--- RAW OUTPUT ---
I’m pulling the story context first: `RALPH-CONTEXT.md`, the DGR-003 issue, the progress log, and the DGR-002 evidence trail so I can verify the existing shape before changing anything. After that I’ll inspect the implementation surface, then patch only the files needed for this story and run the deterministic checks.
I’ve started the context sweep and I’m now checking the story’s own dependency trail, not just the ticket text, so I can tell whether DGR-003 is already effectively done or needs code changes. Next I’m reading the progress log and the prerequisite evidence README(s), then I’ll map the implementation surface.

I have the repo-level memory now. The key question is whether identity handling already exists in the code path or whether this story needs a new compatibility fingerprint and stricter admission checks; I’m reading the route/handshake docs and the prerequisite evidence next to answer that concretely.

The prerequisite schema story is done and already points at the exact handoff: `ArtifactFingerprint` exists in the protobuf contract, but DGR-003 is responsible for making it semantically exact and enforced. I’m checking the live code now to see how much of that plumbing already exists before I patch anything.

The architecture docs are clear: this story should not add a new transport or backend, only tighten identity and admission. I’m now checking whether the repo already has a runtime-recipe module or if the logic still lives inside tracker/node capability structures that need refactoring.

The current code has enough hooks for a stronger identity model, but the fingerprint is not yet threaded through startup registration.

I’ve mapped the live seams. The change is broader than one function, so I’m switching to an implementation plan: add a first-class runtime-recipe identity module, thread its fingerprint through node proof, tracker admission, and registration payloads, then update the focused tests and evidence notes around that contract.
I’m writing the new recipe-identity module first so the rest of the patch can consume one cohesive source of truth instead of scattering hashes and dtype rules across node and tracker code. After that I’ll wire it into the proof, admission, and registration paths.
The proof object now has the richer identity shape. I’m wiring the node admission gate to require the exact compatibility fingerprint, not just the older model/shard/recipe tuple, so a recipe or cache-layout drift fails closed before registration.
I’ve got the proof object and node admission using the new fingerprint. The next step is to make the tracker see the same declared fingerprint at registration time so it can keep unsupported recipes dark instead of treating the proof as self-contained.

[shell] $ /bin/bash -lc "sed -n '470,540p' packages/tracker/meshnet_tracker/capability.py"
The tracker parser is now expecting the runtime recipe to carry its own fingerprint, so I’m making that fingerprint part of the runtime-recipe object itself instead of only a report-side property. That keeps the wire shape self-describing and lets the tracker compare the exact cached proof.
[shell] $ /bin/bash -lc "sed -n '790,840p' packages/tracker/meshnet_tracker/server.py"
[shell] $ /bin/bash -lc "sed -n '840,885p' packages/tracker/meshnet_tracker/server.py"

[shell] $ /bin/bash -lc "sed -n '740,790p' packages/tracker/meshnet_tracker/server.py"
I’m updating the focused tests now. The old identity assertions assumed a much smaller report shape, so I’m making the test fixtures produce the new nested artifact/runtime-recipe fields and matching compatibility fingerprints instead of loosening the assertions.
[shell] $ /bin/bash -lc "sed -n '1,120p' packages/node/meshnet_node/testing.py"
[shell] $ /bin/bash -lc "sed -n '120,220p' packages/node/meshnet_node/testing.py"

[shell] $ /bin/bash -lc "sed -n '1,120p' packages/tracker/meshnet_tracker/server.py"
I caught a subtle mismatch before running tests: the report fingerprint includes the model config fingerprint, so the admission-side expected fingerprint has to include the same value. I’m fixing that now so the node and tracker compute the exact same digest rather than two almost-identical ones.
I’m tightening one last edge: the declared compatibility fingerprint should be a real string, not an empty placeholder, otherwise a malformed registration could slide through as “unset.” That keeps the tracker fail-closed on the new field too.
I’m aligning one more field before verification: on GPU hosts the node report includes the actual device name, so the admission-side expected fingerprint has to include the same value or it will diverge. I’m adding the same device-name derivation here rather than assuming CPU-only behavior.
[shell] $ /bin/bash -lc "rg -n 'recipe_id.*recipe_version|capability_report|downloaded_models' tests/test_node...
[shell] $ /bin/bash -lc "rg -n 'set\\(captured_registration|set\\(payload\\)|compatibility_fingerprint|capabil...
Another mismatch surfaced while comparing the proof hash: the report fingerprint also includes the runtime versions map, so the test seam has to populate that instead of leaving it empty. I’m fixing the test helper now so the node-side admission and tracker-side checks see the same runtime evidence.
I’m adding one final self-consistency check on the node-side report parser: if a serialized capability report carries a top-level compatibility fingerprint, we should verify it matches the nested fields instead of trusting the wrapper blindly. That keeps the report object fail-closed even before admission runs.

[shell] $ /bin/bash -lc "sed -n '450,520p' packages/node/meshnet_node/capability.py"
I’m normalizing one field that could have leaked a machine-local path into the fingerprint: tokenizer revision should be stable across nodes, so I’m preferring the model revision or model id instead of `name_or_path`. That keeps the fingerprint routable rather than host-specific.
I’ve got the identity plumbing in place; next I’m tightening the unstable bits, then I’ll run the targeted checks and write the evidence/progress updates.

[shell] $ /bin/bash -lc "sed -n '1,260p' packages/tracker/meshnet_tracker/capability.py"
I’m checking the fingerprint construction and the report serialization end-to-end now. The main thing I’m looking for is accidental dependence on local paths or other unstable values.

[shell] $ /bin/bash -lc "sed -n '240,360p' packages/node/meshnet_node/admission.py"
The one unstable field I found is tokenizer identity: it still falls back to a local tokenizer path. I’m switching that to the model revision / selection model id so the fingerprint stays portable across machines.
[shell] $ /bin/bash -lc "sed -n '604,626p' packages/node/meshnet_node/doctor.py"

[shell] $ /bin/bash -lc "sed -n '520,760p' packages/node/meshnet_node/capability.py"
I found a real formatting bug in the capability builder, plus one more tokenizer fallback in the admission fingerprint path. I’m fixing both before I run the test slices.
The code path is stable enough for verification now. I’m running compileall first so syntax problems surface before the pytest slices.
[shell] $ /bin/bash -lc 'python -m compileall packages tests'
Compileall passed. I’m running the story-scoped tests next to check the new identity shape, admission fail-closed behavior, and tracker parsing.

Two failures are structural, not logic regressions: admission is missing its runtime-version helper, and report construction is computing derived identities before it validates the base fields. I’m reordering that path and adding the missing helper now.

The remaining mismatch is in the default architecture adapter. The test helper and the admission path disagree on what to use when the backend has no config, so I’m making that fallback explicit and shared.

I need the exact divergence, so I’m comparing the fingerprint payloads directly instead of guessing from the symptoms. That should show which field is still unstable.

The fingerprint split is narrower than it first looked: the test helper was defaulting `kv_layout` to `session-cache` while admission derived `stateless` for the same fake backend. I’m making the helper derive KV layout the same way admission does.
I’ve synchronized the test-only report builder with the admission-side KV layout rule. Re-running the node admission slice to confirm the fingerprints now line up.
[shell] $ /bin/bash -lc 'pytest -q tests/test_node_admission.py'
The node-side slices are green now. I’m checking the tracker test file for a non-socket subset so I can still validate the admission logic there without tripping the sandbox’s socket restriction.

One tracker case still slipped in because it starts the HTTP server. I’m rerunning a clean pure-function subset that avoids the socket-backed paths entirely.

The implementation itself is green on the focused slices. I’m doing the final hygiene pass now: syntax/diff checks, then I’ll write the evidence note and progress entry in the repo’s expected format.

I have the story-scoped checks green. I’m doing one full-suite pass now so the evidence file can record the exact unrelated failure mode instead of leaving it implied.
[shell] $ /bin/bash -lc 'pytest -q'
The full suite is still running and already showing the same mixed failure profile as the branch baseline, with socket-backed tracker cases in the stream. I’m waiting for the final count so the evidence note can name it precisely.

The full suite is not clean in this sandbox: most failures are tracker/network tests trying to open sockets, which the environment blocks. I’ve got enough to write the story evidence now, including the exact counts and the worktree files I changed.

[shell] $ /bin/bash -lc 'git diff --stat'
I’m writing the durable handoff now: one evidence note, one progress entry, and the issue status flip once the documentation is in place.
The handoff files are in place. I’m doing one last cleanliness check on the final diff, then I’ll wrap with the concrete outcome and the tracker failure note.

Implemented exact artifact/runtime recipe identity and fail-closed admission for DGR-003.

- Added `packages/node/meshnet_node/runtime_recipe.py` with `ArtifactIdentity`, `RuntimeRecipeIdentity`, stable fingerprint helpers, and exact artifact binding.
- Plumbed `compatibility_fingerprint` through node capability reports, doctor/startup, tracker capability state, and tracker registration storage.
- Made admission fail closed on compatibility mismatches, including artifact, tokenizer, architecture, boundary schema, activation recipe, and cache layout drift.
- Kept the test helper aligned with production defaults so the same fingerprint is emitted and checked end to end.
- Wrote evidence at [`.scratch/distributed-gguf-runtime/evidence/DGR-003/README.md`](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/evidence/DGR-003/README.md), updated progress at [`.ralph-tui/progress.md`](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.ralph-tui/progress.md), and marked the story done in [the issue file](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/issues/03-define-exact-artifact-and-runtime-recipe-identity.md).

Verification:
- `python -m compileall packages tests`
- `pytest -q tests/test_node_capability.py` -> `48 passed`
- `pytest -q tests/test_node_admission.py` -> `20 passed`
- `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`
- `git diff --check` -> clean
- `pytest -q` -> not green in this sandbox; final result was `210 failed, 423 passed, 13 skipped, 14 warnings, 86 errors in 131.34s`, dominated by tracker/socket tests blocked by `PermissionError: [Errno 1] Operation not permitted`
