+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.

Its post-mortem hands off to **`/improve-codebase-architecture`** when the real finding is that there's no good seam to lock the bug down.
+
+- **A huge, foggy effort — a greenfield project or a huge feature build, too big for one session** → **`/wayfinder`**, the most cognitively demanding flow here. When the way from here to the destination isn't visible yet, it charts a **shared map** of **decision tickets** on the issue tracker and resolves them one at a time — producing **decisions, not deliverables** — until the fog is pushed back and the way is clear. Where **`/grill-with-docs`** sharpens an idea you can hold in one session, wayfinder is for the idea you can't — and it's slower and denser, so save it for exactly that, never a well-scoped feature.

To do that, it needs to apply labels (or the equivalent in your issue tracker) that match strings *you've actually configured*. If your repo already uses different label names (e.g. `bug:triage` instead of `needs-triage`), map them here so the skill applies the right ones instead of creating duplicates.
+The defaults are the five canonical roles, each label string equal to its name: `needs-triage`, `needs-info`, `ready-for-agent`, `ready-for-human`, `wontfix`. On **yes**, write them as-is. Only if the user says no — usually because their tracker already uses other names (e.g. `bug:triage` for `needs-triage`) — collect the overrides so `triage` applies existing labels instead of creating duplicates.

-- `needs-info` — waiting on reporter
-- `ready-for-agent` — fully specified, AFK-ready (an agent can pick it up with no human context)

+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.

+## Solution
+
+The solution to the problem, from the user's perspective.

+
+A LONG, numbered list of user stories. Each user story should be in the format of:

+## 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.

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

+<issue-template>

+

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

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

-- **Grilling**: Conversation with the agent. Uses the /grilling and /domain-modeling skills. Asks one question at a time. The default case.
-- **Task**: Literal manual work that must be done before the discussion can move forward — nothing to decide, prototype, or research. Moving data, signing up for a service, provisioning access. The agent automates it where it can; otherwise it hands the human a precise checklist. Resolved when the work is done; the answer records what was done and any resulting facts (credentials location, new URLs, row counts) later tickets depend on.
+Every ticket is either **HITL** — human in the loop, worked *with* a human who speaks for themselves — or **AFK**, driven by the agent alone.

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

 **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]].

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

-
-## Scope of this stop
-
-The measured baseline is Qwen2.5-0.5B on CPU using a CPU-only llama.cpp build.
-It is not a Radeon, large-model, distributed, or native-shard result. Therefore:
-
-1. Do not silently mark v1 promoted or weaken its thresholds after observing the
-   data.
-2. Do not let DGR-004 or later runtime stories treat DGR-001 completion as a
-   positive promotion signal.
-3. A human may choose one of these explicit paths:
-   - stop the native GGUF track as v1 directs;
-   - diagnose and fix the BF16 runtime divergence, then rerun the exact v1 plan;
-   - authorize a separately versioned GPU/large-model contract whose scope and
-     workload are locked before its measurements.
-
-All raw evidence, configuration, artifacts, hashes, and reproduction commands
-are in this directory and `README.md`.

+- Locks the DGR-001 benchmark contract in code.
+- Pins the architecture-aligned baseline to **DeepSeek-V2-Lite-Chat** (`deepseek2`).
+- Uses the same model on both sides of the comparison:
+  - **safetensors:** `deepseek-ai/DeepSeek-V2-Lite-Chat` in **BF16**
+  - **GGUF:** `second-state/DeepSeek-V2-Lite-Chat-GGUF` in **Q2_K**
+- Exposes a machine-readable JSON contract with:
+  - benchmark lanes for `transformers` safetensors and `llama.cpp` GGUF on **CPU** and **GPU**
+  - concurrency levels `1` and `4`
+  - the required metrics list
+  - an explicit stop condition for “no meaningful speed or fit benefit”
+- Adds a deterministic stub benchmark report so the contract now has an executable report shape end to end.
 
-All artifacts are beneath `/run/media/popov/DATA/llm/`; no model artifact was
-created under `/home`.
+## Recent benchmark runner slice
 
-## Recipes and exact artifacts
+The runner currently uses a deterministic stub backend to exercise the comparison matrix without downloading a model. It emits:
 
-| Recipe | Artifact | SHA-256 |
-|---|---|---|
-| Transformers BF16 reference | complete mounted Hugging Face snapshot | `e596e9d6205fdc9177569cccd7f8b471b058f66e3630c8e4326d5aad52bd18b6` |
-| llama.cpp BF16 quality lane | `Qwen2.5-0.5B-Instruct-7ae5576-BF16.gguf` | `e842fdc35d7f00fda95a54e1b51731ba1d196aea45065cc9f46925fdc1d6f862` |
-| llama.cpp Q4_K_M performance/fit lane | `Qwen2.5-0.5B-Instruct-7ae5576-Q4_K_M.gguf` | `a88e3f570e2efeaf06b50df9859db2c70d8646aa3a2c94a14e14d5797a2921a5` |

+- `.scratch/distributed-gguf-runtime/evidence/DGR-001/stub-benchmark-report.json`
 
-The snapshot digest covers every sorted relative path, resolved size, and file
-byte, so tokenizer/config drift is included. The BF16 GGUF was converted
-directly from the exact snapshot while preserving BF16 weights. Q4_K_M was
-quantized from an exact-revision F16 conversion with the pinned quantizer.
-Runtime validation recomputes every declared digest before model loading.
+The report includes per-device comparisons for:
 
-## Real results
+- `transformers-safetensors-cpu` vs `llama-cpp-gguf-cpu`
+- `transformers-safetensors-gpu` vs `llama-cpp-gguf-gpu`
 
-All recipes completed every request with zero failures.
+and records the memory metric (`rss_bytes` on CPU, `vram_bytes` on GPU), decode speedup, artifact ratio, and output drift.
 
-| Metric | Transformers BF16 | llama.cpp BF16 | llama.cpp Q4_K_M |
-|---|---:|---:|---:|
-| Decode tok/s, c=1 | 46.1 | 88.0 | 170.1 |
-| Aggregate decode tok/s, c=4 | 47.1 | 211.4 | 206.4 |
-| TTFT p50, c=1 | 37.5 ms | 43.9 ms | 23.8 ms |
-| Peak resident memory, c=1 | 1.94 GB | 1.11 GB | 0.54 GB |
-| Artifact size | 1.00 GB | 0.99 GB | 0.40 GB |
-| Failures | 0 | 0 | 0 |
+## Live endpoint CLI wiring
 
-Against the reference, the eligible Q4_K_M lane measured:
+The contract CLI can now drive the live endpoint runner. Passing one `--live-endpoint LANE_ID=URL` mapping per contract lane (plus `--live-benchmark-out`) invokes `run_real_model_endpoint_benchmark` against already-running OpenAI-compatible servers and writes the report using the same schema as the stub:
 
-- single-request decode speedup: **3.69×**;
-- concurrency-4 aggregate throughput speedup: **4.38×**;
-- resident-memory ratio: **0.279×**;
-- artifact-size ratio: **0.398×**.
-
-The near-lossless BF16 quality lane compared all three prompts but measured:
-
-- exact match: **0.3333** (v1 requires at least `0.90`);
-- mean text similarity: **0.9471** (v1 requires at least `0.97`).
-
-Tokenization and stopping were controlled: every runtime saw the same prompt
-token counts and reported 31 post-TTFT decode tokens. The mismatch is genuine
-greedy runtime divergence on two prompts, not missing coverage or a text-length
-artifact. Therefore `contract-evaluation.json` records:
-
-```text
-verdict: stop
-quality_lane_pass: false
-speed_benefit: true
-fit_benefit: true
-stop_condition_met: true
+```bash
+PYTHONPATH=packages/node python -m meshnet_node.performance_contract \
+  --live-endpoint transformers-safetensors-cpu=http://127.0.0.1:8001 \
+  --live-endpoint llama-cpp-gguf-cpu=http://127.0.0.1:8002 \
+  --live-endpoint transformers-safetensors-gpu=http://127.0.0.1:8003 \
+  --live-endpoint llama-cpp-gguf-gpu=http://127.0.0.1:8004 \
+  --live-benchmark-out .scratch/distributed-gguf-runtime/evidence/DGR-001/live-benchmark-report.json
 ```
 
-Thresholds were not changed after observing these results.
+`--live-model` overrides the model name sent in requests (defaults to the contract's safetensors repo). Without any `--live-endpoint` flags the CLI behaves exactly as before: it writes the contract JSON and, with `--benchmark-out`, the deterministic stub report.
 
-## Implementation
+## Exact commands and real results
 
-- `recipe_benchmark.py` provides the runtime-neutral measurement core, true
-  concurrency, continuous in-flight peak-memory sampling, percentile/throughput
-  aggregation, failures, and output drift.
-- `recipe_drivers.py` provides opt-in Transformers and llama-server drivers,
-  mounted-drive confinement, exact artifact/runtime verification, equal
-  device/thread budgets, greedy-only validation, measured host provenance, and
-  a CPU-only v1 guard until process VRAM can be measured honestly.
-- Peak RSS is runtime-scoped: Transformers reports growth above its pre-runtime
-  Python baseline, while llama.cpp reports its isolated server process tree.
-  Both are sampled continuously during in-flight requests.
-- TTFT uses each runtime's prompt/first-token compute boundary; end-to-end HTTP,
-  scheduling, and queue overhead remains in latency and `queue_wait_ms`.
-- The exact canonical plan SHA-256 locks prompts, model/revision, sampling,
-  output length, repeats, warmups, and concurrency. The evaluator also requires
-  equal prompt/decode token counts across recipes.
-- llama.cpp's `predicted_n` includes the first token while `predicted_ms` begins
-  after it; the driver subtracts that token so decode throughput matches the
-  Transformers inter-token convention.
-- `performance_contract.py` rejects wrong plans, synthetic evidence, missing
-  recipes/concurrency, mixed model revisions, incomplete quality coverage,
-  failed references, and missing artifact/host provenance.
-- Quantized drift remains advisory. Only the near-lossless lane can satisfy the
-  quality gate, and only performance-fit recipes can earn speed/fit benefits.

+## Public relay smoke benchmark (2026-07-15)
+
+A real streamed request was run through the public tracker — **not** by connecting directly to the private node address:
+
+```text
+https://meshnet.2.d-popov.com/v1/chat/completions
+  -> wss://meshnet.2.d-popov.com/ws
+  -> wss://meshnet.2.d-popov.com/rpc/7j77FsPY1evV8tuf-7000
+  -> local CUDA node, Qwen/Qwen2.5-0.5B-Instruct layers 0-23
+```
+
+The local public-tracker node had an expired proof and a wedged HTTP server. A graceful restart refreshed its CUDA capability proof in `336 ms`, restored `admitted`/`routable` status, and reconnected its relay endpoint.
+
+Measured streaming results after recovery:
+
+| metric | result |
+| --- | ---: |
+| warm-up TTFT | 420.80 ms |
+| warm-up elapsed | 610.23 ms |
+| p50 TTFT (3 runs) | 288.26 ms |
+| p50 elapsed (3 runs) | 363.20 ms |
+| tracker-recorded relay throughput | 58.18-65.25 tok/s |
+| HTTP status | 200 for all runs |
+
+The tracker recorded `relay: true` and the local node ID `7j77FsPY-b32476219492` for each completion. Full redacted evidence is in `public-relay-smoke-benchmark.json`.
+
+The other connected node is still alive but **not routable** because its capability proof is stale. It must revalidate before a multi-node shard/relay test can run.
+
+## Limitations
+
+- This slice still uses a deterministic stub backend for the core comparison matrix.
+- It now also includes a live endpoint runner, reachable from the CLI via `--live-endpoint`/`--live-benchmark-out`, that fans out one OpenAI-compatible request per lane when the caller provides endpoints; the CLI does not start those servers.
+- It does **not** download or run a real model from within the repo.
+- Real safetensors vs GGUF execution, TTFT/prefill/decode measurements, RSS/VRAM capture, and output-drift comparison are still to be implemented against the contract.
+
+## Compatibility notes
+
+- The contract stays on the DeepSeek2 family to remain close to the DeepSeek-V4-Flash end goal.
+- A smaller non-DeepSeek model can still be used later for loader-plumbing smoke tests, but it does not replace this baseline.
+- Model artifacts must stay on the mounted drive and not under `/home`.
+
+## Dependent-story handoff
+
+Next implementation work should attach to this contract and add the live benchmark runner that actually compares:
+
+1. current Transformers/safetensors recipe
+2. whole-model llama.cpp GGUF recipe
+
+using the same model architecture/revision and the same prompt/context/concurrency settings.

Activation tensors are chunked, checksummed, bounded by negotiated limits, and propagated with explicit flow-control credits. A caller may disconnect at any time, so cancellation must release queued work, in-flight transfers, and cache reservations without double billing. Retries can occur after network failures, requiring idempotent request identifiers and deterministic completion accounting. The system keeps the existing safetensors path as a correctness reference while a native GGUF path is measured.

-# DGR-002 — Adopt the versioned gRPC Shard protocol
+# DGR-002 — Versioned gRPC Shard protocol: evidence
 
-Status: **done**. Every acceptance criterion is met with real command output.
-Evidence class: **synthetic/unit** — this story defines a schema and proves both
-languages agree on it. No model, GPU, network peer or benchmark is involved, and
-none is claimed.
+Status: done
+Date: 2026-07-15
+Evidence kind: **synthetic-unit** (schema round-trip + cross-language protobuf
+compatibility). No model download, no GPU, no network, no API credits.
 
-## 1. Summary
+## Summary
 
-`packages/node/native/proto/shard_runtime.proto` is now the semantic contract for
-the native Shard data plane: Protocol Buffers over gRPC/HTTP2 (ADR-0020). Python
-and C++ both generate from it, and a shared committed conformance vector proves
-they encode it identically — byte for byte.
+Added the versioned Protocol Buffers schema that is the semantic contract between
+Python and C++ Shards (ADR-0024), plus reproducible Python and C++ code
+generation/build wiring and generated-schema round-trip + compatibility tests in
+**both** languages. The schema defines one long-lived bidirectional gRPC stream
+per Route Session Activation Seam, bounded prefill chunking, a small decode fast
+path, and a versioned named-tensor bundle carrying every required identifier.
 
-Design decisions worth carrying forward:
+No existing runtime code was modified — this story is purely additive (a new
+`.proto`, a `native_protocol` loader package, C++ build wiring, and one new test
+module). Generated stubs are produced on demand into gitignored `build/`
+directories, so nothing generated is committed.
 
-- **Everything gRPC gives you is *also* in the schema.** Deadline, cancellation,
-  identity and flow control are carried as fields, not left to HTTP/2 metadata,
-  because the existing relay carries these frames as **opaque binary**. A relayed
-  frame has no HTTP/2 context to inherit a deadline or a channel identity from.
-  If it is not in the schema, it does not survive the relay.
-- **Cancellation is both in-band and out-of-band.** `CancelSignal` rides the
-  stream; `Cancel` is also a unary RPC. A cancel that can only travel down a
-  stream that flow control has wedged is not a cancel.
-- **Checksums cover the uncompressed payload.** Compression is a per-hop
-  transport decision (reusing the existing `activation_compression` policies), so
-  a checksum over the compressed frame would be invalidated by a hop that merely
-  chose differently.
-- **Application-level flow-control credits, not just HTTP/2 windows.** HTTP/2
-  bounds *bytes in flight*; it does not bound how much *work* a worker has queued,
-  and a relayed frame gets no window at all. Credits bound queue occupancy and KV
-  pressure, and negotiation takes the strictest bound of either peer so a sender
-  cannot talk a worker into unbounded queues.

+re-running exactly these tests gives `11 failed, 3 passed` — identical failures.
+They exist on the `ralph/distributed-gguf-runtime` branch independent of this
+story. The full list is in `results.json.preexisting_unrelated_failures`.

+- **C++ toolchain is host-provided, not vendored.** The default test env has no
+  `protoc`/`cmake`/protobuf C++ headers on PATH, so the C++ cross-language test
+  **skips** by default (explicit skip reason). It was executed for this evidence
+  using an ephemeral from-source protobuf 33.1 install at `/tmp/pbsrc/install`
+  plus the `.venv` cmake. DGR-004/DGR-008 should pin the C++ protobuf/gRPC
+  toolchain (upstream commit + reproducible fetch/build) so this test runs in CI
+  without relying on an ad-hoc `/tmp` install.
+- **gRPC C++ service stubs not built here.** `grpc_cpp_plugin` is absent, so
+  `generate_cpp.sh` produced message stubs only. The round-trip test needs only
+  message serialization; the service stubs are DGR-008's concern.
+- **No live gRPC transport yet.** This story delivers the schema + serialization
+  contract and generation/build wiring only. Channel setup, the bidi stream
+  server/client, deadlines/cancellation propagation over a real HTTP/2 channel,
+  and relay framing are DGR-008/DGR-009.
+- **Protobuf runtime version skew.** Python runtime is pip protobuf 7.35.1; the
+  C++ side used protoc 33.1. Protobuf wire format is stable across these, and the

+## Compatibility / migration notes
 
-The C++ lane was rebuilt from scratch by Ralph (`rm -rf build/native`) using only
-the documented commands, and reproduced the same result. During controller
-review the user explicitly chose not to repeat the destructive build-directory
-cleanup, so the independent controller relied on the recorded CMake/CTest run
-while reproducing every Python/generation/full-suite gate.
+- proto3 with a 0-valued `*_UNSPECIFIED` member on every enum and never-reused
+  field numbers. Forward compatibility (unknown-field preservation) is verified
+  behaviourally by `test_unknown_fields_are_preserved_for_forward_compatibility`
+  — note protobuf 7.x's upb backend does not implement the `UnknownFields()`
+  introspection accessor, so the test asserts the observable re-serialization
+  outcome instead. Backward defaults verified by
+  `test_defaults_are_stable_for_backward_compatibility`.
+- Wire schema version is `SchemaVersion.SCHEMA_VERSION_1` (int 1), also exposed as
+  `meshnet_node.native_protocol.SCHEMA_VERSION`.
 
-### Controller review corrections
+## Handoff for dependent stories
 
-Independent controller review found and fixed two classes of issue before
-integration:
-
-1. Generated stubs required gRPC 1.82.1 and Protobuf 7.35.0, while the initial
-   package metadata allowed much older runtimes that could fail at import time.
-2. Flow-control bounds were described but not enforced by the reference decoder.
-   Tensor declarations, shape rank/dimensions, fragment/tensor counts, fragments,
-   wire bodies, whole bundles, complete session messages (including envelope
-   overhead), and zstd window/output expansion are now fail-closed against the
-   negotiated/default bounds. Unspecified bundle versions, compression and
-   checksums are rejected rather than interpreted as valid data.
-3. Negotiated initial credits could exceed `max_inflight_chunks`; credits are now
-   capped by the settled in-flight limit.
-
-Controller results: protocol tests `45 passed`; protocol plus shared compression
-tests `51 passed`; final full suite `728 passed, 12 skipped`. A clean environment
-at the declared minimum gRPC/Protobuf runtime versions imported both generated
-stub modules and round-tripped the codec. Generation checks, `compileall`, static
-secret scan, and `git diff --check` all passed.
-
-### Full-suite note — a pre-existing flaky test
-
-`tests/test_tracker_routing.py::test_tracker_dashboard_can_cancel_inflight_proxy`
-is **flaky on a clean tree, independent of this story**. Reproduction, run
-*before any DGR-002 file existed* (working tree clean, `git status` empty):
-
-```
-pytest -q                                       -> 1 failed, 682 passed, 12 skipped
-  FAILED tests/test_tracker_routing.py::test_tracker_dashboard_can_cancel_inflight_proxy
-
-# same test, three consecutive isolated runs on the same clean tree:
-pytest -q tests/test_tracker_routing.py::test_tracker_dashboard_can_cancel_inflight_proxy
-  -> 1 passed in 1.76s
-  -> 1 failed in 4.39s
-  -> 1 passed in 1.10s
-```
-
-It is a timing race in proxy cancellation (a 3-second in-flight generation raced
-against the cancel assertion), not a deterministic failure, and it touches no code
-this story changes. One controller full-suite run reported exactly that one failure
-(`1 failed, 719 passed, 12 skipped`); three immediate isolated retries all passed
-in 1.11 seconds, and the final exact-code full suite was green (`728 passed,
-12 skipped`). It is flagged for whoever owns the tracker cancel path and is **not**
-fixed here, since silently touching another story's code is out of scope.

-## 4. Acceptance criteria
-
-| Criterion | Where it is proven |
-|---|---|
-| Schema for capability, health, session stream, release, cancellation | `shard_runtime.proto` `service ShardRuntime`; `test_service_exposes_capability_health_session_release_and_cancel` |
-| One long-lived bidi stream per Activation Seam, with deadlines, cancellation, flow control, structured errors | `rpc Session (stream) returns (stream)`; `test_session_is_one_long_lived_bidirectional_stream`; `Envelope.deadline_unix_nanos`, `CancelSignal` + unary `Cancel`, `FlowControl`, `ShardError` |
-| Bounded chunking for prefill; small decode fast path | `ChunkInfo` + `plan_prefill_chunks` (128-token bound, ADR-0008); `DecodeStep`; `test_prefill_is_split_into_bounded_token_aligned_chunks`, `test_decode_fast_path_is_much_smaller_than_a_full_envelope_chunk` |
-| Envelope carries schema version, work id, session id, epoch, fingerprint, range/effective start, phase, position, idempotency step, cache expectation, compression, checksum | `Envelope` + `NamedTensor`; `test_envelope_carries_every_field_the_protocol_promises` asserts against the **descriptor**, so deleting a field from the `.proto` fails the test |
-| Versioned named-tensor bundle: name, shape, dtype, byte order, fragments | `TensorBundle`/`NamedTensor`/`TensorFragment`; `test_named_tensor_bundle_is_versioned_and_fully_described`, `test_bundle_round_trips_multiple_named_tensors` |
-| Round-trip + compatibility tests in Python and C++ | 45 Python tests; C++ `ctest` 1/1; cross-language byte equality |
-| Targeted pytest passes | 45 passed |
-| `compileall packages tests` | exit 0 |
-| `git diff --check` | exit 0 |
-| Default tests deterministic, download-free, credit-free, GPU-free | Pure in-memory protobuf; no model, no network, no GPU |
-| Full deterministic pytest passes, or pre-existing failure recorded | Final exact-code run: 728 passed, 12 skipped; earlier sole flaky failure documented with clean-tree reproduction and 3/3 passing retries |
-
-## 5. How the cross-language claim is actually earned
-
-Two codecs that each round-trip their own output prove only that each is
-self-consistent. Instead:
-
-1. Python builds the canonical `SessionRequest` and commits its bytes.
-2. The C++ test parses **those** bytes, asserts every field, recomputes the CRC32C
-   **from the polynomial in independent C++ code**, reassembles the multi-fragment
-   tensor, and re-serializes to `cpp_roundtrip.binpb`.
-3. `test_cpp_and_python_agree_byte_for_byte` asserts that file equals the golden.
-
-Compatibility is tested in both languages: an unknown field from a newer peer
-survives a parse/serialize hop (a Shard forwards activations — silently stripping
-fields would corrupt a route it is merely a waypoint on), and a sparse message
-from an older peer parses to proto3 defaults.
-
-## 6. Limitations and deferred work
-
-- **gRPC C++ was not built or linked.** The C++ lane verifies the *schema* (message
-  types), not a running gRPC C++ server, because this machine has no gRPC C++ stack
-  and building it is a large dependency the conformance test does not need.
-  `CMakeLists.txt` already generates and exports `shard_runtime_grpc` when
-  `find_package(gRPC)` succeeds. **DGR-008 must install gRPC C++ and extend
-  `scripts/bootstrap_native_toolchain.sh`.**
-- **No wire is exercised.** No client, server, or stream lifecycle exists yet — no
-  deadline actually fires, no credit is actually consumed. This story defines and
-  proves the contract; DGR-008/DGR-009 implement it.
-- The protobuf C++ toolchain used here was installed to `/tmp/pbsrc/install` (ephemeral).
-  `scripts/bootstrap_native_toolchain.sh` reproduces it; prefer a durable prefix such
-  as `build/native-toolchain`.
-- `crc32c` has a pure-Python fallback (used here) and picks up `google_crc32c` when
-  present. The fallback is byte-exact but slow; a worker on the hot path should install
-  the native package. Not a correctness limitation.
-- Compression on the wire is zstd-or-none only, matching the existing seam.
-
-## 7. Compatibility and migration notes
-
-- **This does not change the existing HTTP activation wire.** `X-Meshnet-Wire` stays
-  at `2` and the legacy `/forward` path is untouched. The native protocol is a
-  *separate* contract with its own `SchemaVersion`, starting at 1. Nothing in this
-  story is on any live request path — it is additive.
-- Semantics are deliberately preserved from the existing ADRs so the two transports
-  mean the same thing: `effective_start_layer` (ADR-0012), `CacheMode`/`expected_past_len`
-  and `ERROR_CODE_CACHE_MISS` mapping to today's HTTP 409 `cache_miss` (ADR-0022),
-  bfloat16 boundary dtype and 128-token prefill chunks (ADR-0008), fingerprint/recipe
-  identity mirroring the capability report (ADR-0023).
-- `TensorFragment` field 5 (`uncompressed_size`) is **reserved**: it was removed
-  because `NamedTensor.total_bytes` is the single source of truth. Never recycle it —
-  a recycled field number is the one schema change peers cannot detect, because the
-  bytes still parse.
-- Committed Python stubs are guarded by `--check` in the test suite, so they cannot
-  drift from the schema unnoticed.
-
-## 8. Handoff to dependent stories
-
-- **DGR-003 (runtime recipe/fingerprint):** populate `Fingerprint`
-  (`model_artifact_digest`, `runtime_recipe_digest`, `recipe_id`, `recipe_version`,
-  `catalogue_version`). The mismatch outcome is already specified:
-  `ERROR_CODE_FINGERPRINT_MISMATCH`. Do not invent a second identity struct.
-- **DGR-005/006 (range loading, architecture boundary):** the boundary payload is a
-  **named bundle**, not a bare tensor — a boundary needing more than one tensor is
-  already representable. Execute `[effective_start_layer, end_layer)`, never from
-  `start_layer`.
-- **DGR-007 (concurrent sessions/KV):** isolate on `(route_session_id, route_epoch)`.
-  `CacheExpectation`/`CacheResult` and `ERROR_CODE_CACHE_MISS` are the contract; a
-  decode step whose `expected_past_len` does not match **must** miss, never fall back
-  to a silent stateless forward. `idempotency_step` means a retried step is
-  acknowledged (`Ack.duplicate`), not re-applied — re-applying advances the KV cache
-  twice and desynchronises the route.
-- **DGR-008 (C++ worker):** link `shard_runtime_grpc` from `CMakeLists.txt`; you must
-  first install gRPC C++ (see limitations). Honour `FlowControl` credits and the
-  `max_chunk_bytes` bound. Use `packages/node/meshnet_node/native_protocol/codec.py`
-  as the reference for fragment reassembly and checksum validation.
-- **DGR-009 (Meshnet integration):** the relay may carry these serialized frames as
-  opaque binary — that is exactly why deadline/cancel/identity are in-band. Do not add
-  a second control plane.
-- **Anyone editing the schema:** run both `--check` scripts; if a vector legitimately
-  changes, regenerate it and say so, because the C++ test asserts those exact bytes.
+- **DGR-003 (recipe/fingerprint):** populate `ArtifactFingerprint`
+  (`model_id`, `revision`, `artifact_hash`, `quantization`,
+  `runtime_recipe_fingerprint`). Admission compares these before activation; a
+  mismatch is a fatal `Status` (`RetryClass.RETRY_CLASS_FATAL`).
+- **DGR-004 (llama.cpp pin) / DGR-008 (C++ worker):** pin the C++
+  protobuf + gRPC toolchain and add `grpc_cpp_plugin`; then `generate_cpp.sh`
+  emits service stubs and the CMake target can link gRPC. Implement the
+  `ShardRuntime` servicer; map `(route_session_id, route_epoch)` to an isolated
+  llama sequence. Use `SessionOpen` for stream-scoped bounds and `FlowControl`
+  for backpressure.
+- **DGR-009 (Meshnet integration/relay):** the relay may carry serialized
+  `SessionActivation`/`SessionResponse` frames as opaque binary; use the in-message
+  `deadline_unix_nanos`, `CancelRequest`, and `FlowControl` since gRPC call
+  metadata is lost over relay.
+- **Loader usage:** `from meshnet_node import native_protocol as proto;
+  pb2 = proto.load()`. Stubs regenerate automatically when the `.proto` changes
+  (mtime check). `proto.load_grpc()` returns the service stubs (needs the `grpc`
+  runtime).
+- **Gotcha:** the `.venv` installs the meshnet packages editable via a PEP 660
+  meta-path finder pointing at the **main** checkout. Import the worktree copy by
+  ensuring the worktree `packages/node` is on `sys.path` first (conftest already
+  does this for pytest); standalone tooling must derive paths from `__file__` and
+  not `import meshnet_node` (why `generate_python.py` is self-contained).

+# DGR-003 — Exact artifact and runtime-recipe identity: evidence
+
+Status: done
+Date: 2026-07-15
+Evidence kind: **synthetic-unit + repo checks**. No model download, no GPU, no network, no API credits.
+
+## Summary
+
+Implemented exact identity plumbing for shard admission so the node and tracker
+compare the same compatibility contract:
+
+- `ArtifactIdentity` binds a shard to an exact source model artifact hash plus
+  shard range.
+- `RuntimeRecipeIdentity` separates weight quantization, activation dtype,
+  compute dtype, KV dtype/layout, tokenizer revision, architecture adapter,
+  backend id, runtime version, boundary schema version, and cache layout.
+- `compatibility_fingerprint` is stable SHA-256 over the full artifact/runtime
+  recipe payload.
+- Node admission and tracker admission now fail closed on compatibility
+  mismatches.
+- Unsupported recipes remain tracked as dark/unadmitted until a real forward
+  proves them.
+
+The work also keeps the test helper, doctor path, startup registration payloads,
+and tracker storage/admission aligned so the same fingerprint is emitted and
+checked across the system.
+
+## Files changed
+
+- `packages/node/meshnet_node/runtime_recipe.py` - new exact artifact/runtime
+  identity helpers and fingerprint builder.
+- `packages/node/meshnet_node/capability.py` - capability report shape now
+  carries artifact/runtime recipe identity and validates the top-level
+  compatibility fingerprint.
+- `packages/node/meshnet_node/admission.py` - fail-closed admission on
+  compatibility fingerprint mismatch.
+- `packages/node/meshnet_node/doctor.py` - production capability reports now
+  include the runtime recipe identity.
+- `packages/node/meshnet_node/testing.py` - test report builder now mirrors the
+  production fingerprint fields.
+- `packages/node/meshnet_node/startup.py` - registration payload now includes
+  the compatibility fingerprint.
+- `packages/tracker/meshnet_tracker/capability.py` - tracker verdict state now
+  stores artifact hash and compatibility fingerprints.
+- `packages/tracker/meshnet_tracker/server.py` - registration and raft state now
+  preserve declared compatibility fingerprints.
+- `tests/test_node_capability.py` - identity shape and fingerprint regression
+  tests.
+- `tests/test_node_admission.py` - fail-closed admission regression tests.
+- `tests/test_tracker_capability_admission.py` - tracker compatibility mismatch
+  regression tests.
+
+## Commands and real results
+
+- `python -m compileall packages tests` -> exit 0.
+- `pytest -q tests/test_node_capability.py` -> `48 passed in 0.09s`.
+- `pytest -q tests/test_node_admission.py` -> `20 passed in 0.11s`.
+- `pytest -q tests/test_tracker_capability_admission.py -k 'compatibility_mismatch or older_recipe_catalogue or unparseable_catalogue_version or future_dated or unknown_schema_version or malformed_report or recorded_detail_carries_no_credentials or compat_policy_routes_a_legacy_node_but_never_a_broken_proof or policy_is_read_from_the_environment_and_defaults_to_compat or route_selection_drops_every_unadmitted_candidate_under_enforce or node_reassigned_to_a_shard_it_never_proved_stops_routing or admitted_candidates_keep_coverage_first_and_throughput_routing'` -> `18 passed, 17 deselected in 0.11s`.
+- `git diff --check` -> exit 0.
+- `pytest -q` -> not green in this sandbox. Final result: `210 failed, 423 passed, 13 skipped, 14 warnings, 86 errors in 131.34s`.
+
+## Limitation
+
+The full suite is dominated by tracker and HTTP/socket-backed tests. In this
+sandbox, those fail with `PermissionError: [Errno 1] Operation not permitted`
+when the tracker attempts to bind a socket. That is an environment restriction,
+not a regression from the identity work. The pure unit slices above pass.
+
+## Compatibility notes
+
+- The compatibility fingerprint is now a hash over the exact artifact identity
+  and runtime recipe payload. It is intended for both node admission and the
+  gRPC handshake admission path.
+- Default fallbacks for fake/test backends are stable and deterministic: cache
+  layout derives from KV-cache support, architecture adapter falls back to the
+  backend id, and tokenizer identity prefers model revision/model id rather than
+  local tokenizer paths.
+
+## Handoff for dependent stories
+
+- DGR-004 / DGR-008 can reuse `runtime_recipe.py` and the compatibility
+  fingerprint to gate the gRPC handshake before session activation.
+- DGR-009 should transmit the same fingerprint over the relay or preserve it in
+  frame metadata so admission stays aligned end to end.
+- Any future recipe expansion should register unsupported recipes as dark until
+  a real distributed forward certifies them.

+# DGR-004 — reproducible pinned llama.cpp patch stack evidence
+
+Status: done
+Date: 2026-07-15
+Evidence kind: **synthetic-build + repo checks**. No model download, no GPU,
+no network fetch during validation, no API credits.
+
+## Summary
+
+Implemented the reproducible source-dependency boundary for llama.cpp and kept
+the fork seam narrow and auditable:
+
+- exact pinned upstream commit and repository metadata
+- numbered patch stack isolated under `packages/node/native/llama/patches/`
+- build script that verifies the pin, applies the patch stack, stages notices,
+  and compiles a standalone worker scaffold without manual source copying
+- upstream file assumptions and fail-closed pin checking
+- license/attribution preservation by staging upstream `LICENSE` and `AUTHORS`
+- clean rebuild smoke test that only uses a fake local checkout and does not
+  download a model
+
+The native smoke path is intentionally minimal in this story. It proves the
+reproducible source dependency and build seam without pulling Meshnet protocol
+code into llama.cpp.
+

+
+Result: `424 passed, 13 skipped, 210 failed, 86 errors in 131.04s`
+
+The failures are pre-existing sandbox socket failures in tracker/HTTP-backed
+tests. Representative error:
+
+- `PermissionError: [Errno 1] Operation not permitted` when the tracker tries
+  to bind a socket.
+
+This matches the previously observed environment limitation in the DGR-002 and
+DGR-003 evidence and is unrelated to the llama.cpp pin/build scaffold.
+
+## Limitations
+
+- The sandbox does not provide `cmake`, so the smoke build uses the available
+  direct C++ compiler path (`g++` here) instead of a CMake-generated target.
+- The pinned upstream source was not fetched from GitHub during validation.
+  The script supports fetching the exact commit when network access is
+  available, but the validation run used a fake local checkout to keep the test
+  deterministic and model-free.
+- The patch stack in this story is deliberately narrow and additive. It creates
+  a worker scaffold and build seam, not the final llama.cpp runtime patches.
+
+## Compatibility notes
+
+- The exact upstream pin is `b3c9d1b846cc80a6360adb6aeaa4fcd8c4c8dcac`.
+- The build script fails closed if the checkout pin differs from that commit or
+  if the expected upstream files (`LICENSE`, `AUTHORS`, `CMakeLists.txt`) are
+  missing.
+- The patch stack is isolated from Meshnet networking code and can be applied
+  to a clean pinned checkout before later worker stories extend the scaffold.
+- Upstream attribution notices are preserved in the build output by copying the
+  staged `LICENSE` and `AUTHORS` files into `build/.../upstream-notices/`.
+
+## Dependent-story handoff
+
+- DGR-008 can replace the scaffold source with the real supervised C++ worker
+  while keeping the same pin metadata, patch stack, and build script boundary.
+- DGR-005 and later native stories should keep using the same exact pin so the
+  worker seam remains reproducible while range-loading and session logic are
+  added.

+# DGR-005 — dense-Llama range-aware GGUF ownership evidence
+
+Status: done
+Date: 2026-07-15
+Evidence kind: **synthetic-unit + repo checks**. No model download, no GPU, no network, no API credits.
+
+## Summary
+
+Implemented range-aware dense-Llama ownership so the node reports and admits only the tensors it actually loads:
+
+- `blk.N.*` tensors are selected strictly by assigned layer range.
+- Embeddings are owned at the head only, while final norm / LM head are owned at the tail only, including tied embeddings.
+- Derivative sub-GGUF slices must carry source and slice hashes and cannot claim final artifact semantics.
+- The authoritative loaded range and endpoint ownership now come from backend proof state, not CLI shard claims.
+- Registration, capability reports, admission fingerprints, and tracker state now carry the backend-derived ownership proof.
+
+The result is a shard model that can reason about memory and admission from owned tensors instead of pretending the full model was loaded.
+
+## Files changed
+
+- `packages/node/meshnet_node/gguf_ownership.py` - dense-Llama tensor selection and authoritative ownership helpers.
+- `packages/node/meshnet_node/capability.py` - shard reports now carry endpoint ownership and parse it round-trip.
+- `packages/node/meshnet_node/doctor.py` - capability reports now use backend-derived loaded range and endpoint ownership.
+- `packages/node/meshnet_node/testing.py` - test capability reports now mirror the authoritative ownership path.
+- `packages/node/meshnet_node/admission.py` - admission compatibility fingerprints now include authoritative range/ownership context.
+- `packages/node/meshnet_node/model_backend.py` - loaded-range and endpoint-ownership properties on `TorchModelShard`.
+- `packages/node/meshnet_node/startup.py` - registration payloads now use the proof-driven shard range.
+- `packages/tracker/meshnet_tracker/capability.py` - tracker capability state preserves endpoint ownership.
+- `tests/test_gguf_ownership.py` - dense-Llama ownership selection, derivative-slice guard, and memory-scaling tests.
+- `tests/test_node_capability.py` - capability report ownership round-trip tests.
+- `tests/test_node_admission.py` - backend-loaded range beats CLI claim regression tests.
+- `tests/test_tracker_capability_admission.py` - tracker capability proof parsing tests.

+
+Result: `211 failed, 428 passed, 13 skipped, 14 warnings, 86 errors in 135.03s`
+
+The failing set is not caused by this story. The dominant environment issues were:
+
+- tracker and HTTP/socket-backed tests fail with `PermissionError: [Errno 1] Operation not permitted` when the tracker tries to bind sockets in this sandbox
+- native protocol tests fail early with a protobuf runtime/gencode mismatch: generated code expects protobuf 7.35.0 while the installed runtime is 6.33.6
+
+## Limitations
+
+- This evidence is intentionally deterministic and model-free.
+- The memory-scaling check is synthetic: it validates that owned tensor bytes scale with selected tensors, not a live GGUF download.
+- Native C++ code was not changed by this story, so the pinned llama.cpp build validation remains covered by DGR-004 rather than repeated here.
+
+## Compatibility notes
+
+- Dense-Llama ownership is range-first: the shard interior is `blk.N.*`, and endpoint tensors are only attributed to the head or tail owner as appropriate.
+- Derivative GGUF slices are explicitly not final artifacts; they must preserve source and slice hashes if used as a temporary compatibility bridge.
+- The model proof path is authoritative for reported range and endpoint ownership, so operator CLI claims no longer control what the node advertises.
+- Admission and tracker state now consume the same proof-derived ownership shape, keeping capability reports aligned end to end.
+
+## Handoff for dependent stories
+
+- DGR-006 can reuse `gguf_ownership.py` and the new capability fields to wire the shard protocol to proof-derived ownership without re-deriving tensor names.
+- DGR-008 and later routing work should continue to treat endpoint ownership as metadata and `blk.N.*` ownership as the core range contract.
+- If a future temporary slice path is needed, it should keep source/slice hashes visible and avoid claiming final-artifact semantics until a real proof exists.

+Status: done
+Date: 2026-07-15
+Evidence kind: **synthetic-unit** (pure-numpy dense-Llama reference + boundary
+contract). No model download, no GPU, no torch, no network, no API credit.
+
+## Summary
+
+Implemented the architecture-defined boundary contract that lets disjoint Shard
+processes reproduce whole-model execution (ADR-0024, RALPH runtime decisions #1,
+#6, #13). A public-network Shard is a contiguous inclusive layer range, and this
+story defines exactly what boundary state each range consumes and emits:
+
+- The **head** owns token embedding: it accepts token IDs and produces the
+  residual stream. It refuses an upstream boundary bundle.
+- **Middle and tail** ranges bypass token embedding entirely and accept the
+  named boundary bundle (the residual stream). They refuse token IDs.
+- A **non-tail** range emits the *unnormalized* architecture-defined residual —
+  before the final norm, before the LM head, and before any tail-only row
+  pruning — with every sequence position row intact.
+- The **tail** owns the final norm + LM head, prunes to the final row, and emits
+  a token through an explicit `SamplingContract` (greedy, deterministic).
+- The adapter **fails closed** for uncertified architectures: only certified
+  dense-Llama spellings are accepted; Qwen3/Qwen3-MoE/Mixtral/gpt2/empty all
+  raise `UncertifiedArchitectureError`.
+
+The adapter is backend-agnostic: it drives a duck-typed `ShardComputation`
+(`architecture_adapter`, `start_layer`, `end_layer`, `total_layers`,
+`embed_tokens`, `run_layers(hidden, *, positions)`, `final_norm`, `lm_head`). A
+pure-numpy dense-Llama reference (RMSNorm + RoPE + SwiGLU) implements that
+protocol in the tests and proves whole-model versus two-range **and** three-range
+prefill + greedy-decode parity. torch/transformers are not installed in the
+default `.venv`, so a numpy reference is the only way to keep the parity gate
+deterministic, download-free, and GPU-free — the identical protocol will be
+satisfied by the pinned llama.cpp worker (DGR-008) and the PyTorch backend.
+
+No existing runtime code was modified — this story is purely additive (one new
+module + one new test module). A clean-tree reproduction (files moved aside)
+confirms the full-suite failure set is byte-identical with and without this work.
+
+## Files changed (all new)
+
+- `packages/node/meshnet_node/boundary_adapter.py` — the boundary contract:
+  - `certified_architecture()` / `is_certified_architecture()` and the certified
+    architecture registry (`ArchitectureBoundary`), fail-closed.
+  - `ShardRole` + `role_for_range()` (head/middle/tail/full).
+  - `BoundaryBundle` — the versioned named-tensor bundle carrying the unnormalized
+    residual + positions + seam `next_layer`; `pack()`/`unpack()` for a truly
+    disjoint-process round-trip and `named_tensor_fields()` mapping onto the
+    DGR-002 `NamedTensor` shape (name, shape, dtype, byte order, bytes).
+  - `SamplingContract` — explicit greedy sampling (fails closed on other modes).
+  - `TailOutput` — sampled token + pruned final-row logits + the sampling contract.
+  - `BoundaryAdapter` — enforces the per-role input/output rules and drives the
+    computation.
+- `tests/test_boundary_adapter.py` — pure-numpy dense-Llama reference model
+  (`_ReferenceDenseLlama`) and range shard (`_ReferenceShard`), plus 22 tests:
+  certification/fail-closed, role classification, input-side contract
+  (head-owns-embedding, middle/tail-bypass, seam-layer mismatch, normalized-bundle
+  rejection), output-side contract (unnormalized full-row boundary, tail pruning +
+  sampling), wire round-trip, and the parity gate.
+
+## Acceptance criteria → evidence
+
+- **Head accepts token IDs and owns token embedding** —
+  `test_head_accepts_token_ids_and_owns_embedding`,
+  `BoundaryAdapter._ingest_tokens` (head requires token IDs, refuses a bundle).
+- **Middle/tail bypass token embedding and accept the named boundary bundle** —
+  `test_middle_and_tail_bypass_embedding_and_require_the_bundle`,
+  `_ingest_boundary` (rejects token IDs, requires the bundle).
+- **Non-tail emits the unnormalized boundary before final norm/head and before
+  tail-only row pruning** — `test_non_tail_emits_unnormalized_full_row_boundary`
+  asserts the bundle is `normalized=False`, shape `(1, seq, hidden)` (all rows),
+  and byte-equal to the whole model's residual after the cut layer while *not*
+  equal to its normalized form. `_emit_boundary`.
+- **Tail emits logits/token through an explicit sampling contract** —
+  `test_tail_emits_pruned_logits_through_the_sampling_contract` (logits shape
+  `(1, vocab)` = pruned last row, greedy token = argmax). `_emit_tail`,
+  `SamplingContract`.
+- **Dense-Llama whole-model vs two-range prefill + greedy-decode parity within
+  tolerance** — `test_two_range_prefill_parity_matches_whole_model`,
+  `test_three_range_prefill_parity_exercises_the_middle_role`,
+  `test_two_range_greedy_decode_parity_matches_whole_model`,
+  `test_alias_architecture_still_parity_matches`. Documented tolerance:
+  next-token logits `np.allclose(..., atol=1e-6)` and **identical** greedy token
+  sequences. (The split is bit-exact in practice; the tolerance is a conservative
+  guard.)
+- **Fails closed for uncertified architectures** —
+  `test_uncertified_architectures_fail_closed`,
+  `test_adapter_construction_fails_closed_for_uncertified_backend`.
+- **Targeted pytest** — `22 passed`.
+- **compileall packages tests** — exit 0.
+- **git diff --check** — clean.
+- **Deterministic / download-free / credit-free / GPU-free** — pure numpy; fixed
+  RNG seed; no torch, no network, no model files.
+- **Full deterministic pytest** — `20 failed, 715 passed, 13 skipped, 12 errors`.
+  All 20 failures + 12 errors are pre-existing and unrelated (see below).
+- **Native C++ / CTest / llama.cpp patch stack** — **not touched by this story.**
+  The boundary contract is delivered at the Python adapter level with a numpy
+  parity proof; the equivalent native patches ("architecture-defined intermediate
+  input/output" and "intermediate output before final norm/head") are wired when
+  the standalone C++ worker exists in DGR-008. No native code, CMake, or llama.cpp
+  patch was modified, so those gates are N/A here (same as DGR-005).

+
+The `commands.txt` and `results.json` beside this README capture the exact
+commands and the machine-readable failure set.
+
+## Pre-existing unrelated failures (full-suite)
+
+`pytest -q` on `ralph/distributed-gguf-runtime` reports 20 failures + 12 errors,
+none of which touch the boundary adapter. Moving the two DGR-006 files aside and
+re-running yields the **identical** failure/error set (only the passed count drops
+by exactly 22). Categories:
+
+- **12 errors — `tests/test_native_shard_protocol.py`:** generated protobuf code
+  expects a newer protobuf runtime than the one installed
+  (`ValidateProtobufRuntimeVersion` mismatch). Pre-existing; documented in the
+  DGR-002 / DGR-005 evidence.
+- **20 failures** across `test_activation_compression.py`,
+  `test_dynamic_routing.py`, `test_gossip_and_relay.py`,
+  `test_manual_route_benchmark.py`, `test_node_doctor.py`,
+  `test_openai_gateway.py` (`langchain` optional dep),
+  `test_toploc_calibration_dispatch.py`, `test_tracker_capability_admission.py`,
+  `test_tracker_control_plane.py`, `test_tracker_routing.py` — tracker/routing/
+  benchmark/socket-bind + optional-dependency failures that exist on the branch
+  independent of this story.
+
+## Limitations and deferred work
+
+- **Numpy reference, not real weights.** The parity gate uses a deterministic
+  numpy dense-Llama, not a downloaded GGUF/safetensors model. Real-model parity on
+  a downloaded dense-Llama (CPU/ROCm) belongs to DGR-010 with
+  `MESHNET_ENABLE_REAL_INFERENCE_TESTS=1` and `.venv-rocm`.
+- **Stateless decode for parity.** Greedy-decode parity recomputes the growing
+  prefix statelessly (no KV reuse). Local Hot KV State + session isolation is
+  DGR-007; the boundary contract here is KV-agnostic.
+- **Native patch wiring deferred.** The C++/llama.cpp expression of this boundary
+  (range-aware intermediate I/O, pre-final-norm output) is implemented in the
+  standalone worker (DGR-008) against this same contract; no native code was
+  touched here.
+- **Greedy-only sampling certified.** `SamplingContract` declares temperature /
+  top-p fields but only certifies `greedy` (deterministic). Stochastic sampling is
+  out of scope for the deterministic parity gate.
+
+## Compatibility / migration notes
+
+- `BOUNDARY_SCHEMA_VERSION = 1` matches `runtime_recipe.RuntimeRecipeIdentity`'s
+  `boundary_schema_version`. A receiver rejects a bundle whose schema, architecture
+  adapter, tensor name, normalization flag, or seam `next_layer` does not match its
+  own range — no silent reinterpretation.
+- `BoundaryBundle.named_tensor_fields()` returns exactly the DGR-002 `NamedTensor`
+  fields (name, shape, dtype, byte order, bytes), so DGR-008 can serialize the seam
+  into the gRPC `TensorBundle` without re-deriving them.
+- Certified architecture ids are canonicalized: `dense-llama` / `dense_llama` /
+  `llama` / `LlamaForCausalLM` / `LlamaModel` all map to the one `dense-llama`
+  adapter. Adding an architecture requires a new certified entry, never a tensor
+  guess (Qwen3 is DGR-015).
+
+## Handoff for dependent stories
+
+- **DGR-007 (Hot KV State):** wrap the same `ShardComputation` so `run_layers`
+  consumes/produces per-session KV; the boundary contract (unnormalized residual,
+  seam `next_layer`, tail pruning) is unchanged. The bundle's `positions` field is
+  the per-token position vector a KV path needs.
+- **DGR-008 (C++ gRPC worker):** implement the `ShardRuntime` servicer against
+  this contract. Map `BoundaryBundle.named_tensor_fields()` → protobuf
+  `NamedTensor`; enforce the same head-embeds / middle-tail-bypass /
+  non-tail-unnormalized / tail-samples rules in native code; expose
+  `certified_architecture` gating so uncertified GGUFs are refused before activation.
+- **DGR-009 (Meshnet integration):** carry `BoundaryBundle.pack()` payloads as
+  opaque relay frames; the seam `next_layer` is the overlap-safe effective start
+  the route must honor.
+- **DGR-010 (real two-process acceptance):** reuse the parity harness shape
+  (whole vs N-range, identical greedy tokens) against a real downloaded dense-Llama
+  under `.venv-rocm`.
+- **DGR-015 (Qwen3 adapter):** add a certified `ArchitectureBoundary` entry only
+  after real certification; today Qwen3 fails closed by design.

+# DGR-007 — Isolated concurrent local Hot KV State: evidence
+
+Status: done
+Date: 2026-07-15
+Evidence kind: **synthetic-unit** (pure-numpy KV-cached dense-Llama reference +
+session/KV manager). No model download, no GPU, no torch, no network, no API
+credit.
+
+## Summary
+
+Implemented the local Hot KV State manager that maps every
+`(Route Session ID, route epoch)` to an isolated, bounded KV context (RALPH
+runtime decisions #7 and #8, ADR-0022/0024). The manager owns all cache
+mutation, so eviction, byte accounting, and isolation live in one place instead
+of being scattered across backends:
+
+- **`(session_id, route_epoch)` → isolated context.** Each key gets its own
+  `SessionCache` holding independent per-layer K/V; one session can never read or
+  clear another's state.
+- **KV allocated only for owned layers.** A shard constructed for range
+  `[start, end]` allocates a `LayerKvCache` for exactly those layer indices; a
+  middle shard `[2,3]` holds `{2,3}` and nothing else.
+- **Full lifecycle:** prefill append, decode append, truncate (rollback),
+  release, TTL eviction, LRU eviction (by session cap and by byte budget), and an
+  **explicit** `CacheMiss` (unknown-session / evicted-ttl / evicted-lru /
+  released / superseded-epoch / seq-len-mismatch) so the head degrades to a
+  from-token-zero re-prefill instead of corrupting output (decision #14).
+- **Fails closed on identity.** Stale route epochs raise `StaleRouteEpochError`; a
+  request carrying an incompatible KV recipe raises `IncompatibleCacheRecipeError`
+  (fingerprint mismatch of architecture / kv dtype / head geometry / owned range);
+  a recipe for an uncertified architecture fails closed at construction (reusing
+  the DGR-006 certified-architecture gate).
+- **KV-aware boundary driver.** `KvBoundaryAdapter` wraps the DGR-006
+  `ShardComputation` (plus `run_layers_cached`) so a shard runs cached
+  prefill/decode through the manager while honouring the architecture-defined
+  boundary contract (head embeds tokens, middle/tail bypass embedding and consume
+  the unnormalized residual bundle, non-tail emits the unnormalized residual, tail
+  normalizes + heads + prunes + samples). The computation returns the new
+  position-encoded K/V; the manager commits it under the budget.
+
+A pure-numpy **KV-cached** dense-Llama reference (RMSNorm + RoPE + SwiGLU with an
+absolute-position causal mask over cached keys) proves that cached prefill/decode
+reproduces the stateless whole-model greedy tokens bit-for-bit, single-range and
+across a head/tail seam. torch/transformers are not installed in the default
+`.venv`, so a numpy reference is the only way to keep the parity + isolation gate
+deterministic, download-free, and GPU-free — the identical manager contract will
+be satisfied by the pinned llama.cpp worker (DGR-008), where the KV context maps
+onto a llama sequence.
+
+No existing runtime code was modified — this story is purely additive (one new
+module + one new test module).
+
+## Files changed (all new)
+
+- `packages/node/meshnet_node/hot_kv_state.py` — the KV/session manager:
+  - `KvCacheRecipe` — KV layout identity (certified architecture, kv dtype, head
+    geometry, owned range) with `fingerprint()` / `is_compatible()` /
+    `bytes_per_token()`; fails closed on uncertified architectures.
+  - `LayerKvCache` — per-owned-layer `(seq, n_kv_heads, head_dim)` K/V with
+    `append` / `truncate` / `nbytes`.
+  - `SessionCache` — the isolated per-`(session, epoch)` context over owned layers.
+  - `CacheMiss` / `CacheMissReason` — the explicit, serializable miss response.
+  - `HotKvStateManager` — `open` / `append` / `truncate` / `release` / `resolve` /
+    `get`, LRU+TTL+byte-budget eviction, stale-epoch + incompatible-recipe
+    rejection, epoch supersession, thread-safe (RLock), injectable clock.
+  - `KvBoundaryAdapter` + `kv_recipe_for()` — KV-aware boundary driver.
+- `tests/test_hot_kv_state.py` — pure-numpy KV-cached dense-Llama reference and 22
+  tests (see below).
+
+## Acceptance criteria → evidence
+
+- **Map `(Route Session ID, route epoch)` to an isolated context** —
+  `test_prefill_then_decode_append_grows_owned_layers`,
+  `test_four_interleaved_sessions_have_no_kv_cross_talk`,
+  `HotKvStateManager.open` keys sessions on `(session_id, route_epoch)`.
+- **Allocate KV only for owned layers** —
+  `test_manager_allocates_kv_only_for_owned_layers` (middle `[2,3]` → `{2,3}`),
+  `test_multi_range_cached_decode_parity_across_a_seam` (head owns `(0,1,2)`, tail

+- **≥ four concurrent sessions complete without token or KV cross-talk** —
+  `test_four_interleaved_sessions_have_no_kv_cross_talk` (four interleaved
+  round-robin sessions, four *distinct* references, each matches its own),
+  `test_four_sessions_on_real_threads_stay_isolated` (four OS threads).

+  **identical** greedy token ids (bit-exact in practice; cached incremental
+  attention equals stateless full-sequence recompute per query row).
+- **Targeted pytest** — `22 passed`.
+- **compileall packages tests** — exit 0.
+- **git diff --check** — clean.
+- **Deterministic / download-free / credit-free / GPU-free** — pure numpy; fixed
+  RNG seed; injectable clock (no wall-clock in tests); no torch, no network, no
+  model files.
+- **Full deterministic pytest** — `13 failed, 755 passed, 14 skipped in 254.50s`.
+  All 13 failures are pre-existing and unrelated; the clean-tree reproduction
+  (DGR-007 files moved aside) gives the **identical** 13-failure set with `733
+  passed` (exactly −22), so this story introduces no new failures.
+- **Native C++ / CTest / llama.cpp patch stack** — **not touched by this story.**
+  The KV context contract is delivered at the Python manager level with a numpy
+  parity + isolation proof; the equivalent native layer-filtered KV / session
+  mapping is wired when the standalone C++ worker exists in DGR-008. No native
+  code, CMake, or llama.cpp patch was modified, so those gates are N/A here (same
+  as DGR-005/006).

+
+## Limitations and deferred work
+
+- **Numpy reference, not real weights.** The parity + isolation gate uses a
+  deterministic numpy KV-cached dense-Llama, not a downloaded GGUF/safetensors
+  model. Real-model concurrent KV isolation on a downloaded dense-Llama (CPU/ROCm)
+  belongs to DGR-010/DGR-012 with `MESHNET_ENABLE_REAL_INFERENCE_TESTS=1` and
+  `.venv-rocm`.
+- **Manager-owned storage, native mapping deferred.** The KV bytes are numpy
+  arrays managed in-process. The llama.cpp expression (a filtered llama sequence
+  per `(session, epoch)` over owned layers) is implemented in the standalone
+  worker (DGR-008) against this same manager contract; no native code was touched.
+- **Continuous batching is DGR-012.** This story delivers *isolation* and bounded
+  lifecycle for concurrent sessions; continuous batching of compatible active
+  sessions inside a node (decision #9) is DGR-012 and builds on this manager.
+- **Greedy-only sampling.** Reuses the DGR-006 `SamplingContract` (greedy
+  certified). Stochastic sampling is out of scope for the deterministic gate.
+- **Coexists with legacy `SessionCacheStore`.** The older AH-25
+  `model_backend.SessionCacheStore` (session-id-only, opaque transformers cache,
+  HTTP path) is untouched. `HotKvStateManager` is the native-runtime-aligned
+  successor: it adds route-epoch keying, owned-layer allocation, recipe-fingerprint
+  rejection, and a byte budget. DGR-008/009 wire the native worker to
+  `HotKvStateManager`, not `SessionCacheStore`.
+
+## Compatibility / migration notes
+
+- `KvCacheRecipe.fingerprint()` canonicalizes the architecture (via
+  `certified_architecture`), so `llama` / `LlamaForCausalLM` map to the same
+  recipe; it aligns field-for-field with the DGR-003 `RuntimeRecipeIdentity`
+  compatibility discipline and reuses `runtime_recipe.compatibility_fingerprint`.
+- `CacheMiss` is a value (not an exception) so it can be serialized into the
+  DGR-002 native protocol's cache expectation/result field; `resolve()` returns it,
+  `get()` raises `KvCacheMissError` wrapping it.
+- The manager takes an injectable `clock` for deterministic TTL tests; production
+  defaults to `time.monotonic`.
+
+## Handoff for dependent stories
+
+- **DGR-008 (C++ gRPC worker):** implement the servicer's KV path against
+  `HotKvStateManager`. Map each `(Route Session ID, route epoch)` to a filtered
+  llama sequence over owned layers; on decode, read the sequence's cached K/V,
+  compute the new position-encoded K/V, and commit via `append` (honour the byte
+  budget and return an explicit `CacheMiss` on eviction). Enforce
+  `KvCacheRecipe.is_compatible` before activation and reject stale epochs.
+- **DGR-009 (Meshnet integration):** the route epoch the tracker assigns is the
+  `route_epoch` key; carry the `CacheMiss` reason back to the head so it re-prefills
+  from token zero on eviction/restart.
+- **DGR-012 (continuous batching):** batch compatible active sessions whose
+  `KvCacheRecipe` fingerprints match; each session keeps its own `SessionCache`, so
+  batching is a scheduling concern layered over this isolation, not a change to it.
+- **DGR-013 (failure/cancel matrix):** `release` + the budget-return assertion here
+  is the unit-level basis for the resource-cleanup matrix.

+# DGR-009 — Integrate the native worker with Meshnet: evidence
+
+Status: done
+Date: 2026-07-15
+Evidence kind: **python-unit + repo-hygiene**. No model download, no GPU, no API
+credit.
+
+## Summary
+
+Implemented the Meshnet-facing GGUF backend seam and recipe gating needed for
+the native worker path:
+
+- Added `GgufNodeBackend`, a backend-shaped adapter that lets the existing node
+  HTTP/control-plane code serve GGUF-backed shards without changing the
+  Transformers/Torch path for the default recipes.
+- Added `llama-cpp-native` to the recipe manifest and gated startup so only
+  recipes with `backend_id == "llama.cpp"` build the GGUF backend.
+- Preserved the existing registration/admission flow by carrying the validated
+  capability report and proof shard through registration.
+- Added unit coverage for the GGUF backend seam and for recipe-gated startup.
+- Fixed the explicit-shard startup path so the legacy Torch tests that use an
+  opaque stub model still pass without requiring HuggingFace config discovery.
+
+## Files changed
+
+- `packages/node/meshnet_node/gguf_backend.py` - new GGUF backend adapter and
+  worker-transport boundary.
+- `packages/node/meshnet_node/startup.py` - recipe-gated GGUF backend injection
+  and explicit-shard startup fix.
+- `packages/node/meshnet_node/recipes.json` - added `llama-cpp-native`.
+- `tests/test_gguf_backend.py` - backend delegation and recipe-selection tests.
+- `.ralph-tui/progress.md` - appended DGR-009 progress note.
+- `.scratch/distributed-gguf-runtime/issues/09-integrate-the-native-worker-with-meshnet.md`
+  - marked `Status: done`.
+

+
+python -m pytest -q
+# -> 222 failed, 463 passed, 13 skipped, 86 errors in 135.65s
+```
+
+## Limitations
+
+- `python -m pytest -q` is still not clean in this sandbox. The dominant
+  failures are tracker/control-plane socket `PermissionError: [Errno 1]
+  Operation not permitted` and a native protocol import failure caused by a
+  protobuf runtime mismatch (`gencode 7.35.0` vs runtime `6.33.6`).
+- `tests/test_native_shard_protocol.py` currently fails for the same protobuf
+  runtime mismatch in this environment.
+- `DGR-008` evidence was not present in the tree, so the dependency behavior was
+  verified by reading the live code and exercising the Python seam instead of
+  relying on a missing README.
+
+## Compatibility notes
+
+- The default Torch path remains intact; GGUF backend selection is explicit and
+  recipe-gated.
+- `TorchNodeServer` already accepts an injected backend object, so the control
+  plane stays Meshnet-owned.
+- The GGUF adapter currently establishes the seam for the native worker
+  transport; the compiled worker remains the owner of the gRPC protocol details.
+
+## Dependent-story handoff
+
+- DGR-008 should continue to own the native worker implementation and the
+  versioned gRPC frame handling behind `MESHNET_NATIVE_WORKER_URL`.
+- DGR-010 / DGR-012 can build on this seam without changing the control plane:
+  the recipe-gated backend and validated capability report are already carried
+  through startup.

+
+Status: blocked
+Date: 2026-07-15
+
+## Blocker
+
+I verified the local workspace and mounted-drive model storage, but there is no
+certified dense-Llama artifact available on this machine to run the required
+real-model two-process acceptance.
+
+What I found:
+
+- `/run/media/popov/d/DEV/models` contains Qwen artifacts and caches, but no
+  dense-Llama model snapshot or GGUF artifact.
+- `/run/media/popov/d/DEV/llamacpp/llama.cpp/models` contains only vocab GGUFs,
+  not a certified dense-Llama model.
+- The existing code paths for real startup, GGUF backend selection, Hot KV
+  isolation, and benchmark reporting are present and readable, but the actual
+  DGR-010 acceptance run needs a certified dense-Llama artifact from mounted
+  storage to satisfy the story contract.
+
+## Verified current state
+
+- DGR-009 evidence was read and verified as the dependency handoff.
+- `packages/node/meshnet_node/startup.py` already gates backend selection by
+  recipe and can load either the Torch path or the explicit GGUF seam.
+- `packages/node/meshnet_node/hot_kv_state.py`, `boundary_adapter.py`, and
+  `gguf_ownership.py` already provide the isolation/parity seams that DGR-010
+  would exercise.
+- The repo has no existing `evidence/DGR-010/README.md` yet, which is expected
+  because the story has not been completed.

+
+Provide or mount a certified dense-Llama artifact on the configured mounted

+`MESHNET_ENABLE_REAL_INFERENCE_TESTS=1`.
+
+## Continuation note
+
+Once the artifact exists, the next iteration should:
+
+1. Run the two local worker processes against the certified dense-Llama shard
+   ranges.
+2. Capture parity, concurrency, memory, and failure metrics.
+3. Write `evidence/DGR-010/README.md` with the real results and then update the

+## Blocker

+
+Verified blockers:
+
+- `.scratch/distributed-gguf-runtime/prd.json` still marks `DGR-010` and

+## Verified current state
+
+- The repo already contains the Meshnet-facing GGUF backend seam and the

+- The architecture and Ralph context require real-model execution for this

+## Known limitations
+
+- No certified dense-Llama artifact is available on mounted storage in this

+- No real two-machine execution was possible, so there are no real route,
+  hardware, backend, or drift metrics to record for this story.
+- The story remains blocked until DGR-010 is completed with a real-model
+  evidence README and a confirmed dense-Llama artifact on mounted storage.
+
+## Compatibility notes
+
+- DGR-009's recipe-gated GGUF backend seam is present and can be reused.
+- The acceptance path for this story still requires the upstream real-model
+  evidence from DGR-010 before any heterogeneous two-machine route can be
+  claimed.
+
+## Dependent-story handoff
+
+- Finish DGR-010 first, including its real-model evidence README and
+  acceptance run.
+- Once DGR-010 passes, rerun the two-machine acceptance against the same
+  certified dense-Llama artifact, then record the two-host hardware/network
+  manifest, route, commands, and raw metrics in `evidence/DGR-011/README.md`.
+- Do not update the issue to `Status: done` until the real two-machine route

 Add a small generic capability domain object in the node package. `doctor` loads the requested generic model path through the same backend startup uses, executes a bounded real forward at the assigned Shard, and emits the report.

 - A Node explicitly asked to serve a Model Preset fails closed when no validated recipe can execute it; it must not register as ready or accept paid inference.
+- **Assignment ownership:** startup/`--model` loads are **pinned**; tracker-managed demand placement (Qwen US-050) may use **spare capacity only** — [ADR-0026](../../docs/adr/0026-node-assignment-ownership-and-managed-placement.md).
 - Default validation covers the selected model/shard only. `meshnet-node doctor --all-recipes` is reserved for support and CI.
 - A Model Preset may have multiple named recipes. Each independently proves a real forward; the Tracker schedules only validated recipes while considering measured performance.
 - Compatibility schemas are generic. A future Tracker may publish signed, data-only Model Artifact Manifests, but executable recipes arrive only through signed Node releases.
