# Code Review Reference - REVIEW_REFACTOR

> **[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=2026-07-28
task=agent_task_english_contract, plan=2, tag=REVIEW_REFACTOR

## Archive Evidence Snapshot

- Prior plan: `agent-task/agent_task_english_contract/plan_cloud_G07_1.log`
- Prior review: `agent-task/agent_task_english_contract/code_review_cloud_G07_1.log`
- Verdict: `FAIL`
- Required findings: pair each canonical or legacy verdict heading with only its matching label; replace the convergence test's completion-scan timing sleep with an observation barrier; cover the complete canonical-label, explicit legacy-alias, verdict-finalization, and prompt-language contract.
- Suggested findings: none.
- Nit findings: none.
- Affected files: `agent-ops/skills/project/orchestrate-agent-task-loop/scripts/dispatch.py` and `agent-ops/skills/project/orchestrate-agent-task-loop/tests/test_dispatch.py`.
- Verification evidence: reviewer `py_compile`, five language-contract tests, seven focused tests, the fresh 267-test suite, and `git diff --check` passed. A direct parser probe still returned `PASS` for canonical heading plus Korean label and `WARN` for Korean heading plus canonical label, proving the uncovered contract defect.
- Roadmap carryover: none. This task is not Milestone-linked and has no `Roadmap Targets`.
- Implementation rule: use this snapshot and the two named logs as prior-loop evidence; do not search `agent-task/archive/**`.

## 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-G07.md` → `code_review_cloud_G07_2.log` and `PLAN-cloud-G07.md` → `plan_cloud_G07_2.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/agent_task_english_contract/`. 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 |
|---|---|
| [REVIEW_REFACTOR-1] Paired verdict schemas and complete language-contract coverage | [x] |
| [REVIEW_REFACTOR-2] Completion-triggered scan observation barrier | [x] |

## Implementation Checklist

- [x] [REVIEW_REFACTOR-1] Enforce paired canonical/legacy verdict schemas and complete the deterministic artifact-language contract matrix.
- [x] [REVIEW_REFACTOR-2] Replace the completion-scan timing sleep with an explicit scan-observation barrier.
- [x] 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.

- [x] Append one verdict of `PASS`, `WARN`, or `FAIL` and verified `review_rework_count`, `evidence_integrity_failure` to `Code Review Result`.
- [x] Verify that verdict, `Dimension Assessment`, and Required/Suggested/Nit classifications match.
- [x] Archive active `CODE_REVIEW-*-G??.md` to `code_review_cloud_G07_2.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_cloud_G07_2.log`.
- [x] Verify that the Agent-Ops managed block in `.gitignore` unignores `agent-task/**/*.md` and `agent-task/**/*.log` and ignores `agent-roadmap/current.md`.
- [x] If PASS, write `complete.log` based on `agent-ops/skills/common/code-review/templates/complete-log-template.md` and leave no active `.md` files.
- [x] If PASS, move active task directory `agent-task/agent_task_english_contract/` to `agent-task/archive/YYYY/MM/agent_task_english_contract/` 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/agent_task_english_contract/` 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

None. Every planned command was run exactly as written. The only presentation note is in `Final Verification`: the fresh discovery run writes 1238 stdout lines, almost all of them per-test Korean runtime banners, so the pasted block keeps the run's first and last lines verbatim and states the omitted middle explicitly instead of reproducing unrelated banner noise. All other blocks are complete verbatim output.

## Key Design Decisions

- Replaced the independent heading/label alternations with a single source of truth, `CODE_REVIEW_RESULT_SCHEMAS = (("Code Review Result", "Overall Verdict"), ("코드리뷰 결과", "종합 판정"))`, and derived `VERDICT_SCHEMA_MATCHERS` from it with `re.escape`, so heading, inline label, and `###` block label regexes for one schema can never be combined with another schema's label. The previously declared but unused `CODE_REVIEW_RESULT_HEADINGS` / `OVERALL_VERDICT_LABELS` constants and the three cross-product `VERDICT_*_RE` patterns were removed rather than kept in parallel; a repository-wide search confirmed `dispatch.py` was their only consumer.
- `verdict_from_text` now selects at most one schema section: it fails closed when one schema's heading appears more than once and when headings from both schemas appear in the same file, then matches only the selected schema's paired label. Existing accepted behavior is preserved — the section slice still ends at the next `## ` heading, verdict strings outside the section are still ignored, and multiple verdict matches inside the section still return `None`.
- `ArtifactLanguageContractTest.test_verdict_schema_pairs_reject_mixed_heading_labels` drives the matrix from `dispatch.CODE_REVIEW_RESULT_SCHEMAS` itself (2 headings x 2 labels x inline/block), so the two valid pairs return `PASS` and both mixed directions return `None` in both verdict forms. Pinning the constant's exact value in the same test keeps the pairing itself, not just the parser, under regression.
- The language-contract test now reads all four contract documents (plan skill, code-review skill, review stub template, orchestrator skill) with no modification to them. It asserts the nine canonical labels in the plan skill, the exact explicit legacy-alias pairing strings in each document, canonical `## Code Review Result` finalization plus the `Overall Verdict` field rule in the code-review skill, and the orchestrator's documented verdict pair rendered from `dispatch.CODE_REVIEW_RESULT_SCHEMAS`, which ties the runtime constant to the documented contract.
- A per-line rule asserts that each legacy Korean artifact label in those documents appears only on a line that also says `legacy`. Korean roadmap, `USER_REVIEW.md`, runtime banner, and user-facing response literals are deliberately outside this rule; the Korean runtime message `구현 체크리스트 미완료` stays asserted as runtime output in `test_canonical_english_sections_drive_runtime_contract`.
- Prompt coverage was widened from one worker prompt to thirteen: worker, Pi worker, self-check, official review, review-without-stub, review recovery, logical context, native continuation, Pi worker continuation, Pi self-check continuation, ordinary worker continuation, and both package continuation forms. Each is asserted to carry `Keep artifact content in English.` and `Final in Korean.`. No public parser or prompt function name changed.
- The convergence simulation's ordering sleep was replaced by a `completion_scan_observed` event set from a synchronous wrapper around the captured real `dispatch.scan_tasks`. The wrapper fires only when beta has finished and the dispatcher's own `exclude_names` still contains the running `sim/01_alpha`, so alpha is released by the observed completion-triggered scan rather than by elapsed time. The wrapper is still installed through `mock.patch.object(..., wraps=...)`, so the existing scan-count, `exclude_names`, review-attempt, archive, and work-log assertions are unchanged, and one added assertion proves the barrier actually fired. Unrelated short sleeps that only create worker/self-check overlap were left in place, and no production scheduler code was touched.
- Determinism was checked beyond the single planned run: the convergence test was executed 15 consecutive times with no failure.

## Reviewer Checkpoints

- Canonical and legacy verdict headings accept only their paired labels in inline and block forms; both mixed directions and duplicate headings fail closed.
- The language-contract suite reads the plan skill, code-review skill, review template, and orchestrator skill and checks every required canonical label plus explicit legacy alias.
- Worker, Pi worker, self-check, official-review, review-recovery, logical-context, native continuation, and ordinary continuation prompts preserve the artifact/final language boundary.
- The convergence simulation releases alpha from an observed completion-triggered scan with alpha in `exclude_names`, not from elapsed time.
- No central common rule or skill, production scheduler path, provider seam, roadmap artifact, or unrelated user change is modified.

| Archive Evidence Snapshot | Fixed at stub creation from plan | 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 |

## Code Review Result

- **Overall Verdict**: PASS
- **Dimension Assessment**:
  - Correctness: Pass — canonical and legacy verdict headings now accept only their paired labels, mixed schemas fail closed, and the completion-scan fixture releases the running task from an observed dispatcher scan.
  - Completeness: Pass — both implementation items and all implementation-owned evidence fields are complete.
  - Test Coverage: Pass — the valid/mixed inline and block verdict matrix, canonical/legacy contract documents, 13 prompt paths, and the completion-scan observation barrier are covered.
  - API Contract: Pass — runtime verdict parsing matches the canonical and explicit legacy schema pairs documented by the orchestrator contract.
  - Code Quality: Pass — the verdict schema has one paired source of truth, obsolete cross-product regexes are removed, and the ordering-path timing sleep is eliminated.
  - Implementation Deviation: Pass — the implementation stays within the two planned files and records no unexplained deviation.
  - Verification Trust: Pass — fresh reviewer runs passed `py_compile`, the 7 focused tests, all 268 discovered tests, and `git diff --check`, matching the recorded evidence.
- **Findings**: None
- **Routing Signals**:
  - `review_rework_count=2`
  - `evidence_integrity_failure=false`
- **Next Step**: PASS finalization — archive the active pair, write `complete.log`, and move the task directory under `agent-task/archive/2026/07/`.
