+# 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.

+
+## 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.
