## Summary
REJECT. The plan is appropriately narrow in rejecting a new service/RAG system and specifies byte-identical canonical fallbacks, but it does not implement three non-negotiable boundaries: OpenAI-only/no-Kimi transport, typed code-originated grounding for every declared surface, and deterministic enforcement of semantic locks.

## Claims
- The existing humanizer accepts arbitrary Korean text in its editable slots after structural checks; its current checks do not encode allowed actions, relative timing, or safety assertions (`gateway/platforms/korean_humanizer.py:99-115`).
- `_humanize_korean_copy` currently receives only a rendered canonical string (`gateway/platforms/telegram.py:6100-6115`), while adaptive and weekly callers provide no finalized snapshot/context (`telegram.py:4554-4556`, `6500-6524`).
- The planned reuse of `_request_physique_coach_completion` is not OpenAI-only: it reads general provider/model config (`telegram.py:6162-6205`), and the shared resolver supports Kimi/Moonshot aliases (`agent/auxiliary_client.py:1040-1052`, `3449-3488`).
- The plan's no-live verification boundary is otherwise explicit and appropriate: it excludes provider deployment, Telegram activity, credentials, and synthetic data mutation.

## Analysis
The strongest case for the plan is that extending the existing slot document preserves canonical copies and keeps routing unchanged. That is the right integration direction. It does not, however, make a prose-only interface sufficient for a grounded two-stage contract. The current generic `(surface, canonical)` seam has discarded the code facts necessary to build a trustworthy `CoachingGrounding`, especially for scheduled weekly and adaptive operator cards. Parsing those facts back from canonical text would make prose authoritative and violate the stated boundary.

Likewise, returning principle IDs can prove only that identifiers were selected from an input allowlist; it cannot prove that a free-form replacement has not added a number-free instruction, a relative deadline, or a safety weakening. The plan must turn code decisions into typed immutable constraint atoms that the stage response selects/rephrases, rather than asserting an undefined semantic validator exists.

Finally, declaring no Kimi/Kimi3 while retaining the profile's unrestricted provider resolver is a contradiction. A current profile happens to use OpenAI Codex, but the requested boundary must be enforced in code and tested against Kimi/Moonshot/provider-proxy configurations, not assumed from deployment configuration.

## Root Cause
The plan treats a generic rendered-copy editor and a configurable general completion helper as though they already carry the authority needed for grounded, OpenAI-only coaching. They do not. Authority must be propagated as typed inputs and constrained at the transport and validation boundaries before either model call.

## Findings
1. **HIGH** — `gateway/platforms/telegram.py:6162-6205`: No OpenAI-only allowlist prevents Kimi/Moonshot through the shared resolver. Reported as P1: Enforce the OpenAI-only transport boundary.
2. **HIGH** — `gateway/platforms/telegram.py:4554-4556`: The plan does not pass typed grounding to daily, weekly, and adaptive call sites; a helper with only canonical text cannot safely recover it. Reported as P1: Pass typed grounding at every humanization call site.
3. **HIGH** — `gateway/platforms/korean_humanizer.py:99-115`: The proposed semantic locks lack a concrete deterministic representation/algorithm; current slot validation allows unsupported number-free actions, timing, and safety claims. Reported as P1: Define an enforceable semantic lock contract.
4. **MEDIUM** — `gateway/platforms/telegram.py:6100-6115`: The receipt has no named observable sink or revision binding and would be dropped by the current string-only seam. Reported as P2: Bind the sanitized receipt to an observable revision.

## Recommendations
1. Add a dedicated completion gate before `resolve_provider_client`: permit only explicitly configured OpenAI provider/model identities, reject Kimi/Moonshot family and proxy model slugs before client creation, and assert zero request calls in focused tests.
2. Change the integration seam to accept a typed, frozen `CoachingGrounding` obtained from code facts at each call site. Define separate builders for daily finalized snapshots, weekly finalized report inputs, and adaptive finalized proposal/revision inputs. Where no trusted builder exists, keep that surface canonical-only rather than parsing rendered text.
3. Define `LockedConstraints` with immutable allowed claim/action/timing/safety atoms, immutable slot identity/order, and approved evidence IDs. Require stage-one structured output to reference only those atoms; validate it before rendering. Stage two may only replace the already-validated prose slots and must be revalidated against the same original constraints.
4. Specify a non-sensitive receipt sink and revision/digest binding compatible with the existing immutable audit model, or remove receipt observability from the acceptance criteria. Test that receipt fields exclude prompts, prose, identities, raw records, addresses, and credentials.
5. Extend acceptance tests with Kimi provider/model rejection; zero-call unavailable-grounding for every surface; number-free imperative/relative-time/safety-negation adversaries; ordered two-stage success; stage-specific no-retry fallbacks; and receipt-to-output-digest linkage.

## Tradeoffs
- **Explicit typed per-surface context (recommended):** preserves code authority and enables a real allowlist; requires narrow call-site signature updates.
- **Infer context from canonical prose:** smaller apparent diff, but makes presentation text authoritative and cannot safely distinguish facts/actions; reject.
- **Canonical-only for unsupported surfaces:** maintains safety and narrowness but does not meet the requested two-stage success path for those surfaces; acceptable only if the scope is explicitly reduced.
