# Batch Report — cycle 4, batch 01

**Batch**: 01
**Cycle**: 4
**Tasks**: AZ-899, AZ-900, AZ-901
**Total complexity**: 3 SP (1 + 1 + 1)
**Date**: 2026-05-26
**Commit**: `aa8b9f2` on `dev`

## Task Selection

Wave-1 cycle-4 housekeeping. All three tasks are dependency-independent (no
internal deps among themselves or against other cycle-4 work). Selected
together because:

- Each is 1 SP, fits cleanly in a single review unit.
- All three are "cycle-N process housekeeping" with no source code under
  `src/` touched — low blast radius, fast verification.
- Picking these first lets the heavier batches (AZ-894 + AZ-896 CSV path,
  AZ-895 deprecation, AZ-897 UI) start with the leftover cleared and the
  retro gate codified.

## Task Results

| Task | Status | Files Modified | Tests | AC Coverage | Issues |
|------|--------|----------------|-------|-------------|--------|
| AZ-899_architecture_compliance_baseline | Done | 1 added (`_docs/02_document/architecture_compliance_baseline.md`) | Doc inspection (no executable test) | 3/4 immediate; AC-4 defers to first cycle-4 cumulative review | None |
| AZ-900_autodev_retro_existence_gate | Done | 2 modified (`.cursor/skills/autodev/flows/existing-code.md`, `.cursor/skills/autodev/state.md`) | Doc inspection (no executable test) | 4/4 | None |
| AZ-901_evidence_out_default_path_fix | Done | 1 modified (`e2e/runner/conftest.py`), 1 deleted (`_docs/_process_leftovers/2026-05-26_evidence_out_default_path.md`) | `python -m pytest e2e/tests/performance/ -v --tb=short` → exit 0, 24 SKIPPED, evidence at `<repo_root>/e2e-results/evidence/` (AC-1) | 5/5 | None |

## File-Ownership Note

Module-layout has no Per-Component Mapping entry for pure-doc / workflow
tasks (`_docs/02_document/process_docs/`, `.cursor/skills/`). For AZ-899 and
AZ-900, OWNED was derived from the explicit files named in the task spec,
with FORBIDDEN broadly set to `src/**` (no source code touched). This is a
practical interpretation of implement-skill Step 4 for doc-only work; it
does not violate the skill's intent (no drift into unrelated source
components). AZ-901's `e2e/runner/conftest.py` falls cleanly under
`blackbox_tests` cross-cutting (Owns `e2e/**`).

## AC Test Coverage

- **AZ-899**: 3/4 ACs verified immediately by structural file inspection.
  AC-4 is a forward-looking AC that fires at the first cycle-4 cumulative
  review (next K=3 batch boundary or end-of-cycle). The baseline file now
  exists, so the cumulative-review skill will emit `## Baseline Delta`
  starting from its next run — no code or doc change in this batch can
  trigger AC-4 verification earlier.
- **AZ-900**: 4/4 ACs verified by inspection of the modified flow + state
  files. AC-4 (glob + date-range derivation) explicitly documents
  `_docs/06_metrics/retro_*.md` with `cycle_start = ` modification date of
  the latest `implementation_report_*_cycle{N-1}.md` file (with fallback to
  latest `retro_*.md` mtime, then to "yesterday").
- **AZ-901**: 5/5 ACs verified. AC-1 ran end-to-end as the per-task local
  test step.

**Total**: 12/13 ACs immediately covered. AZ-899 AC-4 is deferred-by-design
(cannot fire until the cumulative-review skill runs).

## Code Review Verdict: PASS

Lightweight inline review (per the implement skill's option for low-risk
doc-only + small e2e-infra batches). Reasoning:

- **Phase 1 (Context)**: all three task specs read; ACs walked through.
- **Phase 2 (Spec Compliance)**: AC-by-AC walkthrough above; all immediate
  ACs satisfied.
- **Phase 3 (Code Quality)**: 1 added option in `conftest.py`, multi-line
  literal; uses `pathlib.Path` already imported; help string accurately
  describes the new default. No new code in AZ-899 / AZ-900.
- **Phase 4 (Security)**: no security surface touched. `EVIDENCE_OUT`
  default change does not relax any access control or trust boundary.
- **Phase 5 (Performance)**: no hot path touched.
- **Phase 6 (Cross-task consistency)**: AZ-899 and AZ-900 both reference
  cycle-3 retro Top-3 items consistently; AZ-900's flow edit and state.md
  cross-reference both name the same gate ("Previous-Cycle Retro Existence
  Gate"). No conflicting patterns.
- **Phase 7 (Architecture)**: `e2e/runner/conftest.py` is owned by
  `blackbox_tests` cross-cutting per `module-layout.md:440`; no `src/` code
  touched; no layer rule changed; no import added.

No `@pytest.mark.xfail` decorators removed → LESSONS 2026-05-26 [testing]
gate not engaged.

## Tracker Transitions

| Ticket | Step 5 (→ In Progress) | Step 12 (→ In Testing) |
|--------|-----------------------|------------------------|
| AZ-899 | id 21, status `In Progress` (10001) confirmed | id 32, status `In Testing` (10036) confirmed |
| AZ-900 | id 21, status `In Progress` (10001) confirmed | id 32, status `In Testing` (10036) confirmed |
| AZ-901 | id 21, status `In Progress` (10001) confirmed | id 32, status `In Testing` (10036) confirmed |

Both transitions executed via Jira MCP `transitionJiraIssue` after
`getTransitionsForJiraIssue` discovery (per LESSONS 2026-05-17). Read-back
verified the new status in the transition response body.

## Leftovers / Tracker hygiene

- Closed: `_docs/_process_leftovers/2026-05-26_evidence_out_default_path.md`
  (deleted by AZ-901, AC-5).
- Still open:
  - `_docs/_process_leftovers/2026-05-11_d_cross_cve_1_opencv_pin_deferred.md`
    — gtsam numpy-2 wheel still not on PyPI; replay re-checked today;
    leftover remains open.
  - `_docs/_process_leftovers/2026-05-21_az777_complexity_override.md` —
    decision-log audit trail (not a deferred write); AZ-777 already in
    `done/`; the file says it can be deleted but is fine to keep as
    historical record. Not in scope for this batch.

## Next Batch

Batch 02 (cycle 4): AZ-894 + AZ-896 — CSV-driven replay adapter +
operator-facing format docs / example CSV. 4 SP total; AZ-894 ↔ AZ-896 are
co-dependent (either-order soft dep) so they ship together.
