process env for `--billing-db`, `--accounts-db`, and any
+   registry DB argument).
+2. **Pause hive gossip** on this tracker so peers don't pull a partial/locked
+   file mid-backup:
+   - If the tracker is the sole settlement node with no `--cluster-peers`,
+     gossip is already off — skip to step 3.
+   - Otherwise, stop replication by restarting the process without
+     `--cluster-peers` (or with an empty peer list) for the duration of the
+     backup, or take the backup during a maintenance window with peers
+     temporarily pointed away from this tracker at the load balancer/DNS
+     level. There is currently no live "pause gossip" admin endpoint — this is
+     a process-restart-level operation.
+   - Confirm no in-flight `/v1/registry/gossip`, `/v1/billing/gossip`, or
+     `/v1/accounts/gossip` traffic before proceeding (check access logs).
+3. Take an online, consistent copy of each SQLite file using the backup API
+   rather than `cp` (WAL-mode files can be mid-write):
+   ```
+   sqlite3 billing.sqlite ".backup '/backups/billing-$(date +%Y%m%dT%H%M%S).sqlite'"
+   sqlite3 accounts.sqlite ".backup '/backups/accounts-$(date +%Y%m%dT%H%M%S).sqlite'"
+   # registry DB, if configured:
+   sqlite3 registry.sqlite ".backup '/backups/registry-$(date +%Y%m%dT%H%M%S).sqlite'"
+   ```
+4. Verify each backup opens and has rows in its expected tables
+   (`billing_ledger`/event log tables, `accounts`, `registry_events`).
+5. Resume gossip (restore `--cluster-peers` / routing) once backups are
+   confirmed good.
+6. Ship backups off-host per your normal retention policy. Do not store them
+   alongside `.env.devnet` or keypair files (see secrets handling below).
+
+## Rollback
+
+- If a restore is needed, stop the tracker, replace the live `.sqlite` file(s)
+  with the chosen backup, and restart. Because billing/accounts/registry each
+  use append-only event logs, a stale restore under-counts recent activity
+  rather than corrupting state — reconcile any gap against node/operator
+  reports for the missing window before resuming payouts.
+- If gossip was paused via a peer-list restart, confirm peers re-sync
+  (`events_since` catch-up) before considering the rollback complete.
+
+## Secrets handling
+
+- Never commit `.env.devnet`, treasury keypair JSON files, `--hive-secret`, or
+  `--validator-service-token` values to a repo or ship them inside a DB backup
+  archive. Back these up separately, encrypted, per your existing secrets
+  process.

+# Runbook: Treasury key rotation (devnet mock-USDT)
+
+Covers rotating the devnet treasury keypair and/or the mock-USDT mint without
+double-crediting client ledger balances or double-paying nodes.
+
+## Trust assumptions (read first)
+
+Per [ADR-0015](../../../docs/adr/0015-usdt-custodial-settlement.md), a single
+project-owned wallet custodies all funds; the treasury keypair is loaded only
+on the operator-designated settlement tracker (ADR-0016 §1). Rotating this key
+is a trusted-operator action — there is no on-chain multisig or trustless
+handoff in the alpha design. Devnet uses a self-created mock-USDT SPL mint
+(6 decimals); real USDT only exists on mainnet, so this procedure is
+devnet-only until a mainnet cutover ADR supersedes it.
+
+## Prerequisites
+
+- Access to `scripts/devnet_setup.py` and its dependencies (`solders`,
+  `meshnet_contracts.solana_adapter.SolanaCustodialTreasury`).
+- The current treasury keypair path (default
+  `~/.config/solana/meshnet-treasury.json`, or whatever `--treasury-keypair`
+  the running tracker uses) and current `MESHNET_USDT_MINT` /
+  `MESHNET_TREASURY_WALLET` values (see `.env.devnet`, never committed).
+- Ability to stop/restart the settlement-capable tracker.
+- Confirm the deposit watcher's dedupe state (transaction signatures already
+  credited) is durable — it must survive the rotation so replayed/rescanned
+  transfers under the *old* wallet don't get re-credited under the *new* one.
+
+## Two rotation scenarios
+
+### A. Rotate the treasury keypair only (same mint, same on-chain wallet funds move)
+
+The treasury wallet address changes because it's derived from the keypair, so
+this requires migrating funds, not just swapping a file.
+
+1. Generate a new keypair (do **not** reuse `_load_or_create_keypair` against
+   the old path — write to a new path so both keys exist during the
+   transition):
+   ```
+   python scripts/devnet_setup.py --keypair ~/.config/solana/meshnet-treasury-new.json \
+     --mint <EXISTING_MOCK_USDT_MINT> --env-out .env.devnet.new
+   ```
+   This creates the new treasury wallet + token account and reuses the
+   existing mint (no new token, so client balances denominated in that mint
+   are unaffected).
+2. Drain the old treasury token account to the new one via a single SPL
+   transfer sized to the *entire current balance* (record the exact amount
+   and the source tx signature before moving anything).
+3. **Freeze settlement during the drain**: stop the settlement-capable
+   tracker (or restart it with no `--treasury-keypair` so the settlement loop
+   is inert) before step 2, so no payout is in flight against the old wallet
+   while funds move.
+4. Update the tracker's `--treasury-keypair`, `--treasury-wallet`-derived
+   config (i.e. the new `.env.devnet`) and restart the tracker pointed at the
+   new keypair.
+5. Verify: `treasury.get_sol_balance()` / mock-USDT balance on the new wallet
+   matches the old wallet's pre-drain balance; old wallet balance is zero.
+6. Only after verification, revoke/delete the old keypair file.
+
+### B. Rotate the mock-USDT mint (e.g. compromised or mis-configured mint)
+
+This is a bigger change — it invalidates every client's existing off-chain
+ledger balance denomination reference and any node's pending on-chain payout
+expectations. Treat as a deliberate migration, not a routine rotation:
+
+1. Settle (pay out) all pending node balances against the *old* mint before
+   cutover — the pending-balance forfeiture/collateral model (ADR-0015)
+   assumes pending balances are payable in a known mint.
+2. Create the new mint and treasury token account:
+   ```
+   python scripts/devnet_setup.py --keypair <treasury-keypair> --env-out .env.devnet
+   ```
+   (omit `--mint` so a fresh mint is created).
+3. Update tracker config (`MESHNET_USDT_MINT`) and restart.
+4. Re-mint/airdrop mock USDT to active client wallets under the new mint as
+   needed (`--mint-to`), since off-chain ledger balances are *not*
+   automatically re-denominated — this is a devnet convenience step, not a
+   guarantee that would hold for real USDT.
+
+## Avoiding double-credit
+
+The deposit watcher (issue 32) dedupes by on-chain transaction signature. The
+signature space for the old and new treasury token accounts/mints is
+disjoint, so:
+
+- Do not replay old-wallet deposit history against the new wallet's watcher —
+  it has no record of those signatures and would (correctly) not credit them,
+  but any manual "catch-up crediting" script must not re-process transfers the
+  old watcher already credited. Cross-check the old ledger's credited-tx-sig
+  table before any manual reconciliation entry.
+- Keep the old watcher's dedupe DB/table around (don't drop it as part of
+  rotation) until you've confirmed no in-flight deposits to the old address
+  remain unconfirmed.
+
+## Rollback
+
+- Scenario A: if the new wallet fails verification, restart the tracker with
+  the old `--treasury-keypair` — no client-facing state changed since ledger
+  balances are keyed by API key, not treasury wallet address.
+- Scenario B: if re-minting under the new mint goes wrong, restart the
+  tracker against the old `MESHNET_USDT_MINT` config; nothing was destroyed on
+  the old mint.
+
+## Secrets handling
+
+- Never commit `.env.devnet`, `.env.devnet.new`, or any `*treasury*.json`
+  keypair file. `scripts/devnet_setup.py` writes keypairs with `0o600`
+  permissions — preserve that when copying.
+- Treat the treasury keypair as the single highest-value secret in this
+  system per ADR-0015/ADR-0016: anyone with it can drain custodial funds.

+# Runbook: Tracker upgrade path (rolling restart)
+
+Covers restarting/upgrading tracker processes in a hive without losing
+strike/ban/reputation state or interrupting settlement, per the ADR-0016 §4
+guarantee that reputation carries forward across restarts.
+
+## Trust assumptions (read first)
+
+Per [ADR-0016](../../../docs/adr/0016-alpha-scope-and-known-limitations.md),
+only one operator-designated tracker holds the treasury keypair and runs the
+settlement loop ([ADR-0015](../../../docs/adr/0015-usdt-custodial-settlement.md));
+other hive members replicate for routing only. Raft (`packages/tracker/meshnet_tracker/raft.py`)
+elects a leader for shard-assignment/registration commands — settlement
+leadership is a separate, operator-configured concept, not the Raft leader.
+Plan restarts so the settlement tracker's downtime window is minimized
+independent of routing-tracker restarts.
+
+## Known gap — read before relying on this runbook
+
+Strike/ban/reputation persistence itself was implemented in issue 05
+(`packages/contracts/meshnet_contracts/__init__.py::RegistryEventLog`,
+SQLite-backed, same pattern as billing/accounts). **As of this writing,
+`packages/tracker/meshnet_tracker/cli.py` does not expose a `--registry-db`
+flag, nor does it construct a `contracts=` instance to pass into
+`TrackerServer`.** Running the tracker via the stock CLI entry point leaves
+`server.contracts` as `None`, which means:
+
+- Ban checks (`_registration_ban_error`), reputation-weighted routing
+  (`_reputation_multiplier`), and the `/v1/registry/wallets` endpoint are
+  inert.
+- There is nothing to persist across restarts in that configuration — the
+  "survives restart" guarantee only holds for deployments that construct
+  `LocalSolanaContracts(registry_db=<path>)` and wire it into `TrackerServer(contracts=...)`
+  themselves (e.g. a custom entrypoint or embedding the server programmatically).
+
+Before following the restart steps below, confirm which mode this deployment
+runs in. If it's the stock CLI with no custom `contracts` wiring, strike/ban
+state is RAM-only regardless of this runbook, and a restart resets it — treat
+that as a pre-existing gap to flag to the owner, not something this runbook
+can work around.
+
+## Prerequisites
+
+- Confirm registry persistence is actually wired (see gap above) and note the
+  registry DB path in use.
+- Confirm billing (`--billing-db`) and accounts (`--accounts-db`) persistence
+  paths — these already default to `billing.sqlite` / `accounts.sqlite` and
+  persist regardless of the registry gap.
+- Know which tracker in the hive is currently the settlement leader (holds
+  `--treasury-keypair`) versus routing-only peers.
+- `--hive-secret` / `MESHNET_HIVE_SECRET` configured identically across all
+  hive members (ADR-0017) — a mismatched secret on restart fails gossip
+  closed, not open.
+- Take a [ledger backup](01-ledger-backup.md) before any upgrade that touches
+  schema or dependency versions.
+
+## Steps
+
+1. **Routing-only trackers first.** For each non-settlement tracker in the
+   hive:
+   a. Confirm it's not the current Raft leader (`GET /v1/raft/status`); if it
+      is, this restart forces a re-election — acceptable, but expect a brief
+      registration-proxy gap while a new leader is elected.
+   b. Stop the process, deploy the new code/config, restart with the same
+      `--billing-db` / `--accounts-db` / registry DB paths and the same
+      `--hive-secret` and `--cluster-peers`.
+   c. Check `/v1/raft/status` and `/v1/registry/wallets` (if registry is
+      wired) come back consistent with peers within one gossip interval.
+   d. Move to the next routing tracker only after this one rejoins cleanly.
+2. **Settlement tracker last**, and only during a low-settlement-activity
+   window if possible:
+   a. Confirm no payout is mid-flight (check tracker logs / pending balance
+      levels against `--settle-period` / `--payout-threshold`).
+   b. Stop the process. The treasury keypair file itself is untouched by the
+      restart — do not regenerate it (see
+      [treasury key rotation](02-treasury-key-rotation.md) for that separate
+      procedure).
+   c. Deploy new code/config, restart with identical `--treasury-keypair`,
+      `--solana-rpc-url`, `--usdt-mint`, `--settle-period`,
+      `--payout-threshold`, `--payout-dust-floor`, and DB paths.
+   d. Verify strike/ban/reputation state (if wired) matches pre-restart values
+      via `/v1/registry/wallets`, and that billing/accounts ledgers show the
+      same balances as immediately before shutdown.
+3. Confirm all hive members show each other as alive peers and gossip
+   (`/v1/registry/gossip`, `/v1/billing/gossip`, `/v1/accounts/gossip`) is
+   flowing without HMAC auth failures in logs (ADR-0017).
+
+## Rollback
+
+- Each tracker's on-disk SQLite files are untouched by a code-only upgrade;
+  rolling back means redeploying the previous binary/version against the same
+  DB paths. Because billing/accounts/registry are append-only event logs, a
+  version rollback does not lose data written by the newer version as long as
+  the schema didn't change — if the upgrade included a schema migration,
+  restore from the pre-upgrade [ledger backup](01-ledger-backup.md) instead.
+- If a settlement-tracker restart leaves it unable to reach the treasury RPC
+  endpoint, routing-only trackers continue serving traffic — settlement simply
+  pauses until the leader recovers; no funds are at risk since payouts require
+  the loaded keypair.
+
+## Secrets handling
+
+- Never commit `.env.devnet`, `--hive-secret` / `MESHNET_HIVE_SECRET`,
+  `--validator-service-token`, or the treasury keypair file as part of a
+  deploy/config change. Deploy scripts should read these from the existing
+  secrets store, not from a file checked into the repo.

+# ADR-0020: Lean Native Distributed GGUF Runtime
+
+Status: Accepted
+Date: 2026-07-13
+
+## Context
+
+The project currently uses Transformers/safetensors as its real model execution backend. This provides broad architecture coverage and a correctness reference, but reported and observed consumer CPU/GPU inference performance motivates evaluating llama.cpp/GGML and quantized GGUF.
+
+The product objective is not merely local GGUF serving. It is performant concurrent inference for top open models whose weights do not fit on one consumer node. The project already owns the Tracker, Inference Route, Route Session, Activation Seam, local Hot KV State, relay/direct transport, cancellation, telemetry, billing, and capability admission.
+
+Research audited llama.cpp RPC, GPUStack/llama-box, Nakshatra, prima.cpp, llama-gguf, LiGGUF, vLLM and its GGUF plugin, Petals, exo, and related projects. No repository provides the complete public-network contract. llama.cpp is the strongest GGUF execution substrate. vLLM has mature managed-cluster parallelism and scheduling concepts but its PP/TP/EP runtime assumes a static trusted distributed world and is unsuitable as the public Shard runtime.
+
+The project must remain lean and avoid combining several half-integrated inference control planes.
+
+## Decision
+
+### Primary native runtime
+
+Use llama.cpp/GGML through one standalone C++ Shard worker and a small exact-commit patch stack.
+
+The patch scope is limited to:
+
+- Range-aware GGUF tensor ownership/loading.
+- Architecture-defined intermediate boundary input/output.
+- Intermediate output before tail normalization/head.
+- Layer-filtered KV and external session-to-sequence mapping.
+
+Meshnet networking, routing, admission, billing, telemetry, and work evidence stay outside llama.cpp.
+
+Nakshatra, prima.cpp, llama-gguf, LiGGUF, and historical GPUStack are source/test donors only. Their repositories are not runtime dependencies.
+
+### Distributed parallelism
+
+The first public-network primitive is layer/pipeline parallelism through contiguous Shards in an Inference Route.
+
+Per-node continuous batching combines decode steps from compatible active Route Sessions. Multiple complete routes provide data parallelism.
+
+Tensor and expert parallel collectives may later operate inside one trusted composite node or managed cluster represented as one provider. They are not public WAN routing primitives.
+
+### Transport
+
+Use gRPC over HTTP/2 with Protocol Buffers for the native Python/C++ Shard data plane.
+
+- One long-lived bidirectional stream per Route Session Activation Seam.
+- Deadlines, cancellation, flow control, TLS/authentication hooks, structured status, and generated schemas.
+- Bounded chunks for prefill and a small decode fast path.
+- Existing relay infrastructure may carry the same versioned protobuf frames as opaque binary when direct connectivity is unavailable.
+- OpenAI client APIs remain HTTP/SSE; existing Tracker APIs remain unchanged.
+
+The boundary payload is a versioned named-tensor bundle because architecture boundaries may require more than one tensor.
+
+### vLLM
+
+Do not fork vLLM for public distributed Shards and do not transplant PagedAttention, Torch process groups, or the vLLM GGUF plugin into the llama.cpp worker.
+
+Allow unmodified vLLM as an optional whole-model backend or managed TP/PP/EP cluster represented as one logical provider.
+
+Adapt only small control-plane concepts:
+
+- Named intermediate bundles.
+- Continuous batching and request ownership.
+- Versioned cache-transfer compatibility fingerprints.
+- Explicit transfer failure/abort lifecycle.
+- Load telemetry and fair tie-breaking.
+
+### Benchmark gate
+
+GGUF performance is a hypothesis. Before expensive native work, compare the current Transformers/safetensors recipe with whole-model llama.cpp on controlled model, hardware, prompt, context, output, sampling, concurrency, memory, and quality lanes.
+
+Later distributed release gates use thresholds locked before implementation results are known. The native track stops if llama.cpp/GGUF offers neither a meaningful performance benefit nor a meaningful model-fit benefit at useful speed.
+
+### Concurrency
+
+A native worker must isolate `(Route Session ID, route epoch)` through a llama sequence or bounded context and must not serialize all generations behind one global serving sequence.
+
+The node admits sessions against weight/KV/scratch budgets, batches compatible decode steps, prevents prefill starvation, applies backpressure, and exposes queue/batch/KV telemetry.
+
+### Architecture certification
+
+Dense Llama-family is first. Qwen3/Qwen3-MoE is a separate explicit adapter. Every architecture/backend/recipe remains registered-but-dark until a real distributed forward, parity test, concurrency test, and capability admission pass.
+
+## Alternatives rejected
+
+### Fork vLLM for the public mesh
+
+Rejected because extracting its PP/TP/EP stages requires replacing static process groups, rank lifecycle, scheduler, request ownership, cache layout, failure behavior, and hardware assumptions. This would create a large difficult fork while discarding much of vLLM's core architecture.
+
+### llama.cpp RPC as the public protocol
+
+Rejected because it exposes coordinator-owned raw GGML devices, not independent Shards. Its trust, security, failure, cache, and per-node accounting model is unsuitable for arbitrary volunteer nodes.
+
+### Adopt Nakshatra or prima.cpp wholesale
+
+Rejected because their repositories, build reproducibility, session/concurrency semantics, architecture coverage, protocol identity, and control planes do not satisfy the project contract. Their partial-loading and boundary work remains valuable evidence.
+
+### Build a custom GGUF engine
+
+Rejected because llama.cpp already provides the parser, kernels, architecture graphs, KV, tokenizer, and heterogeneous backends. Reimplementing these would spread effort and increase correctness risk.
+
+### Invent a custom transport
+
+Rejected. gRPC/HTTP2 already provides mature streaming, flow control, deadlines, cancellation, TLS, and cross-language schema generation.
+
+## Consequences
+
+- The critical path contains Meshnet, one standalone worker, and one small pinned llama.cpp patch stack.
+- Transformers/safetensors remains the correctness reference and fallback for unsupported architectures.
+- Whole-model llama.cpp and vLLM managed clusters remain useful optional provider types.
+- The first milestone emphasizes controlled benchmark, parity, concurrent KV, and real two-machine evidence rather than a large-model demo.
+- Upstream collaboration with llama.cpp targets generic local hooks only; the project remains able to ship a narrow pinned fork if upstream acceptance takes time.
+- QUIC, public tensor parallelism, disaggregated prefill, speculative decode, route repair, and KV migration remain deferred until the core route passes release gates.
+
+## Verification gates
+
+1. Controlled safetensors-versus-GGUF performance contract.
+2. Two-process local range parity.
+3. Four-session concurrent KV isolation.
+4. Real two-machine execution using both Shards.
+5. End-to-end performance/fit advantage over the current distributed route.
+6. Separate Qwen3-family architecture certification.

+# GLM-5.2 Max distributed alpha roadmap
+
+Status: proposed executable epic target
+Last updated: 2026-07-13
+
+## Executive decision
+
+The alpha-release target is the exact open-weight model `zai-org/GLM-5.2` served with `reasoning_effort=max` from the smallest published Unsloth GGUF recipe, `UD-IQ1_S`, across multiple consumer machines.
+
+“Max” is a reasoning mode selected by the chat template/API request. It is not a separate model checkpoint.
+
+Alpha is earned only when the real target model:
+
+1. cannot fit within any one participating node's admitted memory;
+2. loads as contiguous layer Shards on at least two physical consumer machines;
+3. performs real GLM-5.2 MoE + DSA + IndexShare computation on every selected node;
+4. responds through the existing OpenAI-compatible Meshnet API with `reasoning_effort=max`;
+5. passes locked parity, usefulness, performance, telemetry, cancellation, and cleanup checks; and
+6. stores all model artifacts on configured mounted-drive storage, never under `/home`.
+
+The shortest safe path is not “support every GGUF architecture.” Dense Llama remains a small structural fixture. GLM-5.2 moves onto the critical path immediately after exact recipe identity and the pinned llama.cpp boundary. Qwen expansion, 1M context certification, MTP/speculative decoding, broad concurrency, and automatic route repair are post-alpha.
+
+## 1. Exact target contract
+
+### 1.1 Source model
+
+| Field | Locked target |
+|---|---|
+| Official repository | `zai-org/GLM-5.2` |
+| Official revision observed 2026-07-13 | `b4734de4facf877f85769a911abafc5283eab3d9` |
+| Model-weight license | MIT |
+| Official code/documentation license | Apache-2.0 |
+| Architecture | `glm_moe_dsa` / `GlmMoeDsaForCausalLM` |
+| Official architecture label | 744B total / approximately 40B active per token |
+| Exact stored checkpoint tensors | 753,329,940,480 parameters |
+| Transformer layers | 78 backbone layers plus one shared NextN/MTP layer in the artifact |
+| Layer types | first 3 dense; remaining 75 sparse MoE |
+| Routed experts | 256 |
+| Experts selected | 8 routed experts plus shared expert path |
+| Hidden width | 6,144 |
+| Attention | MLA under DSA, lightning indexer top-k 2,048 |
+| IndexShare | indexer roles are encoded by `indexer_types`; consumers reuse prior Full-layer indices |
+| Architectural maximum context | 1,048,576 tokens |
+| Alpha reasoning mode | `reasoning_effort=max` |
+
+The runtime must derive these values from the pinned artifact and fail closed on contradictory metadata. Marketing names are not compatibility identity.
+
+### 1.2 Alpha GGUF artifact
+
+| Field | Locked target |
+|---|---|
+| GGUF repository | `unsloth/GLM-5.2-GGUF` |
+| GGUF revision observed 2026-07-13 | `abc55e72527792c6e77069c99b4cb7de16fa9f23` |
+| Quantization | `UD-IQ1_S` |
+| Files | six GGUF shards |
+| Exact published bytes | 216,715,360,960 bytes |
+| Binary GiB | 201.832 GiB |
+| Published quality indication | about 76.2% top-1 agreement with the high-precision reference on Unsloth's quantization analysis |
+| Mounted storage rule | configured mounted drive only; never `/home` |
+
+Before downloading 216.7 GB, DGR-017 must generate a checked-in target manifest containing repository revisions, expected filenames, byte sizes, and resolved LFS SHA-256 values. Download is resumable and verified before route admission.
+
+`UD-IQ1_M` (228,492,966,624 bytes / 212.801 GiB) is the first diagnostic fallback if `UD-IQ1_S` exposes a runtime or quality defect. It does not satisfy the explicit “lowest quantization” alpha target unless the target contract is changed by human review.
+
+### 1.3 Runtime semantics required for alpha
+
+Required:
+
+- GGUF parsing and quantized kernels from one exact llama.cpp pin.
+- Correct GLM-5.2 MoE routing, selected experts, and shared expert.
+- Correct compressed MLA KV cache for locally owned layers.
+- Native DSA lightning indexer and sparse attention.
+- Correct IndexShare Full/Shared role execution from artifact metadata.
+- Range-owned contiguous transformer layers; each owned layer keeps all of its experts local.
+- Head-only embeddings and tail-only final norm/output head/sampling.
+- Architecture-defined activation boundary and optional DSA index sideband.
+- `reasoning_effort=max` chat-template behavior through the public API.
+- F32 seam correctness lane and a separately certified production activation dtype.
+
+Not required for alpha:
+
+- MTP/speculative decoding. The trailing NextN tensors may be loaded or explicitly excluded according to a certified recipe, but cannot be silently misinterpreted.
+- Full 1,048,576-token context.
+- Continuous batching beyond one target session.
+- Public-WAN tensor or expert parallel collectives.
+- Automatic mid-generation repair or KV migration.
+- Every CPU/GPU backend combination.
+
+## 2. Minimum resource envelope
+
+### 2.1 Weight and runtime memory
+
+The smallest artifact occupies 201.832 GiB before KV, DSA indexer state, scratch buffers, backend workspaces, process memory, and the operating system. **224 GiB aggregate runtime-accessible memory is only the experimental hard-fit floor**, consistent with Unsloth's approximate 223 GB one-bit requirement. It is not a conservative operational envelope.
+
+For admission, each node reserves:
+
+```text
+max(20% of physically usable memory, 8 GiB)
+```
+
+The remainder is the combined weight-plus-KV placement budget. Actual peak scratch is measured by backend/context and can force one extra node. Unified memory is counted once: integrated-GPU “VRAM” must not be added again to the same physical system RAM.
+
+| Physical usable tier | Minimum reserve | Weight + KV placement budget | IQ1_S 16K arithmetic minimum | Operational position |
+|---:|---:|---:|---:|---|
+| 32 GiB | 8.0 GiB | 24.0 GiB | 9 nodes | use 10 if attempted; latency-heavy |
+| 48 GiB | 9.6 GiB | 38.4 GiB | 6 nodes | possible; latency-heavy |
+| 64 GiB | 12.8 GiB | 51.2 GiB | 4 nodes | hard minimum; **5 recommended** |
+| 96 GiB | 19.2 GiB | 76.8 GiB | 3 nodes | recommended |
+| 128 GiB unified/system | 25.6 GiB | 102.4 GiB | 2 nodes | arithmetic hard minimum; **3 recommended** |
+
+The planner must use exact tensor byte ownership, not equal percentages. Embeddings, final head, dense versus MoE layers, shared experts, indexer tensors, quant block alignment, KV distribution, and backend workspace make equal layer counts unequal in memory.
+
+Recommended first target route: **three 96/128-GiB-class physical machines** or **five 64-GiB-class machines**, on the same wired switch with mounted model storage. Four 64-GiB or two 128-GiB machines are fit probes only and qualify solely if exact placement and measured peak-memory evidence retain the required reserve with no swap/overcommit.
+
+### 2.2 KV cache
+
+GLM-5.2 MLA caches 576 latent/rope values per token per backbone layer. Correct DSA also caches 128-dimensional indexer keys: ideally only for the 21 Full indexer layers, while the current experimental implementation may allocate them across all 78 layers. Alpha locks **Q8_0 KV** for quality and budgets the conservative current-implementation layout.
+
+| Context × concurrency | MLA-only Q8 | Optimized DSA Q8 | Conservative current-DSA Q8 | Conservative current-DSA F16 |
+|---:|---:|---:|---:|---:|
+| 16,384 × 1 | 0.73 GiB | 0.77 GiB | **0.89 GiB** | 1.68 GiB |
+| 131,072 × 1 | 5.83 GiB | 6.18 GiB | **7.12 GiB** | 13.41 GiB |
+| 1,048,576 × 1 | 46.62 GiB | 49.41 GiB | **56.98 GiB** | 107.25 GiB |
+
+These are planning estimates, not admission truth. The runtime must report measured allocated/resident MLA and indexer cache by Shard. Alpha configures a 16,384-token window, Q8_0 KV, and one session. Longer contexts and lower-bit KV are separate quality/resource certification gates.
+
+### 2.3 Activation seams and network
+
+A BF16 hidden-state boundary is 6,144 elements = 12,288 bytes/token before framing.
+
+- A 16,384-token prefill sends about 192 MiB per seam.
+- One decode token sends about 12 KiB per seam.
+- A 512-token decode sends about 6 MiB per seam.
+- Four nodes imply three serial seams.
+
+If a Shard boundary splits an IndexShare producer/consumer group, a 2,048-entry int32 top-k sideband can add up to 8 KiB/query before framing. The route planner should prefer boundaries that preserve complete IndexShare ownership groups. The protocol must still support and validate the named sideband because memory fit may force an internal group split.
+
+Decode bandwidth is small, but every generated token crosses all seams serially, so node count and per-hop latency dominate. Alpha requires a same-switch wired route: **2.5 GbE minimum and 10 GbE recommended**, with measured one-way/RTT, serialization, and queue latency. A 1 GbE route may be retained as fit-only evidence but is not the recommended alpha topology. Alpha records per-seam bytes, p50/p95 transfer latency, retries, and checksum failures; no speed claim is inferred from link rate alone.
+
+### 2.4 Storage
+
+The shortest alpha path allows every node to hold the complete six-file source GGUF while mapping/allocating only owned tensors. This minimizes artifact-transformation risk but costs 216.7 GB disk per node.
+
+Deterministic source-bound layer packages are a follow-up optimization. If needed before target fit, every package must retain:
+
+- source repository/revision and source file hashes;
+- exact owned tensor names, layer range, and endpoint role;
+- tokenizer/config identity;
+- deterministic package hash; and
+- proof that composing all packages matches the source tensor inventory.
+

+- DGR-001: immutable CPU contract plus separate signed ROCm diagnostic. CPU v1 remains `stop`; the GPU diagnostic establishes a viable fit/performance investigation lane but does not rewrite CPU evidence.
+- DGR-002: versioned backend-neutral gRPC/Protobuf Shard protocol with bounded fragments and compatibility checks.
+- Existing Meshnet: Tracker, contiguous Shards, Route Sessions/epochs, relay/direct transport, local Hot KV semantics in the reference backend, cancellation, telemetry, billing, and model-agnostic admission.
+
+### Missing before target alpha
+
+1. Exact GLM target/artifact manifest and memory-fit planner.
+2. A current llama.cpp pin proven to load and generate with the exact `UD-IQ1_S` artifact.
+3. A narrow decision on native GLM-5.2 DSA/IndexShare support. As observed 2026-07-13, merged llama.cpp PR #24770 loads GLM-5.2 through a dense-MLA compatibility path, while full IndexShare/DSA PR #25407 remains open and its generic sparse path can be slower than dense fallback. Generic CPU lightning-indexer support is merged; backend coverage remains uneven.
+4. A decode protocol amendment. `ActivationChunk` carries `TensorBundle`, but the current `DecodeStep` fast path carries only one `NamedTensor`; it cannot transport a hidden state plus GLM top-k sideband. Tail token/logit and sampling behavior also needs an explicit typed result contract.
+5. Correct range-owned GGUF loading and memory proof.
+6. GLM-specific boundary/KV/IndexShare semantics.
+7. Standalone native worker and Meshnet integration.
+8. Real target hardware route with no node individually able to admit the whole model.
+9. Locked target parity, usefulness, speed, failure, and cleanup evidence.
+
+### Donor policy
+
+`Mesh-LLM/mesh-llm` is a high-value test and patch donor. Its live GLM branch was observed with 261 llama.cpp patches, 167 named for GLM/DSA/MTP-related work. That is evidence of the problem's depth, not an acceptable maintained fork boundary.
+
+Audit and selectively reproduce the smallest independently understood pieces for:
+
+- GLM DSA graph semantics;
+- lightning indexer and sparse-attention tests;
+- IndexShare metadata/Full/Shared validation;
+- top-k sideband shape and lifecycle;
+- stage-local KV filtering; and
+- target parity/performance fixtures.
+
+Do not import Mesh-LLM routing, discovery, scheduler, public mesh, package manager, or full patch stack. Keep Meshnet as the sole control plane and collaborate narrowly upstream with llama.cpp/Mesh-LLM maintainers where practical.
+
+## 4. Revised roadmap
+
+## Phase 0 — lock the target before implementation
+
+### DGR-017: lock GLM-5.2 Max target and alpha contract
+
+Deliver:
+
+- machine-readable target manifest for official and GGUF revisions;
+- exact `UD-IQ1_S` file/size/hash inventory;
+- architecture/config/chat-template snapshot;
+- memory/KV/network planner with unified-memory de-duplication;
+- immutable alpha acceptance thresholds from section 5; and
+- current upstream/donor status report.
+
+Exit: target identity and alpha requirements are reviewable without downloading the model.
+
+## Phase 1 — establish a correct whole-model oracle
+
+### DGR-003: exact runtime recipe identity
+
+Extend the existing generic identity with GLM fields: DSA/IndexShare metadata, adapter version, reasoning template revision, activation bundle schema, KV dtype/layout, llama.cpp pin/patch hash, and target artifact manifest hash.
+
+### DGR-004: reproducible llama.cpp pin and narrow patch boundary
+
+Select a current exact upstream commit only after testing its stock GLM behavior. Add clean fetch/apply/build checks. Record every donor patch and whether it is adopted, rewritten, rejected, or waiting upstream.
+
+### DGR-018: certify whole-model GLM-5.2 runtime semantics
+
+On a 256-GiB-class reference host with at least 224 GiB runtime-accessible memory after OS reservation, or a measured equivalent:
+
+1. verify all six `UD-IQ1_S` shards;
+2. load with a stock pinned runtime and capture tensor/metadata warnings;
+3. prove whether DSA, IndexShare, shared expert, and Max template are actually active;
+4. add the minimum correctness patches/tests required;
+5. run deterministic prefill/decode and fixed Max-mode sentinel prompts; and
+6. sign the oracle recipe, output, telemetry, and limitations.
+
+Exit: one whole-model oracle exists for the same artifact/runtime semantics the distributed path will implement. “It emits text” is insufficient.
+
+## Phase 2 — build the generic local seam using small fixtures
+
+### DGR-005: range-owned GGUF tensors
+
+Keep dense Llama as a cheap structural fixture. Implement authoritative owned-tensor registration/loading, head/tail ownership, and measured resident-memory scaling. Design tensor classification so GLM adds explicit rules rather than unchecked name substitution.
+
+### DGR-006: architecture-defined boundary
+
+Implement named boundary bundles, F32 correctness lane, bounded fragmentation, and optional sidebands. Amend the decode fast path so it carries a versioned `TensorBundle` rather than one `NamedTensor`, while preserving a small one-tensor encoding. Define an explicit typed tail result for logits/token output and bind sampling/chat-template parameters to the recipe/request. Regenerate Python/C++ schema code and compatibility goldens. Dense fixture parity proves the seam mechanism, not GLM certification.
+
+Exit: two local processes can execute a small dense model with correct range ownership and boundary parity.
+
+## Phase 3 — add GLM-5.2 as the product adapter
+
+### DGR-019: implement and certify GLM-5.2 range/DSA/IndexShare semantics
+
+Deliver explicit support for:
+
+- 78 main layers and endpoint tensor ownership;
+- 256-expert MoE routing/top-8 and shared expert;
+- compressed MLA KV by owned layers;
+- DSA lightning indexer and sparse attention;
+- IndexShare metadata, Full producer, Shared consumer, and sideband behavior;
+- NextN/MTP tensor policy with MTP disabled or enabled explicitly;
+- shard-boundary planner aware of IndexShare ownership groups; and
+- whole-model versus two-stage parity against DGR-018.
+
+Exit: a same-host two-stage target run matches the locked oracle tolerance with real GLM computation in both stages. If the full target cannot fit on one host for this check, use a layer-reduced GLM architecture fixture for graph parity and defer full-artifact output parity to DGR-020; label the distinction explicitly.
+
+## Phase 4 — worker, KV, and Meshnet route
+
+Execute existing stories with GLM requirements included:
+
+1. DGR-007 — isolated local Hot KV keyed by `(Route Session, epoch)`, including DSA/IndexShare state.
+2. DGR-008 — standalone C++ gRPC worker.
+3. DGR-009 — Meshnet backend, capability, relay/direct, cancellation, and telemetry integration.
+4. DGR-010 — small-model local two-process acceptance.
+5. DGR-011 — real two-physical-machine route and heterogeneous fail-closed behavior.
+6. DGR-013 subset required by alpha — node loss, cancellation, stale epoch, restart, and memory/KV cleanup.
+
+Continuous batching (DGR-012) is deliberately not an alpha dependency. The first target release supports one admitted GLM route session; concurrency follows after target correctness and fit.
+
+## Phase 5 — target alpha gate
+
+### DGR-020: pass real distributed GLM-5.2 Max alpha acceptance
+
+Use at least two physical machines and enough aggregate usable memory to meet the locked target planner. No participating node may individually admit the complete target. All stages must report real compute and exact tensor ownership.
+
+Run the complete acceptance matrix in section 5, preserve raw logs/metrics/output, sign the evidence, and publish an explicit `alpha` or `stop` verdict. Thresholds cannot be weakened after results are known.
+
+## Phase 6 — post-alpha hardening
+
+After DGR-020 passes:
+
+1. DGR-012 — 1/2/4-session continuous batching and bounded admission.
+2. DGR-014 — final distributed GGUF versus reference-route performance decision.
+3. 32K, 128K, 200K, then 1M context certification with quantized KV.
+4. MTP/speculative decoding.
+5. Deterministic range packages to remove full-artifact replication.
+6. Additional backend compatibility classes and route topologies.
+7. DGR-016 — narrow upstream collaboration package, split by independently reviewable llama.cpp changes.
+8. DGR-015 — Qwen3/Qwen3-MoE only as later architecture expansion, not as the GLM alpha target.
+
+## 5. Locked alpha acceptance matrix
+
+These thresholds are set before target execution.
+
+### 5.1 Identity and fit
+
+- Exact official and GGUF repository revisions match the target manifest.
+- All six source GGUF sizes and LFS SHA-256 values verify.
+- Every route node reports owned tensor names/bytes, layer range, endpoint role, backend, KV recipe, and patch fingerprint.
+- Union of owned tensors equals the certified runtime-required tensor inventory; unintended overlap is zero.
+- No node's weight-plus-KV placement budget can hold the complete recipe.
+- Every node reserves at least `max(20% of physically usable memory, 8 GiB)` outside weight-plus-KV placement; measured peak scratch must remain inside that reserve.
+- Aggregate peak RSS/VRAM stays within physical budgets with no swap, overcommit, mmap-only, or double-counted unified-memory success claim.
+- Arithmetic-minimum topologies require exact contiguous tensor placement evidence; recommended alpha topology is 5×64 GiB or 3×96/128 GiB.
+- Unified RAM/VRAM is not double-counted.
+
+### 5.2 Semantic correctness
+
+- Logs and graph tests prove GLM MoE/shared-expert, DSA lightning indexer, sparse attention, and IndexShare Full/Shared paths are active; dense-attention compatibility fallback cannot satisfy alpha.
+- `reasoning_effort=max` is observable in the rendered template/API recipe.
+- F32 same-backend seam fixture: 32 greedy decode tokens exactly match the whole-model oracle and activation tolerance is locked by DGR-006.
+- Production seam on the fixed prompt corpus: greedy token agreement is at least 0.90 and mean compared-state/logit cosine similarity is at least 0.999 versus DGR-018, with no malformed or non-finite tensors.
+- Incompatible artifact, tokenizer, adapter, DSA metadata, boundary, activation, KV, backend class, or runtime patch fingerprints fail closed.
+
+### 5.3 End-to-end target run
+
+- Context configured to 16,384 tokens with Q8_0 MLA/indexer KV.
+- Fixed 4,096-token prompt lane completes prefill.
+- Route uses a same-switch wired network; 2.5 GbE is the alpha minimum and 10 GbE is recommended.
+- One Max-mode request generates at least 512 output tokens or reaches a valid natural EOS after at least 128 tokens.
+- Fixed coding, structured tool-call/JSON, and multi-step reasoning sentinels produce parseable, relevant outputs; raw prompts and outputs are retained for review.
+- OpenAI-compatible response includes stable model ID, finish reason, and token usage.
+
+### 5.4 Minimum useful performance
+
+On the declared minimum alpha topology after one warm-up:
+
+- median decode throughput is at least 0.5 generated token/s for the fixed Max-mode lane;
+- 4,096-token-prompt TTFT is at most 10 minutes;
+- no unexplained stall exceeds 60 seconds without progress telemetry;
+- per-stage compute, queue, KV, seam bytes/latency, RSS/VRAM, and backend timing are present; and
+- results are labeled by hardware/topology and are not generalized to other consumer systems.
+
+If output quality passes but the speed floor fails, verdict is `stop` for alpha and the evidence selects the next optimization target. It is not relabeled as success merely because the model loaded.
+
+### 5.5 Reliability and security
+
+- Two consecutive cold starts load, generate, release, and exit cleanly.
+- Cancellation during prefill and decode releases every stage's queued buffers and KV lease.
+- One worker loss aborts the route; alpha retries only from token zero on a new compatible route.
+- Stale epochs and duplicate step IDs are rejected.
+- Artifact paths stay outside `/home`; logs contain no secrets or unrestricted prompt payloads.
+- Synthetic workers and layer-reduced fixtures are labeled unit/integration coverage and cannot satisfy target alpha.
+
+## 6. First execution order
+
+The next unattended work should run in this order:
+
+1. DGR-017 — target contract, manifest, planner, and upstream status.
+2. DGR-003 — exact recipe identity.
+3. DGR-004 — current llama.cpp pin and minimal patch harness.
+4. Run in parallel:
+   - DGR-018 — whole-model oracle on a 256-GiB-class host with at least 224 GiB runtime-accessible memory.
+   - DGR-005 and DGR-006 — generic range/boundary seam on local small fixtures.
+5. DGR-019 — GLM semantics and parity after both parallel lanes pass.
+6. DGR-007 through DGR-011 — native worker and real transport route.
+7. Required DGR-013 failure subset.
+8. DGR-020 — real target alpha verdict.
+
+The first external hardware blocker is DGR-018, but DGR-005/DGR-006 proceed locally while that host is sourced. Do not download the full model until DGR-017's exact manifest and storage preflight pass.

+# PRD: Performant Concurrent Distributed GGUF Runtime
+
+## Overview
+
+Build one lean native GGUF execution path that lets an Inference Route combine consumer machines to serve models larger than any one node can hold. Reuse the existing Meshnet control plane and llama.cpp/GGML execution engine. Adopt gRPC/HTTP2 and Protocol Buffers for the native Shard worker data plane rather than inventing a transport.
+
+The program is benchmark-gated. GGUF is not assumed faster merely because it is quantized or uses a different file format. The first story compares the current Transformers/safetensors backend against whole-model llama.cpp on controlled model/hardware/quality lanes and locks a performance contract. Native distributed work proceeds only when GGUF provides a meaningful speed or fit benefit.
+
+The alpha target is now exact: `zai-org/GLM-5.2` at a pinned revision, the lowest published Unsloth `UD-IQ1_S` GGUF, and `reasoning_effort=max`, distributed across physical consumer machines. See [GLM-5.2-MAX-ALPHA-ROADMAP.md](GLM-5.2-MAX-ALPHA-ROADMAP.md). Dense Llama is a cheap structural fixture; Qwen is post-alpha expansion.
+
+## Goals
+
+- Execute one GGUF model across independently addressable contiguous Shards.
+- Retain Hot KV State locally for each Shard and isolate concurrent Route Sessions.
+- Batch compatible decode steps across active sessions for aggregate throughput.
+- Use consumer CPU, AMD, NVIDIA, Vulkan, Metal, and mixed routes only where a real certified forward passes.
+- Beat the current distributed safetensors route under a controlled performance contract or enable a larger otherwise-unroutable model at useful measured speed.
+- Keep the critical path to Meshnet plus a small pinned llama.cpp fork and standalone C++ worker.
+- Produce narrow upstream collaboration material for llama.cpp without placing Meshnet networking or economics inside upstream.
+- Pass an immutable GLM-5.2 Max `alpha`/`stop` gate with native MoE, DSA, IndexShare, parity, usefulness, speed, failure, and cleanup evidence.
+
+## Quality Gates
+
+Every story must:
+
+- Run its targeted `pytest` tests.
+- Run `python -m compileall packages tests` for Python changes.
+- Run `git diff --check`.
+- Keep default tests deterministic, model-download-free, API-credit-free, and GPU-free.
+- Preserve existing Transformers/safetensors behavior unless the story explicitly changes a versioned compatibility contract.
+
+Stories touching the native worker must also:
+
+- Build the pinned C++ target with CMake.
+- Run focused C++/protocol tests through CTest or the documented equivalent.
+- Verify the llama.cpp patch stack applies cleanly to the exact pinned commit.
+
+Real-model/hardware stories must:
+
+- Require `MESHNET_ENABLE_REAL_INFERENCE_TESTS=1`.
+- Use the machine-specific mounted-drive model path and the certified runtime environment; never place model artifacts under `/home`.
+- Record exact model revision, artifact hash, runtime recipe, hardware, driver/backend, commands, raw JSON metrics, and output-quality result.
+- Label synthetic tests as unit coverage rather than distributed acceptance.
+
+Before a story is marked complete, run the full deterministic `pytest -q` suite or record the exact pre-existing unrelated failure with a clean-tree reproduction.
+

+- **Done (`passes: true`):** DGR-001, DGR-002, DGR-003, DGR-004, DGR-005,
+  DGR-006, DGR-017.
+- **Blocked on hardware:** DGR-018 requires a 256-GiB-class host with at least
+  224 GiB runtime-accessible memory and 250 GB free storage outside `/home`;
+  no such host is currently available (development host: 124.9 GiB MemTotal).
+  Exact preflight output: [evidence/DGR-018/BLOCKED.md](evidence/DGR-018/BLOCKED.md).
+  DGR-019 (needs the DGR-018 oracle) and DGR-020 (needs DGR-018/DGR-019 plus
+  multiple physical consumer nodes) are blocked transitively.
+- **Consequence of the graph as written:** DGR-007 depends on DGR-019, so every
+  remaining story (DGR-007 through DGR-016) is transitively blocked on the
+  256-GiB host. Unblocking the generic dense pipeline without that host would
+  require an explicit re-planning decision to relax the DGR-007 → DGR-019
+  dependency; that decision is out of scope for maintenance and has not been
+  made.
+
+## User Stories
+
+### DGR-001: Lock the safetensors-versus-GGUF performance contract
+**Description:** As a runtime engineer, I need a controlled baseline so that GGUF work proceeds from measured speed, memory, and quality rather than reputation.
+
+**Acceptance Criteria:**
+- [ ] Benchmark the same model architecture/revision, machine, prompts, context lengths, output lengths, sampling policy, and concurrency across the current Transformers/safetensors recipe and whole-model llama.cpp recipes.
+- [ ] Separate correctness/quality lanes from quantized performance/fit lanes instead of claiming BF16 and Q4 are numerically equivalent.
+- [ ] Report TTFT, prefill tok/s, decode tok/s, p50/p95 latency, aggregate throughput, RSS, VRAM, artifact size, failures, and output drift in machine-readable JSON.
+- [ ] Add concurrency levels 1 and 4 where memory permits.
+- [ ] Write a versioned performance contract consumed by later release gates, including an explicit stop condition when llama.cpp/GGUF has no meaningful speed or fit benefit.
+
+### DGR-002: Adopt the versioned gRPC Shard protocol
+**Description:** As a node developer, I need a battle-proven streaming protocol so that Python and C++ Shards communicate without a custom socket protocol.
+
+**Acceptance Criteria:**
+- [ ] Add a Protocol Buffers schema for capability, health, session stream, release, and cancellation operations.
+- [ ] Define one long-lived bidirectional gRPC stream per Route Session Activation Seam with deadlines, cancellation, flow control, and structured errors.
+- [ ] Define bounded chunking for prefill and a small decode fast path.
+- [ ] Carry schema version, request/work ID, Route Session ID, route epoch, artifact/recipe fingerprint, Shard range/effective start, phase, position, idempotency step, cache expectation, compression, and checksum.
+- [ ] Define a versioned named-tensor bundle with per-tensor name, shape, dtype, byte order, and payload fragments.
+- [ ] Add generated-schema round-trip and compatibility tests in Python and C++.
+
+### DGR-003: Define exact Artifact and runtime recipe identity
+**Description:** As the Tracker, I need exact compatibility identity so that only numerically and operationally compatible Shards form an Inference Route.
+
+**Acceptance Criteria:**
+- [ ] Separate weight quantization, activation dtype, compute dtype, KV dtype/layout, tokenizer revision, architecture adapter, backend, and runtime version.
+- [ ] Bind derivative or split artifacts to an exact source Model Artifact hash and Shard range.
+- [ ] Produce a stable compatibility fingerprint used by capability admission and the gRPC handshake.
+- [ ] Fail closed on mismatched artifact, tokenizer, architecture, range, boundary schema, activation recipe, or cache layout.
+- [ ] Keep unsupported recipes registered-but-dark until a real distributed forward certifies them.
+
+### DGR-004: Create the reproducible pinned llama.cpp patch stack
+**Description:** As a maintainer, I need a small auditable fork boundary so that upstream updates do not turn the runtime into an unmaintainable stitched codebase.
+
+**Acceptance Criteria:**
+- [ ] Pin one exact llama.cpp commit through a reproducible source dependency mechanism.
+- [ ] Store a numbered minimal patch stack separately from Meshnet networking code.
+- [ ] Add a build script that applies/checks patches and builds the standalone worker without manual source copying.
+- [ ] Record upstream file/ABI assumptions and fail clearly when the pin changes.
+- [ ] Preserve upstream license and attribution notices.
+- [ ] Add a clean rebuild smoke test that does not download a model.
+
+### DGR-005: Implement dense-Llama range-aware GGUF ownership
+**Description:** As a node, I need to map only my assigned dense-Llama Shard so that aggregate consumer memory can hold a model larger than one node.
+
+**Acceptance Criteria:**
+- [ ] Register and allocate only `blk.N.*` tensors in the assigned range.
+- [ ] Load embeddings only for the head and final norm/LM head only for the tail, including tied embeddings.
+- [ ] Prefer range-aware mapping from one exact source GGUF; if derivative sub-GGUFs are used temporarily, verify source/slice hashes and avoid claiming final artifact semantics.
+- [ ] Report authoritative loaded range and endpoint ownership from the model, not operator CLI claims.
+- [ ] Demonstrate mapped/resident memory scales with owned tensors rather than full model size.
+
+### DGR-006: Implement architecture-defined boundary input/output
+**Description:** As a Shard, I need to consume and emit the correct transformer boundary state so that disjoint processes reproduce whole-model execution.
+
+**Acceptance Criteria:**
+- [ ] Head accepts token IDs and owns token embedding.
+- [ ] Middle/tail bypass token embedding and accept the named boundary bundle.
+- [ ] Amend the decode fast path from one `NamedTensor` to a versioned `TensorBundle`, preserving compact one-tensor compatibility and regenerating Python/C++ protocol goldens.
+- [ ] Define a typed tail logits/token result with sampling and chat-template/reasoning identity.
+- [ ] Non-tail emits the unnormalized architecture-defined residual/boundary before final norm/head and before tail-only row pruning.
+- [ ] Tail emits logits or token output through an explicit sampling contract.
+- [ ] Dense-Llama whole-model versus two-range prefill and greedy-decode parity passes the documented tolerance.
+- [ ] The adapter interface fails closed for uncertified architectures.
+
+### DGR-007: Add isolated concurrent local Hot KV State
+**Description:** As a client, I need concurrent Route Sessions to retain independent per-Shard cache so that one request cannot clear or corrupt another.
+
+**Acceptance Criteria:**
+- [ ] Map `(Route Session ID, route epoch)` to an isolated llama sequence or bounded context.
+- [ ] Allocate KV only for owned layers.
+- [ ] Support prefill append, decode append, truncate, release, TTL/LRU eviction, and explicit cache-miss response.
+- [ ] Reject stale epochs and incompatible cache recipes.
+- [ ] At least four concurrent sessions on a small model complete without token or KV cross-talk.
+- [ ] Cancellation/release of one session leaves other sessions intact and memory returns to the configured budget.
+
+### DGR-008: Build the standalone C++ gRPC Shard worker
+**Description:** As a node runtime, I need one supervised native process so that llama.cpp internals remain behind a stable project-owned protocol.
+
+**Acceptance Criteria:**
+- [ ] Worker exposes capability, health, session stream, release, cancellation, and metrics services from DGR-002.
+- [ ] Worker loads one exact Artifact/recipe/Shard identity and refuses mismatched requests.
+- [ ] Streaming path enforces bounded messages, flow control, deadlines, idempotency, and independent session cancellation.
+- [ ] Worker does not expose raw llama.cpp RPC or arbitrary GGML graph execution.
+- [ ] Graceful shutdown releases sessions; crash behavior is bounded and observable.
+- [ ] Python integration tests run against a fake model mode without model downloads.
+
+### DGR-009: Integrate the native worker with Meshnet
+**Description:** As the existing node service, I need a GGUF Shard backend adapter so that the Tracker, relay, billing, telemetry, and capability admission remain the sole control plane.
+
+**Acceptance Criteria:**
+- [ ] Implement the existing model-backend surface without changing Transformers behavior.
+- [ ] Registration carries exact validated GGUF recipe, Shard, backend and concurrency/KV capacity.
+- [ ] Tracker forms only complete compatible routes and keeps uncertified recipes dark.
+- [ ] Direct routes use gRPC streams; relayed routes carry the same versioned protobuf frames as opaque binary through the existing relay seam.
+- [ ] Existing request/work IDs, cancellation, Generation Telemetry, billing, and per-node attribution remain correlated.
+- [ ] No vLLM, Nakshatra, prima.cpp, or custom-engine control plane becomes a core dependency.
+
+### DGR-010: Pass local real-model two-process acceptance
+**Description:** As a release engineer, I need real local distributed parity before involving network variability.
+
+**Acceptance Criteria:**
+- [ ] Two local worker processes open disjoint dense-Llama ranges from the certified Artifact.
+- [ ] Prefill and at least 32 greedy decode tokens match whole-model llama.cpp within the certified tolerance.
+- [ ] Each worker retains only its own tensors and Hot KV State.
+- [ ] Four concurrent Route Sessions pass isolation and cleanup checks.
+- [ ] Report TTFT, prefill/decode throughput, seam bytes/latency, worker RSS/VRAM, KV memory, batch size, and queue time.
+- [ ] Killing one worker produces a bounded structured failure rather than a deadlock.
+
+### DGR-011: Pass a real heterogeneous two-machine route
+**Description:** As a consumer-hardware operator, I need two physical machines to execute one GGUF model so that the distributed claim is real.
+
+**Acceptance Criteria:**
+- [ ] Tracker selects two physical nodes with disjoint Shards and one exact certified recipe/compatibility class.
+- [ ] Actual CPU/GPU execution occurs on both nodes; synthetic workers do not satisfy acceptance.
+- [ ] Prefill/decode, concurrent-session isolation, telemetry, cancellation, and cleanup pass over the real transport/relay path.
+- [ ] Exact hardware, network, backend, model hash, route, commands, and raw metrics are recorded.
+- [ ] A model or recipe larger than one participating node's admitted memory is exercised when available.
+- [ ] Output drift is measured and incompatible mixed backends fail closed.
+
+### DGR-012: Implement continuous batching and bounded admission
+**Description:** As a node operator, I need active sessions batched safely so that concurrency increases aggregate throughput rather than serializing every request.
+
+**Acceptance Criteria:**
+- [ ] Node scheduler admits sessions against weight, KV, scratch, and queue budgets.
+- [ ] Compatible decode steps from multiple sessions form llama.cpp batches while preserving per-session positions and outputs.
+- [ ] Prefill does not starve decode; scheduling policy and bounds are explicit.
+- [ ] Backpressure prevents unbounded queued activations or KV growth.
+- [ ] Capability telemetry reports active sessions, queue depth, batch occupancy, KV pressure, prefill/decode rates, and rejected admissions.
+- [ ] Concurrency 1/2/4/8 benchmark identifies saturation and shows no cross-session corruption.
+
+### DGR-013: Harden failure, cancellation, and restart semantics
+**Description:** As a client, I need failures to be bounded and explicit so that distributed speed does not come with hanging or corrupted generations.
+
+**Acceptance Criteria:**
+- [ ] Deadlines and heartbeat/health loss terminate blocked stream operations.
+- [ ] Cancellation propagates across every Shard and releases local KV and queued buffers.
+- [ ] Duplicate steps are idempotent; uncertain mutations are never replayed silently.
+- [ ] Alpha failover restarts from token zero on a newly compatible route rather than importing unverified KV.
+- [ ] Worker death, stream reset, malformed bundle, stale epoch, and cache miss tests pass.
+- [ ] Billing/work records distinguish completed, cancelled, failed, and unverified work.
+
+### DGR-014: Enforce the GGUF-versus-safetensors release gate
+**Description:** As the product owner, I need an end-to-end comparison so that the native runtime ships only if it advances model access or performance.
+
+**Acceptance Criteria:**
+- [ ] Run current distributed safetensors and distributed GGUF routes on the same certified model/hardware/network scenario where technically comparable.
+- [ ] Report quality, TTFT, prefill/decode throughput, aggregate concurrency throughput, p95 latency, seam cost, memory, KV pressure, failures, and cleanup.
+- [ ] Evaluate against the DGR-001 performance contract without changing thresholds after seeing results.
+- [ ] Ship recommendation is one of: promote GGUF, optimize a measured bottleneck with a new bounded task, or stop the native track.
+- [ ] Results clearly separate quantization gains from transport/runtime gains.
+
+### DGR-015: Add and certify a Qwen3/Qwen3-MoE adapter
+**Description:** As a client seeking top models, I need a separately certified MoE-capable architecture after the dense runtime proves stable.
+
+**Acceptance Criteria:**
+- [ ] Implement explicit tensor ownership, router/top-k, expert/shared-expert, Q/K normalization, boundary bundle, and cache semantics for the selected Qwen3 family recipe.
+- [ ] Do not reuse the dense-Llama adapter through unchecked name substitutions.
+- [ ] Whole-model versus distributed prefill/decode parity passes the architecture-specific tolerance.
+- [ ] Expert memory ownership and communication are measured.
+- [ ] Real consumer-hardware acceptance and capability admission pass before the recipe becomes routable.
+
+### DGR-016: Produce the upstream llama.cpp collaboration package
+**Description:** As a maintainer, I need narrow upstreamable proposals so that our patch burden can shrink without asking llama.cpp to own Meshnet networking.
+
+**Acceptance Criteria:**
+- [ ] Separate generic llama.cpp hooks from Meshnet protocol/control-plane code.
+- [ ] Prepare minimal reproducible examples and tests for range-aware loading, boundary input/output, and layer-filtered KV.
+- [ ] Compare the proposal with Nakshatra and prima.cpp evidence and explain why the API is generally useful.
+- [ ] Preserve one scoped commit/patch per concern against the exact upstream pin.
+- [ ] Produce an outreach document suitable for Georgi/llama.cpp maintainers; actual sending remains a human action.
+
+### DGR-017: Lock the GLM-5.2 Max target and alpha contract
+**Description:** Pin exact official/GGUF revisions, `UD-IQ1_S` files and hashes, Max-mode semantics, resource accounting, and immutable target thresholds before implementation results exist.
+
+**Acceptance Criteria:**
+- [ ] Produce machine-readable target, resource, upstream-status, and immutable acceptance contracts without downloading full weights.
+- [ ] Distinguish the 224-GiB hard-fit floor from the recommended 5×64 or 3×96/128 topology, using Q8 KV, 20%/8-GiB node reserves, and a wired 2.5-GbE minimum.
+- [ ] Count unified RAM/VRAM once and test revision/shard/byte/threshold mutation failures.
+
+### DGR-018: Certify whole-model GLM-5.2 runtime semantics
+**Description:** Establish the exact IQ1_S oracle on a 256-GiB-class host with at least 224 GiB runtime-accessible memory; lock Q8_0 MLA/indexer KV and native target semantics before distributed parity work.
+
+**Acceptance Criteria:**
+- [ ] Verify the complete artifact and prove native MoE/shared expert, DSA, IndexShare, KV, NextN policy, and Max-template behavior.
+- [ ] Dense/replicated compatibility fallback cannot become the oracle merely because it emits text.
+
+### DGR-019: Implement and certify GLM-5.2 range, DSA, and IndexShare semantics
+**Description:** Add explicit target-model tensor, graph, boundary, sideband, and local-KV ownership after the generic dense seam.
+
+**Acceptance Criteria:**
+- [ ] Preserve MoE/shared expert, DSA lightning indexer/sparse attention, and IndexShare Full/Shared semantics across contiguous Shards.
+- [ ] Pass locked fixture/target parity and measured per-Shard memory ownership; never claim full-target parity from a reduced fixture.
+
+### DGR-020: Pass real distributed GLM-5.2 Max alpha acceptance
+**Description:** Run the exact lowest-quant target through Meshnet on enough physical consumer nodes that no node can admit the whole recipe.
+
+**Acceptance Criteria:**
+- [ ] Pass the immutable identity, semantic, parity, Max-mode usefulness, 0.5 token/s, TTFT, reliability, and mounted-storage gates.
+- [ ] Preserve signed raw evidence and emit `alpha` only if every target criterion passes; otherwise emit `stop`.
+
+## Functional Requirements
+
+1. The public distributed primitive is an ordered Inference Route of contiguous Shards.
+2. The native runtime uses llama.cpp/GGML; vLLM remains optional as a complete managed provider.
+3. Native worker communication uses gRPC/HTTP2 and Protocol Buffers with one stable stream per Route Session Activation Seam.
+4. Artifact identity, runtime recipe, boundary schema, activation dtype and cache layout must match exactly before routing.
+5. Hot KV State remains local to the node serving the Shard.
+6. Multiple Route Sessions must execute concurrently without shared-cache corruption.
+7. Nodes batch compatible active decode steps and enforce bounded admission/backpressure.
+8. Unsupported architectures and hardware recipes remain non-routable until real certification passes.
+9. Default tests never download models or require GPUs; real tests are explicit and preserve artifacts off `/home`.
+10. The release decision is based on measured performance, fit, quality, concurrency, and reliability relative to the safetensors baseline.
+
+## Non-Goals
+
+- Forking vLLM or importing its PagedAttention/Torch distributed runtime.
+- Adopting Nakshatra, prima.cpp, llama-gguf, LiGGUF, or GPUStack as the control plane.
+- Public WAN tensor/expert parallel collectives.
+- QUIC, WebRTC, or a custom socket protocol.
+- Automatic KV migration or mid-generation route repair in the first release.
+- Speculative decoding or disaggregated prefill before the core release gate.
+- Supporting every GGUF architecture before the exact GLM-5.2 target; Qwen3-family certification is post-alpha.
+- A marketing-scale model demo that bypasses parity, concurrency, admission, or performance gates.
+
+## Success Metrics
+
+- A real model larger than one admitted node can execute across consumer machines when suitable hardware/artifacts are available.
+- Four or more concurrent sessions complete without cross-talk; hardware-specific saturation is measured.
+- Distributed GGUF passes the locked performance/fit contract against the existing safetensors route.
+- Worker and Tracker recover all resources after completion, cancellation, malformed input, and node failure.
+- The critical runtime remains Meshnet plus one standalone worker and a small auditable llama.cpp patch stack.
+
+## Open Questions
+
+- DGR-001 remains immutable. DGR-017 locks the exact GLM-5.2/`UD-IQ1_S` target and alpha thresholds without rewriting DGR-001 evidence.
+- Final hardware-specific concurrency and useful-speed thresholds are locked by measured baselines rather than guessed globally.
+- Upstream llama.cpp acceptance is desirable but not a prerequisite for the first narrow pinned fork.

+# Ralph execution context: Performant Concurrent Distributed GGUF Runtime
+
+Status: authoritative context for every fresh Ralph iteration
+Last updated: 2026-07-13
+
+## Mandatory startup sequence
+
+Before changing code, every Ralph agent must:
+
+1. Read this file completely.
+2. Read the selected issue under `.scratch/distributed-gguf-runtime/issues/`.
+3. Read `.scratch/distributed-gguf-runtime/GLM-5.2-MAX-ALPHA-ROADMAP.md`, `.scratch/distributed-gguf-runtime/ADR-0020-distributed-gguf-runtime.md`, and the relevant part of `architecture.md`.
+4. Read `.claude/memory/MEMORY.md` and root `CONTEXT.md` for current project vocabulary and constraints.
+5. Inspect the current implementation and tests; do not assume historical scratch text describes live code.
+6. Read the evidence/handoff directories for every declared dependency.
+7. Inspect `git status` and preserve all pre-existing working-tree changes.
+
+A fresh Ralph iteration has no conversational memory. These files are the context contract.
+
+## Story sizing and interruption rule
+
+Each story is intended to fit one focused Ralph context. Before implementation, estimate whether every acceptance criterion can be completed and verified in the current iteration.
+
+If the story is too large, an external dependency is unavailable, or the context/provider limit prevents completion:
+
+- Do not weaken criteria.
+- Do not mark the issue done or set `passes: true`.
+- Avoid leaving an unverified cross-cutting partial implementation when a smaller safe spike is possible.
+- Write `evidence/<TASK-ID>/DECOMPOSITION.md` or `BLOCKED.md` with the exact blocker, current verified state, proposed child stories, dependency graph and rollback/continuation instructions.
+- Stop for supervised review.
+
+If interrupted after code changes, record every changed file, command result and unresolved invariant so the next fresh loop can verify rather than guess.
+
+## Product objective
+
+Build performant, concurrent distributed inference that combines consumer machines to serve top open models that exceed one node's RAM/VRAM.
+
+The alpha target is the exact pinned GLM-5.2 `UD-IQ1_S` artifact served with `reasoning_effort=max` across physical consumer machines. Dense Llama is a structural fixture. Synthetic workers, dense-attention compatibility fallback, a smaller model, or a single host cannot satisfy target alpha. The immutable target contract and resource envelope are in `GLM-5.2-MAX-ALPHA-ROADMAP.md`.
+
+A distributed demo is not success. The product must provide:
+
+- Useful measured prefill and decode speed.
+- Multiple concurrent Route Sessions.
+- No KV/token cross-talk.
+- Bounded memory, queues, cancellation and failures.
+- Real execution on every participating node.
+- A model-fit or performance advantage over the current Transformers/safetensors route.
+
+## Critical-path architecture
+
+```text
+Existing Meshnet control plane
+        |
+Versioned Protobuf over gRPC/HTTP2
+        |
+Project-owned standalone C++ Shard worker
+        |
+Small exact-commit llama.cpp patch stack
+```
+
+Meshnet remains the only control plane and owns:
+
+- Tracker registration, Coverage Map, route selection and route epochs.
+- Route Sessions and Activation Seams.
+- Direct/relay routing.
+- Capability admission.
+- Cancellation, Generation Telemetry and backpressure.
+- Billing, validation and per-node work attribution.
+
+Do not introduce another scheduler/control plane from vLLM, Nakshatra, prima.cpp, llama-gguf, GPUStack or another project.
+
+## Runtime decisions that are not open
+
+1. Public-network Shards are contiguous transformer layer ranges.
+2. llama.cpp/GGML is the native GGUF execution substrate.
+3. The project owns a small standalone worker and a narrow pinned llama.cpp patch stack.
+4. The native Shard protocol is Protocol Buffers over gRPC/HTTP2.
+5. One long-lived bidirectional stream serves one Route Session Activation Seam.
+6. The public activation boundary is a versioned named-tensor bundle.
+7. Hot KV State remains local to the node serving the Shard.
+8. `(Route Session ID, route epoch)` maps to an isolated llama sequence or bounded context.
+9. Concurrency uses continuous batching of compatible active sessions inside each node.
+10. Transformers/safetensors remains the correctness and performance baseline.
+11. vLLM may be an optional complete managed provider and concept donor; it is not forked into public Shards.
+12. Tensor/expert collectives are deferred to a trusted composite provider, not public WAN routes.
+13. Unsupported architectures/backends remain registered-but-dark until real certification passes.
+14. Alpha failure retries from token zero; unverified KV is never migrated silently.
+15. Model artifacts must remain on mounted-drive storage and never under `/home`.
+16. Unified system RAM and integrated-GPU memory are one physical pool and must never be double-counted for admission.
+17. Alpha requires native GLM-5.2 MoE, DSA, and IndexShare semantics; MTP/speculative decoding and 1M-context certification are post-alpha.
+18. DGR-006 amends the decode fast path to carry a versioned `TensorBundle` and defines a typed tail logits/token result; the current single-`NamedTensor` fast path is insufficient for GLM sidebands.
+19. Alpha reserves at least `max(20% of physical usable memory, 8 GiB)` per node outside weight-plus-Q8-KV placement and uses a same-switch wired 2.5 GbE minimum route.
+
+Changing one of these requires an explicit ADR update and human review, not an incidental story implementation.
+
+## Performance discipline
+
+GGUF performance is a hypothesis. Never write “GGUF is faster” without measurements.
+
+DGR-001 locks controlled benchmark lanes and thresholds. DGR-014 enforces the final distributed comparison.
+
+Always distinguish:
+
+- Weight quantization from activation/compute/KV dtype.
+- Runtime/kernel gains from quantization/model-fit gains.
+- Single-request latency from aggregate concurrency throughput.
+- Synthetic unit coverage from real distributed acceptance.
+
+Required metrics where applicable:
+
+```text
+TTFT
+prefill tokens/sec
+decode tokens/sec
+aggregate throughput
+p50/p95 latency
+seam bytes and latency
+queue and batch occupancy
+RSS and VRAM
+KV pressure
+output-quality drift
+failures and cleanup
+```
+
+Do not weaken or move performance thresholds after seeing implementation results.
+
+## Transport discipline
+
+Do not invent a raw TCP protocol, new WebSocket protocol, QUIC layer or bespoke binary control format.
+
+The `.proto` schema is the semantic contract. Direct transport uses gRPC. Existing relay infrastructure may carry the same serialized protobuf frames as opaque binary.
+
+Protocol requirements:
+
+- Schema/version negotiation.
+- Request/work ID.
+- Route Session ID and route epoch.
+- Exact Model Artifact/runtime recipe fingerprint.
+- Shard range and effective overlap-safe start.
+- Prefill/decode/release/cancel phases.
+- Position/token range and idempotency step.
+- Named tensors with shape, dtype, byte order and bounded fragments.
+- Compression/checksum.
+- Cache expectation/result.
+- Deadlines, cancellation, flow control and structured status.
+
+Avoid per-token channel creation and unbounded unary payloads. Generated code and build tooling must be reproducible; do not require manual copying.
+
+## Native runtime discipline
+
+Reuse llama.cpp for GGUF, mmap, kernels, architecture graphs, tokenizer, KV, sequences and heterogeneous backends.
+
+The project patch stack is limited to:
+
+- Range-aware tensor registration/loading.
+- Endpoint-specific embedding/final head ownership.
+- Architecture-defined intermediate input/output.
+- Intermediate output before final norm/head.
+- Layer-filtered KV and session mapping.
+
+Do not place Meshnet routing, transport, billing or authentication inside llama.cpp. Keep patches numbered, scoped, pinned and upstreamable.
+
+Dense Llama is first only as a cheap range/boundary fixture. GLM-5.2 is the explicit product adapter and alpha target immediately afterward. Qwen3/Qwen3-MoE is post-alpha. Do not generalize through unchecked tensor-name substitutions.
+
+## Existing code seams to inspect first

+## Dependency handoff rule
+
+For every dependency listed by Ralph:
+
+1. Confirm its `passes` state in `prd.json`.
+2. Read `.scratch/distributed-gguf-runtime/evidence/<DEPENDENCY-ID>/README.md`.
+3. Verify referenced source paths and commands still exist.
+4. Do not repeat completed work unless verification exposes a concrete defect.
+5. If dependency evidence is missing or contradictory, stop and repair the dependency instead of guessing.
+
+## Testing and hardware rules
+
+Default tests must be deterministic, GPU-free, model-download-free and API-credit-free.
+
+Real model tests require:
+
+```text
+MESHNET_ENABLE_REAL_INFERENCE_TESTS=1
+```
+
+On this machine:
+
+- Use `.venv-rocm` for real Radeon 8060S ROCm execution.
+- The default Python 3.14 `.venv` is unsuitable for real ROCm inference.
+- Resolve model storage through the machine-specific `.env.<hostname>` configuration.
+- Never download model artifacts under `/home`.
+- Real acceptance must exercise actual Tracker-routed CPU/GPU computation; synthetic workers are only unit tests.
+
+Record exact:
+
+- Model/revision and Artifact hash.
+- Quantization and runtime recipe.
+- Host/hardware/backend/driver.
+- Commands and environment names without secrets.
+- Raw output and metrics.
+- Whether the evidence is synthetic, local-real, or multi-machine-real.
+
+## Worktree and commit discipline
+
+This repository may contain pre-existing changes from research or another feature.
+
+- Inspect `git status` before editing.
+- Never reset, checkout over, stash, delete or reformat unrelated changes.
+- Stage only files belonging to the selected story.
+- Exclude `.ralph-tui`, iteration logs, caches, generated builds, FUSE artifacts and unrelated scratch work.
+- Keep one scoped commit per completed story when the supervising loop requests commits.
+- Do not modify `passes` for another story.
+
+## Mandatory finish/handoff sequence
+
+Before emitting `<promise>COMPLETE</promise>`:
+
+1. Verify every acceptance criterion with real command output or file evidence.
+2. Run story-specific gates and repository quality gates.
+3. Write `.scratch/distributed-gguf-runtime/evidence/<TASK-ID>/README.md` containing:
+   - Summary of changes.
+   - Exact files changed.
+   - Commands run and their real results.
+   - Performance/correctness evidence.
+   - Known limitations and deferred work.
+   - Compatibility or migration notes.
+   - Clear handoff for dependent stories.
+4. Save machine-readable evidence beside it when the story produces metrics or schemas.
+5. Update the source issue status to `done` only after all gates pass.
+6. Preserve failures honestly. Never fabricate model, benchmark, test or hardware output.

+# Performant concurrent distributed GGUF runtime
+
+Status: active benchmark-gated implementation program.
+
+## Objective
+
+Serve the exact pinned GLM-5.2 `UD-IQ1_S` artifact in `reasoning_effort=max` mode across consumer machines with useful measured performance. Dense Llama is a structural fixture; the real multi-node GLM target is the alpha release gate.

+# Performant Concurrent Distributed GGUF Architecture
+
+Status: current target architecture
+Last updated: 2026-07-13
+
+## Product invariant
+
+The system exists to serve high-quality models that exceed one consumer node's memory while retaining useful interactive speed and aggregate concurrency. A feature that only produces a distributed demo but is slower, globally serialized, or impossible to operate on consumer hardware is not complete.
+
+The alpha target is the exact pinned GLM-5.2 `UD-IQ1_S` artifact in `reasoning_effort=max` mode. Its target-specific architecture/resource/acceptance contract is [GLM-5.2-MAX-ALPHA-ROADMAP.md](GLM-5.2-MAX-ALPHA-ROADMAP.md). Dense Llama is a structural fixture, not the product target.
+
+## Existing control plane
+
+Meshnet remains the only public control plane:
+
+- Tracker registration, Coverage Map, route scoring and assignment.
+- Contiguous Shards and overlap-safe effective starts.
+- Stable Route Sessions and route epochs.
+- Local per-Shard Hot KV State in the reference backend.
+- Direct/relay transport, cancellation and backpressure.
+- Generation Telemetry, billing, validation and per-node attribution.
+- Model-agnostic capability admission.
+
+No external engine replaces these responsibilities.
+
+## Runtime topology
+
+```text
+OpenAI-compatible client
+        |
+Gateway / Tracker Node
+        |
+ordered Inference Route
+        |
+        +-- head Shard: tokenizer/embedding + early layers
+        |       local weights and Hot KV State
+        |
+        +-- middle Shard(s): architecture boundary + owned layers
+        |       local weights and Hot KV State
+        |
+        +-- tail Shard: final layers + norm/head/sampling
+                local weights and Hot KV State
+```
+
+Weights never move in the per-request hot path. Every node opens and verifies its local Model Artifact before becoming routable.
+
+## Primary execution substrate
+
+```text
+project-owned C++ Shard worker
+        |
+small exact-commit llama.cpp patch stack
+        |
+GGUF mmap, quantized kernels, architecture graphs,
+KV/sequence operations, CPU/CUDA/HIP/Vulkan/Metal backends
+```
+
+The patch stack adds only the missing local execution seam:
+
+1. Range-aware tensor registration/loading.
+2. Endpoint-specific embedding and final head ownership.
+3. Architecture-defined intermediate input.
+4. Architecture-defined pre-tail boundary output.
+5. Layer-filtered KV and external session mapping.
+
+The worker owns protocol translation and process lifecycle. llama.cpp never receives Tracker, relay, billing or volunteer-network code.
+
+## Shard data plane
+
+Use Protocol Buffers and gRPC over HTTP/2.
+
+### Service shape
+
+- Unary capability and health.
+- Bidirectional Route Session stream.
+- Explicit release and cancellation.
+- Metrics suitable for capability admission and route scoring.
+
+### Session stream
+
+One long-lived stream represents one Route Session Activation Seam. It amortizes connection setup and inherits HTTP/2 flow control. Every message carries enough identity to reject stale or incompatible work.
+
+```text
+schema version
+request/work id
+Route Session id
+route epoch
+Model Artifact hash
+runtime recipe fingerprint
+Shard begin/end and effective start
+prefill/decode/release/cancel phase
+position and token range
+idempotency step id
+cache expectation/result
+named tensor bundle
+compression/checksum
+```
+
+Prefill tensors are split into bounded ordered frames. Decode messages carry one-step architecture boundary bundles and remain small. DGR-006 amends the current v1 decode fast path—which carries only one `NamedTensor`—to carry a versioned `TensorBundle`, while preserving compact one-tensor encoding and explicit compatibility behavior.
+
+Tail completion is not inferred from an activation tensor name. The protocol exposes a typed logits and/or sampled-token result, and exact sampling parameters plus chat-template/reasoning mode are bound to request/runtime identity.
+
+Direct nodes use gRPC. Nodes requiring the existing relay carry the same protobuf frames as opaque binary through the relay session. This preserves one semantic protocol instead of maintaining separate direct and relay payload contracts.
+
+## Architecture boundary
+
+The public boundary is a versioned named-tensor bundle:
+
+```text
+bundle schema/version
+architecture adapter and boundary point
+named tensors
+per-tensor shape, dtype and byte order
+payload fragments
+compression/checksum
+```
+
+Dense Llama may use one residual tensor. Other adapters may require more. vLLM's Llama and Qwen3-MoE PP paths demonstrate a boundary with both `hidden_states` and `residual`; therefore the generic protocol must not assume one anonymous tensor.
+
+GLM-5.2 normally exchanges a 6,144-element hidden state. If a memory-balanced Shard boundary splits an IndexShare Full producer from Shared consumers, the bundle also carries the typed top-k index sideband. The planner prefers boundaries that keep an IndexShare ownership group local, but the protocol validates the sideband rather than assuming it never crosses a seam.
+
+Only the head owns token embedding. Only the tail owns final normalization, LM head and sampling. Middle Shards exchange the architecture-defined pre-tail boundary, not final normalized embeddings.
+
+## Hot KV State and concurrency
+
+```text
+(Route Session id, route epoch)
+       -> local llama sequence or bounded context
+       -> KV for owned layers only
+       -> lease, memory accounting and lifecycle
+```
+
+Required operations:
+
+- Prefill append.
+- Decode append.
+- Truncate after rejected speculative positions if later enabled.
+- Explicit release.
+- TTL/LRU eviction.
+- Cache-miss response.
+- Stale-epoch rejection.
+
+A node must not clear global KV on a new stream or serialize all requests behind one logical serving sequence.
+
+## Continuous batching
+
+Autoregressive dependencies remain sequential inside one Route Session. Aggregate throughput comes from batching compatible decode steps across active sessions:
+
+```text
+time 0: session A token 1 + session B token 8 + session C token 3
+          -> one llama batch for this Shard
+
+time 1: next ready positions from active sessions
+          -> next llama batch
+```
+
+The node scheduler:
+
+- Admits work against weight, KV, scratch and queue budgets.
+- Keeps per-session token positions and outputs separate.
+- Prevents long prefill from starving decode.
+- Applies bounded backpressure.
+- Reports active sessions, queue depth, batch occupancy, KV pressure and throughput.
+
+The initial deterministic gate is four concurrent sessions on a small model without cross-talk. Hardware-specific limits are measured and advertised through capability admission.
+
+## Parallelism boundaries
+
+| Mechanism | First-runtime use |
+|---|---|
+| Layer/pipeline parallelism | Public Inference Route across contiguous Shards |
+| Continuous batching | Inside every node across active Route Sessions |
+| Data parallelism | Multiple complete routes for independent requests |
+| Tensor parallelism | Deferred to a trusted composite node/managed cluster |
+| Expert parallelism | Deferred to a trusted composite node/managed cluster |
+| Disaggregated prefill | Deferred until core route performance passes |
+| Speculative decoding | Deferred optimization |
+
+Public WAN tensor/expert collectives are rejected for the first runtime because their per-layer communication and static rank assumptions conflict with heterogeneous volunteer nodes.
+
+## Optional providers
+
+### Transformers/safetensors
+
+Remains:
+
+- Correctness/reference backend.
+- Fallback for unsupported architectures.
+- Baseline for performance and output quality.
+
+### vLLM
+
+May run unmodified as a complete model or managed TP/PP/EP cluster represented as one logical provider. Its internal ranks are not independently routed or rewarded.
+
+Borrow only concepts such as named bundles, continuous batching, typed compatibility fingerprints, explicit transfer lifecycle and load telemetry.
+
+### Whole-model llama.cpp
+
+Provides a local proxy backend, correctness oracle and performance baseline. It is not the native distributed milestone.
+
+## Artifact and recipe compatibility
+
+A routable recipe identifies separately:
+
+- Source Model Artifact hash and optional derivative/slice hash.
+- Architecture and adapter version.
+- Tokenizer revision and vocabulary.
+- Weight quantization.
+- Activation interchange dtype/schema.
+- Backend compute dtype and backend implementation.
+- KV dtype/layout.
+- RoPE/context parameters.
+- llama.cpp commit and project patch version.
+- Shard range and endpoint ownership.
+
+Compatibility fails closed. Similar quantization labels or model names are not enough.
+
+## Admission and failure
+
+A recipe becomes routable only after a real local and distributed forward passes. Synthetic tests remain unit coverage.
+
+Alpha failure behavior:
+
+- Deadline or node loss cancels the Route Session.
+- Every node releases KV and queued buffers.
+- Uncertain mutations are not replayed silently.
+- Retry starts from token zero on a newly compatible route.
+- No cross-node KV import is trusted until a later signed/compatible snapshot protocol exists.
+
+## Performance release contract
+
+Before native development proceeds, compare the current Transformers/safetensors backend with whole-model llama.cpp under controlled model/hardware/quality lanes.
+
+Final release compares distributed GGUF with distributed safetensors using thresholds locked before seeing final results.
+
+Required measurements:
+
+- TTFT.
+- Prefill and decode tokens/sec.
+- Aggregate concurrency throughput.
+- p50/p95 latency.
+- Seam bytes and latency.
+- Queue/batch occupancy.
+- RSS, VRAM and KV pressure.
+- Output-quality drift.
+- Cancellation/failure cleanup.
+
+The GGUF path ships only if it is faster at acceptable quality or enables a larger otherwise-unroutable model at useful measured speed.
+
+## Implementation sequence
+
+1. Preserve completed DGR-001 performance and DGR-002 protocol contracts.
+2. DGR-017 locks exact GLM-5.2 Max artifact, resource, and alpha acceptance identity.
+3. Define exact recipe identity and pin one reproducible llama.cpp boundary.
+4. Run two lanes in parallel: DGR-018 establishes the whole-model `UD-IQ1_S` oracle on 224+ GiB usable memory, while DGR-005/DGR-006 implement range loading and named boundary parity with a cheap dense fixture.
+5. DGR-019 adds explicit GLM-5.2 MoE/MLA/DSA/IndexShare semantics after both lanes pass.
+6. Implement local KV; build and integrate the standalone worker.
+7. Pass local two-process and real two-physical-machine execution.
+8. Harden cancellation, node loss, restart, and cleanup required by alpha.
+9. DGR-020 executes the exact multi-node target and emits immutable `alpha` or `stop`.
+10. Post-alpha: continuous batching, final comparison, longer context, MTP, and package optimization.
+11. Prepare narrow upstream patches/tests; add Qwen as later architecture expansion.

+# Distributed GGUF Decision Framework
+
+> **Superseded for active implementation decisions.** The grill was resolved on 2026-07-13. Use [implementation-strategy.md](implementation-strategy.md), [architecture.md](architecture.md), [ADR-0020](ADR-0020-distributed-gguf-runtime.md), and [prd.json](prd.json). This file remains as historical decision rationale.
+
+This framework is for grilling open decisions. It keeps decisions tied to project vocabulary and implementation gates instead of vague "distributed inference" language.
+
+## Core Vocabulary
+
+Use the existing domain terms this way:
+
+- **Shard**: contiguous transformer layer range. This is the compute, routing, cache, and reward unit.
+- **Shard Swarm**: storage/download group for artifacts needed by a shard.
+- **Inference Route**: ordered node sequence that covers all layers for one request.
+- **Route Session**: one active request bound to one inference route and stable session id.
+- **Hot KV State**: live per-shard cache held by the route node during a route session.
+- **Prefix Snapshot**: persisted route-session state used for reuse or failover, not the hot decode path.
+- **Artifact Manifest**: canonical mapping from model artifacts to semantic model parts and runtime support.
+- **Generation Telemetry**: realtime progress for a route session, including phase and tokens/sec, independent of whether token deltas are streamed.
+
+## The Five Planes
+
+### 1. Control Plane
+
+Owner: Tracker.
+
+Responsibilities:
+
+- node registry
+- coverage map
+- route selection
+- rebalance directives
+- route-session creation
+- health and telemetry
+- client-visible Generation Telemetry
+- billing/audit records
+
+Must not do:
+
+- serve hot KV during every token
+- become the only place model artifacts can be fetched
+
+### 2. Artifact Plane
+
+Owner: Shard Swarms, local node storage, optional CDN/bootstrap mirrors.
+
+Responsibilities:
+
+- GGUF/safetensors/tokenizer download
+- content-addressed verification
+- local artifact inventory
+- artifact-to-layer mapping
+- cache eviction
+
+Must not do:
+
+- define execution order by file split alone
+- imply that a downloaded file chunk equals a Shard
+
+### 3. Execution Plane
+
+Owner: active Inference Route.
+
+Responsibilities:
+
+- chunked prefill
+- one-step decode
+- hidden-state transfer across activation seams
+- start-layer handling for overlapping shards
+- backpressure
+
+Must not do:
+
+- resend full context activations during decode
+- require cross-node tensor parallel all-reduce for public v1
+
+### 4. Session State Plane
+
+Owner: route nodes for hot KV; cache servers only for snapshots.
+
+Responsibilities:
+
+- per-shard local KV ownership
+- cache allocation and eviction
+- cache ABI compatibility
+- session close/release
+- optional prefix snapshots
+
+Must not do:
+
+- centralize hot KV in a remote service
+- let a replacement node continue from incompatible state
+
+### 5. Economics And Trust Plane
+
+Owner: tracker plus settlement/validation components.
+
+Responsibilities:
+
+- distinguish storage/seeding work from inference work
+- account for prefill and decode separately
+- record route participation
+- sample validation events
+- slash proven fraud
+
+Must not do:
+
+- pay a node for merely holding files as if it generated tokens
+- hide public-swarm privacy limits from clients
+
+## Hard Invariants
+
+These are the framework rules unless we deliberately write a new ADR:
+
+1. Public-network Shards are contiguous layer ranges.
+2. Hot KV State is local to the node serving that Shard in that Route Session.
+3. Artifact distribution and route execution are separate systems.
+4. Decode seam payload must be `O(hidden_size)`.
+5. Prefill may be `O(sequence_length * hidden_size)`, but only in bounded chunks.
+6. The tracker chooses routes; nodes do not negotiate route topology peer-to-peer.
+7. Model/backend-specific cache internals stay behind backend capability reports.
+8. PyTorch remains the correctness/reference backend while llama.cpp/GGUF becomes the performance backend.
+9. Streaming responses are preferred when feasible; Generation Telemetry is always required.
+
+## Resolved Gates
+
+### Gate 1: Public Shard Semantics
+
+Decision: public-network Shards are contiguous transformer layer ranges. Tensor-parallel or ring-style execution is allowed only inside one trusted node, one colocated pod, or a future composite node abstraction.
+
+Rationale:
+
+- Layer ranges match the existing `Shard`, `Coverage Map`, `Inference Route`, billing, and fraud vocabulary.
+- Public volunteer nodes should not require cross-node all-reduce or tight per-layer synchronization in v1.
+- Existing projects such as prima.cpp and Distributed Llama can still inform local-cluster/backend execution without becoming the public routing primitive.
+
+Consequences:
+
+- Artifact Manifests must map files/tensors to semantic layer ranges.
+- Route selection remains ordered layer coverage.
+- Rewards can be attributed to layer-range work.
+- Hot KV State is naturally owned by the node serving that layer range for the Route Session.
+
+### Gate 2: Hot KV Strategy
+
+Decision: v1 rejects centralized hot KV. Hot KV State is local to the node serving the relevant Shard in the active Route Session. Cache servers may store Prefix Snapshots for reuse, retry, or failover, but they are not in the per-token decode path.
+
+Rationale:
+
+- Decode is the tight loop; adding remote cache I/O there makes latency and bandwidth worse at the worst point.
+- Local KV naturally follows layer-range Shard ownership.
+- Centralized hot KV increases privacy exposure and creates consistency problems.
+- Prefix Snapshots preserve the useful part of central storage without making it mandatory for every generated token.
+
+Consequences:
+
+- Route Session must be sticky.
+- Failover is limited in alpha unless a compatible Prefix Snapshot exists.
+- Cache servers are optimization infrastructure, not required runtime infrastructure.
+- Route repair requires compatible model revision, layer range, backend cache ABI, and snapshot position.
+
+### Gate 3: First Runtime Proof
+
+Decision: prove distributed Route Session and Hot KV State semantics in the existing PyTorch route before modifying llama.cpp/GGUF.
+
+Rationale:
+
+- PyTorch exposes model internals and cache objects more directly, so it is the fastest way to validate the distributed protocol.
+- The current distributed PyTorch route already has the right high-level shape but disables cache and recomputes full prompts.
+- Fixing that path gives us a reference implementation for correctness tests, telemetry, session lifecycle, and wire protocol behavior.
+- llama.cpp/GGUF should receive a clear target ABI rather than becoming both the protocol experiment and the performance backend at once.
+
+Consequences:
+
+- Issue 02 precedes issue 05.
+- llama.cpp collaboration has a concrete target ABI.
+- The PyTorch route remains the architecture-coverage/reference backend even after GGUF becomes the preferred performance path.
+- The first success metric is eliminating full-prompt recompute in distributed decode.
+
+### Gate 3A: Client Feedback During Latency
+
+Decision: streaming responses are preferred when feasible, and realtime Generation Telemetry is required regardless of streaming support.
+
+Rationale:
+
+- The product optimizes for access to large capable models, so some latency is acceptable.
+- Users still need confidence that the route is alive and roughly how fast it is generating.
+- Streaming token deltas give the best user experience when the backend exposes them cleanly.
+- Tokens/sec remains useful during prefill, queueing, and any backend that cannot stream token deltas.
+
+Consequences:
+
+- The gateway should stream token deltas through an OpenAI-compatible response when possible.
+- The gateway must expose progress through SSE, WebSocket, or polling.
+- The final answer can be delivered after completion only as a fallback.
+- Telemetry must include route phase, generated token count, and rolling tokens/sec.
+- Non-streaming clients still need realtime telemetry.
+
+### Gate 4: llama.cpp Collaboration Shape
+
+Decision: target upstreamable `libllama`/ggml hooks instead of planning around a permanent fork.
+
+Rationale:
+
+- llama.cpp changes quickly across model support, quantization, kernels, and hardware backends.
+- A permanent fork would become expensive to maintain and would lag upstream improvements.
+- A short-lived prototype branch is acceptable if it proves the API and makes upstream collaboration concrete.
+- Keeping tracker/routing logic outside llama.cpp makes the upstream ask smaller and cleaner.
+
+Consequences:
+
+- Need a minimal reproducible localhost demo before asking upstream to carry the design.
+- Need to separate "what llama.cpp should expose" from "what our tracker does".
+- Desired upstream surface is layer-range execution, hidden-state boundary I/O, partial loading/introspection, and per-session KV ownership.
+- If upstream rejects the shape, we revisit whether to carry a narrow adapter fork or keep GGUF distributed execution as experimental.
+
+### Gate 5: First Model Target
+
+Decision: use a two-tier model target. Use a small, boring, llama.cpp-supported GGUF model for the first protocol smoke test. Use `deepseek-ai/DeepSeek-V4-Flash` as the first serious large-model target. Keep GLM-5.2 and Ornith as later support audits.
+
+Rationale:
+
+- The first protocol proof should isolate route/session/KV bugs from model-architecture bugs.
+- DeepSeek-V4-Flash is a strong first serious target because it is much smaller than 1.6T-class models while still being large enough to validate the product thesis.
+- DeepSeek-V4-Flash still has architecture-specific risks, so it should not be the first smoke test.
+- GLM-5.2 and Ornith remain valuable targets, but they add DSA/MLA/hybrid attention uncertainty.
+
+Consequences:
+
+- 128K cache accounting can be modeled now.
+- The first "real" target-model audit is DeepSeek-V4-Flash support in PyTorch, vLLM/SGLang, and any available GGUF/llama.cpp quantization path.
+- Production support waits for backend capability reports and exact cache ABI support.
+
+### Gate 6: Failure Semantics
+
+Decision: alpha fails Route Sessions on route-node loss instead of attempting automatic route repair.
+
+Rationale:
+
+- Route repair requires compatible Prefix Snapshots, cache ABI checks, replacement-node selection, billing correction, and client stream/error recovery.
+- Local Hot KV State means a replacement node cannot continue unless it has compatible state at the same position.
+- Fail-fast keeps the first implementation correct while the session/KV protocol is still being proven.
+
+Consequences:
+
+- Better observability and explicit errors are required.
+- Snapshotting becomes a later feature, not a blocker for first inference.
+- Generation Telemetry must report the last known phase and failure reason.
+- Client or gateway retry starts a new Route Session from scratch.
+
+### Gate 7: Transport
+
+Decision: keep binary HTTP for v1 activation transfer instead of jumping immediately to QUIC, WebRTC, or a custom transport.
+
+Rationale:
+
+- ADR-0008 already defines binary activation bodies with HTTP headers.
+- HTTP keeps the first implementation debuggable with the existing server stack and tooling.
+- The core risk is route/session/KV correctness, not transport optimization.
+- QUIC/WebRTC can be introduced later behind the same activation protocol once semantics are proven.
+
+Consequences:
+
+- Focus benchmark work on payload shape, chunking, and cache behavior first.
+- QUIC/WebRTC can be introduced as an optimization behind the same activation protocol.
+- v1 implementation can reuse the current HTTP routing, relay, and observability infrastructure.
+- Transport abstraction should be kept narrow enough that HTTP can be replaced later without changing backend cache semantics.
+
+## Grilling Progress
+
+Gates 1, 2, 3, 3A, 4, 5, 6, and 7 are resolved. The remaining work is to convert the resolved framework into implementation-ready issue briefs and prototype milestones.

+The snapshot digest covers every sorted relative path, resolved size, and file
+byte, so tokenizer/config drift is included. The BF16 GGUF was converted
+directly from the exact snapshot while preserving BF16 weights. Q4_K_M was
+quantized from an exact-revision F16 conversion with the pinned quantizer.
+Runtime validation recomputes every declared digest before model loading.
+
+## Real results
+
+All recipes completed every request with zero failures.
+
+| Metric | Transformers BF16 | llama.cpp BF16 | llama.cpp Q4_K_M |
+|---|---:|---:|---:|
+| Decode tok/s, c=1 | 40.8 | 98.5 | 207.7 |
+| Aggregate decode tok/s, c=4 | 46.5 | 222.8 | 195.7 |
+| TTFT p50, c=1 | 40.0 ms | 15.1 ms | 21.6 ms |
+| Peak resident memory, c=1 | 1.94 GB | 1.11 GB | 0.54 GB |
+| Artifact size | 1.00 GB | 0.99 GB | 0.40 GB |
+| Failures | 0 | 0 | 0 |
+
+Against the reference, the eligible Q4_K_M lane measured:
+
+- single-request decode speedup: **5.10×**;
+- concurrency-4 aggregate throughput speedup: **4.20×**;
+- resident-memory ratio: **0.279×**;
+- artifact-size ratio: **0.398×**.
+
+The near-lossless BF16 quality lane compared all three prompts but measured:
+
+- exact match: **0.3333** (v1 requires at least `0.90`);
+- mean text similarity: **0.9471** (v1 requires at least `0.97`).
+
+Tokenization and stopping were controlled: every runtime saw the same prompt
+token counts and reported 31 post-TTFT decode tokens. The v1 mismatch is a
+real greedy-output divergence on two prompts, not missing coverage or a
+text-length artifact. Its root cause remains undetermined; no post-contract
+logit-tie claim is acceptance evidence. Therefore `contract-evaluation.json`
+records:
+
+```text
+verdict: stop
+quality_lane_pass: false
+speed_benefit: true
+fit_benefit: true
+stop_condition_met: true
+```
+
+Thresholds were not changed after observing these results.
+
+## Post-contract parity and ROCm diagnostics
+
+`summarize-quality-parity.py` verifies and separates two signed sources. The CPU
+v1 row uses CPU kernels and a Transformers BF16 oracle; it remains at `0.3333`
+exact match with an unexplained divergence. The ROCm row uses a different plan,
+GPU kernels, and a Transformers float32 oracle. In that narrower diagnostic,
+the same BF16 GGUF artifact matches all three 32-token sequences exactly (`1.0`
+exact match and `1.0` similarity). No conversion corruption was observed in
+that three-sequence ROCm sample; this does not prove global conversion
+correctness or explain the CPU result.
+
+A separate HIP build at commit `e920c523` was compiled for `gfx1151` and
+measured `ROCm0: Radeon 8060S Graphics`; its `llama-server` SHA-256 is
+`b6bb4da687dbde86e243ba006cef05919b7b97255cd7e2371e1d451220aca139`.
+A signed `gpu-diagnostic` profile measured zero failures:
+
+| GPU metric | Transformers BF16 ROCm | llama.cpp Q4 ROCm | Q4 ratio |
+|---|---:|---:|---:|
+| Decode tok/s, c=1 | 81.12 | 251.25 | **3.10×** |
+| Aggregate decode tok/s, c=4 | 91.24 | 511.33 | **5.60×** |
+| TTFT p50, c=1 | 13.77 ms | 11.80 ms | **0.857×** |
+
+The GPU report is signed under the distinct
+`run_configured_gpu_diagnostic/v1` producer. The v1 evaluator rejects that
+producer even when its signature is valid. llama-server process VRAM remains
+unmeasured, so this diagnostic cannot replace or satisfy the immutable v1
+contract. Its signed backend detail records the measured `ROCm0: Radeon 8060S
+Graphics` device and `25/25` offloaded layers.
+
+## Implementation
+
+- `recipe_benchmark.py` provides the runtime-neutral measurement core, true
+  concurrency, continuous in-flight peak-memory sampling, percentile/throughput
+  aggregation, failures, and output drift.
+- `recipe_drivers.py` provides opt-in Transformers and llama-server drivers,
+  mounted-drive confinement, exact artifact/runtime verification, equal
+  device/thread budgets, greedy-only validation, measured host provenance, a
+  CPU-only v1 guard until process VRAM can be measured honestly, and a distinct
+  signed GPU diagnostic profile that the v1 evaluator cannot accept.
+- Peak RSS is runtime-scoped: Transformers reports growth above its pre-runtime
+  Python baseline, while llama.cpp reports its isolated server process tree.
+  Both are sampled continuously during in-flight requests.
+- TTFT uses each runtime's prompt/first-token compute boundary; end-to-end HTTP,
+  scheduling, and queue overhead remains in latency and `queue_wait_ms`.
+- The exact canonical plan SHA-256 locks prompts, model/revision, sampling,
+  output length, repeats, warmups, and concurrency. The evaluator also requires
+  equal prompt/decode token counts across recipes.
+- llama.cpp's `predicted_n` includes the first token while `predicted_ms` begins
+  after it; the driver subtracts that token so decode throughput matches the
+  Transformers inter-token convention.
+- `performance_contract.py` rejects wrong plans, unsigned or incorrectly signed
+  real evidence, wrong config/artifact/runtime/backend/host bindings, missing
+  recipes/concurrency, mixed model revisions, incomplete quality coverage, and
+  failed references.
+- Every non-synthetic report is Ed25519-signed over the complete canonical JSON,
+  including raw outcomes and metrics. The contract pins the public key and exact
+  config SHA-256; the private key remains outside Git at mode `0600`.
+- The signer fingerprint is independently anchored outside this evidence
+  directory in `../../trusted-evidence-signers.json` and checked by tests.
+- Quantized drift remains advisory. Only the near-lossless lane can satisfy the
+  quality gate, and only performance-fit recipes can earn speed/fit benefits.
+
+## Evidence files
+
+- `performance-contract.json` — immutable v1 thresholds and stop condition
+- `benchmark-config.json` — exact real-run plan, drivers, artifacts, and hashes
+- `results.json` — raw machine-readable per-request and aggregate evidence
+- `results.txt` — human-readable benchmark summary
+- `baseline.json` — distilled measurements for later comparison
+- `contract-evaluation.json` — fail-closed v1 verdict
+- `quality-parity-diagnosis.json` / `.md` — run/device-scoped signed-evidence summary
+- `summarize-quality-parity.py` — verifies both evidence chains and regenerates it
+- `gpu-diagnostic-config.json` — exact ROCm diagnostic artifacts and runtimes
+- `gpu-diagnostic-results.json` / `.txt` — signed GPU outcomes and summary
+- `commands.txt` — reproducible conversion, benchmark, evaluation, and test commands
+- `BLOCKED.md` — downstream stop-condition handoff
+- `known-unrelated-failure.md` — clean-base reproduction of the tracker race
+- `../../trusted-evidence-signers.json` — repository-reviewed signer fingerprint
+
+## Verification
+
+```text
+Targeted: 28 passed (5/5 consecutive focused runs)
+Latest full suite: 755 passed, 13 skipped
+Earlier full suite: 751 passed, 13 skipped
+Current cancellation retry matrix, DGR-001: 4/5 passed
+Earlier cancellation retry matrix, clean d904c40: 4/5 passed
+compileall: passed
+git diff --check: passed
+Evidence JSON parse/integrity checks: passed
+```
+
+The intermittent tracker cancellation race reproduced at the same rate on the
+clean base and is retained in `known-unrelated-failure.md`; the final full suite
+completed green. DGR-001 changes no tracker/proxy files.
+
+The earlier Ralph claim that the full suite was blocked by Protobuf 6.33.6 was
+invalid: it used Hermes Agent's internal venv. Verification above used the
+project `.venv`, which has the DGR-002-compatible runtime. Real inference used
+`.venv-rocm` Python 3.12.
+
+## Limitations and dependent-story handoff
+
+- The immutable contract result is a **0.5B CPU baseline**. The separate Radeon
+  diagnostic is real local GPU evidence, but neither result covers a large
+  model, distributed execution, network transport, or a native shard worker.
+- A separate `GGML_HIP=ON` llama.cpp build exists and produced GPU timings, but
+  llama-server process VRAM is not measurable by the current driver; GPU
+  memory/fit claims therefore remain ineligible for v1.
+- Absolute timings are developer-machine measurements; locked ratios and raw
+  artifacts are provided for reproducibility.
+- DGR-014 may consume v1 only with the exact plan/evidence requirements enforced
+  by `performance_contract.py`.
+- DGR-004 and later native-runtime work must not treat DGR-001 completion as a
+  promotion. V1 says `stop`; proceeding requires a human decision backed by a
+  separately versioned GPU/large-model contract or a diagnosed quality fix.

+# Observed pre-existing intermittent tracker race
+
+This file records an unrelated timing observation and its repeated reproduction;
+it is **not** a DGR-001 benchmark/contract failure.
+
+Test:
+
+```text
+tests/test_tracker_routing.py::test_tracker_dashboard_can_cancel_inflight_proxy
+```
+
+One earlier full-suite run produced:
+
+```text
+1 failed, 745 passed, 13 skipped
+```
+
+A five-run isolated retry matrix reproduced the same rate repeatedly:
+
+```text
+current DGR-001 branch: 4/5 passed, 1/5 failed
+clean d904c40:          4/5 passed, 1/5 failed
+```
+
+An earlier full-suite run on the signed-provenance DGR-001 state completed
+green:
+
+```text
+751 passed, 13 skipped
+```
+
+Two full-suite runs after adding the isolated GPU diagnostic profile each hit
+the same race and otherwise passed:
+
+```text
+1 failed, 750 passed, 13 skipped
+```
+
+The latest expanded hardening suite hit the same race and otherwise passed:
+
+```text
+1 failed, 754 passed, 13 skipped
+```
+
+The final hardened state subsequently completed a full green run:
+
+```text
+755 passed, 13 skipped
+```
+
+In each failure, the mock upstream's three-second release timeout completed the
+stream before the cancel POST, so the request was already absent and the cancel
+endpoint returned 404. No tracker/proxy file changed in DGR-001. The race is
+therefore timing-sensitive, pre-existing, and unrelated to the benchmark,
+provenance, or GPU-diagnostic code.

+# DGR-001 quality-parity evidence summary
+
+This summary is generated by `summarize-quality-parity.py` from signed reports.
+It contains no independent logit measurements or self-asserted verification flag.
+
+| Source | Device | Quality oracle | BF16 GGUF candidate | Exact | Similarity | Status |
+|---|---|---|---|---:|---:|---|
+| CPU v1 (`e4eedadf-22f6-4907-8990-985456961099`) | CPU | Transformers BF16 | llama.cpp BF16 | 0.3333 | 0.9471 | immutable `stop` |
+| ROCm diagnostic (`31bf44e7-ccd4-4277-84ac-c775dee65411`) | ROCm0 / Radeon 8060S | Transformers float32 | llama.cpp BF16 | 1.0000 | 1.0000 | diagnostic only |
+
+## Interpretation
+
+The CPU and ROCm rows use different plans, devices, kernels, and quality oracles.
+The CPU BF16 divergence remains unexplained and v1 remains `stop`. The signed
+ROCm report establishes the narrower fact that the same BF16 GGUF artifact
+matched the float32 oracle for all three GPU sequences with zero failures.
+Its signed backend detail records `ROCm0: Radeon 8060S Graphics` and measured
+`25/25` layer offload.
+
+No conversion corruption was observed in that three-sequence ROCm sample. This

+
+## Interpretation
+
+The CPU and ROCm rows use different plans, devices, kernels, and quality oracles.
+The CPU BF16 divergence remains unexplained and v1 remains `stop`. The signed
+ROCm report establishes the narrower fact that the same BF16 GGUF artifact
+matched the float32 oracle for all three GPU sequences with zero failures.
+Its signed backend detail records `ROCm0: Radeon 8060S Graphics` and measured
+`25/25` layer offload.
+
+No conversion corruption was observed in that three-sequence ROCm sample. This
+does not prove global conversion correctness and does not retroactively change
+or explain the CPU result. A future v2 should predeclare a float32 quality oracle
+separately from its BF16 performance reference and use a larger corpus.

+# DGR-002 — Adopt the versioned gRPC Shard protocol
+
+Status: **done**. Every acceptance criterion is met with real command output.
+Evidence class: **synthetic/unit** — this story defines a schema and proves both
+languages agree on it. No model, GPU, network peer or benchmark is involved, and
+none is claimed.
+
+## 1. Summary
+
+`packages/node/native/proto/shard_runtime.proto` is now the semantic contract for
+the native Shard data plane: Protocol Buffers over gRPC/HTTP2 (ADR-0020). Python
+and C++ both generate from it, and a shared committed conformance vector proves
+they encode it identically — byte for byte.
+
+Design decisions worth carrying forward:
+
+- **Everything gRPC gives you is *also* in the schema.** Deadline, cancellation,
+  identity and flow control are carried as fields, not left to HTTP/2 metadata,
+  because the existing relay carries these frames as **opaque binary**. A relayed
+  frame has no HTTP/2 context to inherit a deadline or a channel identity from.
+  If it is not in the schema, it does not survive the relay.
+- **Cancellation is both in-band and out-of-band.** `CancelSignal` rides the
+  stream; `Cancel` is also a unary RPC. A cancel that can only travel down a
+  stream that flow control has wedged is not a cancel.
+- **Checksums cover the uncompressed payload.** Compression is a per-hop
+  transport decision (reusing the existing `activation_compression` policies), so
+  a checksum over the compressed frame would be invalidated by a hop that merely
+  chose differently.
+- **Application-level flow-control credits, not just HTTP/2 windows.** HTTP/2
+  bounds *bytes in flight*; it does not bound how much *work* a worker has queued,
+  and a relayed frame gets no window at all. Credits bound queue occupancy and KV
+  pressure, and negotiation takes the strictest bound of either peer so a sender
+  cannot talk a worker into unbounded queues.
+
+## 2. Files changed
+
+New:
+
+| Path | What |
+|---|---|
+| `packages/node/native/proto/shard_runtime.proto` | The schema (sha256 `9e211660…`, see `protocol.json`) |
+| `packages/node/native/CMakeLists.txt` | C++ generation + build wiring + ctest |

+| `packages/node/meshnet_node/native_protocol/__init__.py` | Public Python surface |
+| `packages/node/meshnet_node/native_protocol/codec.py` | Bundle encode/decode, fragmentation, CRC32C, chunking, FC negotiation |
+| `packages/node/meshnet_node/native_protocol/conformance.py` | Canonical vectors shared by both languages |
+| `packages/node/meshnet_node/native_protocol/generated/` | Generated Python stubs (committed) |
+| `scripts/generate_native_protocol.py` | Python generation, with `--check` |
+| `scripts/generate_protocol_goldens.py` | Vector generation, with `--check` |
+| `scripts/bootstrap_native_toolchain.sh` | Builds protobuf C++ from source |
+| `tests/test_native_shard_protocol.py` | 45 Python tests |
+
+Modified:
+
+- `packages/node/pyproject.toml` — added runtime floors `grpcio>=1.82.1` and
+  `protobuf>=7.35.0`, matching the committed generated-code requirements; new
+  `proto` extra pinning `grpcio-tools==1.82.1`.
+- `packages/node/meshnet_node/activation_compression.py` — optional bounded zstd
+  output for untrusted protocol frames; existing callers remain compatible.
+- `packages/node/meshnet_node/native_protocol/__init__.py` — exports negotiated
+  bound constants and whole-session-message validation.
+
+The canonical PRD marks only DGR-002 passed. `git status` before this story was clean.

+The C++ lane was rebuilt from scratch by Ralph (`rm -rf build/native`) using only
+the documented commands, and reproduced the same result. During controller
+review the user explicitly chose not to repeat the destructive build-directory
+cleanup, so the independent controller relied on the recorded CMake/CTest run
+while reproducing every Python/generation/full-suite gate.
+
+### Controller review corrections
+
+Independent controller review found and fixed two classes of issue before
+integration:
+
+1. Generated stubs required gRPC 1.82.1 and Protobuf 7.35.0, while the initial
+   package metadata allowed much older runtimes that could fail at import time.
+2. Flow-control bounds were described but not enforced by the reference decoder.
+   Tensor declarations, shape rank/dimensions, fragment/tensor counts, fragments,
+   wire bodies, whole bundles, complete session messages (including envelope
+   overhead), and zstd window/output expansion are now fail-closed against the
+   negotiated/default bounds. Unspecified bundle versions, compression and
+   checksums are rejected rather than interpreted as valid data.
+3. Negotiated initial credits could exceed `max_inflight_chunks`; credits are now
+   capped by the settled in-flight limit.
+
+Controller results: protocol tests `45 passed`; protocol plus shared compression
+tests `51 passed`; final full suite `728 passed, 12 skipped`. A clean environment
+at the declared minimum gRPC/Protobuf runtime versions imported both generated
+stub modules and round-tripped the codec. Generation checks, `compileall`, static
+secret scan, and `git diff --check` all passed.
+
+### Full-suite note — a pre-existing flaky test
+
+`tests/test_tracker_routing.py::test_tracker_dashboard_can_cancel_inflight_proxy`
+is **flaky on a clean tree, independent of this story**. Reproduction, run
+*before any DGR-002 file existed* (working tree clean, `git status` empty):
+
+```
+pytest -q                                       -> 1 failed, 682 passed, 12 skipped
+  FAILED tests/test_tracker_routing.py::test_tracker_dashboard_can_cancel_inflight_proxy
+
+# same test, three consecutive isolated runs on the same clean tree:
+pytest -q tests/test_tracker_routing.py::test_tracker_dashboard_can_cancel_inflight_proxy
+  -> 1 passed in 1.76s
+  -> 1 failed in 4.39s
+  -> 1 passed in 1.10s
+```
+
+It is a timing race in proxy cancellation (a 3-second in-flight generation raced
+against the cancel assertion), not a deterministic failure, and it touches no code
+this story changes. One controller full-suite run reported exactly that one failure
+(`1 failed, 719 passed, 12 skipped`); three immediate isolated retries all passed
+in 1.11 seconds, and the final exact-code full suite was green (`728 passed,
+12 skipped`). It is flagged for whoever owns the tracker cancel path and is **not**
+fixed here, since silently touching another story's code is out of scope.
+
+## 4. Acceptance criteria
+
+| Criterion | Where it is proven |
+|---|---|
+| Schema for capability, health, session stream, release, cancellation | `shard_runtime.proto` `service ShardRuntime`; `test_service_exposes_capability_health_session_release_and_cancel` |
+| One long-lived bidi stream per Activation Seam, with deadlines, cancellation, flow control, structured errors | `rpc Session (stream) returns (stream)`; `test_session_is_one_long_lived_bidirectional_stream`; `Envelope.deadline_unix_nanos`, `CancelSignal` + unary `Cancel`, `FlowControl`, `ShardError` |
+| Bounded chunking for prefill; small decode fast path | `ChunkInfo` + `plan_prefill_chunks` (128-token bound, ADR-0008); `DecodeStep`; `test_prefill_is_split_into_bounded_token_aligned_chunks`, `test_decode_fast_path_is_much_smaller_than_a_full_envelope_chunk` |
+| Envelope carries schema version, work id, session id, epoch, fingerprint, range/effective start, phase, position, idempotency step, cache expectation, compression, checksum | `Envelope` + `NamedTensor`; `test_envelope_carries_every_field_the_protocol_promises` asserts against the **descriptor**, so deleting a field from the `.proto` fails the test |
+| Versioned named-tensor bundle: name, shape, dtype, byte order, fragments | `TensorBundle`/`NamedTensor`/`TensorFragment`; `test_named_tensor_bundle_is_versioned_and_fully_described`, `test_bundle_round_trips_multiple_named_tensors` |
+| Round-trip + compatibility tests in Python and C++ | 45 Python tests; C++ `ctest` 1/1; cross-language byte equality |
+| Targeted pytest passes | 45 passed |
+| `compileall packages tests` | exit 0 |
+| `git diff --check` | exit 0 |
+| Default tests deterministic, download-free, credit-free, GPU-free | Pure in-memory protobuf; no model, no network, no GPU |
+| Full deterministic pytest passes, or pre-existing failure recorded | Final exact-code run: 728 passed, 12 skipped; earlier sole flaky failure documented with clean-tree reproduction and 3/3 passing retries |
+
+## 5. How the cross-language claim is actually earned
+
+Two codecs that each round-trip their own output prove only that each is
+self-consistent. Instead:
+
+1. Python builds the canonical `SessionRequest` and commits its bytes.
+2. The C++ test parses **those** bytes, asserts every field, recomputes the CRC32C
+   **from the polynomial in independent C++ code**, reassembles the multi-fragment
+   tensor, and re-serializes to `cpp_roundtrip.binpb`.
+3. `test_cpp_and_python_agree_byte_for_byte` asserts that file equals the golden.
+
+Compatibility is tested in both languages: an unknown field from a newer peer
+survives a parse/serialize hop (a Shard forwards activations — silently stripping
+fields would corrupt a route it is merely a waypoint on), and a sparse message
+from an older peer parses to proto3 defaults.
+
+## 6. Limitations and deferred work
+
+- **gRPC C++ was not built or linked.** The C++ lane verifies the *schema* (message
+  types), not a running gRPC C++ server, because this machine has no gRPC C++ stack
+  and building it is a large dependency the conformance test does not need.
+  `CMakeLists.txt` already generates and exports `shard_runtime_grpc` when
+  `find_package(gRPC)` succeeds. **DGR-008 must install gRPC C++ and extend
+  `scripts/bootstrap_native_toolchain.sh`.**
+- **No wire is exercised.** No client, server, or stream lifecycle exists yet — no
+  deadline actually fires, no credit is actually consumed. This story defines and
+  proves the contract; DGR-008/DGR-009 implement it.
+- The protobuf C++ toolchain used here was installed to `/tmp/pbsrc/install` (ephemeral).
+  `scripts/bootstrap_native_toolchain.sh` reproduces it; prefer a durable prefix such
+  as `build/native-toolchain`.
+- `crc32c` has a pure-Python fallback (used here) and picks up `google_crc32c` when
+  present. The fallback is byte-exact but slow; a worker on the hot path should install
+  the native package. Not a correctness limitation.
+- Compression on the wire is zstd-or-none only, matching the existing seam.
+
+## 7. Compatibility and migration notes
+
+- **This does not change the existing HTTP activation wire.** `X-Meshnet-Wire` stays
+  at `2` and the legacy `/forward` path is untouched. The native protocol is a
+  *separate* contract with its own `SchemaVersion`, starting at 1. Nothing in this
+  story is on any live request path — it is additive.
+- Semantics are deliberately preserved from the existing ADRs so the two transports
+  mean the same thing: `effective_start_layer` (ADR-0012), `CacheMode`/`expected_past_len`
+  and `ERROR_CODE_CACHE_MISS` mapping to today's HTTP 409 `cache_miss` (ADR-0022),
+  bfloat16 boundary dtype and 128-token prefill chunks (ADR-0008), fingerprint/recipe
+  identity mirroring the capability report (ADR-0023).
+- `TensorFragment` field 5 (`uncompressed_size`) is **reserved**: it was removed
+  because `NamedTensor.total_bytes` is the single source of truth. Never recycle it —
+  a recycled field number is the one schema change peers cannot detect, because the
+  bytes still parse.
+- Committed Python stubs are guarded by `--check` in the test suite, so they cannot
+  drift from the schema unnoticed.
+
+## 8. Handoff to dependent stories
+
+- **DGR-003 (runtime recipe/fingerprint):** populate `Fingerprint`
+  (`model_artifact_digest`, `runtime_recipe_digest`, `recipe_id`, `recipe_version`,
+  `catalogue_version`). The mismatch outcome is already specified:
+  `ERROR_CODE_FINGERPRINT_MISMATCH`. Do not invent a second identity struct.
+- **DGR-005/006 (range loading, architecture boundary):** the boundary payload is a
+  **named bundle**, not a bare tensor — a boundary needing more than one tensor is
+  already representable. Execute `[effective_start_layer, end_layer)`, never from
+  `start_layer`.
+- **DGR-007 (concurrent sessions/KV):** isolate on `(route_session_id, route_epoch)`.
+  `CacheExpectation`/`CacheResult` and `ERROR_CODE_CACHE_MISS` are the contract; a
+  decode step whose `expected_past_len` does not match **must** miss, never fall back
+  to a silent stateless forward. `idempotency_step` means a retried step is
+  acknowledged (`Ack.duplicate`), not re-applied — re-applying advances the KV cache
+  twice and desynchronises the route.
+- **DGR-008 (C++ worker):** link `shard_runtime_grpc` from `CMakeLists.txt`; you must
+  first install gRPC C++ (see limitations). Honour `FlowControl` credits and the
+  `max_chunk_bytes` bound. Use `packages/node/meshnet_node/native_protocol/codec.py`
+  as the reference for fragment reassembly and checksum validation.
+- **DGR-009 (Meshnet integration):** the relay may carry these serialized frames as
+  opaque binary — that is exactly why deadline/cancel/identity are in-band. Do not add
+  a second control plane.
+- **Anyone editing the schema:** run both `--check` scripts; if a vector legitimately
+  changes, regenerate it and say so, because the C++ test asserts those exact bytes.

+# DGR-003 — exact Artifact and runtime recipe identity
+
+Evidence class: deterministic offline/unit. No model payload, GPU, external API,
+network node, or API credit is required or claimed.
+
+## Result — delayed-review repair, 2026-07-14
+
+DGR-003 defines and tests an exact, model-agnostic compatibility identity and
+connects it to DGR-002's gRPC `Fingerprint` plus tracker parsing, admission,
+route partitioning, and certification. It is **not complete**: the existing
+production doctor/backend path still emits the legacy capability report without
+constructing a `ShardIdentity` from authoritative loaded artifact/runtime state.
+No exact recipe is therefore claimed live or routable from that path; supplied
+exact identities remain dark until tracker-owned certification.
+
+A matching digest proves canonical consistency, **not node authenticity or real
+execution**. Tracker-owned certification of a fingerprint by a non-synthetic,
+complete, multi-node distributed forward is the execution trust boundary.
+
+## Implementation
+
+- `ArtifactIdentity` binds artifact ID/revision, exact content digest,
+  architecture/config digest, layer count, and optional derivative binding.
+- `DerivativeBinding` binds a split artifact to the exact source artifact digest
+  and its end-exclusive layer range. A Shard cannot advertise outside that range.
+- `RuntimeRecipe` keeps these canonical axes separate rather than hiding them in
+  a backend label:
+  - weight quantization;
+  - activation and compute dtypes;
+  - KV dtype and layout;
+  - tokenizer revision;
+  - architecture adapter;
+  - backend and runtime version;
+  - boundary and protocol schema versions;
+  - recipe ID/version and catalogue version.
+- `CompatibilityFingerprint` populates the existing DGR-002 Protobuf
+  `Fingerprint`; `check_session_open()` fails closed on schema, fingerprint,
+  advertised/effective range, non-empty route session, positive route epoch,
+  and (when supplied) exact tracker route-session/epoch assignment.
+- Node and tracker implementations independently canonicalize the declaration.
+  This is intentional: the tracker must not trust a digest copied from a node,
+  and future native/C++ workers also need an independent implementation. Their
+  behavior is pinned by `tests/data/recipe_fingerprint_vectors.json`.
+- Tracker admission cross-checks the exact identity against the capability
+  proof's model, range, recipe labels, backend, and weight quantization. Any
+  disagreement fails closed.
+- `TrackerServer` owns the sole live certification ledger and passes it through
+  direct and replicated registration paths. A known exact recipe is
+  `uncertified` and dark for user traffic until the same exact fingerprint is
+  certified. Restart fails closed; durable/cluster-wide certification events
+  require the later real-forward control path and are not claimed here.
+- Certification evidence is bound to the promoted fingerprint, requires at
+  least two distinct nodes, complete layer coverage, generated tokens, and
+  `synthetic=false`. Unknown or mismatched fingerprints cannot be promoted.
+

+
+A late review of dependency DGR-017 also found and fixed two genuine contract
+continuity defects during delayed DGR-003 review: v1 now has an independently
+trusted digest and recursively immutable parsed state. Those changes and tests
+are recorded in DGR-017 evidence rather than claimed as DGR-003 functionality.
+
+## Verification
+
+Exact commands and outcomes are in `commands.txt`.
+
+Observed final results:
+
+- DGR-003 identity + node/tracker capability suites: **126 passed**.
+- DGR-017 focused dependency repair suite: **99 passed**.
+- Tracker routing suite: **93 passed**.
+- First delayed-review integrated run: **898 passed, 13 skipped, 1 failed** on
+  the pre-existing tracker-cancellation race.
+- Final delayed-review integrated rerun: **899 passed, 13 skipped** in
+  **253.64s**; Hermes controller acceptance rerun: **899 passed, 13 skipped**
+  in **252.66s**.
+- `python -m compileall -q packages tests`: pass.
+- `git diff --check`: pass.
+- Ruff on the changed identity, capability, contract, and test modules: pass.
+- `server.py` has 8 pre-existing Ruff findings at both pushed baseline and the
+  current tree; DGR-003 added no finding.
+
+The first integrated full-suite run produced **871 passed, 13 skipped, 1 failed**
+on the known unrelated
+`test_tracker_dashboard_can_cancel_inflight_proxy` timing race. Its fixture
+completed after three seconds just before cancellation, so the cancel endpoint
+returned 404. In this delayed repair it again produced a 404 after the stream
+finished (first integrated run: **898 passed, 13 skipped, 1 failed**); three
+immediate isolated repeats passed before a fourth reproduced the same race.
+No cancellation-test code was changed. The final complete integrated rerun
+passed **899/899** tests.
+
+## Limitations
+
+- Certification state is process-local in this story. The same running tracker
+  reuses it across registrations, but durable/cluster-wide certification-event
+  persistence belongs with the later real distributed-forward control path.
+  Restart or failover therefore returns exact recipes to the safe dark state;
+  it never makes an unsupported recipe routable.
+- The node module has no certification ledger or admission policy; it holds only
+  identity construction and handshake validation. The Tracker is the sole
+  promotion authority.
+- **Completion blocker:** `doctor._validate_recipe()` calls
+  `build_capability_report()` without `identity=`, because the legacy
+  Transformers backend does not expose an immutable artifact-content pin and
+  full runtime recipe axes authoritative enough to build one. Adding a guessed
+  identity would weaken this contract. Production emission must be added with
+  the authoritative native worker/backend loading seam; until then the issue and
+  PRD deliberately remain incomplete.
+- This story proves identity and admission behavior with deterministic fixtures.
+  It does not claim a real GLM forward or hardware certification.
+
+## Compatibility
+
+- Capability report identity is additive. Legacy reports without the new block
+  retain ADR-0023's explicit compatibility-policy behavior.
+- Reports that opt into exact identity are held to it and fail closed on malformed,
+  inconsistent, unknown, dark, or mismatched declarations.
+- No new wire identity was invented; DGR-002's `Fingerprint` remains the gRPC
+  representation.
+
+## Handoff
+
+DGR-004 and native workers must build `ShardIdentity` from the actual immutable
+artifact pin, patch/runtime pin, tokenizer, numerical recipe, cache layout,
+schema versions, and owned range. At `SessionOpen`, compare its
+`CompatibilityFingerprint` and return DGR-002's
+`ERROR_CODE_FINGERPRINT_MISMATCH` on any mismatch.
+
+A digest match is not certification. Only tracker-recorded evidence from the
+same exact fingerprint and a real complete distributed forward can move that
+recipe out of dark status.
+
+## Native emission closure — 2026-07-14
+
+Status: **done**. DGR-004/DGR-005's native loaded-artifact seam now reaches the
+production capability-report path through `NativeWorkerBackendAdapter`.
+
+### Files changed
+
+- `packages/node/meshnet_node/native_backend.py` — immutable loaded-GGUF report,
+  immutable artifact and numerical pins, exact identity derivation, and the
+  SessionOpen boundary.
+- `packages/node/meshnet_node/doctor.py` — includes exact identity only for the
+  native adapter and derives all matching capability-proof fields from it.
+- `tests/test_native_identity_emission.py` — deterministic native report,
+  immutable-pin, SessionOpen, capability emission, legacy-dark, and
+  tracker-uncertified tests.
+- This issue, `prd.json`, and this evidence directory.
+
+### Correctness and trust boundary
+
+The native report carries the end-exclusive owned range, mapped/resident/
+registered bytes, GGUF architecture metadata digest, and layer count. The
+adapter constructs `ShardIdentity` only from that report plus immutable artifact
+pin, tokenizer revision, and numerical recipe inputs. It does not accept a
+caller-supplied shard range.
+
+`on_session_open()` calls `check_session_open()` before returning
+`SessionAccepted`, preserving fingerprint, schema, range, tracker-session, and
+epoch fail-closed behavior. The legacy Transformers backend is deliberately not
+an adapter and its doctor report remains identity-free.
+
+The tracker evaluates a self-consistent native report as `uncertified`: digest
+equality is canonical consistency, not node authenticity. Only its owned
+certification ledger can promote a real distributed forward.
+
+### Verification
+
+- Focused/adversarial DGR-003, node/tracker capability, doctor, and native
+  dependency suites: **171 passed, 1 skipped**.
+- Native protocol CMake configure/build plus CTest: **1/1 passed**.
+- `compileall`, Ruff, and `git diff --check`: pass.
+- Full deterministic suite: **902 passed, 13 skipped** (255.01s).
+
+No model payload, GPU, external API, network node, or real distributed forward
+was run or claimed. The standalone gRPC process remains DGR-008 work; this
+story supplies its exact native identity and fail-closed SessionOpen contract.

+# DGR-004 verification blocker — 2026-07-14
+
+## Verified state
+
+The pre-existing DGR-004 boundary is present and its lock data is internally
+consistent:
+
+- `scripts/llama_cpp_dependency.py inspect` reports pin
+  `e920c523e3b8a0163fe498af5bf90df35ff51d25`, one patch, no model downloads,
+  and no semantic certification.
+- The existing clean cached checkout at `build/dgr-004-final/source` is at the
+  locked commit/tree and contains only the expected staged patch changes.
+- The existing `llama-gguf-hash --help` smoke binary runs successfully.
+- `python -m compileall -q packages tests`, Ruff on the DGR-004 Python files,
+  and `git diff --check` pass.
+
+## Blocker
+
+The verification environment no longer contains the `.venv` recorded in
+`commands.txt`, nor a `cmake` executable on `PATH`. The available global
+pytest environment cannot import the native protocol because its protobuf
+runtime is 6.33.6 while the checked-in generated code requires 7.35.0. This
+causes both `tests/test_llama_cpp_dependency.py` and the native protocol suite
+to fail during the repository-wide autouse fixture setup, before their tests
+run.
+
+This prevents the required fresh focused test and native CTest verification.
+No DGR-004 completion state, commit, or push is claimed from this worktree.
+
+## Continuation
+
+1. Restore the project test environment used by the prior evidence (including
+   protobuf >= 7.35.0 and CMake), without changing DGR-004 source files.
+2. Run the exact focused test command from `commands.txt` and the clean
+   `reproduce` command using the local llama.cpp object cache.
+3. Re-run compileall, Ruff, diff check, and the deterministic full suite.
+4. Only then apply the supervising engine's commit policy and unblock DGR-005.
+
+## Dependency graph
+
+`DGR-004 verification -> DGR-005 range-aware GGUF ownership -> DGR-003 live
+ShardIdentity emission`. DGR-005 and DGR-003-emission were not modified.

+# DGR-004 — Reproducible pinned llama.cpp patch stack
+
+Status: **done**. This is reproducible native-build infrastructure evidence, not model execution evidence.
+
+## Delivered boundary
+
+- Pin: `ggml-org/llama.cpp` at `e920c523e3b8a0163fe498af5bf90df35ff51d25` (tree `6c91a11407a3a3fb160f5dac705f9c59718f54f1`).
+- Ordered patch: `0001-cmake-reserve-meshnet-patch-stack-abi-marker.patch`, SHA-256 `1454216c019c1cb7f78d1d836fe4054164fff1d498391013bcaf13cc2d328c75`.
+- The sole patch adds an interface-library CMake marker. It adds no model execution/loading, networking, Tracker, relay, gRPC, billing, or authentication code.
+- `scripts/llama_cpp_dependency.py` makes a fresh checkout, validates commit/tree/baseline blob, validates patch order/digests/context, applies the series, and verifies the exact resulting Git index tree. It rejects stale destinations, upstream drift, changed patches, untracked files, and local edits.
+
+## Build and smoke result
+
+The clean build cloned only the already-present exact Git object cache as a read-only source and did not trust its worktree. CMake 4.4.0 and GCC 15.2.1 built `llama-gguf-hash` with the locked Release/CPU flags in `UPSTREAM_LOCK.json`; `llama-gguf-hash --help` passed with no model download or load.
+
+llama.cpp tests are intentionally off for this small no-model smoke target, so no upstream CTest applies. Meshnet's focused native protocol suite passed independently. Exact results are in `commands.txt` and `results.json`.
+
+## License, compatibility, and handoff
+
+llama.cpp is MIT licensed. The materializer requires upstream `LICENSE`, preserves all upstream notices, and `THIRD_PARTY_NOTICES.md` requires including them in redistribution. No Mesh-LLM code or patch was adopted.
+
+The lock records the patched upstream blob and resulting patched tree. Pin updates must intentionally revise those values, the patch digest/order, toolchain metadata, and evidence.
+
+This stock/native build is **infrastructure evidence only**: not a standalone Meshnet worker (DGR-008), GLM semantic acceptance, DSA/IndexShare proof, numerical equivalence, performance success, model-fit evidence, or route certification. The stock dense-MLA fallback remains explicitly uncertified. DGR-001 CPU v1 remains `stop`; DGR-017 is a separate target contract. DGR-005 may consume this dense-Llama structural boundary; DGR-018/DGR-019 must prove GLM semantics.

+# DGR-005 decomposition — 2026-07-14
+
+## Verified starting point
+
+- The mandated environment is present: project Python 3.14.6, CMake 4.4.0,
+  and protobuf 7.35.1.
+- DGR-003's focused identity/capability tests and DGR-004's dependency tests
+  pass together: `95 passed`.
+- The DGR-004 materialized source at the pinned commit is available for source
+  inspection. It contains only the DGR-004 CMake-marker patch.
+
+## Why this chain cannot safely claim DGR-005 yet
+
+At the locked llama.cpp revision, `llama_model_base::load_tensors()`:
+
+1. sizes `layers` to `hparams.n_layer_all`;
+2. calls every architecture loader, which registers each architecture's layer
+   tensors; and
+3. runs a generic optional-scale pass over the full layer count before creating
+   mmap/backend buffers.
+
+Filtering names after this point does not meet the ownership contract: it
+leaves full-model model/graph assumptions and can make a middle Shard silently
+look valid while it lacks the endpoint and boundary semantics needed by the
+next story. A generic `blk.N.*` filter alone is also not an architecture
+adapter, which violates ADR-0020's fail-closed dense-Llama-first rule.
+
+## Required child slices
+
+1. **DGR-005A — native dense-Llama ownership API and loader**
+   - Add an explicit end-exclusive owned range to the project-owned native
+     interface and validate it against immutable GGUF layer metadata.
+   - Restrict registration, optional scales, allocation and mmap ranges to the
+     owned `blk.N.*` tensors.
+   - Record authoritative loaded start/end and mapped/resident byte counters
+     from the instantiated model, not command-line input.
+   - Add a deterministic synthetic dense-Llama GGUF fixture plus native tests
+     for head, middle and tail ranges.
+
+2. **DGR-005B — endpoint ownership and graph guard**
+   - Load token embeddings only for the head, and final norm/output head only
+     for the tail, including tied embeddings.
+   - Make the dense-Llama graph fail closed when an endpoint-required tensor is
+     absent; do not infer endpoint ownership from an empty pointer.
+   - Prove that split ranges map fewer bytes than the whole-model fixture and
+     that the loaded range report matches actual registered tensors.
+
+3. **DGR-003-emission follow-up**
+   - Expose the resulting immutable native loaded-artifact report to a native
+     worker/backend adapter.
+   - Construct `ShardIdentity` only from that report plus the immutable
+     artifact, tokenizer and numerical-recipe inputs. The legacy Transformers
+     doctor path must remain identity-free rather than fabricate a pin.
+   - Wire `check_session_open()` at the worker SessionOpen boundary; current
+     unit coverage already verifies its fail-closed fingerprint, range,
+     session and epoch behavior.
+

+# DGR-005 — dense-Llama range-aware GGUF ownership
+
+Evidence class: deterministic offline/unit (synthetic fixture) plus
+real-model integration (TinyLlama 1.1B, opt-in via MESHNET_ENABLE_REAL_INFERENCE_TESTS=1).
+
+## Result
+
+All six acceptance criteria pass:
+
+1. **Range-aware tensor ownership**: native C++ patch (`0002-dense-llama-owned-range-loader.patch`,
+   169 lines as merged — DGR-005A's original 365-line version was slimmed by DGR-005B)
+   adds `llama_model_params.meshnet_owned_layer_start/end`, `llama_meshnet_range_report`,
+   and restricts `blk.N.*` registration to the owned range.
+2. **Head/tail embedding loading**: head loads `token_embd.weight`; tail loads `output_norm`/`output`
+   (with tied-embedding dedup). Middle shards load zero endpoint tensors.
+3. **Mapped/resident memory scales with owned tensors**: proven with TinyLlama 1.1B Q4_K_M.
+4. **Targeted pytest tests**: `tests/test_llama_cpp_dependency.py` (3 tests — lock/patch
+   manifest consistency, offline dependency report, control-plane-code scan; re-verified
+   2026-07-14: `3 passed, 6 skipped` together with the opt-in integration file), native CTest
+   (`test-meshnet-range-ownership` synthetic fixture, added by the 0002 patch).
+5. **compileall, ruff, git diff --check, full pytest**: all pass.
+6. **Integration test**: `tests/test_gguf_distributed_load.py` (6/6, opt-in real model).

+## Limitations
+
+- Dense-Llama architecture only (LLM_ARCH_LLAMA). GLM/MoE/MLA is DGR-006+.
+- Graph-level endpoint assertions (`has_token_embeddings`, `has_output_head`) were
+  simplified to only `start_layer`/`end_layer`/`mapped_bytes`/`resident_bytes` in
+  the patch as merged. Full endpoint tracking is available via the integration test
+  by observing which tensors are registered per shard.
+- Loading the full `llama-simple` CLI requires reconfiguring with `-DLLAMA_BUILD_EXAMPLES=ON`.
+  The smoke-only build (`llama-gguf-hash`) is sufficient for patch verification.
+- TinyLlama 1.1B is a baseline dense-Llama architecture only.

+
+Status: complete deterministic/offline contract and dense-fixture evidence.
+
+## Result
+
+The native protocol now carries a versioned `TensorBundle` on the decode fast
+path. It includes explicit architecture and boundary-point metadata. Its legacy
+`NamedTensor` field remains a compact one-tensor encoding for certified dense
+boundaries; the writer deliberately selects it only for a one-tensor bundle and
+new readers wrap that representation into a bundle. The bundle is authoritative
+when present, allowing MoE/MLA sidebands without a second transport contract.
+
+`architecture_boundary.py` is the fail-closed adapter boundary. Dense head
+Shards accept token IDs and own embedding. Middle/tail Shards accept only a
+validated bundle. Dense, MoE, and MLA route through explicit adapters; unknown
+architectures are rejected. The dense F32 fixture proves whole-model versus
+two-range boundary parity without model downloads or real inference.
+
+Tail output is explicit in the schema: `TailResult` contains either logits or a
+sampled token and binds sampling parameters plus request ID, runtime recipe,
+chat template/version, reasoning mode, and architecture identity. The adapter
+builds and validates the serialized protobuf result before returning it.

+
+## Compatibility and limitations
+
+- Existing Nodes that send `DecodeStep.tensor` are accepted. New multi-tensor
+  Nodes require the versioned bundle and older Nodes safely preserve it as an
+  unknown field rather than interpreting it as a single tensor.
+- The committed C++ conformance vector covers the multi-tensor decode path.
+- The dense parity result is a deterministic F32 structural fixture, not real
+  GGUF inference or GLM certification. No real inference was run.
+- MoE and MLA adapters define and validate their sideband contracts but are not
+  architecture certifications. DGR-019 owns GLM MoE/MLA/DSA/IndexShare semantics.
+
+## Handoff
+
+DGR-007 can key its Hot KV state to the validated decoded bundle. DGR-008 can
+translate the generated `TailResult` and decode bundle over gRPC. DGR-019 must
+replace the generic MoE/MLA sideband names with exact certified GLM semantics.

+# DGR-017 — Lock the GLM-5.2 Max target and alpha contract
+
+Status: **done**. Every acceptance criterion is met with real command output.
+
+Evidence class: **real upstream metadata + deterministic arithmetic**. No weight
+payload was downloaded, no model was loaded, no GPU was used, and no benchmark was
+run — and none is claimed. This story makes the target *reviewable before* the
+216.7 GB download, which is exactly its job.
+
+## 1. Summary
+
+The alpha target is now pinned, planned, and sealed:
+
+- **Identity.** `zai-org/GLM-5.2` @ `b4734de4facf877f85769a911abafc5283eab3d9` and
+  `unsloth/GLM-5.2-GGUF` @ `abc55e72527792c6e77069c99b4cb7de16fa9f23`, quantization
+  `UD-IQ1_S`, six shards, 216,715,360,960 bytes, every shard's LFS SHA-256 resolved.
+- **Architecture.** The config/tokenizer/chat-template metadata the runtime cannot
+  shard without, hashed at the pinned revision.
+- **Resources.** A deterministic planner that counts unified memory once, applies the
+  `max(20% , 8 GiB)` reserve, and reports the arithmetic minimum and the recommended
+  node count as two different numbers.
+- **Contract.** The roadmap's section-5 acceptance matrix as a machine-readable,
+  digest-sealed document, locked before the target ever runs and cross-bound to the
+  exact manifest and architecture-snapshot digests.
+- **Upstream.** A refreshed llama.cpp/donor status report.
+
+Three findings are worth a reader's attention.
+
+**Every number in the roadmap reproduced from primary sources.** The 216,715,360,960
+byte total, the 201.832 GiB figure, the whole KV table (0.73 / 0.77 / 0.89 / 1.68 GiB
+at 16K, through 46.62 / 49.41 / 56.98 / 107.25 GiB at 1M), and the whole tier table
+(9 / 6 / 4 / 3 / 2 arithmetic minimum nodes) fall out of the exact config and the
+exact shard bytes. The roadmap was not approximating. The planner is written as a
+*reproduction* of those tables, so if the arithmetic ever stops matching, a test says
+which numbers moved.
+
+**The roadmap's "recommended" column is an imbalance factor of exactly 1.10.** Nodes
+= `ceil(total x 1.10 / budget)` yields 10 / 6 / 5 / 3 / 3 for the 32 / 48 / 64 / 96 /
+128 GiB tiers — precisely the roadmap's recommendations. That constant is now named
+(`PLACEMENT_IMBALANCE_FACTOR`) and documented as a placeholder for measured
+per-tensor placement, not a fudge factor to be tuned once results are in.
+
+**224 GiB aggregate does not actually fit.** Two 112 GiB nodes hit the 224 GiB
+"hard-fit floor" exactly, and still come up **23.5 GiB short** once each node honours
+its reserve. That is what makes 224 GiB an *experimental floor* rather than an
+envelope, and it is now a test, not a caveat in prose. Relatedly, the 2×128 and 4×64
+"fit probe" topologies fit with only **2.08 GiB of headroom across the entire route** —
+which is why they require measured placement evidence and are not the recommendation.
+
+## 2. Files changed
+
+New — runtime-loadable package (single source of truth):
+
+| Path | What |
+|---|---|
+| `packages/node/meshnet_node/glm_alpha/__init__.py` | Public surface |
+| `packages/node/meshnet_node/glm_alpha/manifest.py` | Target manifest + architecture snapshot; fail-closed identity |
+| `packages/node/meshnet_node/glm_alpha/planner.py` | Memory / KV / seam planner; unified-memory de-duplication |
+| `packages/node/meshnet_node/glm_alpha/contract.py` | Immutable, digest-sealed alpha acceptance contract |
+| `packages/node/meshnet_node/glm_alpha/data/target-manifest.json` | The six pinned shards, sizes, SHA-256, URLs, licenses |
+| `packages/node/meshnet_node/glm_alpha/data/architecture-snapshot.json` | Pinned architecture + config/template hashes |
+| `packages/node/meshnet_node/glm_alpha/data/alpha-contract.json` | Sealed acceptance thresholds (`aab23220…`) |
+| `scripts/refresh_glm_target_manifest.py` | Re-resolve/verify pins from upstream metadata (`--check` / `--write`) |
+| `tests/test_glm_alpha_target.py` | 97 deterministic offline tests (99 after the late-review repair — see §4a) |
+
+New — evidence:
+
+- `.scratch/distributed-gguf-runtime/evidence/DGR-017/README.md` (this file)
+- `.../commands.txt` — exact commands and real results
+- `.../resource-plan.json` — generated tier/route/seam/KV plan
+- `.../upstream-status.json` — refreshed llama.cpp and donor status
+
+Modified:
+
+- `.scratch/distributed-gguf-runtime/issues/17-...md` — `Status: done`
+- `.scratch/distributed-gguf-runtime/prd.json` — DGR-017 `passes: true` (this story only)
+- `.ralph-tui/progress.md` — learnings
+
+The data files live **in the package**, not in evidence, because the runtime must load
+them (DGR-018 verifies downloads against these digests; DGR-003 folds the manifest
+digest into the recipe fingerprint). Duplicating them into evidence would create two
+sources of truth that could drift.
+
+## 3. Acceptance criteria
+
+| Criterion | Where it is proven |
+|---|---|
+| Pin both repos by exact observed revision; `UD-IQ1_S` is the alpha quant | `target-manifest.json`; `test_manifest_pins_both_repositories_by_exact_revision` |
+| Six filenames, exact bytes, LFS SHA-256, aggregate GB/GiB, license, URLs, no payload download | HF `paths-info` API (LFS pointer metadata); `test_manifest_resolves_all_six_shards…`, `test_manifest_aggregate_bytes_are_exact_and_self_consistent` |
+| Snapshot + hash architecture-critical config/tokenizer/chat-template metadata | `architecture-snapshot.json`; `test_snapshot_captures_the_architecture_critical_metadata`, `test_snapshot_hashes_the_config_and_chat_template_bytes` |
+| Deterministic minimum-node calc from exact bytes, Q8_0 KV @16K/c1, imbalance, reserve | `planner.plan_topology`; `test_topology_planner_reproduces_the_published_tier_table` |
+| 224 GiB is a hard-fit floor, not an envelope; recommend 5×64 or 3×96/128 | `test_224_gib_aggregate_is_a_hard_fit_floor_not_an_operational_envelope`, `test_the_recommended_topologies_are_five_by_64_or_three_by_96_or_128` |
+| Unified memory counted once; additive RAM+VRAM rejected | `NodeMemory.from_host`; `test_adding_integrated_gpu_memory_to_system_ram_is_rejected`, `test_unified_memory_is_counted_once` |
+| 2.5 GbE minimum / 10 GbE recommended; serial latency modelled apart from bandwidth | `planner.plan_seams`; `test_2_5_gbe_is_the_alpha_minimum_and_10_gbe_is_recommended`, `test_serial_seam_latency_is_modelled_separately_from_bandwidth` |
+| Identity/semantic/target-run/performance/reliability/storage criteria locked before execution | `alpha-contract.json` (sealed, `locked_before_target_execution: true`); `test_the_contract_locks_every_roadmap_acceptance_section` |
+| Refresh upstream llama.cpp + donor status; no broad fork/scheduler | `upstream-status.json`; `adoption_state: none adopted` |
+| Tests reject changed revisions, missing shards, coordinated digest/config substitutions, inconsistent bytes, duplicate unified memory, malformed telemetry, and post-result threshold mutation | 97 tests; see §5 |
+| Targeted pytest passes | `97 passed` |
+| Installed wheel includes and loads all locked JSON resources | Real wheel build/install plus `load_locked_target()` outside the source tree |
+| `compileall packages tests` | exit 0 |
+| `git diff --check` | exit 0 |
+| Default tests deterministic, download-free, credit-free, GPU-free | Pure JSON + arithmetic; the only network code is an opt-in script excluded from the suite |
+| Full deterministic `pytest -q` | **852 passed, 13 skipped** on final rerun |
+
+## 4. Real results
+
+```
+scripts/refresh_glm_target_manifest.py --check  -> match upstream (exit 0)
+pytest -q tests/test_glm_alpha_target.py        -> 97 passed
+build + install wheel; load_locked_target()     -> INSTALLED_WHEEL_PASS

+pytest -q                                       -> 852 passed, 13 skipped (253.30s)
+```
+
+Controller review found and fixed four gaps before the commit was accepted:
+
+1. the initial wheel omitted `glm_alpha/data/*.json`, despite source-tree tests passing;
+2. the self-sealed contract did not bind the manifest/snapshot digests, so coordinated
+   shard-hash or architecture substitutions could be accepted;
+3. `--check` followed moving repository HEAD instead of validating immutable pins;
+4. non-finite resource telemetry could bypass ordinary range checks.
+
+Each failure now has either an adversarial regression test or a real installed-wheel /
+live-metadata gate. None of the provisional agent results were accepted on trust.
+
+The intermittent tracker cancellation race that DGR-001 and DGR-002 both recorded as
+flaky on a clean tree failed once in the final validation (`404` after the request
+completed), then passed **5/5** in isolation and passed in the integrated full-suite
+rerun above. This story touches no tracker code; the failed run is retained in
+`commands.txt` rather than hidden.
+
+### 4a. Late independent-review repair (2026-07-14)
+
+During delayed DGR-003 review, two contract-continuity defects were found and
+fixed here: v1 now has an independently trusted digest pinned in code
+(`test_resealing_a_mutated_v1_contract_is_rejected`) and parsed nested contract
+state is recursively immutable. This added two tests; the suite is now
+**99 passed** (`commands.txt` §7 records the exact runs). All "97" figures
+elsewhere in this README describe the suite at original completion.
+
+Planner output (`resource-plan.json`):
+
+| Route | Fits | Headroom |
+|---|---|---:|
+| 5×64 GiB unified (recommended) | yes | +53.28 GiB |
+| 3×96 GiB unified (recommended) | yes | +27.68 GiB |
+| 3×128 GiB unified (recommended) | yes | +104.48 GiB |
+| 4×64 GiB (fit probe) | yes | **+2.08 GiB** |
+| 2×128 GiB (fit probe) | yes | **+2.08 GiB** |
+| 2×112 GiB (= 224 GiB floor) | **no** | −23.52 GiB |
+| 3×64 GiB | no | −49.12 GiB |
+
+## 5. How the "no silent swap" claim is earned
+
+The story's whole purpose is to stop a later agent from changing the target after
+seeing a result. Each of those moves now has a test that names it:
+
+- swap the artifact → `test_a_changed_gguf_revision_is_rejected`
+- pin a branch instead of a commit → `test_a_branch_name_is_not_an_acceptable_revision_pin`
+- drop a shard → `test_a_missing_shard_is_rejected`
+- shrink a shard so it "fits" → `test_a_shard_size_edited_to_make_the_model_look_smaller_is_rejected`
+- change a valid-looking shard SHA without changing bytes → `test_coordinated_shard_hash_substitution_is_rejected_by_contract`
+- change internally consistent architecture metadata → `test_internally_consistent_architecture_substitution_is_rejected_by_contract`
+- take the bigger quant quietly → `test_swapping_in_a_different_quantization_is_rejected`
+- add iGPU "VRAM" to system RAM → `test_adding_integrated_gpu_memory_to_system_ram_is_rejected`
+- count one machine twice → `test_the_same_machine_counted_twice_in_a_route_is_rejected`
+- lower the speed floor → `test_lowering_the_speed_floor_after_seeing_a_result_is_rejected`
+- call a slow pass an alpha → `test_relabelling_a_speed_failure_as_a_pass_is_rejected`
+- admit the dense fallback → `test_admitting_the_dense_attention_fallback_after_the_fact_is_rejected`
+- shrink the reserve → `test_relaxing_the_per_node_reserve_after_the_fact_is_rejected`
+
+**Contract continuity is fail-closed.** The document’s `contract_sha256` detects
+accidental edits, and the approved v1 digest is pinned independently in code. A caller
+that changes a threshold and re-seals it under `glm-5.2-max-alpha/v1` is rejected by
+`test_resealing_a_mutated_v1_contract_is_rejected`; amendments require a new supported
+contract identity under human review. Parsed nested state is recursively immutable,
+so thresholds cannot change between validation and use; `to_dict()` returns an isolated
+copy rather than exposing the validated object.
+
+## 6. Upstream status — the gating risk for DGR-004/DGR-018
+
+Refreshed against live GitHub on 2026-07-13. One item **changed** since the roadmap:
+
+- **#24231 is now MERGED** (2026-07-11) — a generic `GGML_OP_LIGHTNING_INDEXER` exists.
+- #24770 MERGED (2026-06-20) — GLM-5.2 loads via a **dense-MLA compatibility path**.
+- **#25407 still OPEN** (updated today) — the real GLM DSA/IndexShare wiring.
+- #24730 still OPEN — the umbrella GLM-5.2 support request.
+
+**No released upstream llama.cpp performs native GLM-5.2 DSA + IndexShare today.** A
+stock pin taken now would load the artifact and emit text through the dense fallback —
+which the alpha contract explicitly refuses (`dense_attention_fallback_satisfies_alpha:
+false`). DGR-018 must therefore prove those paths are *active*, not that output appeared.
+
+Donor policy holds, and the evidence now supports it more strongly than before: PR
+#25407 is **12 files, +414/−7**. The semantics alpha needs are small enough to track
+and reproduce upstream. That is the argument against adopting Mesh-LLM's 261-patch
+fork — recorded as a donor (Apache-2.0, branch head `9bd18f15`, 2026-07-12), nothing
+adopted here.
+
+## 7. Limitations and deferred work
+
+- **No artifact was downloaded or loaded.** Sizes and SHA-256 come from Hugging Face
+  LFS pointer metadata. DGR-018 must verify the digests against the real files on
+  mounted storage before route admission. A matching size with a wrong hash is exactly
+  the failure this manifest exists to catch, and only a local verify can catch it.
+- **`PLACEMENT_IMBALANCE_FACTOR = 1.10` is a planning assumption, not a measurement.**
+  It reproduces the roadmap's recommendations, but the real per-node share depends on
+  exact tensor bytes (embeddings, output head, dense vs MoE layers, shared experts,
+  indexer tensors, quant block alignment). DGR-019 must replace it with measured
+  placement. Until then, arithmetic-minimum topologies (2×128, 4×64) stay fit probes.
+- **KV numbers are planning estimates, not admission truth.** The planner deliberately
+  budgets the *conservative* indexer layout (keys across all 78 layers, not just the 21
+  Full ones) so a route admitted here cannot be surprised by the implementation it
+  actually gets. The runtime must still report measured allocated/resident MLA and
+  indexer cache per shard.
+- **Peak scratch is unmodelled.** The reserve exists precisely because backend
+  workspaces and graph scratch are not predictable from the artifact; measured peak
+  must land inside the reserve, and the contract requires that evidence.
+- **Upstream is moving fast.** #25407 was updated the same day it was observed. Refresh
+  `upstream-status.json` before DGR-004 picks a llama.cpp pin. The manifest script's
+  `--check` deliberately validates the immutable Hugging Face pins, not moving HEAD.
+
+## 8. Compatibility and migration notes
+
+- Purely additive. No existing module, wire format, or test changed. Nothing in this
+  story is on a live request path.
+- `meshnet_node.glm_alpha` has **no heavy imports** — no torch, no transformers, no
+  network at import time — so a tracker or planner can read the target contract without
+  paying for a model runtime.
+- Re-pinning is deliberately awkward: `--write` follows current HEAD and leaves the
+  existing contract binding invalid until a new contract is reviewed and sealed.
+  `--check` uses revision-specific APIs and exits non-zero rather than healing any
+  integrity drift in the already locked target.
+
+## 9. Handoff to dependent stories
+
+**DGR-003 (recipe identity):** fold `TargetManifest.digest`
+(`0b6aed04479d204902bb64c0203f1a46cab26a47b378ecccf85237b63f6c1962`) and
+`ArchitectureSnapshot.digest` (`253fbd94…`) into the runtime recipe fingerprint. The
+GLM fields the roadmap asks you to add (DSA/IndexShare metadata, context max, expert
+counts) are already resolved in `architecture-snapshot.json` — read them, do not
+re-derive them by hand. Populate the DGR-002 `Fingerprint` message; do not invent a
+second identity struct.
+
+**DGR-004 (llama.cpp pin):** read `upstream-status.json` first. Any pin taken before
+#25407 merges gives you the dense-MLA fallback, which cannot satisfy alpha. Track
+#25407 (12 files) as a numbered patch; do not adopt the Mesh-LLM fork.
+
+**DGR-018 (whole-model oracle):** the six digests in `target-manifest.json` are what you
+verify the download against. Your host needs ≥224 GiB runtime-accessible memory — and
+note that 224 GiB is the *floor*, not a comfortable target (see §1). Prove DSA,
+IndexShare, shared expert, and the Max template are **active**; the contract's
+`require_rendered_reasoning_effort_marker` is `<|system|>Reasoning Effort: Max`. Assert
+the rendered marker, not the request field: the template's only non-max level is
+`'high'`, so *every other value — including an absent one — renders Max*, and "the
+request said max" proves nothing.
+
+**DGR-019 (GLM semantics):** the IndexShare split is **21 Full producer layers and 57
+Shared consumers**, in a `[full, full, full] + repeating [shared, shared, shared, full]`
+pattern. Prefer shard boundaries that keep an ownership group whole; the 8 KiB
+(2048 × int32) top-k sideband is the cost when you cannot. Replace
+`PLACEMENT_IMBALANCE_FACTOR` with measured per-tensor placement.
+
+**DGR-020 (alpha verdict):** load the target with `load_locked_target()`. It verifies
+the contract seal and cross-binds the manifest and architecture snapshot before
+returning them. Judge against
+`contract.threshold(section, key)` — an unlocked threshold raises rather than
+defaulting, so a criterion cannot be invented at read time. The verdict is `alpha` or
+`stop`; there is no third outcome, and a quality pass with a speed failure is `stop`.
+
+**Everyone:** unified system RAM and integrated-GPU memory are one pool. Build nodes
+with `NodeMemory.from_host(..., unified=True)` and it is impossible to write the
+double-count; pass a GPU size alongside `unified=True` and it raises rather than
+silently ignoring the argument.

+# DGR-018 — BLOCKED: no 256-GiB-class oracle host
+
+Recorded: 2026-07-14 (MAINT-003). Preflight scripts preserved at commit
+`a0f28b5` ("chore: preserve DGR-018 preflight scripts (postponed)").
+
+## Blocker
+
+DGR-018 requires a 256-GiB-class host with at least **224 GiB
+runtime-accessible memory** (the DGR-017 experimental hard-fit floor for the
+whole-model `UD-IQ1_S` oracle) and **250 GB free storage** on one filesystem
+outside `/home` (216.715 GB artifact plus resume/temp headroom). The available
+development host fails both gates, so the whole-model oracle cannot be
+established. Per the issue's finish contract, no smaller model may be
+substituted.
+
+DGR-019 (needs the DGR-018 oracle for parity certification) and DGR-020
+(needs DGR-018 and DGR-019, plus enough physical consumer nodes that no single
+node admits the whole recipe) are blocked transitively.
+
+## Exact preflight output

+
+## How to resume
+
+1. On a qualifying host, run `python scripts/glm_whole_model_preflight.py`
+   (optionally `--dest DIR`); it must exit 0 with `verdict: pass`.
+2. Download shards in the preflight's ordered plan; verify each with
+   `python scripts/verify_glm_shards.py` before the next transfer starts.
+3. Proceed with the DGR-018 issue
+   (`.scratch/distributed-gguf-runtime/issues/18-certify-whole-model-glm-5-2-runtime-semantics.md`).

+# Maintenance review handoff — distributed GGUF runtime
+
+Date: 2026-07-14
+Scope: close the maintenance review, preserve the hard blockers, and hand off the remaining implementation work to the next model.
+
+## What is complete
+
+- Completed stories are now recorded in `docs/issues/distributed-gguf-runtime/`.
+- The PRD and milestone docs were updated to reflect the closed set and the blocked set.
+- The DGR-018 preflight scripts were preserved at commit `a0f28b5`.
+- The current feature line has delivered DGR-001 through DGR-006 and DGR-017.
+
+## Hard / unsolved issues for later
+
+### 1) DGR-018 requires hardware we do not have
+
+DGR-018 is blocked because the whole-model GLM-5.2 UD-IQ1_S oracle requires:
+
+- a **256-GiB-class host**,
+- at least **224 GiB runtime-accessible memory**,
+- at least **250 GB free storage on one filesystem outside `/home`**.
+
+The current development host reports only **124.9 GiB MemTotal** and has no eligible filesystem with 250 GB free.
+The authoritative blocker evidence is in `evidence/DGR-018/BLOCKED.md` and `evidence/DGR-018/preflight.json`.
+
+### 2) DGR-019 and DGR-020 are transitively blocked
+
+- **DGR-019** needs the DGR-018 oracle for parity certification.
+- **DGR-020** needs DGR-018 and DGR-019, plus enough physical consumer nodes that no single node can admit the whole recipe.
+
+No smaller model may be substituted for these stories.
+
+### 3) The remainder of the graph stays blocked unless replanned
+
+The current graph makes **DGR-007 depend on DGR-019**, which means:
+
+- DGR-007 through DGR-016 are also blocked transitively.
+- Unblocking the dense pipeline without the 256-GiB host would require an explicit replanning decision to relax the DGR-007 → DGR-019 dependency.
+- That replanning decision has **not** been made.
+
+### 4) Maintenance-only tasks should stay separate from feature implementation
+
+The review uncovered that the codebase now has a clean closed-story split, but further work should avoid mixing:
+
+- maintenance cleanup,
+- blocked-hardware preparation,
+- and actual distributed GLM implementation.
+
+The next model should treat the maintenance pass as closed and only pick up real implementation work that is not hardware-blocked.
+
+## Recommended next move
+
+Use the next model to continue on the **non-blocked implementation queue** only.
+Priority candidates are whatever is still actionable without the GLM oracle host; if a story depends on DGR-018, keep it deferred.
