+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.

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.

+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
-- 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
+Ask: "What's the public interface, and which seams should we test?"
 
-**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
 
-```
-WRONG (horizontal):
-  RED:   test1, test2, test3, test4, test5
-  GREEN: impl1, impl2, impl3, impl4, impl5
+- **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.
+- **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.
+- **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.

+## Rules of the loop
 
-## Workflow
-
-### 1. Planning
-
-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
-```
+- **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.
+- **Refactoring is not part of the loop.** It belongs to the review stage (see the `code-review` skill), not the red → green implementation cycle.

+description: Turn the current conversation into a spec and publish it to the project issue tracker — no interview, just synthesis of what you've already discussed.
+disable-model-invocation: true
+---
+
+This skill takes the current conversation context and codebase understanding and produces a spec (you may know this document as a PRD). Do NOT interview the user — just synthesize what you already know.
+
+The issue tracker and triage label vocabulary should have been provided to you — run `/setup-matt-pocock-skills` if not.
+
+## Process
+
+1. Explore the repo to understand the current state of the codebase, if you haven't already. Use the project's domain glossary vocabulary throughout the spec, and respect any ADRs in the area you're touching.
+
+2. Sketch out the seams at which you're going to test the feature. Existing seams should be preferred to new ones. Use the highest seam possible. If new seams are needed, propose them at the highest point you can. The fewer seams across the codebase, the better - the ideal number is one.
+
+Check with the user that these seams match their expectations.
+
+3. Write the spec using the template below, then publish it to the project issue tracker. Apply the `ready-for-agent` triage label - no need for additional triage.
+
+<spec-template>
+
+## Problem Statement
+
+The problem that the user is facing, from the user's perspective.
+
+## Solution
+
+The solution to the problem, from the user's perspective.
+
+## User Stories
+
+A LONG, numbered list of user stories. Each user story should be in the format of:
+
+1. As an <actor>, I want a <feature>, so that <benefit>
+
+<user-story-example>
+1. As a mobile bank customer, I want to see balance on my accounts, so that I can make better informed decisions about my spending
+</user-story-example>
+
+This list of user stories should be extremely extensive and cover all aspects of the feature.
+
+## Implementation Decisions
+
+A list of implementation decisions that were made. This can include:
+
+- The modules that will be built/modified
+- The interfaces of those modules that will be modified
+- Technical clarifications from the developer
+- Architectural decisions
+- Schema changes
+- API contracts
+- Specific interactions
+
+Do NOT include specific file paths or code snippets. They may end up being outdated very quickly.
+
+Exception: if a prototype produced a snippet that encodes a decision more precisely than prose can (state machine, reducer, schema, type shape), inline it within the relevant decision and note briefly that it came from a prototype. Trim to the decision-rich parts — not a working demo, just the important bits.
+
+## Testing Decisions
+
+A list of testing decisions that were made. Include:
+
+- A description of what makes a good test (only test external behavior, not implementation details)
+- Which modules will be tested
+- Prior art for the tests (i.e. similar types of tests in the codebase)

+description: Break a plan, spec, or the current conversation into a set of tracer-bullet tickets, each declaring its blocking edges, published to the configured tracker — edges as text in one file per ticket locally, or native blocking links on a real tracker.
+disable-model-invocation: true
+---
+
+# 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
+
+- [ ] Acceptance criterion 1
+- [ ] Acceptance criterion 2

+</local-ticket-template>
+
+<issue-template>
+
+## Parent
+
+A reference to the parent issue on the tracker (if the source was an existing issue, otherwise omit this section).
+

+## 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.

+The destination varies per effort, and naming it is the first act of charting — it shapes every ticket.

+
+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.

+
+## 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.

TAI token: do NOT issue/list now — ADR-0002 already locks listing behind $50k volume + 25 nodes/15 wallets plus an unresolved securities-review gate; only a dormant mainnet mint (cheap, ~few $ SOL) for name/branding reservation is in scope, bundled with treasury-key work, not before it. Treasury custody: bare keypair file (current runbook 02) is not acceptable for real funds — plan is **free native SPL multisig** (`spl-token create-multisig`, no protocol fee unlike Squads' 0.5 SOL), 2-of-3 signers, at least one cold/offline, others one-per-hired-VPS-provider to avoid correlated compromise (not yet built — ops task, no issue filed). Stake/slash asymmetry (registry/slash is a local Python adapter per ADR-0007, not on-chain) accepted for now since hired hosts are our own infra and friends aren't node operators — revisit before opening to real third-party node operators. A mainnet-vs-devnet boot guardrail was proposed and explicitly declined by the owner given the safe-by-default money flow above.
 
-**Two new issues from this session, both `ready-for-agent`:**
-- **21 — Honest-noise calibration corpus** (`.scratch/alpha-hardening/issues/21-honest-noise-calibration-corpus.md`) rescoped from "prod gate" to a **hard alpha-release blocker**. Confirmed by code read: `verify_activation_proofs()` (`packages/validator/meshnet_validator/audit.py:94-127`) returns bool only, no raw divergence value; fleet-dispatch exists but wrong shape (`server.py:2998-3104`, pinned routes + latency, not full-fleet + TOPLOC divergence); storage wrong shape (`registry_events` has no divergence/hardware columns). Three-part build: (1) surface raw TOPLOC distance from audit.py, (2) extend dispatch to hit every registered node with fixed prompt/seed, (3) new SQLite table keyed by node+GPU+dtype. Small-fleet exception granted (N = actual hired-VPS fleet size). Hired VPS hosts stay stake-free until this closes.
-- **23 — Dynamic HF-benchmarked pricing** (`.scratch/alpha-hardening/issues/23-dynamic-hf-pricing.md`), high priority but not a release blocker. Pricing today is 100% static (`DEFAULT_PRICE_PER_1K_TOKENS = 0.02`, `billing.py:21`; `model_presets.json` has no per-model price). Target: 80% of cheapest comparable provider on `https://huggingface.co/inference/models` (per-provider-per-model marketplace, `?search=` query param works, no confirmed JSON API — plain scrape attempted first, escalate to headless browser only if the table isn't in raw HTML). Human-verified `hf_aliases` + `hf_verified_match_note` (params/quantization) per model, not auto-discovered matching. Reuses the `_settlement_loop` daemon-thread pattern for a daily refresh; falls back silently to the static default on any failure.
+**Two new issues from this session:**
+- **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** — `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]].

+
+## What graphify is for
+
+Drop any folder of code, docs, papers, images, or video into graphify and get a queryable knowledge graph. Persistent across sessions, honest audit trail (EXTRACTED/INFERRED/AMBIGUOUS), community detection surfaces cross-document connections you wouldn't think to ask about.
+
+## What You Must Do When Invoked
+
+If the user invoked `/graphify --help` or `/graphify -h` (with no other arguments), print the contents of the `## Usage` section above verbatim and stop. Do not run any commands, do not detect files, do not default the path to `.`. Just print the Usage block and return.
+
+**Fast path — existing graph:** Before doing anything else, check whether `graphify-out/graph.json` exists. The expected location is `graphify-out/graph.json` relative to the **current working directory** (i.e. the project root where you are running commands). If it exists AND the user's request is a natural-language question about the codebase (e.g. "How does X work?", "What calls Y?", "Trace the data flow through Z") and NOT an explicit rebuild command (`--update`, `--cluster-only`, or a bare path/URL that implies fresh extraction): **skip Steps 1–5 entirely and jump straight to `## For /graphify query`.** Run `graphify query "<question>"` immediately. Do not run detect. Do not check corpus size. Do not ask the user to narrow. The graph is already built — use it.
+
+If no path was given, use `.` (current directory). Do not ask the user for a path.
+
+If the path argument starts with `https://github.com/` or `http://github.com/`, treat it as a GitHub URL - run Step 0 before anything else, then continue with the resolved local path.
+
+Follow these steps in order. Do not skip steps.
+
+### Step 0 - GitHub repos and multi-path merge (only if a URL or several paths)
+
+Only when the path is one or more `https://github.com/...` URLs, or several local subfolders to merge. See `references/github-and-merge.md` for the clone, cross-repo merge, and monorepo flow, then continue with the resolved local path. A plain local path skips this step.
+
+### Step 1 - Ensure graphify is installed
+
+```bash
+# Detect the correct Python interpreter (handles uv tool, pipx, venv, system installs)
+PYTHON=""
+GRAPHIFY_BIN=$(which graphify 2>/dev/null)
+# 1. uv tool installs — most reliable on modern Mac/Linux
+if [ -z "$PYTHON" ] && command -v uv >/dev/null 2>&1; then
+    _UV_PY=$(uv tool run --from graphifyy python -c "import sys; print(sys.executable)" 2>/dev/null)
+    if [ -n "$_UV_PY" ]; then PYTHON="$_UV_PY"; fi
+fi
+# 2. Read shebang from graphify binary (pipx and direct pip installs)
+if [ -z "$PYTHON" ] && [ -n "$GRAPHIFY_BIN" ]; then
+    _SHEBANG=$(head -1 "$GRAPHIFY_BIN" | tr -d '#!')
+    case "$_SHEBANG" in
+        *[!a-zA-Z0-9/_.@-]*) ;;
+        *) "$_SHEBANG" -c "import graphify" 2>/dev/null && PYTHON="$_SHEBANG" ;;
+    esac
+fi
+# 3. Fall back to python3
+if [ -z "$PYTHON" ]; then PYTHON="python3"; fi
+if ! "$PYTHON" -c "import graphify" 2>/dev/null; then
+    if command -v uv >/dev/null 2>&1; then
+        uv tool install --upgrade graphifyy -q 2>&1 | tail -3
+        _UV_PY=$(uv tool run --from graphifyy python -c "import sys; print(sys.executable)" 2>/dev/null)
+        if [ -n "$_UV_PY" ]; then PYTHON="$_UV_PY"; fi
+    else
+        "$PYTHON" -m pip install graphifyy -q 2>/dev/null \
+          || "$PYTHON" -m pip install graphifyy -q --break-system-packages 2>&1 | tail -3
+    fi
+fi
+# Write interpreter path for all subsequent steps (persists across invocations)
+mkdir -p graphify-out
+"$PYTHON" -c "import sys; open('graphify-out/.graphify_python', 'w', encoding='utf-8').write(sys.executable)"
+# Save scan root so `graphify update` (no args) knows where to look next time
+echo "$(cd INPUT_PATH && pwd)" > graphify-out/.graphify_root
+```
+
+If the import succeeds, print nothing and move straight to Step 2.
+
+**In every subsequent bash block, replace `python3` with `$(cat graphify-out/.graphify_python)` to use the correct interpreter.**
+
+### Step 2 - Detect files
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from graphify.detect import detect
+from pathlib import Path
+result = detect(Path('INPUT_PATH'))
+print(json.dumps(result, ensure_ascii=False))
+" > graphify-out/.graphify_detect.json
+```
+
+Replace INPUT_PATH with the actual path the user provided. Do NOT cat or print the JSON - read it silently and present a clean summary instead:
+
+```
+Corpus: X files · ~Y words
+  code:     N files (.py .ts .go ...)
+  docs:     N files (.md .txt ...)
+  papers:   N files (.pdf ...)
+  images:   N files
+  video:    N files (.mp4 .mp3 ...)
+```
+
+Omit any category with 0 files from the summary.
+
+Then act on it:
+- If `total_files` is 0: stop with "No supported files found in [path]."
+- If `skipped_sensitive` is non-empty: report the count and list the skipped file names, so a wrongly-flagged source or doc is visible and can be renamed or moved (#2106).
+- If `total_words` > 2,000,000 OR `total_files` > 500: show the warning. Then compute the top 5 first-level subdirectories by file count:
+  - Read `scan_root` from the detect JSON (always an absolute path to the resolved INPUT_PATH).
+  - Concatenate all file lists across all types (`code`, `document`, `paper`, `image`, `video`).
+  - Filter out any path that starts with `scan_root + "/graphify-out/"` to exclude converted sidecars.
+  - For each file, strip the `scan_root` prefix and take the first path component. Files directly in `scan_root` with no subdirectory count as `(root)`.
+  - If all files are in `(root)` with no subdirectories, do not ask to narrow — no subfolders exist. Instead suggest `--no-cluster` to skip the expensive clustering step and proceed.
+  - Otherwise rank by count, show the top 5 with file counts, then ask which subfolder to run on. Wait for the user's answer before proceeding.
+- Otherwise: proceed directly to Step 2.5 if video files were detected, or Step 3 if not.
+
+### Step 2.5 - Video and audio (only if video files detected)
+
+Skip this step entirely if `detect` returned zero `video` files. When the corpus has video or audio, see `references/transcribe.md` to transcribe them to text first, then treat the transcripts as doc files in Step 3.
+
+### Step 3 - Extract entities and relationships
+
+**Before starting:** note whether `--mode deep` was given. You must pass `DEEP_MODE=true` to every subagent in Step B2 if it was. Track this from the original invocation - do not lose it.
+
+This step has two parts: **structural extraction** (deterministic, free) and **semantic extraction** (LLM, costs tokens).
+
+> **graphify needs no API key. Never ask the user for one, and never block on one.** Code is extracted structurally (AST) with no LLM and no key at all — a code-only corpus (the common `/graphify .` on a repo) skips semantic extraction entirely, so it needs nothing here: go straight to Part A and skip Part B. Semantic extraction (only for docs, papers, and images) uses Gemini **only if** `GEMINI_API_KEY`/`GOOGLE_API_KEY` is already set; otherwise the host agent itself is the LLM. graphify does **not** read `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, or any other provider key. If you catch yourself about to prompt for, wait on, or stop because of a missing API key, that is a misread of this skill — proceed without one.

+**Before semantic extraction:** check whether `GEMINI_API_KEY` or `GOOGLE_API_KEY` is set. If neither is set, print this one-liner to the user:
+> Tip: set `GEMINI_API_KEY` or `GOOGLE_API_KEY` to use Gemini for semantic extraction (`pip install 'graphifyy[gemini]'`).
+
+Print it once, then continue — do not wait for the user to supply a key. If `GEMINI_API_KEY` or `GOOGLE_API_KEY` IS set, use `graphify.llm.extract_corpus_parallel(files, backend="gemini")` for semantic extraction instead of dispatching subagents. The default Gemini model is `gemini-3-flash-preview`; set `GRAPHIFY_GEMINI_MODEL` or pass `--model` in headless CLI flows to override it.
+
+> **No other API keys are read.** When `GEMINI_API_KEY`/`GOOGLE_API_KEY` are unset, semantic extraction falls to the host agent itself — the running session is the LLM. On a host that dispatches subagents (e.g. Claude Code), dispatch them as written in Part B. On a host that runs the CLI directly in a terminal and cannot dispatch subagents, do not stall: a code-only corpus has no semantic work, so write the empty semantic file (Part B "Fast path") and continue to Part C; for a corpus with docs/papers/images, either set a Gemini key or extract those inline yourself, but in no case prompt for `ANTHROPIC_API_KEY` — that prompt is a misread of this skill.
+
+**Run Part A (AST) and Part B (semantic) in parallel. Dispatch all semantic subagents AND start AST extraction in the same message. Both can run simultaneously since they operate on different file types. Merge results in Part C as before.**
+
+Note: Parallelizing AST + semantic saves 5-15s on large corpora. AST is deterministic and fast; start it while subagents are processing docs/papers.
+
+#### Part A - Structural extraction for code files
+
+For any code files detected, run AST extraction in parallel with Part B subagents:
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import sys, json
+from graphify.extract import collect_files, extract
+from pathlib import Path
+import json
+
+code_files = []
+detect = json.loads(Path('graphify-out/.graphify_detect.json').read_text(encoding=\"utf-8\"))
+for f in detect.get('files', {}).get('code', []):
+    code_files.extend(collect_files(Path(f)) if Path(f).is_dir() else [Path(f)])
+
+if code_files:
+    result = extract(code_files, cache_root=Path('INPUT_PATH'))
+    Path('graphify-out/.graphify_ast.json').write_text(json.dumps(result, indent=2, ensure_ascii=False), encoding=\"utf-8\")
+    print(f'AST: {len(result[\"nodes\"])} nodes, {len(result[\"edges\"])} edges')
+else:
+    Path('graphify-out/.graphify_ast.json').write_text(json.dumps({'nodes':[],'edges':[],'input_tokens':0,'output_tokens':0}, ensure_ascii=False), encoding=\"utf-8\")
+    print('No code files - skipping AST extraction')
+"
+```
+
+#### Part B - Semantic extraction (parallel subagents)
+
+**Fast path:** If detection found zero docs, papers, and images (code-only corpus), skip Part B entirely and go straight to Part C. AST handles code - there is nothing for semantic subagents to do. **First write an empty semantic file** so Part C's merge has its input (it reads `.graphify_semantic.json` unconditionally; without this a code-only run hits `FileNotFoundError`):
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from pathlib import Path
+Path('graphify-out/.graphify_semantic.json').write_text(json.dumps({'nodes':[],'edges':[],'hyperedges':[],'input_tokens':0,'output_tokens':0}), encoding='utf-8')
+"
+```
+
+**MANDATORY: You MUST use the Agent tool here. Reading files yourself one-by-one is forbidden - it is 5-10x slower. If you do not use the Agent tool you are doing this wrong.**
+
+Before dispatching subagents, print a timing estimate:
+- Load `total_words` and file counts from `graphify-out/.graphify_detect.json`
+- Estimate agents needed: `ceil(uncached_non_code_files / 22)` (chunk size is 20-25)
+- Estimate time: ~45s per agent batch (they run in parallel, so total ≈ 45s × ceil(agents/parallel_limit))
+- Print: "Semantic extraction: ~N files → X agents, estimated ~Ys"
+
+**Step B0 - Check extraction cache first**
+
+Before dispatching any subagents, check which files already have cached extraction results:
+
+SPEC_PATH below is the **absolute** path of the `references/extraction-spec.md` that ships beside this SKILL.md — the same file Step B2 loads and hands to every subagent. It is the extraction prompt, so cache entries are attributed to it: when a graphify upgrade changes the prompt, entries produced by the old one are re-extracted instead of replayed, and unchanged prompts keep their entries (#1939). Substitute the real path in both Step B0 and Step B3 — pass the same one to each, and do not drop the argument.
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from graphify.cache import check_semantic_cache
+from pathlib import Path
+
+detect = json.loads(Path('graphify-out/.graphify_detect.json').read_text(encoding=\"utf-8\"))
+# Only content files go to semantic extraction. Code is already covered structurally
+# by the AST pass (Part A); flattening every category here makes subagents re-read
+# every source file (#1392). Video is transcribed to a document in Step 2.5 first.
+all_files = [f for cat in ('document', 'paper', 'image') for f in detect['files'].get(cat, [])]
+
+cached_nodes, cached_edges, cached_hyperedges, uncached = check_semantic_cache(all_files, root='INPUT_PATH', prompt_file='SPEC_PATH')
+
+# Always (re)write the cache file: write hits, else DELETE any leftover from a prior
+# run so Part C never merges a stale .graphify_cached.json (#1392).
+if cached_nodes or cached_edges or cached_hyperedges:
+    Path('graphify-out/.graphify_cached.json').write_text(json.dumps({'nodes': cached_nodes, 'edges': cached_edges, 'hyperedges': cached_hyperedges}, ensure_ascii=False), encoding=\"utf-8\")
+else:
+    Path('graphify-out/.graphify_cached.json').unlink(missing_ok=True)
+Path('graphify-out/.graphify_uncached.txt').write_text('\n'.join(uncached), encoding=\"utf-8\")
+print(f'Cache: {len(all_files)-len(uncached)} files hit, {len(uncached)} files need extraction')
+"
+```
+
+Only dispatch subagents for files listed in `graphify-out/.graphify_uncached.txt`. If all files are cached, skip to Part C directly.
+
+**Step B1 - Split into chunks**
+
+Load files from `graphify-out/.graphify_uncached.txt`. Split into chunks of 20-25 files each. Each image gets its own chunk (vision needs separate context). When splitting, group files from the same directory together so related artifacts land in the same chunk and cross-file relationships are more likely to be extracted.
+
+**Step B2 - Dispatch ALL subagents in a single message (OpenCode)**
+
+> **OpenCode platform:** Uses `@mention` dispatch instead of the Agent tool. All mentions in a single message run in parallel.
+
+Dispatch one `@mention` per chunk — ALL in the same response:
+
+```
+@agent Chunk CHUNK_NUM of TOTAL_CHUNKS: [extraction prompt with FILE_LIST, CHUNK_NUM, TOTAL_CHUNKS, DEEP_MODE substituted]
+
+@agent Chunk 2 of TOTAL_CHUNKS: [next chunk]
+```
+
+Wait for all agents to return. Parse each response as JSON. Accumulate nodes/edges/hyperedges across all results and write to `graphify-out/.graphify_semantic_new.json`. If the `@agent` path cannot write chunk files, fall back to the serial path that writes each `graphify-out/.graphify_chunk_NN.json` before merge.
+
+Subagent prompt template:
+
+See `references/extraction-spec.md` for the exact subagent prompt (JSON schema, node-ID rules, confidence rubric, hyperedge, and vision rules). Load it only here, only when at least one chunk holds a doc, paper, or image; a pure-code corpus has skipped Part B and never reads it. Pass each agent that prompt verbatim with FILE_LIST, CHUNK_NUM, TOTAL_CHUNKS, and DEEP_MODE substituted.
+
+**Step B3 - Collect, cache, and merge**
+
+Wait for all subagents. For each result:
+- Check that `graphify-out/.graphify_chunk_NN.json` exists on disk — this is the success signal
+- If the file exists and contains valid JSON with `nodes` and `edges`, include it and save to cache
+- If the file is missing, the subagent was likely dispatched as read-only (Explore type) — print a warning: "chunk N missing from disk — subagent may have been read-only. Re-run with general-purpose agent." Do not silently skip.
+- If a subagent failed or returned invalid JSON, print a warning and skip that chunk - do not abort
+
+If more than half the chunks failed or are missing, stop and tell the user to re-run and ensure `subagent_type="general-purpose"` is used.
+
+Merge all chunk files into `.graphify_semantic_new.json`. **After each Agent call completes, read the real token counts from the Agent tool result's `usage` field and write them back into the chunk JSON before merging** — the chunk JSON itself always has placeholder zeros. Then run:
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json, glob
+from pathlib import Path
+
+chunks = sorted(glob.glob('graphify-out/.graphify_chunk_*.json'))
+all_nodes, all_edges, all_hyperedges = [], [], []
+total_in, total_out = 0, 0
+for c in chunks:
+    d = json.loads(Path(c).read_text(encoding=\"utf-8\"))
+    all_nodes += d.get('nodes', [])
+    all_edges += d.get('edges', [])
+    all_hyperedges += d.get('hyperedges', [])
+    total_in += d.get('input_tokens', 0)
+    total_out += d.get('output_tokens', 0)
+Path('graphify-out/.graphify_semantic_new.json').write_text(json.dumps({
+    'nodes': all_nodes, 'edges': all_edges, 'hyperedges': all_hyperedges,
+    'input_tokens': total_in, 'output_tokens': total_out,
+}, indent=2, ensure_ascii=False), encoding=\"utf-8\")
+print(f'Merged {len(chunks)} chunks: {total_in:,} in / {total_out:,} out tokens')
+"
+```
+
+Save new results to cache. Pass the same SPEC_PATH as Step B0 — it stamps each entry with the prompt that produced it, and a write under a different prompt than the read lands where the next run won't look (#1939):
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from graphify.cache import save_semantic_cache
+from pathlib import Path
+
+new = json.loads(Path('graphify-out/.graphify_semantic_new.json').read_text(encoding=\"utf-8\")) if Path('graphify-out/.graphify_semantic_new.json').exists() else {'nodes':[],'edges':[],'hyperedges':[]}
+uncached = [line for line in Path('graphify-out/.graphify_uncached.txt').read_text(encoding=\"utf-8\").splitlines() if line]
+saved = save_semantic_cache(new.get('nodes', []), new.get('edges', []), new.get('hyperedges', []), root='INPUT_PATH', allowed_source_files=uncached, prompt_file='SPEC_PATH')
+print(f'Cached {saved} files')
+"
+```
+
+Merge cached + new results into `graphify-out/.graphify_semantic.json`:

+
+### Step 4 - Build graph, cluster, analyze, generate outputs
+
+**Before starting:** the code blocks below pass `directed=IS_DIRECTED` to `build_from_json()`. Replace `IS_DIRECTED` with `True` if `--directed` was given (builds a `DiGraph` preserving edge direction source→target), otherwise `False` (the default undirected `Graph`). Substitute it the same way you substitute `INPUT_PATH` — do not leave the literal `IS_DIRECTED` in the code.
+
+```bash
+mkdir -p graphify-out
+$(cat graphify-out/.graphify_python) -c "
+import sys, json
+from graphify.build import build_from_json
+from graphify.cluster import cluster, score_all

+# Placeholder questions - regenerated with real labels in Step 5
+questions = suggest_questions(G, communities, labels)
+
+# Export FIRST and honor the #479 shrink-guard: to_json returns False (writing
+# nothing) when the new graph is smaller than the existing graph.json. Only write
+# GRAPH_REPORT.md + the analysis sidecar when the graph was actually written, so
+# they never describe a graph that graph.json doesn't contain (#1392).
+wrote = to_json(G, communities, 'graphify-out/graph.json')
+if not wrote:
+    print('ERROR: refused to shrink graphify-out/graph.json (existing graph has more nodes; #479).')
+    print('If this shrink is intentional (you deleted files), re-run a full build with --force.')

+"
+```
+
+If this step prints `ERROR: Graph is empty`, stop and tell the user what happened - do not proceed to labeling or visualization.
+
+Replace INPUT_PATH with the actual path.
+
+### Step 4.5 - Graph health check (read-only integrity gate)
+
+A non-destructive diagnostic on the extraction, before labeling. It surfaces edge collapse, dangling/missing endpoints, and self-loops — the silent-corruption modes of incremental updates and AST/LLM id mismatches. Read-only; never aborts.
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from pathlib import Path
+from graphify.diagnostics import diagnose_extraction, format_diagnostic_report
+
+extraction = json.loads(Path('graphify-out/.graphify_extract.json').read_text(encoding=\"utf-8\"))
+summary = diagnose_extraction(extraction, directed=IS_DIRECTED, root='INPUT_PATH')
+print(format_diagnostic_report(summary))
+flags = [f'{summary[k]} {label}' for k, label in (
+    ('dangling_endpoint_edges', 'dangling-endpoint edges'),
+    ('missing_endpoint_edges', 'missing-endpoint edges'),
+    ('self_loop_edges', 'self-loop edges'),
+    ('directed_same_endpoint_collapsed_edges', 'collapsed (directed) edges'),
+    ('undirected_same_endpoint_collapsed_edges', 'collapsed (undirected) edges'),
+) if summary.get(k, 0)]
+print('GRAPH HEALTH WARNING: ' + '; '.join(flags) + ' - graph may be incomplete/corrupt.' if flags else 'Graph health: OK (no dangling/missing/collapsed edges).')
+"
+```
+
+Substitute `IS_DIRECTED` and `INPUT_PATH` as in Step 4. If a `GRAPH HEALTH WARNING` prints, surface it in the final summary (do not abort — the graph is still usable, but the integrity issue must be visible, per the Honesty Rules).
+
+### Step 5 - Label communities
+
+Read `graphify-out/.graphify_analysis.json`. For each community key, look at its node labels and write a 2-5 word plain-language name (e.g. "Attention Mechanism", "Training Pipeline", "Data Loading").
+
+Then regenerate the report and save the labels for the visualizer:
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import sys, json
+from graphify.build import build_from_json
+from graphify.cluster import score_all
+from graphify.analyze import god_nodes, surprising_connections, suggest_questions

+
+extraction = json.loads(Path('graphify-out/.graphify_extract.json').read_text(encoding=\"utf-8\"))
+detection  = json.loads(Path('graphify-out/.graphify_detect.json').read_text(encoding=\"utf-8\"))
+analysis   = json.loads(Path('graphify-out/.graphify_analysis.json').read_text(encoding=\"utf-8\"))
+
+# root= as in Step 4 / the --update runbook (#1361) — same base for node-key parity.
+G = build_from_json(extraction, root='INPUT_PATH', directed=IS_DIRECTED)
+communities = {int(k): v for k, v in analysis['communities'].items()}
+cohesion = {int(k): v for k, v in analysis['cohesion'].items()}
+tokens = {'input': extraction.get('input_tokens', 0), 'output': extraction.get('output_tokens', 0)}
+
+# LABELS - replace these with the names you chose above
+labels = LABELS_DICT
+
+# Regenerate questions with real community labels (labels affect question phrasing)
+questions = suggest_questions(G, communities, labels)
+
+report = generate(G, communities, cohesion, labels, analysis['gods'], analysis['surprises'], detection, tokens, 'INPUT_PATH', suggested_questions=questions)
+Path('graphify-out/GRAPH_REPORT.md').write_text(report, encoding=\"utf-8\")
+Path('graphify-out/.graphify_labels.json').write_text(json.dumps({str(k): v for k, v in labels.items()}, ensure_ascii=False), encoding=\"utf-8\")
+print('Report updated with community labels')
+"
+```
+
+Replace `LABELS_DICT` with the actual dict you constructed (e.g. `{0: "Attention Mechanism", 1: "Training Pipeline"}`).
+Replace INPUT_PATH with the actual path.
+
+### Step 6 - Generate Obsidian vault (opt-in) + HTML
+
+**Generate HTML always** (unless `--no-viz`). **Obsidian vault only if `--obsidian` was explicitly given** — skip it otherwise, it generates one file per node.
+
+If `--obsidian` was given:
+
+- If `--obsidian-dir <path>` was also given, pass it via `--dir`. Otherwise defaults to `graphify-out/obsidian`.
+
+```bash
+graphify export obsidian
+# or with custom dir: graphify export obsidian --dir ~/vaults/my-project
+```
+
+Generate the HTML graph (always, unless `--no-viz`):
+
+```bash
+graphify export html  # auto-aggregates to community view if graph > 5000 nodes
+# or: graphify export html --no-viz
+```
+
+### Steps 6b-8 - Wiki, Neo4j, FalkorDB, SVG, GraphML, MCP, benchmark (only on their flags)
+
+These run only when their flag is present (`--wiki`, `--neo4j`/`--neo4j-push`, `--falkordb`/`--falkordb-push`, `--svg`, `--graphml`, `--mcp`) or, for the token-reduction benchmark, when `total_words` exceeds 5,000. A default run with no export flags skips all of them. See `references/exports.md` for each one. Run any `--wiki` export before Step 9 cleanup so `.graphify_labels.json` is still available.
+
+---
+
+### Step 9 - Save manifest, update cost tracker, clean up, and report

+
+Replace PATH_TO_DIR with the actual absolute path of the directory that was processed.
+
+Then paste these sections from GRAPH_REPORT.md directly into the chat:
+- God Nodes
+- Surprising Connections
+- Suggested Questions
+
+Do NOT paste the full report - just those three sections. Keep it concise.
+
+Then immediately offer to explore. Pick the single most interesting suggested question from the report - the one that crosses the most community boundaries or has the most surprising bridge node - and ask:
+
+> "The most interesting question this graph can answer: **[question]**. Want me to trace it?"
+
+If the user says yes, run `/graphify query "[question]"` on the graph and walk them through the answer using the graph structure - which nodes connect, which community boundaries get crossed, what the path reveals. Keep going as long as they want to explore. Each answer should end with a natural follow-up ("this connects to X - want to go deeper?") so the session feels like navigation, not a one-shot report.
+
+The graph is the map. Your job after the pipeline is to be the guide.
+

+
+## Interpreter guard for subcommands
+
+Before running any subcommand below (`--update`, `--cluster-only`, `query`, `path`, `explain`, `add`), check that `.graphify_python` exists. If it's missing (e.g. user deleted `graphify-out/`), re-resolve the interpreter first:
+
+```bash
+if [ ! -f graphify-out/.graphify_python ]; then
+    GRAPHIFY_BIN=$(which graphify 2>/dev/null)
+    if [ -n "$GRAPHIFY_BIN" ]; then
+        PYTHON=$(head -1 "$GRAPHIFY_BIN" | tr -d '#!')
+        case "$PYTHON" in *[!a-zA-Z0-9/_.@-]*) PYTHON="python3" ;; esac
+    else
+        PYTHON="python3"
+    fi
+    mkdir -p graphify-out
+    "$PYTHON" -c "import sys; open('graphify-out/.graphify_python', 'w', encoding='utf-8').write(sys.executable)"
+fi
+```
+
+## For --update and --cluster-only
+
+Both are non-default subcommands. `--update` re-extracts only new or changed files; `--cluster-only` reruns clustering on the existing graph. See `references/update.md` for both flows.
+
+---
+
+## For /graphify query
+
+When `graphify-out/graph.json` already exists and the user asks a question about the corpus, answer from the graph rather than rebuilding it:
+
+```bash
+graphify query "<question>"
+```
+
+Before traversal, expand the question against the graph's own vocabulary so a wording mismatch does not collapse the answer to noise. If the `graphify query` CLI is unavailable, fall back to an inline NetworkX traversal of `graphify-out/graph.json`. Answer using only what the graph output contains, and quote `source_location` when citing a specific fact. For that vocab-expansion step, the BFS/DFS traversal modes, the `--budget` cap, the NetworkX fallback, `save-result` feedback, and the `/graphify path` and `/graphify explain` flows, see `references/query.md`.
+
+---
+
+## For /graphify add and --watch
+
+Neither is part of the default build. When the user runs `/graphify add <url>` to fetch a URL into the corpus, or passes `--watch` to auto-rebuild on file changes, see `references/add-watch.md`.
+
+---
+
+## For the commit hook and native CLAUDE.md integration
+
+When the user asks to install the post-commit auto-rebuild hook or wire graphify into a project's CLAUDE.md, see `references/hooks.md`.
+
+---
+
+## Honesty Rules
+
+- Never invent an edge. If unsure, use AMBIGUOUS.
+- Never skip the corpus check warning.
+- Always show token cost in the report.
+- Never hide cohesion scores behind symbols - show the raw number.
+- Never run HTML viz on a graph with more than 5,000 nodes without warning the user.

+# graphify reference: add a URL and watch a folder
+
+Load this when the user ran `/graphify add <url>` or passed `--watch`. Neither is part of the default build.
+
+## For /graphify add
+
+Fetch a URL and add it to the corpus, then update the graph.
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import sys
+from graphify.ingest import ingest
+from pathlib import Path
+
+try:

+    sys.exit(1)
+except RuntimeError as e:
+    print(f'error: {e}', file=sys.stderr)
+    sys.exit(1)
+"
+```
+
+Replace `URL` with the actual URL, `AUTHOR` with the user's name if provided, `CONTRIBUTOR` likewise. If the command exits with an error, tell the user what went wrong - do not silently continue. After a successful save, automatically run the `--update` pipeline on `./raw` to merge the new file into the existing graph.
+
+Supported URL types (auto-detected):
+- YouTube / any video URL → audio downloaded via yt-dlp, transcribed to `.txt` on next run (requires `pip install 'graphifyy[video]'`)
+- Twitter/X → fetched via oEmbed, saved as `.md` with tweet text and author
+- arXiv → abstract + metadata saved as `.md`
+- PDF → downloaded as `.pdf`
+- Images (.png/.jpg/.webp) → downloaded, Claude vision extracts on next run
+- Any webpage → converted to markdown via html2text
+
+---
+
+## For --watch
+
+Start a background watcher that monitors a folder and auto-updates the graph when files change.
+
+```bash
+$(cat graphify-out/.graphify_python) -m graphify.watch INPUT_PATH --debounce 3
+```
+
+Replace INPUT_PATH with the folder to watch. Behavior depends on what changed:
+
+- **Code files only (.py, .ts, .go, etc.):** re-runs AST extraction + rebuild + cluster immediately, no LLM needed. `graph.json` and `GRAPH_REPORT.md` are updated automatically.
+- **Docs, papers, or images:** writes a `graphify-out/needs_update` flag and prints a notification to run `/graphify --update` (LLM semantic re-extraction required).
+
+Debounce (default 3s): waits until file activity stops before triggering, so a wave of parallel agent writes doesn't trigger a rebuild per file.
+
+Press Ctrl+C to stop.
+
+For agentic workflows: run `--watch` in a background terminal. Code changes from agent waves are picked up automatically between waves. If agents are also writing docs or notes, you'll need a manual `/graphify --update` after those waves.

+# graphify reference: extra exports and benchmark
+
+Load this when the user passed one of the export flags (`--wiki`, `--neo4j`, `--neo4j-push`, `--falkordb`, `--falkordb-push`, `--svg`, `--graphml`, `--mcp`), or when the corpus is large enough for the token-reduction benchmark. Each step runs only for its own flag.
+
+### Step 6b - Wiki (only if --wiki flag)
+
+**Only run this step if `--wiki` was explicitly given in the original command.**
+
+Run this before Step 9 (cleanup) so `.graphify_labels.json` is still available.
+
+```bash
+graphify export wiki
+```
+
+### Step 7 - Neo4j export (only if --neo4j or --neo4j-push flag)
+
+**If `--neo4j`** - generate a Cypher file for manual import:
+
+```bash
+graphify export neo4j
+```
+
+**If `--neo4j-push <uri>`** - push directly to a running Neo4j instance. Ask the user for credentials if not provided:
+
+```bash
+graphify export neo4j --push bolt://localhost:7687 --user neo4j --password PASSWORD
+```
+
+Default URI is `bolt://localhost:7687`, default user is `neo4j`. Uses MERGE - safe to re-run without creating duplicates.
+
+### Step 7a - FalkorDB export (only if --falkordb or --falkordb-push flag)
+
+**If `--falkordb`** - generate a Cypher file. The statements are OpenCypher, but FalkorDB's `GRAPH.QUERY` runs one statement at a time (no bulk script import like Neo4j's `cypher-shell`), so prefer `--falkordb-push` to load a graph. Use this only when you want the portable `cypher.txt` artifact:
+
+```bash
+graphify export falkordb
+```
+
+**If `--falkordb-push <uri>`** - push directly to a running FalkorDB instance. Credentials are optional; ask the user only if the instance requires auth:
+
+```bash
+graphify export falkordb --push falkordb://localhost:6379
+```
+
+Default URI is `falkordb://localhost:6379` (the scheme is informational - `redis://` or a bare `host:port` work too), auth is optional, and the target graph defaults to `graphify`. Uses MERGE - safe to re-run without creating duplicates.
+
+### Step 7b - SVG export (only if --svg flag)
+
+```bash
+graphify export svg
+```
+
+### Step 7c - GraphML export (only if --graphml flag)
+
+```bash
+graphify export graphml
+```
+
+### Step 7d - MCP server (only if --mcp flag)
+
+```bash
+$(cat graphify-out/.graphify_python) -m graphify.serve graphify-out/graph.json
+```
+
+This starts a stdio MCP server that exposes tools: `query_graph`, `get_node`, `get_neighbors`, `get_community`, `god_nodes`, `graph_stats`, `shortest_path`. Add to Claude Desktop or any MCP-compatible agent orchestrator so other agents can query the graph live.
+
+To configure in Claude Desktop, add to `claude_desktop_config.json`. Claude Desktop can't run `$(...)`, and under `uv tool install` the system `python3` can't import graphify — so set `command` to the **absolute interpreter path** printed by `cat graphify-out/.graphify_python`:
+```json
+{
+  "mcpServers": {
+    "graphify": {
+      "command": "<absolute path from: cat graphify-out/.graphify_python>",
+      "args": ["-m", "graphify.serve", "/absolute/path/to/graphify-out/graph.json"]
+    }
+  }
+}
+```
+
+### Step 8 - Token reduction benchmark (only if total_words > 5000)
+
+If `total_words` from `graphify-out/.graphify_detect.json` is greater than 5,000, run:
+
+```bash
+graphify benchmark
+```
+
+Print the output directly in chat. If `total_words <= 5000`, skip silently - the graph value is structural clarity, not token compression, for small corpora.

+# graphify reference: extraction subagent prompt
+
+Load this in Step 3 Part B when the corpus has at least one doc, paper, or image chunk. A pure-code corpus skips Part B and never reads this file. Each semantic subagent receives the prompt below verbatim (substitute FILE_LIST, CHUNK_NUM, TOTAL_CHUNKS, DEEP_MODE, and CHUNK_PATH).
+
+```
+You are a graphify extraction subagent. Read the files listed and extract a knowledge graph fragment.
+Output ONLY valid JSON matching the schema below - no explanation, no markdown fences, no preamble.
+
+Files (chunk CHUNK_NUM of TOTAL_CHUNKS):
+FILE_LIST
+
+Rules:
+- EXTRACTED: relationship explicit in source (import, call, citation, "see §3.2")
+- INFERRED: reasonable inference (shared data structure, implied dependency)
+- AMBIGUOUS: uncertain - flag for review, do not omit
+
+Code files: focus on semantic edges AST cannot find (call relationships, shared data, arch patterns).
+  Do not re-extract imports - AST already has those.
+Doc/paper files: extract named concepts, entities, citations. For rationale (WHY decisions were made, trade-offs, design intent): store as a `rationale` attribute on the relevant concept node — do NOT create a separate rationale node or fragment node. Only create a node for something that is itself a named entity or concept. Use `file_type:"rationale"` for concept-like nodes (ideas, principles, mechanisms, design patterns). `file_type` MUST be one of exactly these six values: `code`, `document`, `paper`, `image`, `rationale`, `concept`. Any other value is invalid and will be rejected.
+Code files: when adding `calls` edges, source MUST be the caller (the function/class doing the calling), target MUST be the callee. Never reverse this direction. `calls` edges MUST stay within one language: a Python function cannot `calls` a JS/TS/Go/Rust/Java symbol and vice versa — cross-language call edges are phantom artifacts, never emit them.
+Image files: use vision to understand what the image IS - do not just OCR.
+  UI screenshot: layout patterns, design decisions, key elements, purpose.
+  Chart: metric, trend/insight, data source.
+  Tweet/post: claim as node, author, concepts mentioned.
+  Diagram: components and connections.
+  Research figure: what it demonstrates, method, result.
+  Handwritten/whiteboard: ideas and arrows, mark uncertain readings AMBIGUOUS.
+
+DEEP_MODE (if --mode deep was given): be aggressive with INFERRED edges - indirect deps,
+  shared assumptions, latent couplings. Mark uncertain ones AMBIGUOUS instead of omitting.
+
+Semantic similarity: if two concepts in this chunk solve the same problem or represent the same idea without any structural link (no import, no call, no citation), add a `semantically_similar_to` edge marked INFERRED with a confidence_score reflecting how similar they are (0.6-0.95). Examples:
+- Two functions that both validate user input but never call each other
+- A class in code and a concept in a paper that describe the same algorithm
+- Two error types that handle the same failure mode differently
+Only add these when the similarity is genuinely non-obvious and cross-cutting. Do not add them for trivially similar things.
+
+Hyperedges: if 3 or more nodes clearly participate together in a shared concept, flow, or pattern that is not captured by pairwise edges alone, add a hyperedge to a top-level `hyperedges` array. Examples:
+- All classes that implement a common protocol or interface
+- All functions in an authentication flow (even if they don't all call each other)
+- All concepts from a paper section that form one coherent idea
+Use sparingly — only when the group relationship adds information beyond the pairwise edges. Maximum 3 hyperedges per chunk.
+
+If a file has YAML frontmatter (--- ... ---), copy source_url, captured_at, author,
+  contributor onto every node from that file.
+
+confidence_score is REQUIRED on every edge - never omit it, never use 0.5 as a default:
+- EXTRACTED edges: confidence_score = 1.0 always
+- INFERRED edges: pick exactly ONE value from this set — never 0.5:
+    0.95  direct structural evidence (shared data structure, named cross-file reference).
+    0.85  strong inference (clear functional alignment, no direct symbol link).
+    0.75  reasonable inference (shared problem domain + similar shape, requires interpretation).
+    0.65  weak inference (thematically related, no shape evidence).
+    0.55  speculative but plausible (surface-level co-occurrence only).
+  Models follow discrete rubrics better than continuous ranges; the bimodal
+  distribution observed in production (>50% at 0.5, >40% at 0.85+) shows the
+  range guidance is being collapsed to a binary. If no value above fits, mark
+  the edge AMBIGUOUS rather than picking 0.4 or below.
+- AMBIGUOUS edges: 0.1-0.3
+
+Node ID format: lowercase, only `[a-z0-9_]`, no dots or slashes. Format: `{stem}_{entity}` where stem is the **full repo-relative path with the extension dropped**, every path segment kept and joined with `_` (each segment lowercased with non-alphanumeric chars replaced by `_`), and entity is the symbol name similarly normalized. Use every directory level, not just the immediate parent — this keeps same-named files in different directories distinct. Examples: `src/auth/session.py` + `ValidateToken` → `src_auth_session_validatetoken`; `lib/utils/helpers.py` + `parse_url` → `lib_utils_helpers_parse_url`; `tests/test_foo.py` + `_helper` → `tests_test_foo_helper`; `docs/v1/api/README.md` + `getUser` → `docs_v1_api_readme_getuser`. Top-level files (no parent dir, e.g. `setup.py`) use just the filename stem: `setup_my_func`. This must match the ID the AST extractor generates — using just the filename (e.g., `session_validatetoken`) or only the immediate parent (e.g., `auth_session_validatetoken`) will create orphan ghost-duplicate nodes. If you are re-extracting a project built under the old immediate-parent format, the user should run `graphify extract --force` to rebuild cleanly. CRITICAL: never append chunk numbers, sequence numbers, or any suffix to an ID (no `_c1`, `_c2`, `_chunk2`, etc.). IDs must be deterministic from the label alone — the same entity must always produce the same ID regardless of which chunk processes it.
+
+Generate the extraction JSON matching this schema exactly:
+{"nodes":[{"id":"auth_session_validatetoken","label":"Human Readable Name","file_type":"code|document|paper|image|rationale|concept","source_file":"<FILE_LIST path verbatim>","source_location":null,"source_url":null,"captured_at":null,"author":null,"contributor":null}],"edges":[{"source":"node_id","target":"node_id","relation":"calls|implements|references|cites|conceptually_related_to|shares_data_with|semantically_similar_to|rationale_for","confidence":"EXTRACTED|INFERRED|AMBIGUOUS","confidence_score":1.0,"source_file":"<FILE_LIST path verbatim>","source_location":null,"weight":1.0}],"hyperedges":[{"id":"snake_case_id","label":"Human Readable Label","nodes":["node_id1","node_id2","node_id3"],"relation":"participate_in|implement|form","confidence":"EXTRACTED|INFERRED","confidence_score":0.75,"source_file":"<FILE_LIST path verbatim>"}],"input_tokens":0,"output_tokens":0}
+
+source_file RULE (every node, edge, and hyperedge): set source_file to the path of the originating file EXACTLY as it appears in FILE_LIST — verbatim and absolute. Do NOT shorten to a basename, do NOT re-relativize, do NOT strip any directory prefix, and do NOT change separators (the engine canonicalizes separators and relativizes against the build root downstream). Copy the FILE_LIST entry character-for-character. This keeps the full build and incremental --update on the same base, so build_merge's replace-on-re-extract matches the existing node instead of accumulating a duplicate.
+
+Then write the JSON to disk using the Write tool at this exact absolute path (no relative paths — Write resolves relative paths against an undefined cwd and the file will be silently lost):
+CHUNK_PATH

+# graphify reference: GitHub clone and cross-repo merge
+
+Load this when the user passed one or more `https://github.com/...` URLs, or named several local subfolders to merge into one graph.
+
+### Step 0 - Clone GitHub repo(s) (only if a GitHub URL was given)
+
+**Single repo:**
+```bash
+LOCAL_PATH=$(graphify clone <github-url> [--branch <branch>])
+# Use LOCAL_PATH as the target for all subsequent steps
+```
+
+**Multiple repos (cross-repo graph):**
+```bash
+# Clone each repo, run the full pipeline on each, then merge
+graphify clone <url1>   # → ~/.graphify/repos/<owner1>/<repo1>
+graphify clone <url2>   # → ~/.graphify/repos/<owner2>/<repo2>
+# Run /graphify on each local path to produce their graph.json files
+# Then merge:
+graphify merge-graphs \
+  ~/.graphify/repos/<owner1>/<repo1>/graphify-out/graph.json \
+  ~/.graphify/repos/<owner2>/<repo2>/graphify-out/graph.json \
+  --out graphify-out/cross-repo-graph.json
+```
+
+Graphify clones into `~/.graphify/repos/<owner>/<repo>` and reuses existing clones on repeat runs. Each node in the merged graph carries a `repo` attribute so you can filter by origin.
+
+**Multiple local subfolders (monorepo or multi-service layout):**
+
+The skill pipeline writes all intermediate and final outputs to `graphify-out/` in the current working directory. Running the skill on each subfolder separately will clobber the same output dir. Instead, use the CLI directly for each subfolder — it places `graphify-out/` *inside* the scanned path:
+
+```bash
+graphify extract ./core/     # → ./core/graphify-out/graph.json
+graphify extract ./service/  # → ./service/graphify-out/graph.json
+graphify extract ./platform/ # → ./platform/graphify-out/graph.json
+# Add --backend gemini|kimi|openai|deepseek|claude-cli depending on which API key you have set
+
+# Then merge at the project root:
+graphify merge-graphs \
+  ./core/graphify-out/graph.json \
+  ./service/graphify-out/graph.json \
+  ./platform/graphify-out/graph.json \
+  --out graphify-out/graph.json
+```
+
+Once `graphify-out/graph.json` exists, the fast path above takes over: any codebase question runs `graphify query` directly on the merged graph — no re-extraction, no size gate.

+# graphify reference: query, path, explain
+
+Load this when the user asks a question against an existing graph, or runs `/graphify path` or `/graphify explain`. The core's query stub points here for the full traversal flow. These flows use the `graphify query` CLI when it is available and fall back to an inline NetworkX traversal otherwise.
+
+Two traversal modes - choose based on the question:
+
+| Mode | Flag | Best for |
+|------|------|----------|
+| BFS (default) | _(none)_ | "What is X connected to?" - broad context, nearest neighbors first |
+| DFS | `--dfs` | "How does X reach Y?" - trace a specific chain or dependency path |
+
+First check the graph exists:
+```bash
+$(cat graphify-out/.graphify_python) -c "
+from pathlib import Path
+if not Path('graphify-out/graph.json').exists():
+    print('ERROR: No graph found. Run /graphify <path> first to build the graph.')
+    raise SystemExit(1)
+"
+```
+If it fails, stop and tell the user to run `/graphify <path>` first.
+
+### Step 0 — Constrained query expansion (REQUIRED before traversal)
+
+graphify's `query` CLI matches nodes via case-folded substring + IDF — there is **no stemming, no synonyms, no cross-language match** inside the binary, and the inline fallback below matches the same way. If the user's question uses different language or different domain vocabulary than the graph's labels (user says "обработчик" / graph says "handler"; user says "authentication" / graph says "Guardian"), the literal matcher returns 0 hits and the answer collapses to noise.
+
+Fix this **without inventing tokens** by expanding the query against the actual graph vocabulary first:
+
+1. Extract the token vocabulary from node labels:
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json, re
+from pathlib import Path
+data = json.loads(Path('graphify-out/graph.json').read_text(encoding='utf-8'))
+vocab = set()
+for n in data['nodes']:
+    for c in re.findall(r'[^\W\d_]+', n.get('label','') or '', re.UNICODE):
+        parts = re.findall(r'[A-Z]+(?=[A-Z][a-z])|[A-Z]?[a-z]+|[A-Z]+', c) or [c]
+        for p in parts:
+            t = p.lower()
+            if 3 <= len(t) <= 30:
+                vocab.add(t)
+Path('graphify-out/.vocab.txt').write_text('\n'.join(sorted(vocab)), encoding='utf-8')
+print(f'vocab: {len(vocab)} tokens')
+"
+```
+
+2. Read `graphify-out/.vocab.txt`. Then for the user's question, select **up to 12 tokens from this exact list** that semantically match the query intent. Hard constraints:
+   - You MUST pick only tokens present in the vocabulary file. Do NOT invent tokens.
+   - If a query concept has no plausible token in the vocab, skip it — do not substitute a near-synonym from training memory.
+   - If **no** vocab tokens match the query at all, output an empty list and tell the user the corpus has no relevant vocabulary for this question. Do not fabricate a search.
+   - Translate cross-language: Russian "аутентификация" → look for `auth`, `credential`, `token`, `security` IFF present in vocab.
+   - Morphology: "handlers" maps to `handler` IFF present; "todos" maps to `todo` IFF present.
+
+3. Print the selection explicitly to the user before running the query, so the expansion is auditable:
+```
+Query expanded to (from graph vocab, N tokens): [token1, token2, ...]
+```
+If the list is empty, say so plainly and stop — do not proceed to traversal.
+
+### Step 1 — Traversal

+Build the **expanded query string** by joining the selected tokens with spaces. Use this string as `QUESTION` below — NOT the original user question. (The original question is preserved only for `save-result` at the end.)
+
+Prefer the CLI when it is installed:
+```bash
+graphify query "QUESTION"
+# or: graphify query "QUESTION" --dfs --budget 3000
+```
+
+If the CLI is unavailable, load `graphify-out/graph.json` and run the traversal inline:
+
+1. Find the 1-3 nodes whose label best matches the expanded tokens.
+2. Run the appropriate traversal from each starting node.
+3. Read the subgraph - node labels, edge relations, confidence tags, source locations.
+4. Answer using **only** what the graph contains. Quote `source_location` when citing a specific fact.
+5. If the graph lacks enough information, say so - do not hallucinate edges.
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import sys, json
+from networkx.readwrite import json_graph

+"
+```
+
+Replace `QUESTION` with the **expanded** query string, `MODE` with `bfs` or `dfs`, and `BUDGET` with the token budget (default `2000`, or whatever `--budget N` specifies). Then answer based on the subgraph output above, using only what the graph contains.
+
+After writing the answer, save it back into the graph so it improves future queries. Include the expanded tokens inside the `--answer` text (e.g. `"Expanded from original query via vocab: [tokens]. Then traversed..."`) so the next `--update` extracts the expansion history as a graph node:
+
+```bash
+$(cat graphify-out/.graphify_python) -m graphify save-result --question "ORIGINAL_QUESTION" --answer "ANSWER" --type query --nodes NODE1 NODE2
+```
+
+Replace `ORIGINAL_QUESTION` with the user's verbatim question, `ANSWER` with your full answer text (containing the expanded-token trace), `NODE1 NODE2` with the list of node labels you cited. This closes the feedback loop: the next `--update` will extract this Q&A as a node in the graph.
+
+**Work memory (self-improving loop).** Add an `--outcome` so future sessions learn from this one — append `--outcome useful|dead_end|corrected` to the `save-result` command (and `--correction "the right answer"` when correcting):
+
+- `useful` — the cited nodes answered the question well (they become *preferred sources*).
+- `dead_end` — the question/path led nowhere; don't re-derive it next time.
+- `corrected` — the saved answer was wrong; `--correction` records what was right.
+
+At the **start** of graph work, refresh and read the lessons: run `graphify reflect --if-stale` (cheap, deterministic, no LLM; `--if-stale` makes it a no-op when `LESSONS.md` is already newer than every input, e.g. when the git hook just refreshed it), then read `graphify-out/reflections/LESSONS.md`. It lists **preferred sources** (start there), **known dead ends** (skip them), and prior **corrections**. Running `reflect` yourself keeps the lessons current even without the git hook installed; if the post-commit hook *is* installed, `--if-stale` means your session-start run costs almost nothing.

+# graphify reference: transcribe video and audio
+
+Load this only when `detect` reported one or more `video` files. A corpus with no video never reads this.
+
+### Step 2.5 - Transcribe video / audio files (only if video files detected)
+
+Skip this step entirely if `detect` returned zero `video` files.
+
+Video and audio files cannot be read directly. Transcribe them to text first, then treat the transcripts as doc files in Step 3.
+
+**Strategy:** Read the god nodes from `graphify-out/.graphify_detect.json` (or the analysis file if it exists from a previous run). You are already a language model — write a one-sentence domain hint yourself from those labels. Then pass it to Whisper as the initial prompt. No separate API call needed.
+
+**However**, if the corpus has *only* video files and no other docs/code, use the generic fallback prompt: `"Use proper punctuation and paragraph breaks."`
+
+**Step 1 - Write the Whisper prompt yourself.**
+
+Read the top god node labels from detect output or analysis, then compose a short domain hint sentence, for example:
+
+- Labels: `transformer, attention, encoder, decoder` → `"Machine learning research on transformer architectures and attention mechanisms. Use proper punctuation and paragraph breaks."`
+- Labels: `kubernetes, deployment, pod, helm` → `"DevOps discussion about Kubernetes deployments and Helm charts. Use proper punctuation and paragraph breaks."`
+
+**Export** it as `GRAPHIFY_WHISPER_PROMPT` (the exact name the transcriber reads — and it must be `export`ed so the child Python process sees it) for the next command.
+
+**Step 2 - Transcribe:**
+
+```bash
+export GRAPHIFY_WHISPER_MODEL=base  # or whatever --whisper-model the user passed (must be exported)
+export GRAPHIFY_WHISPER_PROMPT="<the one-sentence domain hint you composed in Step 1>"
+$(cat graphify-out/.graphify_python) -c "
+import json, os, sys
+from pathlib import Path
+from graphify.transcribe import transcribe_all
+
+detect = json.loads(Path('graphify-out/.graphify_detect.json').read_text(encoding=\"utf-8\"))
+video_files = detect.get('files', {}).get('video', [])
+prompt = os.environ.get('GRAPHIFY_WHISPER_PROMPT', 'Use proper punctuation and paragraph breaks.')
+
+transcript_paths = transcribe_all(video_files, initial_prompt=prompt)
+# Write the JSON from Python (NOT a shell '>' redirect): transcribe_all/Whisper
+# print progress to stdout, which would otherwise corrupt the JSON file (#1392).
+Path('graphify-out/.graphify_transcripts.json').write_text(json.dumps(transcript_paths, ensure_ascii=False), encoding=\"utf-8\")
+print(f'Transcribed {len(transcript_paths)} file(s)', file=sys.stderr)
+"
+```
+
+After transcription:
+- Read the transcript paths from `graphify-out/.graphify_transcripts.json`
+- Add them to the docs list before dispatching semantic subagents in Step 3B
+- Print how many transcripts were created: `Transcribed N video file(s) -> treating as docs`
+- If transcription fails for a file, print a warning and continue with the rest
+
+**Whisper model:** Default is `base`. If the user passed `--whisper-model <name>`, `export GRAPHIFY_WHISPER_MODEL=<name>` (it must be exported, not just assigned) before running the command above.

+# graphify reference: incremental update and cluster-only
+
+Load this only when the user passed `--update` or `--cluster-only`. A first-time full build never reads this file.
+
+## For --update (incremental re-extraction)
+
+Use when you've added or modified files since the last run. Only re-extracts changed files - saves tokens and time.
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import sys, json
+from graphify.detect import detect_incremental, save_manifest
+from pathlib import Path
+
+result = detect_incremental(Path('INPUT_PATH'))
+new_total = result.get('new_total', 0)
+print(json.dumps(result, indent=2, ensure_ascii=False))
+Path('graphify-out/.graphify_incremental.json').write_text(json.dumps(result, ensure_ascii=False), encoding=\"utf-8\")
+deleted = list(result.get('deleted_files', []))
+if new_total == 0 and not deleted:
+    print('No files changed since last run. Nothing to update.')
+    raise SystemExit(0)
+if deleted:
+    print(f'{len(deleted)} deleted file(s) to prune.')
+if new_total > 0:
+    print(f'{new_total} new/changed file(s) to re-extract.')
+"
+```
+
+Then populate `.graphify_detect.json` so Steps 3A–6 (which read it unconditionally) see the right state for an incremental run. `files` carries the changed subset (drives Step 3A AST + Step 3B0 cache check on only what changed); `all_files` carries the full corpus for any step that needs corpus-wide context:
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from pathlib import Path
+r = json.loads(Path('graphify-out/.graphify_incremental.json').read_text(encoding=\"utf-8\"))
+Path('graphify-out/.graphify_detect.json').write_text(json.dumps({
+    'files': r.get('new_files', {}),
+    'all_files': r.get('files', {}),

+    'total_words': r.get('total_words', 0),
+    'skipped_sensitive': r.get('skipped_sensitive', []),
+    'needs_graph': True,
+}, ensure_ascii=False), encoding=\"utf-8\")
+"
+```
+
+If new files exist, first check whether all changed files are code files:
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from pathlib import Path
+
+result = json.loads(open('graphify-out/.graphify_incremental.json', encoding='utf-8').read()) if Path('graphify-out/.graphify_incremental.json').exists() else {}
+code_exts = {'.py','.ts','.js','.go','.rs','.java','.cpp','.c','.rb','.swift','.kt','.cs','.scala','.php','.cc','.cxx','.hpp','.h','.kts','.lua','.toc','.f','.F','.f90','.F90','.f95','.F95','.f03','.F03','.f08','.F08'}
+new_files = result.get('new_files', {})
+all_changed = [f for files in new_files.values() for f in files]
+code_only = all(Path(f).suffix.lower() in code_exts for f in all_changed)
+print('code_only:', code_only)
+"
+```
+
+If `code_only` is True: print `[graphify update] Code-only changes detected - skipping semantic extraction (no LLM needed)`, run only Step 3A (AST) on the changed files, skip Step 3B entirely (no subagents), then go straight to merge and Steps 4–8.
+
+If `code_only` is False (any changed file is a doc/paper/image/video): **first, if any changed file is in `new_files['video']`, run `references/transcribe.md` (Step 2.5) on those files, then rewrite `.graphify_detect.json` to move the resulting transcript paths into `files['document']` and drop `files['video']`** — otherwise raw `.mp4/.mp3` paths are fed to semantic subagents as unreadable media (#1392). Then run the full Steps 3A–3C pipeline as normal.
+
+
+If no new files exist (only deletions), create an empty extraction so the merge step can prune:
+
+```bash
+if [ ! -f graphify-out/.graphify_extract.json ]; then
+    echo '[graphify update] Only deletions -- creating empty extraction for merge.'
+    $(cat graphify-out/.graphify_python) -c "

+Before the merge step, save the old graph: `cp graphify-out/graph.json graphify-out/.graphify_old.json`
+Clean up after: `rm -f graphify-out/.graphify_old.json`

+
+## For --cluster-only
+
+Skip Steps 1–3. Re-run clustering on the existing graph:
+
+```bash
+graphify cluster-only .
+```
+
+`graphify cluster-only .` is **self-contained**: it re-clusters, names communities, and regenerates `GRAPH_REPORT.md`, `graph.json`, and `graph.html` from the existing graph. **Do not re-run Steps 5–9** — they read intermediate files (`.graphify_extract.json`, `.graphify_detect.json`, `.graphify_analysis.json`) that a prior build's cleanup (Step 9) already deleted, so they raise `FileNotFoundError` (#1392). When it finishes, present the refreshed `GRAPH_REPORT.md` summary as usual.

+[08:48:30] [INFO] [agent] **Summary:** Locked the alpha/beta performance contract for the DeepSeek V4 Flash distributed GGUF track as versioned, digest-sealed machine-readable data, before any distributed benchmark result exists.
+[08:48:30] [INFO] [agent] - New package `packages/node/meshnet_node/dgr_performance/` defines all four required lanes (controlled-safetensors, whole-model-gguf, dense-distributed-gguf, v4-flash-distributed) — the first two reference the pre-existing immutable DGR-001 lock rather than duplicating it; the other two are newly locked with fixed prompts, context/output lengths, sampling, concurrency, hardware, and metrics.
+[08:48:30] [INFO] [agent] - Alpha requires correctness plus a `human_approval`-gated useful-speed threshold (not an automatic ratio check); beta adds concurrency/long-context/failure/sustained-throughput. Quantization and 2-4/10+ stage counts are named certification-scenario labels only, enforced by a structural test that greps for hardcoding.
+[08:48:30] [INFO] [agent] - 28 new tests in `tests/test_dgr_performance_contract.py`, all passing; `compileall`, `git diff --check`, and `scripts/ralph_prd_schema.py validate` all clean.
+[08:48:30] [INFO] [agent] - Also found and fixed a pre-existing, unrelated problem: `prd.json`'s top-level schema/gates/milestones content had been silently dropped by some prior tooling pass (not caused by this story), which was breaking 56 tests — restored it from `HEAD` before building on top, same fix pattern DGR-018 used.
+[08:48:30] [INFO] [agent] - Evidence written to `.scratch/distributed-gguf-runtime/evidence/DGR-019/README.md`; `prd.json` marked `passes: true` with `completionNotes`; issue markdown regenerated. All changes left uncommitted for review.

+[09:09:19] [INFO] [agent] DGR-024 is complete. Summary:
+[09:09:19] [INFO] [agent] The real generated-gRPC protocol harness was already implemented and merged, but marked `passes: false` pending independent review. I performed that review: built a fresh `uv`-managed venv (neither the ambient interpreter nor the existing `.venv-rocm` has `grpc` installed) and reran all 11 harness tests for real — they pass, confirming the direct/opaque-relay byte-identity proof, fail-closed negative paths, and generated-stub-drift check all work as claimed.
+[09:09:19] [INFO] [agent] I found one real gap against acceptance criterion 5 ("...wire-frame hashes..."): the prior evidence proved wire fidelity only via byte-equality, with no hash ever recorded. I closed it by adding `requests_sha256`/`responses_sha256` to the server's `WireCapture.to_dict()` and extending the test to assert those server-persisted hashes match independently-computed client-side hashes and are identical between the direct and relay paths. I also recorded SHA-256 identities of the generated protobuf stubs.
+[09:09:19] [INFO] [agent] I also fixed a recurrence of the known `prd.json` top-level-field-drop bug (restoring it without touching the already-uncommitted DGR-019/DGR-020 work), flipped `DGR-024.passes` to `true` with `completionNotes`, regenerated the issue markdown, and rewrote the evidence README with exact commands/outputs. All quality gates (11/11 + 108/108 PRD-schema tests, compileall, `git diff --check`) pass.

+[09:23:17] [INFO] [agent] This is well-scoped: one concern per patch, chained blob assumptions, and explicit upstream API assumptions. This satisfies the "record upstream file/API assumptions and fail with the first incompatible patch" criterion — I confirmed the mechanism (`_check_assumption_blobs`) runs live during my `apply` test above. All five criteria check out against real code and a real live re-run. Let me also confirm PATCH-STACK.md documents this properly.

Per that pattern, I should restore them from HEAD before touching anything else in this file.

+[09:25:42] [INFO] [agent] ## Summary
+[09:25:42] [INFO] [agent] DGR-028's patch-stack implementation was already fully built and committed (`7da90ef`) from a prior session, but `prd.json` still had `passes: false`. Per the mandate to distrust legacy pass states, I independently re-verified it against live source rather than accepting that:
+[09:25:42] [INFO] [agent] - Confirmed all five patches' SHA256SUMS, the `UPSTREAM-ASSUMPTIONS.json` blob/API bindings, and control-plane/license boundary checks.
+[09:25:42] [INFO] [agent] - Live-ran `verify`/`apply`/`reverse` against the real cached `e920c523...` upstream checkout — apply produced the exact locked patched tree, reverse restored the pristine pin. `tests/test_llama_cpp_dependency.py` (7 passed), `compileall`, and `git diff --check` all clean.
+[09:25:42] [INFO] [agent] - Honestly noted the one gap: `cmake` isn't installed in this environment, so the prior session's native CTest claim couldn't be re-executed here (not re-confirmed, not retracted).
+[09:25:42] [INFO] [agent] - Found (again) the known `prd.json` top-level-field-drop bug, this time with other stories' legitimate uncommitted `passes`/`completionNotes` updates also in the working tree — did a targeted field-level restore from `HEAD` instead of overwriting the whole file, then set `DGR-028.passes = true` and regenerated its issue Markdown.
+[09:25:42] [INFO] [agent] Changed: `evidence/DGR-028/README.md`, `prd.json`, `issues/028-...md`, and `.ralph-tui/progress.md` (gitignored). No source/test edits needed — nothing left uncommitted was reverted, and pre-existing unrelated work (DGR-019/020/026 evidence, split_gguf, dgr_performance) was preserved untouched.

+[09:42:03] [INFO] [agent] Everything checks out. All acceptance criteria for DGR-029 are met and verified live:
+[09:42:03] [INFO] [agent] **Summary:**
+[09:42:03] [INFO] [agent] - Formalized the native CMake skeleton/CPU lane that partially existed but was never proven (DGR-028's `build()`/`smoke()`/`reproduce()` had no cmake in that session and no test coverage).
+[09:42:03] [INFO] [agent] - Locked an explicit CPU-only configure (`GGML_CPU=ON`; CUDA/HIP/Vulkan/Metal/BLAS all forced `OFF`) in `UPSTREAM_LOCK.json`, added a `ctest_lane()`/`ctest` CLI command running the deterministic model-free `test-meshnet-range-ownership` fixture via CTest, and fixed `reproduce()` to reverse the patch stack afterward (previously left the cache permanently patched, breaking reuse).
+[09:42:03] [INFO] [agent] - Live-verified end-to-end: fresh out-of-tree build (~2m16s) → smoke → CTest 1/1 passed → source restored to the exact pristine pin. Confirmed only CPU `ggml` backend libraries were produced, and confirmed an actionable failure (`cmake is unavailable; set CMAKE...`) when the toolchain is missing.
+[09:42:03] [INFO] [agent] - Installed `cmake` via pip into the existing repo-root `.venv` (no system-wide package install) since neither ambient Python nor `.venv-rocm` had it.
+[09:42:03] [INFO] [agent] - Added two new pytest tests (117 total pass): one offline shape check, one `cmake`-gated wiring test using a fast synthetic CMake project.
+[09:42:03] [INFO] [agent] - Repaired the recurring `prd.json` top-level field-drop bug, marked `DGR-029.passes = true`, regenerated the issue file, and wrote `.scratch/distributed-gguf-runtime/evidence/DGR-029/README.md`.

+# Architecture Deepening
+
+## Goal
+
+Increase depth, locality, and testability in the existing Meshnet runtime without changing its domain behavior or reopening accepted architecture decisions.
+
+## Scope
+
+This feature backlog is derived from the Graphify code graph and the architecture review. It targets three high-coupling modules:
+
+1. Distributed Route Session execution in the node HTTP path.
+2. Node startup orchestration.
+3. Tracker request intake and HTTP dispatch.
+
+## Constraints
+
+- Preserve ADR-0009: the Tracker is the control plane and public proxy; workers own tokenizer and model execution.
+- Preserve the active Distributed GGUF Runtime plan: DGR-040 owns native-worker supervision; DGR-041 owns native capability registration. Do not duplicate or redesign those stories.
+- Preserve existing Transformers behavior and backend-agnostic Tracker routing, billing, admission, telemetry, and relay semantics.
+- Each task starts with focused characterization tests, then moves behavior behind one deep module interface.
+
+## Order
+
+1. Route Session execution, because it has the clearest seam and lets distributed execution be tested without HTTP.
+2. Node startup orchestration, using the existing capability-validator adapters.
+3. Tracker intake, only after the first two establish the preferred deep-module style.

+# AD-001: Deepen Route Session execution behind one node seam
+
+- **Status:** needs-triage
+- **Priority:** p0
+- **Dependencies:** none
+- **Blocks:** AD-002
+- **Evidence:** Graphify identifies `torch_server.py` as the Activation Transport & Binary Frames hub; `_TorchHandler._do_chat_completions` has cyclomatic complexity 53 and owns request parsing, complete-model generation, distributed prefill/decode, Hot KV State recovery, transport clients, SSE, telemetry, and cleanup.
+
+## Objective
+
+Move distributed Route Session execution behind one deep module interface so the HTTP module only translates a client request into a Route Session result/stream.
+
+## Constraints
+
+- Preserve ADR-0009: the head worker owns tokenization and shard execution.
+- Preserve the existing OpenAI-compatible HTTP/SSE behavior.
+- Keep Hot KV State local to each shard and retain cache-miss re-prefill behavior.
+- Do not introduce native GGUF worker work; DGR-040 and DGR-041 own that scope.
+
+## Acceptance criteria
+
+- [ ] Characterization tests cover prefill, decode, cache-miss re-prefill, cancellation, and cleanup through the new module interface without an HTTP server.
+- [ ] The HTTP module retains only request translation, response translation, and request accounting.
+- [ ] Route Session lifecycle owns downstream direct/relay client cleanup in one place.
+- [ ] Existing two-node, KV-cache, relay, and OpenAI compatibility tests retain behavior.
+- [ ] `pytest` targeted tests and `python -m compileall packages tests` pass.
+
+## Likely files
+
+- Modify: `packages/node/meshnet_node/torch_server.py`
+- Create: module adjacent to `torch_server.py` for Route Session execution
+- Modify/add: `tests/test_two_node_pipeline.py`, `tests/test_kv_cache_distributed.py`, focused new tests
+
+## Non-goals
+
+No change to public route selection, model architecture behavior, native worker protocol, or WAN KV migration.

+# AD-002: Deepen Node startup orchestration

+- **Status:** needs-triage
+- **Priority:** p1
+- **Dependencies:** AD-001
+- **Evidence:** `run_startup()` in `packages/node/meshnet_node/startup.py` has cyclomatic complexity 101, a broad caller-facing parameter surface, and coordinates hardware, wallet, assignment, artifacts, server construction, capability proof, and Tracker registration.
+
+## Objective
+
+Create a deep Node startup module with explicit immutable startup intent and one execution seam, so callers and tests do not need to understand the full startup sequence.
+
+## Constraints
+
+- Retain the existing explicit capability-validator adapter used by tests.
+- Preserve current CLI behavior, registration data, startup ordering, and Transformers behavior.
+- Keep native-worker supervision out of scope: DGR-040 owns it. The result may expose a phase where DGR-040 can later attach, but must not implement that worker supervision.
+
+## Acceptance criteria
+
+- [ ] Characterization tests pin successful startup, capability refusal before registration, assignment behavior, and failure classification.
+- [ ] The public startup interface accepts a cohesive intent/plan rather than leaking orchestration details across callers.
+- [ ] Hardware/assignment, artifact/server, and proof/registration behavior are internally ordered and individually testable through internal seams.
+- [ ] Existing `tests/test_node_startup.py`, `tests/test_node_admission.py`, and mining CLI tests retain behavior.

+# AD-003: Deepen Tracker request intake without changing control-plane semantics
+
+- **Status:** needs-triage
+- **Priority:** p1
+- **Dependencies:** AD-001, AD-002
+- **Evidence:** Graphify marks `_TrackerHandler` as the highest-degree node (93 edges). `do_POST` dispatches auth, accounts, billing, registry, raft, gossip, placement, calibration, model, and inference paths; `do_GET` mixes operational projections and public request paths. Major handlers include proxy chat (CC 127), registration (CC 82), models (CC 43), and network assignment (CC 42).
+
+## Objective
+
+Deepen Tracker request intake around existing domain seams so HTTP dispatch stays thin and request-specific policy no longer leaks across unrelated control-plane workflows.
+
+## Constraints
+
+- Preserve ADR-0009: Tracker remains a control plane and public inference proxy, never a model host.
+- Preserve coverage-first assignment, billing, admission, relay, telemetry, Raft, and existing endpoint contracts.
+- Do not create a speculative adapter: each new seam must have at least two real callers/adapters or remain internal.
+
+## Acceptance criteria
+
+- [ ] Characterization tests pin all affected public endpoint response and error behavior before moving code.
+- [ ] HTTP dispatch delegates to cohesive intake modules for inference, node/registry lifecycle, and operator projections.
+- [ ] Route selection, billing attribution, admission, and coverage logic remain backend-agnostic and do not move into the HTTP module.
+- [ ] `_TrackerHandler` no longer owns unrelated endpoint policy directly.
+- [ ] Existing routing, capability-admission, billing, account, and consensus tests retain behavior.
+- [ ] `pytest` targeted tests and `python -m compileall packages tests` pass.
+
+## Likely files
+
+- Modify: `packages/tracker/meshnet_tracker/server.py`
+- Potentially modify: `packages/tracker/meshnet_tracker/billing.py`, `accounts.py`, `capability.py`, `recipe.py`
+- Modify/add: focused tests alongside `tests/test_tracker_routing.py`, `tests/test_tracker_capability_admission.py`, `tests/test_billing_ledger.py`, and `tests/test_tracker_consensus.py`

-# 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.
-
-Hard invariants:
-
-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.

+# GLM-5.2 Max distributed alpha roadmap
+
+Status: proposed executable epic target
+Last updated: 2026-07-13
+
+## Executive decision
+
+The alpha-release target is the exact open-weight model `zai-org/GLM-5.2` served with `reasoning_effort=max` from the smallest published Unsloth GGUF recipe, `UD-IQ1_S`, across multiple consumer machines.
+
+“Max” is a reasoning mode selected by the chat template/API request. It is not a separate model checkpoint.
+
+Alpha is earned only when the real target model:
+
+1. cannot fit within any one participating node's admitted memory;
+2. loads as contiguous layer Shards on at least two physical consumer machines;
+3. performs real GLM-5.2 MoE + DSA + IndexShare computation on every selected node;
+4. responds through the existing OpenAI-compatible Meshnet API with `reasoning_effort=max`;
+5. passes locked parity, usefulness, performance, telemetry, cancellation, and cleanup checks; and
+6. stores all model artifacts on configured mounted-drive storage, never under `/home`.
+
+The shortest safe path is not “support every GGUF architecture.” Dense Llama remains a small structural fixture. GLM-5.2 moves onto the critical path immediately after exact recipe identity and the pinned llama.cpp boundary. Qwen expansion, 1M context certification, MTP/speculative decoding, broad concurrency, and automatic route repair are post-alpha.

+Before downloading 216.7 GB, DGR-017 must generate a checked-in target manifest containing repository revisions, expected filenames, byte sizes, and resolved LFS SHA-256 values. Download is resumable and verified before route admission.
+
+`UD-IQ1_M` (228,492,966,624 bytes / 212.801 GiB) is the first diagnostic fallback if `UD-IQ1_S` exposes a runtime or quality defect. It does not satisfy the explicit “lowest quantization” alpha target unless the target contract is changed by human review.
+
+### 1.3 Runtime semantics required for alpha
+
+Required:
+
+- GGUF parsing and quantized kernels from one exact llama.cpp pin.
+- Correct GLM-5.2 MoE routing, selected experts, and shared expert.
+- Correct compressed MLA KV cache for locally owned layers.
+- Native DSA lightning indexer and sparse attention.
+- Correct IndexShare Full/Shared role execution from artifact metadata.
+- Range-owned contiguous transformer layers; each owned layer keeps all of its experts local.
+- Head-only embeddings and tail-only final norm/output head/sampling.
+- Architecture-defined activation boundary and optional DSA index sideband.
+- `reasoning_effort=max` chat-template behavior through the public API.
+- F32 seam correctness lane and a separately certified production activation dtype.
+
+Not required for alpha:
+
+- MTP/speculative decoding. The trailing NextN tensors may be loaded or explicitly excluded according to a certified recipe, but cannot be silently misinterpreted.
+- Full 1,048,576-token context.
+- Continuous batching beyond one target session.
+- Public-WAN tensor or expert parallel collectives.
+- Automatic mid-generation repair or KV migration.
+- Every CPU/GPU backend combination.
+
+## 2. Minimum resource envelope
+
+### 2.1 Weight and runtime memory
+
+The smallest artifact occupies 201.832 GiB before KV, DSA indexer state, scratch buffers, backend workspaces, process memory, and the operating system. **224 GiB aggregate runtime-accessible memory is only the experimental hard-fit floor**, consistent with Unsloth's approximate 223 GB one-bit requirement. It is not a conservative operational envelope.
+
+For admission, each node reserves:
+
+```text
+max(20% of physically usable memory, 8 GiB)
+```
+
+The remainder is the combined weight-plus-KV placement budget. Actual peak scratch is measured by backend/context and can force one extra node. Unified memory is counted once: integrated-GPU “VRAM” must not be added again to the same physical system RAM.
+
+| Physical usable tier | Minimum reserve | Weight + KV placement budget | IQ1_S 16K arithmetic minimum | Operational position |
+|---:|---:|---:|---:|---|
+| 32 GiB | 8.0 GiB | 24.0 GiB | 9 nodes | use 10 if attempted; latency-heavy |
+| 48 GiB | 9.6 GiB | 38.4 GiB | 6 nodes | possible; latency-heavy |
+| 64 GiB | 12.8 GiB | 51.2 GiB | 4 nodes | hard minimum; **5 recommended** |
+| 96 GiB | 19.2 GiB | 76.8 GiB | 3 nodes | recommended |
+| 128 GiB unified/system | 25.6 GiB | 102.4 GiB | 2 nodes | arithmetic hard minimum; **3 recommended** |
+
+The planner must use exact tensor byte ownership, not equal percentages. Embeddings, final head, dense versus MoE layers, shared experts, indexer tensors, quant block alignment, KV distribution, and backend workspace make equal layer counts unequal in memory.
+
+Recommended first target route: **three 96/128-GiB-class physical machines** or **five 64-GiB-class machines**, on the same wired switch with mounted model storage. Four 64-GiB or two 128-GiB machines are fit probes only and qualify solely if exact placement and measured peak-memory evidence retain the required reserve with no swap/overcommit.
+
+### 2.2 KV cache
+
+GLM-5.2 MLA caches 576 latent/rope values per token per backbone layer. Correct DSA also caches 128-dimensional indexer keys: ideally only for the 21 Full indexer layers, while the current experimental implementation may allocate them across all 78 layers. Alpha locks **Q8_0 KV** for quality and budgets the conservative current-implementation layout.
+
+| Context × concurrency | MLA-only Q8 | Optimized DSA Q8 | Conservative current-DSA Q8 | Conservative current-DSA F16 |
+|---:|---:|---:|---:|---:|
+| 16,384 × 1 | 0.73 GiB | 0.77 GiB | **0.89 GiB** | 1.68 GiB |
+| 131,072 × 1 | 5.83 GiB | 6.18 GiB | **7.12 GiB** | 13.41 GiB |
+| 1,048,576 × 1 | 46.62 GiB | 49.41 GiB | **56.98 GiB** | 107.25 GiB |
+
+These are planning estimates, not admission truth. The runtime must report measured allocated/resident MLA and indexer cache by Shard. Alpha configures a 16,384-token window, Q8_0 KV, and one session. Longer contexts and lower-bit KV are separate quality/resource certification gates.
+
+### 2.3 Activation seams and network
+
+A BF16 hidden-state boundary is 6,144 elements = 12,288 bytes/token before framing.
+
+- A 16,384-token prefill sends about 192 MiB per seam.
+- One decode token sends about 12 KiB per seam.
+- A 512-token decode sends about 6 MiB per seam.
+- Four nodes imply three serial seams.
+
+If a Shard boundary splits an IndexShare producer/consumer group, a 2,048-entry int32 top-k sideband can add up to 8 KiB/query before framing. The route planner should prefer boundaries that preserve complete IndexShare ownership groups. The protocol must still support and validate the named sideband because memory fit may force an internal group split.
+
+Decode bandwidth is small, but every generated token crosses all seams serially, so node count and per-hop latency dominate. Alpha requires a same-switch wired route: **2.5 GbE minimum and 10 GbE recommended**, with measured one-way/RTT, serialization, and queue latency. A 1 GbE route may be retained as fit-only evidence but is not the recommended alpha topology. Alpha records per-seam bytes, p50/p95 transfer latency, retries, and checksum failures; no speed claim is inferred from link rate alone.
+
+### 2.4 Storage
+
+The shortest alpha path allows every node to hold the complete six-file source GGUF while mapping/allocating only owned tensors. This minimizes artifact-transformation risk but costs 216.7 GB disk per node.
+
+Deterministic source-bound layer packages are a follow-up optimization. If needed before target fit, every package must retain:
+
+- source repository/revision and source file hashes;
+- exact owned tensor names, layer range, and endpoint role;
+- tokenizer/config identity;
+- deterministic package hash; and
+- proof that composing all packages matches the source tensor inventory.
+
+## 3. Current state and critical gaps
+
+### Completed foundation
+
+- DGR-001: immutable CPU contract plus separate signed ROCm diagnostic. CPU v1 remains `stop`; the GPU diagnostic establishes a viable fit/performance investigation lane but does not rewrite CPU evidence.
+- DGR-002: versioned backend-neutral gRPC/Protobuf Shard protocol with bounded fragments and compatibility checks.
+- Existing Meshnet: Tracker, contiguous Shards, Route Sessions/epochs, relay/direct transport, local Hot KV semantics in the reference backend, cancellation, telemetry, billing, and model-agnostic admission.
+
+### Missing before target alpha
+
+1. Exact GLM target/artifact manifest and memory-fit planner.
+2. A current llama.cpp pin proven to load and generate with the exact `UD-IQ1_S` artifact.
+3. A narrow decision on native GLM-5.2 DSA/IndexShare support. As observed 2026-07-13, merged llama.cpp PR #24770 loads GLM-5.2 through a dense-MLA compatibility path, while full IndexShare/DSA PR #25407 remains open and its generic sparse path can be slower than dense fallback. Generic CPU lightning-indexer support is merged; backend coverage remains uneven.
+4. A decode protocol amendment. `ActivationChunk` carries `TensorBundle`, but the current `DecodeStep` fast path carries only one `NamedTensor`; it cannot transport a hidden state plus GLM top-k sideband. Tail token/logit and sampling behavior also needs an explicit typed result contract.
+5. Correct range-owned GGUF loading and memory proof.
+6. GLM-specific boundary/KV/IndexShare semantics.
+7. Standalone native worker and Meshnet integration.
+8. Real target hardware route with no node individually able to admit the whole model.
+9. Locked target parity, usefulness, speed, failure, and cleanup evidence.
+
+### Donor policy
+
+`Mesh-LLM/mesh-llm` is a high-value test and patch donor. Its live GLM branch was observed with 261 llama.cpp patches, 167 named for GLM/DSA/MTP-related work. That is evidence of the problem's depth, not an acceptable maintained fork boundary.
+
+Audit and selectively reproduce the smallest independently understood pieces for:
+
+- GLM DSA graph semantics;
+- lightning indexer and sparse-attention tests;
+- IndexShare metadata/Full/Shared validation;
+- top-k sideband shape and lifecycle;
+- stage-local KV filtering; and
+- target parity/performance fixtures.
+
+Do not import Mesh-LLM routing, discovery, scheduler, public mesh, package manager, or full patch stack. Keep Meshnet as the sole control plane and collaborate narrowly upstream with llama.cpp/Mesh-LLM maintainers where practical.
+
+## 4. Revised roadmap
+
+## Phase 0 — lock the target before implementation
+
+### DGR-017: lock GLM-5.2 Max target and alpha contract
+
+Deliver:
+
+- machine-readable target manifest for official and GGUF revisions;
+- exact `UD-IQ1_S` file/size/hash inventory;
+- architecture/config/chat-template snapshot;
+- memory/KV/network planner with unified-memory de-duplication;
+- immutable alpha acceptance thresholds from section 5; and
+- current upstream/donor status report.
+
+Exit: target identity and alpha requirements are reviewable without downloading the model.
+
+## Phase 1 — establish a correct whole-model oracle
+
+### DGR-003: exact runtime recipe identity
+
+Extend the existing generic identity with GLM fields: DSA/IndexShare metadata, adapter version, reasoning template revision, activation bundle schema, KV dtype/layout, llama.cpp pin/patch hash, and target artifact manifest hash.
+
+### DGR-004: reproducible llama.cpp pin and narrow patch boundary
+
+Select a current exact upstream commit only after testing its stock GLM behavior. Add clean fetch/apply/build checks. Record every donor patch and whether it is adopted, rewritten, rejected, or waiting upstream.
+
+### DGR-018: certify whole-model GLM-5.2 runtime semantics
+
+On a 256-GiB-class reference host with at least 224 GiB runtime-accessible memory after OS reservation, or a measured equivalent:
+
+1. verify all six `UD-IQ1_S` shards;
+2. load with a stock pinned runtime and capture tensor/metadata warnings;
+3. prove whether DSA, IndexShare, shared expert, and Max template are actually active;
+4. add the minimum correctness patches/tests required;
+5. run deterministic prefill/decode and fixed Max-mode sentinel prompts; and
+6. sign the oracle recipe, output, telemetry, and limitations.
+
+Exit: one whole-model oracle exists for the same artifact/runtime semantics the distributed path will implement. “It emits text” is insufficient.
+
+## Phase 2 — build the generic local seam using small fixtures
+
+### DGR-005: range-owned GGUF tensors
+
+Keep dense Llama as a cheap structural fixture. Implement authoritative owned-tensor registration/loading, head/tail ownership, and measured resident-memory scaling. Design tensor classification so GLM adds explicit rules rather than unchecked name substitution.
+
+### DGR-006: architecture-defined boundary
+
+Implement named boundary bundles, F32 correctness lane, bounded fragmentation, and optional sidebands. Amend the decode fast path so it carries a versioned `TensorBundle` rather than one `NamedTensor`, while preserving a small one-tensor encoding. Define an explicit typed tail result for logits/token output and bind sampling/chat-template parameters to the recipe/request. Regenerate Python/C++ schema code and compatibility goldens. Dense fixture parity proves the seam mechanism, not GLM certification.
+
+Exit: two local processes can execute a small dense model with correct range ownership and boundary parity.
+
+## Phase 3 — add GLM-5.2 as the product adapter
+
+### DGR-019: implement and certify GLM-5.2 range/DSA/IndexShare semantics
+
+Deliver explicit support for:
+
+- 78 main layers and endpoint tensor ownership;
+- 256-expert MoE routing/top-8 and shared expert;
+- compressed MLA KV by owned layers;
+- DSA lightning indexer and sparse attention;
+- IndexShare metadata, Full producer, Shared consumer, and sideband behavior;
+- NextN/MTP tensor policy with MTP disabled or enabled explicitly;
+- shard-boundary planner aware of IndexShare ownership groups; and
+- whole-model versus two-stage parity against DGR-018.
+
+Exit: a same-host two-stage target run matches the locked oracle tolerance with real GLM computation in both stages. If the full target cannot fit on one host for this check, use a layer-reduced GLM architecture fixture for graph parity and defer full-artifact output parity to DGR-020; label the distinction explicitly.
+
+## Phase 4 — worker, KV, and Meshnet route
+
+Execute existing stories with GLM requirements included:
+
+1. DGR-007 — isolated local Hot KV keyed by `(Route Session, epoch)`, including DSA/IndexShare state.
+2. DGR-008 — standalone C++ gRPC worker.
+3. DGR-009 — Meshnet backend, capability, relay/direct, cancellation, and telemetry integration.
+4. DGR-010 — small-model local two-process acceptance.
+5. DGR-011 — real two-physical-machine route and heterogeneous fail-closed behavior.
+6. DGR-013 subset required by alpha — node loss, cancellation, stale epoch, restart, and memory/KV cleanup.
+
+Continuous batching (DGR-012) is deliberately not an alpha dependency. The first target release supports one admitted GLM route session; concurrency follows after target correctness and fit.
+
+## Phase 5 — target alpha gate
+
+### DGR-020: pass real distributed GLM-5.2 Max alpha acceptance
+
+Use at least two physical machines and enough aggregate usable memory to meet the locked target planner. No participating node may individually admit the complete target. All stages must report real compute and exact tensor ownership.
+
+Run the complete acceptance matrix in section 5, preserve raw logs/metrics/output, sign the evidence, and publish an explicit `alpha` or `stop` verdict. Thresholds cannot be weakened after results are known.
+
+## Phase 6 — post-alpha hardening
+
+After DGR-020 passes:
+
+1. DGR-012 — 1/2/4-session continuous batching and bounded admission.
+2. DGR-014 — final distributed GGUF versus reference-route performance decision.
+3. 32K, 128K, 200K, then 1M context certification with quantized KV.
+4. MTP/speculative decoding.
+5. Deterministic range packages to remove full-artifact replication.
+6. Additional backend compatibility classes and route topologies.
+7. DGR-016 — narrow upstream collaboration package, split by independently reviewable llama.cpp changes.
+8. DGR-015 — Qwen3/Qwen3-MoE only as later architecture expansion, not as the GLM alpha target.
+
+## 5. Locked alpha acceptance matrix
+
+These thresholds are set before target execution.
+
+### 5.1 Identity and fit
+
+- Exact official and GGUF repository revisions match the target manifest.
+- All six source GGUF sizes and LFS SHA-256 values verify.
+- Every route node reports owned tensor names/bytes, layer range, endpoint role, backend, KV recipe, and patch fingerprint.
+- Union of owned tensors equals the certified runtime-required tensor inventory; unintended overlap is zero.
+- No node's weight-plus-KV placement budget can hold the complete recipe.
+- Every node reserves at least `max(20% of physically usable memory, 8 GiB)` outside weight-plus-KV placement; measured peak scratch must remain inside that reserve.
+- Aggregate peak RSS/VRAM stays within physical budgets with no swap, overcommit, mmap-only, or double-counted unified-memory success claim.
+- Arithmetic-minimum topologies require exact contiguous tensor placement evidence; recommended alpha topology is 5×64 GiB or 3×96/128 GiB.
+- Unified RAM/VRAM is not double-counted.
+
+### 5.2 Semantic correctness
+
+- Logs and graph tests prove GLM MoE/shared-expert, DSA lightning indexer, sparse attention, and IndexShare Full/Shared paths are active; dense-attention compatibility fallback cannot satisfy alpha.
+- `reasoning_effort=max` is observable in the rendered template/API recipe.
+- F32 same-backend seam fixture: 32 greedy decode tokens exactly match the whole-model oracle and activation tolerance is locked by DGR-006.
+- Production seam on the fixed prompt corpus: greedy token agreement is at least 0.90 and mean compared-state/logit cosine similarity is at least 0.999 versus DGR-018, with no malformed or non-finite tensors.
+- Incompatible artifact, tokenizer, adapter, DSA metadata, boundary, activation, KV, backend class, or runtime patch fingerprints fail closed.
+
+### 5.3 End-to-end target run
+
+- Context configured to 16,384 tokens with Q8_0 MLA/indexer KV.
+- Fixed 4,096-token prompt lane completes prefill.
+- Route uses a same-switch wired network; 2.5 GbE is the alpha minimum and 10 GbE is recommended.
+- One Max-mode request generates at least 512 output tokens or reaches a valid natural EOS after at least 128 tokens.
+- Fixed coding, structured tool-call/JSON, and multi-step reasoning sentinels produce parseable, relevant outputs; raw prompts and outputs are retained for review.
+- OpenAI-compatible response includes stable model ID, finish reason, and token usage.
+
+### 5.4 Minimum useful performance
+
+On the declared minimum alpha topology after one warm-up:
+
+- median decode throughput is at least 0.5 generated token/s for the fixed Max-mode lane;
+- 4,096-token-prompt TTFT is at most 10 minutes;
+- no unexplained stall exceeds 60 seconds without progress telemetry;
+- per-stage compute, queue, KV, seam bytes/latency, RSS/VRAM, and backend timing are present; and
+- results are labeled by hardware/topology and are not generalized to other consumer systems.
+
+If output quality passes but the speed floor fails, verdict is `stop` for alpha and the evidence selects the next optimization target. It is not relabeled as success merely because the model loaded.
+
+### 5.5 Reliability and security
+
+- Two consecutive cold starts load, generate, release, and exit cleanly.
+- Cancellation during prefill and decode releases every stage's queued buffers and KV lease.
+- One worker loss aborts the route; alpha retries only from token zero on a new compatible route.
+- Stale epochs and duplicate step IDs are rejected.
+- Artifact paths stay outside `/home`; logs contain no secrets or unrestricted prompt payloads.
+- Synthetic workers and layer-reduced fixtures are labeled unit/integration coverage and cannot satisfy target alpha.
+
+## 6. First execution order
+
+The next unattended work should run in this order:
+
+1. DGR-017 — target contract, manifest, planner, and upstream status.
+2. DGR-003 — exact recipe identity.
+3. DGR-004 — current llama.cpp pin and minimal patch harness.
+4. Run in parallel:
+   - DGR-018 — whole-model oracle on a 256-GiB-class host with at least 224 GiB runtime-accessible memory.
+   - DGR-005 and DGR-006 — generic range/boundary seam on local small fixtures.
+5. DGR-019 — GLM semantics and parity after both parallel lanes pass.
+6. DGR-007 through DGR-011 — native worker and real transport route.
+7. Required DGR-013 failure subset.
+8. DGR-020 — real target alpha verdict.
+
+The first external hardware blocker is DGR-018, but DGR-005/DGR-006 proceed locally while that host is sourced. Do not download the full model until DGR-017's exact manifest and storage preflight pass.

 # PRD: Distributed GGUF Runtime
 
-## Summary
+> **Specification status:** planning artifacts only. No distributed GGUF runtime is implemented. DGR-017 cleanup is complete; no runtime implementation story has completion credit. `prd.json` is authoritative.
 
-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.
+## Goal
 
-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.
+Deliver benchmark-gated, concurrent, distributed GGUF inference across consumer machines through existing Meshnet control-plane behavior and a standalone native worker around upstream llama.cpp. The accepted target is DeepSeek V4 Flash, not the superseded legacy target.
 
-## Goals
+## Locked scope
 
-- Eliminate full-prompt recompute in distributed decode.
-- Keep decode activation seams proportional to `hidden_size`, not `context_length * hidden_size`.
-- Keep Hot KV State local to the node serving the relevant Shard.
-- Stream token deltas when feasible and always expose Generation Telemetry.
-- Add a local full-model GGUF backend for immediate CPU performance wins.
-- Define Model Artifact manifests so nodes can verify, seed, and advertise artifacts without depending on Hugging Face at request time.
-- Prototype an upstreamable llama.cpp/libllama layer-boundary API.
-- Use DeepSeek-V4-Flash as the first serious large-model target after smaller protocol smoke tests.
+- Existing Meshnet Tracker routing, load balancing, billing, telemetry, relay, and provider semantics are backend-agnostic and are **not redesigned**. GGUF contributes exact compatibility, range/capacity, queue/load, seam-cost, health/reliability, and certification inputs only.
+- The data plane is a standalone project-owned C++ Shard worker with gRPC/Protobuf and a project-owned `ShardEngine` boundary.
+- llama.cpp is fetched at one exact commit into an ignored workspace from an in-repo manifest, then a numbered minimal patch stack is applied. There is no submodule, vendored tree, or permanent-fork dependency.
+- llama.cpp owns DeepSeek V4 graphs, mHC, MoE, attention, hash routing, and kernels. Meshnet adds only range-ownership hooks, typed boundary/local-state adapters, worker integration, and parity/certification.
+- Quantization and placement are dynamic recipe inputs. The 2–4 and 10+ stage layouts are certification scenarios, never product constants.
+- Per-shard Hot KV and V4 CSA/HCA/SWA/indexer/compressor state remain local and keyed by route session/epoch. The WAN seam carries the typed mHC 4×4096 residual boundary, positions, token-ID sideband where required, and schema/cache expectations—not per-layer caches.
+- Route changes use cache miss plus re-prefill/restart. There is no WAN KV or V4 auxiliary-cache migration.
+- CPU/CUDA/ROCm/Vulkan/Metal compile lanes are planned; only exact real-hardware-certified backend/model/recipe lanes may be advertised.
+- Alpha requires correctness and the pre-locked useful-speed gate. MTP is reserved and off for alpha; its ownership contract, implementation, and benchmark are required before beta.
 
-## Non-Goals
+## Target identities
 
-- No centralized hot KV cache in the per-token decode path.
-- No automatic route repair in alpha.
-- No permanent llama.cpp fork as the intended architecture.
-- No GLM-5.2 or Ornith first; they remain follow-up support audits.
-- No transport rewrite to QUIC/WebRTC before route/session semantics are proven.
+- DeepSeek V4 official target SHA: `60d8d70770c6776ff598c94bb586a859a38244f1`.
+- llama.cpp V4 support lineage began at PR 24162 / merge `8c146a8366304c871efc26057cc90370ccf58dad`; DGR-027 later pins one exact validated current commit.
+- V4 scope: 43 main layers plus MTP; mHC 4×4096 boundary; 256 routed + 1 shared experts with six routed active; token IDs required for the first three hash-routed layers.
+- Exact split-GGUF artifacts are provisioned to mounted-drive storage with a complete hashed manifest and resumable verification; no model artifact may be placed under `/home`.
 
-## Resolved Decisions
+## Quality gates
 
-- Public-network Shards are contiguous transformer layer ranges.
-- Tensor/ring parallelism belongs inside one trusted node, one colocated pod, or a future composite node abstraction.
-- Hot KV State is local to route nodes; Prefix Snapshots are optional cold recovery/reuse artifacts.
-- PyTorch distributed KV/session semantics are proven before llama.cpp distributed execution.
-- Streaming responses are preferred; Generation Telemetry is mandatory.
-- 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
-
-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.
-
-If a route node drops in alpha, the request fails clearly. A retry starts a new Route Session from scratch.
-
-## 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
-```
+The canonical gate groups live in `prd.json`. Every story explicitly requires its applicable shared gates: deterministic targeted tests, Python compile checks where applicable, native CMake/CTest and exact patch verification where applicable, real artifact/hardware provenance for opt-in lanes, `git diff --check`, and a durable evidence handoff.

-## Acceptance Criteria
+## User stories
 
-- 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.

Inspect live source/tests rather than trusting legacy pass states. Objective: Demonstrate that a large real route can be dynamically selected and usefully execute V4.
+
+- [ ] Run one real 10+-stage V4 certification scenario; stage count, quant, and split remain scenario metadata only.
+- [ ] Every selected stage proves real work, exact compatible identity, local state ownership, and bounded resources.
+- [ ] Record end-to-end and per-stage TTFT, prefill/decode, seam cost, queueing, memory, failures, and cleanup.
+- [ ] Inject at least one incompatible or degraded candidate and verify dynamic exclusion/reselection.

+
+- [ ] Profile worker compute, tensor conversion, copies, protobuf framing, compression, relay/direct transport, queueing, and synchronization.
+- [ ] Select one dominant bottleneck from evidence and lock its before/after benchmark.
+- [ ] Implement one bounded optimization without weakening correctness or protocol identity.

Inspect live source/tests rather than trusting legacy pass states. Objective: Reduce V4 seam cost only when a certified compression recipe improves end-to-end performance acceptably.
+
+- [ ] Negotiate compression through recipe identity; unnegotiated or mismatched compression fails closed.
+- [ ] Preserve names, shapes, semantic axes, token-ID sideband, and checksums.
+- [ ] Measure quality drift, encode/decode cost, bytes, TTFT, and throughput against uncompressed boundaries.

Inspect live source/tests rather than trusting legacy pass states. Objective: Lock MTP tensor, execution, boundary, acceptance/rejection, and session-state ownership before implementation while keeping MTP disabled for alpha.
+
+- [ ] Derive exact MTP tensor and execution ownership from the pinned V4 target and upstream llama.cpp graph, distinguishing main-layer, tail, and MTP responsibilities.
+- [ ] Define typed MTP inputs/outputs plus accepted-token, rejection, rollback/truncation, position, cache, and session/epoch lifecycle semantics.
+- [ ] Specify which MTP state remains shard-local and which typed boundary values cross a seam; prohibit WAN migration of KV or V4 auxiliary caches.

Inspect live source/tests rather than trusting legacy pass states. Objective: Implement the locked MTP contract around upstream llama.cpp before beta, without making MTP an alpha prerequisite.
+
+- [ ] Implement the exact DGR-065 MTP ownership and typed state contract against the pinned upstream V4 graph while preserving shard-local caches.
+- [ ] Pass whole-model versus ranged MTP correctness, accepted-token, rejection, rollback/truncation, and session-isolation tests.
+- [ ] Benchmark MTP-off versus MTP-on quality, accepted-token rate, TTFT, decode speed, seam bytes, and memory on the locked lane.

Inspect live source/tests rather than trusting legacy pass states. Objective: Publish only backend/model/recipe lanes proven on actual CPU, CUDA, ROCm, Vulkan, or Metal hardware.
+
+- [ ] Maintain independent build and certification status for CPU, CUDA, ROCm, Vulkan, and Metal.
+- [ ] Each advertised lane includes real hardware/driver/runtime/model evidence for parity, concurrency, cancellation, cleanup, and useful speed.
+- [ ] Build success alone never makes a lane routable; unavailable hardware remains explicitly dark.
+- [ ] Tracker admission consumes signed/versioned certification records rather than backend-name allowlists.

Inspect live source/tests rather than trusting legacy pass states. Objective: Reduce long-term patch burden through generic upstreamable hooks without asking llama.cpp to own Meshnet.
+
+- [ ] Separate generic range loading, boundary I/O, and filtered state hooks from project worker/protocol code.
+- [ ] Provide one scoped patch, focused test, and minimal reproducer per concern against the exact upstream pin.
+- [ ] Compare the proposal with prior-art evidence and current upstream V4 support/maturity.

+
+- [ ] Evaluate all beta metrics against DGF-004 without changing thresholds after observing results.
+- [ ] Require V4 parity, batching/fairness, bounded backpressure, failure recovery, long-context correctness, MTP evidence, and dynamic 10+ stage evidence.

+
+- [ ] Add a documented update procedure for llama.cpp pin, numbered patches, protocol/engine versions, V4 target revision, and certification records.
+- [ ] A candidate pin update must apply/build/test in isolation and cannot replace the production pin automatically.

+
+## Mandatory startup for every fresh story
+
+1. Read this file and authoritative `prd.json` completely.
+2. Read the generated source issue named in the selected story description.
+3. Read every dependency evidence README; legacy DGR-001..016 evidence is provenance only.

+5. Inspect `git status`; preserve unrelated work. Never infer implementation from planning text or old pass states.
+6. If blocked or oversized, keep `passes: false` and write an honest `BLOCKED.md`/`DECOMPOSITION.md`; never weaken criteria or fabricate evidence.
+
+## Locked scope
+
+- Existing Meshnet Tracker routing, load balancing, billing, telemetry, relay, and provider semantics are backend-agnostic and are **not redesigned**. GGUF contributes exact compatibility, range/capacity, queue/load, seam-cost, health/reliability, and certification inputs only.
+- The data plane is a standalone project-owned C++ Shard worker with gRPC/Protobuf and a project-owned `ShardEngine` boundary.
+- llama.cpp is fetched at one exact commit into an ignored workspace from an in-repo manifest, then a numbered minimal patch stack is applied. There is no submodule, vendored tree, or permanent-fork dependency.
+- llama.cpp owns DeepSeek V4 graphs, mHC, MoE, attention, hash routing, and kernels. Meshnet adds only range-ownership hooks, typed boundary/local-state adapters, worker integration, and parity/certification.
+- Quantization and placement are dynamic recipe inputs. The 2–4 and 10+ stage layouts are certification scenarios, never product constants.
+- Per-shard Hot KV and V4 CSA/HCA/SWA/indexer/compressor state remain local and keyed by route session/epoch. The WAN seam carries the typed mHC 4×4096 residual boundary, positions, token-ID sideband where required, and schema/cache expectations—not per-layer caches.
+- Route changes use cache miss plus re-prefill/restart. There is no WAN KV or V4 auxiliary-cache migration.
+- CPU/CUDA/ROCm/Vulkan/Metal compile lanes are planned; only exact real-hardware-certified backend/model/recipe lanes may be advertised.
+- Alpha requires correctness and the pre-locked useful-speed gate. MTP is reserved and off for alpha; its ownership contract, implementation, and benchmark are required before beta.
+
+## Target identities
+
+- DeepSeek V4 official target SHA: `60d8d70770c6776ff598c94bb586a859a38244f1`.
+- llama.cpp V4 support lineage began at PR 24162 / merge `8c146a8366304c871efc26057cc90370ccf58dad`; DGR-027 later pins one exact validated current commit.
+- V4 scope: 43 main layers plus MTP; mHC 4×4096 boundary; 256 routed + 1 shared experts with six routed active; token IDs required for the first three hash-routed layers.
+- Exact split-GGUF artifacts are provisioned to mounted-drive storage with a complete hashed manifest and resumable verification; no model artifact may be placed under `/home`.
+
+## Control/data-plane contract
+
+Meshnet continues to own registration, coverage, existing route selection/load balancing, route epochs/sessions, direct/relay behavior, capability admission, cancellation, telemetry, billing, validation, and attribution. The GGUF adapter exposes measured inputs to those existing mechanisms. Direct seams use long-lived gRPC streams; relay seams carry byte-identical protobuf frames opaquely.
+
+The project-owned `ShardEngine` hides llama.cpp internals. A worker loads one exact artifact/recipe/range identity. Default tests use fake/tiny fixtures. Real runs are opt-in, preserve raw metrics, and never download models under `/home`.
+
+## Gitea issue synchronization
+
+Gitea is a projection of `prd.json`, never a competing source of truth. Before and after every supervised Ralph run, invoke:
+
+```bash
+python3 scripts/ralph_gitea_sync.py sync
+```
+
+For a complete Ralph invocation with automatic state reconciliation, use:
+
+```bash
+scripts/ralph-gitea-run.sh ralph-tui run --prd .scratch/distributed-gguf-runtime/prd.json --agent claude --model sonnet --iterations 1 --no-tui --no-setup --direct-merge --no-sandbox
+```
+
+The sync creates/reconciles one Gitea issue per `DGR-*` story, creates missing labels/milestones, closes issues whose `passes` is true, marks the selected next eligible story `status:in-progress`, and marks blocked stories `status:blocked`. `gitea-issues.json` is a derived mapping only.
+
+## Evidence and completion
+
+Each story writes `/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/evidence/<DGR-ID>/README.md` with exact files, commands/results, limitations, identities, and dependent-story handoff. Only `prd.json` may record `passes`; DGR-017 and DGR-018 are complete and DGR-019 onward remain false. Generated Markdown and Gitea issues cannot override it. One scoped commit per story is expected during future execution.

-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.
 
-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.

-Adopt a hybrid runtime:
+## Navigation
 
-- **Weights and artifacts**: distributed by torrent / content-addressed storage / optional CDN.
-- **Hot KV cache**: local to the node that owns the corresponding layer range.
-- **Prefix snapshots**: optionally persisted to cache servers for reuse, retry, and failover.
-- **Active route**: sticky for one request/session.
-- **Context cap**: 128K hard product limit for large models unless explicitly revised.
-- **Backends**: keep PyTorch for fast model-architecture coverage and validation; add llama.cpp/GGUF as the performance path for supported models.
-- **Client feedback**: stream token deltas when feasible; always expose Generation Telemetry.
-- **First serious target model**: DeepSeek-V4-Flash after a smaller GGUF protocol smoke test.
-
-## What We Learned
-
-- Our current full-model PyTorch path uses Transformers `generate()` and gets local KV cache.
-- 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.

-## Open Questions
-
-- Does upstream llama.cpp already expose enough internal API for arbitrary layer-range execution and hidden-state boundary I/O, or do we need an extension?
-- 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?

-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.

-- **Full local PyTorch model**: calls Hugging Face `model.generate()`, so Transformers owns autoregressive decode and local KV cache.

-Current distributed data flow:
+- DeepSeek V4 official target SHA: `60d8d70770c6776ff598c94bb586a859a38244f1`.
+- llama.cpp V4 support lineage began at PR 24162 / merge `8c146a8366304c871efc26057cc90370ccf58dad`; DGR-027 later pins one exact validated current commit.

+## Topology
 
 ```text
-client request
-  -> head node formats prompt
-  -> for each output token:
-       head tokenizes full current text
-       head runs early layers over all tokens
-       head sends full activation [batch, sequence, hidden] to next node
-       middle nodes run their layers over all tokens
-       tail returns one decoded token string
-       head appends token to text
+existing Meshnet Tracker/control plane
+  -> existing backend-agnostic route/load-balancing decision
+  -> direct gRPC or existing opaque relay
+  -> project-owned standalone C++ Shard worker
+  -> project-owned ShardEngine
+  -> pinned upstream llama.cpp + numbered range/boundary/state hook patches
+  -> GGUF mmap, upstream V4 graph/kernels, local per-shard state
 ```
 
-This is correct for small demos but not viable for large models. For GLM-5.2, a single 128K seam activation is roughly:
+A route is ordered contiguous half-open ranges. Head owns token embedding; tail owns final norm/head/sampling. Compatibility fingerprints bind source/split hashes, tokenizer, architecture adapter, typed boundary, runtime pin/patches, backend, quant, activation/compute/KV layout, range, and certification.
 
-```text
-128K tokens * hidden_size 6144 * 2 bytes ~= 1.5 GiB per hop
-```
+## V4 boundary and state
 
-Sending that every output token is the bottleneck.
+The inter-stage boundary is semantic and versioned: mHC 4×4096 residual, positions, token IDs only where the first three hash-routed layers require them, and cache/schema expectations. CSA/HCA/SWA/indexer/compressor/KV state belongs to upstream layer execution on the owning worker and is isolated by `(route_session_id, route_epoch)`. On loss, return cache miss and re-prefill/restart. Never serialize those caches into the WAN bundle.
 
-## Target State
+## Concurrency, failure, and admission
 
-Target distributed data flow:
-
-```text
-client request
-  -> tracker selects route and pins session
-  -> head node creates session_id
-  -> prefill:
-       prompt is chunked
-       each shard computes its layer range
-       each shard appends local KV/state for its own layers
-       activations cross only layer seams
-  -> decode loop:
-       head sends one new token / one-step hidden state
-       each shard reads local KV/state for session_id
-       each shard appends one step to local KV/state
-       only one-step activation crosses seams
-       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.
-
-## Client Feedback
-
-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.
-
-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.
-
-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
-  -> produces model manifest
-  -> creates GGUF / safetensors / tokenizer artifacts
-  -> content-addresses every file/chunk
-  -> publishes torrent/magnet + HTTP fallback metadata
-
-node
-  -> chooses model/layer range
-  -> downloads needed files/chunks
-  -> verifies hash
-  -> advertises availability to tracker
-```
-
-Required manifest fields:
-
-- model id and version
-- 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
-
-The tracker selects routes using layer coverage and observed performance:
-
-```text
-route = [
-  head node: embeddings + layers 0..k
-  middle nodes: contiguous layer ranges
-  tail node: final layers + norm + lm_head
-]
-```
-
-Route selection inputs:
-
-- model id/version/quantization
-- layer coverage
-- node hardware
-- measured prefill throughput
-- measured decode throughput
-- queue depth
-- latency to neighboring nodes
-- 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.
-
-## KV Cache Ownership
-
-KV/state ownership is by layer range:
-
-```text
-session_id = request scoped id
-node A owns layers 0..15 KV for session_id
-node B owns layers 16..31 KV for session_id
-node C owns layers 32..77 KV for session_id
-```
-
-The tracker does not own hot KV. It may know which nodes hold active KV for session accounting and failure handling.
-
-Cache servers may store:
-
-- prompt-prefix snapshots
-- 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.
-
-## 128K KV Budget
-
-GLM-5.2 compressed DSA/MLA-style estimate from config:
-
-```text
-layers = 78
-kv_lora_rank = 512
-qk_rope_head_dim = 64
-dtype = bf16 = 2 bytes
-context = 128K
-
-per_token ~= 78 * (512 + 64) * 2 = 89,856 bytes ~= 87.75 KiB
-128K total ~= 10.7 GiB
-per layer ~= 137 MiB
-```
-
-This is feasible when sharded:
-
-| Layer count | Approx active KV at 128K |
-|---:|---:|
-| 1 | 137 MiB |
-| 10 | 1.37 GiB |
-| 20 | 2.75 GiB |
-| 78 | 10.7 GiB |
-
-The exact runtime value depends on implementation and cache quantization, but the order of magnitude is acceptable.
-
-## Protocol Sketch
-
-### Prefill
-
-```http
-POST /v1/sessions/{session_id}/prefill
-Content-Type: application/octet-stream
-X-Meshnet-Model: zai-org/GLM-5.2
-X-Meshnet-Route-Id: ...
-X-Meshnet-Token-Range: 0-2047
-X-Meshnet-Shape: 1,2048,6144
-X-Meshnet-Dtype: bfloat16
-
-<activation bytes>
-```
-
-The receiver:
-
-- validates route/session
-- runs assigned layer range for that chunk
-- appends local KV/state
-- forwards resulting activation to next hop
-
-### Decode
-
-```http
-POST /v1/sessions/{session_id}/decode-step
-Content-Type: application/octet-stream
-X-Meshnet-Model: zai-org/GLM-5.2
-X-Meshnet-Position: 131072
-X-Meshnet-Shape: 1,1,6144
-X-Meshnet-Dtype: bfloat16
-
-<one-step activation bytes>
-```
-
-The receiver:
-
-- loads local KV/state by `session_id`
-- runs one decode step for assigned layers
-- appends one token position to local KV/state
-- forwards one-step activation
-
-## GGUF / llama.cpp Integration
-
-The target llama.cpp integration needs more than `llama-server`.
-
-Required capabilities:
-
-- load full GGUF locally for immediate single-node performance
-- 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.
-
-## Failure Model
-
-Alpha behavior:
-
-- Route node drops during prefill: fail request and retry from scratch.
-- 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:
-
-- periodic KV snapshots for long sessions
-- 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
+Compatible sessions may be continuously batched within a worker while retaining isolated positions/state. Admission bounds weights, local state/KV, scratch, fragments, and queues. Uncertain cross-route mutation is not replayed. Registration can show an uncertified lane, but existing admission keeps it unroutable until signed/versioned real-hardware evidence exists.

-# Distributed GGUF Decision Framework
-
-This framework is for grilling open decisions. It keeps decisions tied to project vocabulary and implementation gates instead of vague "distributed inference" language.
-
-## Core Vocabulary
-
-Use the existing domain terms this way:
-
-- **Shard**: contiguous transformer layer range. This is the compute, routing, cache, and reward unit.
-- **Shard Swarm**: storage/download group for artifacts needed by a shard.
-- **Inference Route**: ordered node sequence that covers all layers for one request.
-- **Route Session**: one active request bound to one inference route and stable session id.
-- **Hot KV State**: live per-shard cache held by the route node during a route session.
-- **Prefix Snapshot**: persisted route-session state used for reuse or failover, not the hot decode path.
-- **Artifact Manifest**: canonical mapping from model artifacts to semantic model parts and runtime support.
-- **Generation Telemetry**: realtime progress for a route session, including phase and tokens/sec, independent of whether token deltas are streamed.
-
-## The Five Planes
-
-### 1. Control Plane
-
-Owner: Tracker.
-
-Responsibilities:
-
-- node registry
-- coverage map
-- route selection
-- rebalance directives
-- route-session creation
-- health and telemetry
-- client-visible Generation Telemetry
-- billing/audit records
-
-Must not do:
-
-- serve hot KV during every token
-- become the only place model artifacts can be fetched
-
-### 2. Artifact Plane
-
-Owner: Shard Swarms, local node storage, optional CDN/bootstrap mirrors.
-
-Responsibilities:
-
-- GGUF/safetensors/tokenizer download
-- content-addressed verification
-- local artifact inventory
-- artifact-to-layer mapping
-- cache eviction
-
-Must not do:
-
-- define execution order by file split alone
-- imply that a downloaded file chunk equals a Shard
-
-### 3. Execution Plane
-
-Owner: active Inference Route.
-
-Responsibilities:
-
-- chunked prefill
-- one-step decode
-- hidden-state transfer across activation seams
-- start-layer handling for overlapping shards
-- backpressure
-
-Must not do:
-
-- resend full context activations during decode
-- require cross-node tensor parallel all-reduce for public v1
-
-### 4. Session State Plane
-
-Owner: route nodes for hot KV; cache servers only for snapshots.
-
-Responsibilities:
-
-- per-shard local KV ownership
-- cache allocation and eviction
-- cache ABI compatibility
-- session close/release
-- optional prefix snapshots
-
-Must not do:
-
-- centralize hot KV in a remote service
-- let a replacement node continue from incompatible state
-
-### 5. Economics And Trust Plane
-
-Owner: tracker plus settlement/validation components.
-
-Responsibilities:
-
-- distinguish storage/seeding work from inference work
-- account for prefill and decode separately
-- record route participation
-- sample validation events
-- slash proven fraud
-
-Must not do:
-
-- pay a node for merely holding files as if it generated tokens
-- hide public-swarm privacy limits from clients
-
-## Hard Invariants
-
-These are the framework rules unless we deliberately write a new ADR:
-
-1. Public-network Shards are contiguous layer ranges.
-2. Hot KV State is local to the node serving that Shard in that Route Session.
-3. Artifact distribution and route execution are separate systems.
-4. Decode seam payload must be `O(hidden_size)`.
-5. Prefill may be `O(sequence_length * hidden_size)`, but only in bounded chunks.
-6. The tracker chooses routes; nodes do not negotiate route topology peer-to-peer.
-7. Model/backend-specific cache internals stay behind backend capability reports.
-8. PyTorch remains the correctness/reference backend while llama.cpp/GGUF becomes the performance backend.
-9. Streaming responses are preferred when feasible; Generation Telemetry is always required.
-
-## Resolved Gates
-
-### Gate 1: Public Shard Semantics
-
-Decision: public-network Shards are contiguous transformer layer ranges. Tensor-parallel or ring-style execution is allowed only inside one trusted node, one colocated pod, or a future composite node abstraction.
-
-Rationale:
-
-- Layer ranges match the existing `Shard`, `Coverage Map`, `Inference Route`, billing, and fraud vocabulary.
-- Public volunteer nodes should not require cross-node all-reduce or tight per-layer synchronization in v1.
-- Existing projects such as prima.cpp and Distributed Llama can still inform local-cluster/backend execution without becoming the public routing primitive.
-
-Consequences:
-
-- Artifact Manifests must map files/tensors to semantic layer ranges.
-- Route selection remains ordered layer coverage.
-- Rewards can be attributed to layer-range work.
-- Hot KV State is naturally owned by the node serving that layer range for the Route Session.
-
-### Gate 2: Hot KV Strategy
-
-Decision: v1 rejects centralized hot KV. Hot KV State is local to the node serving the relevant Shard in the active Route Session. Cache servers may store Prefix Snapshots for reuse, retry, or failover, but they are not in the per-token decode path.
-
-Rationale:
-
-- Decode is the tight loop; adding remote cache I/O there makes latency and bandwidth worse at the worst point.
-- Local KV naturally follows layer-range Shard ownership.
-- Centralized hot KV increases privacy exposure and creates consistency problems.
-- Prefix Snapshots preserve the useful part of central storage without making it mandatory for every generated token.
-
-Consequences:
-
-- Route Session must be sticky.
-- Failover is limited in alpha unless a compatible Prefix Snapshot exists.
-- Cache servers are optimization infrastructure, not required runtime infrastructure.
-- Route repair requires compatible model revision, layer range, backend cache ABI, and snapshot position.
-
-### Gate 3: First Runtime Proof
-
-Decision: prove distributed Route Session and Hot KV State semantics in the existing PyTorch route before modifying llama.cpp/GGUF.
-
-Rationale:
-
-- PyTorch exposes model internals and cache objects more directly, so it is the fastest way to validate the distributed protocol.
-- The current distributed PyTorch route already has the right high-level shape but disables cache and recomputes full prompts.
-- Fixing that path gives us a reference implementation for correctness tests, telemetry, session lifecycle, and wire protocol behavior.
-- llama.cpp/GGUF should receive a clear target ABI rather than becoming both the protocol experiment and the performance backend at once.
-
-Consequences:
-
-- Issue 02 precedes issue 05.
-- llama.cpp collaboration has a concrete target ABI.
-- The PyTorch route remains the architecture-coverage/reference backend even after GGUF becomes the preferred performance path.
-- The first success metric is eliminating full-prompt recompute in distributed decode.
-
-### Gate 3A: Client Feedback During Latency
-
-Decision: streaming responses are preferred when feasible, and realtime Generation Telemetry is required regardless of streaming support.
-
-Rationale:
-
-- The product optimizes for access to large capable models, so some latency is acceptable.
-- Users still need confidence that the route is alive and roughly how fast it is generating.
-- Streaming token deltas give the best user experience when the backend exposes them cleanly.
-- Tokens/sec remains useful during prefill, queueing, and any backend that cannot stream token deltas.
-
-Consequences:
-
-- The gateway should stream token deltas through an OpenAI-compatible response when possible.
-- The gateway must expose progress through SSE, WebSocket, or polling.
-- The final answer can be delivered after completion only as a fallback.
-- Telemetry must include route phase, generated token count, and rolling tokens/sec.
-- Non-streaming clients still need realtime telemetry.
-
-### Gate 4: llama.cpp Collaboration Shape
-
-Decision: target upstreamable `libllama`/ggml hooks instead of planning around a permanent fork.
-
-Rationale:
-
-- llama.cpp changes quickly across model support, quantization, kernels, and hardware backends.
-- A permanent fork would become expensive to maintain and would lag upstream improvements.
-- A short-lived prototype branch is acceptable if it proves the API and makes upstream collaboration concrete.
-- Keeping tracker/routing logic outside llama.cpp makes the upstream ask smaller and cleaner.
-
-Consequences:
-
-- Need a minimal reproducible localhost demo before asking upstream to carry the design.
-- Need to separate "what llama.cpp should expose" from "what our tracker does".
-- Desired upstream surface is layer-range execution, hidden-state boundary I/O, partial loading/introspection, and per-session KV ownership.
-- If upstream rejects the shape, we revisit whether to carry a narrow adapter fork or keep GGUF distributed execution as experimental.
-
-### Gate 5: First Model Target
-
-Decision: use a two-tier model target. Use a small, boring, llama.cpp-supported GGUF model for the first protocol smoke test. Use `deepseek-ai/DeepSeek-V4-Flash` as the first serious large-model target. Keep GLM-5.2 and Ornith as later support audits.
-
-Rationale:
-
-- The first protocol proof should isolate route/session/KV bugs from model-architecture bugs.
-- DeepSeek-V4-Flash is a strong first serious target because it is much smaller than 1.6T-class models while still being large enough to validate the product thesis.
-- DeepSeek-V4-Flash still has architecture-specific risks, so it should not be the first smoke test.
-- GLM-5.2 and Ornith remain valuable targets, but they add DSA/MLA/hybrid attention uncertainty.
-
-Consequences:
-
-- 128K cache accounting can be modeled now.
-- The first "real" target-model audit is DeepSeek-V4-Flash support in PyTorch, vLLM/SGLang, and any available GGUF/llama.cpp quantization path.
-- Production support waits for backend capability reports and exact cache ABI support.
-
-### Gate 6: Failure Semantics
-
-Decision: alpha fails Route Sessions on route-node loss instead of attempting automatic route repair.
-
-Rationale:
-
-- Route repair requires compatible Prefix Snapshots, cache ABI checks, replacement-node selection, billing correction, and client stream/error recovery.
-- Local Hot KV State means a replacement node cannot continue unless it has compatible state at the same position.
-- Fail-fast keeps the first implementation correct while the session/KV protocol is still being proven.
-
-Consequences:
-
-- Better observability and explicit errors are required.
-- Snapshotting becomes a later feature, not a blocker for first inference.
-- Generation Telemetry must report the last known phase and failure reason.
-- Client or gateway retry starts a new Route Session from scratch.
-
-### Gate 7: Transport
-
-Decision: keep binary HTTP for v1 activation transfer instead of jumping immediately to QUIC, WebRTC, or a custom transport.
-
-Rationale:
-
-- ADR-0008 already defines binary activation bodies with HTTP headers.
-- HTTP keeps the first implementation debuggable with the existing server stack and tooling.
-- The core risk is route/session/KV correctness, not transport optimization.
-- QUIC/WebRTC can be introduced later behind the same activation protocol once semantics are proven.
-
-Consequences:
-
-- Focus benchmark work on payload shape, chunking, and cache behavior first.
-- QUIC/WebRTC can be introduced as an optimization behind the same activation protocol.
-- v1 implementation can reuse the current HTTP routing, relay, and observability infrastructure.
-- Transport abstraction should be kept narrow enough that HTTP can be replaced later without changing backend cache semantics.
-
-## Grilling Progress
-
-Gates 1, 2, 3, 3A, 4, 5, 6, and 7 are resolved. The remaining work is to convert the resolved framework into implementation-ready issue briefs and prototype milestones.
+# Distributed GGUF Runtime decision framework
+
+> **Specification status:** planning artifacts only. No distributed GGUF runtime is implemented. DGR-017 cleanup is complete; no runtime implementation story has completion credit. `prd.json` is authoritative.
+
+## Decision order
+
+1. DGR-019 locks comparable lanes and thresholds before results.
+2. DGR-020 runs safetensors and whole-model llama.cpp only, then returns `go`, `optimize baseline`, or `stop`.
+3. Dense and V4 work must prove parity, independent per-stage execution, local-state isolation, bounded failure, and measured resources.
+4. DGR-054 returns `alpha`, `optimize measured bottleneck`, or `stop`; MTP is explicitly off.
+5. Post-alpha optimizations must be selected from profiles, not assumptions.
+6. DGR-070 returns `beta`, `targeted optimization`, or `stop/rollback`, and requires MTP and the exact certified hardware/recipe matrix.
+
+## Interpretation rules
+
+- Quant/model-fit gains are separate from runtime/kernel/transport gains.
+- Fixture, real-model, real-hardware, and release evidence are never interchangeable.
+- 2–4 and 10+ stages are certification scenarios only.
+- Existing routing policy is certified, not redesigned.
+- Build success is not hardware certification; dark lanes remain unroutable.
+- Route loss uses cache miss and re-prefill/restart, never WAN cache migration.
+
+## Locked scope
+
+- Existing Meshnet Tracker routing, load balancing, billing, telemetry, relay, and provider semantics are backend-agnostic and are **not redesigned**. GGUF contributes exact compatibility, range/capacity, queue/load, seam-cost, health/reliability, and certification inputs only.
+- The data plane is a standalone project-owned C++ Shard worker with gRPC/Protobuf and a project-owned `ShardEngine` boundary.
+- llama.cpp is fetched at one exact commit into an ignored workspace from an in-repo manifest, then a numbered minimal patch stack is applied. There is no submodule, vendored tree, or permanent-fork dependency.
+- llama.cpp owns DeepSeek V4 graphs, mHC, MoE, attention, hash routing, and kernels. Meshnet adds only range-ownership hooks, typed boundary/local-state adapters, worker integration, and parity/certification.
+- Quantization and placement are dynamic recipe inputs. The 2–4 and 10+ stage layouts are certification scenarios, never product constants.
+- Per-shard Hot KV and V4 CSA/HCA/SWA/indexer/compressor state remain local and keyed by route session/epoch. The WAN seam carries the typed mHC 4×4096 residual boundary, positions, token-ID sideband where required, and schema/cache expectations—not per-layer caches.
+- Route changes use cache miss plus re-prefill/restart. There is no WAN KV or V4 auxiliary-cache migration.
+- CPU/CUDA/ROCm/Vulkan/Metal compile lanes are planned; only exact real-hardware-certified backend/model/recipe lanes may be advertised.
+- Alpha requires correctness and the pre-locked useful-speed gate. MTP is reserved and off for alpha; its ownership contract, implementation, and benchmark are required before beta.
+
+## Target identities
+
+- DeepSeek V4 official target SHA: `60d8d70770c6776ff598c94bb586a859a38244f1`.
+- llama.cpp V4 support lineage began at PR 24162 / merge `8c146a8366304c871efc26057cc90370ccf58dad`; DGR-027 later pins one exact validated current commit.
+- V4 scope: 43 main layers plus MTP; mHC 4×4096 boundary; 256 routed + 1 shared experts with six routed active; token IDs required for the first three hash-routed layers.
+- Exact split-GGUF artifacts are provisioned to mounted-drive storage with a complete hashed manifest and resumable verification; no model artifact may be placed under `/home`.

+- Workload: three fixed short/medium/long prompts, greedy sampling, 32 output
+  tokens, three repeats, two warmups, concurrency 1 and 4, 16 CPU threads
+- Evidence class: `local-real`
+
+All artifacts are beneath `/run/media/popov/DATA/llm/`; no model artifact was
+created under `/home`.
+
+## Recipes and exact artifacts
+
+| Recipe | Artifact | SHA-256 |
+|---|---|---|
+| Transformers BF16 reference | complete mounted Hugging Face snapshot | `e596e9d6205fdc9177569cccd7f8b471b058f66e3630c8e4326d5aad52bd18b6` |

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

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

+# DGR-001 quality-parity evidence summary
+
+This summary is generated by `summarize-quality-parity.py` from signed reports.
+It contains no independent logit measurements or self-asserted verification flag.
+
+| Source | Device | Quality oracle | BF16 GGUF candidate | Exact | Similarity | Status |
+|---|---|---|---|---:|---:|---|
+| CPU v1 (`e4eedadf-22f6-4907-8990-985456961099`) | CPU | Transformers BF16 | llama.cpp BF16 | 0.3333 | 0.9471 | immutable `stop` |
+| ROCm diagnostic (`31bf44e7-ccd4-4277-84ac-c775dee65411`) | ROCm0 / Radeon 8060S | Transformers float32 | llama.cpp BF16 | 1.0000 | 1.0000 | diagnostic only |
+
+## Interpretation
+
+The CPU and ROCm rows use different plans, devices, kernels, and quality oracles.
+The CPU BF16 divergence remains unexplained and v1 remains `stop`. The signed
+ROCm report establishes the narrower fact that the same BF16 GGUF artifact
+matched the float32 oracle for all three GPU sequences with zero failures.
+Its signed backend detail records `ROCm0: Radeon 8060S Graphics` and measured
+`25/25` layer offload.
+
+No conversion corruption was observed in that three-sequence ROCm sample. This
+does not prove global conversion correctness and does not retroactively change
+or explain the CPU result. A future v2 should predeclare a float32 quality oracle
+separately from its BF16 performance reference and use a larger corpus.

+
+The CPU and ROCm rows use different plans, devices, kernels, and quality oracles.
+The CPU BF16 divergence remains unexplained and v1 remains `stop`. The signed
+ROCm report establishes the narrower fact that the same BF16 GGUF artifact
+matched the float32 oracle for all three GPU sequences with zero failures.
+Its signed backend detail records `ROCm0: Radeon 8060S Graphics` and measured

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

+| `packages/node/meshnet_node/native_protocol/__init__.py` | Public Python surface |
+| `packages/node/meshnet_node/native_protocol/codec.py` | Bundle encode/decode, fragmentation, CRC32C, chunking, FC negotiation |
+| `packages/node/meshnet_node/native_protocol/conformance.py` | Canonical vectors shared by both languages |
+| `packages/node/meshnet_node/native_protocol/generated/` | Generated Python stubs (committed) |
+| `scripts/generate_native_protocol.py` | Python generation, with `--check` |

+| `scripts/bootstrap_native_toolchain.sh` | Builds protobuf C++ from source |
+| `tests/test_native_shard_protocol.py` | 45 Python tests |
+
+Modified:
+
+- `packages/node/pyproject.toml` — added runtime floors `grpcio>=1.82.1` and
+  `protobuf>=7.35.0`, matching the committed generated-code requirements; new
+  `proto` extra pinning `grpcio-tools==1.82.1`.
+- `packages/node/meshnet_node/activation_compression.py` — optional bounded zstd
+  output for untrusted protocol frames; existing callers remain compatible.
+- `packages/node/meshnet_node/native_protocol/__init__.py` — exports negotiated
+  bound constants and whole-session-message validation.
+
+The canonical PRD marks only DGR-002 passed. `git status` before this story was clean.

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

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

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

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

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

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

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

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

+# DGR-006 — architecture-defined boundary input/output
+
+Status: complete deterministic/offline contract and dense-fixture evidence.
+
+## Result
+
+The native protocol now carries a versioned `TensorBundle` on the decode fast
+path. It includes explicit architecture and boundary-point metadata. Its legacy
+`NamedTensor` field remains a compact one-tensor encoding for certified dense
+boundaries; the writer deliberately selects it only for a one-tensor bundle and
+new readers wrap that representation into a bundle. The bundle is authoritative
+when present, allowing MoE/MLA sidebands without a second transport contract.
+
+`architecture_boundary.py` is the fail-closed adapter boundary. Dense head
+Shards accept token IDs and own embedding. Middle/tail Shards accept only a
+validated bundle. Dense, MoE, and MLA route through explicit adapters; unknown
+architectures are rejected. The dense F32 fixture proves whole-model versus
+two-range boundary parity without model downloads or real inference.
+
+Tail output is explicit in the schema: `TailResult` contains either logits or a
+sampled token and binds sampling parameters plus request ID, runtime recipe,
+chat template/version, reasoning mode, and architecture identity. The adapter
+builds and validates the serialized protobuf result before returning it.

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

+# DGR-017 evidence — superseded backlog cleanup
+
+**Completed:** 2026-07-16
+**Branch:** `ralph/distributed-gguf-runtime`
+**Planning checkpoint before cleanup:** `81b1fa6`
+**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
+
+## Outcome
+
+The old DGR-001…016 completion claims and active artifacts were reconciled against the live branch. No old pass state transferred to the new implementation roadmap.
+
+The active `packages/` and `tests/` trees were restored exactly to `origin/master`. The branch therefore no longer exposes a nominal GGUF startup path backed by unimplemented transport methods, a protobuf-only native scaffold, or isolated synthetic scheduler/cache/failure modules as if they were a working distributed GGUF runtime.
+
+## Classification and disposition
+
+### Retained
+
+- Accepted ADRs and repository research, including `docs/research/colibri-implementation-audit.md`.
+- The authoritative 55-story roadmap `DGR-017…071` and its generated issue specifications.
+- The real public-relay smoke benchmark, moved with provenance to `legacy-public-relay-smoke-benchmark.json`.
+- Git history containing the complete superseded implementation/reference work.
+
+### Removed from the active tree
+
+- Legacy issue specifications DGR-001…016 and their stale/blocked/synthetic evidence directories.
+- The nonfunctional `gguf_backend` startup path whose gRPC execution methods raised not-implemented errors.
+- Synthetic/reference-only boundary, Hot KV, scheduler, failure, recipe, ownership, and native-protocol modules that were not a real llama.cpp Shard runtime.
+- The protobuf round-trip-only native scaffold, placeholder llama.cpp patch, generated bindings/build workspace, and associated tests.
+- Tracker/admission/source modifications coupled to that superseded scaffold.
+
+### Confirmed absent and still required
+
+- Real standalone C++ gRPC Shard worker.
+- Exact pinned llama.cpp manifest and verified patch stack.
+- Range-aware GGUF tensor ownership and real ranged execution.
+- Real Shard-local llama.cpp KV/V4 auxiliary state.
+- DeepSeek V4 boundary adapter and ranged parity.
+- Real multi-machine DeepSeek V4 alpha or beta acceptance.
+
+These remain `passes: false` in DGR-018…071.
+
+## Before-cleanup baseline
+
+Command:
+
+```bash
+.venv-rocm/bin/python -m pytest -q \
+  tests/test_performance_contract.py tests/test_native_shard_protocol.py \
+  tests/test_gguf_ownership.py tests/test_boundary_adapter.py \
+  tests/test_hot_kv_state.py tests/test_gguf_backend.py \
+  tests/test_batch_scheduler.py tests/test_failure_semantics.py \
+  tests/test_llama_worker_build.py tests/test_node_admission.py \
+  tests/test_node_capability.py tests/test_tracker_capability_admission.py
+```
+
+Result:
+
+```text
+216 passed, 2 skipped, 1 failed, 1 warning
+```
+
+The failure was a synthetic capability-test helper `KeyError: 'compatibility_fingerprint'`. The warning was a pre-existing heartbeat-thread `SystemExit` warning.
+
+## Cleanup verification
+
+### Source equality
+
+Command:
+
+```bash
+git diff --quiet origin/master -- packages tests
+```
+
+Result:
+
+```text
+packages_tests_match_origin_master=yes
+```
+
+The staged cleanup removes approximately 15.3k obsolete source/test/evidence lines from the active branch.
+
+### Cleanup-relevant regression suite
+
+Command:
+
+```bash
+.venv-rocm/bin/python -m pytest -q \
+  tests/test_node_admission.py tests/test_node_capability.py \
+  tests/test_tracker_capability_admission.py \
+  tests/test_kv_cache_distributed.py tests/test_real_distributed_inference.py
+```
+
+Result:
+
+```text
+119 passed, 2 skipped, 1 warning in 15.90s
+```
+
+The warning is the same pre-existing heartbeat-thread `SystemExit` warning.
+
+### Known `origin/master` limitations
+
+The wider routing run produced `210 passed, 2 skipped, 4 failed, 1 warning`. Each failure reproduced individually while `packages/` and `tests/` matched `origin/master` exactly:
+
+- `test_tracker_models_endpoint_lists_registered_hf_repo_and_short_name_alias`
+- `test_torch_node_applies_tracker_load_shard_directive`
+- `test_shard_heal_cycle_surviving_node_covers_dead_peers_gap`
+- `test_a_node_with_an_unusable_precision_covers_no_layers`
+
+They are recorded as pre-existing baseline defects and were not repaired or hidden by this cleanup story.
+
+## Dependency handoff
+
+DGR-018 and later stories must start from the cleaned upstream-equivalent runtime tree. Reuse concepts from superseded commits only by explicitly porting the smallest verified slice under the new story’s contracts, tests, and evidence gates. Git history is provenance, not completion evidence.

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

+never contacts the network):

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

+# DGR-018 evidence — canonical Ralph and Gitea metadata schema
+
+**Completed:** 2026-07-16
+**Branch:** `ralph/distributed-gguf-runtime`
+**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
+**Dependency:** DGR-017 (`evidence/DGR-017/README.md`) — cleaned backlog reconciled to `origin/master`; no old pass state transferred.
+
+## Objective
+
+Make `prd.json` the validated source from which Markdown (and, later, Gitea) issues
+can be generated losslessly, per
+`.scratch/distributed-gguf-runtime/issues/018-define-canonical-ralph-and-gitea-metadata-schema.md`.
+
+## Pre-existing state found (not caused by this story)
+
+Before any change in this session, `git status` showed `.scratch/distributed-gguf-runtime/prd.json`
+already modified in the working tree relative to `HEAD` (commit `369b207`), with no corresponding
+progress-log entry. Diffing against `HEAD` showed the working copy had **dropped** prd.json's
+top-level `sourceOfTruth`, `qualityGates`, `metadataSchema`, `milestones`, and `supersededStories`
+objects, while `userStories` itself was byte-identical to `HEAD`. This looked like an abandoned,
+uncommitted partial edit from a prior session, not intentional current work — those fields are
+exactly the schema/quality-gate/audit-provenance content this story depends on, and their loss
+wasn't explained by any acceptance criterion. They were restored (see "Changes" below) rather than
+silently accepted or discarded, per the instruction to investigate unexplained working-tree state
+before building on top of it.

+## Changes
+
+### `scripts/ralph_prd_schema.py` (new)
+
+Single module providing:
+
+- **Parse:** `load_prd(path)` — JSON load with clear `PrdValidationError`s for missing file /
+  invalid JSON / non-object document.
+- **Canonical schema registry:** `STORY_FIELDS` (name → required/type), `EXECUTION_MODES`,
+  `EVIDENCE_CLASSES`, `HARDWARE_FLAGS`, `UPSTREAM_FLAGS`, `TRIAGE_VALUES`. Covers every field named
+  in the acceptance criteria: stable `id`/`title`, `labels`, `milestone`, derived `type`
+  (`derive_type`), `dependsOn`, derived `blocks`, `triage`, `evidenceClass`, and
+  `hardware`/`model`/`upstream` flags.
+- **Structural validation:** `validate_schema(data)` — required fields, types, enum membership,
+  ID convention, `type:`/`priority:` label cardinality, non-empty `acceptanceCriteria`.
+- **Semantic validation:** `validate_semantics(data)` — unique IDs, unique titles, `dependsOn`
+  resolves to known stories (no self-dependency), dependency graph is acyclic (with a reported
+  cycle path on failure), `blocks` matches the dependency graph exactly (sorted set equality, not
+  superset), and `evidencePath` matches the per-story convention.
+- **Fresh vs. in-progress backlog:** `validate_fresh_backlog(data)` additionally requires every
+  story to start `passes: false` (for a backlog that hasn't started execution yet);
+  `validate_backlog(data)` is the composed check for a real, in-flight backlog where some stories
+  have legitimately completed.
+- **Self-consistency check:** `validate_metadata_schema_consistency(data)` — when prd.json declares
+  its own `metadataSchema`/`qualityGates` (as this one now does), verifies that self-documentation
+  hasn't drifted from what the validator actually enforces (enum sets, required/optional field
+  lists, presence of `qualityGates` and `generatedArtifactDisclaimer`). This is a no-op for minimal
+  fixture PRDs that don't carry that documentation.
+- **Generation (one-directional, prd.json → artifact):** `render_issue_markdown(story, data)`
+  renders the exact Markdown convention already used by
+  `.scratch/distributed-gguf-runtime/issues/*.md`, sourcing the "Shared quality gates" bullets from
+  `data["qualityGates"]` and the leading disclaimer from
+  `data["metadataSchema"]["generatedArtifactDisclaimer"]` (falling back to a module default only
+  when `data` omits them) — not from a duplicated Python string literal.
+  `to_gitea_issue_payload(story, data)` wraps the same body into a Gitea create-issue-shaped payload
+  (`title`, `body`, `labels`, `milestone`).
+- **Authority guard:** `check_generated_markdown_authority(text, disclaimer=...)` rejects generated
+  Markdown that's missing the disclaimer or that contains a conflicting authority claim (e.g. "this
+  file is authoritative"). There is deliberately no Markdown → prd.json parser, so a generated
+  artifact structurally cannot feed `passes` (or anything else) back into the authoritative source.
+- CLI: `python scripts/ralph_prd_schema.py validate <prd.json> [--fresh]` and
+  `... render <prd.json> <STORY-ID>`.
+
+### `.scratch/distributed-gguf-runtime/prd.json`
+
+- Restored the top-level `sourceOfTruth`, `qualityGates`, `milestones`, and `supersededStories`
+  objects to their `HEAD` content (see "Pre-existing state" above); `userStories` was already
+  identical to `HEAD` and is unchanged in content.
+- Extended `metadataSchema` (previously incomplete for this story's own acceptance criteria) with:
+  `requiredStoryFields` now also lists `notes` and `blocks` (present on all 55 stories); new
+  `optionalStoryFields: ["completionNotes"]`; new `hardwareValues`/`upstreamValues` enums (`model`
+  is documented as an open convention, not a closed enum, since quantization/model targets are
+  dynamic recipe inputs per `RALPH-CONTEXT.md`); new `typeDerivation` and `labelConventions`
+  (reserved prefixes, cardinality); new `generatedArtifactDisclaimer` (the exact string generated
+  artifacts must start with); extended `dependencyRules`/`authorityRule` prose to match what the
+  validator enforces.
+- Reworded `sourceOfTruth`'s stale "All stories are unimplemented ... passes=false" clause, which
+  was no longer accurate once DGR-017 completed.
+- Marked `DGR-018.passes = true` with `completionNotes` recording this story's outcome.
+
+### `.scratch/distributed-gguf-runtime/issues/018-define-canonical-ralph-and-gitea-metadata-schema.md`
+
+Regenerated via `render_issue_markdown` to reflect `passes: true` (checked acceptance criteria,
+"completed" status line, "Verified evidence" handoff line) — matching the same convention DGR-017's
+issue file already used for a completed story.
+
+### `tests/test_ralph_prd_schema.py` (new)
+
+108 deterministic, model-download-free, GPU-free tests:
+
+- **Parse** (4 tests): real backlog parses to 55 stories; missing file, invalid JSON, and
+  non-object documents raise `PrdValidationError`.
+- **Structural/semantic validation against the real backlog** (7 tests): passes `validate_schema`,
+  `validate_semantics`, and the composed `validate_backlog`; unique IDs/titles; all `dependsOn`
+  resolve; `blocks` matches the derived dependency graph for all 55 stories; no cycle; every
+  `passes: true` story carries `completionNotes` and an existing evidence README (a durable
+  invariant, not a hardcoded list of which stories have completed — that list will keep growing).
+- **Structural/semantic failure-mode fixtures** (13 tests): missing required field, bad enum, wrong
+  type, empty `acceptanceCriteria`, multiple `type:` labels, duplicate ID, duplicate title, unknown
+  dependency, self-dependency, dependency cycle, mismatched `blocks`, bad `evidencePath`.
+- **Fresh-backlog invariant** (3 tests): accepts all-`false`, rejects a premature `passes: true`,
+  and confirms `validate_backlog` (the in-progress variant) permits completed stories.
+- **prd.json-as-source-of-truth for boilerplate** (9 tests): `qualityGates`/`metadataSchema`
+  self-consistency checks (no-op without them, catches a drifted enum, catches a missing
+  `qualityGates`), `quality_gate_bullets` flattening order, `authority_disclaimer` precedence and
+  fallback, and 3 tests asserting the real backlog's declared schema matches the code, its 7
+  quality-gate bullets are intact, and its disclaimer matches the module default.
+- **`derive_type`** (4 tests): label-derived type, release-gate synthetic type for HITL gate
+  stories, `None` when absent, and confirmation that the real backlog's two release-gate stories
+  (`DGR-054`, `DGR-070`) derive `release-gate`.
+- **Markdown generation round trips** (55 parametrized + 6 tests): `render_issue_markdown` for
+  every story `DGR-017`..`DGR-071` is byte-for-byte identical to the corresponding file already in
+  `.scratch/distributed-gguf-runtime/issues/`; determinism; leading disclaimer; `Blocks (derived)`
+  rendering (`None` vs. listed); checkbox reflects `passes`; filename convention.
+- **Authority-claim rejection** (4 tests): accepts real generated text, rejects a missing
+  disclaimer, rejects an overriding claim, and confirms every committed issue file in
+  `.scratch/distributed-gguf-runtime/issues/` passes the check.
+- **Gitea payload generation** (3 tests): payload shape, body carries no information beyond what's
+  in prd.json, and every real story's payload is well-formed and authority-clean.
+
+## Commands and results
+
+```bash
+python3 -m pytest -q tests/test_ralph_prd_schema.py
+```
+```text
+108 passed in 0.16s
+```
+
+```bash
+python3 -m compileall -q packages tests
+```
+Exit code 0, no output (all files compile).
+
+```bash
+git diff --check
+```
+Exit code 0 (no whitespace errors).
+
+```bash
+python3 scripts/ralph_prd_schema.py validate .scratch/distributed-gguf-runtime/prd.json
+```
+```text
+OK: 55 stories validated.
+```
+
+```bash
+python3 scripts/ralph_prd_schema.py validate .scratch/distributed-gguf-runtime/prd.json --fresh
+```
+```text
+ERROR: DGR-017: fresh backlog requires passes=false, got True
+ERROR: DGR-018: fresh backlog requires passes=false, got True
+2 validation error(s).
+```
+Expected: `--fresh` is the invariant for a backlog that hasn't started execution; this backlog has
+legitimately completed two stories, so it correctly fails that stricter check while passing the
+plain (in-progress) `validate` command above.
+
+### Baseline: full repository suite (ad hoc `python3`, not a project venv)
+
+```bash
+python3 -m pytest -q
+```
+```text
+20 failed, 776 passed, 13 skipped, 2 warnings in 244.17s (0:04:04)
+```
+None of the failures touch `scripts/ralph_prd_schema.py` or `tests/test_ralph_prd_schema.py`
+(neither file existed before this story; this story adds no changes to `packages/`). Four of the
+20 failures reproduce exactly the pre-existing baseline defects DGR-017's evidence already recorded
+(`test_tracker_models_endpoint_lists_registered_hf_repo_and_short_name_alias`,
+`test_torch_node_applies_tracker_load_shard_directive`,
+`test_shard_heal_cycle_surviving_node_covers_dead_peers_gap`,
+`test_a_node_with_an_unusable_precision_covers_no_layers`). The remaining 16 (activation
+compression, dynamic routing, gossip/relay, manual route benchmark, openai gateway, TOPLoC
+calibration dispatch, tracker control plane) include a `ModuleNotFoundError: langchain` failure,
+indicating this ad hoc `python3` lacks the project's `dev` extras (`langchain-openai`, etc.) rather
+than a real regression; this environment has no project virtualenv (e.g. no `.venv-rocm`) to run
+against instead. Not investigated further as out of scope for this story.
+
+## Limitations
+
+- No real Gitea instance or API integration exists; `to_gitea_issue_payload` defines the payload
+  shape (title/body/labels/milestone) only. Creating issues against a live Gitea server is future
+  work, not claimed here.
+- `model` is intentionally validated as an open string, not a closed enum, per
+  `RALPH-CONTEXT.md`'s "Quantization and placement are dynamic recipe inputs" constraint; the schema
+  documents (`metadataSchema.modelConvention`) but does not restrict its value set.
+- Validation and generation were exercised only against this feature's `prd.json`
+  (`.scratch/distributed-gguf-runtime/prd.json`); `docs/prd.json` and other `.scratch/*/prd.json`
+  files in this repo use a materially different (simpler) shape and are out of scope.
+
+## Dependency handoff
+
+DGR-021 and DGR-025 (this story's derived `blocks`) may treat `prd.json`'s `metadataSchema`,
+`qualityGates`, and this validator/generator as stable. Any future field addition to a story shape
+must extend `STORY_FIELDS` in `scripts/ralph_prd_schema.py` and the corresponding
+`metadataSchema.requiredStoryFields`/`optionalStoryFields` in `prd.json` together —
+`validate_metadata_schema_consistency` fails closed if they drift apart.
