From bfcac2cb9f1bb5fbd2e1b750c3435a8ea6cc01f6 Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Sat, 23 May 2026 15:08:34 +0300 Subject: [PATCH] [AZ-839] [AZ-835] operator_pre_flight_setup real fixture (E-AZ-835 C3) Replace the placeholder operator_pre_flight_setup pytest fixture (the mkdir stub at tests/e2e/replay/conftest.py:293-310) with a real driver that wires C1 (AZ-836 RouteSpec) + C2 (AZ-838 SatelliteProviderRoute Client) + C11 (AZ-316 HttpTileDownloader) + C10 (AZ-322 Descriptor Batcher) end-to-end and yields a typed PopulatedC6Cache. AZ-306 FAISS sidecar triple-consistency is verified post-rebuild via a caller- supplied descriptor_index_factory; partial sidecars are cleaned up on failure (AC-7) while pre-existing warm-cache files are preserved. Algorithm lives in tests/e2e/replay/_operator_pre_flight.py with pure dependency injection so the AC-8 unit suite (11 tests covering happy / transient-retry / terminal-failure / validation-error / tamper-detection / cleanup-on-failure) runs against stubs and the AC-9 Tier-2 integration test runs the same algorithm against the real Jetson harness. The conftest fixture skip-gates on RUN_REPLAY _E2E + SATELLITE_PROVIDER_URL/API_KEY + BUILD_FAISS_INDEX + GPS_DENIED_OPERATOR_CONFIG_PATH and wires deps through the existing runtime_root factories. Supersedes AZ-777 Phase 3.

Context loading | AZ-839 task spec + dependencies (AZ-836 RouteSpec, AZ-838 SatelliteProviderRouteClient, AZ-322 DescriptorBatcher, AZ-316 HttpTileDownloader, AZ-306 FaissDescriptorIndex) all read prior to implementation. The FAISS triple-consistency check was verified against `faiss_descriptor_index._load()` source. | +| 2. Spec compliance | AC-3 / AC-4 / AC-5 / AC-6 / AC-7 / AC-8 directly covered. AC-1 / AC-2 / AC-9 deferred to Tier-2 harness (gated tests exist). **No Medium / High findings.** | +| 3. Code quality | Driver is one function with one responsibility (orchestrate the C1+C2+C11+C10 pipeline); SRP upheld. Each helper is named after its job (`_seed_route_with_retry`, `_route_bbox`, `_cleanup_partial_sidecars`). Functions ≤ ~80 lines. Explicit exception filtering (`RouteValidationError`, `RouteTerminalFailureError`, `RouteTransientError`) — no bare except. Tests follow Arrange/Act/Assert with comment markers per `coderule.mdc`. | +| 4. Security quick-scan | JWT consumed via env-sourced kwargs, never logged. The cleanup path does not unlink files outside the `cache_root/` tree (only the three sidecar paths the driver was handed). | +| 5. Performance scan | O(n) over waypoints (n ≤ 10 by AZ-836's `max_waypoints` default). No new N+1. The retry ladder respects the AZ-838 `_DEFAULT_BACKOFF_SCHEDULE_S` cadence verbatim. | +| 6. Cross-task consistency | Single-task batch — N/A. | +| 7. Architecture compliance | `_operator_pre_flight.py` lives under `tests/e2e/replay/` (test infrastructure). Imports only from C10 / C11 / C6 public surfaces and from `replay_input.tlog_route.RouteSpec` (Adapter layer per `module-layout.md`). The conftest fixture wires deps via the existing `runtime_root` factories — does not import concrete impl modules directly. No cross-component imports between C-prefixed components. No new cyclic dependencies. ADR check skipped (no ADRs directory). | + +### Findings + +**F1 (Low) — `_default_tile_decoder` lives in conftest.py** + +`_default_tile_decoder` (JPEG → CHW float32 numpy) lives in the +test conftest. The same primitive will be needed by the eventual +replay-mode operator binary (Epic AZ-835 follow-up); promoting it +into `runtime_root` is out of scope for AZ-839 (which is "wire C10 +into a real fixture"), but it is on the path of AZ-840 / AZ-841. +**Recommendation**: leave as-is for AZ-839; revisit during AZ-840. + +**F2 (Low) — `_resolve_replay_descriptor_dim` is NetVLAD-only** + +The NetVLAD descriptor dim resolver pinned at `c2_vpr/config.py:67` +matches the AZ-839 task spec's "Out of scope" §, but it skips the +fixture if any other backbone is configured. **Recommendation**: +when AZ-840 needs a non-NetVLAD backbone, extend the resolver +table per strategy. Tracking via the AZ-840 spec is sufficient. + +### Deltas vs. spec + +None. The task spec mentions `download_for_bbox`; the actual +production method is `download_tiles_for_area` (a `bbox`-aware +single-zoom request via `DownloadRequest`). The spec was informal +on the method name; the production API (which has been stable +since AZ-316) was honoured. + +## Notes for follow-up + +- AZ-840 (e2e orchestrator test) consumes this fixture.
