# Code Review Reference - API

> **[IMPLEMENTING AGENT — READ FIRST] Filling in this file is the mandatory final step of implementation.**
> The task is NOT complete until every implementation-owned section below is filled in.
> Complete the `Implementation Checklist`; the final checklist item is mandatory before saving.
> Fill implementation-owned sections, then stop with active files in place and report ready for review.
> If implementation is blocked, record the exact blocker, attempted commands/output, and resume condition only in implementation-owned evidence fields.
> Do not ask the user directly, present choices, call user-input tools, create control-plane stop files, or classify the next state.
> Finalization (`Code Review Result`, log rename, `complete.log`, archive moves, `Review-Only Checklist`) is review-agent-only, even after compaction/resume.
> Follow the ownership table at the bottom of this file for which sections you own.

## Overview

date=2026-07-31
task=m-multi-provider-protocol-profile-native-messages/03+02_contract_responses_sync, plan=1, tag=API

## Roadmap Targets

- Milestone: `agent-roadmap/phase/operational-observability-provider-management/milestones/multi-provider-protocol-profile-native-messages.md`
- Milestone link: [Milestone 문서](agent-roadmap/phase/operational-observability-provider-management/milestones/multi-provider-protocol-profile-native-messages.md)
- Task ids:
  - `contract-sync`: profile config, tunnel operation, Chat/Messages public/inner 계약과 구현 spec 동기화
  - `responses-regression`: 선택적 Responses driver와 Pi 소비 동작 보존
- Completion mode: check-on-pass


## For the Review Agent

> **[REVIEW AGENT ONLY]** The finalization steps below are review-agent only. Implementing agents must not execute this section.

Compare implementation of each item against source files and verify that output in `Verification Results` matches code.
Review completion means the following steps are finished:

1. Append verdict and `review_rework_count` / `evidence_integrity_failure` routing signals.
2. Archive `CODE_REVIEW-cloud-G05.md` → `code_review_cloud_G05_01.log` and `PLAN-local-G05.md` → `plan_local_G05_01.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/m-multi-provider-protocol-profile-native-messages/03+02_contract_responses_sync/`. If WARN/FAIL, fully write the next filesystem state required by the code-review skill.
4. If PASS and task group is `m-<milestone-slug>`, report completion event metadata. Roadmap state check and `update-roadmap` calls are runtime responsibilities.
5. Check applicable `Review-Only Checklist` items at the final `.log` location before reporting.

## Implementation Item Completion

| Item | Status |
|------|---------|
| API-1 | [ ] |
| TEST-2 | [ ] |
| DOC-3 | [ ] |
| API-4 | [ ] |

## Implementation Checklist

- [ ] Migrate provider-pool Responses passthrough to the optional profile operation/capability boundary while preserving legacy no-profile, normalized, stream, provider-auth, and body/status semantics with S08 tests.
- [ ] Add an executable temp-home Pi installer regression and clarify the maintained `openai-responses` consumption path without changing user secrets or existing defaults.
- [ ] Using the routed contract/spec workflows, add the Anthropic outer contract and synchronize config/wire/OpenAI contracts plus current specs/indexes to implementation source paths, proving no duplicate source of truth for S04.
- [ ] Run focused Responses/Pi/drift checks and full packages/Edge/Node verification with fresh results.
- [ ] Fill implementation-owned sections in CODE_REVIEW-*-G??.md with actual implementation notes and verification output.

## Review-Only Checklist

> **[REVIEW AGENT ONLY]** This checklist is used only by the review agent.
> Implementing agents must not modify or check this section.

- [ ] Append one verdict of `PASS`, `WARN`, or `FAIL` and verified `review_rework_count`, `evidence_integrity_failure` to `Code Review Result`.
- [ ] Verify that verdict, `Dimension Assessment`, and Required/Suggested/Nit classifications match.
- [ ] Archive active `CODE_REVIEW-*-G??.md` to `code_review_cloud_G05_01.log`.
- [ ] Archive active `PLAN-*-G??.md` to `plan_local_G05_01.log`.
- [ ] Verify that the Agent-Ops managed block in `.gitignore` unignores `agent-task/**/*.md` and `agent-task/**/*.log` and ignores `agent-roadmap/current.md`.
- [ ] If PASS, write `complete.log` based on `agent-ops/skills/common/code-review/templates/complete-log-template.md` and leave no active `.md` files.
- [ ] If PASS, move active task directory `agent-task/m-multi-provider-protocol-profile-native-messages/03+02_contract_responses_sync/` to `agent-task/archive/YYYY/MM/m-multi-provider-protocol-profile-native-messages/03+02_contract_responses_sync/` and update this checklist at the final archive path.
- [ ] If PASS and task group is `m-<milestone-slug>`, report completion event metadata for runtime, without modifying roadmap or directly calling `update-roadmap`.
- [ ] If PASS for split work, remove empty active parent `agent-task/m-multi-provider-protocol-profile-native-messages/` or verify it was kept due to remaining siblings/files.
- [ ] If WARN/FAIL, write the next filesystem state matching code-review verdict and do not write `complete.log`.

## Deviations from Plan

_Record any deviations from the plan and the rationale here._

## Key Design Decisions

_Record key design decisions here._

## Reviewer Checkpoints

- Confirm predecessor `02+01_messages_ingress` PASS evidence existed before implementation.
- Confirm explicit profiles require the optional Responses operation/capability while legacy no-profile and normalized paths retain existing behavior.
- Confirm Responses body/status/stream/provider-auth output is byte/semantic compatible and unsupported profiles dispatch nothing.
- Confirm Pi tests execute the real installer only under temp HOME and preserve defaults, keys and `api: openai-responses` without network.
- Confirm `anthropic-compatible-api.md` is the single public Messages contract and other contracts/specs link instead of duplicating request schemas.
- Confirm every contract/spec index path resolves to actual source and the Claude gateway is migration evidence only.

## Section Ownership

| Section | Owner | Note |
|---------|-------|------|
| Header comment, Overview, Review Agent Instructions | Fixed at stub creation | Implementing agent must not modify or execute these (archive, complete.log, and task-directory archive move are review-agent only) |
| Roadmap Targets | Fixed at stub creation from plan when present | Implementing agent must not modify; code-review copies it into `complete.log` as `Roadmap Completion` only on PASS |
| Archive Evidence Snapshot | Fixed at stub creation from plan when present | Implementing agent uses it as default prior-loop context; read only the specific archive files cited there when more detail is required |
| Implementation Item Completion (item names) | Fixed at stub creation | Implementing agent checks `[ ]` → `[x]` only |
| Implementation Checklist (item text/order) | Fixed at stub creation from plan | Implementing agent checks `[ ]` → `[x]` only |
| Review-Only Checklist | Review agent only | Implementing agent must not modify or check this section |
| Deviations from Plan, Key Design Decisions | Implementing agent | Replace placeholder text with actual content |
| Reviewer Checkpoints | Fixed at stub creation | Pre-filled from plan |
| Verification Results (section headings + commands) | Fixed at stub creation | Implementing agent fills in command output only; command changes require a `Deviations from Plan` entry |
| Code Review Result | Review agent appends | Not included in stub |
