# Code Review Reference - REFACTOR

> **[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.
> Follow the ownership table at the bottom of this file for which sections you own.

## Overview

task=dispatcher_workspace_ownership, plan=0, tag=REFACTOR

## 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_0.log` and `PLAN-cloud-G08.md` → `plan_cloud_G08_0.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/dispatcher_workspace_ownership/`. 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>`, report completion event metadata. Roadmap state check and `update-roadmap` calls are runtime responsibilities.
5. Check applicable `Review-Only Checklist` items at the final `.log` location before reporting.

## Implementation Item Completion

| Item | Status |
|------|---------|
| REFACTOR-1 | [x] |
| REFACTOR-2 | [x] |
| REFACTOR-3 | [x] |

## Implementation Checklist

- [x] Bind dispatcher state, locator records, process markers, and liveness recovery to canonical physical workspace identity.
- [x] Enforce persistent Modified Files Summary claims before worker/selfcheck/review admission, wait on collisions, retain across follow-ups/restarts, and release only after verified completion.
- [x] Update project dispatcher policy and mocked regression/convergence tests for workspace isolation, fail-closed write sets, claim lifecycle, and safe parallelism.
- [x] Run deterministic syntax and full dispatcher unit verification.
- [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_G08_0.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_cloud_G08_0.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/dispatcher_workspace_ownership/` to `agent-task/archive/YYYY/MM/dispatcher_workspace_ownership/` and update this checklist at the final archive path.
- [ ] If PASS and task group is `m-<milestone-slug>`, report completion event metadata for runtime, without modifying roadmap or directly calling `update-roadmap`.
- [ ] If PASS for split work, remove empty active parent `agent-task/{task_name}/` 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

No implementation-scope or verification-command deviation. During review, the original workspace-ownership criterion exposed two additional resume/evidence seams, so those seams and their regressions were corrected within REFACTOR-1. The planned unit command was run exactly after the review fixes. Because its lifecycle-fixture output is verbose, the invocation used shell redirection to preserve complete output at `/tmp/iop-dispatcher-workspace-ownership-review-unittest.log`.

## Key Design Decisions

- State records, locator paths, locator metadata, and process markers are bound to the canonical physical workspace id before liveness evidence is accepted.
- Laguna recovery and Pi invocation independently revalidate locator, stream, and native-session ownership at their final resume seams, so a foreign failed locator cannot bypass the liveness gate.
- The write-claim ledger is global to one physical workspace rather than one task group. Ordered admission updates it atomically under the existing dispatcher lock.
- A task owns its claim through all execution stages and follow-up generations. A conflicting expansion keeps the prior claim unchanged, while verified archive completion releases it.
- Active legacy work without a valid file list adopts an exclusive workspace claim, preventing unsafe guesses until the task is repaired or verified complete.
- Missing, duplicate, broad, directory, wildcard, outside-workspace, or otherwise invalid modified-file tables fail closed; dry-run previews admission without mutating state.

## Reviewer Checkpoints

- Reject foreign-workspace locators before consulting PID, process-marker, native-session, or stream evidence.
- Verify that claim acquisition is atomic per physical workspace and collision reports identify both owner and canonical path.
- Verify that a claim survives worker, self-check, review, retry, restart, and compatible follow-up transitions, then releases only after verified completion.
- Verify that disjoint tasks still run in parallel and separate physical worktrees/clones use independent state and claim ledgers.
- Verify that all provider-facing paths remain mocked in tests.

## Verification Results

### Python bytecode compilation

Command:

```bash
python3 -m py_compile agent-ops/skills/project/orchestrate-agent-task-loop/scripts/dispatch.py agent-ops/skills/project/orchestrate-agent-task-loop/tests/test_dispatch.py
```

Actual output:

```text
Process exited with code 0
stdout: <empty>
stderr: <empty>
```

### Dispatcher unit suite

Command:

```bash
python3 -m unittest discover -s agent-ops/skills/project/orchestrate-agent-task-loop/tests -p 'test_dispatch.py'
```

Actual output:

The planned command exited `0`. Its captured result ended with:

```text
----------------------------------------------------------------------
Ran 219 tests in 13.584s

OK
```

The complete capture is `/tmp/iop-dispatcher-workspace-ownership-review-unittest.log`. Capture command and actual tail:

```text
$ python3 -m unittest discover -s agent-ops/skills/project/orchestrate-agent-task-loop/tests -p 'test_dispatch.py' > /tmp/iop-dispatcher-workspace-ownership-review-unittest.log 2>&1
----------------------------------------------------------------------
Ran 219 tests in 13.584s

OK
```

## 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) |
| Roadmap Targets | Fixed at stub creation from plan when present | Implementing agent must not modify; code-review copies it into `complete.log` as `Roadmap Completion` only on PASS |
| 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 |
| Agent UI Completion | Mixed | Present only for plan-required agent-ui code work; implementing agent fills actual evidence, review agent applies `구현됨` status/evidence update on PASS and copies the section into `complete.log` |
| 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

- Correctness: Pass — workspace-owned liveness, recovery, final resume seams, and persistent write-claim admission match the plan's invariants.
- Completeness: Pass — all three implementation items and their required policy/test updates are present.
- Test coverage: Pass — foreign/current/legacy locator ownership, Laguna/Pi resume boundaries, claim collision/lifecycle, restart behavior, and disjoint parallelism are covered.
- API contract: Pass — no public symbol was removed, and the project dispatcher contract now describes the enforced runtime behavior.
- Code quality: Pass — ownership and claim validation are centralized, fail closed, and integrated through existing state and scheduler boundaries.
- Implementation deviation: Pass — review fixes remained within REFACTOR-1 and no out-of-scope product, common-rule, or roadmap files changed.
- Verification trust: Pass — bytecode compilation and all 219 dispatcher tests passed from the reviewed working tree.

### Findings

None.

### Routing Signals

- `review_rework_count=0`
- `evidence_integrity_failure=false`

### Next Step

Archive the reviewed pair, write `complete.log`, and move the completed task to its dated archive.
