# Code Review Reference - REVIEW_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/11+10_workspace_command, plan=2, tag=REVIEW_API

## Archive Evidence Snapshot

- The closed plan/review pair is preserved at `agent-task/m-iop-owned-single-request-agent-execution/11+10_workspace_command/plan_cloud_G09_1.log` and `agent-task/m-iop-owned-single-request-agent-execution/11+10_workspace_command/code_review_cloud_G10_1.log`.
- The review verdict is `FAIL` with 2 Required findings and 0 Suggested findings: R1 covers incompatible Node/Edge terminal response validation, and R2 covers missing live context-cancel process-group evidence.
- Fresh reviewer runs passed the focused workspace and Node race tests, selected package regression, full Node test profile, Node vet, Edge workspace-wire tests, Darwin workspace cross-compile, contract search, and `git diff --check`; these passes do not exercise the two failed semantic preconditions.

## 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-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 active task directory to `agent-task/archive/YYYY/MM/m-iop-owned-single-request-agent-execution/11+10_workspace_command/`. If WARN/FAIL, fully write the next filesystem state required by the code-review skill.
4. If PASS, preserve first-line `milestone-task=tool-executor` 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_API-1 — Align canonical workspace terminal responses | [x] |
| REVIEW_API-2 — Prove live context cancellation owns the process group | [x] |

## Implementation Checklist

- [x] Define and exhaustively test one closed shared mapping for canonical workspace tool and cancel status/error-code/stable-message triples.
- [x] Make Node tool and cancel response construction use the shared mapping without copying raw runtime or OS errors.
- [x] Make Edge accept every canonical typed terminal response, retain bounded typed result fields, and reject identity mismatches, contradictory triples, and non-canonical raw text.
- [x] Add a deterministic live context-cancel test that starts the blocking command and descendant before cancellation and proves the full process group is gone/reaped.
- [x] Synchronize the private Edge-Node wire contract with the canonical triples and raw-error fence.
- [x] Run dependency, focused race, full Node/Edge, vet, Darwin compile, contract-search, and whitespace verification with fresh results.
- [x] Fill every implementation-owned section in `CODE_REVIEW-cloud-G08.md` with actual changes, decisions, deviations, and command 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-cloud-G08.md` to `code_review_cloud_G08_2.log`.
- [x] Archive active `PLAN-local-G08.md` to `plan_local_G08_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/m-iop-owned-single-request-agent-execution/11+10_workspace_command/` to `agent-task/archive/YYYY/MM/m-iop-owned-single-request-agent-execution/11+10_workspace_command/` and update this checklist at the final archive path.
- [x] If PASS, preserve and report `milestone-task=tool-executor` 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. Implementation executed all plan items, checklist requirements, and verification commands as written.

## Key Design Decisions

- Created a shared package `packages/go/workspaceprotocol` owning canonical `(Status, ErrorCode) -> (message, ok)` terminal authorities (`ToolTerminal`, `CancelTerminal`, `OpenTerminal`, `CleanupTerminal`) shared by both Node response construction and Edge response validation.
- Updated `apps/node/internal/node/workspace_handler.go` to construct all workspace terminal error messages strictly using the shared authority without leaking raw OS or runtime error details.
- Updated `apps/edge/internal/service/workspace_wire.go` response validators to require exact canonical triples from `workspaceprotocol`, allowing valid typed non-success responses (preserving stdout, stderr, exit code, and duration fields) while rejecting contradictory pairs, unrecognized status/code combinations, and raw text leakage as `errWorkspaceWireResponse`.
- Updated `apps/node/internal/workspace/command_executor_test.go` `TestCommandExecutorTimeoutAndContextCancel` to assert active live context cancellation after launching a process and descendant (`group` mode), verifying `CANCELLED/CANCELLED` result and process group termination/reap.
- Updated `agent-contract/inner/edge-node-runtime-wire.md` to document the closed `workspaceprotocol` authority, canonical triples, raw-error fence, and bounded typed field preservation.

## Reviewer Checkpoints

- Confirm Node response construction and Edge validation use the same closed authority for exact tool/cancel status, error-code, and stable-message triples.
- Confirm canonical non-zero, timeout, cancellation, unsupported, invalid, and not-found responses preserve bounded typed fields through Edge, while identity mismatch, contradictory triples, and raw sentinel text return only the stable wire error.
- Confirm context cancellation occurs after the command and descendant start, terminates the full process group, returns one typed `CANCELLED` result, and leaves no descendant alive or unreaped.
- Confirm fixed executable/args, admitted descriptor cwd, minimal environment, output cap, and explicit cancellation isolation are unchanged.

```text
agent-contract/inner/edge-node-runtime-wire.md:92:- `Workspace*Response`: returns closed status/error-code enums and bounded content/list/stdout/stderr/exit/truncation/duration fields. Response construction and validation consume one closed `workspaceprotocol` authority for canonical status, error-code, and stable generic message triples (`SUCCESS/UNSPECIFIED/""`, `UNSUPPORTED/NOT_READY/"workspace runtime not ready"`, `UNSUPPORTED/UNSUPPORTED/"workspace operation unsupported"`, `ERROR/NOT_FOUND/"workspace entry not found"` or `"workspace command not found"`, `ERROR/INVALID_REQUEST/"workspace request rejected"` or `"workspace cancellation rejected"`, `TIMEOUT/TIMEOUT/"workspace command timed out"`, `CANCELLED/CANCELLED/"workspace command cancelled"`, `ERROR/INTERNAL/"workspace operation failed"`). Typed non-success outcomes (non-zero exit, timeout, cancellation) retain bounded output, exit-code, and duration fields across Edge validation; contradictory triples, unknown combinations, or raw OS/runtime error text fail closed as stable transport error without leaking Node text. Transport and handler failures use stable generic errors and do not echo workspace paths, command details, content, environment values, or credentials.
packages/go/workspaceprotocol/terminal.go:7:// ToolTerminal returns the exact canonical message for a tool status and error code pair.
packages/go/workspaceprotocol/terminal.go:8:// Returns (message, true) for valid canonical pairs, or ("", false) if the pair is invalid.

## Code Review Result

- **Overall Verdict:** PASS
- **Finding Counts:** Required 0, Suggested 0, Nit 0

### Dimension Assessment

| Dimension | Assessment | Evidence |
|-----------|------------|----------|
| Correctness | Pass | Node response construction and Edge response validation consume the same closed `workspaceprotocol` authority, and live context cancellation terminates the owned process group. |
| Completeness | Pass | REVIEW_API-1 and REVIEW_API-2, including contract synchronization and all planned verification commands, are complete. |
| Test coverage | Pass | Shared terminal cases, Node command/cancel handling, Edge canonical and contradictory response paths, and live descendant cancellation are covered by fresh race-enabled tests. |
| API contract | Pass | Canonical typed non-success responses preserve bounded typed fields across the private Edge-Node boundary while identity, triple, and raw-text violations fail closed. |
| Code quality | Pass | The shared authority removes producer/consumer duplication and introduces no debug output, dead code, or unrelated behavioral change in the reviewed scope. |
| Implementation deviation | Pass | No deviation from the routed follow-up plan or its write boundary was found. |
| Verification trust | Pass | Fresh reviewer runs matched the implementation record for dependency, focused race, full Node/Edge, vet, Darwin compile, contract search, and whitespace checks. |
| Spec conformance | Pass | The implementation satisfies SDD S05 evidence for typed workspace success, failure, timeout, cancellation, process ownership, and synchronized private-wire behavior. |

### Findings

None.

### Routing Signals

- `review_rework_count=1`
- `evidence_integrity_failure=false`

### Next Step

- PASS: write `complete.log`, archive the active pair, and move the completed split task under `agent-task/archive/2026/08/` while preserving Milestone completion metadata for runtime aggregation.
