I read this as a final read-only GOAL/CONSTRAINT audit of Task26 candidate `5948498c...` - I’ll inspect the plan, ledger entry, current source, immutable v12 evidence bundle, and postfreeze receipts, then return a strict PASS/FAIL/INCONCLUSIVE with blockers and residual risk.


I read this as a final read-only GOAL/CONSTRAINT audit - report the strict verdict, evidence, blockers, and residual risk for candidate `5948498c...`.

## Bottom line

**PASS** for this Task26 audit lane. Candidate `5948498c6297d31f9cc8adfb26b0e3e1f3c8e5ade706e36dfae2c97997499a63` closes every named prior blocker with consistent source, installed, frozen, rehydrated, provenance, authority, lifecycle, and cleanup evidence.

This is **not** Task26 completion or release authorization: the plan remains NO-GO, Task26/Task27 remain unchecked, and ledger line 160 explicitly records `task26_complete=false`, `task27_started=false`, and `release_authorized=false`.

## Evidence

- **Pre-execution identity:** canonical SHA-256 of `preexecution-product-binding.json.derivation_inputs` independently recomputes to exactly `5948498c...`. Inputs are the two wheels, 107-wheel recursive inventory, trust-boundary digest, and qualification-tool bytes; Golden/evidence outputs are excluded.
- **Temporal binding:** both Golden drivers consumed the exact pre-execution binding file SHA `066a6ded...`; driver code validates that binding before creating or executing the Golden profile.
- **Cross-mode identity:** source, installed, outer manifest, source/installed authority, frozen source, frozen independent, and rehydrated outputs all report exactly `5948498c...`.
- **Separate provenance:** `b34b2a12fd0ad3d4c95a58c847a2411e81272a646f5a4f5ec568d0d3640a3747` remains distinct from candidate identity and matches source/installed/frozen/rehydrated modes. Its 137-file inventory recomputes exactly and currently has zero missing or changed files.
- **Current source parity:** all 966 wheel members having current repository counterparts are byte-identical; the eight pre-execution qualification tools also match their bound hashes.
- **Native seven-clause chains:** both chains independently recompute without errors:
  - source: 7 clauses, head `a369935445fe01bb30374464ee733526a66eee28d74aae4d5954bd5a0cea07ba`
  - installed: 7 clauses, head `0f23389abbc94d341cf9a33f8bbb1b68d6a403065df7841f4fcfc06824827c98`
- **Composed Korean:** all 22 natural-language answers were consumed once with zero re-asks; `"보통 수준입니다."` canonicalizes to `moderate`. Manual source/installed receipts accepted 11 unambiguous composed variants while leaving 3 ambiguous forms unresolved.
- **Forgery resistance:** summary-only, self-authored lifecycle, candidate/source-tree substitution, cross-mode mismatch, and coherently re-signed semantic forgery paths are rejected. Recorded attack suites passed `6+6` candidate attacks and `9+9` wheelhouse/trust/origin attacks.
- **Frozen verification:** all 367 bundle files are immutable (`0400`, directories `0500`), single-link, owner-bound, with no symlinks. Candidate inventory, candidate document, bundle seal, authority documents, expected state, and postfreeze seal all recompute exactly.
- **Isolation/origins:** Python `-I`, no inherited `PYTHONPATH`, private empty CWD, explicit wheels only, and `--no-index --no-deps --no-compile`. Gateway/profile origins are RECORD-bound, and malicious caller shadowing is absent.
- **Recursive wheelhouse:** 107 wheels form the validated dependency closure; before/after inventories are byte-identical at `9bdc1462...`.
- **Trust boundary:** accurately limits guarantees to the trusted operator, kernel, selected Python/pip toolchain, and sealed wheel bytes; it claims no external authenticity, non-repudiation, WORM, or compromised-admin resistance.
- **Authority/revocation:** append-only registry/ledger contain 21 events. v10, failed-closed v11, and all older listed candidates are revoked; only `5948498c...` is current.
- **Zero-inotify:** `dnotify_signalfd_v1`, one directory resource, zero process/observer inotify watches, five chained observer receipts.
- **Exactly once and cleanup:** one provider call, one `sent_audited` delivery, one customer-surface receipt, consumed one-use capability, duplicate rejection, and unknown-outcome no-retry. Cleanup resumes through `prepared -> copied_verified -> source_pruned -> committed`; active/pending/unknown/orphan counts are all zero.
- **Postfreeze cleanup:** original, independent, temporary, malicious-caller, and controlled-CWD runtimes are absent; rehydration stderr is empty and portable results match.
- **Verification receipts:** 8,327 Gateway tests, 749 profile tests, 83+83 cross-mode, 196+196 parser/policy, 129+129 lifecycle, and 16+16 observer tests passed; static checks and pip check passed.

## Action plan

1. Record this objective/constraint lane as **PASS** with no candidate remediation required.
2. Preserve v12 and its postfreeze bundle unchanged.
3. Advance only through the remaining Task26 review lanes; do not begin Task27 or authorize release. **Effort: Quick** bookkeeping only.

## Risks and mitigations

- **Blockers:** none for this lane.
- **Residual risk:** evidence authenticity remains inside the declared local trust boundary; compromised operator/admin or host integrity is out of scope.
- **Release risk:** Task26 is still pending all independent lane verdicts. The current PASS must not be interpreted as a release or pilot authorization.
- No product, evidence, profile, service, network, Telegram, Task27, or release action was performed.
