> 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.

## Overview

date=2026-08-06
task=m-iop-owned-single-request-agent-execution/09+08_workspace_wire, plan=3, tag=REVIEW_REVIEW_API

## Archive Evidence Snapshot

- Plan 2 and its failed review are preserved at `agent-task/m-iop-owned-single-request-agent-execution/09+08_workspace_wire/plan_cloud_G08_2.log` and `agent-task/m-iop-owned-single-request-agent-execution/09+08_workspace_wire/code_review_cloud_G09_2.log`. The verdict is `FAIL` with remaining Required R3; R1 cancellation and R2 admitted-reference behavior passed fresh verification.
- The reviewer reran the dependency, focused race, package, vet, and whitespace checks successfully. A focused four-family probe then proved that open, tool, cancel, and cleanup validators all accept the allowed status plus `WORKSPACE_ERROR_CODE_INTERNAL` and raw `Error`; the temporary probe file was removed.

## 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_3.log` and `PLAN-cloud-G05.md` → `plan_cloud_G05_3.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/09+08_workspace_wire/`. 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_API-1 Close workspace response outcome validation | [x] |

## Implementation Checklist

- [x] Accept open/tool/cleanup success and cancel terminal responses only when `error_code` is `WORKSPACE_ERROR_CODE_UNSPECIFIED` and `Error` is empty; reject every contradiction with nil response and stable `errWorkspaceWireResponse`.
- [x] Add deterministic four-family regressions for an allowed status with a failure error code and for an allowed status with raw `Error` text, asserting no raw sentinel is caller-reachable.
- [x] Preserve the reviewed R1 cancellation and R2 admitted-reference behavior and run every final verification command uncached where specified.
- [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_G05_3.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_cloud_G05_3.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-owned-single-request-agent-execution/09+08_workspace_wire/` to `agent-task/archive/YYYY/MM/m-iop-owned-single-request-agent-execution/09+08_workspace_wire/` 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-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

None.

## Key Design Decisions

Updated `validateWorkspaceOpenResponse`, `validateWorkspaceToolResponse`, `validateWorkspaceCancelResponse`, and `validateWorkspaceCleanupResponse` in `apps/edge/internal/service/workspace_wire.go` to enforce that accepted terminal responses (`WORKSPACE_STATUS_SUCCESS` for open/tool/cleanup, `WORKSPACE_STATUS_CANCELLED` for cancel) must also have `ErrorCode == WORKSPACE_ERROR_CODE_UNSPECIFIED` and `Error == ""`. Any contradictory outcome returns `nil, errWorkspaceWireResponse` without returning, logging, or interpolating raw error text. Added `TestWorkspaceWireRejectsContradictoryTerminalOutcome` in `apps/edge/internal/service/workspace_wire_test.go` covering all 8 contradictory status/code/error combinations across all four response families.

## Reviewer Checkpoints

- Required R3 is fixed only if an accepted open/tool/cleanup success or cancel response has `WORKSPACE_ERROR_CODE_UNSPECIFIED` and an empty `Error`.
- Every contradictory allowed-status/error-code and allowed-status/raw-error variant must return nil response plus stable `errWorkspaceWireResponse` across all four families.
- Existing blocked-tool cancellation, admitted-reference no-send, identity/status validation, stale-generation, and timeout behavior must remain intact.
- No Node concurrency, proto/generated, contract/spec, roadmap, executor, public API, or unrelated dirty-worktree changes belong to this follow-up.

## 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) |
| 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 |

## Code Review Result

### Overall Verdict

PASS

### Dimension Assessment

| Dimension | Assessment | Evidence |
|---|---|---|
| Correctness | Pass | All four validators require the expected terminal status, `WORKSPACE_ERROR_CODE_UNSPECIFIED`, and an empty raw error before returning a response. |
| Completeness | Pass | Required R3 is closed across open, tool, cancel, and cleanup without changing the preserved R1/R2 behavior. |
| Test coverage | Pass | The new eight-case matrix covers both contradictory error-code and raw-error variants for every response family and requires a nil response plus the stable sentinel. |
| API contract | Pass | Contradictory typed outcomes fail closed with `errWorkspaceWireResponse`; raw Node error content is never returned or interpolated. |
| Code quality | Pass | The change is confined to the planned validators, regression matrix, and one corrected explanatory comment; no debug output, dead code, or leftover TODO was found. |
| Implementation deviation | Pass | The implementation follows the direct-fix scope and preserves the prior cancellation, admitted-reference, generation-fence, and timeout behavior. |
| Verification trust | Pass | Fresh dependency, race, package, vet, formatting, whitespace, and focused eight-case executions all passed and matched the recorded evidence. |
| Spec conformance | Pass | The typed success/error/cancel evidence satisfies this packet's `tool-executor` contribution to S05 without claiming the aggregate Milestone Task complete. |

### Findings

None.

### Reviewer Verification

- The admission dependency check passed with exactly one active-or-archived completion candidate.
- `go test -race ./apps/edge/internal/service ./apps/node/internal/transport -run 'Test(WorkspaceWire|SessionWorkspace)' -count=1` passed.
- `go test ./apps/edge/internal/node ./apps/edge/internal/service ./apps/edge/internal/transport ./apps/node/internal/transport -count=1` passed.
- `go vet ./apps/edge/internal/node ./apps/edge/internal/service ./apps/edge/internal/transport ./apps/node/internal/transport` passed with no diagnostics.
- `git diff --check`, `gofmt -d` on both planned Go files, and a direct trailing-whitespace scan passed.
- `go test -v ./apps/edge/internal/service -run '^TestWorkspaceWireRejectsContradictoryTerminalOutcome$' -count=1` passed all eight named variants.

### Routing Signals

- `review_rework_count=2`
- `evidence_integrity_failure=false`

### Next Step

PASS: write `complete.log`, archive this task directory, and emit the `m-*` completion metadata for runtime aggregation without modifying roadmap state.
