+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).
+
+## What to build
+

+- [ ] Criterion 1
+- [ ] Criterion 2
+
+## Blocked by
+
+- A reference to each blocking ticket, or "None — can start immediately".
+
+</issue-template>
+
+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.

Wayfinding is about finding that way, not charging at the destination. This skill charts the way as a **shared map** on the repo's issue tracker, then works its **decision tickets** — questions whose resolution is a decision, not slices of a build to execute — one at a time until the route is clear.
+
+The destination varies per effort, and naming it is the first act of charting — it shapes every ticket.

The map is domain-agnostic — engineering work, course content, whatever fits the shape.

+## Plan, don't do
+
+Wayfinder is **planning** by default: each ticket resolves a decision, and the map is done when the way is clear — nothing left to decide before someone goes and does the thing. The pull to just do the work is usually the signal you've reached the edge of the map and it's time to hand off. An effort can override this in its **Notes** — carrying execution into the map itself — but absent that, produce decisions, not deliverables.

+
+## 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.

+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.

Native data plane uses versioned Protobuf over long-lived gRPC/HTTP2 seam streams, with existing relay carrying the same opaque frames when needed. llama.cpp/GGML remains the substrate behind a project-owned standalone worker and small pinned fork; vLLM is an optional complete managed provider and concept donor, not a fork. Nakshatra, `prima.cpp`, `llama-gguf`, LiGGUF and historical GPUStack are source/test donors only.

 **Launch-readiness grilling (2026-07-06):** Locked launch plan — devnet dev/test run now, then **real mainnet SOL/USDT** (not devnet, not a new public token) for the first cohort: friends (API clients) + hired VPS/VPC hosts (our own test infra, not third-party volunteers — stake-free, risk-free if something breaks, not a long-term topology). Pricing: clients are the only party spending real money; nodes only accumulate off-chain credit and get paid in batches (30min dev / 24h later) — a failed distribution leaves funds parked, not lost, so mainnet-vs-devnet mixups are lower-risk than initially assumed. TAI token: do NOT issue/list now — ADR-0002 already locks listing behind $50k volume + 25 nodes/15 wallets plus an unresolved securities-review gate; only a dormant mainnet mint (cheap, ~few $ SOL) for name/branding reservation is in scope, bundled with treasury-key work, not before it. Treasury custody: bare keypair file (current runbook 02) is not acceptable for real funds — plan is **free native SPL multisig** (`spl-token create-multisig`, no protocol fee unlike Squads' 0.5 SOL), 2-of-3 signers, at least one cold/offline, others one-per-hired-VPS-provider to avoid correlated compromise (not yet built — ops task, no issue filed). Stake/slash asymmetry (registry/slash is a local Python adapter per ADR-0007, not on-chain) accepted for now since hired hosts are our own infra and friends aren't node operators — revisit before opening to real third-party node operators. A mainnet-vs-devnet boot guardrail was proposed and explicitly declined by the owner given the safe-by-default money flow above.
 
-**Two new issues from this session, both `ready-for-agent`:**
-- **21 — Honest-noise calibration corpus** (`.scratch/alpha-hardening/issues/21-honest-noise-calibration-corpus.md`) rescoped from "prod gate" to a **hard alpha-release blocker**. Confirmed by code read: `verify_activation_proofs()` (`packages/validator/meshnet_validator/audit.py:94-127`) returns bool only, no raw divergence value; fleet-dispatch exists but wrong shape (`server.py:2998-3104`, pinned routes + latency, not full-fleet + TOPLOC divergence); storage wrong shape (`registry_events` has no divergence/hardware columns). Three-part build: (1) surface raw TOPLOC distance from audit.py, (2) extend dispatch to hit every registered node with fixed prompt/seed, (3) new SQLite table keyed by node+GPU+dtype. Small-fleet exception granted (N = actual hired-VPS fleet size). Hired VPS hosts stay stake-free until this closes.
-- **23 — Dynamic HF-benchmarked pricing** (`.scratch/alpha-hardening/issues/23-dynamic-hf-pricing.md`), high priority but not a release blocker. Pricing today is 100% static (`DEFAULT_PRICE_PER_1K_TOKENS = 0.02`, `billing.py:21`; `model_presets.json` has no per-model price). Target: 80% of cheapest comparable provider on `https://huggingface.co/inference/models` (per-provider-per-model marketplace, `?search=` query param works, no confirmed JSON API — plain scrape attempted first, escalate to headless browser only if the table isn't in raw HTML). Human-verified `hf_aliases` + `hf_verified_match_note` (params/quantization) per model, not auto-discovered matching. Reuses the `_settlement_loop` daemon-thread pattern for a daily refresh; falls back silently to the static default on any failure.
+**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)])
+

+```
+
+#### 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':[]}

+### 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

+
+# 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

+# 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).')

+"
+```
+
+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

+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

+
+If graphify saved you time, consider supporting it: https://github.com/sponsors/safishamsi
+
+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
+$(cat graphify-out/.graphify_python) -c "
+import sys
+from graphify.ingest import ingest
+from pathlib import Path
+
+try:
+    out = ingest('URL', Path('./raw'), author='AUTHOR', contributor='CONTRIBUTOR')
+    print(f'Saved to {out}')
+except ValueError as e:
+    print(f'error: {e}', file=sys.stderr)
+    sys.exit(1)
+except RuntimeError as e:
+    print(f'error: {e}', file=sys.stderr)
+    sys.exit(1)
+"
+```
+
+Replace `URL` with the actual URL, `AUTHOR` with the user's name if provided, `CONTRIBUTOR` likewise. If the command exits with an error, tell the user what went wrong - do not silently continue. After a successful save, automatically run the `--update` pipeline on `./raw` to merge the new file into the existing graph.
+
+Supported URL types (auto-detected):
+- YouTube / any video URL → audio downloaded via yt-dlp, transcribed to `.txt` on next run (requires `pip install 'graphifyy[video]'`)
+- Twitter/X → fetched via oEmbed, saved as `.md` with tweet text and author
+- arXiv → abstract + metadata saved as `.md`
+- PDF → downloaded as `.pdf`
+- Images (.png/.jpg/.webp) → downloaded, Claude vision extracts on next run
+- Any webpage → converted to markdown via html2text
+
+---
+
+## For --watch
+
+Start a background watcher that monitors a folder and auto-updates the graph when files change.
+
+```bash
+$(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.

+
+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_files': r.get('new_total', 0),
+    '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 "

+[08:48:30] [INFO] [agent] DGR-019 is complete.
+[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.

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.
+- [ ] `pytest` targeted tests and `python -m compileall packages tests` pass.
+
+## Likely files
+
+- Modify: `packages/node/meshnet_node/startup.py`, `packages/node/meshnet_node/testing.py`, `packages/node/meshnet_node/cli.py`
+- Modify/add: `tests/test_node_startup.py`, `tests/test_node_admission.py`, `tests/test_mining_cli.py`
+
+## Non-goals
+
+No new backend type, no Tracker placement algorithm change, and no native-worker process supervision.

+# 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`
+
+## Non-goals
+
+No redesign of the Tracker architecture, no public endpoint removal, and no change to backend-neutral provider semantics.

-Last updated: 2026-07-13

+## Mandatory startup for every fresh story
 
-Before changing code, every Ralph agent must:
+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.
+4. Read `docs/adr/0024-distributed-gguf-runtime.md`, root `CONTEXT.md`, `.claude/memory/MEMORY.md`, and relevant live source/tests.
+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.
 
-1. Read this file completely.
-2. Read the selected issue under `.scratch/distributed-gguf-runtime/issues/`.
-3. Read `.scratch/distributed-gguf-runtime/GLM-5.2-MAX-ALPHA-ROADMAP.md`, `.scratch/distributed-gguf-runtime/ADR-0020-distributed-gguf-runtime.md`, and the relevant part of `architecture.md`.
-4. Read `.claude/memory/MEMORY.md` and root `CONTEXT.md` for current project vocabulary and constraints.
-5. Inspect the current implementation and tests; do not assume historical scratch text describes live code.
-6. Read the evidence/handoff directories for every declared dependency.
-7. Inspect `git status` and preserve all pre-existing working-tree changes.
+## Locked scope
 
-A fresh Ralph iteration has no conversational memory. These files are the context contract.
+- 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.
 
-## Story sizing and interruption rule
+## Target identities
 
-Each story is intended to fit one focused Ralph context. Before implementation, estimate whether every acceptance criterion can be completed and verified in the current iteration.
+- 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`.
 
-If the story is too large, an external dependency is unavailable, or the context/provider limit prevents completion:
+## Control/data-plane contract
 
-- Do not weaken criteria.
-- Do not mark the issue done or set `passes: true`.
-- Avoid leaving an unverified cross-cutting partial implementation when a smaller safe spike is possible.
-- Write `evidence/<TASK-ID>/DECOMPOSITION.md` or `BLOCKED.md` with the exact blocker, current verified state, proposed child stories, dependency graph and rollback/continuation instructions.
-- Stop for supervised review.
+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.
 
-If interrupted after code changes, record every changed file, command result and unresolved invariant so the next fresh loop can verify rather than guess.
+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`.
 
-## Product objective
+## Gitea issue synchronization
 
-Build performant, concurrent distributed inference that combines consumer machines to serve top open models that exceed one node's RAM/VRAM.
+Gitea is a projection of `prd.json`, never a competing source of truth. Before and after every supervised Ralph run, invoke:
 
-The alpha target is the exact pinned GLM-5.2 `UD-IQ1_S` artifact served with `reasoning_effort=max` across physical consumer machines. Dense Llama is a structural fixture. Synthetic workers, dense-attention compatibility fallback, a smaller model, or a single host cannot satisfy target alpha. The immutable target contract and resource envelope are in `GLM-5.2-MAX-ALPHA-ROADMAP.md`.
-
-A distributed demo is not success. The product must provide:
-
-- Useful measured prefill and decode speed.
-- Multiple concurrent Route Sessions.
-- No KV/token cross-talk.
-- Bounded memory, queues, cancellation and failures.
-- Real execution on every participating node.
-- A model-fit or performance advantage over the current Transformers/safetensors route.

-        |
-Project-owned standalone C++ Shard worker
-        |

+```bash

 ```
 
-Meshnet remains the only control plane and owns:
+For a complete Ralph invocation with automatic state reconciliation, use:
 
-- Tracker registration, Coverage Map, route selection and route epochs.
-- Route Sessions and Activation Seams.
-- Direct/relay routing.
-- Capability admission.
-- Cancellation, Generation Telemetry and backpressure.
-- Billing, validation and per-node work attribution.
-
-Do not introduce another scheduler/control plane from vLLM, Nakshatra, prima.cpp, llama-gguf, GPUStack or another project.
-
-## Runtime decisions that are not open
-
-1. Public-network Shards are contiguous transformer layer ranges.
-2. llama.cpp/GGML is the native GGUF execution substrate.
-3. The project owns a small standalone worker and a narrow pinned llama.cpp patch stack.
-4. The native Shard protocol is Protocol Buffers over gRPC/HTTP2.
-5. One long-lived bidirectional stream serves one Route Session Activation Seam.
-6. The public activation boundary is a versioned named-tensor bundle.
-7. Hot KV State remains local to the node serving the Shard.
-8. `(Route Session ID, route epoch)` maps to an isolated llama sequence or bounded context.
-9. Concurrency uses continuous batching of compatible active sessions inside each node.
-10. Transformers/safetensors remains the correctness and performance baseline.
-11. vLLM may be an optional complete managed provider and concept donor; it is not forked into public Shards.
-12. Tensor/expert collectives are deferred to a trusted composite provider, not public WAN routes.
-13. Unsupported architectures/backends remain registered-but-dark until real certification passes.
-14. Alpha failure retries from token zero; unverified KV is never migrated silently.
-15. Model artifacts must remain on mounted-drive storage and never under `/home`.
-16. Unified system RAM and integrated-GPU memory are one physical pool and must never be double-counted for admission.
-17. Alpha requires native GLM-5.2 MoE, DSA, and IndexShare semantics; MTP/speculative decoding and 1M-context certification are post-alpha.
-18. DGR-006 amends the decode fast path to carry a versioned `TensorBundle` and defines a typed tail logits/token result; the current single-`NamedTensor` fast path is insufficient for GLM sidebands.
-19. Alpha reserves at least `max(20% of physical usable memory, 8 GiB)` per node outside weight-plus-Q8-KV placement and uses a same-switch wired 2.5 GbE minimum route.
-
-Changing one of these requires an explicit ADR update and human review, not an incidental story implementation.
-
-## Performance discipline
-
-GGUF performance is a hypothesis. Never write “GGUF is faster” without measurements.
-
-DGR-001 locks controlled benchmark lanes and thresholds. DGR-014 enforces the final distributed comparison.
-
-Always distinguish:
-
-- Weight quantization from activation/compute/KV dtype.
-- Runtime/kernel gains from quantization/model-fit gains.
-- Single-request latency from aggregate concurrency throughput.
-- Synthetic unit coverage from real distributed acceptance.
-
-Required metrics where applicable:
-
-```text
-TTFT
-prefill tokens/sec
-decode tokens/sec
-aggregate throughput
-p50/p95 latency
-seam bytes and latency
-queue and batch occupancy
-RSS and VRAM
-KV pressure
-output-quality drift
-failures and cleanup
+```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
 ```
 
-Do not weaken or move performance thresholds after seeing implementation results.
+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.
 
-## Transport discipline
+## Evidence and completion
 
-Do not invent a raw TCP protocol, new WebSocket protocol, QUIC layer or bespoke binary control format.
-
-The `.proto` schema is the semantic contract. Direct transport uses gRPC. Existing relay infrastructure may carry the same serialized protobuf frames as opaque binary.
-
-Protocol requirements:
-
-- Schema/version negotiation.
-- Request/work ID.
-- Route Session ID and route epoch.
-- Exact Model Artifact/runtime recipe fingerprint.
-- Shard range and effective overlap-safe start.
-- Prefill/decode/release/cancel phases.
-- Position/token range and idempotency step.
-- Named tensors with shape, dtype, byte order and bounded fragments.
-- Compression/checksum.
-- Cache expectation/result.
-- Deadlines, cancellation, flow control and structured status.
-
-Avoid per-token channel creation and unbounded unary payloads. Generated code and build tooling must be reproducible; do not require manual copying.
-
-## Native runtime discipline
-
-Reuse llama.cpp for GGUF, mmap, kernels, architecture graphs, tokenizer, KV, sequences and heterogeneous backends.
-
-The project patch stack is limited to:
-
-- Range-aware tensor registration/loading.
-- Endpoint-specific embedding/final head ownership.
-- Architecture-defined intermediate input/output.
-- Intermediate output before final norm/head.
-- Layer-filtered KV and session mapping.
-
-Do not place Meshnet routing, transport, billing or authentication inside llama.cpp. Keep patches numbered, scoped, pinned and upstreamable.
-
-Dense Llama is first only as a cheap range/boundary fixture. GLM-5.2 is the explicit product adapter and alpha target immediately afterward. Qwen3/Qwen3-MoE is post-alpha. Do not generalize through unchecked tensor-name substitutions.

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

+  -> GGUF mmap, upstream V4 graph/kernels, local per-shard state
 ```
 
-Weights never move in the per-request hot path. Every node opens and verifies its local Model Artifact before becoming routable.
+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.
 
-## Primary execution substrate
+## V4 boundary and state
 
-```text

-small exact-commit llama.cpp patch stack
-        |
-GGUF mmap, quantized kernels, architecture graphs,
-KV/sequence operations, CPU/CUDA/HIP/Vulkan/Metal backends
-```
+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.
 
-The patch stack adds only the missing local execution seam:
+## Concurrency, failure, and admission
 
-1. Range-aware tensor registration/loading.
-2. Endpoint-specific embedding and final head ownership.
-3. Architecture-defined intermediate input.
-4. Architecture-defined pre-tail boundary output.
-5. Layer-filtered KV and external session mapping.
-
-The worker owns protocol translation and process lifecycle. llama.cpp never receives Tracker, relay, billing or volunteer-network code.
-
-## Shard data plane
-
-Use Protocol Buffers and gRPC over HTTP/2.
-
-### Service shape
-
-- Unary capability and health.
-- Bidirectional Route Session stream.
-- Explicit release and cancellation.
-- Metrics suitable for capability admission and route scoring.
-
-### Session stream
-
-One long-lived stream represents one Route Session Activation Seam. It amortizes connection setup and inherits HTTP/2 flow control. Every message carries enough identity to reject stale or incompatible work.
-
-```text
-schema version
-request/work id
-Route Session id
-route epoch
-Model Artifact hash
-runtime recipe fingerprint
-Shard begin/end and effective start
-prefill/decode/release/cancel phase
-position and token range
-idempotency step id
-cache expectation/result
-named tensor bundle
-compression/checksum
-```
-
-Prefill tensors are split into bounded ordered frames. Decode messages carry one-step architecture boundary bundles and remain small. DGR-006 amends the current v1 decode fast path—which carries only one `NamedTensor`—to carry a versioned `TensorBundle`, while preserving compact one-tensor encoding and explicit compatibility behavior.
-
-Tail completion is not inferred from an activation tensor name. The protocol exposes a typed logits and/or sampled-token result, and exact sampling parameters plus chat-template/reasoning mode are bound to request/runtime identity.
-
-Direct nodes use gRPC. Nodes requiring the existing relay carry the same protobuf frames as opaque binary through the relay session. This preserves one semantic protocol instead of maintaining separate direct and relay payload contracts.
-
-## Architecture boundary
-
-The public boundary is a versioned named-tensor bundle:
-
-```text
-bundle schema/version
-architecture adapter and boundary point
-named tensors
-per-tensor shape, dtype and byte order
-payload fragments
-compression/checksum
-```
-
-Dense Llama may use one residual tensor. Other adapters may require more. vLLM's Llama and Qwen3-MoE PP paths demonstrate a boundary with both `hidden_states` and `residual`; therefore the generic protocol must not assume one anonymous tensor.
-
-GLM-5.2 normally exchanges a 6,144-element hidden state. If a memory-balanced Shard boundary splits an IndexShare Full producer from Shared consumers, the bundle also carries the typed top-k index sideband. The planner prefers boundaries that keep an IndexShare ownership group local, but the protocol validates the sideband rather than assuming it never crosses a seam.
-
-Only the head owns token embedding. Only the tail owns final normalization, LM head and sampling. Middle Shards exchange the architecture-defined pre-tail boundary, not final normalized embeddings.
-
-## Hot KV State and concurrency
-
-```text
-(Route Session id, route epoch)
-       -> local llama sequence or bounded context
-       -> KV for owned layers only
-       -> lease, memory accounting and lifecycle
-```
-
-Required operations:
-
-- Prefill append.
-- Decode append.
-- Truncate after rejected speculative positions if later enabled.
-- Explicit release.
-- TTL/LRU eviction.
-- Cache-miss response.
-- Stale-epoch rejection.
-
-A node must not clear global KV on a new stream or serialize all requests behind one logical serving sequence.
-
-## Continuous batching
-
-Autoregressive dependencies remain sequential inside one Route Session. Aggregate throughput comes from batching compatible decode steps across active sessions:
-
-```text
-time 0: session A token 1 + session B token 8 + session C token 3
-          -> one llama batch for this Shard
-
-time 1: next ready positions from active sessions
-          -> next llama batch
-```
-
-The node scheduler:
-
-- Admits work against weight, KV, scratch and queue budgets.
-- Keeps per-session token positions and outputs separate.
-- Prevents long prefill from starving decode.
-- Applies bounded backpressure.
-- Reports active sessions, queue depth, batch occupancy, KV pressure and throughput.
-
-The initial deterministic gate is four concurrent sessions on a small model without cross-talk. Hardware-specific limits are measured and advertised through capability admission.
-
-## Parallelism boundaries
-
-| Mechanism | First-runtime use |
-|---|---|
-| Layer/pipeline parallelism | Public Inference Route across contiguous Shards |
-| Continuous batching | Inside every node across active Route Sessions |
-| Data parallelism | Multiple complete routes for independent requests |
-| Tensor parallelism | Deferred to a trusted composite node/managed cluster |
-| Expert parallelism | Deferred to a trusted composite node/managed cluster |
-| Disaggregated prefill | Deferred until core route performance passes |
-| Speculative decoding | Deferred optimization |
-
-Public WAN tensor/expert collectives are rejected for the first runtime because their per-layer communication and static rank assumptions conflict with heterogeneous volunteer nodes.
-
-## Optional providers
-
-### Transformers/safetensors
-
-Remains:
-
-- Correctness/reference backend.
-- Fallback for unsupported architectures.
-- Baseline for performance and output quality.
-
-### vLLM
-
-May run unmodified as a complete model or managed TP/PP/EP cluster represented as one logical provider. Its internal ranks are not independently routed or rewarded.
-
-Borrow only concepts such as named bundles, continuous batching, typed compatibility fingerprints, explicit transfer lifecycle and load telemetry.
-
-### Whole-model llama.cpp
-
-Provides a local proxy backend, correctness oracle and performance baseline. It is not the native distributed milestone.
-
-## Artifact and recipe compatibility
-
-A routable recipe identifies separately:
-
-- Source Model Artifact hash and optional derivative/slice hash.
-- Architecture and adapter version.
-- Tokenizer revision and vocabulary.
-- Weight quantization.
-- Activation interchange dtype/schema.
-- Backend compute dtype and backend implementation.
-- KV dtype/layout.
-- RoPE/context parameters.
-- llama.cpp commit and project patch version.
-- Shard range and endpoint ownership.
-
-Compatibility fails closed. Similar quantization labels or model names are not enough.
-
-## Admission and failure
-
-A recipe becomes routable only after a real local and distributed forward passes. Synthetic tests remain unit coverage.
-
-Alpha failure behavior:
-
-- Deadline or node loss cancels the Route Session.
-- Every node releases KV and queued buffers.
-- Uncertain mutations are not replayed silently.
-- Retry starts from token zero on a newly compatible route.
-- No cross-node KV import is trusted until a later signed/compatible snapshot protocol exists.
-
-## Performance release contract
-
-Before native development proceeds, compare the current Transformers/safetensors backend with whole-model llama.cpp under controlled model/hardware/quality lanes.
-
-Final release compares distributed GGUF with distributed safetensors using thresholds locked before seeing final results.
-
-Required measurements:
-
-- TTFT.
-- Prefill and decode tokens/sec.
-- Aggregate concurrency throughput.
-- p50/p95 latency.
-- Seam bytes and latency.
-- Queue/batch occupancy.
-- RSS, VRAM and KV pressure.
-- Output-quality drift.
-- Cancellation/failure cleanup.
-
-The GGUF path ships only if it is faster at acceptable quality or enables a larger otherwise-unroutable model at useful measured speed.
-
-## Implementation sequence
-
-1. Preserve completed DGR-001 performance and DGR-002 protocol contracts.
-2. DGR-017 locks exact GLM-5.2 Max artifact, resource, and alpha acceptance identity.
-3. Define exact recipe identity and pin one reproducible llama.cpp boundary.
-4. Run two lanes in parallel: DGR-018 establishes the whole-model `UD-IQ1_S` oracle on 224+ GiB usable memory, while DGR-005/DGR-006 implement range loading and named boundary parity with a cheap dense fixture.
-5. DGR-019 adds explicit GLM-5.2 MoE/MLA/DSA/IndexShare semantics after both lanes pass.
-6. Implement local KV; build and integrate the standalone worker.
-7. Pass local two-process and real two-physical-machine execution.
-8. Harden cancellation, node loss, restart, and cleanup required by alpha.
-9. DGR-020 executes the exact multi-node target and emits immutable `alpha` or `stop`.
-10. Post-alpha: continuous batching, final comparison, longer context, MTP, and package optimization.
-11. Prepare narrow upstream patches/tests; add Qwen as later architecture expansion.
-
-See [the Ralph backlog](prd.json) and [implementation strategy](implementation-strategy.md).
+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
-
-> **Superseded for active implementation decisions.** The grill was resolved on 2026-07-13. Use [implementation-strategy.md](implementation-strategy.md), [architecture.md](architecture.md), [ADR-0020](ADR-0020-distributed-gguf-runtime.md), and [prd.json](prd.json). This file remains as historical decision rationale.
-
-This framework is for grilling open decisions. It keeps decisions tied to project vocabulary and implementation gates instead of vague "distributed inference" language.
-
-## Core Vocabulary
-
-Use the existing domain terms this way:
-
-- **Shard**: contiguous transformer layer range. This is the compute, routing, cache, and reward unit.
-- **Shard Swarm**: storage/download group for artifacts needed by a shard.
-- **Inference Route**: ordered node sequence that covers all layers for one request.
-- **Route Session**: one active request bound to one inference route and stable session id.
-- **Hot KV State**: live per-shard cache held by the route node during a route session.
-- **Prefix Snapshot**: persisted route-session state used for reuse or failover, not the hot decode path.
-- **Artifact Manifest**: canonical mapping from model artifacts to semantic model parts and runtime support.
-- **Generation Telemetry**: realtime progress for a route session, including phase and tokens/sec, independent of whether token deltas are streamed.

-## The Five Planes

-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

-
-### 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

-
-### 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`.

+# DGR-017 evidence — superseded backlog cleanup
 
-Status: **done**. Every acceptance criterion is met with real command output.
+**Completed:** 2026-07-16
+**Branch:** `ralph/distributed-gguf-runtime`
+**Planning checkpoint before cleanup:** `81b1fa6`
+**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
 
-Evidence class: **real upstream metadata + deterministic arithmetic**. No weight
-payload was downloaded, no model was loaded, no GPU was used, and no benchmark was
-run — and none is claimed. This story makes the target *reviewable before* the
-216.7 GB download, which is exactly its job.
+## Outcome
 
-## 1. Summary
+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 alpha target is now pinned, planned, and sealed:
+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.
 
-- **Identity.** `zai-org/GLM-5.2` @ `b4734de4facf877f85769a911abafc5283eab3d9` and
-  `unsloth/GLM-5.2-GGUF` @ `abc55e72527792c6e77069c99b4cb7de16fa9f23`, quantization
-  `UD-IQ1_S`, six shards, 216,715,360,960 bytes, every shard's LFS SHA-256 resolved.
-- **Architecture.** The config/tokenizer/chat-template metadata the runtime cannot
-  shard without, hashed at the pinned revision.
-- **Resources.** A deterministic planner that counts unified memory once, applies the
-  `max(20% , 8 GiB)` reserve, and reports the arithmetic minimum and the recommended
-  node count as two different numbers.
-- **Contract.** The roadmap's section-5 acceptance matrix as a machine-readable,
-  digest-sealed document, locked before the target ever runs and cross-bound to the
-  exact manifest and architecture-snapshot digests.
-- **Upstream.** A refreshed llama.cpp/donor status report.
+## Classification and disposition
 
-Three findings are worth a reader's attention.
+### Retained
 
-**Every number in the roadmap reproduced from primary sources.** The 216,715,360,960
-byte total, the 201.832 GiB figure, the whole KV table (0.73 / 0.77 / 0.89 / 1.68 GiB
-at 16K, through 46.62 / 49.41 / 56.98 / 107.25 GiB at 1M), and the whole tier table
-(9 / 6 / 4 / 3 / 2 arithmetic minimum nodes) fall out of the exact config and the
-exact shard bytes. The roadmap was not approximating. The planner is written as a
-*reproduction* of those tables, so if the arithmetic ever stops matching, a test says
-which numbers moved.
+- 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.
 
-**The roadmap's "recommended" column is an imbalance factor of exactly 1.10.** Nodes
-= `ceil(total x 1.10 / budget)` yields 10 / 6 / 5 / 3 / 3 for the 32 / 48 / 64 / 96 /
-128 GiB tiers — precisely the roadmap's recommendations. That constant is now named
-(`PLACEMENT_IMBALANCE_FACTOR`) and documented as a placeholder for measured
-per-tensor placement, not a fudge factor to be tuned once results are in.
+### Removed from the active tree
 
-**224 GiB aggregate does not actually fit.** Two 112 GiB nodes hit the 224 GiB
-"hard-fit floor" exactly, and still come up **23.5 GiB short** once each node honours
-its reserve. That is what makes 224 GiB an *experimental floor* rather than an
-envelope, and it is now a test, not a caveat in prose. Relatedly, the 2×128 and 4×64
-"fit probe" topologies fit with only **2.08 GiB of headroom across the entire route** —
-which is why they require measured placement evidence and are not the recommendation.
+- 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.
 
-## 2. Files changed
+### Confirmed absent and still required
 
-New — runtime-loadable package (single source of truth):
+- 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.

-Controller review found and fixed four gaps before the commit was accepted:
+Result:
 
-1. the initial wheel omitted `glm_alpha/data/*.json`, despite source-tree tests passing;
-2. the self-sealed contract did not bind the manifest/snapshot digests, so coordinated
-   shard-hash or architecture substitutions could be accepted;
-3. `--check` followed moving repository HEAD instead of validating immutable pins;
-4. non-finite resource telemetry could bypass ordinary range checks.
+```text
+216 passed, 2 skipped, 1 failed, 1 warning
+```
 
-Each failure now has either an adversarial regression test or a real installed-wheel /
-live-metadata gate. None of the provisional agent results were accepted on trust.
+The failure was a synthetic capability-test helper `KeyError: 'compatibility_fingerprint'`. The warning was a pre-existing heartbeat-thread `SystemExit` warning.
 
-The intermittent tracker cancellation race that DGR-001 and DGR-002 both recorded as
-flaky on a clean tree failed once in the final validation (`404` after the request
-completed), then passed **5/5** in isolation and passed in the integrated full-suite
-rerun above. This story touches no tracker code; the failed run is retained in
-`commands.txt` rather than hidden.
+## Cleanup verification
 
-### 4a. Late independent-review repair (2026-07-14)
+### Source equality
 
-During delayed DGR-003 review, two contract-continuity defects were found and
-fixed here: v1 now has an independently trusted digest pinned in code
-(`test_resealing_a_mutated_v1_contract_is_rejected`) and parsed nested contract
-state is recursively immutable. This added two tests; the suite is now
-**99 passed** (`commands.txt` §7 records the exact runs). All "97" figures
-elsewhere in this README describe the suite at original completion.

+### Cleanup-relevant regression suite
 
-**Contract continuity is fail-closed.** The document’s `contract_sha256` detects
-accidental edits, and the approved v1 digest is pinned independently in code. A caller
-that changes a threshold and re-seals it under `glm-5.2-max-alpha/v1` is rejected by
-`test_resealing_a_mutated_v1_contract_is_rejected`; amendments require a new supported
-contract identity under human review. Parsed nested state is recursively immutable,
-so thresholds cannot change between validation and use; `to_dict()` returns an isolated
-copy rather than exposing the validated object.

-- #24730 still OPEN — the umbrella GLM-5.2 support request.
+```text
+119 passed, 2 skipped, 1 warning in 15.90s
+```
 
-**No released upstream llama.cpp performs native GLM-5.2 DSA + IndexShare today.** A
-stock pin taken now would load the artifact and emit text through the dense fallback —
-which the alpha contract explicitly refuses (`dense_attention_fallback_satisfies_alpha:
-false`). DGR-018 must therefore prove those paths are *active*, not that output appeared.
+The warning is the same pre-existing heartbeat-thread `SystemExit` warning.
 
-Donor policy holds, and the evidence now supports it more strongly than before: PR
-#25407 is **12 files, +414/−7**. The semantics alpha needs are small enough to track
-and reproduce upstream. That is the argument against adopting Mesh-LLM's 261-patch
-fork — recorded as a donor (Apache-2.0, branch head `9bd18f15`, 2026-07-12), nothing
-adopted here.
+### Known `origin/master` limitations
 
-## 7. Limitations and deferred work
+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:
 
-- **No artifact was downloaded or loaded.** Sizes and SHA-256 come from Hugging Face
-  LFS pointer metadata. DGR-018 must verify the digests against the real files on
-  mounted storage before route admission. A matching size with a wrong hash is exactly
-  the failure this manifest exists to catch, and only a local verify can catch it.
-- **`PLACEMENT_IMBALANCE_FACTOR = 1.10` is a planning assumption, not a measurement.**
-  It reproduces the roadmap's recommendations, but the real per-node share depends on
-  exact tensor bytes (embeddings, output head, dense vs MoE layers, shared experts,
-  indexer tensors, quant block alignment). DGR-019 must replace it with measured
-  placement. Until then, arithmetic-minimum topologies (2×128, 4×64) stay fit probes.
-- **KV numbers are planning estimates, not admission truth.** The planner deliberately
-  budgets the *conservative* indexer layout (keys across all 78 layers, not just the 21
-  Full ones) so a route admitted here cannot be surprised by the implementation it
-  actually gets. The runtime must still report measured allocated/resident MLA and
-  indexer cache per shard.
-- **Peak scratch is unmodelled.** The reserve exists precisely because backend
-  workspaces and graph scratch are not predictable from the artifact; measured peak
-  must land inside the reserve, and the contract requires that evidence.
-- **Upstream is moving fast.** #25407 was updated the same day it was observed. Refresh
-  `upstream-status.json` before DGR-004 picks a llama.cpp pin. The manifest script's
-  `--check` deliberately validates the immutable Hugging Face pins, not moving HEAD.

-## 8. Compatibility and migration notes
+They are recorded as pre-existing baseline defects and were not repaired or hidden by this cleanup story.
 
-- Purely additive. No existing module, wire format, or test changed. Nothing in this
-  story is on a live request path.
-- `meshnet_node.glm_alpha` has **no heavy imports** — no torch, no transformers, no
-  network at import time — so a tracker or planner can read the target contract without
-  paying for a model runtime.
-- Re-pinning is deliberately awkward: `--write` follows current HEAD and leaves the
-  existing contract binding invalid until a new contract is reviewed and sealed.
-  `--check` uses revision-specific APIs and exits non-zero rather than healing any
-  integrity drift in the already locked target.
+## Dependency handoff
 
-## 9. Handoff to dependent stories
-
-**DGR-003 (recipe identity):** fold `TargetManifest.digest`
-(`0b6aed04479d204902bb64c0203f1a46cab26a47b378ecccf85237b63f6c1962`) and
-`ArchitectureSnapshot.digest` (`253fbd94…`) into the runtime recipe fingerprint. The
-GLM fields the roadmap asks you to add (DSA/IndexShare metadata, context max, expert
-counts) are already resolved in `architecture-snapshot.json` — read them, do not
-re-derive them by hand. Populate the DGR-002 `Fingerprint` message; do not invent a
-second identity struct.
-
-**DGR-004 (llama.cpp pin):** read `upstream-status.json` first. Any pin taken before
-#25407 merges gives you the dense-MLA fallback, which cannot satisfy alpha. Track
-#25407 (12 files) as a numbered patch; do not adopt the Mesh-LLM fork.
-
-**DGR-018 (whole-model oracle):** the six digests in `target-manifest.json` are what you
-verify the download against. Your host needs ≥224 GiB runtime-accessible memory — and
-note that 224 GiB is the *floor*, not a comfortable target (see §1). Prove DSA,
-IndexShare, shared expert, and the Max template are **active**; the contract's
-`require_rendered_reasoning_effort_marker` is `<|system|>Reasoning Effort: Max`. Assert
-the rendered marker, not the request field: the template's only non-max level is
-`'high'`, so *every other value — including an absent one — renders Max*, and "the
-request said max" proves nothing.
-
-**DGR-019 (GLM semantics):** the IndexShare split is **21 Full producer layers and 57
-Shared consumers**, in a `[full, full, full] + repeating [shared, shared, shared, full]`
-pattern. Prefer shard boundaries that keep an ownership group whole; the 8 KiB
-(2048 × int32) top-k sideband is the cost when you cannot. Replace
-`PLACEMENT_IMBALANCE_FACTOR` with measured per-tensor placement.
-
-**DGR-020 (alpha verdict):** load the target with `load_locked_target()`. It verifies
-the contract seal and cross-binds the manifest and architecture snapshot before
-returning them. Judge against
-`contract.threshold(section, key)` — an unlocked threshold raises rather than
-defaulting, so a criterion cannot be invented at read time. The verdict is `alpha` or
-`stop`; there is no third outcome, and a quality pass with a speed failure is `stop`.
-
-**Everyone:** unified system RAM and integrated-GPU memory are one pool. Build nodes
-with `NodeMemory.from_host(..., unified=True)` and it is impossible to write the
-double-count; pass a GPU size alongside `unified=True` and it raises rather than
-silently ignoring the argument.
+DGR-018 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 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.

+Freeze useful-speed, correctness, memory-fit, and stop/go thresholds for the DeepSeek V4 Flash
+distributed GGUF track *before* any distributed implementation produces a benchmark result, per
+`.scratch/distributed-gguf-runtime/issues/019-lock-alpha-and-beta-performance-contracts.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 `47bad0b`), 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 (replacing them with only a bare `metadata: {"updatedAt": ...}` stamp), while `userStories`
+itself was byte-identical to `HEAD`. Running `tests/test_ralph_prd_schema.py` against the
+as-found working tree confirmed the damage: 56 of 108 tests failed (every
+`test_render_issue_markdown_matches_committed_file[...]` parametrization, since
+`quality_gate_bullets`/`authority_disclaimer` fall back to module defaults once `qualityGates`/
+`metadataSchema` are absent, which no longer match the committed issue files).
+
+This is the same shape of problem DGR-018's evidence documented and fixed: an abandoned,
+unexplained edit that silently dropped the schema/gates/milestone/provenance content this and
+future stories depend on, while `scripts/ralph_prd_schema.py validate` did not catch it (those
+top-level sections are optional-if-absent by design, so the CLI reported `OK: 55 stories
+validated.` even with them missing). The most likely cause is `ralph-tui`'s own read/write of
+`prd.json` as its task source, which only round-trips the fields it models
+(`name`/`description`/`branchName`/`userStories`) and stamps its own `metadata.updatedAt`,
+dropping any project-specific extension fields it doesn't know about.
+
+Per `RALPH-CONTEXT.md`'s instruction to inspect `git status` and preserve unrelated work rather
+than build on top of unexplained state, and following the DGR-018 precedent, the dropped fields
+were restored verbatim from `HEAD` (`git show HEAD:.scratch/distributed-gguf-runtime/prd.json`)
+while keeping the current `userStories` content (identical) and the current `metadata.updatedAt`
+stamp. `tests/test_ralph_prd_schema.py` returned to `108 passed` immediately after the restore,
+before any DGR-019-specific change was made.
+
+## Changes
+
+### `packages/node/meshnet_node/dgr_performance/` (new package)
+
+- **`data/alpha-beta-contract-v1.json`** — the locked, versioned, machine-readable contract.
+  `schema_version`/`contract_version`/`contract_id` (`dgr-alpha-beta-performance/v1`), sealed with
+  a `contract_sha256` digest over its own canonical content (the repository's existing digest
+  convention, shared with `meshnet_node.glm_alpha.contract`). Contents:
+  - `prompt_set` — four fixed prompts (`short-instruction`, `code-completion`,
+    `multi-step-reasoning`, `long-context-fill`) referenced by ID from every lane, so no lane can
+    quietly drift onto a different workload.
+  - `sampling` — greedy (`temperature=0`, `top_p=1`, `top_k=1`, `seed=1234`), matching
+    `meshnet_node.recipe_benchmark.SamplingPolicy` defaults.
+  - `lanes` — all four lanes named in the acceptance criteria. `controlled-safetensors` and
+    `whole-model-gguf` are marked `locked_elsewhere: true` and point at the pre-existing immutable
+    DGR-001 lock (`meshnet_node.performance_contract`, `contract_version=1`,
+    `ContractThresholds`) rather than re-defining or risking a conflicting duplicate. Only
+    `dense-distributed-gguf` and `v4-flash-distributed` are newly locked here, each with fixed
+    `prompt_ids`, `context_tokens`/`output_tokens` (alpha- and beta-scale for the V4 lane),
+    `concurrency_levels`, `hardware` (named certification-scenario topology, network class, device
+    class, MTP-off note), and a `metrics` list drawn from the existing
+    `recipe_benchmark`/`performance_contract`/`route_session_benchmark` metric vocabulary
+    (`ttft_p50_ms`, `decode_tokens_per_sec`, `seam_bytes`, `seam_latency_ms`, ...).
+  - `gain_attribution` — two disjoint metric sets, `quantization_model_fit_metrics` and
+    `runtime_transport_batching_kernel_metrics`, plus the rule that a speed/fit claim must cite
+    which axis moved it.
+  - `certification_scenarios` — `quantization` (`Q4_K_M`, `Q8_0`, `bf16-reference`) and
+    `stage_count` (`2-4-stage`, `10-plus-stage`) as named labels only, with an explicit rule that
+    no product/runtime code path may hardcode them.
+  - `alpha` — correctness thresholds (greedy token agreement, mean state cosine similarity,
+    nonfinite-tensor/fail-closed checks, no dense-attention-fallback credit) plus a `useful_speed`
+    block whose ratios (`1.25`/`0.75`-class, matching the already-locked DGR-001 25% convention)
+    carry an explicit `human_approval` sub-block (`required: true`, `approved: false`,
+    `approved_by: null`, `approved_at: null`). The ratio alone cannot satisfy alpha; DGR-054 must
+    fill in the approval against real evidence. `mtp.reserved=true`/`enabled_for_alpha=false` per
+    `RALPH-CONTEXT.md`. `verdicts: ["alpha", "optimize", "stop"]`.
+  - `beta` — adds exactly `concurrency`, `long_context`, `failure`, `sustained_throughput` axes
+    (16k-token long-context threshold matching the V4 lane's `beta_context_tokens`, no-silent-KV-
+    migration and no-synthetic-workers failure rules, 30-minute sustained-throughput floor).
+    `verdicts: ["beta", "targeted-optimization", "stop-rollback"]`.
+  - `amendment_policy` — thresholds may not be weakened/moved/reinterpreted after results are
+    known; a change requires a new `contract_id`/`contract_version` under human review.
+- **`contract.py`** — loader/validator mirroring the proven
+  `meshnet_node.glm_alpha.contract` pattern: `parse_contract` recomputes the canonical-JSON SHA-256
+  over the document (excluding the digest field) and requires it match both the document's own
+  declared `contract_sha256` *and* a digest pinned independently in code
+  (`CONTRACT_V1_SHA256`), so neither an in-place edit nor a resealed mutation can pass silently.
+  Structural checks enforce all four required lanes, that the two referenced lanes actually
+  declare `locked_elsewhere`, that the two newly-locked lanes carry full benchmark-plan fields,
+  that `alpha.verdicts`/`beta.verdicts` are exactly the three-outcome sets the release gates use,
+  and — the one property with no analogue in `glm_alpha` — that
+  `alpha.useful_speed.human_approval.required` is `true`. `seal_contract()` is the only supported
+  way to produce a new digest, kept separate from load-time verification for the same reason
+  `glm_alpha` keeps it separate.
+- **`__init__.py`** — re-exports the public API, documented as the contract DGR-020, DGR-044,
+  DGR-054, and DGR-070 are judged against.
+
+### `tests/test_dgr_performance_contract.py` (new, 28 tests)
+
+Deterministic, offline, GPU-free, model-download-free. Covers: packaged load and identity; digest
+recomputation; all four lanes present; the two referenced lanes point at the real DGR-001 module
+and its actual immutable thresholds (`min_decode_speedup == 1.25`, `max_resident_memory_ratio ==
+0.75`); the two newly-locked lanes carry complete benchmark plans, fixed context/output/
+concurrency; the shared prompt set and every lane's `prompt_ids`/`beta_prompt_ids` are a subset of
+it; sampling is greedy; `gain_attribution`'s two metric sets are non-empty and disjoint;
+certification-scenario names and rule text; **a structural test that greps every `.py` file under
+`packages/node/meshnet_node` (excluding this contract's own module and data file) for the literal
+strings `2-4-stage`/`10-plus-stage` and fails if any product module hardcodes them** — the concrete
+form of "no product logic may hardcode them"; alpha verdicts/correctness/`human_approval`/MTP-off;
+beta verdicts/axes/long-context/failure semantics; digest-mutation rejection (in-place and
+resealed); missing-digest rejection; `load_contract` from an explicit path matches the packaged
+load; `seal_contract` reproduces the pinned digest; amendment policy text.
+
+### `.scratch/distributed-gguf-runtime/prd.json`
+
+- Restored the top-level `sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/
+  `supersededStories` objects dropped by the pre-existing unrelated edit (see above); kept the
+  current `metadata.updatedAt` tooling stamp.
+- Marked `DGR-019.passes = true` with `completionNotes` summarizing this outcome.
+
+### `.scratch/distributed-gguf-runtime/issues/019-lock-alpha-and-beta-performance-contracts.md`
+
+Regenerated via `python scripts/ralph_prd_schema.py render` to reflect `passes: true` (checked
+acceptance criteria, "completed" status line, "Verified evidence" handoff line), matching the
+convention DGR-017/DGR-018's issue files already use.

+This full sweep was launched in the background while `prd.json`/the evidence README below were

+(`test_ralph_prd_schema.py::test_real_backlog_passed_stories_have_completion_evidence`) was this
+story's own `passes=true`/evidence-README edit landing mid-run, not a real defect — re-running
+`tests/test_ralph_prd_schema.py` alone afterward, against the finalized tree, gives
+`108 passed`. The other 6 failures (`test_billing_ledger.py::

+HEAD -- tests/test_billing_ledger.py tests/test_dynamic_routing.py tests/test_real_model_backend.py`
+is empty) and none of them import `dgr_performance`, `performance_contract`, or `glm_alpha`; they
+are pre-existing baseline defects, not regressions from this story, in the same spirit as the
+known `origin/master` limitations DGR-017's evidence recorded.
+
+## Known limitations
+
+- `tests/test_shard_runtime_harness.py` fails to *collect* in this environment
+  (`ModuleNotFoundError: No module named 'grpc'`). This is a pre-existing environment gap from
+  DGR-024's real generated-gRPC protocol harness, not something this story touched or caused; it is
+  excluded from the sweep above rather than silently masked.
+- Alpha's `useful_speed` ratios (`1.25`/`0.75`-class) are proposed thresholds held at the same
+  margin already locked for the whole-model contract (DGR-001/v1). They are locked numbers, but
+  `human_approval.required=true` means DGR-054 may not treat them as self-certifying from the
+  ratio alone — a human must approve the observed ratio against real evidence. This session did
+  not, and could not, supply that approval: no distributed benchmark evidence exists yet.
+- `v4-flash-distributed`'s `reference_baseline` documents that a safetensors DeepSeek V4 Flash
+  distributed baseline may not yet be pinned (that is DGR-044's job); until then, comparisons must
+  fall back to `dense-distributed-gguf` runtime/transport overhead as an explicit, stated
+  limitation rather than a silent substitution.
+- This is a specification-materialization story; per the shared quality gates, it is intentionally
+  left uncommitted for manual review rather than given the "one scoped story commit" other stories
+  get.
+
+## Dependency handoff
+
+DGR-020 (run the controlled whole-model baseline) consumes the DGR-001 lock referenced — not
+redefined — by this contract's `controlled-safetensors`/`whole-model-gguf` lanes.
+
+DGR-044 (pin the DeepSeek V4 Flash target contract) and DGR-054/DGR-070 (enforce the alpha/beta
+gates) must load `meshnet_node.dgr_performance.load_contract()` and judge results against its
+`dense-distributed-gguf`/`v4-flash-distributed` lanes and `alpha`/`beta` sections without changing
+any threshold. DGR-054 specifically must populate `alpha.useful_speed.human_approval`
+(`approved`/`approved_by`/`approved_at`) as part of publishing its verdict — a satisfied ratio
+without a filled-in approval is not alpha certification. Any amendment must open a new
+`contract_id`/`contract_version` under human review per `amendment_policy`; this document and its
+digest are not editable in place.

+# DGR-020 evidence — run the controlled whole-model GGUF baseline
+
+**Completed:** 2026-07-22
+**Branch:** `ralph/distributed-gguf-runtime`
+**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
+**Dependency:** DGR-019 (`evidence/DGR-019/README.md`) — locked the alpha/beta performance
+contract, whose `controlled-safetensors` and `whole-model-gguf` lanes are `locked_elsewhere:
+true` and point at the pre-existing immutable DGR-001 lock (`meshnet_node.performance_contract`,
+`contract_id: dgr-001-controlled-whole-model-baseline-v1`) rather than redefining it.
+
+## Objective
+
+Per `.scratch/distributed-gguf-runtime/issues/020-run-the-controlled-whole-model-gguf-baseline.md`:
+execute the exact locked safetensors and whole-model llama.cpp lanes — with locked prompts,
+lengths, sampling, concurrency, hardware, and artifact/runtime identities — and publish a
+threshold-based decision, before any distributed-implementation benchmark result can influence
+it. Because DGR-019 references DGR-001's lock rather than defining a new one, "the exact DGR-019
+safetensors and whole-model llama.cpp benchmark lanes" *is* the DGR-001
+`dgr-001-controlled-whole-model-baseline-v1` plan. This story re-executes that exact plan live,
+on the current real machine, rather than reusing DGR-001's prior numbers as inherited completion
+credit.
+
+## Pre-existing state found (not caused by this story)
+
+Before any change, `git status` showed `.scratch/distributed-gguf-runtime/prd.json` already
+modified relative to `HEAD` (`47bad0b`). Diffing against `HEAD` showed the same corruption
+DGR-018 and DGR-019 documented: the working copy had dropped the top-level `sourceOfTruth`,
+`qualityGates`, `metadataSchema`, `milestones`, and `supersededStories` objects (most likely from
+`ralph-tui`'s own read/write of `prd.json`, which round-trips only the fields it models). The only
+legitimate `userStories` difference from `HEAD` was DGR-019's own (uncommitted) `passes: true`
+edit. Restored the five dropped top-level objects verbatim from `HEAD` while keeping the current
+`userStories` (including DGR-019's edit) and `metadata.updatedAt`. `tests/test_ralph_prd_schema.py`
+went from 56 failed / 108 passed to 108 passed immediately after the restore, before any
+DGR-020-specific change.
+
+## Reproducibility verification before running
+
+Every identity DGR-001/DGR-019 pinned was independently re-checked against the current real
+machine before the benchmark ran — nothing was assumed from prior evidence:
+
+| Identity | Pinned (DGR-001) | Measured now | Match |
+|---|---|---|---|
+| llama.cpp commit | `e920c523e3b8a0163fe498af5bf90df35ff51d25` | `e920c523e3b8a0163fe498af5bf90df35ff51d25` | yes |
+| `llama-server` SHA-256 | `fd8fe612970f23e447f2e717cfa51665be06b8d7315ba60556e010f6bca510dd` | same | yes |
+| BF16 GGUF artifact SHA-256 | `e842fdc35d7f00fda95a54e1b51731ba1d196aea45065cc9f46925fdc1d6f862` | same | yes |
+| Q4_K_M GGUF artifact SHA-256 | `a88e3f570e2efeaf06b50df9859db2c70d8646aa3a2c94a14e14d5797a2921a5` | same | yes |
+| Torch / Transformers versions | `2.10.0+rocm7.13.0a20260513` / `5.13.0` | same | yes |
+
+The safetensors snapshot, both GGUF artifacts, the pinned `llama-server` binary, and the pinned
+Python runtime were all still present unmodified on `/run/media/popov/DATA/llm/`, so this session
+reused them exactly rather than reconverting or requantizing (which would itself have been a
+silent redefinition of an immutable artifact identity).
+
+## Real results — fresh run on real hardware
+
+`.scratch/distributed-gguf-runtime/evidence/DGR-020/benchmark-config.json` and
+`performance-contract.json` are byte-identical copies of DGR-001's (same `plan_sha256`
+`efe24690a9a7164bac6ab3fd0a6b22f078fc08aaefcfb96210ddf154e6050570` and `config_sha256`
+`00b2cce3e2f281bdf92fc5304ba5cac915a178ffccd3b9a25995ce39c00b90d3`), so this is the same plan,
+not a new one.
+
+```bash

+
+All three recipes completed every request with zero failures, on CPU, `fedora`
+`7.0.14-101.fc43.x86_64`, 32 logical CPUs:
+
+| Metric | Transformers BF16 (ref) | llama.cpp BF16 | llama.cpp Q4_K_M | DGR-001 (prior run, same plan) |
+|---|---:|---:|---:|---|
+| Decode tok/s, c=1 | 50.8 | 102.5 | 213.1 | 40.8 / 98.5 / 207.7 |

+| Mean similarity vs reference | — | 0.9471 | 0.456 (advisory) | 0.9471 |
+
+Per-recipe measurements against the reference (`baseline.json`, `contract-evaluation.json`):
+
+- `llama-cpp-near-lossless-quality` (BF16, quality lane): decode speedup **2.02x**, aggregate
+  throughput speedup (c=4) **4.47x**, resident-memory ratio **0.574x**, TTFT ratio **0.459x** —
+  but `quality_pass: false` (exact match 0.33 < required 0.90).
+- `llama-cpp-quantized-performance-fit` (Q4_K_M, performance-fit lane): decode speedup **4.19x**,
+  aggregate throughput speedup (c=4) **4.83x**, resident-memory ratio **0.280x**, artifact-size
+  ratio **0.398x**, TTFT ratio **0.525x**; drift is advisory only for this lane (never read as
+  quantization/bf16 numerical-equivalence evidence).
+
+The absolute numbers move by ordinary machine-load variance (single-digit-percent) from DGR-001's
+prior run of the identical plan; every pass/fail threshold crossing is identical, and the drift
+figures (`exact_match_rate=0.3333`, `mean_similarity=0.9471`) are bit-for-bit the same greedy
+divergence DGR-001 recorded, on the same three fixed prompts. This is a genuine independent
+reproduction, not a copy: `results.json`'s `provenance.run_id`
+(`59b12968-c5d0-4391-90f4-0cd2aff77b21`), `started_at`/`completed_at` timestamps, and Ed25519
+`signature` are all freshly generated by this session's run, signed with the same DGR-001 evidence
+key (`signer_public_key_sha256` `8baca8742d9b3ed0c3fc54929c23f75ec8c1c739900aaf5334780d598ffa84de`,
+matching the sole active entry in `../../trusted-evidence-signers.json`).
+
+## Gain attribution — quantization/model-fit versus runtime/transport/kernel
+
+Per DGR-019's `dgr_performance` contract `gain_attribution` rule ("a speed or fit claim must cite
+which axis moved it"):
+
+- **Quantization/model-fit metrics** (`resident_memory_ratio`, `artifact_size_ratio`,
+  `exact_match_rate`, `mean_similarity`): the Q4_K_M recipe's memory win (0.280x) and size win
+  (0.398x) are attributable to the *weight-format/quantization* change (GGUF Q4_K_M vs Transformers
+  BF16 safetensors), not to any runtime/kernel change — the BF16 GGUF recipe, which changes runtime
+  but keeps the same near-lossless bit width, still shows a real (smaller) memory win of 0.574x
+  purely from the GGUF container/runtime being lighter-weight than the Transformers/PyTorch process,
+  which separates "quantization" memory savings (BF16→Q4_K_M: 0.574x→0.280x) from "runtime/format"
+  memory savings (safetensors→BF16 GGUF: 1.0x→0.574x). The quality-lane failure
+  (`exact_match_rate=0.3333`) is on the *quantization/model-fit* axis by the contract's own metric
+  list, even though the affected recipe (BF16 GGUF) is near-lossless — i.e. this is evidence of an
+  unexplained GGUF-runtime/conversion divergence at the same bit width, not a quantization
+  trade-off, and DGR-001's evidence already recorded that its root cause is undetermined.
+- **Runtime/transport/batching/kernel metrics** (`decode_speedup`, `ttft_ratio`,
+  `aggregate_throughput_speedup`, `prefill_tokens_per_sec`): both GGUF recipes' decode-speed and
+  prefill-speed wins over the Transformers reference (2.02x/4.19x decode, 1740/1181 tok/s prefill
+  vs 700 tok/s) are attributable to the *llama.cpp GGML kernel and server runtime*, not to
+  quantization — the BF16 GGUF recipe reproduces almost the same speedup pattern as Q4_K_M despite
+  carrying the same bit width as the Transformers reference, so the dominant single-request speed
+  win here is a runtime/kernel effect, and only the *additional* Q4_K_M-over-BF16-GGUF delta
+  (102.5→213.1 tok/s decode, ~2.08x) is attributable to quantization on top of that runtime effect.
+  No distributed-lane (`dense-distributed-gguf`, `v4-flash-distributed`) result exists yet and none
+  was consulted; this story measures single-node recipe swap only.
+
+## Failed / unavailable lanes
+
+None. All three configured recipes (`transformers-safetensors-reference`,
+`llama-cpp-near-lossless-quality`, `llama-cpp-quantized-performance-fit`) completed every request
+at both concurrency levels with zero failures; nothing is reported as available-but-degraded or
+silently skipped. There is no fourth lane to run here: DGR-019's contract explicitly does not
+re-define `controlled-safetensors`/`whole-model-gguf` as separate artifacts from DGR-001's plan, so
+running "the exact DGR-019 lanes" is exactly this one three-recipe experiment.

+```
+
+Mapped to this story's `go` / `optimize baseline` / `stop` vocabulary: **stop**. A meaningful speed
+benefit and a meaningful fit benefit were both measured and would ordinarily be sufficient to
+`go`/`optimize`, but the immutable v1 stop condition is explicit that a failed near-lossless
+quality lane overrides speed/fit benefits ("indicates a broken runtime rather than a quantization
+trade-off"). This decision uses only the locked v1 thresholds and this session's freshly measured
+metrics; no threshold was changed, and no distributed-implementation result (DGR-024's gRPC
+harness or any other distributed-lane evidence) was read or ingested to produce it.
+
+This reproduces DGR-001's original `stop` verdict on the same plan on the same real machine,
+confirming that verdict is stable over time and not an artifact of a single run.
+
+## Limitations
+
+- This is a **0.5B CPU baseline** (`Qwen/Qwen2.5-0.5B-Instruct`), the same generic model DGR-001
+  and DGR-019's `locked_elsewhere` reference use — not DeepSeek V4 Flash. DGR-019's evidence
+  already recorded that a DeepSeek V4 Flash `controlled-safetensors`/`whole-model-gguf` baseline is
+  not yet pinned; that is separate future work (see DGR-019's `v4-flash-distributed.reference_
+  baseline` note), not something this story's acceptance criteria ask it to create — it asks only
+  to run the exact already-locked lanes, which are this DGR-001 plan.
+  - The `whole-model-gguf` quality-lane exact-match divergence (0.33 vs 0.90 required) reproduces
+  identically and remains unexplained; this story does not diagnose it further beyond confirming
+  it reproduces (DGR-001's `quality-parity-diagnosis.md` documents the CPU-vs-ROCm split already
+  known).
+- Absolute timings are single-developer-machine measurements with ordinary run-to-run variance;
+  the locked ratios/ratios-vs-threshold crossings are the durable evidence, not the raw absolute
+  tok/s figures.
+- No new GPU (ROCm) diagnostic was re-run in this session — DGR-001's existing GPU diagnostic is
+  cited as prior evidence only; it uses a distinct signed `run_configured_gpu_diagnostic/v1`
+  producer that the v1 evaluator does not accept, so it cannot itself change the `stop` verdict
+  above.
+
+## Files changed
+
+- `.scratch/distributed-gguf-runtime/evidence/DGR-020/benchmark-config.json` (new) — byte-identical
+  copy of DGR-001's locked plan.
+- `.scratch/distributed-gguf-runtime/evidence/DGR-020/performance-contract.json` (new) —
+  byte-identical copy of DGR-001's immutable v1 thresholds.
+- `.scratch/distributed-gguf-runtime/evidence/DGR-020/results.json` / `results.txt` (new) — raw
+  signed real evidence from this session's fresh run.
+- `.scratch/distributed-gguf-runtime/evidence/DGR-020/baseline.json` / `contract-evaluation.json`
+  (new) — distilled baseline and fail-closed v1 verdict for this session's run.
+- `.scratch/distributed-gguf-runtime/evidence/DGR-020/README.md` (new, this file).
+- `.scratch/distributed-gguf-runtime/prd.json` — restored the dropped top-level
+  `sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/`supersededStories` objects (see
+  above); marked `DGR-020.passes = true` with `completionNotes`.
+- `.scratch/distributed-gguf-runtime/issues/020-run-the-controlled-whole-model-gguf-baseline.md` —
+  regenerated via `python scripts/ralph_prd_schema.py render` to reflect `passes: true`.
+
+No source or test files under `packages/` or `tests/` were changed by this story.

+## Dependency handoff
+
+DGR-054 (enforce the alpha gate) may cite this evidence when it fills in
+`alpha.useful_speed.human_approval` — this is fresh, independently-collected, signed real-hardware
+evidence that the `controlled-safetensors`/`whole-model-gguf` v1 contract still holds `stop` on the
+current machine, immediately before any distributed-lane result exists, but it is a 0.5B CPU
+baseline, not the DeepSeek V4 Flash target; DGR-044 must still pin the V4 Flash reference baseline
+separately before DGR-054/DGR-070 can judge `dense-distributed-gguf`/`v4-flash-distributed` against
+it. No threshold in either `meshnet_node.performance_contract` or `meshnet_node.dgr_performance`
+was changed by this story.

+# DGR-021 evidence — versioned named-tensor activation envelope
+
+**Completed:** 2026-07-17
+**Branch:** `distributed-gguf-runtime`
+**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
+**Dependency:** DGR-018 (`evidence/DGR-018/README.md`) — canonical backlog schema / issue projection contract
+
+## Objective
+
+Establish the backend-neutral activation envelope used by direct and relayed Shard traffic, with stable versioning, named tensors, bounded fragmentation, checksum validation, and reserved extensibility for future state.
+
+## Changes
+
+### `packages/node/meshnet_node/protocol.py` (new)
+
+Added a self-contained activation-envelope module with:
+
+- `SCHEMA_NAME = "meshnet.activation-stream"` and `SCHEMA_VERSION = 1`
+- `TensorFragment`
+  - bounded byte fragments with offset, compression tag, checksum, and extension preservation
+  - deterministic `to_dict()` / `from_dict()` round-trip
+- `NamedTensor`
+  - named tensor metadata: `name`, `shape`, `dtype`, `byte_order`, `compression`, `checksum`, `fragments`
+  - fragmentation via `from_bytes(..., max_fragment_bytes=...)`
+  - checksum validation over reconstructed tensor bytes
+  - unknown-field preservation via `extensions`
+- `ActivationEnvelope`
+  - top-level fields for `request_id`, `work_id`, `route_session`, `route_epoch`, `shard_start`, `effective_start`, `phase`, `position`, and `idempotency_step`
+  - reserved extension fields for `token_id_sideband`, `architecture_state`, `recurrent_state`, and `mtp`
+  - deterministic canonical serialization (`to_bytes`) and round-trip parsing (`from_bytes`)
+  - size-limit enforcement (`to_bytes(max_bytes=...)`)
+  - conversion from a live `TensorPayload` into the envelope and back again
+
+### `packages/node/meshnet_node/model_backend.py`
+
+Extended `TensorPayload` with envelope conversion helpers:
+
+- `TensorPayload.to_envelope(...)`
+- `TensorPayload.from_envelope(...)`
+
+These keep the existing activation payload interface intact while exposing the new versioned envelope as the shared protocol layer.
+
+### `tests/test_activation_envelope.py` (new)
+
+Added focused deterministic tests covering:
+
+- deterministic envelope serialization and round-trip parsing
+- tensor fragmentation and checksum validation
+- unknown-field preservation at both envelope and tensor levels
+- size-limit rejection
+- `TensorPayload` ↔ envelope round-trip
+
+### `.scratch/distributed-gguf-runtime/prd.json`
+
+Marked `DGR-021.passes = true` and added completion notes recording the envelope implementation and verification commands.

+
+## Limitations
+
+- The envelope is implemented as a canonical deterministic JSON contract with dataclasses and conversion hooks, not generated `.proto` classes. The environment had `protobuf` available but not the `grpc_tools` generation toolchain, so I did not materialize a compiled proto artifact here.
+- The direct/relayed HTTP/WebSocket transports remain byte-oriented; the envelope is the shared structured contract layered above those transports.
+
+## Dependency handoff
+
+DGR-022 and later shard-control stories can reuse the envelope contract and its `TensorPayload` conversion hooks as the stable activation metadata layer. Future work that requires generated protobuf code can replace the JSON serialization with a generated wire codec without changing the top-level field contract defined here.

+# DGR-022 evidence — Shard lifecycle and structured status RPC contract
+
+**Completed:** 2026-07-17
+**Branch:** `ralph/distributed-gguf-runtime`
+**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
+
+## Outcome
+
+Implemented the versioned, backend-neutral lifecycle/status contract consumed by a future generated gRPC binding. The contract keeps Meshnet routing, identity, authentication policy, billing, and llama.cpp ownership outside the worker contract.
+
+## Implemented
+
+- `packages/node/meshnet_node/shard_lifecycle.py`
+  - capability, health, session, cancellation, release, and metrics RPC names
+  - schema version negotiation and fail-closed unsupported-version handling
+  - structured status/error taxonomy with retryability and details
+  - lifecycle state machine for prefill/decode/cancel/release transitions
+  - monotonic idempotency-step enforcement and duplicate rejection
+  - bounded frame/byte flow control with cancellation-aware waits
+  - explicit cache expectation/result types
+  - deadline policy and TLS/auth transport hooks
+  - deterministic contract serialization round-trip
+- `tests/test_shard_lifecycle.py`
+  - contract round-trip and RPC coverage
+  - unsupported-version rejection
+  - malformed transition and idempotency rejection
+  - cancellation/release behavior
+  - bounded flow-control behavior
+  - TLS hook and incomplete-contract fail-closed behavior
+
+## Verification
+
+```text
+$ PYTHONPATH=packages/node pytest -q tests/test_shard_lifecycle.py tests/test_activation_envelope.py
+17 passed in 0.10s
+```
+
+The existing DGR-021 activation-envelope tests remain green alongside DGR-022.
+
+## Scope limitation
+
+This story defines the lifecycle/status contract only. Generated Python/C++ protobuf bindings and the concrete `shard_runtime.proto` generation pipeline are DGR-023 and remain separate.
+
+## Dependency handoff
+
+DGR-023 may consume the RPC names, status taxonomy, version identity, deadlines, flow-control limits, and TLS/auth hooks when the canonical `.proto` schema and toolchain are provisioned.

+# DGR-023 evidence — reproducible Python and C++ protobuf/gRPC generation
+
+**Status:** complete after controller verification and independent-review repairs on 2026-07-17.
+
+**Authority:** live Gitea issue #7. The local PRD is a secondary projection.
+
+## Implemented contract
+
+- Python generation requires exactly `grpcio-tools==1.82.1`; the generator checks installed distribution metadata and rejects missing or different versions with an actionable exact install command.
+- The C++ bootstrap builds one ignored toolchain prefix from exact inputs:
+  - Protobuf release `33.1` (`protobuf-config` version `33.1.0`);
+  - Abseil release `20250814.1`;
+  - gRPC C++ `1.82.1` at commit `acccf84c0df20487d64101f528e5d426541ca4e5`;
+  - gRPC's exact-commit submodules for c-ares, RE2, OpenSSL, and zlib.
+- Protobuf is configured with local dependencies only after the exact Abseil build. gRPC uses the installed Protobuf/Abseil packages and commit-pinned module dependencies, avoiding unpinned system development packages and download fallbacks.
+- CMake requires exact Protobuf `33.1.0` and gRPC `1.82.1`, requires the exported `gRPC::grpc_cpp_plugin` target, and always generates/builds both message and service stubs in the ignored build tree.
+- Python bindings remain committed package output; `--check` regenerates into a temporary directory and compares output. C++ bindings are never committed.
+- The C++ conformance test parses Python-produced vectors, validates fields/CRC32C, and emits `cpp_roundtrip.binpb`; Python compares that artifact byte-for-byte.
+
+## Defects found and fixed
+
+1. A relative bootstrap prefix was resolved after entering the temporary source directory, so successful output was deleted by cleanup. The script now canonicalizes the caller-relative destination first. The regression executes `--print-prefix` from a temporary working directory and validates the resulting path behavior.
+2. The original native path omitted gRPC C++ and accepted any discoverable plugin. The bootstrap now builds exact gRPC/plugin sources, and CMake rejects absent/incompatible versions.
+3. The Python script named the `grpcio-tools` pin but did not validate the installed distribution. It now refuses mismatched versions.
+4. Protobuf ignored a stale provider option and attempted to download a different Abseil. The build was stopped; exact Abseil is now built first and Protobuf uses `LOCAL_DEPENDENCIES_ONLY`.
+5. The host lacked OpenSSL development headers. Rather than add a floating system dependency, gRPC now uses the submodule pinned by its exact commit.
+6. Documentation uses `bash scripts/bootstrap_native_toolchain.sh ...`, so a normal checkout does not depend on executable-mode preservation.

+# DGR-024 evidence — real generated-gRPC protocol harness
+
+**Status:** independently re-verified in a fresh worktree/environment (this session); `prd.json` `DGR-024.passes` is now `true`.
+**Authority:** live Gitea #8 (revised); the local PRD is a secondary projection.
+
+## Policy history
+
+An earlier iteration of this lane implemented `FakeShardSeam` /
+`InMemoryGrpcChannel`, an in-memory fake transport. A subsequent policy audit
+rejected that approach outright under the no-fake-data/no-demo-implementation
+rule (see `prd.json`, `DGR-024.notes`): "the former in-memory fake/stub seam
+task was invalid... Existing fake-seam work is preserved as unaccepted
+historical material and must not be integrated." That code
+(`fake_shard_seam.py`, `test_fake_shard_seam.py`) is **not present** in this
+worktree and must not be resurrected. This document supersedes any earlier
+evidence describing it.
+
+## Outcome
+
+A real `ShardRuntimeServicer` (`packages/node/meshnet_node/shard_runtime_server.py`)
+runs as an actual OS process, bound to a real localhost TCP socket, speaking
+the generated `shard_runtime_pb2`/`shard_runtime_pb2_grpc` stubs over real
+gRPC/HTTP2 — no in-memory channel, no synthetic model output. A test harness
+(`tests/test_shard_runtime_harness.py`) spawns that process with
+`subprocess.Popen`, waits for its real "listening on" readiness line, and
+drives it with a generated `ShardRuntimeStub` over `grpc.insecure_channel`.
+
+## Implemented
+
+- `GetCapability` / `Health` unary RPCs over the real socket.
+- `Session` bidirectional stream: `SessionOpen` handshake → `SessionAccepted`,
+  then `ActivationChunk` prefill and compact `DecodeStep` decode frames, each
+  echoed back after a real bounded forward (a CRC32C checksum derived from the
+  bytes actually deserialized off the socket — `derive_checksum`).
+- **Wire fidelity proof**: the harness performs a DIRECT localhost hop and then
+  an OPAQUE RELAY that re-sends the exact captured request bytes verbatim
+  (`identity_send=True`, no reinterpretation), and asserts the server's
+  responses are byte-identical between the two paths. A server-side
+  `WireCapture` independently persists the same request bytes to a JSON-lines
+  file, cross-checked against what the client believes it sent.
+- **Fail-closed negative paths** (`ShardRuntimeServicer.Session`, per-
+  `route_session_id` `SessionState`):
+  - Stale route epoch on an `ActivationChunk` → `ERROR_CODE_EPOCH_STALE`.
+  - Expired `deadline_unix_nanos` (chunk or decode) → `ERROR_CODE_DEADLINE_EXCEEDED`.
+  - Fragment tiling gap/overlap or CRC32C checksum mismatch on an uncompressed
+    tensor (`_validate_bundle`) → `ERROR_CODE_PAYLOAD_CORRUPT`.
+  - Exhausted flow-control credit → `ERROR_CODE_FLOW_CONTROL_VIOLATION`
+    (`retryable=True`); an in-band `FlowControl` top-up message tops the
+    session's remaining credit back up (capped at `max_inflight_chunks`).
+  - Duplicate `idempotency_step` → `Ack(duplicate=True)` instead of
+    re-executing the step.
+  - In-band `CancelSignal` with a `work_id` cancels only that item (session
+    continues, non-terminal `ShardStatus`); an empty `work_id` cancels the
+    whole session (terminal). The out-of-band unary `Cancel` RPC reaches the
+    same shared, lock-guarded `SessionState`, including a race where `Cancel`
+    arrives before the matching `SessionOpen` — the eventual session for that
+    id still fails closed.
+- `Release` and `Cancel` unary RPCs operate on real per-session state rather
+  than a hardcoded response (`released` reflects whether the session existed;
+  `cancelled_work_items` reflects whether cancellation was newly recorded).
+
+## Verification
+
+The previous evidence for this story predated an environment with `grpc`
+importable (`tests/test_shard_runtime_harness.py` could not even *collect* on
+the ambient interpreter — see `.ralph-tui/progress.md`'s DGR-019 entry). This
+session built a real, disposable `uv`-managed `.venv` at the repo root and
+installed only the protocol-relevant floors already pinned in
+`packages/node/pyproject.toml` (`grpcio==1.82.1`, `grpcio-tools==1.82.1`,
+`protobuf==7.35.1`) plus `pytest==9.1.1`, then reran the full harness for
+real — this is not a re-statement of the earlier claim, it is an independent
+execution:
+
+```bash
+uv pip install grpcio grpcio-tools==1.82.1 protobuf pytest
+PYTHONPATH=packages/node:packages/tracker .venv/bin/python -m pytest -q tests/test_shard_runtime_harness.py -v -s

+subprocess/socket/direct-vs-relay byte-identity proof, now extended with the

+idempotency step, flow-control violation + top-up, in-band cancel of one work
+item vs. the whole session, and an out-of-band `Cancel` RPC racing ahead of
+`SessionOpen`.
+
+### Wire-frame hashes (new this session)
+
+The prior evidence proved wire fidelity only by raw byte-equality assertions;
+it recorded no hash. `WireCapture.to_dict()`
+(`packages/node/meshnet_node/shard_runtime_server.py`) now also persists
+`requests_sha256`/`responses_sha256` — SHA-256 over the concatenation of the
+exact serialized frame bytes the server captured, independent of the client's
+own view. `tests/test_shard_runtime_harness.py::test_shard_runtime_real_subprocess_harness`
+asserts these server-persisted hashes equal independently-computed SHA-256
+hashes over the client-side captured bytes, and that the DIRECT and OPAQUE
+RELAY hashes are identical:
+
+```text
+wire-frame sha256: requests=0eeae5943363a7cb7b74f6d4d819254d841397bb89fc36639b79595ec799765e responses=beeb3408d5401e362b2ebd3b2b0f20fd17be94cd7ba587ad7f9deaa7060d8ab1

+branch merge commits.
+
+## Limitations and handoff
+
+- This is a model-free protocol/transport harness: `GetCapability` reports a
+  fixed test fingerprint, not a real validated model artifact, and the
+  "bounded real forward" is a checksum-and-echo, not real tensor compute.
+- Checksum/tiling enforcement only covers `CHECKSUM_ALGORITHM_CRC32C` +
+  `COMPRESSION_NONE` tensors; a compressed tensor's fragment tiling is not
+  independently re-verified here (would require a real zstd decompressor).
+- Flow control is a simple per-session credit counter, not a full HTTP/2-aware
+  admission model; it demonstrates the required violate/top-up/recover cycle
+  but does not enforce `max_chunk_bytes`/`max_prefill_chunk_tokens` size
+  limits yet — a real worker (DGR-029+) should add those checks.
+- `CacheExpectation`/`CacheResult`/`CACHE_MISS` handling is not exercised: the
+  echo server has no real KV/session cache to miss against. A real worker
+  implementation owns that.
+- Session state lives in process memory for the life of the server process;
+  there is no persistence or multi-process sharing story, which is fine for a
+  single-worker protocol harness but not for a production worker.

+# DGR-025 evidence — exact artifact and runtime recipe identity
+
+**Status:** in progress — controller gates pass; final independent P0/P1 re-review is pending.
+**Branch:** fixed detached Claude Fable provider lane
+**Authority:** live Gitea #9; the local PRD is a secondary projection.
+**Dependencies:** DGR-018 (`evidence/DGR-018/README.md` — canonical backlog schema and
+issue projection), DGR-021 (`evidence/DGR-021/README.md` — versioned activation
+envelope). Both read before changing code.
+
+## Objective
+
+Ensure the tracker and worker only combine numerically and operationally
+compatible shards: fingerprint every axis that moves the numbers, bind shards to
+exact half-open ranges, fail closed on any mismatch, and keep uncertified
+recipes registered-but-dark.
+
+## What was found live (verified, not inherited)
+
+Per RALPH-CONTEXT, legacy pass states were not trusted. The DGR-003-lineage
+identity core was inspected and exercised live before any change:
+
+- `packages/node/meshnet_node/runtime_recipe.py` — node-side identity:
+  domain-separated digests (`meshnet.model-artifact.v1`,
+  `meshnet.runtime-recipe.v1`, `meshnet.shard-binding.v1`) over the source
+  artifact SHA (`source_digest`, with split artifacts bound to their exact
+  source via `DerivativeBinding`), tokenizer revision (pin-enforced),
+  architecture adapter + architecture/config digest, boundary and protocol
+  schema versions, backend, weight quantization, activation/compute dtypes, and
+  KV dtype/layout (`RECIPE_AXES`). Shard ranges are half-open
+  (`shard_start`/`shard_end`, end-exclusive, protocol convention) with no
+  topology or quant constants anywhere; `check_route` accepts any tiling of
+  `[0, layer_count)`. Route, handshake (`check_handshake`), and session-open
+  (`check_session_open`) checks fail closed with structured `RouteMismatch`
+  reasons mapped to specific protocol error codes (`handshake_error`).
+- `packages/tracker/meshnet_tracker/recipe.py` — deliberately independent
+  tracker re-derivation (no `meshnet_node` import); declared fingerprints are
+  recomputed, never trusted (`parse_identity`, `FingerprintMismatch`). The
+  `CertificationLedger` keeps every registered recipe dark until a real
+  distributed forward — at least 2 distinct nodes, whole-model coverage,
+  non-synthetic, tokens actually generated — certifies it; dark recipes may
+  route only to certify.
+- The two implementations are pinned by committed conformance vectors
+  (`tests/data/recipe_fingerprint_vectors.json`).
+
+Live verification of that pre-existing core before changes:
+`PYTHONPATH=packages/node:packages/tracker python3 -m pytest -q tests/test_runtime_recipe_identity.py`
+→ `45 passed`; plus `tests/test_native_identity_emission.py`,
+`tests/test_tracker_capability_admission.py`, `tests/test_node_admission.py`
+→ `59 passed`.
+
+## Gap found and closed (this story's change)
+
+**The `runtime_version` recipe axis was a label, not a pin.** It was an opaque
+caller-supplied string: nothing derived it from the DGR-027 lock manifest, and
+neither identity implementation rejected a moving reference (`"latest"` was
+accepted), so two workers could run different llama.cpp pins or patch stacks
+under one label and still agree on the recipe digest. The acceptance criterion
+explicitly requires fingerprinting the "runtime pin/patch stack".
+
+### Changed files
+
+- `packages/node/meshnet_node/runtime_pin.py` (new) — derives the canonical
+  `runtime_version` axis value from the DGR-027 lock workspace
+  (`packages/node/native/llama`):
+  `<runtime>@<40-hex upstream commit>+patchstack.<sha256>` where the stack
+  digest commits, under the `meshnet.runtime-patch-stack.v1` domain, to the
+  *ordered* `(patch name, patch bytes sha256)` stack. Fails closed on: missing
+  or malformed `UPSTREAM_LOCK.json`, unknown schema version, non-40-hex/moving
+  commit, `UPSTREAM_COMMIT` disagreement, any disagreement among the lock's
+  `patch_series`, `patches/series`, and `patches/SHA256SUMS`, a missing patch
+  file, or a patch whose bytes don't match their recorded digest. Reads the
+  committed manifest only; fetching/patching stays with
+  `scripts/llama_cpp_dependency.py` (DGR-027).
+- `packages/node/meshnet_node/runtime_recipe.py` — `runtime_version` is now
+  pin-enforced (`_require_pin`) exactly like `tokenizer_revision`; for the
+  llama.cpp backend it must also match the canonical
+  `llama.cpp@<40-hex>+patchstack.<64-hex>` grammar.
+- `packages/node/meshnet_node/native_backend.py` — the production native
+  identity seam no longer accepts a caller-supplied runtime string. It derives
+  `runtime_version` directly through `load_runtime_pin()` from the committed
+  lock and rejects a non-llama backend at this llama.cpp-specific boundary.
+- `packages/tracker/meshnet_tracker/recipe.py` — the independent tracker
+  implementation applies the same backend-specific grammar before re-deriving
+  the recipe digest, so forged operator labels cannot register or certify.
+- `tests/test_runtime_pin_identity.py` and
+  `tests/test_native_identity_emission.py` — deterministic tests cover lock
+  derivation, production native emission, and node/tracker rejection of the
+  forged values from independent review. Conformance vectors were regenerated
+  through `scripts/gen_recipe_fingerprint_vectors.py` for the tightened wire
+  contract.
+
+### Backlog-consistency repair (pre-existing damage, honestly recorded)
+
+`tests/test_ralph_prd_schema.py` had 4 pre-existing failures before this story
+touched anything, left by prior sessions and the alternate-history merge:
+
+- DGR-022 and DGR-027 were marked `passes: true` without `completionNotes` and
+  without regenerated issue projections. Added their `completionNotes`
+  (explicitly labeled as added during this repair, content drawn from their own
+  evidence READMEs) and regenerated
+  `issues/022-…` / `issues/027-…` via `scripts/ralph_prd_schema.py render`.
+- Three pre-DGR legacy GLM alpha issue files (`18-…`, `19-…`, `20-…`,
+  committed 2026-07-14, before DGR-018 established the generated-only
+  convention; they carry no authority disclaimer because they are *not*
+  generated from prd.json) were relocated via `git mv` to
+  `issues/legacy/` — preserved as provenance, out of the generated namespace.
+
+### prd.json
+
+Marked `DGR-025.passes = true` with `completionNotes`; regenerated
+`issues/025-define-exact-artifact-and-runtime-recipe-identity.md`.
+
+## Acceptance criteria → evidence
+
+1. **Fingerprint all axes** — `RECIPE_AXES` + `ArtifactIdentity` cover source
+   artifact SHA, tokenizer revision, architecture adapter/version (adapter axis
+   + architecture/config digest), boundary schema (boundary + protocol schema
+   versions), backend, quant, activation/compute dtype, KV/state layout; the
+   runtime pin/patch stack is now committed via the derived `runtime_version`
+   axis (`runtime_pin.py`). Verified by `test_runtime_recipe_identity.py` and
+   `test_runtime_pin_identity.py`.
+2. **Exact half-open range, no hardcoded topology/quant** — `ShardIdentity`
+   end-exclusive ranges, `DerivativeBinding` coverage checks, `check_route`
+   tiling over arbitrary layouts; quant/dtype values are open strings
+   (dynamic recipe inputs). Verified by `test_runtime_recipe_identity.py`
+   (routes of 1, 2, and 5 shards; no product constants).
+3. **Fail closed on any mismatch** — artifact, adapter, boundary/schema, cache
+   layout, backend, and runtime mismatches each produce structured
+   `RouteMismatch` reasons and protocol error codes; the tracker recomputes
+   digests and rejects inconsistent claims; moving runtime references are now
+   rejected on both sides.
+4. **Registered-but-dark** — `CertificationLedger`: unknown recipes cannot be
+   certified, registered recipes are dark, only a real ≥2-distinct-node
+   whole-model non-synthetic forward promotes; verified by
+   `test_runtime_recipe_identity.py` / `test_tracker_capability_admission.py`.
+5. **Gates + this handoff** — below.

+## Limitations
+
+- The production native identity seam now derives the manifest pin and cannot
+  accept an operator-supplied runtime label. It still cannot attest that the
+  running binary was built from those locked bytes. Embedding the patched-tree
+  hash at build time and echoing it through the DGR-022 status contract belongs
+  with DGR-028+/DGR-031; real distributed certification remains the final trust
+  boundary.
+- The DGR-027-recorded blocker stands: `0002-dense-llama-owned-range-loader.patch`
+  does not apply cleanly against the pin (DGR-028). That does not affect this
+  story: the identity commits to the patch *bytes as committed*, which is
+  precisely what makes a later repaired patch a *different* runtime identity.
+- No native/CMake change was made, so the native build/CTest gate is not
+  applicable; no llama.cpp patch content was changed, so apply/check/reverse
+  verification is not applicable (and is blocked by the DGR-028 defect anyway).
+- Tracker routing, load balancing, billing, telemetry, and relay semantics are
+  untouched; the only behavior change outside the new module is the stricter
+  (fail-closed) rejection of moving `runtime_version` values.
+
+## Dependency handoff
+
+- **DGR-026** (split-GGUF provisioning): bind each provisioned split via
+  `DerivativeBinding` to the exact source digest recorded in its hashed
+  manifest; the per-split `shard_binding_digest` is what certification pins.
+- **DGR-031** (`ShardEngine`): construct worker identity through
+  `shard_identity_from_native_report` and populate `runtime_version` from
+  `meshnet_node.runtime_pin.load_runtime_pin().runtime_version` — never from an
+  operator string. A build-time echo of the patched-tree hash through the
+  status contract would close the manifest-vs-binary gap noted above.
+- **DGR-041** (capability registration): the tracker already re-derives and
+  fail-closes on presented identities (`parse_identity`); register recipes
+  through the `CertificationLedger` so they arrive dark.
+- **DGR-044** (DeepSeek V4 Flash target): pin the target's artifact identity
+  the same way `glm_alpha_artifact` does — read locked manifests, never restate
+  digests — and note `layer_count` must count the routed transformer stack the
+  route tiles, excluding MTP (reserved for beta).
+
+## Reopened P1 repair — 2026-07-18
+
+The earlier evidence above is provenance only. Its stated limitation — that
+the identity seam could not attest the executing runtime — was reproduced in
+late review, along with the tokenizer-label weakness. This repair replaces
+both claims at the production identity boundary.
+
+### Changed files
+
+- `packages/node/meshnet_node/runtime_recipe.py` — replaces the moving-ref
+  denylist with the sole valid `tokenizer.v1:<sha256>` form, derived from an
+  ordered map of named tokenizer/config byte digests. A label, tag, branch, or
+  symbolic ref cannot be a valid identity.
+- `packages/tracker/meshnet_tracker/recipe.py` — independent tracker
+  derivation and validation of the same tokenizer byte identity; it does not
+  import node code.
+- `packages/node/meshnet_node/runtime_pin.py` — adds patched source-tree and
+  numerically relevant build-recipe digest to the lock-derived runtime pin.
+- `packages/node/meshnet_node/native_backend.py` —
+  `NativeLoadedArtifactReport` now requires an executing-runtime attestation:
+  runtime/source-tree/patch-stack/build-recipe digests and boundary/protocol
+  ABI versions. `shard_identity_from_native_report` compares every field to
+  the lock/build-derived expectation before emitting an identity.
+- `scripts/gen_recipe_fingerprint_vectors.py` and
+  `tests/data/recipe_fingerprint_vectors.json` — regenerate canonical vectors
+  for the strengthened wire contract.
+- `tests/test_runtime_pin_identity.py`,
+  `tests/test_runtime_recipe_identity.py`, and
+  `tests/test_native_identity_emission.py` — cover mutable labels including
+  `origin/main`, `stable`, `release`, a tag, and `HEAD`; independent node and
+  tracker validation; distinct byte sets under one label; one-byte fingerprint
+  change; build-recipe change; and each executing-runtime attestation mismatch.

+this sandbox (`PermissionError: [Errno 1] Operation not permitted` creating an
+AF_INET socket); its deterministic non-socket identity coverage is included in
+the passing runs above.
+
+### Remaining boundary (superseded 2026-07-18, same day — see below)
+
+The attestation at this point was a native runtime report *contract*: a
+Python dataclass the worker was trusted to populate. Late review reproduced
+the obvious hole — `load_runtime_pin()` is world-readable, so any operator
+could copy the lock's values into the dataclass and pass every comparison.
+The section below closes that hole.
+
+## Executing-artifact evidence binding — 2026-07-18 (this repair)
+
+The executing native runtime's identity must not be forgeable by copying
+repository lock values into a Python self-report. Attestation values are now
+accepted only when *extracted from the native artifact itself*, through two
+channels that must agree, and the seam fails closed until such native
+evidence exists.
+
+### The boundary
+
+`meshnet_node.native_backend` now defines the attestation extraction
+contract:
+
+- **Static channel** — the artifact's bytes must embed exactly one
+  NUL-terminated `MESHNET-RUNTIME-ATTESTATION.v1:<canonical json>` marker.
+  The canonical payload (`attestation_payload` /
+  `expected_attestation_payload`) commits to runtime name, upstream commit,
+  patched tree, ordered patch-stack digest, build-recipe digest, and
+  boundary/protocol ABI versions; the DGR-027 CMake ABI-marker lane is where
+  a real native build bakes it in from the lock at configure time.
+- **Dynamic channel** — the artifact must actually `dlopen`, and its exported
+  `llama_meshnet_runtime_attestation` symbol must return byte-identically the
+  embedded marker. A marker pasted into a plain file is not an executing
+  runtime.
+- **Evidence capability** — `attest_loaded_runtime(artifact_path)` is the
+  only mint for `NativeArtifactEvidence` (module-private token). The evidence
+  records the artifact path, a sha256 over the artifact bytes
+  (`binary_digest`), and a sha256 over the extracted payload
+  (`payload_digest`). `NativeRuntimeAttestation` requires the evidence and
+  re-derives the canonical payload from its own field values on
+  construction: if the digest disagrees, construction fails — so
+  `dataclasses.replace`-style laundering of a mismatched runtime with copied
+  lock values also fails.
+- `shard_identity_from_native_report` is unchanged downstream: it still
+  compares every attested field to the lock/build-derived expectation and
+  the `runtime_version` axis stays lock-derived, so the committed
+  conformance vectors are unchanged by this repair (regenerated and
+  byte-stable).
+
+Fail-closed consequence: in a workspace with no built native artifact (this
+one — the DGR-028 patch defect still blocks a native build), no attestation
+and therefore no native identity can exist at all.
+
+### Changed files
+
+- `packages/node/meshnet_node/native_backend.py` — marker/symbol contract,
+  canonical payload encoding, `NativeArtifactEvidence` (token-guarded),
+  evidence-bound `NativeRuntimeAttestation`, `attest_loaded_runtime`
+  extractor with strict payload parsing (exact key set, types, canonical
+  re-encoding).
+- `tests/test_native_identity_emission.py` — rewritten around real compiled
+  fixture artifacts: tests build tiny genuine/forged shared objects with
+  `cc -shared` at test time (skipped cleanly if no C compiler; one is
+  present here) and prove copied lock values alone cannot pass anywhere.
+
+### Behavior tests proving copied lock values cannot pass
+
+- Bare `NativeRuntimeAttestation(**lock_values)` (the pre-repair forgery) is
+  unconstructible; `evidence=None` and hand-authored/`object()`-token
+  `NativeArtifactEvidence` each raise.
+- The true marker bytes written into a plain file fail (`not a loadable`).
+- A loadable artifact with no marker, with conflicting markers, without the
+  exported symbol, whose symbol disagrees with its marker, or whose payload
+  is non-canonical (wrong keys, or right keys re-encoded with whitespace)
+  each fail closed.
+- A self-consistent artifact built from the *wrong* values attests, then
+  fails identity emission per-field (runtime name, upstream commit, patched
+  tree, patch stack, build recipe, boundary/protocol ABI), and
+  `dataclasses.replace`-ing it with the lock's true values fails the
+  evidence binding (`edited after extraction`).
+- The genuine path: an artifact embedding
+  `expected_attestation_payload(load_runtime_pin())` attests, emits the
+  lock-derived identity, and its evidence `binary_digest` equals the sha256
+  of the artifact bytes.

+
+A controller full-suite run (`python3 -m pytest -q`) was also executed and is
+not represented as green: `13 failed, 1104 passed, 22 skipped, 2 warnings`.
+The failures are outside the DGR-025 changed paths: unavailable optional
+`zstandard`/`langchain_openai` dependencies, unrelated billing/dynamic-routing/
+tracker expectations, and the already recorded stale DGR-023 local projection.
+The exact DGR-025 identity suites and broader admission coverage remain green as
+recorded above.
+
+### Remaining boundary
+
+What is now proven: no identity can be constructed, registered, admitted, or
+certified without evidence extracted from an actual loadable native artifact
+that both embeds and reports the attestation, and the extracted values cannot
+be edited afterward. What is deliberately not claimed: a cross-compiler
+bit-reproducible binary SHA, defense against an adversary who *builds* a
+native artifact that embeds lock-true values while lying about its source
+(a categorically higher bar than authoring a Python dict), an OS-level swap
+of the artifact file between the byte read and the `dlopen` (documented
+residual race), or in-process tampering below Python semantics. Real
+distributed certification (the registered-but-dark ledger) remains the final
+backstop behind this boundary; the DGR-028+ native build lane must embed the
+marker via the reserved CMake ABI-marker hook.
+
+## Executing-byte identity repair — 2026-07-18 controller follow-up
+
+A later controller review rejected the preceding remaining-boundary claim as
+insufficient for DGR-025: a separately built loadable shared object could copy
+all public lock values into both marker channels and receive the same
+`runtime_version` as a certified artifact. The repair now appends
+`+artifact.<sha256>` to the llama.cpp runtime axis, where the digest is computed
+from the exact bytes read by `attest_loaded_runtime`. Node and tracker parsers
+independently require this suffix. Consequently, copying lock values into a
+different loadable artifact produces a different recipe fingerprint; only the
+same artifact bytes can retain the same identity, and every new binary remains
+dark until certified.
+
+`test_copying_public_lock_values_cannot_forge_the_certified_runtime_identity`
+builds a second loadable artifact with byte-identical lock attestation but
+different executable bytes, and proves both its `runtime_version` and recipe
+digest differ from the accepted artifact. Conformance vectors were regenerated
+for the strengthened wire identity.

+# DGR-026 evidence — provision exact split-GGUF artifacts outside `/home`
+
+**Status:** implemented and verified this session; live re-review, not inherited credit.
+**Dependency:** DGR-025 (`evidence/DGR-025/README.md`) — read before changing code.
+
+## Objective
+
+Make exact split-GGUF inputs reproducibly available from mounted-drive
+storage, bound by a hashed manifest that fingerprints the source artifact,
+tokenizer/revision, and every split file, without embedding a quantization or
+split-topology assumption anywhere in product code.
+
+## What was found live (verified, not inherited)
+
+Per RALPH-CONTEXT, legacy pass states were not trusted. No prior split-GGUF
+manifest or provisioning module existed:
+`grep -rln "provision\|mounted-drive" packages/ scripts/ tests/` found only
+`packages/node/meshnet_node/recipe_drivers.py`'s existing
+`artifact_storage_root` `/home` check (benchmark config validation, not
+provisioning) and the RALPH-CONTEXT/prd.json prose itself. The pre-existing
+`packages/node/meshnet_node/downloader.py` is a different mechanism entirely —
+it fetches HuggingFace SafeTensors *layer* shards into `~/.cache/meshnet/shards`
+(i.e. under `/home` by default) for the existing Tracker route/download flow,
+with no manifest binding or split-GGUF concept; it was left untouched because
+this story's provisioning target (mounted-drive-only, hash-manifest-bound
+split-GGUF files) is a distinct concern from that peer/HF shard cache.
+
+Two existing conventions were read and reused directly rather than
+reinvented:
+
+- `packages/node/meshnet_node/glm_alpha/manifest.py` (DGR-017) — the
+  per-shard identity manifest shape (name/size/sha256/revision, aggregate byte
+  cross-check) that this story's manifest schema follows for source/split
+  records.
+- `packages/node/meshnet_node/runtime_recipe.py`'s `DerivativeBinding` (DGR-003)
+  — the half-open (`shard_start`, end-exclusive `shard_end`) range convention
+  a split is bound to its source under; this story's optional per-split range
+  fields use the same convention so a route already speaks the same layout
+  language.
+- `packages/node/meshnet_node/recipe_drivers.py`'s `_validate_config` — the
+  exact `/home` rejection shape (`not root.is_absolute() or root ==
+  Path("/home") or Path("/home") in root.parents`) this story's
+  `reject_home_path` mirrors for provisioning destinations.
+
+## What was built (this story's change)
+
+### `packages/node/meshnet_node/split_gguf/` (new package)
+
+- **`manifest.py`** — `SplitArtifactManifest`: binds a `SourceArtifact`
+  (artifact id, repo, 40-hex pinned revision, sha256, size), a `TokenizerRef`
+  (repo, 40-hex pinned revision, sha256), a free-form `quantization` string
+  (a recipe input, not a validated enum), and a tuple of `SplitFile` records —
+  each with `name`, `size_bytes`, `sha256`, `role`, optional `url`, and an
+  optional half-open (`shard_start`, `shard_end`) range. `total_bytes` is
+  cross-checked against the sum of split sizes (rejects a hand-edited "it fits
+  now" manifest, mirroring DGR-017's aggregate check); duplicate names and
+  duplicate content hashes are rejected; revisions must be full 40-hex commits
+  (a branch/tag/short-SHA is refused). Nothing in this module names a
+  quantization, shard count, or layout — `test_quantization_and_topology_are_manifest_data_not_constants`
+  parses a single-split, differently-quantized manifest to prove it.
+- **`provision.py`** — `provision_split_artifact(manifest, dest_dir, fetch)`:
+  for each split, reuses an already-correct final file untouched (idempotent
+  re-run), discards and re-fetches a file with the wrong size/hash rather than
+  trusting it, stages fetches as `<name>.partial` so an interrupted run
+  resumes from the exact byte offset already on disk (a stale partial *larger*
+  than the manifest size is discarded and restarted, never trusted), and
+  promotes a partial to its final name only once its SHA-256 matches the
+  manifest exactly — a short, truncated, or hash-mismatched split is deleted
+  and raises `SplitProvisionError` rather than being silently accepted.
+  `verify_provisioned_split_artifact` is the standalone completeness/hash
+  check a downstream loader or a resumed run should call before trusting a
+  directory. `reject_home_path` is the fail-closed `/home` gate, called by
+  every entry point (provision, verify) before touching disk, and does not
+  require the destination to exist yet (provisioning creates it), unlike
+  `recipe_drivers.py`'s `strict=True` benchmark-root check. Two `SplitFetcher`
+  implementations are provided: `local_directory_fetcher` (byte-for-byte copy
+  with seek-based resume from a local directory — used by tests and for
+  splits already staged/mirrored on another local or mounted path) and
+  `http_split_fetcher` (Range-header resume over HTTP/HTTPS for real network
+  provisioning, with a fallback to a full restart if a server ignores
+  `Range`).
+
+### `scripts/provision_split_gguf.py` (new)
+
+A CLI wrapper: `--manifest`, `--dest`, optional `--source-dir` (uses
+`local_directory_fetcher` instead of downloading each split's manifest `url`).
+Manually smoke-tested end to end this session (see Commands below), including
+a real `/home` destination rejection through the CLI, not just the library.
+
+### Tests (new, deterministic, offline, GPU-free, download-free)
+
+- `tests/test_split_gguf_manifest.py` (19 tests) — resolves source/tokenizer/
+  splits correctly; quantization/topology are manifest data, not constants
+  (single-split, differently-quantized manifest parses); digest stability;
+  rejects: split declaring only one of `shard_start`/`shard_end`, an empty
+  range, a missing required field, a duplicate split name, two splits sharing
+  one content hash, an inconsistent aggregate byte total, a shrunk split size,
+  a truncated SHA-256, a branch-name source/tokenizer revision, an unsupported
+  schema version, an empty `splits` array.
+- `tests/test_split_gguf_provision.py` (12 tests) — covers exactly the four
+  scenarios the acceptance criteria name:
+  - **`/home` rejection** — a `/home/...` destination, `/home` itself, and a
+    nested `/home` subdirectory are refused by both `provision_split_artifact`
+    and `verify_provisioned_split_artifact`; a mounted-drive-style path is
+    accepted.
+  - **Interrupted download → resume** —
+    `test_an_interrupted_partial_download_resumes_from_its_exact_byte_offset`
+    plants a half-written `.partial` file, wraps the fetcher to record the
+    `resume_from_bytes` argument it's actually called with, and asserts
+    resume starts from the exact prior byte count (not 0) while an
+    unstarted split still starts from 0; a stale partial larger than the
+    manifest size is discarded and restarted from scratch.
+  - **Missing split** — a missing local source file raises
+    `SplitProvisionError` during provisioning; a split absent from an
+    already-provisioned destination is caught by
+    `verify_provisioned_split_artifact`.
+  - **Hash mismatch** — a same-size-but-wrong-content source file is rejected
+    (`SplitProvisionError`, and neither the corrupt final file nor its
+    `.partial` is left on disk); a destination file with the wrong hash (but
+    right size) is not trusted and is transparently replaced by a correct
+    re-fetch; a destination corrupted after a prior successful provisioning
+    run is caught by `verify_provisioned_split_artifact`.
+  - Also: idempotent no-op re-run over already-complete, correctly-hashed
+    splits (verified with the source files deleted, proving no re-fetch was
+    attempted).
+
+## Acceptance criteria → evidence
+
+1. **Exact manifest binding source artifact, tokenizer/revision, every split's
+   name/size/range-or-role/hash** — `SplitArtifactManifest`/`SourceArtifact`/
+   `TokenizerRef`/`SplitFile` in `manifest.py`; covered by
+   `test_split_gguf_manifest.py`.
+2. **Resumable, hash-verifying provisioning targeting mounted-drive storage;
+   refuses `/home` and incomplete/mismatched splits** —
+   `provision_split_artifact`/`verify_provisioned_split_artifact`/
+   `reject_home_path` in `provision.py`; covered by
+   `test_split_gguf_provision.py` and the CLI smoke test below.
+3. **Quantization/topology are manifest/recipe inputs, not hardcoded** —
+   `quantization` is a free-form string; `SplitFile.shard_start`/`shard_end`
+   are optional per-split fields; no product module names a quant, node
+   count, or range constant. Verified by
+   `test_quantization_and_topology_are_manifest_data_not_constants` (a
+   single-split, differently-quantized manifest parses without any code
+   change).
+4. **Deterministic model-download-free tests covering interrupted resume,
+   missing split, hash mismatch, `/home` rejection** — see the Tests section
+   above; all fixtures are in-memory or tiny `tmp_path` files, no network
+   access anywhere in the suite.
+5. **Gates + this handoff** — below.

+
+Before touching anything, `.scratch/distributed-gguf-runtime/prd.json`'s
+top-level `sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/
+`supersededStories`/`branchName` fields were already missing in the working
+tree at session start (this is the fourth documented occurrence of the
+round-trip-drop bug noted in DGR-018/019/020/025's evidence — `userStories`
+itself was unaffected, only these top-level fields). Restored them from
+`git show HEAD:.scratch/distributed-gguf-runtime/prd.json` before making any
+DGR-026 edit; `scripts/ralph_prd_schema.py validate` reported `OK` both before
+and after the restoration, confirming (again) that this validator does not
+catch the drop on its own.
+
+## Limitations
+
+- `http_split_fetcher` (the real network-download path) is exercised only by
+  manual code review and the CLI's argument wiring, not by an automated test —
+  by design, since the default suite must stay network-free. Its Range-header
+  resume logic shares the same `provision_split_artifact` byte/hash
+  verification as the tested `local_directory_fetcher` path, so the
+  fetcher-specific risk surface is the HTTP interaction itself (server Range
+  support, redirects, auth), not the resume/verify contract.
+- No real DeepSeek V4 Flash split-GGUF manifest exists yet — this story
+  defines the manifest schema and provisioning tooling; DGR-044/DGR-045
+  (below) are what will populate a real manifest against the pinned target.
+- `python3 -m pytest -q` (unscoped full-repo sweep) was not run this session;
+  DGR-019/DGR-020/DGR-025's evidence already recorded several pre-existing,
+  unrelated failures in that sweep (missing optional `zstandard`/
+  `langchain_openai` dependencies, unrelated billing/dynamic-routing/cache
+  tests, and `tests/test_shard_runtime_harness.py`'s `grpc` import
+  requirement). This story's own targeted suites, `test_ralph_prd_schema.py`,
+  `compileall`, and `git diff --check` are all green as recorded above.
+- Tracker routing, load balancing, billing, telemetry, and relay semantics are
+  untouched; this story adds a new, isolated package and does not modify any
+  existing runtime/identity module.
+
+## Dependency handoff
+
+- **DGR-044** (DeepSeek V4 Flash target contract): when pinning the real
+  target's split-GGUF artifact, express it as a
+  `meshnet_node.split_gguf.manifest.SplitArtifactManifest` — `source.sha256`
+  is the whole-model artifact digest DGR-003's `ArtifactIdentity.source_digest`
+  compares against, and each `SplitFile`'s `shard_start`/`shard_end` should
+  match the exact ranges the route's `ShardIdentity`s claim.
+- **DGR-045** (V4 GGUF tensor/layer-ownership inventory): once layer ownership
+  per split is derived, populate each `SplitFile.role` and
+  `shard_start`/`shard_end` from that inventory rather than restating them —
+  this manifest is meant to bind, not redefine, DGR-045's ownership finding.
+- Any future story that actually provisions a real split-GGUF artifact onto
+  mounted-drive storage should call `provision_split_artifact` with
+  `http_split_fetcher` (or `local_directory_fetcher` if mirroring from another
+  local/mounted path) and must call `verify_provisioned_split_artifact` before
+  trusting a directory a prior run may have left partially populated.

+**Branch:** `ralph/dgr-small-terra`  
+**Authority:** live Gitea issue #11. The controller fetched and claimed the issue

+## Provenance and retrieval contract
+
+`UPSTREAM_LOCK.json` records the upstream Git URL, immutable 40-character
+commit `e920c523e3b8a0163fe498af5bf90df35ff51d25`, expected Git tree
+`6c91a11407a3a3fb160f5dac705f9c59718f54f1`, MIT license, and the sole
+retrieval method: `git-clone-detached-commit` into `build/llama.cpp/source`.
+
+`python3 scripts/llama_cpp_dependency.py fetch` has no branch, tag, ref, or
+repository override. On a first fetch it clones the manifest URL, checks out
+the detached commit, and verifies commit, tree, required upstream blobs,
+license, and cleanliness. If the workspace already exists, it makes no network
+request and accepts it only after the same verification. Dirty or mismatched
+caches fail closed. The build directory is already ignored by `.gitignore`.
+
+## Verification
+
+| Command | Result |
+| --- | --- |
+| `python3 -m pytest -q tests/test_llama_cpp_dependency.py` | `7 passed in 0.22s` |
+| `python3 -m compileall packages tests` | passed |
+| `git diff --check` | passed (no output) |
+| `python3 scripts/llama_cpp_dependency.py inspect` | passed; reports exact commit/tree, retrieval workspace, MIT license, and two-patch stack |
+| `python3 scripts/llama_cpp_dependency.py fetch --workspace /tmp/not-llama-workspace` | failed closed with status 2: workspace outside the locked ignored build root |
+| symlinked workspace regression | passed; both a `build/` ancestor symlink and a final `source` symlink escaping the repository are refused |
+| attached-branch cache regression | passed; an exact commit on a local branch is refused until checked out as detached HEAD |
+| ignored/excluded injection regression | passed; a file hidden by `.git/info/exclude` is detected and refused |
+| tracked injection regression | passed; modified tracked content hidden by both `assume-unchanged` and `skip-worktree` is content-hashed and refused |
+| executable-mode regression | passed on the POSIX fixture for both index flags; the mounted project workspace has `core.filemode=false`, so its exact index tree is the canonical mode record and physical mode bits are not treated as meaningful |
+| `git check-ignore -v build/llama.cpp/source` | passed; `.gitignore:6:build/` |
+| `git diff --summary` and `git ls-files build packages/node/native/llama` | no source checkout or new submodule introduced; only manifest/docs/patches/native wrapper are tracked |
+| `python3 scripts/llama_cpp_dependency.py fetch` (controller network lane) | passed; fetched the exact detached commit and verified HEAD `e920c523e3b8a0163fe498af5bf90df35ff51d25` and tree `6c91a11407a3a3fb160f5dac705f9c59718f54f1` in the ignored workspace |
+| `python3 scripts/llama_cpp_dependency.py apply --source-dir build/llama.cpp/source` | failed on the pre-existing `0002-dense-llama-owned-range-loader.patch` as a corrupt patch at line 26; this is an explicit DGR-028 blocker and no native-build claim is made |
+
+The targeted test suite creates a local Git fixture to prove offline cache reuse
+after full identity verification, then proves a dirty cache is rejected. It
+also proves the CLI rejects a repository/branch override and an arbitrary
+workspace.
+
+## Limitations
+
+- The controller successfully materialized and verified the exact upstream
+  commit/tree, so the DGR-027 fetch and offline-cache boundary has real upstream
+  evidence rather than fixture-only evidence.
+- The existing `0002-dense-llama-owned-range-loader.patch` is malformed and
+  cannot pass `git apply --check` against the exact pin. DGR-027 changes no patch
+  file; repairing and certifying the numbered patch stack belongs to DGR-028.
+  Until that story closes, the repository must not claim patched-tree, native
+  CMake/CTest, or reverse-apply certification.
+- No model, API credits, GPU, or model artifact storage was used.
+
+## Dependency handoff
+
+DGR-028, DGR-029, and DGR-044 must invoke the manifest-owned `fetch` command
+before touching llama.cpp source. They may use only the verified
+`build/llama.cpp/source` checkout and must record any native build, CTest, and
+patch apply/check/reverse evidence against the exact manifest pin. DGR-017's
+cleanup remains provenance only and grants no inherited completion credit.

+# DGR-028 evidence — numbered llama.cpp patch-stack verification
+
+**Status:** implementation complete; independently re-verified in a fresh Ralph session (2026-07-22) against live source and the real cached upstream checkout, per `RALPH-CONTEXT.md`'s "inspect live source/tests rather than trusting legacy pass states" mandate. `prd.json`'s `DGR-028.passes` is now `true`.
+**Authority:** local `prd.json` is authoritative; live Gitea #12 is a projection.
+**Upstream pin:** `e920c523e3b8a0163fe498af5bf90df35ff51d25` (`llama.cpp`)
+
+## Implemented
+
+- Replaced the stale non-applying range-loader patch with an ordered five-patch stack whose concerns are separated into build marker, dense-Llama owned-range loading, filtered state reporting, boundary I/O fail-closed guard, and worker range-report hook plus native fixture.
+- Added `patches/UPSTREAM-ASSUMPTIONS.json`, binding each patch to the exact pre/post blob IDs and named upstream API assumptions for every touched file.
+- Extended `scripts/llama_cpp_dependency.py` so `apply`, `reverse`, and `verify` validate patch digests, exact ordered coverage, assumptions, first-incompatible-patch behavior, pristine/patched Git trees, touched paths, license/attribution preservation, and exclusion of Meshnet control-plane concerns.
+- `verify` performs the complete apply/check/reverse cycle and leaves the cached detached upstream checkout pristine.
+- Updated the lock's exact patched tree and patch checksums. No model artifact was downloaded or created.
+
+## Controller repairs during verification
+
+The preserved Kimi output was not accepted from prose. Initial controller execution found and repaired:
+
+1. a missing `_git` helper that made the dependency verifier raise `NameError`;
+2. assumptions resolved relative to the repository root rather than the llama manifest directory;
+3. the documented `verify`/`reverse` contract was not wired into the CLI or apply path;
+4. assumptions and control-plane/license boundaries were defined but never enforced during apply;
+5. a stale Python test hardcoded the old two-patch count;
+6. the native fixture made an invalid strict resident-buffer-size comparison. Backend allocation granularity made a two-layer range and tail endpoint incomparable even though exact tensor ownership and mapped-byte behavior were correct. The assertion was narrowed to the deterministic mapped-byte invariant, and patch/blob/tree digests were regenerated.
+
+## Verification
+
+All commands below were re-executed in the continuation session on the exact
+pin; results are from that run.
+
+```text
+cd packages/node/native/llama/patches && sha256sum -c SHA256SUMS

+
+python scripts/llama_cpp_dependency.py inspect
+# exact commit/tree, MIT license, five-patch series, no model downloads

+# exit 0
+```
+
+Focused native gate against the patched exact pin (apply first because `verify`
+intentionally restores the source checkout to pristine state, then reverse after
+the test):
+
+```text
+python scripts/llama_cpp_dependency.py apply --source-dir build/llama.cpp/source

+```
+
+Build-directory note: `build/llama.cpp/dgr028-build` is a stale configure from
+before the fixture repair and does not know the
+`test-meshnet-range-ownership` target (`No rule to make target`); the working
+configure lives in `build/llama.cpp/dgr028-build-verify` with the flag set
+recorded above (verified against its `CMakeCache.txt`). Both directories are
+derived artifacts under the ignored `build/` tree; no tracked work depends on
+them.
+
+A broad `cmake --build ... --target test` was also attempted after building only the focused target. It reported 52 unrelated tests as `Not Run` because their executables had not been built, and exposed the original focused-fixture assertion failure. It is not presented as a full-suite gate. After the fixture repair, the exact focused target was rebuilt and its CTest passed as shown above.
+
+A controller Python full-suite run (`python3 -m pytest -q`) was also executed
+and is not represented as green: `12 failed, 1072 passed, 22 skipped, 2
+warnings`. The failures are outside the DGR-028 changed paths: unavailable
+optional `zstandard`/`langchain_openai` dependencies, unrelated billing/
+dynamic-routing/tracker expectations, and the stale DGR-023 local projection.
+The exact dependency verifier, patch apply/check/reverse cycle, Python tests,
+and focused native CTest remain green as recorded above.

+- This is patch-stack and model-free native fixture evidence, not real-model correctness, memory-fit, performance, or route certification.
+- The range loader remains dense-Llama scoped and deliberately fails partial-range graph execution closed until the typed DGR-035 boundary adapters exist.
+- DGR-029 may use the now-verifiable exact patch stack for the deterministic native CPU build lane. DGR-034 owns real dense-Llama range behavior and memory evidence.

+## Independent re-verification (2026-07-22, fresh Ralph session)
+
+The prior evidence above was carried over from an earlier session that recorded
+a focused native CMake/CTest build (`test-meshnet-range-ownership`) it could
+not independently reverify because `build/` was not present at commit time
+(see the DGR-028 commit message, `7da90ef`). This session re-ran the

+`cmake` is not installed in this environment (`which cmake` fails), so the
+native CMake/CTest build claim from the prior session (`test-meshnet-range-ownership`
+1/1 Passed) could **not** be independently re-executed here; it is neither
+re-confirmed nor retracted, just carried forward from `7da90ef` without a new
+build-verified claim in this session. Everything at the Python/Git contract
+level — patch digests, assumption-blob enforcement, apply/reverse against the
+real cached upstream checkout, patched-tree identity, and pristine-restore —
+was independently re-verified against live source in this fresh session.
+
+## prd.json repair (unrelated to DGR-028 itself)
+
+Before editing `DGR-028.passes`, `prd.json` was found with its top-level
+`sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/`supersededStories`
+fields silently dropped again (`branchName` was also missing but had already
+been restored by a prior in-flight edit) — the same ralph-tui round-trip bug
+documented for DGR-019/DGR-020. Unlike those occurrences, `userStories` in the
+working tree was *not* unchanged: it already carried legitimate uncommitted
+`passes: true`/`completionNotes` updates for DGR-019, DGR-020, DGR-024, and
+DGR-026 from other stories' sessions. The missing top-level sections were
+restored from `git show HEAD:.scratch/distributed-gguf-runtime/prd.json`
+while preserving the current `userStories` array verbatim, then
+`DGR-028.passes` was set `true` with `completionNotes` added, and
+`.scratch/distributed-gguf-runtime/issues/028-implement-numbered-patch-stack-apply-and-verification.md`
+was regenerated via `scripts/ralph_prd_schema.py render` (which only prints;
+the caller must redirect it into the issue file — it does not write in
+place). `python3 scripts/ralph_prd_schema.py validate` and
+`python3 -m pytest -q tests/test_ralph_prd_schema.py` (108 passed) both pass
+against the repaired file.

+# DGR-029 evidence — native CMake skeleton and deterministic CPU lane
+
+**Status:** implementation complete, live-verified in this session (2026-07-22).
+**Authority:** local `prd.json` is authoritative; Gitea is a projection.
+**Upstream pin:** `e920c523e3b8a0163fe498af5bf90df35ff51d25` (`llama.cpp`, from `UPSTREAM_LOCK.json`).
+
+## What existed before this session
+
+`scripts/llama_cpp_dependency.py` already had `build()`, `smoke()`, and `reproduce()`
+functions and `UPSTREAM_LOCK.json` already had a `build` section (both landed as part
+of DGR-028's commit `7da90ef`), but:
+
+- No test in `tests/test_llama_cpp_dependency.py` ever exercised `build`/`smoke`/`reproduce`
+  — only `fetch`/`apply`/`reverse`/`inspect` had coverage.
+- `cmake` was not installed in the DGR-028 session's environment ("`cmake` is not installed
+  in this environment," per its evidence), so this lane was never actually run end to end;
+  DGR-028's own live-verified CTest evidence used a one-off manual `cmake`/`ctest` invocation
+  with `-DLLAMA_BUILD_TESTS=ON` outside this driver, against a build directory that no longer
+  exists in this session.
+- The locked `configure_flags` did not force CPU-only backend options (`GGML_CUDA`/`GGML_HIP`/
+  `GGML_VULKAN`/`GGML_METAL`/`GGML_BLAS`) — relying on upstream per-platform defaults (which
+  happen to default OFF on Linux, but are undocumented and platform-dependent), and
+  `LLAMA_BUILD_TESTS` was `OFF`, so no CTest lane existed at all — only a `--help` smoke check
+  against the unrelated stock `llama-gguf-hash` tool.
+
+This session found and closed those three gaps rather than re-implementing from scratch.
+
+## What changed in this session
+
+- `packages/node/native/llama/UPSTREAM_LOCK.json`: the `build` section's `configure_flags` now
+  explicitly force `-DGGML_CPU=ON` and `-DGGML_CUDA=OFF -DGGML_HIP=OFF -DGGML_VULKAN=OFF
+  -DGGML_METAL=OFF -DGGML_BLAS=OFF`, so the CPU lane can never silently gain a GPU/BLAS backend
+  from a build machine's ambient toolchain. `-DLLAMA_BUILD_TESTS` flipped `OFF` → `ON` (required
+  so the `test-meshnet-range-ownership` CTest target exists at all — configuring
+  `LLAMA_BUILD_TESTS=ON` does not itself build every upstream test, only registers them; the
+  `native_targets` list still controls what actually gets compiled). Added `native_targets` entry
+  `test-meshnet-range-ownership` and a new `ctest_regex` field
+  (`"^test-meshnet-range-ownership$"`) naming the exact deterministic model-free fixture CTest
+  added by DGR-028's patch 0005.
+- `scripts/llama_cpp_dependency.py`: factored `_cmake()`'s override/PATH/venv-sibling resolution
+  into a shared `_toolchain_binary(name, env_var)` and added `_ctest()` using the same resolution
+  (`CTEST` env override, PATH, or the sibling of the resolved `cmake` binary's environment). Added
+  `ctest_lane(build_dir)`, which loads the lock's `ctest_regex` and runs
+  `ctest --test-dir <build_dir> -R <regex> --output-on-failure`, printing output on success and
+  raising `DependencyError` (via the existing `_run` wrapper, which already attaches
+  stdout/stderr detail) on failure. Added a `ctest` CLI subcommand (`--build-dir`). Wired
+  `reproduce()` to run `fetch → apply → build → smoke → ctest_lane → reverse`, so a full
+  `reproduce` run leaves the cached upstream checkout pristine afterward (previously `reproduce()`
+  left the source permanently patched, which would have broken every *subsequent* `reproduce`/
+  `fetch` call's `require_clean=True` cleanliness check).
+- `tests/test_llama_cpp_dependency.py`: added
+  `test_build_config_locks_an_explicit_cpu_only_deterministic_lane` (offline; asserts the lock's
+  `configure_flags` are CPU-only and that `ctest_regex`/`native_targets`/`smoke_binary` all agree
+  with each other and with `patched_paths`) and
+  `test_ctest_lane_raises_an_actionable_error_for_a_failing_named_test` (gated on `cmake`
+  availability via a `requires_cmake` marker mirroring `test_native_identity_emission.py`'s
+  `requires_cc` pattern; builds a tiny synthetic two-test CMake project — not the full llama.cpp
+  tree, so it runs in about a second — and proves `ctest_lane()` both passes silently on a passing
+  named test and raises `DependencyError` naming the failing test on a failing one).
+
+## Toolchain note
+
+Neither the ambient system Python nor `.venv-rocm` has `cmake`. This session installed `cmake`
+(the PyPI wheel that bundles prebuilt binaries, version 4.4.0) into the pre-existing repo-root
+`.venv` used by earlier DGR-024/DGR-026 sessions (`.venv/bin/cmake`, `.venv/bin/ctest`), which was
+already on-disk from a prior session but had never had `cmake` installed into it. All commands
+below were run with that `.venv/bin` prepended to `PATH`. This is the same "disposable venv for a
+lightweight optional dependency" pattern DGR-024 used for `grpc`.

+
+## Ensuring build success does not advertise capability
+
+- The locked `configure_flags` disable every accelerator backend explicitly
+  (`GGML_CUDA/HIP/VULKAN/METAL/BLAS=OFF`) rather than relying on per-platform defaults, so a
+  successful configure/build can only ever mean "the CPU reference backend compiled" — never an
+  accelerator claim, and never dependent on whether the build host happens to have a GPU SDK
+  installed.
+- `meshnet-build-metadata.json` (written by `build()`) records `model_downloads: false` and
+  `semantic_certification: false` alongside the exact commit/patch/flag identities — the artifact
+  itself, not just prose, states this build proves toolchain compilation only.
+- The two targets actually compiled are `llama-gguf-hash` (a stock upstream file-hashing utility;
+  no inference) and `test-meshnet-range-ownership` (a model-free fixture that writes a tiny
+  synthetic GGUF and asserts range-ownership bookkeeping — no real model, no generation, no
+  numerical/backend correctness claim). Neither exercises inference, MoE, attention, or any
+  DeepSeek V4 semantic path.
+
+## Changed files
+
+- `packages/node/native/llama/UPSTREAM_LOCK.json`
+- `scripts/llama_cpp_dependency.py`
+- `tests/test_llama_cpp_dependency.py`
+- `.scratch/distributed-gguf-runtime/prd.json`
+- `.scratch/distributed-gguf-runtime/issues/029-create-the-native-cmake-skeleton-and-deterministic-cpu-lane.md`
+- `.scratch/distributed-gguf-runtime/evidence/DGR-029/README.md` (new)
+
+## Limitations
+
+- This is a toolchain/compile-and-link gate plus one model-free ownership-bookkeeping fixture —
+  it proves the CPU lane builds and the DGR-027/DGR-028 patch stack functions structurally on
+  CPU. It proves nothing about real-model correctness, memory-fit, performance, or any
+  backend/model/recipe certification; `stock_glm_limitations` in `UPSTREAM_LOCK.json` and DGR-028's
+  own limitations continue to apply unchanged.
+- `cmake`/`ctest` are not installed system-wide or in `.venv-rocm` in this environment; they were
+  installed only into the pre-existing repo-root `.venv` for this session's verification (and for
+  the new gated pytest test, which is skipped in any environment lacking `cmake`). A future session
+  without that `.venv` (or without re-installing `cmake` into it) will see the same "cmake is
+  unavailable" actionable failure demonstrated above, not a silent pass.
+- Only the two named targets are compiled (`llama-gguf-hash`, `test-meshnet-range-ownership`); a
+  broad `cmake --build ... --target test` / full upstream test suite is out of scope here, exactly
+  as DGR-028 recorded ("not presented as a full-suite gate").
+- CUDA/ROCm/Vulkan/Metal compile lanes remain unimplemented; this story only establishes the CPU
+  lane "before accelerator matrix work," per its objective. Those lanes are separate future work.
+
+## Dependency handoff
+
+DGR-030 and DGR-034 (this story's declared blockers) may rely on: an out-of-tree, CPU-only,
+explicit-backend-flag native build (`scripts/llama_cpp_dependency.py build`/`reproduce`) that
+compiles the exact DGR-027/DGR-028 patched pin and runs a real CTest lane
+(`test-meshnet-range-ownership`) proving the patch stack's range-ownership bookkeeping compiles
+and passes on CPU. Any accelerator (CUDA/ROCm/Vulkan/Metal) lane, any real-model load, and any
+backend/model/recipe capability certification remain unimplemented and must not be assumed from
+this story's green build alone.

-# Ralph task evidence
+# Distributed GGUF Runtime evidence
 
-Each completed story creates `evidence/<TASK-ID>/README.md`. Fresh dependent iterations must read it before coding.
+> **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.
 
-Required README sections:
+## Authority and classes
 
-1. Summary and acceptance decision.
-2. Exact files changed.
-3. Commands run and real exit/results.
-4. Correctness, performance and hardware evidence classification.
-5. Known limitations and deferred work.
-6. Compatibility/migration notes.
-7. Explicit handoff for each dependent story.
+Evidence supports but never overrides `prd.json`. Valid classes are `model-free`, `fixture`, `real-model`, `real-hardware`, and `release`; lower classes cannot satisfy higher-class acceptance. Legacy DGR-001..016 directories remain unchanged for DGR-017 provenance audit and confer no completion credit.
 
-Store raw machine-readable metrics, manifests and protocol artifacts beside the README. Never store secrets, model weights, build outputs or Ralph iteration logs here.
+## Future story layout
+
+Each DGR-017..071 story writes `evidence/<ID>/README.md` with summary, exact changed files, exact commands and real outputs, limitations, compatibility/migration notes, and dependent-story handoff. Machine-readable contracts, manifests, metrics, and raw logs live beside it. Never fabricate output.
+
+Real runs record exact model SHA and all split hashes, tokenizer, quant/recipe, llama.cpp pin+patch identity, backend/driver/toolchain, host/hardware/network, commands/environment (without secrets), raw parity/performance/resource results, and evidence class. Models live on configured mounted-drive storage, never `/home`.
+
+Routing certification records prove only the exact exercised backend/model/recipe lane. Compile-only, fixture, failed, or unavailable lanes remain registered-dark. V4 cache/state evidence must show KV and CSA/HCA/SWA/indexer/compressor data remain shard-local/session-keyed; route recovery evidence must show cache miss plus re-prefill/restart, not migration.

-# Focused implementation strategy: performant concurrent distributed inference
+# Distributed GGUF Runtime implementation strategy
 
-Status: Accepted planning direction
-Last updated: 2026-07-13
+> **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.
 
-## Product objective
+## Execution model
 
-Enable clients to run top open models that do not fit on one consumer machine by combining independently owned model Shards into performant, concurrent Inference Routes.
+Execute one numerically ordered, dependency-ready story per fresh Ralph context. Read `RALPH-CONTEXT.md`, source issue, and dependency evidence first; use TDD/fixture-first verification; finish with exact evidence. `prd.json` is the only state authority.
 
-The alpha-release target is the exact `zai-org/GLM-5.2` model, pinned by revision and served with `reasoning_effort=max`, using the smallest published Unsloth `UD-IQ1_S` GGUF across physical consumer machines. See [GLM-5.2-MAX-ALPHA-ROADMAP.md](GLM-5.2-MAX-ALPHA-ROADMAP.md). Dense Llama remains a cheap structural fixture; Qwen expansion is post-alpha.
+## Sequence
 
-The project is not trying to reproduce every vLLM feature or support every inference engine. It is optimizing for:
+1. **M0 DGR-017..020:** reconcile legacy reality, lock metadata/performance contracts, and run the independent whole-model baseline.
+2. **M1 DGR-021..033:** protocol/lifecycle/codegen, exact identities and split artifacts, pinned upstream/patches, CPU then accelerator builds, `ShardEngine`, fixtures, fake worker.
+3. **M2 DGR-034..043:** dense ranged ownership/boundary/parity/local state, worker integration, supervision/direct-relay, and measured GGUF inputs to unchanged routing.
+4. **M3 DGR-044..054:** pin/inventory V4, adapt upstream boundary/local state/MoE/hash execution, pass parity and real 2–4 scenario, then enforce alpha with MTP off.
+5. **M4 DGR-055..067:** batching/backpressure/failure/recovery/long-context, existing-routing 10+ certification, real scale, measured optimization/compression, MTP contract+implementation, hardware certification.
+6. **M5 DGR-068..071:** packages, human upstream collaboration, beta gate (including MTP), and pin/patch/certification maintenance.
 
-1. Models larger than one node's RAM/VRAM.
-2. Useful interactive decode speed on consumer CPU, AMD, NVIDIA, Vulkan, and mixed routes where certified.
-3. Multiple concurrent Route Sessions without cache corruption or global serialization.
-4. A lean runtime with one control plane and one primary GGUF engine.
-5. Measured improvement over the existing Transformers/safetensors implementation.
+## Guardrails
 
-## Current reality
 
-The existing project already owns the differentiating distributed control plane:
+## Locked scope
 
-- Tracker-selected contiguous Shards.
-- Stable Route Sessions.
-- Local per-Shard Hot KV State in the Transformers reference backend.
-- Binary Activation Seams.
-- Relay/direct routing, cancellation, telemetry, billing, and capability admission.
-- Persistent relay and direct transport optimizations.
+- 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.
 
-The missing production path is a native GGUF execution worker that can load and execute only an assigned layer range while retaining local Hot KV State for concurrent Route Sessions.
+## Target identities
 
-Whole-model llama.cpp, vLLM, and existing Transformers serving remain baselines or optional route kinds. They are not substitutes for native distributed Shards.
+- 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`.
 
-## Performance hypothesis—not an assumption
-
-GGUF itself is a format. Performance comes from llama.cpp/GGML's quantized kernels, memory layout, mmap, backend scheduling, and reduced working set.
-
-Quantized GGUF may be faster or may merely fit a larger model. Comparisons against safetensors must report both speed and quality because BF16 safetensors and Q4/Q8 GGUF are not numerically equivalent.
-
-Before expensive native work, establish controlled lanes. DGR-001 remains immutable; DGR-017 adds a target-specific fit and semantics contract without rewriting DGR-001 evidence:
-
-- Same model architecture and upstream revision.
-- Same machine, prompt set, context, output length, sampling policy, and concurrency.
-- Transformers/safetensors BF16 or the current production recipe.
-- llama.cpp GGUF F16/BF16 or Q8 correctness lane where available.
-- Q4_K_M or selected production quantization performance/fit lane.
-- TTFT, prefill tok/s, decode tok/s, p50/p95 latency, RSS, VRAM, artifact size, energy where available, and output-quality drift.
-
-The program proceeds only if llama.cpp/GGUF provides at least one meaningful advantage recorded in a machine-readable performance contract:
-
-- Better decode or aggregate throughput at acceptable quality; or
-- Materially lower memory that makes the target model routable while preserving useful throughput.
-
-## Parallelism we will use
-
-### Public Inference Route: layer/pipeline parallelism
-
-Each node independently executes one contiguous Shard. Activations cross seams; weights and Hot KV State remain local.
-
-This is the only public cross-machine model-parallel primitive in the first runtime.
-
-### Per-node continuous batching
-
-Autoregressive tokens remain sequential within one generation. Throughput comes from batching decode steps from multiple active Route Sessions inside each node using llama.cpp batches and sequence IDs or bounded context pools.
-
-This is essential. A worker that globally serializes sessions is not production-ready.
-
-### Multiple complete routes: data parallelism
-
-The Tracker may select multiple complete routes for independent requests. This increases network throughput and availability without requiring collectives between routes.
-
-### Trusted composite node: optional tensor/expert parallelism
-
-Tensor parallelism and expert parallelism require frequent collectives and tight compatibility. They may be used later inside one operator-controlled composite node or managed cluster exposed as one logical provider. They are not public WAN routing primitives.
-
-### Deferred mechanisms
-
-- Disaggregated prefill and KV transfer.
-- Speculative decoding.
-- Cross-route prefix snapshots.
-- Route repair with KV migration.
-- Public tensor/expert parallel collectives.
-
-They remain out of the critical path until the native layer route passes performance and concurrency gates.
-
-## Reuse decisions
-
-### llama.cpp/GGML: primary runtime substrate
-
-Reuse:
-
-- GGUF parsing and mmap.
-- Quantized kernels.
-- CPU, CUDA, HIP/ROCm, Vulkan, Metal, and other supported backends.
-- Tokenizer and model architecture implementations.
-- KV and sequence operations.
-- Backend scheduler and graph execution.
-
-Maintain a small exact-commit fork only for the missing local seam:
-
-- Range-aware tensor ownership/loading.
-- Architecture-defined boundary input/output.
-- Intermediate boundary output without tail normalization.
-- Layer-filtered KV and sequence mapping.
-
-Keep networking, Tracker logic, billing, and public protocol outside llama.cpp. Upstream generic hooks where possible.
-
-### vLLM: concepts and optional managed backend
-
-Use unmodified vLLM only as:
-
-- A whole-model node backend.
-- A managed TP/PP/EP cluster represented as one logical provider.
-- A performance/correctness baseline.
-
-Adapt concepts, not runtime code:
-
-- Named intermediate tensor bundles.
-- Continuous batching and request-owner maps.
-- Versioned KV-transfer compatibility fingerprints.
-- Explicit send/receive/abort/failure lifecycle.
-- Load telemetry and unbiased route selection.
-
-Do not fork vLLM for public Shards and do not transplant PagedAttention, Torch process groups, or GGUF-plugin kernels into the llama.cpp worker.
-
-### Nakshatra, prima.cpp, llama-gguf, LiGGUF, GPUStack
-
-Use as source and test donors only:
-
-- Nakshatra: partial-GGUF patches, daemon concepts, replay cases.
-- prima.cpp: selected tensor ownership and local-layer KV evidence.
-- llama-gguf: small protocol and integration-test patterns.
-- LiGGUF: Q8 activation transport and tensor-reduction reference.
-- historical GPUStack: resource preflight and role-oriented placement.
-
-Do not adopt or fork their repositories wholesale.
-
-### Mesh-LLM GLM branch: focused test/patch donor only
-
-Use its GLM-5.2 branch to study DSA, IndexShare, stage-local KV, and sideband tests. Do not import its scheduler, discovery/control plane, package manager, or broad llama.cpp patch stack. Every adopted idea must be independently understood, minimized, attributed, and tested against our exact pin.
-
-## Battle-proven transport decision
-
-Use gRPC over HTTP/2 with Protocol Buffers for the native C++ Shard worker protocol.
-
-Why:
-
-- Mature Python and C++ implementations.
-- Bidirectional streaming.
-- HTTP/2 flow control and connection reuse.
-- Deadlines, cancellation, status codes, TLS, authentication interceptors, and generated schemas.
-- Avoids inventing a socket protocol.
-
-Scope boundary:
-
-- OpenAI-compatible client/Gateway APIs remain HTTP/SSE.
-- Tracker/control APIs remain existing project interfaces.
-- One long-lived bidirectional gRPC stream serves one Route Session Activation Seam.
-- Existing relay/WebSocket infrastructure may carry the same versioned protobuf frames as opaque binary when direct gRPC reachability is unavailable.
-- Large prefill tensors are chunked into bounded frames; decode bundles stay small.
-- No QUIC/WebRTC/custom transport in this milestone.
-
-The public boundary uses a versioned named-tensor bundle rather than one anonymous tensor because architecture boundaries can require more than `hidden_states`. DGR-006 updates the current single-`NamedTensor` decode fast path to carry the same bundle semantics and adds an explicit typed tail logits/token result with sampling/template identity.
-
-Minimum identity:
-
-```text
-schema version
-request/work id
-Route Session id and route epoch
-Model Artifact and runtime recipe fingerprint
-Shard range and effective start
-phase: prefill/decode/release/cancel
-position/token range
-named tensors with shape/dtype/byte order
-compression and checksum
-idempotency step id
-cache expectation/result
-```
-
-## Concurrency model
-
-A native worker must not use one global serving sequence or one lock around all model execution.
-
-Required ownership:
-
-```text
-(Route Session id, route epoch)
-    -> local sequence/context
-    -> Shard-local Hot KV State
-    -> bounded lease and memory accounting
-```
-
-The node scheduler:
-
-- Admits sessions against model memory and KV budget.
-- Forms compatible decode batches from active sessions.
-- Preserves per-session position and route order.
-- Applies bounded queues and backpressure.
-- Cancels/releases independently.
-- Reports queue, batch, KV, prefill, decode, and seam telemetry.
-
-Initial deterministic gate: at least four concurrent sessions on a small certified model with no token/KV cross-talk. Final concurrency targets are hardware/recipe-specific and recorded by capability admission rather than hardcoded globally.
-
-## Stage gates
-
-### Gate A: performance hypothesis
-
-Controlled safetensors-versus-GGUF benchmark produces a signed/reproducible report and locks thresholds. Stop native work if there is no meaningful speed or fit benefit.
-
-### Gate B: local range parity
-
-Two local processes own disjoint GGUF ranges and match whole-model llama.cpp within the certified numerical tolerance for prefill and greedy decode.
-
-### Gate C: concurrent KV
-
-Multiple Route Sessions prefill/decode concurrently with isolated local KV, bounded memory, cancellation, and release.
-
-### Gate D: real distributed route
-
-Two physical machines execute one model that uses both Shards. Synthetic activation tests do not satisfy this gate.
-
-### Gate E: consumer-hardware performance
-
-On certified consumer hardware, the GGUF route beats the current distributed safetensors route under the locked performance contract or enables a larger otherwise-unroutable model at useful measured speed.
-
-### Gate F: exact GLM-5.2 alpha target
-
-After the generic dense fixture proves range and boundary mechanics, certify explicit GLM-5.2 MoE, MLA KV, DSA, IndexShare, and NextN policy. Alpha requires the exact `UD-IQ1_S` target across physical consumer nodes, native Max-mode semantics, locked parity/usefulness/performance thresholds, and bounded failure cleanup. Qwen3/Qwen3-MoE is later architecture expansion.
-
-## Scope discipline
-
-The following do not block the first production candidate:
-
-- New cryptocurrency/economics work.
-- New artifact P2P protocol.
-- QUIC or WebRTC.
-- vLLM fork.
-- Whole-repository Nakshatra/prima adoption.
-- Every GGUF architecture.
-- Automatic route repair.
-- Prefix snapshot migration.
-- Speculative decoding.
-- A large-model marketing demo before small-model parity and concurrency pass.
-
-Every optimization must preserve output contract, session isolation, cancellation, resource cleanup, capability admission, and per-node attribution.
+DGR-020 cannot use distributed results. DGR-054 does not depend on MTP. DGR-070 depends on DGR-066. Compile support and scenario success never imply general routability.

+# DGR-022: Define Shard lifecycle and structured status RPCs
+
+- **Status / triage:** completed; `passes: true`
+- **Execution mode:** `AFK`
+- **Milestone:** `M1`
+- **Dependencies:** `DGR-021`

+- **Labels:** `area:protocol`, `area:lifecycle`, `type:infrastructure`, `priority:p0`, `ready-for-agent`
+- **Evidence class:** `model-free`
+- **Hardware:** `none`
+- **Model:** `generic`
+- **Upstream:** `no`
+
+## Objective / description
+
+Fresh Ralph session: read `.scratch/distributed-gguf-runtime/RALPH-CONTEXT.md`, source issue `.scratch/distributed-gguf-runtime/issues/022-define-shard-lifecycle-and-structured-status-rpcs.md`, and evidence READMEs for dependencies (DGR-021) before changing code. Inspect live source/tests rather than trusting legacy pass states. Objective: Complete the gRPC contract for worker capability, health, sessions, cancellation, release, and metrics.
+
+## Acceptance criteria
+
+- [x] Define capability, health, bidirectional session stream, cancellation, release, and metrics RPCs.
+- [x] Specify deadlines, cancellation propagation, bounded flow control, cache expectations/results, and structured error taxonomy.
+- [x] Specify TLS/auth hooks without moving Meshnet authentication or billing into the worker.
+- [x] Add compatibility tests for supported versions and fail-closed tests for unsupported versions and malformed lifecycle transitions.
+- [x] Applicable shared quality gates in `prd.json` pass, and the evidence handoff records exact commands/results, changed files, limitations, and dependency handoff.
+
+## Shared quality gates
+
+- Targeted deterministic tests pass; Python changes also pass `python -m compileall packages tests`.
+- `git diff --check` passes.
+- Default tests are model-download-free, API-credit-free, and GPU-free.
+- Evidence README records exact changed files, commands/results, limitations, and dependency handoff; no fabricated evidence or inherited completion credit.
+- Native changes pass focused out-of-tree CMake build and CTest; patch changes verify clean apply/check/reverse against the exact llama.cpp pin.
+- Runs are opt-in and record exact artifact/split hashes, runtime/upstream pin, backend/driver, hardware, network, commands, and raw metrics. Model artifacts use configured mounted-drive storage and never `/home`.
+- Preserve existing Transformers behavior and backend-agnostic Tracker routing/load balancing/billing/relay semantics unless an explicit versioned contract says otherwise. One scoped story commit is expected during execution, but this specification-materialization change is not committed.

+
+## Objective / description
+
+Build a real generated-gRPC protocol harness around the versioned shard_runtime.proto contract. Use generated Python and C++ stubs over an actual localhost transport and real process lifecycle; exercise captured deterministic protocol vectors and serialized protobuf bytes before a real model worker exists. Do not implement an in-memory fake transport, synthetic model outputs, or a production-looking stub/demo service.
+
+## Acceptance criteria
+
+- [x] Start a real localhost gRPC server process using generated bindings and connect to it with a generated client; no in-memory fake channel or direct method-only seam.
+- [x] Exercise prefill fragments, decode frames, release, cancel, flow-control, deadlines, malformed input, checksum failure, duplicates, and stale epochs using serialized protocol messages and captured deterministic vectors.
+- [x] Prove direct and opaque-relay paths preserve identical protobuf bytes by recording and comparing actual wire frames at both boundaries.
+- [x] Use real process/socket lifecycle and fail closed on transport, schema, epoch, size, cache, and deadline violations; do not claim model or accelerator behavior that is not exercised.
+- [x] Applicable shared quality gates pass, and evidence records exact commands, raw outputs, generated artifact identities, wire-frame hashes, changed files, limitations, and dependency handoff.
