## Overview

date=2026-08-03
task=m-iop-hot-path-one-shot-execution/11+09,10_cleanup, plan=4, tag=REVIEW_REVIEW_REVIEW_REVIEW_API

## Archive Evidence Snapshot

- Current review archive after finalization: `agent-task/m-iop-hot-path-one-shot-execution/11+09,10_cleanup/code_review_cloud_G08_3.log`.
- Earlier reviews: `agent-task/m-iop-hot-path-one-shot-execution/11+09,10_cleanup/code_review_cloud_G10_0.log`, `agent-task/m-iop-hot-path-one-shot-execution/11+09,10_cleanup/code_review_cloud_G10_1.log`, and `agent-task/m-iop-hot-path-one-shot-execution/11+09,10_cleanup/code_review_cloud_G09_2.log`.
- Current verdict: FAIL; findings: Required 1, Suggested 0, Nit 0.
- Required gap: `workspaceResultIsExact` treats the empty-body success branch of `normalizeResultEnvelope` as an exact caller operation report and authorizes cleanup.
- Reviewer reproduction: a successful Plan receipt plus an empty Review receipt issued HTTP 200 with a canonical `delete_file` frontier on both OpenAI and Anthropic; the temporary reproducer was removed.
- Trusted passing evidence: the focused primary-error races, cleanup/TTL races, common race suites, full Edge suite, vet, formatting, and diff checks all passed; they omit the empty receipt variant.
- Affected implementation area: `workspace_tool_codec.go` exactness classification plus focused classifier and public-handler tests.
- Roadmap carryover: milestone task `cleanup`, approved and unlocked SDD Acceptance Scenario/Evidence Map row S09, with the existing S06/S14 opaque-result trust boundary preserved.

## 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-G06.md` → `code_review_cloud_G06_4.log` and `PLAN-cloud-G05.md` → `plan_cloud_G05_4.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/m-iop-hot-path-one-shot-execution/11+09,10_cleanup/`. 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>`, preserve the first-line `milestone-task` metadata in `complete.log` and report it for the runtime aggregation event. 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 |
|------|---------|
| REVIEW_REVIEW_REVIEW_REVIEW_API-1 — Separate empty opaque receipts from exact failures | [x] |
| REVIEW_REVIEW_REVIEW_REVIEW_API-2 — Lock the public empty-receipt boundary on both protocols | [x] |

## Implementation Checklist

- [x] Reject empty success-status workspace results as opaque while preserving explicit status failures and non-empty parseable matcher failures as exact.
- [x] Add classifier and both-endpoint public-handler regressions for empty receipt rejection without regressing `{"written":false}` primary cleanup.
- [x] Run all focused and final verification commands with fresh output.
- [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_G06_4.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_cloud_G05_4.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/m-iop-hot-path-one-shot-execution/11+09,10_cleanup/` to `agent-task/archive/YYYY/MM/m-iop-hot-path-one-shot-execution/11+09,10_cleanup/` and update this checklist at the final archive path.
- [x] If PASS and task group is `m-<milestone-slug>`, preserve and report `milestone-task` metadata for runtime aggregation, without modifying roadmap or directly calling `update-roadmap`.
- [x] If PASS for split work, remove empty active parent `agent-task/m-iop-hot-path-one-shot-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

None.

## Key Design Decisions

Distinguished empty success-status results from explicit status errors in `workspaceResultIsExact`. Empty success bodies (nil or whitespace-only) return false so they are classified as opaque and fail closed without issuing caller-executed cleanup frontiers. Explicit status errors (status "error", "failed", "failure") return true to remain exact failures eligible for cleanup, while non-empty parseable bodies such as `{"written":false}` continue to decode normally.

## Reviewer Checkpoints

- Confirm an empty or whitespace-only success-status result returns HTTP 400 without a `delete_file` frontier on OpenAI and Anthropic.
- Confirm an explicit status error remains an exact failure even when its body is empty.
- Confirm non-empty parseable `{"written":false}` still enters primary-error cleanup and retains the original endpoint error after cleanup acknowledgement failure.
- Confirm malformed JSON, wrong call identity, mutated issue correlation, lineage, owner, and principal remain immediate fail-closed rejections.
- Confirm the change does not modify receipt matching, cleanup state transitions, endpoint envelopes, provider-call counts, cancellation, TTL, or duplicate-cleanup behavior.

## Code Review Result

- Overall Verdict: PASS
- Dimension Assessment:
  - Correctness: Pass — empty and whitespace-only success-status results remain opaque, while explicit status failures and non-empty parseable matcher failures retain the intended primary-error cleanup path.
  - Completeness: Pass — both implementation items, their public OpenAI/Anthropic boundaries, and all planned verification steps are complete.
  - Test Coverage: Pass — focused classifier cases cover empty success, empty explicit failure, matcher failure, malformed/trailing JSON, and valid success; handler regressions cover empty receipt rejection on both protocols with the retained positive cleanup control.
  - API Contract: Pass — opaque results fail closed with endpoint-standard HTTP 400 responses and no caller-executed delete frontier, preserving the workspace receipt trust boundary.
  - Code Quality: Pass — the change is narrowly scoped, formatted, vet-clean, free of stale debug/TODO references, and its exactness comment now matches the implementation.
  - Implementation Deviation: Pass — the implementation matches the follow-up plan; only review-time checklist drift and a non-behavioral explanatory comment were repaired.
  - Verification Trust: Pass — every claimed focused, race, full Edge, vet, formatting, and diff command was rerun successfully with fresh reviewer evidence.
  - Spec Conformance: Pass — the implementation satisfies SDD S09 cleanup behavior while preserving the S06/S14 opaque-result fail-closed boundary.
- Findings: None.
- Routing Signals:
  - `review_rework_count=4`
  - `evidence_integrity_failure=false`
- Next Step: Archive the active pair, write `complete.log`, move the split task to the monthly archive, and report the milestone completion event metadata.
