## Overview

date=2026-08-03
task=m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding, plan=5, tag=REVIEW_REVIEW_REVIEW_REVIEW_API

## Archive Evidence Snapshot

- Prior plan: `agent-task/m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding/plan_cloud_G07_4.log`.
- Prior review: `agent-task/m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding/code_review_cloud_G07_4.log`.
- Verdict: FAIL with 1 Required, 0 Suggested, and 0 Nit findings; `review_rework_count=4`, `evidence_integrity_failure=false`.
- Required scope: make containment comparison correct when the canonical workspace root is `/`, and add permanent existing-target plus non-parent-capable root-workspace regressions while retaining fresh-parent and symlink-escape coverage.
- Affected files: `apps/edge/internal/openai/workspace_tool_codec.go` and `apps/edge/internal/openai/workspace_tool_binding_test.go`.
- Fresh evidence: dependency, focused, SDD-expanded race, Edge-wide, vet, formatting, and diff checks pass on unchanged owned sources; the exact generated-guard probe with `IOP_WORKSPACE_CWD=/` and existing relative target `tmp` prints `iop: path escapes workspace root` and exits 1.
- Roadmap carryover: Milestone task `artifact-pair` and approved SDD scenario S06 remain unsatisfied for canonical containment across every API-admitted absolute workspace.

## 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-G03.md` → `code_review_cloud_G03_5.log` and `PLAN-cloud-G03.md` → `plan_cloud_G03_5.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/08+02,04,06_workspace_binding/`. 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 Make Root-Workspace Containment Correct | [x] |

## Implementation Checklist

- [x] Make containment guard path joining and prefix comparison correct for canonical workspace `/`, add existing-target and non-parent-capable root-workspace regressions, and obtain clean dependency, focused, SDD-expanded race, all-Edge, vet, formatting, and diff evidence.
- [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_G03_5.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_cloud_G03_5.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/08+02,04,06_workspace_binding/` to `agent-task/archive/YYYY/MM/m-iop-hot-path-one-shot-execution/08+02,04,06_workspace_binding/` 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

- In `synthesizeContainmentGuard`, defined `IOP_WS_PREFIX` dynamically based on whether `IOP_WS_ROOT` is `/` (`""` if `/`, `$IOP_WS_ROOT` otherwise).
- Updated shell `case` pattern comparison from `"$IOP_WS_ROOT"/*` to `"$IOP_WS_PREFIX"/*` so `"$IOP_WS_TARGET/"` is matched against `/*` when `IOP_WS_ROOT` is `/`, eliminating double-slash pattern prefix mismatch while retaining exact root boundary fencing for non-root workspaces.
- Added tests in `TestWorkspaceContainmentGuard` verifying that both existing relative targets and non-parent-capable targets with existing immediate parents under canonical workspace root `/` pass evaluation, while preserving non-root fresh parent admission and symlink escape rejection.

## Reviewer Checkpoints

- Canonical workspace `/` admits an existing relative target and a non-parent-capable missing target whose immediate parent exists.
- Non-root parent-capable fresh paths remain admitted, while non-parent-capable missing immediate parents remain rejected.
- Existing final and ancestor symlinks that canonicalize outside the workspace still fail.
- Guard-affecting output remains covered by the issued payload correlation digest, and mutation makes the receipt unmatched.
- Hermetic tests evaluate only generated guards and never execute a caller workspace command.
- Every required verification command passes on one checkout and the recorded output is verbatim.

## Verification Results

### Dependency verification

```bash
test -f agent-task/m-iop-hot-path-one-shot-execution/02+01_preset_generation/complete.log || test -f agent-task/archive/2026/08/m-iop-hot-path-one-shot-execution/02+01_preset_generation/complete.log
test -f agent-task/m-iop-hot-path-one-shot-execution/04+02,03_preset_model_authorization/complete.log || test -f agent-task/archive/2026/08/m-iop-hot-path-one-shot-execution/04+02,03_preset_model_authorization/complete.log

## Code Review Result

### Overall Verdict

PASS

### Dimension Assessment

| Dimension | Assessment | Evidence |
|-----------|------------|----------|
| Correctness | Pass | The root-aware prefix makes canonical workspace `/` accept existing and non-parent-capable descendants while the existing nearest-ancestor and symlink fencing remain intact. |
| Completeness | Pass | The inherited root-workspace Required finding is fixed, both requested permanent regressions exist, and every active-plan implementation item is complete. |
| Test coverage | Pass | The containment matrix covers root existing and existing-parent targets, non-root fresh parents, missing immediate parents, and final/ancestor symlink escapes. |
| API contract | Pass | Every absolute workspace admitted by `validateWorkspaceForRoute`, including `/`, now preserves the SDD S06 no-escape containment behavior for the owned compiler/codec boundary. |
| Code quality | Pass | The change is localized, deterministic, formatted, and contains no debug output, stale TODOs, or dead-code additions. |
| Implementation deviation | Pass | The implementation and tests match the active plan without unrelated changes in the owned files. |
| Verification trust | Pass | Fresh dependency, focused, SDD-expanded race, Edge-wide, vet, formatting, and diff checks all passed; owned-source hashes were unchanged across verification. |
| Spec conformance | Pass | The owned workspace binding evidence satisfies the S06 canonical-to-actual mapping and containment requirement without executing a caller workspace command. |

### Findings

None.

### Reviewer Verification Evidence

- Exact predecessor completion probes: PASS with no output.
- `go test -count=1 ./apps/edge/internal/openai -run 'TestWorkspace(Tool|Command|Binding|Operation|Containment)'`: PASS (`ok`, 0.342s).
- `go test -race -count=1 ./packages/go/streamgate ./packages/go/config ./apps/edge/internal/openai ./apps/edge/internal/service`: PASS (`streamgate` 2.041s, `config` 1.629s, `openai` 9.216s, `service` 7.019s).
- Executable-`TMPDIR` `go test -count=1 ./apps/edge/...`: PASS for every Edge package.
- `go vet ./apps/edge/...`, `gofmt -d` on both owned source files, and `git diff --check`: PASS with no output.
- Reviewed-source SHA-256 values were unchanged before and after verification: `838399f2...72e6` and `8013d872...8188`.
- Repository-native Edge/provider smoke, caller workspace command execution, and full-cycle external agent execution were not run because this split child owns an isolated compiler/codec boundary and the active plan explicitly excludes production coordinator integration and caller workspace execution.

### Routing Signals

`review_rework_count=4`

`evidence_integrity_failure=false`

### Next Step

PASS: archive the active pair, write `complete.log`, and move the completed task directory to the monthly task archive.
