"""AZ-404 — E2E replay test against the Derkachi 60 s clip. Runs the ``gps-denied-replay`` console-script (AZ-402) against the Derkachi fixture (``_docs/00_problem/input_data/flight_derkachi/``) and asserts the epic AZ-265 acceptance criteria. Per the project's E2E pattern the heavy tests are gated by ``RUN_REPLAY_E2E=1``; the lightweight AC-4a (mode-agnosticism AST scan) and AC-7 (skip-gate self-check) run unconditionally. Some ACs are SKIPPED with documented reasons until upstream work ships: * AC-3 (≤ 100 m for 80 % of ticks) — ``xfail`` until a real Topotek KHP20S30 calibration ships (camera_info.md notes the intrinsics are unknown). * AC-4b (encoder byte-equality) — ``skip`` until AZ-558 routes the C8 outbound bytes through the ``MavlinkTransport`` seam. * AC-8 / AC-9 in spec (operator workflow rehearsal) — ``skip`` until ``mock-suite-sat-service`` implements the D-PROJ-2 ingest contract. The unit-level ``_helpers.py`` tests in ``test_helpers.py`` cover AC-9 (helper L2 correctness) unconditionally.
