That ticket has been closed Won't Fix. This task replaces it with the correct scope and API. + +## Outcome + +1. **API-correct C++ binding rewrite**: rewrite `_native/okvis2_binding.cpp` against the actual OKVIS2 upstream API: + - Headers: `okvis/ThreadedSlam.hpp`, `okvis/ViParametersReader.hpp`, `okvis/Parameters.hpp`, `okvis/ViInterface.hpp`. + - Construct `okvis::ThreadedSlam(parameters, dBowDir)` after reading `yaml_config_` via `okvis::ViParametersReader(yaml).getParameters(parameters)`. + - Subscribe to `setOptimisedGraphCallback(...)` with a lambda whose signature is `void(const State&, const TrackingState&, std::shared_ptr>, std::shared_ptr)`. Fill `latest_output_` under `output_mtx_` from `State::T_WS`, `v_W`, `b_g`, `b_a`, `omega_S`, `timestamp`, `isKeyframe`; derive `tracked_features` + `mean_parallax` from `TrackingState`. + - Convert numpy uint8 frames to `cv::Mat` (re-using the existing `py::array_t` no-copy buffer view) and call `addImages(okvis_time, {0: cv_mat})`. + - Forward IMU via `addImuMeasurement(okvis_time, Eigen::Vector3d(alpha), Eigen::Vector3d(omega))`. + - Map `okvis::TrackingQuality` (Good/Marginal/Lost) onto the binding's `HealthState` enum. + - Reset: re-construct `ThreadedSlam` from the same `parameters` and re-subscribe the callback (OKVIS2 has no in-place reset). + +2. **6×6 covariance extraction**: ViInterface does not expose the marginalisation block directly. Two options: + - (a) Add a tiny upstream patch to `ThreadedSlam` exposing `ViSlamBackend::computeCovariance(StateId)`; document the patch under `cpp/okvis2/patches/`. + - (b) Best-effort proxy: emit a fixed-rank diagonal scaled by feature count / tracking-quality until the upstream patch lands. Mark the AC-1.4 covariance honesty test as `xfail(strict=True)` until option (a) is in. + +3. **CMake glue**: extend `cpp/okvis2/CMakeLists.txt` to link OpenCV (cv::Mat is used in the binding). Verify Eigen pin alignment with GTSAM + VINS-Mono (AZ-593). + +4. **CI workflow**: in `.github/workflows/ci.yml`, add `apt install -y libceres-dev libbrisk-dev libdbow2-dev libsuitesparse-dev libgflags-dev libgoogle-glog-dev libopencv-dev libboost-filesystem-dev libatlas-base-dev libeigen3-dev` to the Linux runner setup step. Flip `-DBUILD_OKVIS2=OFF` to `-DBUILD_OKVIS2=ON` for the `airborne` + `research` matrix kinds. + +5. **DBoW2 vocab artifact**: package `small_voc.yml.gz` next to the .so install location. Two options: + - (a) Vendor inside the repo (small file, ~3MB — but ROS users typically download separately). + - (b) Fetch at CI time via a pinned URL from a OKVIS2 release artifact mirror; user decides at scheduling time. + +6. **Tier-1 integration test**: `tests/integration/c1_vio/test_az332_okvis2_real_binding.py` with `@pytest.mark.skipif(not _okvis2_binding_present())`. Sanity-check that the binding loads and processes a 60-frame EuRoC-class fixture without throwing; does NOT validate accuracy (Tier-2). + +7. **Tier-2 Jetson validation** (AC-9 of original AZ-332): run honest 6×6 covariance validation against Derkachi-class fixtures on real Jetson Orin. p95 ≤ 80 ms; p50 ≤ 25 ms per the original NFR-perf budget.

Pre-process upstream sources via CMake `configure_file` to redirect ROS headers to the stubs. + +4. **C++ binding rewrite**: replace `_native/vins_mono_binding.cpp` skeleton with real `Estimator` + `FeatureTracker` wiring. API surface: + - Construct `feature_tracker::FeatureTracker` + `vins_estimator::Estimator` after parsing `yaml_config_` via VINS-Mono's `readParameters()` / equivalent. + - In `add_frame(image)`: call `feature_tracker_.readImage(image_8uc1, ts_seconds)`, retrieve the resulting feature observations, feed them into `estimator_.processImage(image_msg, header)` (mirroring the upstream `feature_tracker_node.cpp` / `estimator_node.cpp` flows but without ROS message types). + - In `add_imu(ts, accel, gyro)`: `estimator_.processIMU(ts, alpha, omega)`. + - Periodically (or per-frame) call `estimator_.processMeasurements(...)` and `estimator_.solveOdometry()` to drive the sliding-window optimisation. + - Extract output: read `estimator_.Ps[WINDOW_SIZE]` (position), `estimator_.Rs[WINDOW_SIZE]` (rotation), `estimator_.Bas[WINDOW_SIZE]` / `estimator_.Bgs[WINDOW_SIZE]` (biases). Pose covariance from `estimator_.last_marginalization_info`. + - Reset: `estimator_.clearState()` + `estimator_.setParameter()`. + +5. **CMake glue**: extend `cpp/vins_mono/CMakeLists.txt` to link the upstream + stub libs against pinned Ceres + OpenCV ≥ 4.2 + Eigen ≥ 3.4. **Pin alignment**: ensure Eigen + Ceres pins match AZ-592 (OKVIS2 Tier-2) to avoid ABI conflict in the research binary which links both. + +6. **CI workflow**: gate `BUILD_VINS_MONO=ON` on the `research` / `comparative-study` CI matrix kind only (NOT the airborne kind — `ci/sbom_diff.py` enforces).

The per-component factories are stable surfaces and should not change shape inside this task. +- Operator binary strategy registrations beyond the placeholder — the operator binary's actual strategy use is handled by direct factories today (`build_flights_api_client`, etc.) which compose_operator already consumes correctly. +- Replay-branch additions — `compose_root`'s replay path uses `pre_constructed`, which is orthogonal to the registry-driven path this task fixes. + +## Acceptance Criteria + +**AC-1: Bootstrap populates the airborne registry with 7 component slots** +Given a fresh process where `_STRATEGY_REGISTRY` is empty +When `register_airborne_strategies()` is called +Then `list_registered_strategies("c1_vio")` returns `["klt_ransac", "okvis2", "vins_mono"]` (sorted); same exhaustive list for c2_vpr / c2_5_rerank / c3_matcher / c3_5_adhop / c4_pose / c5_state; every registered factory carries `tier="airborne"`. + +**AC-2: compose_root reaches takeoff with default strategies + klt_ransac** +Given `register_airborne_strategies()` has been called +And a config that selects `c1_vio.strategy="klt_ransac"`, `c2_vpr.strategy="net_vlad"`, `c3_matcher.strategy="disk_lightglue"`, `c4_pose.strategy="opencv_gtsam"`, `c5_state.strategy="gtsam_isam2"` (i.e. defaults) +When `compose_root(config)` runs (with required env populated) +Then it returns a `RuntimeRoot` whose `components` dict contains all 7 registered slots; no `StrategyNotLinkedError` is raised. + +**AC-3: Idempotent registration** +Given `register_airborne_strategies()` has been called once +When it is called a second time in the same process +Then no exception is raised; the registry retains the same 14+ entries (call-2 is a no-op due to equal `_Registration` records). + +**AC-4: Unknown strategy in config still raises with useful message** +Given `register_airborne_strategies()` has been called +And a config selects `c2_vpr.strategy="not_a_real_strategy"` +When `compose_root(config)` runs +Then `StrategyNotLinkedError` is raised with `strategy_name="not_a_real_strategy"`, `component_slug="c2_vpr"`, `available_strategies` including `"net_vlad"` etc., and `reason="not linked"`. + +**AC-5: Tier isolation prevents airborne registrations from leaking into compose_operator** +Given `register_airborne_strategies()` has been called (no operator registrations) +When `compose_operator(config)` runs against the same config +Then it raises `StrategyNotLinkedError` for each airborne-tier registration with `reason` mentioning the tier mismatch; no airborne strategy is constructed by the operator binary path. + +## Non-Functional Requirements + +**Performance** +- `register_airborne_strategies()` cost ≤ 50 ms on cold import (it's effectively 14 dict inserts + their dependency-resolution). + +**Reliability** +- No raw `RuntimeError` from the registry path should reach the operator — every failure mode passes through `StrategyNotLinkedError` with the contextual fields populated (already true of the existing surface). + +## Constraints + +- The wrapper factories MUST use the existing per-component factories. NEVER duplicate the BUILD_* flag gating logic inside the bootstrap — `vio_factory.build_vio_strategy` already does that for c1_vio, and similarly for each component. +- AZ-507 cross-component import rule: `runtime_root/airborne_bootstrap.py` is the composition root, so it MAY import from any component's Public API. NEVER reach into a component's internal modules; always go through the per-component factory. +- The `depends_on` declarations MUST be consistent with the per-component factory signatures. Document any inferred ordering in the wrapper factory's docstring. + +## Risks & Mitigation + +**Risk 1: Per-component factory signatures don't match `(config, constructed)`** +- *Risk*: `build_vio_strategy(config, *, fdr_client)` takes `fdr_client` as a kwarg, not from a `constructed` dict. Adapting requires the wrapper to read `constructed["c13_fdr"]` and pass it as `fdr_client=...`. But `c13_fdr` is constructed by the takeoff path (`take_off()`), NOT by `compose_root`'s registry path. So the wrapper's `constructed` may not contain `c13_fdr` at call time. +- *Mitigation*: For c1_vio specifically, the existing `take_off()` flow passes `fdr_client` separately via `other_components_factory(config, writer, fc_adapter)`. The bootstrap's wrapper for c1_vio should match this — it expects `constructed` to contain `c13_fdr`, raises a clear error if not, and the airborne entrypoint orchestrates `take_off()` to populate `constructed["c13_fdr"]` before calling `compose_root`. Document the call-order invariant in `airborne_bootstrap.py`. + +**Risk 2: Compose-root construction order doesn't match the live takeoff path** +- *Risk*: `_topo_order` runs Kahn's algorithm over the `depends_on` graph; the production `take_off()` runs a specific ordered sequence (writer → flight header → fc_adapter → other components). Disagreement between these two orderings can produce subtle bugs. +- *Mitigation*: For now, the airborne bootstrap registers ONLY the 7 strategy-selecting component slots. The `take_off()` / `_replay_branch` flows continue to own c13_fdr / c8_fc_adapter / c6_tile_cache / c7_inference / replay components via their existing direct factories. The `pre_constructed` mechanism lets the registry-driven `_compose` see them already-built. Document this explicitly in the bootstrap module docstring. + +## Notes + +- This task does NOT validate end-to-end on the airborne binary because that requires a real Jetson + nav-camera + FC. It validates that `compose_root()` returns a `RuntimeRoot` without raising — the unit-test gate. End-to-end binary validation lives in the Tier-2 Jetson harness (AZ-444). +- After this task lands, the cycle-1 completeness gate report at `_docs/03_implementation/implementation_completeness_cycle1_report.md` should be re-read: the `FAIL` classification for AZ-332 + AZ-333 is re-classified to `BLOCKED on Tier-2 prerequisites` per AZ-592 / AZ-593. The actual production blocker (this task) is being remediated here. +- The user's PBI complexity rule caps PBIs at 5pt. This task is at the 5pt boundary because all 7 slots use the same wrapper pattern (so the slot count doesn't multiply complexity). If any slot's wrapper needs more than a few-line factory adapter, that slot's wrapper should split into its own PBI (`AZ-591__bootstrap`). diff --git a/_docs/03_implementation/implementation_completeness_cycle1_report.md b/_docs/03_implementation/implementation_completeness_cycle1_report.md index dd7c45e..d92de7d 100644 --- a/_docs/03_implementation/implementation_completeness_cycle1_report.md +++ b/_docs/03_implementation/implementation_completeness_cycle1_report.md @@ -12,7 +12,65 @@ because they don't promise new runtime behavior). ## Verdict -**FAIL — Step 7 must not advance.** +**Revised 2026-05-16 (post-mortem after AZ-589/AZ-590 investigation)**: +The original verdict below classified AZ-332 + AZ-333 as `FAIL` and +created remediation tasks AZ-589 + AZ-590.
