+A **flow** is a path through the skills. Most paths run along one **main flow**, and two **on-ramps** merge onto it. Everything else is standalone, or a vocabulary layer that runs underneath.
 
 ## The main flow: idea → ship
 
 The route most work travels. You have an idea and want it built.
 
-1. **`/grill-with-docs`** — sharpen the idea by interview. Start here when you **have a codebase**: it's stateful, retaining what it learns in `CONTEXT.md` and ADRs. (No codebase? Use `/grill-me` — see Standalone.)
+1. **`/grill-with-docs`** — sharpen the idea by interview. Start here when you **have a codebase**: it's stateful, retaining what it learns in `CONTEXT.md` and ADRs. (No codebase? Use `/grill-me` — see Standalone. Both run the same `/grilling` primitive; `grill-with-docs` is the one that leaves a paper trail.)
 2. **Branch — can you settle every question in conversation?** If a question needs a runnable answer (state, business logic, a UI you have to see), detour through a prototype, bridged by **`/handoff`** in both directions (see Crossing sessions):
    - **`/handoff`** out, then open a fresh session against that file,
    - **`/prototype`** to answer the question with throwaway code,
    - **`/handoff`** back what you learned, and reference it from the original idea thread.
 3. **Branch — is this a multi-session build?**
-   - **Yes** → **`/to-prd`** (turn the thread into a PRD) → **`/to-issues`** (split the PRD into independently-grabbable issues). Because the issues are independent, **clear context between each one**: start a fresh session per issue and kick off **`/implement`** by passing it the PRD and the single issue to work on.
+   - **Yes** → **`/to-spec`** (turn the thread into a spec), then **`/to-tickets`** to split it into tracer-bullet tickets, each declaring its **blocking edges**. On a local tracker that's one file per ticket under `.scratch/<feature>/issues/`, worked blockers-first by hand; on a real tracker the edges become native blocking links, so any ticket whose blockers are done can be grabbed — kick off **`/implement`** per ticket, **clearing context between each one**.
    - **No** → **`/implement`** right here, in the same context window.
 
+   Either way, **`/implement`** builds each issue by driving **`/tdd`** internally — one red-green slice at a time — then closes out by running **`/code-review`**, a two-axis review (Standards + Spec) of the diff, before committing. Reach for **`/tdd`** on its own when you just want to build a concrete behaviour test-first without a full spec, and **`/code-review`** on its own whenever you want to review a branch or PR against a fixed point.
+
 ### Context hygiene
 
-Keep steps 1–3 in **one unbroken context window** — don't compact or clear until after `/to-issues` — so the grilling, PRD, and issues all build on the same thinking. Each `/implement` then starts fresh, working from the issue.

+- **Something's broken** → **`/diagnosing-bugs`**. For the hard ones: the bug that resists a first glance, the intermittent flake, the regression that crept in between two known-good states. It refuses to theorise until it has a **tight feedback loop** — one command that already goes red on *this* bug — then fixes with a regression test. Its post-mortem hands off to **`/improve-codebase-architecture`** when the real finding is that there's no good seam to lock the bug down.
+
+- **A huge, foggy effort — a greenfield project or a huge feature build, too big for one session** → **`/wayfinder`**, the most cognitively demanding flow here. When the way from here to the destination isn't visible yet, it charts a **shared map** of **decision tickets** on the issue tracker and resolves them one at a time — producing **decisions, not deliverables** — until the fog is pushed back and the way is clear. Where **`/grill-with-docs`** sharpens an idea you can hold in one session, wayfinder is for the idea you can't — and it's slower and denser, so save it for exactly that, never a well-scoped feature.

-> Explainer: When the `triage` skill processes an incoming issue, it moves it through a state machine — needs evaluation, waiting on reporter, ready for an AFK agent to pick up, ready for a human, or won't fix. To do that, it needs to apply labels (or the equivalent in your issue tracker) that match strings *you've actually configured*. If your repo already uses different label names (e.g. `bug:triage` instead of `needs-triage`), map them here so the skill applies the right ones instead of creating duplicates.
+The defaults are the five canonical roles, each label string equal to its name: `needs-triage`, `needs-info`, `ready-for-agent`, `ready-for-human`, `wontfix`. On **yes**, write them as-is.

+description: Wire dependency-cruiser into a TypeScript repo so each package is a deep module — implementation hidden in subfolders, reachable only through its entry-point files. User-invoked.
+disable-model-invocation: true
+---
+
+# Setup TS Deep Modules
+
+Make every package in this repo a **deep module**: a lot of behaviour behind a small interface. A package's public surface is its **entry points** — the files at the package root — and everything in its subfolders is hidden. This skill installs [dependency-cruiser](https://github.com/sverweij/dependency-cruiser) and the rules that make the entry points the only way in, then proves the rules bite.
+
+For the vocabulary (deep module, interface, seam, depth), run the `/codebase-design` skill — use its language throughout.
+
+## The shape this enforces
+
+```
+src/packages/
+  <name>/
+    index.ts        ← an entry point (public). Import this from outside.
+    client.ts       ← another entry point. Packages may expose SEVERAL.
+    lib/            ← implementation: hidden from outside, free to import each other.
+    tests/          ← co-located tests + fixtures (a subfolder, so private).
+```
+
+The public surface is the package's **root files** — not one designated `index.ts`. By convention implementation lives in `lib/` and tests in `tests/`, giving every package the same two-folder shape. The rule itself is general, though: *anything* in *any* subfolder is private, so you never extend the config to add a folder.
+
+Four rules, all `error`:
+
+1. **Entry-point boundary** — code outside a package (app code or another package) may import only that package's entry points (its root files), never anything in its subfolders.
+2. **Intra-package freedom** — a package's own files import each other freely.
+3. **Tests through the entry points** — files under `<pkg>/tests/` may import any package's entry points and their own `tests/` fixtures, but never any package's subfolder internals (not even their own). Integration tests across packages are fine; deep imports are not.
+4. **No cycles** — no dependency cycles.
+
+**Entry points, not a barrel.** Because the public surface is *every* root file, a package can expose several small entry points (`index.ts`, `client.ts`, `server.ts`) instead of funnelling everything through one giant `index.ts`. Barrel files that re-export a whole subtree are discouraged — keep entry points small and hide implementation in subfolders.
+
+Layering (which packages may depend on which) is a *different* concern and is left as a commented stub in the config for this repo to fill in.
+
+## Steps
+
+### 1. Detect the environment
+
+- **Package manager** — `pnpm-lock.yaml` → pnpm, `yarn.lock` → yarn, `bun.lockb` → bun, else npm. Use it for every command below (`pnpm`/`yarn`/`npm run`/`bunx`).
+- **Packages root** — if `src/` exists use `src/packages`, else `packages`. Confirm the choice with the user if the repo already has a different obvious convention.
+- **Existing config** — check for a `.dependency-cruiser.*` file. If one exists, do **not** overwrite it: merge the four rules and the options in, and tell the user what you added.
+
+**Done when:** package manager, packages root, and existing-config status are all known.
+
+### 2. Install dependency-cruiser
+
+Install `dependency-cruiser` as a devDependency with the detected package manager.
+
+**Done when:** `dependency-cruiser` is in `devDependencies`.
+
+### 3. Write the config
+
+Copy [`dependency-cruiser.config.cjs`](./dependency-cruiser.config.cjs) to the repo root as `.dependency-cruiser.cjs`. Set `PACKAGES_ROOT` to the root detected in step 1. The rules are path-depth based and extension-agnostic, so nothing else needs adapting.
+
+**Done when:** `.dependency-cruiser.cjs` exists with the correct `PACKAGES_ROOT`, and the four forbidden rules are present.
+
+### 4. Wire it into the checks
+
+- Add a `lint:boundaries` script: `depcruise <packages-root>` (or `depcruise src`).
+- Fold it into the repo's umbrella check command — the one that already runs typecheck (e.g. a `check` / `ci` / `validate` script). Do **not** touch `tsconfig` or add path aliases.
+- If there is no umbrella script, add `lint:boundaries` and tell the user to include it in CI.
+
+**Done when:** `lint:boundaries` exists and runs as part of the same command as typecheck.
+
+### 5. Scaffold the example package
+
+Create a committed `<packages-root>/example/` as a copy-me template:
+
+- `index.ts` — an entry point. Export one function that delegates to an internal file (so the package is visibly *deep*, not a pass-through).
+- `lib/impl.ts` — an internal file in a **subfolder**, imported by `index.ts`, not reachable from outside.
+- `tests/example.test.ts` — imports **only** `../index` (an entry point), and asserts against the public function.
+
+Tell the user this is a starter template to copy or delete.
+
+**Done when:** the example package exists, exposes its behaviour through a root entry point, and hides `impl` in a subfolder.
+
+### 6. Prove the rules bite
+
+This is the completion criterion for the whole skill — a config that doesn't fail on a violation is worthless.
+
+1. Run `lint:boundaries`. It must **pass** on the clean example.
+2. Temporarily add a deep import to `tests/example.test.ts` (e.g. `import { thing } from "../lib/impl"`). Run `lint:boundaries` again — it must **fail** with `tests-through-entrypoints`.
+3. Revert the deep import. Run once more — it must **pass**.
+
+**Done when:** you have observed a pass, then a fail on the deep import, then a pass again. If step 2 does not fail, the rules are not wired correctly — fix before finishing.
+
+### 7. Document the convention
+
+Write a `README.md` **in the packages folder** (`<packages-root>/README.md`) — next to the packages it governs — covering: the `src/packages/<name>/` layout (entry points at the root, `lib/` for implementation, `tests/` for tests), "import only through a package's entry points (its root files)", and how to run `lint:boundaries`. **Discourage barrel files** explicitly — expose several small entry points instead of re-exporting a whole subtree through one index. Keep it to the copy-me snippet plus the four rules in one paragraph each.
+
+Then add a **context pointer** to it from the repo's agent-instructions file — `CLAUDE.md` if present, else `AGENTS.md` (create `AGENTS.md` if neither exists). One line is enough, e.g. `Packages are deep modules — see [src/packages/README.md](./src/packages/README.md) before adding or importing one.` This is what makes an agent discover the boundary rule instead of tripping over it.
+
+**Done when:** `<packages-root>/README.md` exists and discourages barrels, and the repo's `CLAUDE.md`/`AGENTS.md` links to it.
+
+## Notes
+
+- The config's `$1` back-references (dependency-cruiser's group matching) are what let a package reach its own internals while outsiders can't — don't flatten them into separate per-package rules.
+- Public vs private is decided by **depth**: a package's root files are entry points; anything in a subfolder is private. The conventional subfolders are `lib/` (implementation) and `tests/`, but the rule doesn't hardcode them — any subfolder is private, so a new folder never needs a config change. Adding an entry point is just adding a root file — no barrel.
+- Packages are **flat**: one tier of immediate children under the root. A package's internals may nest as deep as you like; a package may not contain another package.
+- Use `.cjs` (not `.js`) so the config's `module.exports` works even in `"type": "module"` repos.

 # Test-Driven Development
 
-## Philosophy
+TDD is the red → green loop. This skill is the reference that makes that loop produce tests worth keeping: what a good test is, where tests go, the anti-patterns, and the rules of the loop. Every section applies on every cycle — consult them before and during the loop, not after.
 
-**Core principle**: Tests should verify behavior through public interfaces, not implementation details. Code can change entirely; tests shouldn't.
+When exploring the codebase, read `CONTEXT.md` (if it exists) so test names and interface vocabulary match the project's domain language, and respect ADRs in the area you're touching.
 
-**Good tests** are integration-style: they exercise real code paths through public APIs. They describe _what_ the system does, not _how_ it does it. A good test reads like a specification - "user can checkout with valid cart" tells you exactly what capability exists. These tests survive refactors because they don't care about internal structure.
+## What a good test is
 
-**Bad tests** are coupled to implementation. They mock internal collaborators, test private methods, or verify through external means (like querying a database directly instead of using the interface). The warning sign: your test breaks when you refactor, but behavior hasn't changed. If you rename an internal function and tests fail, those tests were testing implementation, not behavior.
+Tests verify behavior through public interfaces, not implementation details. Code can change entirely; tests shouldn't. A good test reads like a specification — "user can checkout with valid cart" tells you exactly what capability exists — and survives refactors because it doesn't care about internal structure.
 
 See [tests.md](tests.md) for examples and [mocking.md](mocking.md) for mocking guidelines.
 
-## Anti-Pattern: Horizontal Slices
+## Seams — where tests go
 
-**DO NOT write all tests first, then all implementation.** This is "horizontal slicing" - treating RED as "write all tests" and GREEN as "write all code."
+A **seam** is the public boundary you test at: the interface where you observe behavior without reaching inside. Tests live at seams, never against internals.
 
-This produces **crap tests**:
+**Test only at pre-agreed seams.** Before writing any test, write down the seams under test and confirm them with the user. No test is written at an unconfirmed seam. You can't test everything — agreeing the seams up front is how testing effort lands on the critical paths and complex logic instead of every edge case.
 
-- Tests written in bulk test _imagined_ behavior, not _actual_ behavior
+Ask: "What's the public interface, and which seams should we test?"
-- You end up testing the _shape_ of things (data structures, function signatures) rather than user-facing behavior
-- Tests become insensitive to real changes - they pass when behavior breaks, fail when behavior is fine
-- You outrun your headlights, committing to test structure before understanding the implementation
 
-**Correct approach**: Vertical slices via tracer bullets. One test → one implementation → repeat. Each test responds to what you learned from the previous cycle. Because you just wrote the code, you know exactly what behavior matters and how to verify it.
+## Anti-patterns
 
-```
+- **Implementation-coupled** — mocks internal collaborators, tests private methods, or verifies through a side channel (querying the database instead of using the interface). The tell: the test breaks when you refactor but behavior hasn't changed.
-WRONG (horizontal):
+- **Tautological** — the assertion recomputes the expected value the way the code does (`expect(add(a, b)).toBe(a + b)`, a snapshot derived by hand the same way, a constant asserted equal to itself), so it passes by construction and can never disagree with the code. Expected values must come from an independent source of truth — a known-good literal, a worked example, the spec.
-  RED:   test1, test2, test3, test4, test5
+- **Horizontal slicing** — writing all tests first, then all implementation. Bulk tests verify _imagined_ behavior: you test the _shape_ of things rather than user-facing behavior, the tests go insensitive to real changes, and you commit to test structure before understanding the implementation. Work in **vertical slices** instead — one test → one implementation → repeat, each test a **tracer bullet** that responds to what the last cycle taught you.
-  GREEN: impl1, impl2, impl3, impl4, impl5
 
-RIGHT (vertical):
+## Rules of the loop
-  RED→GREEN: test1→impl1
-  RED→GREEN: test2→impl2
-  RED→GREEN: test3→impl3
-  ...
-```
 
-## Workflow
+- **Red before green.** Write the failing test first, then only enough code to pass it. Don't anticipate future tests or add speculative features.
-
+- **One slice at a time.** One seam, one test, one minimal implementation per cycle.
-### 1. Planning
+- **Refactoring is not part of the loop.** It belongs to the review stage (see the `code-review` skill), not the red → green implementation cycle.
-
-When exploring the codebase, read `CONTEXT.md` (if it exists) so that test names and interface vocabulary match the project's domain language, and respect ADRs in the area you're touching.
-
-Before writing any code:
-
-- [ ] Confirm with user what interface changes are needed
-- [ ] Confirm with user which behaviors to test (prioritize)
-- [ ] Identify opportunities for deep modules (small interface, deep implementation) — run the `/codebase-design` skill for the vocabulary and the testability checks
-- [ ] List the behaviors to test (not implementation steps)
-- [ ] Get user approval on the plan
-
-Ask: "What should the public interface look like? Which behaviors are most important to test?"
-
-**You can't test everything.** Confirm with the user exactly which behaviors matter most. Focus testing effort on critical paths and complex logic, not every possible edge case.
-
-### 2. Tracer Bullet
-
-Write ONE test that confirms ONE thing about the system:
-
-```
-RED:   Write test for first behavior → test fails
-GREEN: Write minimal code to pass → test passes
-```
-
-This is your tracer bullet - proves the path works end-to-end.
-
-### 3. Incremental Loop
-
-For each remaining behavior:
-
-```
-RED:   Write next test → fails
-GREEN: Minimal code to pass → passes
-```
-
-Rules:
-
-- One test at a time
-- Only enough code to pass current test
-- Don't anticipate future tests
-- Keep tests focused on observable behavior
-
-### 4. Refactor
-
-After all tests pass, look for [refactor candidates](refactoring.md):
-
-- [ ] Extract duplication
-- [ ] Deepen modules (move complexity behind simple interfaces)
-- [ ] Apply SOLID principles where natural
-- [ ] Consider what new code reveals about existing code
-- [ ] Run tests after each refactor step
-
-**Never refactor while RED.** Get to GREEN first.
-
-## Checklist Per Cycle
-
-```
-[ ] Test describes behavior, not implementation
-[ ] Test uses public interface only
-[ ] Test would survive internal refactor
-[ ] Code is minimal for this test
-[ ] No speculative features added
-```

+
+# To Tickets
+
+Break a plan, spec, or conversation into a set of **tickets** — tracer-bullet vertical slices, each declaring the tickets that **block** it.
+
+The issue tracker and triage label vocabulary should have been provided to you — run `/setup-matt-pocock-skills` if not.
+
+## Process
+
+### 1. Gather context
+
+Work from whatever is already in the conversation context. If the user passes a reference (a spec path, an issue number or URL) as an argument, fetch it and read its full body and comments.
+
+### 2. Explore the codebase (optional)
+
+If you have not already explored the codebase, do so to understand the current state of the code. Ticket titles and descriptions should use the project's domain glossary vocabulary, and respect ADRs in the area you're touching.
+
+Look for opportunities to prefactor the code to make the implementation easier. "Make the change easy, then make the easy change."
+
+### 3. Draft vertical slices
+
+Break the work into **tracer bullet** tickets.
+
+<vertical-slice-rules>
+
+- Each slice cuts a narrow but COMPLETE path through every layer (schema, API, UI, tests) — vertical, NOT a horizontal slice of one layer
+- A completed slice is demoable or verifiable on its own
+- Each slice is sized to fit in a single fresh context window
+- Any prefactoring should be done first
+
+</vertical-slice-rules>
+
+Give each ticket its **blocking edges** — the other tickets that must complete before it can start. A ticket with no blockers can start immediately.
+
+**Wide refactors are the exception to vertical slicing.** A **wide refactor** is one mechanical change — rename a column, retype a shared symbol — whose **blast radius** fans across the whole codebase, so a single edit breaks thousands of call sites at once and no vertical slice can land green. Don't force it into a tracer bullet; sequence it as **expand–contract**. First expand: add the new form beside the old so nothing breaks. Then migrate the call sites over in batches sized by blast radius (per package, per directory), each batch its own ticket blocked by the expand, keeping CI green batch to batch because the old form still exists. Finally contract: delete the old form once no caller remains, in a ticket blocked by every migrate batch. When even the batches can't stay green alone, keep the sequence but let them share an integration branch that all block a final integrate-and-verify ticket — green is promised only there.
+
+### 4. Quiz the user
+
+Present the proposed breakdown as a numbered list. For each ticket, show:
+
+- **Title**: short descriptive name
+- **Blocked by**: which other tickets (if any) must complete first
+- **What it delivers**: the end-to-end behaviour this ticket makes work
+
+Ask the user:
+
+- Does the granularity feel right? (too coarse / too fine)
+- Are the blocking edges correct — does each ticket only depend on tickets that genuinely gate it?
+- Should any tickets be merged or split further?
+
+Iterate until the user approves the breakdown.
+
+### 5. Publish the tickets to the configured tracker
+
+Publish the approved tickets. **How** depends on the tracker `/setup-matt-pocock-skills` configured — the tickets are the same either way, only the shape of the blocking edges changes:
+
+- **Local files** → write one file per ticket under `.scratch/<feature-slug>/issues/<NN>-<slug>.md`, numbered from `01` in dependency order (blockers first). Each file's "Blocked by" lists the numbers/titles it depends on. Use the per-ticket file template below — one ticket per file, never a single combined file.
+- **A real issue tracker (GitHub, Linear, …)** → publish one issue per ticket in dependency order (blockers first) so each ticket's blocking edges can reference real identifiers. Use the platform's native blocking / sub-issue relationship where it has one; otherwise set each ticket's "Blocked by" to the blocking issues. Apply the `ready-for-agent` triage label unless instructed otherwise — the tickets are agent-grabbable by construction.
+
+Work the **frontier**: any ticket whose blockers are all done. For a purely linear chain that means top to bottom.
+
+Do NOT close or modify any parent issue.
+
+<local-ticket-template>
+
+# <NN> — <Ticket title>
+
+**What to build:** the end-to-end behaviour this ticket makes work, from the user's perspective — not a layer-by-layer implementation list.
+
+**Blocked by:** the numbers/titles of the tickets that gate this one, or "None — can start immediately".
+
+**Status:** ready-for-agent
+

+<issue-template>

+
+## Blocked by
+
+- A reference to each blocking ticket, or "None — can start immediately".

+
+In either form, avoid specific file paths or code snippets — they go stale fast. Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it and note briefly that it came from a prototype. Trim to the decision-rich parts — not a working demo, just the important bits.
+
+Work the frontier one ticket at a time with `/implement`, clearing context between tickets.

+A loose idea has arrived — too big for one agent session, and wrapped in fog: the way from here to the **destination** isn't visible yet. Wayfinding is about finding that way, not charging at the destination. This skill charts the way as a **shared map** on the repo's issue tracker, then works its **decision tickets** — questions whose resolution is a decision, not slices of a build to execute — one at a time until the route is clear.
+
+The destination varies per effort, and naming it is the first act of charting — it shapes every ticket. It might be a spec to hand off and iterate on, a decision to lock before planning starts, or a change made in place like a data-structure migration. The map is domain-agnostic — engineering work, course content, whatever fits the shape.
+
+## Plan, don't do
+
+Wayfinder is **planning** by default: each ticket resolves a decision, and the map is done when the way is clear — nothing left to decide before someone goes and does the thing. The pull to just do the work is usually the signal you've reached the edge of the map and it's time to hand off. An effort can override this in its **Notes** — carrying execution into the map itself — but absent that, produce decisions, not deliverables.

+**Not yet specified** excludes what's already decided (Decisions so far), what's already a live ticket, and what's out of scope (the next section).
+
+## Out of scope
+
+Fog only ever gathers _toward_ the destination. The destination fixes the scope, so work beyond it is **out of scope** — it isn't fog, and it doesn't belong in **Not yet specified**. It gets its own **Out of scope** section on the map: work you've consciously ruled out of _this_ effort. Scope, not sharpness, lands it here.
+
+Out-of-scope work never graduates — the frontier stops at the destination — so it returns only if the destination is redrawn, and then as a fresh effort, not a resumption.
+
+Ruling something out of scope is a scoping act, not a step on the route. When a ticket that already exists turns out to sit past the destination — mis-scoped in while charting, or exposed by a resolution — **close it** (a closed ticket is unambiguously off the frontier) and leave one line in the **Out of scope** section: the gist plus why it's out of scope, linking the closed ticket. It stays out of **Decisions so far**, which records the route actually walked — a scope boundary isn't a step on it.

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.
+- **21 — Honest-noise calibration corpus** — `Status: ready-for-human` (engineering done 2026-07-06; blocked on human fleet calibration run before mainnet launch).
-- **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.
+- **23 — Dynamic HF-benchmarked pricing** — `Status: done` (see `23-dynamic-hf-pricing_completed.md`).
 
 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).
+**Ralph note:** `scripts/ralph_progress.py` tracks `docs/prd.json` (US-001…US-047; base 35/35 done, friends-test arc 36–47 open/in-progress). Alpha hardening uses `.scratch/alpha-hardening/prd.json` (AH-001…AH-023). Point Ralph at the prd.json for the branch you're running.
 
 **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.

+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.

 - 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 reserve-based split is expected: an 79 GB CPU node may be assigned layers 0-36, and a second node fills 37-39. Do not "fix" this by bypassing the 20% assignment reserve unless the shard-planning policy changes.
+- 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.

+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.
+- [ ] Dashboard call wall can show active requests from heartbeat data, not only tracker console terminal events.
+- [ ] Targeted telemetry tests pass.
+- [ ] Dynamic routing tests still pass, including GPU(0-21)+CPU(0-39) hybrid-route enumeration and traffic split behavior.
+- [ ] Full or non-integration suite result is recorded; unrelated pre-existing failures are named explicitly.
+- [ ] `.claude/settings.local.json` remains uncommitted unless intentionally approved.

+FLAT (17.21 → 19.28) — 2.68× overall, gap grows quadratically with length. Remaining
+acceptance item: re-measure on the live 2-node GPU topology (needs both machines).
+
+Scoped 2026-07-08 from a live two-machine distributed-inference debugging session (Qwen2.5-0.5B GPU+GPU pipeline, and Qwen3.6-35B-A3B mixed GPU/CPU). 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.

The ADR-0020 mixed-topology start_layer bug is fixed (518c259, e44abc9, 1ecc599); this is the next performance blocker in the same path. The distributed generation loop has NO KV cache at all: model_backend.py passes use_cache: False in every layer-forward call, and each autoregressive step re-encodes the entire prompt-so-far from scratch, re-running every layer on every node in the route for every generated token. Observed on a live 2-node Qwen2.5-0.5B GPU pipeline: tps decayed from 22.3 (at 235 output tokens) to 12.6 (at 449 tokens) within a single generation, the expected quadratic-cost signature. X-Meshnet-Session already exists on the wire but is minted fresh per token and only labels one activation transfer for chunk reassembly/logging, not keyed to any cached state. Build: (1) stable per-request session lifecycle instead of per-token, (2) per-node sharded cache keyed by session scoped to that node's own layer range only, (3) prefill-vs-decode split so post-prefill steps send only the newest token's activation, (4) cache abstraction that holds whatever use_cache=True returns per layer range (not K/V-shaped-only) because Qwen3.6's hybrid linear-attention layers cache recurrent conv/delta state, not standard K/V, (5) TTL+LRU eviction with an explicit cache-miss fallback to full re-prefill so restarts/route-changes degrade gracefully instead of corrupting output. MoE expert routing itself is layer-local and was already ruled out as the cause of the earlier Qwen3.6 garbage-output bug (that was the start_layer double-execution); the MoE angle that matters here is architecture-awareness so the cache design does not hardcode a K/V shape assumption that breaks on Qwen3.6's hybrid attention layers.\n\nSource issue has full subtask table and code refs.",

+# Runbook 04 — Honest-noise TOPLOC calibration (issue 21)
+
+**Status:** engineering complete; **operator action required** before production audit thresholds.
+
+**Blocks:** enabling calibrated TOPLOC thresholds on a mainnet / friends-test fleet (issue 21, ADR-0018).
+
+## When to run
+
+- Before first real-money traffic with audit enforcement enabled.
+- Again whenever the fleet’s **hardware mix** changes materially (new GPU generation, CPU-only nodes added, precision/recipe change per model).
+
+Alpha exception: with a **small hired-VPS-only** fleet, `gate_status.ready` may mean “covers every node we operate today” (`--toploc-calibration-gate-min-hardware-profiles 1`).
+
+## Prerequisites
+
+- Tracker running with billing + registry + `--toploc-calibration-db PATH` (or default under tracker cwd).
+- At least one **solo-capable** node per hardware profile you want in the corpus (full model coverage — partial shards are skipped).
+- Admin or validator credentials (`Authorization` header or validator service token per ADR-0017).
+- Reference validator can replay the fixed calibration prompt (same model/seed as dispatch uses).
+
+## Steps
+
+1. **Register the fleet** — all nodes you intend to pay on mainnet should be up, admitted (NCA when enabled), and solo-serving the calibration model.
+
+2. **Dispatch the job** (admin/validator only):
+
+   ```bash
+   curl -X POST "https://<tracker>/v1/calibration/toploc/run" \
+     -H "Authorization: Bearer <admin-or-validator-token>" \
+     -H "Content-Type: application/json" \
+     -d '{}'
+   ```
+
+   Partial-shard nodes appear under `skipped_partial_shard_node_ids`. Per-node failures appear under `skipped` with reasons.
+
+3. **Wait for completion** — watch tracker logs and node consoles until every solo-capable node has a row in the corpus.
+
+4. **Fetch results**:
+
+   ```bash
+   curl "https://<tracker>/v1/calibration/toploc/results" \
+     -H "Authorization: Bearer <admin-or-validator-token>"
+   ```
+
+   Record:
+   - `envelope` — p99 metrics + 20% safety margin (recommended tolerances).
+   - `gate_status.ready` and `gate_status.hardware_profiles`.
+   - `estimated_false_positive_rate` (in-sample sanity check only).
+
+5. **Write up thresholds** — paste envelope values into operator notes / issue 21 comment. Do **not** wire into production `ToplocAuditConfig` until you have reviewed FPR on this fleet.
+
+6. **Mark issue 21 done** — when corpus covers the launch fleet and thresholds are documented.
+
+## Two-wallet / minimal pilot variant
+
+If your “fleet” is one node machine + one client:
+
+- Run calibration against the **node** profile only (one hardware row is enough for `gate_status` with min profiles = 1).
+- Client wallet is irrelevant to calibration — it never serves inference.
+
+## Do not
+
+- Enable stricter production audit thresholds before this completes.
+- Reuse a corpus collected on devnet/mock hardware for a different mainnet GPU mix without re-running.
+
+## References
+
+- Issue: `.scratch/alpha-hardening/issues/21-honest-noise-calibration-corpus.md`
+- Code: `packages/tracker/meshnet_tracker/calibration.py`, `POST /v1/calibration/toploc/run`

+# Dashboard Test Runner
+
+Status: active
+
+## Goal
+Provide an opt-in, admin-only tracker Dashboard Testing tab that dynamically discovers pytest tests, runs fixed collected targets safely in background, and reports live logs/status.
+
+## Safety
+- Disabled unless tracker starts with an explicit flag.
+- Admin-only API/UI.
+- No arbitrary command/argument execution.
+- One active run.
+- Real inference stays separately environment-gated and excluded from default suites.
+
+## Operator workflow
+
+See [`docs/dev/dashboard-test-runner.md`](../../docs/dev/dashboard-test-runner.md)
+for launch configuration, default safe suites vs the gated real-inference suite,
+and required environment variables.
+
+See `prd.json` for executable Ralph user stories and acceptance criteria.

-# ADR-0020: Distributed GGUF/llama.cpp Runtime With Per-Shard Local KV
-
-Status: Proposed
-
-## Context
-
-The project currently uses PyTorch/Transformers for real model shards. That decision was captured in ADR-0001 because llama.cpp RPC at the time required the primary node to load the full model and distribute weights to workers, which conflicted with the desired model where nodes independently hold shards.
-
-We now want to serve very large open models, including GLM-5.2 and Ornith-class MoE models, over a torrent-like inference marketplace. CPU and mixed consumer hardware matter. LM Studio and llama.cpp demonstrate much better CPU/GGUF performance than our current PyTorch CPU path. The user also has a personal relationship with Georgi Gerganov, making upstream collaboration plausible.
-
-The current distributed PyTorch path is not yet production-grade: it recomputes the full growing sequence for every output token and disables KV cache inside manual layer calls. It sends hidden activations across seams, not KV, but those activations currently cover the full sequence every decode step.
-
-## Decision
-
-Adopt a distributed GGUF/llama.cpp runtime track while keeping PyTorch as the reference and fast-architecture backend.
-
-The runtime model is:
-
-- GGUF/model artifacts are distributed through torrent/content-addressed storage.
-- Nodes independently acquire and verify artifacts; no root node streams model weights to workers at session start.
-- Tracker chooses a sticky route covering all layers.
-- Each node owns hot KV/state for the layers it executes.
-- Prefill sends chunked activations through the route and builds local per-shard KV.
-- Decode sends one-step activations through the route and appends local KV at every shard.
-- Cache/CDN servers store cold artifacts and optional prefix/session snapshots, not hot per-token KV.
-- Context is capped at 128K for the first serious product path.
-
-## Technical Framework
-
-The design separates five planes:
-
-- **Control plane**: tracker registry, coverage map, route selection, session lifecycle, telemetry, billing, and audit.
-- **Artifact plane**: Shard Swarms, GGUF/safetensors/tokenizer files, manifests, hashes, and local node storage.
-- **Execution plane**: active Inference Route, chunked prefill, one-step decode, and hidden-state movement across activation seams.
-- **Session state plane**: per-shard Hot KV State on route nodes, plus optional Prefix Snapshots outside the hot loop.
-- **Economics/trust plane**: reward accounting, validation events, slash proofs, public/private route policy.

-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.
-
-The full challenge register is in [technical-challenges.md](./technical-challenges.md). The open decision gates are in [decision-framework.md](./decision-framework.md).
-
-Resolved gate:
-
-- Public-network Shards are layer ranges. Tensor-parallel/ring execution belongs inside a trusted node, colocated pod, or future composite node abstraction, not as the v1 public routing primitive.
-- Hot KV State is local to each route node for the Shard it serves. Cache servers may store Prefix Snapshots, but they are not part of the per-token decode path.
-- Distributed Route Session and Hot KV State semantics will be proven in the PyTorch route before llama.cpp/GGUF is extended for layer-boundary execution.
-- Streaming responses are preferred when feasible. Realtime Generation Telemetry is required so clients can see phase, generated token count, and tokens/sec even during prefill or non-streaming fallback paths.
-- llama.cpp/GGUF work targets upstreamable `libllama`/ggml hooks. A prototype fork is acceptable for exploration, but a permanent fork is not the plan.
-- Model targeting is two-tiered: use a small llama.cpp-supported GGUF model for the first protocol smoke test, then use `deepseek-ai/DeepSeek-V4-Flash` as the first serious large-model target. GLM-5.2 and Ornith remain later support audits.
-- Alpha fails Route Sessions on route-node loss instead of attempting automatic route repair. Repair requires compatible Prefix Snapshots and is a later capability.
-- v1 activation transfer stays on binary HTTP as defined by ADR-0008. QUIC/WebRTC/custom transport can be introduced later behind the same activation protocol.
-
-## Non-Goals
-
-- Do not put remote cache servers in the per-token hot KV path.
-- Do not require every node to hold the full model.
-- Do not fork llama.cpp long-term if upstream APIs can support the needed layer-boundary hooks.
-- Do not target GLM-5.2 or Ornith first; prove the route/KV protocol on a simpler well-supported GGUF model, then target DeepSeek-V4-Flash as the first serious large model.
-
-## Options Considered
-
-### A. Keep PyTorch-only distributed inference
-
-Pros:
-
-- Easy access to new Hugging Face architectures.
-- Transformers has mature single-process KV semantics.
-- Existing code already loads shards.
-
-Cons:
-
-- CPU inference is much slower than llama.cpp/GGUF.
-- Current distributed path bypasses `generate()` and disables cache.
-- Quantized GGUF ecosystem and LM Studio users are outside the runtime.
-
-### B. Use llama.cpp only as a full local model backend
-
-Pros:
-
-- Quick performance win for nodes with enough RAM/VRAM.
-- Minimal coordination with distributed protocol.
-
-Cons:
-
-- Does not unlock 397B/753B-class models for ordinary nodes.
-- Does not solve marketplace layer routing.
-
-### C. Distributed GGUF with per-shard local KV (chosen)
-
-Pros:
-
-- Aligns with torrent artifact distribution.
-- Avoids root streaming weights to workers.
-- Uses llama.cpp/GGUF performance where supported.
-- Compatible with public node rewards by layer/work contribution.
-- Scales KV memory by layer range.
-
-Cons:
-
-- Requires new runtime APIs around layer-boundary hidden states and per-session KV.
-- Requires model-specific cache metadata for DSA/MLA/hybrid attention.
-- Harder to debug than single-process `generate()`.
-
-### D. Centralized KV cache servers
-
-Pros:
-
-- Easier apparent session failover.
-- Central accounting of active cache.
-
-Cons:
-
-- Puts remote storage in the per-token hot path.
-- Adds bandwidth and latency at the worst possible point.
-- Creates consistency and privacy problems.
-
-Rejected for hot decode. Accepted only for cold prefix snapshots and failover checkpoints.
-
-## Consequences
-
-- ADR-0001 should eventually be amended: PyTorch remains valid, but llama.cpp/GGUF becomes a first-class backend.
-- The activation protocol must split prefill and decode explicitly.
-- Session IDs must be stable across the full request. The current fresh UUID-per-hop-call behavior must change.
-- Backends must report cache budget and cache compatibility.
-- Tracker route selection must include disk, memory pressure, cache warmth, and network latency.
-- Billing can be based on layer work, prefill tokens, decode tokens, and observed route participation.
-- Client UX should stream token deltas when feasible and must include route-session progress telemetry even when token deltas are not streamed.
-
-## Required Runtime Capabilities
-
-PyTorch path:
-
-- manual layer calls with `past_key_values` / model-specific cache object
-- per-shard session cache store
-- prefill chunk append
-- decode step append
-- stable session lifecycle endpoints
-
-llama.cpp/GGUF path:
-
-- full local GGUF serving
-- layer/tensor map extraction from GGUF
-- optional partial layer loading or mmap-backed selected execution
-- inbound hidden-state execution from arbitrary start layer
-- outbound hidden-state return at stop layer
-- per-session KV ownership for loaded layers
-- cache budget/compatibility introspection
-- GLM-5.2 DSA support when upstream/runtime supports it
-
-## Implementation Plan
-
-1. Add full-model `LlamaCppBackend` using `llama-server` or `libllama`.
-2. Implement distributed KV in the PyTorch path to prove semantics.
-3. Add session lifecycle and prefill/decode wire protocol.
-4. Add model artifact manifest and torrent seeding metadata.
-5. Prototype localhost two-process llama.cpp layer boundary execution.
-6. Generalize to network route.
-7. Bring in GLM-5.2/Ornith once backend support and cache accounting are verified.
-
-## Acceptance Criteria
-
-- A two-node localhost route can prefill once and decode N tokens without recomputing the full prompt.
-- Seam payload during decode is `O(hidden_size)`, not `O(sequence_length * hidden_size)`.
-- Per-node KV memory grows with owned layer count and context length.
-- Route loss during alpha fails cleanly with explicit reason.
-- Full local GGUF backend outperforms PyTorch CPU on a supported model.
-- Artifact manifest can identify exactly which files/chunks a node must seed for its advertised layer range.

-# PRD: Distributed GGUF Runtime
+# PRD: Performant Concurrent Distributed GGUF Runtime
 
-## Summary
+## Overview
 
-Build a distributed inference runtime that can serve large, quality-first open models by combining torrent-style model artifact distribution with sticky multi-node Inference Routes and per-shard local Hot KV State.
+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 first runtime proof uses the existing PyTorch route because it exposes model internals and cache semantics more directly. GGUF/llama.cpp becomes the performance path after the route-session contract is proven.
+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.
 
 ## Goals
 
-- Eliminate full-prompt recompute in distributed decode.
+- Execute one GGUF model across independently addressable contiguous Shards.
-- Keep decode activation seams proportional to `hidden_size`, not `context_length * hidden_size`.
+- Retain Hot KV State locally for each Shard and isolate concurrent Route Sessions.
-- Keep Hot KV State local to the node serving the relevant Shard.
+- Batch compatible decode steps across active sessions for aggregate throughput.
-- Stream token deltas when feasible and always expose Generation Telemetry.
+- Use consumer CPU, AMD, NVIDIA, Vulkan, Metal, and mixed routes only where a real certified forward passes.
-- Add a local full-model GGUF backend for immediate CPU performance wins.
+- Beat the current distributed safetensors route under a controlled performance contract or enable a larger otherwise-unroutable model at useful measured speed.
-- Define Model Artifact manifests so nodes can verify, seed, and advertise artifacts without depending on Hugging Face at request time.
+- Keep the critical path to Meshnet plus a small pinned llama.cpp fork and standalone C++ worker.
-- Prototype an upstreamable llama.cpp/libllama layer-boundary API.
+- Produce narrow upstream collaboration material for llama.cpp without placing Meshnet networking or economics inside upstream.
-- Use DeepSeek-V4-Flash as the first serious large-model target after smaller protocol smoke tests.
+
+## 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.
+
+## 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.
+- [ ] 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.
+
+## 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
 
-- No centralized hot KV cache in the per-token decode path.
+- Forking vLLM or importing its PagedAttention/Torch distributed runtime.
-- No automatic route repair in alpha.
+- Adopting Nakshatra, prima.cpp, llama-gguf, LiGGUF, or GPUStack as the control plane.
-- No permanent llama.cpp fork as the intended architecture.
+- Public WAN tensor/expert parallel collectives.
-- No GLM-5.2 or Ornith first; they remain follow-up support audits.
+- QUIC, WebRTC, or a custom socket protocol.
-- No transport rewrite to QUIC/WebRTC before route/session semantics are proven.
+- 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 dense Llama and Qwen3-family certification.
+- A marketing-scale model demo that bypasses parity, concurrency, admission, or performance gates.
 
-## Resolved Decisions
+## Success Metrics
 
-- Public-network Shards are contiguous transformer layer ranges.
+- A real model larger than one admitted node can execute across consumer machines when suitable hardware/artifacts are available.
-- Tensor/ring parallelism belongs inside one trusted node, one colocated pod, or a future composite node abstraction.
+- Four or more concurrent sessions complete without cross-talk; hardware-specific saturation is measured.
-- Hot KV State is local to route nodes; Prefix Snapshots are optional cold recovery/reuse artifacts.
+- Distributed GGUF passes the locked performance/fit contract against the existing safetensors route.
-- PyTorch distributed KV/session semantics are proven before llama.cpp distributed execution.
+- Worker and Tracker recover all resources after completion, cancellation, malformed input, and node failure.
-- Streaming responses are preferred; Generation Telemetry is mandatory.
+- The critical runtime remains Meshnet plus one standalone worker and a small auditable llama.cpp patch stack.
-- llama.cpp/GGUF work targets upstreamable `libllama`/ggml hooks.
-- Alpha fails Route Sessions on route-node loss.
-- v1 activation transfer stays on binary HTTP.
 
-## Target User Experience
+## Open Questions
 
-A client sends an OpenAI-compatible request. The Gateway or Tracker Node accepts the request, creates a Route Session, and streams token deltas when supported. The client receives live Generation Telemetry for route phase, prefill progress, generated token count, rolling tokens/sec, route health, and failure reason.
+- Exact benchmark model and quantization lanes are selected by DGR-001 from currently supported, legally redistributable artifacts.
-
+- Final hardware-specific concurrency and useful-speed thresholds are locked by measured baselines rather than guessed globally.
-If a route node drops in alpha, the request fails clearly. A retry starts a new Route Session from scratch.
+- Upstream llama.cpp acceptance is desirable but not a prerequisite for the first narrow pinned fork.
-
-## Runtime Shape
-
-```text
-client request
-  -> Gateway / Tracker Node creates Route Session
-  -> Tracker selects sticky Inference Route
-  -> prefill:
-       prompt chunks move through Shards
-       each node appends local Hot KV State
-  -> decode:
-       one-step activation moves through Shards
-       each node reads/appends local Hot KV State
-       tail returns token/logits
-  -> client receives streamed token deltas where possible
-  -> Generation Telemetry continues until complete or failed
-```
-
-## Milestones

-|---|---|---|
-| M1 — Session protocol proof | Stub route has stable Route Sessions, prefill/decode split, telemetry, and streaming contract | 01, 02, 03 |
-| M2 — PyTorch reference route | Distributed PyTorch decode uses local per-shard cache and stops full-prompt recompute | 04 |
-| M3 — Local GGUF performance path | Single-node GGUF backend serves through the node API and reports backend metadata | 05 |

-| M7 — First large model | DeepSeek-V4-Flash support path is audited and converted into follow-up runtime tasks | 09 |
-
-## Acceptance Criteria
-
-- A two-node route can prefill once and decode without resending full prompt activations.
-- Decode seam payload is one token/hidden-state step after prefill.
-- Route Session telemetry is visible before first token and during decode.
-- Streaming token deltas work where the backend supports them.
-- Route-node loss produces a structured alpha failure and does not attempt unsafe repair.
-- A local GGUF model can serve via the node API.
-- A Model Artifact manifest can prove which Shards a node can serve.
-- DeepSeek-V4-Flash has a written support recommendation: PyTorch, vLLM/SGLang, llama.cpp/GGUF, or blocked.

+# 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 `docs/adr/0024-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.
+
+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
+

+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`.
+
+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-family is first. Qwen3/Qwen3-MoE is a separate adapter after the dense release gate. Do not generalize through unchecked tensor-name substitutions.
+
+## Existing code seams to inspect first
+
+- `packages/node/meshnet_node/model_backend.py` — backend abstraction.
+- `packages/node/meshnet_node/torch_server.py` — reference ranged execution and session behavior.

+## 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.

-# Distributed GGUF runtime — planning index
+# Performant concurrent distributed GGUF runtime
 
-Status: draft scratch package.
+Status: active benchmark-gated implementation program.
 
-Goal: make the node network capable of serving large, high-quality open models by distributing GGUF/model artifacts over a torrent-style swarm while executing inference over a sticky multi-node route with per-shard local KV cache.
+## Objective
 
-This scratch supersedes the old assumption in [ADR-0001](../../docs/adr/0001-pytorch-over-llama-cpp.md) that llama.cpp is only a single-node leaf backend. That assumption was correct for the original llama.cpp RPC shape, but the target is now different: torrent-distributed GGUF artifacts plus an explicit route/KV protocol owned by this platform, ideally developed in collaboration with upstream llama.cpp.
+Serve top open models across consumer machines with useful performance and concurrent Route Sessions while keeping the runtime lean.

-## Decision Summary
+Transformers/safetensors remains the correctness baseline. vLLM remains an optional complete managed provider and a design donor; it is not forked into the public mesh.
 
-Adopt a hybrid runtime:
+## Planning artifacts
 
-- **Weights and artifacts**: distributed by torrent / content-addressed storage / optional CDN.
+- **[Mandatory Ralph context](RALPH-CONTEXT.md)** — read first in every fresh iteration
-- **Hot KV cache**: local to the node that owns the corresponding layer range.
+- [Task evidence contract](evidence/README.md)
-- **Prefix snapshots**: optionally persisted to cache servers for reuse, retry, and failover.
+- [Implementation strategy](implementation-strategy.md)
-- **Active route**: sticky for one request/session.
+- [Current architecture](architecture.md)
-- **Context cap**: 128K hard product limit for large models unless explicitly revised.
+- [PRD](PRD.md)
-- **Backends**: keep PyTorch for fast model-architecture coverage and validation; add llama.cpp/GGUF as the performance path for supported models.
+- [Ralph backlog](prd.json)
-- **Client feedback**: stream token deltas when feasible; always expose Generation Telemetry.
+- [ADR-0024](../../docs/adr/0024-distributed-gguf-runtime.md)
-- **First serious target model**: DeepSeek-V4-Flash after a smaller GGUF protocol smoke test.

-## What We Learned
+## Ralph execution
 
-- Our current full-model PyTorch path uses Transformers `generate()` and gets local KV cache.
+Use supervised one-story iterations for this high-risk runtime:
-- Our current distributed PyTorch path disables cache and recomputes the full growing sequence per token.
-- The seam today carries hidden activations, not KV cache; at 128K this becomes impossible for serious models if repeated every decode token.
-- The missing capability is not "send KV across the network"; it is **stable per-session local KV cache per shard**.
-- GGUF distribution is solved enough at the artifact layer, but GGUF/llama.cpp needs explicit layer-boundary execution APIs for our route model.
 
-## Recommended Order
+```bash
+ralph-tui run \
+  --prd .scratch/distributed-gguf-runtime/prd.json \
+  --agent claude --model opus \
+  --iterations 1 --no-tui --no-setup --verify
+```
 
-See [milestones.md](./milestones.md) for the full dependency map.
+Inspect the diff, run the story gates, and commit one verified story before the next iteration. Real-model stories require the explicit environment gate and mounted-drive model storage.

-- Can GGUF split metadata be made layer/tensor semantic enough for torrent placement and partial loading?
-- What is the minimum protocol needed for compressed KV formats such as GLM-5.2 DSA/MLA without exposing model-specific internals to the tracker?
-- How much reliability do we need in alpha: fail request on route loss, or support route repair with KV snapshots?

-## Product Stance
+Status: current target architecture
+Last updated: 2026-07-13
 
-The platform optimizes for access to high-quality models, not lowest latency. Latency is acceptable if the user can run models that are otherwise unavailable to them. The hard context limit for the first serious distributed runtime should be **128K tokens**. Longer context usually means the product is compensating for missing task decomposition, retrieval, or workspace summarization.
+## Product invariant
 
-## Current State
+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 current node has two materially different inference paths:
+## Existing control plane
 
-- **Full local PyTorch model**: calls Hugging Face `model.generate()`, so Transformers owns autoregressive decode and local KV cache.
+Meshnet remains the only public control plane:
-- **Distributed PyTorch route**: bypasses `model.generate()`, calls individual layers with `use_cache=False`, and recomputes the full growing sequence for every generated token.
 
-Current distributed data flow:
+- 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

-       head sends full activation [batch, sequence, hidden] to next node
+        |
-       middle nodes run their layers over all tokens
+        +-- head Shard: tokenizer/embedding + early layers
-       tail returns one decoded token string

+        |
+        +-- tail Shard: final layers + norm/head/sampling
+                local weights and Hot KV State
 ```
 
-This is correct for small demos but not viable for large models. For GLM-5.2, a single 128K seam activation is roughly:
+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
-128K tokens * hidden_size 6144 * 2 bytes ~= 1.5 GiB per hop
+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
 ```
 
-Sending that every output token is the bottleneck.
+The patch stack adds only the missing local execution seam:
 
-## Target State
+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.
 
-Target distributed data flow:
+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
-client request
+schema version
-  -> tracker selects route and pins session
+request/work id
-  -> head node creates session_id
+Route Session id
-  -> prefill:
+route epoch
-       prompt is chunked
+Model Artifact hash
-       each shard computes its layer range
+runtime recipe fingerprint
-       each shard appends local KV/state for its own layers
+Shard begin/end and effective start
-       activations cross only layer seams
+prefill/decode/release/cancel phase
-  -> decode loop:
+position and token range
-       head sends one new token / one-step hidden state
+idempotency step id
-       each shard reads local KV/state for session_id
+cache expectation/result
-       each shard appends one step to local KV/state
+named tensor bundle
-       only one-step activation crosses seams
+compression/checksum
-       tail returns logits/token
 ```
 
-The KV cache remains local to the node that computed it. It is not sent to the next node and not read from a remote cache server during every decode step.
+Prefill tensors are split into bounded ordered frames. Decode messages carry one-step architecture boundary bundles and remain small.
 
-## Client Feedback
+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.
 
-Streaming responses are desirable when the backend and client transport support them. The product should stream token deltas when possible, and it must always provide realtime Generation Telemetry while the route is working.
+## Architecture boundary
 
-The fallback behavior is a non-streaming final answer plus live telemetry. That fallback is acceptable for early route proofs or models/backends that cannot expose clean token deltas yet, but the preferred client experience is streamed output plus telemetry.
+The public boundary is a versioned named-tensor bundle:
-
-Minimum client-visible telemetry:
-
-- route/session accepted
-- selected model and quantization
-- prefill phase started/completed
-- decode phase started
-- generated token count
-- rolling tokens per second
-- route health or retry/failure reason
-- estimated billing units when available
-
-Implementation options:
-
-- Server-Sent Events or WebSocket for realtime progress
-- polling endpoint for simple clients
-- OpenAI-compatible streaming for clients that require token deltas
-
-This means "no token streaming" is acceptable only as a fallback. "Silent wait for minutes" is not acceptable.
-
-## Artifact Plane
-
-Artifact distribution is separate from execution.
 
 ```text
-model publisher
+bundle schema/version
-  -> produces model manifest
+architecture adapter and boundary point
-  -> creates GGUF / safetensors / tokenizer artifacts
+named tensors
-  -> content-addresses every file/chunk
+per-tensor shape, dtype and byte order
-  -> publishes torrent/magnet + HTTP fallback metadata
+payload fragments
-
+compression/checksum
-node
-  -> chooses model/layer range
-  -> downloads needed files/chunks
-  -> verifies hash
-  -> advertises availability to tracker
 ```
 
-Required manifest fields:
+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.
 
-- model id and version
+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.
-- upstream source repo and revision
-- license
-- architecture name
-- tokenizer files and hashes
-- quantization
-- tensor-to-layer map
-- file/chunk hashes
-- optional GGUF split files
-- supported runtime backends
-- context cap
-- KV/cache format descriptor
 
-## Execution Plane
+## Hot KV State and concurrency
-
-The tracker selects routes using layer coverage and observed performance:
 
 ```text
-route = [
+(Route Session id, route epoch)
-  head node: embeddings + layers 0..k
+       -> local llama sequence or bounded context
-  middle nodes: contiguous layer ranges
+       -> KV for owned layers only
-  tail node: final layers + norm + lm_head
+       -> lease, memory accounting and lifecycle
-]
 ```
 
-Route selection inputs:
+Required operations:
 
-- model id/version/quantization
+- Prefill append.
-- layer coverage
+- Decode append.
-- node hardware
+- Truncate after rejected speculative positions if later enabled.
-- measured prefill throughput
+- Explicit release.
-- measured decode throughput
+- TTL/LRU eviction.
-- queue depth
+- Cache-miss response.
-- latency to neighboring nodes
+- Stale-epoch rejection.
-- cache warmth for the requested prefix/session
-- reliability/reputation
 
-The route is sticky for the request/session. A new route means either a fresh prefill or restoring compatible KV snapshots.
+A node must not clear global KV on a new stream or serialize all requests behind one logical serving sequence.
 
-## KV Cache Ownership
+## Continuous batching
 
-KV/state ownership is by layer range:
+Autoregressive dependencies remain sequential inside one Route Session. Aggregate throughput comes from batching compatible decode steps across active sessions:
 
 ```text
-session_id = request scoped id

+- Prevents long prefill from starving decode.
+- Applies bounded backpressure.
+- Reports active sessions, queue depth, batch occupancy, KV pressure and throughput.
 
-- prompt-prefix snapshots
+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.
-- session checkpoints for retry
-- cold reusable context blocks
-- audit samples
 
-Cache servers must not be in the per-token hot loop unless colocated with the compute node.

-## GGUF / llama.cpp Integration
+- 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.
 
-The target llama.cpp integration needs more than `llama-server`.
+## Performance release contract
 
-Required capabilities:
+Before native development proceeds, compare the current Transformers/safetensors backend with whole-model llama.cpp under controlled model/hardware/quality lanes.
 
-- load full GGUF locally for immediate single-node performance
+Final release compares distributed GGUF with distributed safetensors using thresholds locked before seeing final results.
-- optionally load only selected tensors/layers
-- execute a layer range against inbound hidden states
-- expose outbound hidden states at a boundary
-- own per-session KV/state for only the loaded layer range
-- support prefill chunks and decode-step calls
-- expose model-specific cache metadata for DSA/MLA without requiring the tracker to understand tensor internals
 
-If llama.cpp cannot expose these as stable APIs today, the collaboration target is an upstream extension rather than a long-lived fork.
+Required measurements:
 
-## Failure Model
+- 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.
 
-Alpha behavior:
+The GGUF path ships only if it is faster at acceptable quality or enables a larger otherwise-unroutable model at useful measured speed.
 
-- Route node drops during prefill: fail request and retry from scratch.
+## Implementation sequence
-- Route node drops during decode: fail request unless a recent KV snapshot exists.
-- Tracker restart: active sessions may be lost; completed billing records persist.
-- Node restart: local hot KV is lost.
 
-Later behavior:
+1. Lock benchmark/performance contract.
+2. Define gRPC/protobuf and exact recipe identity.
+3. Pin llama.cpp and create the minimal patch stack.
+4. Implement dense-Llama range loading and boundary parity.
+5. Implement concurrent local KV.
+6. Build and integrate the standalone worker.
+7. Pass local two-process real-model acceptance.
+8. Pass real heterogeneous two-machine acceptance.
+9. Add continuous batching and failure hardening.
+10. Enforce the GGUF-versus-safetensors release gate.
+11. Add Qwen3/Qwen3-MoE as a separately certified adapter.
+12. Prepare narrow upstream collaboration patches/tests.
 
-- periodic KV snapshots for long sessions
+See [the Ralph backlog](prd.json) and [implementation strategy](implementation-strategy.md).
-- prefix cache reuse across requests
-- route repair when a semantically equivalent node has the same model/layer range and compatible cache snapshot
-
-## Security And Trust
-
-Activation/KV data can reveal user prompts. Public volunteer routes are not private. For sensitive workloads:
-
-- use private swarms
-- allow paid trusted nodes
-- encrypt transport
-- avoid storing hot KV on untrusted shared cache servers
-- sample outputs for fraud/audit as already planned in alpha hardening

+# Focused implementation strategy: performant concurrent distributed inference
+
+Status: Accepted planning direction
+Last updated: 2026-07-13
+
+## Product objective
+
+Enable clients to run top open models that do not fit on one consumer machine by combining independently owned model Shards into performant, concurrent Inference Routes.
+
+The project is not trying to reproduce every vLLM feature or support every inference engine. It is optimizing for:
+
+1. Models larger than one node's RAM/VRAM.
+2. Useful interactive decode speed on consumer CPU, AMD, NVIDIA, Vulkan, and mixed routes where certified.
+3. Multiple concurrent Route Sessions without cache corruption or global serialization.
+4. A lean runtime with one control plane and one primary GGUF engine.
+5. Measured improvement over the existing Transformers/safetensors implementation.
+
+## Current reality
+
+The existing project already owns the differentiating distributed control plane:
+
+- Tracker-selected contiguous Shards.
+- Stable Route Sessions.
+- Local per-Shard Hot KV State in the Transformers reference backend.
+- Binary Activation Seams.
+- Relay/direct routing, cancellation, telemetry, billing, and capability admission.
+- Persistent relay and direct transport optimizations.
+
+The missing production path is a native GGUF execution worker that can load and execute only an assigned layer range while retaining local Hot KV State for concurrent Route Sessions.
+
+Whole-model llama.cpp, vLLM, and existing Transformers serving remain baselines or optional route kinds. They are not substitutes for native distributed Shards.
+
+## Performance hypothesis—not an assumption
+
+GGUF itself is a format. Performance comes from llama.cpp/GGML's quantized kernels, memory layout, mmap, backend scheduling, and reduced working set.
+
+Quantized GGUF may be faster or may merely fit a larger model. Comparisons against safetensors must report both speed and quality because BF16 safetensors and Q4/Q8 GGUF are not numerically equivalent.
+
+Before expensive native work, establish controlled lanes:
+
+- Same model architecture and upstream revision.
+- Same machine, prompt set, context, output length, sampling policy, and concurrency.
+- Transformers/safetensors BF16 or the current production recipe.
+- llama.cpp GGUF F16/BF16 or Q8 correctness lane where available.
+- Q4_K_M or selected production quantization performance/fit lane.
+- TTFT, prefill tok/s, decode tok/s, p50/p95 latency, RSS, VRAM, artifact size, energy where available, and output-quality drift.
+
+The program proceeds only if llama.cpp/GGUF provides at least one meaningful advantage recorded in a machine-readable performance contract:
+
+- Better decode or aggregate throughput at acceptable quality; or
+- Materially lower memory that makes the target model routable while preserving useful throughput.
+
+## Parallelism we will use
+
+### Public Inference Route: layer/pipeline parallelism
+
+Each node independently executes one contiguous Shard. Activations cross seams; weights and Hot KV State remain local.
+
+This is the only public cross-machine model-parallel primitive in the first runtime.
+
+### Per-node continuous batching
+
+Autoregressive tokens remain sequential within one generation. Throughput comes from batching decode steps from multiple active Route Sessions inside each node using llama.cpp batches and sequence IDs or bounded context pools.
+
+This is essential. A worker that globally serializes sessions is not production-ready.
+
+### Multiple complete routes: data parallelism
+
+The Tracker may select multiple complete routes for independent requests. This increases network throughput and availability without requiring collectives between routes.
+
+### Trusted composite node: optional tensor/expert parallelism
+
+Tensor parallelism and expert parallelism require frequent collectives and tight compatibility. They may be used later inside one operator-controlled composite node or managed cluster exposed as one logical provider. They are not public WAN routing primitives.
+
+### Deferred mechanisms
+
+- Disaggregated prefill and KV transfer.
+- Speculative decoding.
+- Cross-route prefix snapshots.
+- Route repair with KV migration.
+- Public tensor/expert parallel collectives.
+
+They remain out of the critical path until the native layer route passes performance and concurrency gates.
+
+## Reuse decisions
+
+### llama.cpp/GGML: primary runtime substrate
+
+Reuse:
+
+- GGUF parsing and mmap.
+- Quantized kernels.
+- CPU, CUDA, HIP/ROCm, Vulkan, Metal, and other supported backends.
+- Tokenizer and model architecture implementations.
+- KV and sequence operations.
+- Backend scheduler and graph execution.
+
+Maintain a small exact-commit fork only for the missing local seam:
+
+- Range-aware tensor ownership/loading.
+- Architecture-defined boundary input/output.
+- Intermediate boundary output without tail normalization.
+- Layer-filtered KV and sequence mapping.
+
+Keep networking, Tracker logic, billing, and public protocol outside llama.cpp. Upstream generic hooks where possible.
+
+### vLLM: concepts and optional managed backend
+
+Use unmodified vLLM only as:
+
+- A whole-model node backend.
+- A managed TP/PP/EP cluster represented as one logical provider.
+- A performance/correctness baseline.
+
+Adapt concepts, not runtime code:
+
+- Named intermediate tensor bundles.
+- Continuous batching and request-owner maps.
+- Versioned KV-transfer compatibility fingerprints.
+- Explicit send/receive/abort/failure lifecycle.
+- Load telemetry and unbiased route selection.
+
+Do not fork vLLM for public Shards and do not transplant PagedAttention, Torch process groups, or GGUF-plugin kernels into the llama.cpp worker.
+
+### Nakshatra, prima.cpp, llama-gguf, LiGGUF, GPUStack
+
+Use as source and test donors only:
+
+- Nakshatra: partial-GGUF patches, daemon concepts, replay cases.
+- prima.cpp: selected tensor ownership and local-layer KV evidence.
+- llama-gguf: small protocol and integration-test patterns.
+- LiGGUF: Q8 activation transport and tensor-reduction reference.
+- historical GPUStack: resource preflight and role-oriented placement.
+
+Do not adopt or fork their repositories wholesale.
+
+## Battle-proven transport decision
+
+Use gRPC over HTTP/2 with Protocol Buffers for the native C++ Shard worker protocol.
+
+Why:
+
+- Mature Python and C++ implementations.
+- Bidirectional streaming.
+- HTTP/2 flow control and connection reuse.
+- Deadlines, cancellation, status codes, TLS, authentication interceptors, and generated schemas.
+- Avoids inventing a socket protocol.
+
+Scope boundary:
+
+- OpenAI-compatible client/Gateway APIs remain HTTP/SSE.
+- Tracker/control APIs remain existing project interfaces.
+- One long-lived bidirectional gRPC stream serves one Route Session Activation Seam.
+- Existing relay/WebSocket infrastructure may carry the same versioned protobuf frames as opaque binary when direct gRPC reachability is unavailable.
+- Large prefill tensors are chunked into bounded frames; decode bundles stay small.
+- No QUIC/WebRTC/custom transport in this milestone.
+
+The public boundary uses a versioned named-tensor bundle rather than one anonymous tensor because architecture boundaries can require more than `hidden_states`.
+
+Minimum identity:
+
+```text
+schema version
+request/work id
+Route Session id and route epoch
+Model Artifact and runtime recipe fingerprint
+Shard range and effective start
+phase: prefill/decode/release/cancel
+position/token range
+named tensors with shape/dtype/byte order
+compression and checksum
+idempotency step id
+cache expectation/result
+```
+
+## Concurrency model
+
+A native worker must not use one global serving sequence or one lock around all model execution.
+
+Required ownership:
+
+```text
+(Route Session id, route epoch)
+    -> local sequence/context
+    -> Shard-local Hot KV State
+    -> bounded lease and memory accounting
+```
+
+The node scheduler:
+
+- Admits sessions against model memory and KV budget.
+- Forms compatible decode batches from active sessions.
+- Preserves per-session position and route order.
+- Applies bounded queues and backpressure.
+- Cancels/releases independently.
+- Reports queue, batch, KV, prefill, decode, and seam telemetry.
+
+Initial deterministic gate: at least four concurrent sessions on a small certified model with no token/KV cross-talk. Final concurrency targets are hardware/recipe-specific and recorded by capability admission rather than hardcoded globally.
+
+## Stage gates
+
+### Gate A: performance hypothesis
+
+Controlled safetensors-versus-GGUF benchmark produces a signed/reproducible report and locks thresholds. Stop native work if there is no meaningful speed or fit benefit.
+
+### Gate B: local range parity
+
+Two local processes own disjoint GGUF ranges and match whole-model llama.cpp within the certified numerical tolerance for prefill and greedy decode.
+
+### Gate C: concurrent KV
+
+Multiple Route Sessions prefill/decode concurrently with isolated local KV, bounded memory, cancellation, and release.
+
+### Gate D: real distributed route
+
+Two physical machines execute one model that uses both Shards. Synthetic activation tests do not satisfy this gate.
+
+### Gate E: consumer-hardware performance
+
+On certified consumer hardware, the GGUF route beats the current distributed safetensors route under the locked performance contract or enables a larger otherwise-unroutable model at useful measured speed.
+
+### Gate F: architecture expansion
+
+Only after dense Llama-family gates pass, add an explicit Qwen3/Qwen3-MoE adapter and certify it independently.
+
+## Scope discipline
+
+The following do not block the first production candidate:
+
+- New cryptocurrency/economics work.
+- New artifact P2P protocol.
+- QUIC or WebRTC.
+- vLLM fork.
+- Whole-repository Nakshatra/prima adoption.
+- Every GGUF architecture.
+- Automatic route repair.
+- Prefix snapshot migration.
+- Speculative decoding.
+- A large-model marketing demo before small-model parity and concurrency pass.
+
+Every optimization must preserve output contract, session isolation, cancellation, resource cleanup, capability admission, and per-node attribution.

-Status: ready-for-agent
-
-## What to build
-
-Add the narrowest end-to-end Route Session lifecycle that can be used by distributed inference routes: create a session, bind it to a selected Inference Route, expose status, and close it cleanly. This slice does not need real model cache yet; it proves stable session identity across the control plane and activation plane.
-
-## Acceptance criteria
-
-- [ ] A request can create a Route Session with a stable `session_id`, `route_id`, model preset, backend id, and route membership.
-- [ ] Every downstream activation request carries the same session identity and fails clearly if the session or route id does not match.
-- [ ] Session status reports phase, route nodes, model preset, backend id, created time, and last activity time.
-- [ ] Closing a session releases all registered per-session state.
-- [ ] Tests cover create, status, close, stale-session rejection, and wrong-route rejection.

-## What to build
-
-Split the activation protocol into explicit prefill and decode-step calls using the existing binary HTTP direction from ADR-0008.

-# 03 — Generation Telemetry and streaming response contract
-
-Status: ready-for-agent
-
-## What to build
-
-Expose realtime Generation Telemetry for active Route Sessions and stream token deltas when the serving path can produce them. This slice should make long distributed requests observable before real large-model work begins.
-
-## Acceptance criteria
-
-- [ ] A client can observe route-session phase changes: queued, loading, prefill, decode, finalizing, completed, failed.
-- [ ] Telemetry includes prefill progress, generated token count, rolling tokens/sec, average tokens/sec, active route nodes, and failure reason.
-- [ ] Telemetry is available before the first output token.
-- [ ] A streaming response can include token deltas while telemetry remains available.
-- [ ] A non-streaming fallback still exposes telemetry until final answer or failure.
-- [ ] Route-node failure reports the last known phase and reason.
-- [ ] Tests cover telemetry updates, streaming token deltas, non-streaming fallback, and structured failure closeout.

-# 04 — PyTorch distributed KV reference route
-
-Status: ready-for-agent
-
-## What to build
-
-Fix the existing distributed PyTorch route so it uses the Route Session and prefill/decode protocol to keep Hot KV State local to each Shard node. The visible behavior is that prefill processes the prompt once, and decode no longer recomputes or resends the full growing prompt for every token.
-
-## Acceptance criteria
-
-- [ ] Distributed PyTorch prefill stores per-session cache/state on each Shard node.
-- [ ] Distributed PyTorch decode-step reads and appends local per-shard cache/state.
-- [ ] Decode activation seam payload is one token/hidden-state step after prefill.
-- [ ] The old full-growing-prompt decode loop is not used for models that support the reference cache path.
-- [ ] Unsupported model/cache APIs fail with an explicit backend capability error.
-- [ ] Session close or TTL cleanup releases per-shard cache.

-# 07 — llama.cpp layer-boundary prototype
-
-Status: ready-for-human
-
-## What to build
-
-Build a local prototype that proves whether llama.cpp/libllama can support the platform's distributed execution contract: execute a selected layer range, accept inbound hidden states, emit outbound hidden states, and own per-session cache for only the loaded/served range.
-
-This is the collaboration package for upstream llama.cpp. The target is an upstreamable API shape, not a permanent fork.
-
-## Acceptance criteria
-
-- [ ] A small llama.cpp-supported GGUF model can be split into a two-process localhost head/tail prototype.
-- [ ] The head process runs embeddings and early layers, then emits hidden states at an Activation Seam.
-- [ ] The tail process accepts hidden states, runs later layers plus output head, and produces logits/tokens comparable to single-process execution.
-- [ ] Prefill is performed once and decode-step seam payload is one hidden-state step per generated token.
-- [ ] Each process owns only its own per-session cache/state.
-- [ ] The prototype records the minimum upstream API needed for layer-range execution, hidden-state I/O, partial loading/introspection, and per-session KV ownership.
-- [ ] If upstream support is unavailable, the issue ends with a concrete recommendation: upstream proposal, narrow adapter fork, or keep GGUF distribution local-only for now.

+- [ ] 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.
+- [ ] Targeted pytest tests pass
+- [ ] python -m compileall packages tests passes for Python changes
+- [ ] git diff --check passes
+- [ ] Default tests remain deterministic, model-download-free, API-credit-free, and GPU-free
+- [ ] Full deterministic pytest -q passes, or the exact pre-existing unrelated failure is recorded with a clean-tree reproduction
+- [ ] Pinned native C++ target builds and focused CTest/protocol tests pass where native code is touched
+- [ ] llama.cpp patch stack applies cleanly to the exact pinned commit where patch code is touched
+- [ ] Read .scratch/distributed-gguf-runtime/RALPH-CONTEXT.md and this story issue completely before changing code
+- [ ] Read and verify every dependency evidence README before relying on dependency behavior
+- [ ] Preserve all pre-existing working-tree changes and stage only files belonging to this story
+- [ ] Write .scratch/distributed-gguf-runtime/evidence/DGR-009/README.md with files changed, exact commands and real results, limitations, compatibility notes, and dependent-story handoff
+- [ ] Update only this story issue to Status: done after every acceptance criterion and quality gate passes
+
+## Dependency handoff
+
+- `DGR-003` must have `passes: true`; read `../evidence/DGR-003/README.md` and verify its referenced files/commands.
+- `DGR-008` must have `passes: true`; read `../evidence/DGR-008/README.md` and verify its referenced files/commands.
+
+## Finish contract
+
+- Create the task evidence directory and durable handoff required above.
+- Preserve real failures and blockers; never fabricate benchmark, model, test or hardware output.
+- Change this issue to `Status: done` only after all criteria pass.
+- Emit `<promise>COMPLETE</promise>` only after the evidence handoff exists.

-# 10 — GLM-5.2 and Ornith follow-up support audit
-
-Status: pending
-
-## What to build
-
-Audit GLM-5.2 and Ornith after the smaller protocol smoke path and DeepSeek-V4-Flash audit. The output is a follow-up compatibility matrix focused on architecture/runtime blockers: DSA/MLA, hybrid attention, cache accounting, and GGUF/llama.cpp support.
-
-## Acceptance criteria
-
-- [ ] Verify GLM-5.2 PyTorch/Transformers serving requirements and cache semantics from primary model documentation.
-- [ ] Verify llama.cpp/GGUF support status for `glm_moe_dsa` or equivalent architecture support.
-- [ ] Verify Ornith/Qwen3.5-MoE and hybrid attention support status in the candidate runtimes.
-- [ ] Estimate artifact size and 128K cache memory by Shard range for each model.
-- [ ] Identify smallest quality-preserving quantization worth testing.
-- [ ] Convert each runtime blocker into a follow-up issue or upstream collaboration note.

+
+Status: ready-for-agent
+
+## Mandatory fresh-session context
+
+- Read [RALPH-CONTEXT.md](../RALPH-CONTEXT.md) completely before changing code.
+- This issue is `DGR-010` in [prd.json](../prd.json).
+- Read the evidence README for every dependency listed below.
+- Inspect current code and `git status`; historical text and previous agent claims are not evidence.
+
+## Description
+
+As a release engineer, I need real local distributed parity before involving network variability.
+
+## Expected durable outputs
+
+- Real local two-process commands and configuration
+- Raw parity, memory and performance results
+- evidence/DGR-010/README.md
+
+## 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.
+- [ ] Targeted pytest tests pass
+- [ ] python -m compileall packages tests passes for Python changes
+- [ ] git diff --check passes
+- [ ] Default tests remain deterministic, model-download-free, API-credit-free, and GPU-free
+- [ ] Full deterministic pytest -q passes, or the exact pre-existing unrelated failure is recorded with a clean-tree reproduction
+- [ ] Pinned native C++ target builds and focused CTest/protocol tests pass where native code is touched
+- [ ] llama.cpp patch stack applies cleanly to the exact pinned commit where patch code is touched

+
+Status: ready-for-agent
+
+## Mandatory fresh-session context
+
+- Read [RALPH-CONTEXT.md](../RALPH-CONTEXT.md) completely before changing code.
+- This issue is `DGR-011` in [prd.json](../prd.json).
+- Read the evidence README for every dependency listed below.
+- Inspect current code and `git status`; historical text and previous agent claims are not evidence.
+
+## Description
+
+As a consumer-hardware operator, I need two physical machines to execute one GGUF model so that the distributed claim is real.
+
+## Expected durable outputs
+
+- Two-machine hardware/network/runtime manifest
+- Raw real-route metrics and output evidence
+- evidence/DGR-011/README.md
+
+## 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.
+- [ ] Targeted pytest tests pass
+- [ ] python -m compileall packages tests passes for Python changes
+- [ ] git diff --check passes
+- [ ] Default tests remain deterministic, model-download-free, API-credit-free, and GPU-free
+- [ ] Full deterministic pytest -q passes, or the exact pre-existing unrelated failure is recorded with a clean-tree reproduction
