[AZ-233] Update Docker Compose and enhance test documentation

- Modified the Docker Compose configuration to include an input root for replay tests and added an environment variable for enabling SITL.
- Enhanced documentation for various testing processes, including the addition of a Runtime Completeness Decomposition Gate and clarifications on internal module testing requirements.
- Updated the implementation completeness report to reflect the current state and added new test cases for performance and resilience scenarios.

+Verifies the implemented unit, integration, blackbox, and e2e tests pass before proceeding to spec and documentation sync. This is a hard product gate, not a harness-smoke gate: e2e/blackbox tests must exercise the actual implemented system through public runtime boundaries and compare actual outputs against `_docs/00_problem/input_data/expected_results/results_report.md` or referenced machine-readable expected-result files. Stubs are allowed only for external systems outside the product boundary; missing internal product implementation must fail or block the gate and send the flow back to Implement.

 - Derkachi project data supports synchronized video/IMU/GPS trajectory replay for FT-P-03 and NFT-PERF-02.
 - Derkachi project data is calibration-limited: raw camera intrinsics, lens distortion, and camera-to-body transform are still required before final absolute accuracy thresholds can be treated as production acceptance.
 - Phase 3 must validate camera calibration inputs and public/calibrated dataset acquisition before FT-P-03, FT-P-04, and NFT-PERF-02 can be used for final signoff.
+- Cycle 1 Docker replay smoke evidence currently passes blackbox, performance, resilience, and security infrastructure scenarios; Jetson resource evidence remains a target-hardware release gate and is reported as blocked on local runners.

 ## Summary
 
-All product implementation tasks for cycle 1 are implemented or have explicit runtime prerequisite boundaries. The remediation tasks close the previously identified gaps in native VIO selection, local descriptor/index VPR retrieval, and computed anchor matching/geometry verification.
+Product implementation was previously marked complete, but Step 11 exposed a false-positive gate: tests passed against scaffold/fake contract behavior while the actual A-Z runtime path, especially real VIO execution, is not implemented. Product implementation must return to Step 7 and create remediation tasks before downstream test gates can be trusted.

+- VIO currently exposes `NativeVioBackend` behind the `VioBackend` protocol, but the production/native engine is not actually integrated. This is a scaffold, not product-complete VIO.

 - Anchor verification now computes matcher evidence from frame/tile keypoints through `KeypointRansacMatcher`, reports runtime/quality metrics, and routes computed evidence through the existing freshness, provenance, inlier, MRE, and homography gates.

+**Cycle**: 1
+**Date**: 2026-05-05
+**Status**: Complete
+
+## Summary
+
+Greenfield test implementation completed the blackbox/e2e replay harness and all test tasks for still-image replay, synchronized VIO replay, satellite-anchor/cache security, MAVLink blackout/spoofing, cold-start/restart, Jetson resource, and FDR endurance scenarios.
+
+- Total test tasks completed: 7
+- Completed batches: 3
+- Blocked tasks: 0
+- Code review verdicts: PASS for all batch reviews and cumulative review
+- Focused verification: 25 blackbox tests passed
+- Full-suite gate: handed off to Step 11 (`test-run`) per implement Step 16

+## Acceptance Coverage
+
+All acceptance criteria documented in the test implementation task specs are covered by focused blackbox tests recorded in the batch reports:
+
+- Replay infrastructure starts or reports blocked prerequisites, uses deterministic stubs, discovers required scenario groups, and writes CSV/Markdown evidence.
+- Still-image replay validates WGS84 expected-coordinate fixtures, confidence/source-label fields, latency percentiles, and dropped-frame metrics.
+- Synchronized VIO replay validates Derkachi alignment gates, public VIO replay output, and calibration/public-dataset blocked prerequisites.
+- Satellite-anchor/cache tests validate retrieval evidence, geometry verification, invalid cache rejection, no in-flight external access, and storage-budget evidence.
+- MAVLink blackout/spoofing tests validate dead-reckoned/no-fix transitions, safe `GPS_INPUT` emission behavior, unauthorized source rejection, and QGC/FDR status visibility.
+- Restart/resource tests validate relocalization triggers, first-fix trial aggregation, Jetson blocked prerequisites, resource metrics, and FDR rollover evidence.
+
+## Review Summary
+
+- Batch reviews: `_docs/03_implementation/reviews/batch_11_review.md` through `_docs/03_implementation/reviews/batch_13_review.md`
+- Cumulative review: `_docs/03_implementation/reviews/cumulative_review_batches_11-13_tests_report.md`
+- Auto-fix attempts: 0 across all test batches
+- Stuck agents: none
+
+## Verification
+
+- `python3 -m pytest tests/blackbox/test_infrastructure.py`: 4 passed.
+- `python3 -m pytest tests/blackbox`: 18 passed after batch 12.
+- `python3 -m pytest tests/blackbox`: 25 passed after batch 13.
+- `python3 -m e2e.replay.run_replay --output-dir /tmp/gpsd-blackbox-smoke`: generated CSV and Markdown replay evidence.
+- Formatter/linter CLIs declared in `pyproject.toml` were unavailable in this interpreter: `black` and `ruff` modules were not installed.
+
+## Next Step
+
+Autodev may advance to Step 11, Run Tests. The full-suite gate is intentionally owned by Step 11 to avoid duplicating the test-run skill's diagnosis and reporting workflow.
