+# Batch Report
+
+**Batch**: 11
+**Tasks**: AZ-233_test_infrastructure
+**Date**: 2026-05-05
+
+## Task Results
+
+| Task | Status | Files Modified | Tests | AC Coverage | Issues |
+|------|--------|---------------|-------|-------------|--------|
+| AZ-233_test_infrastructure | Done | 18 files plus task archive | 4 passed | 4/4 ACs covered | None |
+
+## AC Test Coverage: All covered
+
+- AC-1: `test_replay_environment_reports_missing_prerequisites_as_blocked`
+- AC-2: `test_satellite_cache_stub_is_deterministic_and_records_interactions`
+- AC-3: `test_runner_executes_all_required_groups_and_writes_reports`
+- AC-4: `test_runner_executes_all_required_groups_and_writes_reports`, `test_runner_keeps_generated_artifacts_run_scoped`
+
+## Code Review Verdict: PASS
+## Auto-Fix Attempts: 0
+## Stuck Agents: None
+
+## Verification
+
+- `python3 -m pytest tests/blackbox/test_infrastructure.py`: 4 passed.
+- `python3 -m e2e.replay.run_replay --output-dir /tmp/gpsd-blackbox-smoke`: generated CSV and Markdown replay evidence.
+
+## Next Batch: AZ-234, AZ-235, AZ-236, AZ-237

+# Code Review Report
+
+**Batch**: AZ-233_test_infrastructure
+**Date**: 2026-05-05
+**Verdict**: PASS
+
+## Findings
+
+| # | Severity | Category | File:Line | Title |
+|---|----------|----------|-----------|-------|
+
+No findings.
+
+## Review Notes
+
+- Spec compliance: AC-1 through AC-4 are covered by `tests/blackbox/test_infrastructure.py`.
+- Scope: changes stay within blackbox/e2e test-support ownership plus replay container and compose wiring.
+- Security quick-scan: no subprocess shell execution, dynamic evaluation, hardcoded secrets, or network calls were introduced.
+- Architecture: test infrastructure imports only its own `e2e.replay` package and does not import runtime component internals.
