## Verdict
**REJECT**

## Claim Checks
- **Immutable input verified.** `index.jsonl` binds `stage-40-revision.md` to SHA-256 `d88cada5457c027da90bfbad59a82060c9953f2dff06c75c42532a595bda798e`, matching the assignment. No Architect artifact was read.
- **Baseline facts substantially match.** The sealed registry is `ordinary_v1`; the canonical event and sequence ledgers contain 44 nonblank rows, source-day mappings/intents contain 44/88 nonblank rows, and `feature-epoch.json` has epoch 3 with activation true, delivery false, and config digest `09314d41…f14f92`. Full pair/digest validation was not executed because this review is read-only and tests were forbidden.
- **The source contract defect is real.** `history_imports.py:_baseline_event()` emits no manifest; `models.py:Event` currently has neither manifest nor adherence/retraction fields; `project_canonical_events()` excludes archived rows before checking `import_manifest` and reads the manifest from the terminal row. The typed `CanonicalAdherenceSignal` already exists and should be reused.
- **The lock/recovery observations are real.** `store.py:_append_many_locked()` currently accepts a dedupe collision without payload equality; `_append_pair_locked()` fsyncs the event file and sequence file in separate steps; `customer_admin.py` reconciliation calls `canonical_transaction.recover()` and derives each mapping day from that record's `occurred_at_kst`.
- **Representative import simulation fails on the actual target.** The fixed window overlaps existing canonical terminals on 2026-07-14 through 2026-07-20, 2026-07-22 through 2026-07-24, and 2026-07-27. Those rows/chains are accepted nutrition/correction evidence with manual provenance, not childless archived `history_imported` roots. Section 4.3 therefore classifies the first overlap as `foreign_collision` and writes zero events. The plan's advertised `[0,30]` success delta and all downstream acceptance criteria are unreachable on the sealed target.
- **Representative crash simulation is not recoverable.** A crash after the event append/fsync but before the sequence append/fsync leaves unequal ledgers. The proposed retry starts with `_read_snapshot_locked()`, which rejects the pair, while the plan forbids recovery/truncation and explicitly calls a torn pair unrecoverable. Faults only after completed pair boundaries do not establish crash-safe import.
- **Representative reconcile/retract simulation breaks the existing gateway invariant.** Import adds 29 roots plus one correction, but §4.5 writes one mapping per root. `gateway/platforms/nutrition_coaching.py:_validate_journal_consistency()` requires the set of source-day `root_event_id` values to equal the full canonical-sequence event-ID set. The proposed totals diverge by the correction immediately and diverge again after a retraction event. The plan does not modify that validator. After reconciliation followed by retraction, the already-appended synthetic source-day and intent rows also remain active-looking; “no new mappings” does not remove or semantically retract them.
- **The claimed read-only boundary loader is not read-only.** `_registered_customer()` calls `load_runtime_customer_registry()`, which calls `_recover_activation_journal()`. Import/retract therefore cannot use that path while also proving registry/activation bytes are unchanged on every failure branch. The canonical lock also does not protect concurrent feature/revision changes in the separate adaptive lock domain.
- **Root-digest construction itself is precise.** The newline-terminated canonical JSON preimage, lowercase SHA-256, sorted unique 29-root membership, and exclusion of corrections/baseline/foreign roots are actionable. The surrounding derived-journal semantics are not.

## Missing Evidence
- A collision matrix against the current 44-row target and a reachable success path for every overlapping day.
- Intra-pair fault injection at event write/flush/fsync and sequence write/flush/fsync, plus an append-only completion protocol that restores a valid pair without truncation.
- A single documented invariant spanning canonical sequence, source-day mappings/intents, corrections, partial generations, and retractions, including the production gateway reader after retraction.
- A genuinely non-recovering runtime/binding loader and a lock order covering canonical plus protected adaptive preconditions.
- Exact scenario formulas/golden outputs for every field and enum, and the named expected proposal decision token. The table leaves training/digestion/pain selection and several target/actual/weight adjustments under-specified. It also says `adherent=false, status=adequate`, contrary to `derive_canonical_adherence_signal()`, which emits `status="inadequate"` when deviations exceed tolerance.
- Successful-run pre/post digest assertions for every artifact declared immutable (`adaptive-overlays`, registration, policy, lifecycle/reservation/delivery), not only feature bytes and proposal revision.

## Approval Boundary
No implementation or target mutation is approved from revision 40. The typed manifest/adherence/root-digest direction may be retained, but the integrated import, reconciliation, retraction, and execution phases require planner revision. Pair-transaction and gateway/retraction semantics need architect analysis before execution.

## Summary
- **Clarity:** High locally, but contradictory at the target boundary.
- **Verifiability:** Good digest/test vocabulary; missing decisive intra-pair, current-overlap, and post-retraction gateway cases.
- **Completeness:** Incomplete because the sealed target deterministically rejects and derived reconciliation cannot remain gateway-consistent.
- **Big Picture:** Canonical append-only and no-live goals are appropriate; the current two-file and derived-journal design does not realize them end to end.
- **Principle/Option Consistency:** Violates the chosen crash-safe, read-only-reconciliation, and gateway-parity principles.
- **Alternatives Depth:** Broad, but no viable option for the actual incompatible overlaps or pair-atomic append.
- **Risk/Verification Rigor:** Strong at completed pair boundaries; insufficient at physical append boundaries, cross-domain locks, and retraction aftermath.

## Required Changes
1. Rebase the scenario against the actual terminal chains. Either choose an approved non-overlapping 30-day window or specify a safe coexistence rule for each present day; pin exact append/skip counts. Do not label the present nutrition/correction chains compatible under the current predicate.
2. Design a truly crash-safe append-only pair protocol. Cover every write/flush/fsync boundary and allow deterministic additive completion of an event/sequence fragment or pair; a permanently torn ledger is not acceptable.
3. Reconcile one explicit coverage model with `AdaptiveOperatorService._validate_journal_consistency()`: either map every canonical event (including corrections/retractions) or update the production gateway to resolve eligible roots. Add correction and retraction E2E tests against the real set-equality invariant.
4. Define append-only derived compensation for retraction (typed tombstone/status rows plus reader filtering, or an equivalent immutable projection) so previously reconciled synthetic mappings no longer count as active evidence while prefixes remain byte-exact.
5. Replace `_registered_customer()` usage in sealed import/retract with a strict no-recovery loader, specify canonical/adaptive lock ordering and inode/digest rechecks, and test concurrent feature/revision changes.
6. Complete the scenario recipe and acceptance oracle: exact per-field generation, `inadequate` status for non-adherent signals, schema coverage of all `CanonicalAdherenceSignal` fields, golden vectors, scoped projection counts, and the literal expected decision enum.
7. Assert byte/digest immutability for every protected artifact on successful, failed, replay, and retraction paths.
