## Summary
Stage 33 closes the Stage-32 transaction, recovery, and diagnostic-transport findings without weakening the prior fail-closed boundaries. The immutable index records the assigned revision SHA `1953a998a46428e8bedb211be135f2d9a0f77b6c7cf33feea5b16e77de112607`; implementation may proceed under the stated acceptance tests.

## Claims
- The immutable RALPLAN index records `stage-33-revision.md` as revision stage 33 with the assigned SHA-256.
- Current canonical append paths are split: `EventStore._record_lock()` owns `wizard/.events.lock` (`checkin_cli/store.py:411-425`), while `AdaptiveEventStore.append_canonical_event()` constructs `CanonicalSequenceJournal` with `adaptive_root/.events.lock` (`checkin_cli/adaptive_nutrition.py:4255-4274`). Current `CanonicalSequenceJournal.append()` also invokes `recover()` before entering a separate lock (`:5534-5538`).
- Current generic `AdaptiveEventStore.recover()` includes canonical event, canonical sequence, and overlay paths (`checkin_cli/adaptive_nutrition.py:4073-4110`), and several callers invoke it while holding the adaptive lock (`:4037-4039,4146-4148,4308-4310`).
- Current production delivery reads mutable `self.customer_transport` after reservation and admits generic callable/awaitable adapters (`gateway/platforms/nutrition_coaching.py:4741-4758,4850-4860,11069-11091`); `TelegramCustomerTransport` already reaches the native strict Telegram send boundary (`:11525-11653`; `telegram.py:3329-3335`).

## Analysis
### Stage-32 transaction closure
`CanonicalEventTransaction` supplies one derived wizard `.events.lock`, paired event/sidecar operations, unforgeable locked-operation tokens, and batch prevalidation. Its delegation rules cover `EventStore`, adaptive canonical operations, reconciliation, freeze, legacy-prefix validation, and the compatibility facade; the authoritative sidecar is fixed at `customer_root/nutrition-plans/canonical-sequence.jsonl`. This removes the current adaptive-root writer lock and the nested `recover()`/append locking pattern. The required concurrent EventStore/adaptive append, recovery, lock-mismatch, and no-nested-flock tests make the shared-writer claim falsifiable.

### Stage-32 recovery closure
The revision makes public recovery owner-specific and permits only the adaptive main/source/authority/config journals under `.adaptive.lock`; event/sequence and overlay recovery are delegated to their respective journal owners. Its tokenized already-locked paths directly address the existing nested calls while prohibiting arbitrary or cross-domain truncation. Required recovery-vs-reader, cross-domain rejection, and deadlock-free concurrency tests cover the relevant failure modes.

### Stage-32 transport closure
The host now freezes one exact production `TelegramCustomerTransport` instance, captures it in the session/spec digest, rechecks identity under the admission lock, and passes that instance explicitly through provider completion. The sealed deadline-aware diagnostic method uses native Telegram connect/pool/write/read bounds plus the existing outer async timeout; mutable coordinator transport lookup and compatibility adapter admission are excluded from the diagnostic path. Setter-race, duck-type, synchronous, wrong-adapter, cancellation-resistant, identity-through-call, cancellation, and deadline tests close the prior transport-instance and post-cancellation-send gaps.

### Antithesis and synthesis
Keeping `CanonicalSequenceJournal` as an independently configurable public writer or allowing a generic transport maximizes compatibility, but it preserves the exact split-lock and mutable-instance attacks found in Stage 32. The chosen strict transaction and frozen-instance boundaries intentionally narrow diagnostic-only extensibility; ordinary production behavior remains outside those constraints.

## Root Cause
Stage 32 still allowed canonical ownership to be selected at individual callsites, recovery to mutate foreign domains, and the transport object to be replaced or compatibility-dispatched after diagnostic admission. Stage 33 moves each authority decision to one typed owner and makes the remaining contracts testable.

## Findings
None. No CRITICAL, HIGH, MEDIUM, or LOW issue remains in the Stage-32 transaction, recovery, or transport closure.

## Recommendations
1. Implement the Stage-33 binding addendum exactly, retaining the Stage-28 through Stage-32 constraints by reference.
2. Treat the listed deterministic transaction/recovery/transport race tests as release-gating; do not replace them with source-only or mock-only coverage.
3. Preserve the existing human-only Telegram, deployment, and real-customer boundaries.

## Architectural Status
CLEAR

## Code Review Recommendation
APPROVE

## Tradeoffs
- **Single typed canonical transaction (chosen):** removes split locks and nested flock; requires coordinated EventStore/adaptive integration.
- **Independent configurable canonical journal:** lower migration effort, but permits divergent lock domains; reject.
- **Frozen exact diagnostic transport (chosen):** bounds identity, cancellation, and native request time; intentionally disallows diagnostic compatibility adapters.
- **Generic mutable transport:** easier test injection, but leaves setter and compatibility races; reject.
