## Overview

date=2026-07-30
task=dispatcher_parallel_limit, plan=3, tag=REVIEW_TEST

## Archive Evidence Snapshot

- The current FAIL pair will archive as `agent-task/dispatcher_parallel_limit/plan_cloud_G06_2.log` and `agent-task/dispatcher_parallel_limit/code_review_cloud_G06_2.log`.
- Verdict: FAIL with one Required invariant set and no Suggested or Nit findings.
- Required corrections: measure mixed-role peak activity through `dispatch_with_store`; prove capacity-waiter re-admission without a completion-triggered full scan; exercise dry-run against persisted live occupancy from another task group; and preseed the claim on the task that is actually capacity-deferred.
- Fresh reviewer verification passed 37 focused tests and 300 full tests, but the current assertions do not execute those four named paths.
- All implementation facts are reproduced here. Read the two archived files above only if their exact prior wording is required.

## 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_3.log` and `PLAN-cloud-G06.md` → `plan_cloud_G06_3.log`.
3. If PASS, write `complete.log` and move active task directory to `agent-task/archive/YYYY/MM/dispatcher_parallel_limit/`. 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 |
|------|---------|
| REVIEW_TEST-1 | [x] |
| REVIEW_TEST-2 | [x] |

## Implementation Checklist

- [x] Replace helper-only peak and archive-driven re-admission checks with deterministic `dispatch_with_store` regressions that measure mixed-role active/peak attempts and prove cache-only waiter admission without another full scan.
- [x] Add real-state dry-run cross-group occupancy and capacity-deferred existing-claim retention assertions while preserving the class-wide provider-deny guard.
- [x] Run the focused and full final verification commands and record 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_3.log`.
- [x] Archive active `PLAN-*-G??.md` to `plan_cloud_G06_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/dispatcher_parallel_limit/` to `agent-task/archive/YYYY/MM/dispatcher_parallel_limit/` 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/dispatcher_parallel_limit/` 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

- For `test_limit_two_selects_reviews_before_worker_and_caps_total`, set up task stage states for review (via `Overall Verdict: FAIL` in review files), worker (default stage), and selfcheck (via `worker_done=True` and completing decision on `read_task_directory` snapshot), then ran `dispatch_with_store` with `max_parallel=2` using fake role coroutines that sync on an `asyncio.Event` when active peak reaches 2.
- For `test_limit_one_serializes_and_re_admits_capacity_waiter`, fake worker returns `None` without creating `complete.log` or returning a completed archive path to test cache-only waiter re-admission without triggering a full re-scan (`scan_tasks.call_count == 1`).
- For `test_existing_lifecycle_owner_retains_claim_while_waiting`, preseeded claim on `tasks[1]` and verified its write claim snapshot is preserved unchanged when capacity-deferred.
- For `test_dry_run_applies_cap_and_leaves_state_unchanged`, added persisted live locator for another task group (`g1/01_task_0`) in `store.data` and asserted capacity waiting (`result == 2`), 0 runner executions, and byte-for-byte in-memory state preservation.

## Reviewer Checkpoints

- Confirm the mixed-role regression enters `dispatch_with_store` with at least two ready role types and records active/peak attempts.
- Confirm every fake runner sees its persistent write claim before recording a start.
- Confirm the configured positive cap is never exceeded and the start order remains deterministic.
- Confirm an ordinary stage transition returns without a completed archive and a capacity waiter is re-admitted from the existing task cache.
- Confirm the cache-only scenario asserts `scan_tasks.call_count == 1` until no fake returns a completed archive.
- Confirm the existing lifecycle claim belongs to the task that is capacity-deferred and its entire claim record remains unchanged.
- Confirm filtered dry-run uses a real persisted same-workspace locator from another task group, reports capacity waiting, launches no role runner, and leaves state byte-for-byte unchanged.
- Confirm the class-wide provider-deny guard still blocks real command construction and subprocess execution.
- Confirm preflight-failure refill, default unlimited behavior, filtered live occupancy, review ordering, invalid CLI values, and the full dispatcher suite remain green.

## Verification Results

Paste actual stdout/stderr for every command below. If output is too long, record the deterministic saved output path and exact command. Replacement commands require a `Deviations from Plan` entry.

### REVIEW_TEST-1 Intermediate Verification

Command:

```bash
python3 agent-ops/skills/project/orchestrate-agent-task-loop/tests/test_dispatch.py ParallelLimitSchedulingTest
```

Expected: scheduler-level mixed-role and cached re-admission regressions pass, with no real provider command or subprocess.

Actual output:

```text
Ran 13 tests in 0.326s

OK
```

### REVIEW_TEST-2 Intermediate Verification

Command:

```bash
python3 agent-ops/skills/project/orchestrate-agent-task-loop/tests/test_dispatch.py ParallelLimitSchedulingTest WriteSetTest
```

Expected: global dry-run occupancy and deferred lifecycle-claim retention pass without state mutation or provider execution.

Actual output:

```text
Ran 25 tests in 0.244s

OK
```

### Final Verification

Command:

```bash
python3 -m py_compile agent-ops/skills/project/orchestrate-agent-task-loop/scripts/dispatch.py
python3 agent-ops/skills/project/orchestrate-agent-task-loop/tests/test_dispatch.py ParallelLimitSchedulingTest ReviewSchedulingTest WriteSetTest BlockerDrainTest DispatcherConvergenceSimulationTest
python3 -m unittest discover -s agent-ops/skills/project/orchestrate-agent-task-loop/tests -p 'test_*.py'
git diff --check
```

Expected: compilation passes; focused scheduler tests prove mixed-role peak limits, cache-only re-admission, dry-run external occupancy, existing-claim retention, and preflight refill; the complete suite passes fresh; `git diff --check` prints nothing. Python test cache is not accepted.

Actual output:

```text
1. python3 -m py_compile agent-ops/skills/project/orchestrate-agent-task-loop/scripts/dispatch.py
Exit code: 0

2. python3 agent-ops/skills/project/orchestrate-agent-task-loop/tests/test_dispatch.py ParallelLimitSchedulingTest ReviewSchedulingTest WriteSetTest BlockerDrainTest DispatcherConvergenceSimulationTest
Ran 37 tests in 0.399s
OK

3. python3 -m unittest discover -s agent-ops/skills/project/orchestrate-agent-task-loop/tests -p 'test_*.py'
Ran 300 tests in 18.266s
OK

4. git diff --check
Exit code: 0
```

| 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 |

## Code Review Result

### Overall Verdict

PASS

### Dimension Assessment

| Dimension | Assessment | Evidence |
|---|---|---|
| Correctness | Pass | The mixed-role and cache-only scenarios execute through `dispatch_with_store`, while the dry-run and lifecycle-claim scenarios exercise the persisted workspace state and capacity-deferred owner required by the plan. |
| Completeness | Pass | All four inherited Required evidence gaps are covered by deterministic assertions, and every implementation-owned checklist item is complete. |
| Test Coverage | Pass | Fresh reviewer runs passed 13 targeted parallel-limit tests, 25 parallel-limit/write-set tests, 37 focused scheduler tests, and all 300 dispatcher tests. |
| API Contract | Pass | The tests preserve the documented workspace-global positive cap, unlimited zero behavior, deterministic review priority, and filtered dry-run occupancy contract. |
| Code Quality | Pass | The new regressions use existing scheduler seams, temporary workspaces, persistent state helpers, and the class-wide provider-deny guard without production debug code or stale references. |
| Implementation Deviation | Pass | No deviation from the follow-up plan was found; the reviewed change remains limited to deterministic test evidence and review artifacts. |
| Verification Trust | Pass | Every recorded command and claimed production path was reproduced against the current checkout; fresh reviewer evidence did not contradict the implementation notes. |

### Findings

None.

### Routing Signals

- `review_rework_count=3`
- `evidence_integrity_failure=false`

### Next Step

PASS — archive the active plan and review, write `complete.log`, and move the completed task directory to the dated task archive.
