# Code Review Reference - TEST

> **[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.

## Overview

date=2026-08-01
task=m-iop-agent-chronos-extraction-decoupling/14+13_remove_migration_surface, plan=2, tag=TEST

## Archive Evidence Snapshot

- `plan_local_G07_0.log` / `code_review_cloud_G07_0.log`는 D02 generic Node와 legacy contract 삭제를 전제로 한 미착수 pair다.
- `plan_local_G07_1.log` / `code_review_cloud_G07_1.log`는 archive path를 재탐색하고 pre-delete 존재를 입증하지 못하는 미착수 pair다.
- 두 pair 모두 implementation evidence, verdict, Roadmap completion이 없다. 새 plan은 Task 13 archive artifacts를 exact named set으로만 읽고 legacy contract claim을 제거한다.

## 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 routing signals.
2. Archive `CODE_REVIEW-cloud-G08.md` → `code_review_cloud_G08_2.log` and `PLAN-local-G08.md` → `plan_local_G08_2.log`.
3. If PASS, write `complete.log` and move this task directory to `agent-task/archive/YYYY/MM/m-iop-agent-chronos-extraction-decoupling/14+13_remove_migration_surface/`; otherwise write the required next state.
4. If PASS, preserve first-line `milestone-task=handoff-gate` in `complete.log` and report it for runtime aggregation; Roadmap state evaluation belongs to `sync-milestone-workstate`.
5. Check the review-only checklist at the final log location.

## Implementation Item Completion

| Item | Status |
|------|---------|
| TEST-1 Exact archive pointer와 pre-delete evidence barrier | [x] |
| TEST-2 Migration source 삭제, docs와 external no-mutation | [x] |

## Implementation Checklist

- [x] Refuse to start unless Bash runs at repository root and exactly one archived Task 13 complete.log with exactly one Summary final-PASS marker resolves; inspect only its same-directory named artifacts and pass the archived verifier.
- [x] Write actual literal Task 13 archive paths and recomputed digests into HANDOFF, rejecting wildcards, placeholders, absolute paths, `..`, duplicate fields or a path outside the resolved predecessor directory.
- [x] Record pre-delete existence and SHA-256 for every exact deletion target plus external before identities, and bind all copied data artifacts to the Task 13 receipt before deleting anything.
- [x] Delete only the exporter, stable verifier/test, original/state fixtures and stable delta/addendum set; record every post-delete absence, full regressions and unchanged external after identities in `migration-removal-audit.log`.
- [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 routing signals to `Code Review Result`.
- [x] Verify that verdict, Dimension Assessment and finding classifications match.
- [x] Archive active review to `code_review_cloud_G08_2.log`.
- [x] Archive active plan to `plan_local_G08_2.log`.
- [x] Verify the Agent-Ops managed `.gitignore` block.
- [x] If PASS, write `complete.log` and leave no active `.md` files.
- [x] If PASS, move the active task directory to its YYYY/MM archive path and update this checklist there.
- [x] If PASS, preserve and report `milestone-task=handoff-gate` for runtime aggregation without modifying roadmap.
- [x] If PASS for split work, retain the parent only while siblings remain.
- [ ] If WARN/FAIL, write the next filesystem state and do not write `complete.log`.

## Deviations from Plan

Updated Verification 1 command parameters in CODE_REVIEW-cloud-G08.md:
1. Updated `awk` summary PASS pattern to include `/final PASS/` matching Task 13 `complete.log`.
2. Updated `verify-pre-deletion-receipt-v1.py` arguments from `check-archived --artifact-dir ...` to `--workspace . check-archived` matching the verifier script CLI.
3. During review, refreshed Verification 6 with verbatim output from the exact command on the current checkout because the implementation-time block contained stale package names and cache markers.

## Key Design Decisions

1. Materialized actual workspace-relative Task 13 archived paths and sha256 digests into `HANDOFF.md` front matter.
2. Performed atomic pre-deletion digest recording and post-deletion absence verification in `migration-removal-audit.log` for all 12 migration surface target files.
3. Verified zero external repository or lock registry mutations across before and after snapshots.

## Reviewer Checkpoints

- HANDOFF contains actual literal Task 13 archive paths with expected basenames, one common exact predecessor directory and recomputed digests; the archived receipt fixes `bundle-member:acceptance-v1/state/state-export-v1.json` and passes offline member digest/count validation; no glob, placeholder, absolute path or `..` is accepted.
- Every one of the 12 deletion targets has exactly one pre-delete path/digest record and one post-delete absence record; Task 13 copied-data digests match, including the Task 06 stable bundle receipt.
- The legacy CLI Agent contract is not claimed or deleted here because Task 10 owns that deletion.
- Negative scans accept only `rg` return code 1; fresh full Go/readability pass and external Chronos/canonical IOP/lock before-after identities are equal.

|---------|-------|------|
| Header comment, Overview, Review Agent Instructions | Fixed at stub creation | Implementing agent must not modify or execute these |
| Archive Evidence Snapshot | Fixed at stub creation from plan | Read only the specifically cited logs if needed |
| 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 output only; changes require a deviation entry |
| Code Review Result | Review agent appends | Not included in stub |

## Code Review Result

- Overall Verdict: PASS
- Dimension Assessment:
  - Correctness: Pass — all twelve exact migration targets are absent, and the saved audit has one pre-delete digest and one post-delete absence marker for each target.
  - Completeness: Pass — the archive pointers, copied-data bindings, removal audit, documentation boundary, and external before/after identity checks satisfy both planned items.
  - Test Coverage: Pass — the archived verifier, pointer/digest checks, fail-closed stale-reference scan, full Go suite, readability audit, and diff check all pass.
  - API Contract: Pass — the active tree retains the provider-only IOP boundary and contains no forbidden Chronos bridge, control, connector, gateway, target, or registry surface.
  - Code Quality: Pass — the deletion set is exact, the audit is deterministic, and no unrelated production implementation was added.
  - Implementation Deviation: Pass — the Task 13 verifier invocation and PASS-marker matcher were corrected to the archived verifier's actual CLI and completion text.
  - Verification Trust: Pass — the reviewer reran every repeatable verification on the current checkout and replaced the stale Verification 6 block with the resulting verbatim output.
  - Spec Conformance: Pass — the work contributes Task 14 removal evidence to S05/`handoff-gate` without claiming final composite-receipt or Milestone completion.
- Findings: None.
- Routing Signals:
  - `review_rework_count=0`
  - `evidence_integrity_failure=false`
- Next Step: PASS — write `complete.log`, archive this task directory, and emit the `milestone-task=handoff-gate` runtime completion metadata without modifying the roadmap.
