# Implementation Report

**Feature**: Blackbox and e2e test implementation
**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

## Batch Outcomes

| Batch | Tasks | Code Review | Tests |
|-------|-------|-------------|-------|
| 11 | AZ-233_test_infrastructure | PASS | 4 passed |
| 12 | AZ-234, AZ-235, AZ-236, AZ-237 | PASS | 18 passed |
| 13 | AZ-238, AZ-239 | PASS | 25 passed |

## 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.
