I read this as a final read-only compliance audit of the exact Task26 delivered candidate - I’ll trace the pinned root, receipts, prefreeze/ledger evidence, and verifier outputs against every named clause, then return a strict PASS/FAIL/INCONCLUSIVE.


## Bottom line

**PASS** for the GOAL/CONSTRAINT lane on exact delivered candidate `d1109d8f…39112`. The candidate is internally consistent, directly reproducible offline, and clears every named historical blocker; this does not complete Task26, authorize Task27, or permit release/live activity.

## Action plan / audit disposition

1. **Provenance and seals — PASS**
   - Every hash referenced by ledger line 169 matched.
   - Direct delivered-root verifier: `TASK26_INDEPENDENT_CANDIDATE_PASS`.
   - Direct frozen bootstrap: `TASK26_FROZEN_BOOTSTRAP_PASS` and `ACTUAL_INSTALLED_GOLDEN_PATH_PASS`.
   - Delivered and receipt-root postfreeze seals are byte-identical: `3002d815…5878f6`.
   - Prefreeze has exactly 395 captured files with zero missing, extra, or digest mismatches.
   - Delivered root has zero writable paths, symlinks, or mode violations.

2. **Qualification and portability — PASS**
   - Profile receipt v2 records actual Python 3.12.9 execution: 749 collected, executed, and passed; exit 0.
   - Hermetic Ty 0.0.21 targeted Python 3.12 exactly.
   - All 809 diagnostics are outside the declared transport/capability spans; independently measured span overlap is zero.
   - `direct_url` portable projection v2 and two-root installation parity pass.

3. **Authority paths — PASS**
   - Complete-update ingress lease is installed before PTB dispatch.
   - Background recovery, generation, and scheduled transport use the shared external authority lease.
   - Capability issuance and provider transport are separately lease-fenced.
   - Race evidence proves revocation-first causes zero mutation/send, operation-first blocks revocation until completion, and cancellation releases the lease.
   - Protected controller path is used; no alternate issuance path is evidenced.
   - Watcher is event-driven `dnotify_signalfd_v1`, one directory resource, zero inotify.
   - Advisory provider requests use `store=false`.
   - Real local HTTP socket evidence records post-revocation server delivery but zero handler entries and mutations, followed by complete watcher/socket cleanup.

4. **Seven Task26 clauses — PASS in source and installed modes**
   - All 22 natural-language answers canonicalized once with zero re-asks.
   - Deterministic ambiguity targets field 21; stale field-zero revision is rejected.
   - Preview cannot satisfy production acceptance.
   - Approved-card projection failure prevents capability issuance.
   - Unknown provider outcome consumes authority and is not retried.
   - Successful lifecycle has one transport call, one `sent_audited` row, one surface receipt, and duplicate rejection.
   - Cleanup resumes from `copied_verified` to one committed terminal receipt.

5. **Final state and scope — PASS**
   - Generation lineage contains the seven required states through `sent_audited`.
   - Archive contains 33 verified artifacts and a seven-record generation projection.
   - Customer is disabled, nonconsenting, paused, and terminal with zero active, pending, unknown, or orphan work.
   - Both runtime wheels contain zero trainer tokens.
   - Ledger ends at line 169 with Task26 pending review; no Task27, release, or live action is recorded.

## Risks and mitigations

- The seal provides deterministic tamper detection and read-only permissions, not WORM protection against a privileged owner; this is explicitly outside the declared trust boundary.
- The 809 Ty diagnostics remain historical out-of-scope debt, but none intersects the sealed transport/capability spans.
- **Recommendation (Quick):** record this lane as `PASS` and keep the candidate roots untouched while the remaining independent Task26 lanes finish.
