I read this as an independent read-only release-authority audit - I’ll inspect the transaction, rollback, evidence, and exact bindings, run the scoped tests once, then return one unconditional verdict with exact references.


The transaction model is now clear: an exclusive-lock transition WAL drives paired registry/ledger publication, promotion is N+1, rollback compensation is append-only N+2, and credentials are rebound only after chain verification. I’m moving to final binding checks and the single scoped test run.


The preseal verifier and immutable/exact-binding checks pass. The initial pytest process collected zero tests because the worktree’s profile package was not on `PYTHONPATH`; I’m correcting that invocation environment without touching authority and will treat the resulting scoped execution as the test evidence.


I read this as a completed independent read-only authority audit - I verified every requested property and found no blockers.

# UNCONDITIONAL PASS

`blocker_count=0`

Evidence:

- Paired WAL and interrupted registry/ledger recovery: `gateway/platforms/task26_runtime_authority.py:604-723`; adversarial tests `tests/test_nutricoach_v150_v15_authority_adversarial.py:103-147`.
- N/N+1/N+2 and append-only rollback via predecessor `qualify`, with no revoke: `scripts/nutricoach_v150_concrete_host.py:573-620,682-737`.
- Stale, revoked, and replay denial: `tests/test_nutricoach_v150_v15_authority_adversarial.py:86-100,220-248`.
- Credential publication interruptions: `tests/test_nutricoach_v150_v15_authority_adversarial.py:150-187`.
- Precommit and postcommit rollback: `tests/test_nutricoach_v150_v15_authority_adversarial.py:190-217`; controller boundary `scripts/nutricoach_v150_sealed_controller.py:94-151,238-252`.
- Predecessor production-loader restoration: `scripts/nutricoach_v150_concrete_host.py:720-737`; asserted with event count N+2 at adversarial test lines `182-185,200-203,212-215`.
- Exact package/candidate binding:
  - Package digest `cd4c2365...02d74`
  - Candidate digest `7c12fa19...a5ed9`
  - `scripts/verify_nutricoach_v150_preseal_v15.py:72-100`
  - `sealed-target.json` and `package-manifest.json`: 332/332 entries matched.
  - Controller closure: 320/320 entries matched.
  - Preseal tree: zero writable files, symlinks, or hardlinked files.
- Rehearsal: `report.json` status `PASS`, 13/13 cases passed, `external_events=0`, `live_source_unchanged=true`.
- Live authorization ledger, execution root, and successor runtime remain absent.

Verification:

- Preseal verifier: `V15_RUNTIME_AUTHORITY_PRESEAL_VERIFIED`.
- Scoped tests: `40 passed in 6.03s`.
