# 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.
> Execute the plan's selected root cause, scope, files, and dependency decisions as written. Do not choose another owner, narrow/expand the write boundary, or replace a fix with another verification attempt.
> 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=2026-08-07
task=m-iop-owned-single-request-agent-execution/20+19_review_stage, plan=0, tag=API

## 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-G09.md` → `code_review_cloud_G09_0.log` and `PLAN-cloud-G09.md` → `plan_cloud_G09_0.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/m-iop-owned-single-request-agent-execution/20+19_review_stage/`. If WARN/FAIL, fully write the next filesystem state required by the code-review skill.
4. If PASS, preserve `milestone-task=review-stage` in `complete.log` and report it for runtime aggregation. Roadmap state evaluation belongs to `sync-milestone-workstate`.
5. Check applicable `Review-Only Checklist` items at the final `.log` location before reporting.

## Implementation Item Completion

| Item | Status |
|------|---------|
| API-1 Implement strict Review and persisted pass evidence | [ ] |
| API-2 Drive bounded repair and mandatory re-review | [ ] |
| API-3 Compose the three private stages | [ ] |
| API-4 Install and synchronize the active contract | [ ] |

## Implementation Checklist

- [ ] Implement the Gemini high-reasoning Review runner that reads PLAN and Work evidence, accepts only strict pass output, persists REVIEW before finalization, and fails closed on malformed or provider-error outcomes.
- [ ] Implement the one-tool-at-a-time repair path with `repairing -> internal_tool(saved repairing) -> repairing`, exact continuation correlation, bounded re-review, and no release of an unreviewed Work candidate.
- [ ] Add the concurrent request-safe composite executor that drives Plan → Work → Review through one controller, exposes the predecessor's continuation bridge, and returns only reviewer-approved final output.
- [ ] Install the composite executor at Edge input startup and add deterministic S10, full lifecycle, concurrent isolation, cancellation, cleanup, and installation fixtures without altering the public Anthropic schema.
- [ ] Update the current outer contract and implementation spec, then run dependency, focused race, installation, regression, vet, deterministic contract/spec, and diff checks while leaving S12 external evidence deferred.
- [ ] 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_G09_0.log`.
- [ ] Archive active `PLAN-*-G??.md` to `plan_cloud_G09_0.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-iop-owned-single-request-agent-execution/20+19_review_stage/` to `agent-task/archive/YYYY/MM/m-iop-owned-single-request-agent-execution/20+19_review_stage/` and update this checklist at the final archive path.
- [ ] If PASS, preserve and report `milestone-task=review-stage` for runtime aggregation, without modifying roadmap or directly calling `update-roadmap`.
- [ ] If PASS for split work, remove empty active parent `agent-task/m-iop-owned-single-request-agent-execution/` 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

- Verify every Review dispatch uses frozen Gemini admission with effective high reasoning and only the immutable task, PLAN, bounded Work candidate, and verification evidence.
- Verify defect handling permits exactly one admitted IOP repair call at a time and observes `reviewing -> repairing -> internal_tool(saved repairing) -> repairing -> reviewing` before any pass.
- Verify REVIEW persistence precedes finalizing, only reviewer-approved bytes reach the caller, and malformed/provider/tool/artifact/cancel paths expose no candidate or provider detail.
- Verify the composite stores no unkeyed per-request mutable state, correlates concurrent continuations exactly, and cleans waiters plus service resources on every exit.
- Verify production startup installs the composite through the existing setter without changing the public Anthropic schema, and contract/spec text leaves S12 external qualification deferred.

## Verification Results

Paste actual stdout/stderr for every command. If a command changes, record the replacement and reason in `Deviations from Plan` before pasting its output.

### 1. Dependency evidence

`test -f agent-task/m-iop-owned-single-request-agent-execution/19+18_work_stage/complete.log`

Expected: exit zero before implementation or review.

```text
_Paste actual output here._
```

### 2. Focused Review/composite race tests

`go test -race ./apps/edge/internal/openai -run 'TestSingleRequest(ReviewStage|Executor)' -count=1`

Expected: S10, repair, composite, concurrency, cancellation, and failure fixtures pass without races.

```text
_Paste actual output here._
```

### 3. Production installation

`go test ./apps/edge/internal/input -run 'TestManager.*SingleRequestExecutor' -count=1`

Expected: production construction installs the executor and does not regress to unavailable.

```text
_Paste actual output here._
```

### 4. Changed-package regression

`go test ./apps/edge/internal/service ./apps/edge/internal/openai ./apps/edge/internal/input -count=1`

Expected: coordinator, public handler/stream, OpenAI, and input regressions pass freshly.

```text
_Paste actual output here._
```

### 5. Vet and Edge regression

`go vet ./apps/edge/internal/service ./apps/edge/internal/openai ./apps/edge/internal/input && go test ./apps/edge/... -count=1`

Expected: changed packages vet cleanly and broader Edge regression passes.

```text
_Paste actual output here._
```

### 6. Lifecycle and installation evidence

`rg --sort path -n 'NewSingleRequestExecutor|SetSingleRequestExecutor|reasoning_effort|SingleRequestArtifactReview|finalizing|repairing' apps/edge/internal/openai apps/edge/internal/input --glob '*.go'`

Expected: installation, high Review option, repair, REVIEW persistence, and finalization ordering are explicit and test-covered.

```text
_Paste actual output here._
```

### 7. Contract and spec synchronization

`rg --sort path -n 'Plan|Work|Review|repair|active|claude-smoke|S12|deferred' agent-contract/outer/anthropic-compatible-api.md agent-spec/runtime/edge-node-execution.md`

Expected: documents describe active local behavior and leave external qualification deferred.

```text
_Paste actual output here._
```

### 8. Diff hygiene

`git diff --check`

Expected: exit zero with no output.

```text
_Paste actual output here._
```

External note: actual provider/Claude full-cycle evidence remains owned by SDD S12 `claude-smoke`.
