I read this as an independent, read-only closure audit of the exact r71 artifacts - I’ll discover the sealed receipt and verifier contract, rehash and execute only the prescribed offline checks, then write the requested JSON evidence with either PASS/blocker_count0 or exact blockers.


The sealed receipt resolves the artifact graph: candidate-r3 is the sole selection, the retained preflight root is an authenticated non-consumed dependency, and the canonical suite is five files totaling 62 tests. I’m now validating the verifier invocation contract and computing independent tree/package/closure hashes before executing anything.


All independent hash conventions now reproduce the receipt exactly: candidate-r3 is 362 files with tree digest `6310…dce9`, and preseal is 595 files with tree digest `a76a…7ee8`. I’m starting the read-only execution phase using the frozen Python 3.12 interpreter, an isolated external cwd, bytecode/cache suppression, and a harness constrained to the sealed controller source, candidate wheels, and dependency snapshot.


The first harness exposed a harness-order artifact, not a sealed test failure: eagerly importing wheel packages before pytest locked a partial `checkin_cli` package before the sealed test loader established its normal resolution order, yielding 47 pass/15 harness failures. No artifact or production hash changed. I’m rerunning once with the exact sealed suite contract—ambient `PYTHONPATH` cleared at process start, sealed paths injected without eager imports, then module origins captured after the 62-test run.


The required execution gates are now clean: both canonical verifiers pass, the exact sealed suite passes 62/62, and post-run application origins resolve only to the sealed candidate wheels/dependency snapshot (with controller scripts from the sealed closure). I’m completing the final consistency pass against every manifest entry, package binding, prewrite receipt, effect-root absence, and before/after production hash, then I’ll remove only this auditor’s temporary root and seal the requested evidence JSON.


The closure audit itself passed and the evidence was written, but cleanup hit test-created read-only directories inside the auditor-owned temp root. I’m normalizing permissions only within that disposable root, removing it, and validating the final JSON/hash; no sealed or production path is affected.


I read this as completing the independent r71 closure audit - the requested evidence is sealed and validated.

**PASS — blocker_count: 0**

Evidence:
`/home/cube/projects/richard/traning coach/.omo/evidence/nutricoach-telegram-checkin-stepper/task-9-audit-closure.json`

SHA-256: `c27eaa148c7551c5e4bfa3dd8b99fb9f16e5c7a3be4f5694b3ef5fed02602e60`

Verified:
- Candidate and canonical preseal verifiers PASS
- Exact sealed suite: 62 passed
- Frozen hashes, manifests, closure, package, rehearsal, and permission bindings consistent
- Authorization, execution, successor runtime, and observer absent
- Production hashes unchanged
- Only auditor temporary files removed
