# Hygiene — Consolidate c1_vio strategy facade orchestration spine
|
||||
|
||||
**Task**: AZ-528_hygiene_c1_vio_facade_spine_consolidation
|
||||
**Name**: c1_vio strategy facade orchestration-spine helper consolidation
|
||||
**Description**: Replace the 3-way byte-equivalent orchestration-spine duplication across the c1_vio `VioStrategy` modules (`okvis2.py`, `vins_mono.py`, `klt_ransac.py`) with a single c1-internal helper module at `src/gps_denied_onboard/components/c1_vio/_facade_spine.py`. Closes cumulative review batches 52-54 Finding F1 (Medium / Maintainability).
|
||||
**Complexity**: 3 points
|
||||
**Dependencies**: AZ-334 (the trigger that escalated the duplication from 2-way to 3-way; all 3 callers now exist). AZ-332 + AZ-333 are already in `done/`.
|
||||
**Component**: c1_vio (epic AZ-254 / E-C1)
|
||||
**Tracker**: AZ-528
|
||||
**Epic**: AZ-254 (E-C1)
|
||||
|
||||
### Document Dependencies
|
||||
|
||||
- `_docs/03_implementation/cumulative_review_batches_52-54_cycle1_report.md` § F1 — the finding being closed.
|
||||
- `_docs/02_document/components/01_c1_vio/description.md` — the c1_vio component description (helper goes inside the c1_vio boundary).
|
||||
- `_docs/02_tasks/done/AZ-332_c1_okvis2_strategy.md`, `AZ-333_c1_vins_mono_strategy.md`, `AZ-334_c1_klt_ransac_strategy.md` — the three task-specs whose existing AC tests must continue to pass unmodified after the consolidation.
|
||||
|
||||
## Problem
|
||||
|
||||
Three c1_vio `VioStrategy` modules each duplicate the same orchestration-spine helpers:
|
||||
|
||||
**Module-level free functions (byte-identical across all 3)**:
|
||||
|
||||
| Function | File | Notes |
|
||||
|----------|------|-------|
|
||||
| `_now_iso() -> str` | `okvis2.py`, `vins_mono.py`, `klt_ransac.py` | ISO-8601 UTC timestamp for FDR `ts` |
|
||||
| `_bias_norm(bias: ImuBias) -> float` | `okvis2.py`, `vins_mono.py`, `klt_ransac.py` | L2 norm of `(accel ‖ gyro)` 6-vector |
|
||||
| `_se3_from_4x4(matrix) -> gtsam.Pose3` | `okvis2.py`, `vins_mono.py`, `klt_ransac.py` | Lazy gtsam import + np-array coerce |
|
||||
| `_frame_ts_ns(frame: NavCameraFrame) -> int` | `okvis2.py`, `vins_mono.py` | UTC-epoch ns from `frame.timestamp` (KLT/RANSAC uses inline access) |
|
||||
| `_frame_image(frame: NavCameraFrame) -> np.ndarray` | `okvis2.py`, `vins_mono.py` | Contiguous uint8 ndarray + 2D/3D shape check (KLT/RANSAC owns inline grayscale conversion) |
|
||||
|
||||
**Instance methods (byte-identical modulo strategy-local config-knob references + module-level constants)**:
|
||||
|
||||
| Method | Files | Differences |
|
||||
|--------|-------|-------------|
|
||||
| `_classify_state(self, fq) -> VioState` | all 3 | Threshold attribute reference: `self._okvis2_cfg.degraded_feature_threshold` vs `self._cfg.min_features_for_pose` |
|
||||
| `_tick_lost(self, frame_id)` | all 3 | Byte-identical — increments `_consecutive_lost`, escalates to LOST at `_lost_frame_threshold` |
|
||||
| `_emit_transition(self, new_state, frame_id)` | all 3 | Differs only in module-level `_PRODUCER_ID` + `_STRATEGY_LABEL` constants captured at emit time |
|
||||
|
||||
The geometry-specific pipeline (OKVIS2 cascade init + native binding driver, VINS-Mono loosely-coupled estimator driver, KLT/RANSAC seed/track/recoverPose ladder) is unique to each strategy and stays inside each strategy module — this PBI does not touch the geometry pipelines.
|
||||
|
||||
The per-batch reviews for B53 + B54 explicitly deferred consolidation to the next cumulative review (batches 52-54). That cumulative review formally raised the finding from Low to Medium and opened this ticket.
|
||||
|
||||
## Outcome
|
||||
|
||||
- A new c1-internal module `src/gps_denied_onboard/components/c1_vio/_facade_spine.py` exposes:
|
||||
- Free functions: `now_iso()`, `bias_norm(bias)`, `se3_from_4x4(matrix)`, `frame_ts_ns(frame)`, `frame_image(frame, *, producer_id)`.
|
||||
- A `FacadeSpine` mixin class providing `_classify_state(self, fq) -> VioState`, `_tick_lost(self, frame_id) -> None`, `_emit_transition(self, new_state, frame_id) -> None`. The mixin reads strategy-specific values via per-instance attributes that each concrete strategy must set: `_feature_threshold: int`, `_warm_start_max_frames: int`, `_lost_frame_threshold: int`, `_producer_id: str`, `_strategy_label: str`, plus the existing `_reported_state`, `_frames_since_warmup`, `_consecutive_lost`, `_last_emitted_state`, `_latest_bias`, `_fdr` attributes.
|
||||
- The three c1_vio strategy modules import the helpers + inherit from the mixin. The duplicated bodies are deleted. The deferred-consolidation comments referencing this PBI are also deleted.
|
||||
- A new unit test `tests/unit/c1_vio/test_az528_facade_spine.py` covers AC-1..AC-7 below.
|
||||
- The existing AZ-332 / AZ-333 / AZ-334 AC tests pass unmodified.
|
||||
|
||||
## Scope
|
||||
|
||||
### Included
|
||||
|
||||
- Add `src/gps_denied_onboard/components/c1_vio/_facade_spine.py` with the listed free functions + `FacadeSpine` mixin. Import surface: only L1/L2 substrate (`_types.nav`, `components.c1_vio.errors`, `_types.fdr_record`, stdlib datetime + math + numpy).
|
||||
- Migrate the three c1_vio strategy modules to import the free functions and inherit from `FacadeSpine`. Delete the duplicated bodies + any in-line `post-AZ-334 hygiene` / `Batch 53 review F1` / `Batch 54 review F1` deferred-consolidation comments.
|
||||
- Add `tests/unit/c1_vio/test_az528_facade_spine.py` with AC-1..AC-7 (3 free-function tests + 3 mixin-behaviour tests + 1 regression-guard test).
|
||||
- Re-run the existing `tests/unit/c1_vio/test_okvis2_strategy.py`, `test_vins_mono_strategy.py`, `test_klt_ransac_strategy.py` AC sub-tests unmodified to verify the consolidation preserves behaviour at every call site.
|
||||
|
||||
### Excluded
|
||||
|
||||
- Sharing the spine across other components (c2, c3, c4, c5). Each component owns its own FDR record kind + state machine; sharing across components would entangle the component boundaries that AZ-507 carved cleanly.
|
||||
- Refactoring the strategy-specific geometry pipelines (OKVIS2 cascade init, VINS-Mono estimator driver, KLT/RANSAC pose-recovery ladder). Those are correctly per-strategy.
|
||||
- Changing the `vio.health` FDR record schema, the `VioState` enum values, or the `CURRENT_SCHEMA_VERSION` constant.
|
||||
- Refactoring the test fakes in `tests/unit/c1_vio/conftest.py` (`FakeOkvis2Backend` / `FakeVinsMonoBackend`) or the `_patch_pose_recovery` helper in `test_klt_ransac_strategy.py`. These are F2 from cumulative review batches 52-54; they sit at a different abstraction layer and will ride a later hygiene pass.
|
||||
- Hoisting the spine to `src/gps_denied_onboard/helpers/`. Strategy state machines + FDR record producers are c1-internal concerns by component-architecture decision.
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
**AC-1: Helper module exists at the canonical path with the expected surface**
|
||||
Given a fresh checkout
|
||||
When `from gps_denied_onboard.components.c1_vio._facade_spine import now_iso, bias_norm, se3_from_4x4, frame_ts_ns, frame_image, FacadeSpine` is run
|
||||
Then all imports succeed; `FacadeSpine` is a class; `now_iso`, `bias_norm`, `se3_from_4x4`, `frame_ts_ns`, `frame_image` are callables; `FacadeSpine` has methods `_classify_state`, `_tick_lost`, `_emit_transition`
|
||||
|
||||
**AC-2: `now_iso()` returns ISO-8601 UTC**
|
||||
Given the helper imported
|
||||
When `now_iso()` is called
|
||||
Then the return value is a string that parses as an aware UTC `datetime` via `datetime.fromisoformat(...)` and the offset is `+00:00` (matching the existing OKVIS2 / VINS-Mono / KLT-RANSAC behaviour — NOT the `Z`-suffix variant; that is `iso_ts_from_clock` in AZ-526)
|
||||
|
||||
**AC-3: `bias_norm(bias)` matches the L2 formula**
|
||||
Given an `ImuBias(accel_bias=(1.0, 2.0, 2.0), gyro_bias=(0.0, 0.0, 0.0))`
|
||||
When `bias_norm(bias)` is called
|
||||
Then the result equals `3.0` (sqrt(1+4+4))
|
||||
|
||||
**AC-4: `se3_from_4x4(matrix)` builds a `gtsam.Pose3`**
|
||||
Given a 4×4 identity matrix
|
||||
When `se3_from_4x4(np.eye(4))` is called
|
||||
Then the returned object is a `gtsam.Pose3` whose translation is `(0, 0, 0)` and whose rotation is the identity
|
||||
|
||||
**AC-5: `FacadeSpine._classify_state` mirrors the existing logic across all three strategies**
|
||||
Given a `FacadeSpine` subclass instance with `_reported_state=INIT`, `_frames_since_warmup=0`, `_warm_start_max_frames=5`, `_feature_threshold=50`
|
||||
When `_classify_state(FeatureQuality(tracked=80))` is called
|
||||
Then the return is `VioState.INIT`; after `_frames_since_warmup=5`, the same call returns `VioState.TRACKING`; with `tracked=10`, it returns `VioState.DEGRADED`
|
||||
|
||||
**AC-6: `FacadeSpine._tick_lost` transitions correctly**
|
||||
Given `_reported_state=TRACKING`, `_consecutive_lost=0`, `_lost_frame_threshold=3`
|
||||
When `_tick_lost("frame_42")` is called once
|
||||
Then `_reported_state == VioState.DEGRADED`; calling 2 more times escalates `_reported_state == VioState.LOST`
|
||||
|
||||
**AC-7: `FacadeSpine._emit_transition` emits exactly one FDR record per state change**
|
||||
Given `_last_emitted_state=TRACKING`, a fake `FdrClient`
|
||||
When `_emit_transition(VioState.TRACKING, "frame_42")` is called (no state change)
|
||||
Then no record is enqueued
|
||||
When `_emit_transition(VioState.DEGRADED, "frame_42")` is called (state change)
|
||||
Then exactly one FDR record is enqueued with `kind="vio.health"`, the payload contains `{state, consecutive_lost, bias_norm, strategy_label, frame_id}`, and `_last_emitted_state == VioState.DEGRADED`
|
||||
|
||||
**AC-8: No stray duplicated definitions remain in the three strategy modules**
|
||||
Given `grep -rn "^def _now_iso\|^def _bias_norm\|^def _se3_from_4x4\|^def _frame_ts_ns\|^def _frame_image" src/gps_denied_onboard/components/c1_vio/` after the task lands
|
||||
When the search runs
|
||||
Then matches appear only inside `_facade_spine.py`; zero matches in `okvis2.py`, `vins_mono.py`, `klt_ransac.py`
|
||||
|
||||
**AC-9: All AZ-332 / AZ-333 / AZ-334 existing AC tests pass unmodified**
|
||||
Given the existing `tests/unit/c1_vio/test_okvis2_strategy.py`, `test_vins_mono_strategy.py`, `test_klt_ransac_strategy.py`
|
||||
When the suites run after this task
|
||||
Then every previously-passing AC sub-test still passes; no test file outside the new `test_az528_facade_spine.py` is modified
|
||||
|
||||
**AC-10: AZ-270 layer lint still passes**
|
||||
Given the helper lives inside the c1_vio component (Layer 3) and only imports from L1 substrate
|
||||
When `tests/unit/test_az270_compose_root.py::test_ac6_only_compose_root_imports_concrete_strategies` runs
|
||||
Then the test passes (helper is c1-internal, underscore-prefixed, not in `c1_vio/__init__.py`'s Public API surface)
|
||||
|
||||
## Constraints
|
||||
|
||||
- The helper module is c1-internal (`_facade_spine.py` underscore prefix). No other component may import it.
|
||||
- Strategy-specific values (`_feature_threshold`, `_producer_id`, `_strategy_label`, etc.) enter the mixin through `self` attributes set by each concrete strategy's `__init__` — NOT through constructor parameters on the mixin. Keeps the mixin shape stable.
|
||||
- The free functions are stateless and pure. They MUST NOT capture module-level state from any strategy module.
|
||||
- Error envelope preserved: `_frame_image` continues to raise `VioFatalError` on bad shape; no new error types introduced.
|
||||
- `_now_iso()` keeps the existing `+00:00` offset format (not `Z`) to maintain byte-equivalence with the current OKVIS2 / VINS-Mono / KLT-RANSAC behaviour. The canonical `Z`-suffix helper is `iso_ts_from_clock` in `helpers/iso_timestamps.py` (AZ-526) which serves a different purpose (FDR record timestamps from an injected `Clock`).
|
||||
- Test additions go into a new `test_az528_facade_spine.py`; AZ-332 / AZ-333 / AZ-334 test files are NOT touched.
|
||||
- The c1_vio module-level `_PRODUCER_ID` and `_STRATEGY_LABEL` Final constants remain in each strategy module (they parametrise the mixin via the `self._producer_id` / `self._strategy_label` attributes the constructor sets). Hoisting them to `_facade_spine.py` would lose per-strategy identity.
|
||||
|
||||
## Risks & Mitigation
|
||||
|
||||
**Risk 1: The mixin's attribute dependencies (`_feature_threshold`, `_warm_start_max_frames`, etc.) are not declared statically — a strategy forgetting to set one breaks the mixin at runtime, not at type-check time.**
|
||||
- *Mitigation*: Document the required attributes in the `FacadeSpine` class docstring + introduce a `_facade_spine_attrs` property class-level check that runs at `__init_subclass__` time (or a `_validate_spine_attrs()` instance helper called from each concrete `__init__`). Add a unit test that explicitly verifies the three concrete strategies have all required attributes set after construction.
|
||||
- *Alternative*: a stricter Protocol-typed parameter object passed to `_classify_state` / `_emit_transition`. Rejected — it would force every call site to construct a parameter object, which is more boilerplate than the bug it prevents.
|
||||
|
||||
**Risk 2: A 3-way refactor accidentally changes the state-machine semantics for one of the strategies**
|
||||
- *Mitigation*: AC-9 (all 3 existing AC test suites pass unmodified) is the safety net — if any strategy regresses, its AC tests will fail. Plus the focused AC-5..AC-7 tests in the new file directly exercise the mixin logic in isolation.
|
||||
|
||||
**Risk 3: A future c1_vio strategy author forgets the mixin exists and adds a 4th local copy**
|
||||
- *Mitigation*: Add an AST-walk regression guard inside `test_az528_facade_spine.py` (modeled on the AZ-508 / AZ-526 / AZ-527 pattern) that asserts zero module-level `_now_iso` / `_bias_norm` / `_se3_from_4x4` / `_frame_ts_ns` / `_frame_image` definitions in any of the 3 strategy modules.
|
||||
|
||||
**Risk 4: Inheritance from a mixin couples the three strategies in a way that constrains future divergence**
|
||||
- *Risk*: A future strategy might need a different state-machine — e.g., a smoother-loop strategy with an extra "INITIALIZING" state.
|
||||
- *Mitigation*: The mixin is opt-in (free function `_emit_transition` is also exposed for strategies that want the FDR-record format but not the state machine). A future divergent strategy can either subclass `FacadeSpine` and override the relevant methods or skip the mixin entirely and use only the free functions.
|
||||
|
||||
## Runtime Completeness
|
||||
|
||||
- **Named capability**: a c1-internal helper module `_facade_spine.py` exposing 5 free functions (`now_iso`, `bias_norm`, `se3_from_4x4`, `frame_ts_ns`, `frame_image`) + 1 mixin class (`FacadeSpine`) providing `_classify_state` / `_tick_lost` / `_emit_transition`.
|
||||
- **Production code that must exist**: real implementations in `_facade_spine.py`; real imports + inheritance in each of the 3 strategy modules (`okvis2.py`, `vins_mono.py`, `klt_ransac.py`); existing module-level `_PRODUCER_ID` / `_STRATEGY_LABEL` / `_lost_frame_threshold` / `_warm_start_max_frames` / `_feature_threshold` constants preserved with appropriate `self.*` attribute assignments in each strategy's `__init__`.
|
||||
- **Allowed external stubs**: none for production code. The unit test uses a minimal `FacadeSpine` subclass (test-only) + a fake `FdrClient` matching the existing AZ-273 ringbuf shape.
|
||||
- **Unacceptable substitutes**: keeping one or more local definitions "for parity"; raising a different exception type; hoisting the helper to `helpers/`; changing the existing FDR record payload shape; bundling the test-fake consolidation (F2) into this PBI.

research binary only. Mirrors the AZ-332 OKVIS2 facade pattern
|

deliberately so the AZ-331 factory can treat both strategies as

||||
drop-in substitutable. Native binding is a pybind11 skeleton compiled
|
||||
behind `BUILD_VINS_MONO=ON` (default OFF for airborne /
|
||||
operator-tooling / replay-cli); estimator wiring is the Tier-2
|
||||
follow-up.

### Added (4)
|

- `src/gps_denied_onboard/components/c1_vio/vins_mono.py` — Python
|

facade, 533 lines.
|

- `src/gps_denied_onboard/components/c1_vio/_native/vins_mono_binding.cpp`
|
||||
— pybind11 binding skeleton, ~275 lines.
|
||||
- `tests/unit/c1_vio/test_vins_mono_strategy.py` — AC-1..AC-10 +
|

tier2 perf/honesty tests, 518 lines, 17 tests (15 pass, 2 skip).
|

- `_docs/03_implementation/reviews/batch_53_review.md` — code review

report.
|

|

### Modified (4)
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/__init__.py` — export
|
||||
`VinsMonoConfig`.
|
||||
- `src/gps_denied_onboard/components/c1_vio/config.py` — add
|
||||
`VinsMonoConfig` dataclass + `vins_mono` field on `C1VioConfig`;
|
||||
`__all__` updated; `KNOWN_STRATEGIES` already had `vins_mono`.
|
||||
- `cpp/vins_mono/CMakeLists.txt` — replaced AZ-263 placeholder with
|
||||
full pybind11 + linker wiring; gated by `BUILD_VINS_MONO`; ROS-strip
|
||||
flag forced OFF (Risk-1); links Eigen from
|
||||
`cpp/_third_party/eigen/` shared with OKVIS2 (Risk-2).
|
||||
- `tests/unit/c1_vio/conftest.py` — extend with `FakeVinsMonoBackend`
|
||||
+ 3 fake exception types + `fake_vins_mono_binding` fixture.
|
||||
- `tests/unit/c1_vio/test_protocol_conformance.py` — drop `vins_mono`
|
||||
from `_STRATEGIES_WITHOUT_PY_MODULE` so the existing parametrised
|
||||
factory test routes through the new strategy correctly (the
|
||||
"module missing" branch is now strictly `klt_ransac`-only until
|
||||
AZ-334 lands).
|
||||
|
||||
## AC coverage (AC-1..AC-10 + NFR-perf-document)
|
||||
|
||||
All 10 ACs mapped to passing tests (see `batch_53_review.md` Phase 2
|
||||
table). AC-9 + NFR-perf are tier2-tagged per the carry-over plan;
|
||||
they skip on macOS dev + GitHub Actions Linux runner with
|
||||
`Tier-2-only test; set GPS_DENIED_TIER=2 to run`.
|
||||
|
||||
## Test results
|
||||
|
||||
### Focused suite — `tests/unit/c1_vio/`
|
||||
|
||||
```
|
||||
72 passed, 4 skipped in 1.14s
|
||||
```
|
||||
|
||||
The 4 skips are the 2 OKVIS2 tier2 tests + the 2 new VINS-Mono tier2
|
||||
tests (`test_ac9_*` and `test_nfr_perf_*`).
|
||||
|
||||
### Adjacent regression — config / compose-root / inference shim
|
||||
|
||||
```
|
||||
22 passed in 2.87s
|
||||
```
|
||||
|
||||
(`test_az269_config_loader.py`, `test_az270_compose_root.py`,
|
||||
`test_az507_inference_errors_shim.py` — all green; the new
|
||||
`VinsMonoConfig` registration did not break the schema-loader or
|
||||
compose-root layered-import guards.)
|
||||
|
||||
### Full suite
|
||||
|
||||
```
|
||||
1 failed, 1788 passed, 82 skipped in 79.15s
|
||||
```
|
||||
|
||||
The single failure is a pre-existing environment-dependent perf flake:
|
||||
|
||||
- `tests/unit/c12_operator_orchestrator/test_cli_console_script.py::test_cold_start_under_500ms_p99`
|
||||
— measures CLI cold-start wall-clock; reports `worst-after-trim
|
||||
997.4 ms` vs the `≤ 500 ms` NFR target. macOS dev runner cannot
|
||||
hit this on a cold spawn; the test is environment-bound to Linux
|
||||
CI hardware. No touchpoint to c1_vio. Reported to the user.
|
||||
|
||||
## Architectural decisions
|
||||
|
||||
- **Mirroring OKVIS2 1:1**: the constructor / state machine / except
|
||||
ladder in `vins_mono.py` is a deliberate copy of `okvis2.py`. The
|
||||
AZ-331 factory + IT-12 harness require shape-compatibility; doing
|
||||
the consolidation now (before AZ-334's KltRansac shape is visible)
|
||||
would over-fit. Tracked as Low-severity finding F1 in the review;
|
||||
scheduled for the post-AZ-334 hygiene PBI (precedent: AZ-340 →
|
||||
AZ-527 for c2_vpr).
|
||||
- **Test fake mirroring**: same logic for `FakeVinsMonoBackend` vs
|
||||
`FakeOkvis2Backend`. The shared `ScriptedOutput` dataclass and
|
||||
`_make_default_payload` helper ARE reused (the productive cut);
|
||||
the backend class duplication is the deferred-consolidation slice.
|
||||
- **CMakeLists ROS-strip + Eigen pin**: explicit Risk-1 mitigation
|
||||
(`VINS_MONO_USE_ROS=OFF` forced), Risk-2 mitigation (Eigen pin
|
||||
from the shared `cpp/_third_party/eigen/`), Risk-3 mitigation (the
|
||||
binding never builds when `BUILD_VINS_MONO=OFF`, so deployment
|
||||
binaries stay clean).
|
||||
- **Skeleton binding throws on first frame**: matches OKVIS2 — a
|
||||
research binary that loads the `.so` before tier-2 wires the real
|
||||
`vins_estimator::Estimator` cannot silently emit misleading poses
|
||||
(`VinsMonoFatalException` from `_drive_estimator`).
|
||||
- **NFR-perf is recorded, not bounded**: per task spec, VINS-Mono is
|
||||
exempt from C1-PT-01's 80 ms p95. The tier2 perf test asserts only
|
||||
that `process_frame` completes 200× without deadlock and that p95
|
||||
is below a loose 5-second sanity ceiling. The Step 9 / E-BBT
|
||||
comparative-study report consumes the actual p50/p95 number.
|
||||
|
||||
## Out of scope / deferred
|
||||
|
||||
- Real `vins_estimator::Estimator` wiring inside the binding — Tier-2
|
||||
follow-up; not required for the AZ-333 facade ACs.
|
||||
- KltRansac strategy (AZ-334) — separate batch.
|
||||
- Warm-start hint persistence (AZ-335) — separate batch, depends on
|
||||
AZ-333 + AZ-334.
|
||||
- Strategy-facade consolidation hygiene PBI — informally tracked,
|
||||
formal PBI to be raised by the next cumulative review (batches
|
||||
52-54) once all three c1_vio strategies are landed.

# Batch 54 — Cycle 1 Report
|
||||
|
||||
**Date**: 2026-05-14
|
||||
**Tasks**: AZ-334 (C1 KLT/RANSAC Strategy)
|
||||
**Verdict**: COMPLETE — PASS_WITH_WARNINGS
|
||||
|
||||
## Summary
|
||||
|
||||
Implemented `KltRansacStrategy`, the ADR-002 engine-rule mandatory
|
||||
simple-baseline VIO for C1. Pure-Python facade over OpenCV's
|
||||
`cv2.goodFeaturesToTrack` / `cv2.calcOpticalFlowPyrLK` /
|
||||
`cv2.findEssentialMat` / `cv2.recoverPose` pipeline — no C++/pybind11
|
||||
binding by design so a Tier-0 workstation can run the strategy with
|
||||
`pip install opencv-python` and the AZ-331 factory's
|
||||
`BUILD_KLT_RANSAC=ON` gate. Mirrors the AZ-332 OKVIS2 + AZ-333
|
||||
VINS-Mono facade pattern on the orchestration spine so the AZ-331
|
||||
factory + IT-12 comparative harness treat all three strategies as
|
||||
drop-in substitutable.
|
||||
|

## Files added / modified
|

|
||||
### Added (3)
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/klt_ransac.py` —
|
||||
Python facade, ~770 lines.
|
||||
- `tests/unit/c1_vio/test_klt_ransac_strategy.py` — AC-1..AC-11 +
|
||||
NFR-perf + KltRansacConfig validation tests, ~990 lines, 25 tests
|
||||
(23 pass + 2 tier-2 skipped on dev/CI runners).
|
||||
- `_docs/03_implementation/reviews/batch_54_review.md` — code review
|
||||
report.
|
||||
|
||||
### Modified (4)
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/config.py` — add
|
||||
`KltRansacConfig` dataclass + `klt_ransac` field on `C1VioConfig`;
|
||||
`__all__` updated. (Pre-existing `KNOWN_STRATEGIES` already had
|
||||
`klt_ransac` from AZ-331.)
|
||||
- `src/gps_denied_onboard/components/c1_vio/__init__.py` — export
|
||||
`KltRansacConfig`.
|
||||
- `cpp/klt_ransac/CMakeLists.txt` — replace AZ-263 placeholder with
|
||||
a deliberate "pure-Python; no native target" STATUS message so
|
||||
the build graph stays symmetric with `cpp/okvis2/` and
|
||||
`cpp/vins_mono/` while the `BUILD_KLT_RANSAC=ON` flag only gates
|
||||
the Python module import at the AZ-331 composition-root factory.
|
||||
- `tests/unit/c1_vio/test_protocol_conformance.py` — introduce the
|
||||
`_STRATEGIES_WITHOUT_NATIVE_BINDING` category and route
|
||||
`klt_ransac` through it inside
|
||||
`test_ac5_build_vio_strategy_flag_on_but_module_missing` so the
|
||||
parametrised factory test correctly handles the pure-Python
|
||||
shape (no native binding to fail on; the construction should
|
||||
succeed and return a `VioStrategy` instance instead).
|
||||
|
||||
## AC coverage (AC-1..AC-11 + NFR-perf)
|
||||
|
||||
All 11 ACs + NFR-perf mapped to passing tests (see
|
||||
`batch_54_review.md` Phase 2 table). AC-9 + NFR-perf are
|
||||
tier-2-tagged per the task spec; they skip on macOS dev + GitHub
|
||||
Actions Linux runner with `Tier-2-only test; set GPS_DENIED_TIER=2
|
||||
to run`. AC-3 / AC-6 / AC-9 / AC-10 / AC-11 / NFR-perf monkeypatch
|
||||
`cv2.findEssentialMat` + `cv2.recoverPose` +
|
||||
`RansacFilter.filter_correspondences` to deterministic values so
|
||||
the unit suite exercises the FACADE's state machine without
|
||||
depending on real OpenCV geometry on synthetic correspondences;
|
||||
real-geometry validation lives in C1-IT-12 (Jetson Tier-2 fixture).
|
||||
|
||||
## Test results
|
||||
|
||||
### Focused suite — `tests/unit/c1_vio/`
|
||||
|
||||
```
|
||||
95 passed, 6 skipped in 1.67s
|
||||
```
|
||||
|
||||
The 6 skips are the 2 OKVIS2 tier-2 tests + the 2 VINS-Mono tier-2
|
||||
tests + the 2 new KLT/RANSAC tier-2 tests (`test_ac9_*` and
|
||||
`test_nfr_perf_*`).
|
||||
|
||||
### Adjacent regression — config / compose-root
|
||||
|
||||
```
|
||||
17 passed in 1.96s
|
||||
```
|
||||
|
||||
(`test_az269_config_loader.py`, `test_az270_compose_root.py` — all
|
||||
green; the new `KltRansacConfig` registration did not break the
|
||||
schema-loader or compose-root layered-import guards.)
|
||||
|
||||
### Tier-2 verification
|
||||
|
||||
```
|
||||
GPS_DENIED_TIER=2 pytest tests/unit/c1_vio/test_klt_ransac_strategy.py
|
||||
→ 25 passed in 0.43s
|
||||
```
|
||||
|
||||
All 25 tests pass under the tier-2 gate (including AC-9 honest-
|
||||
covariance monotonicity over 48 synthetic frames + NFR-perf p95
|
||||
record).
|
||||
|
||||
### Full suite
|
||||
|
||||
Deferred per the implement skill's Test-Run Cadence — the full
|
||||
unit-suite gate runs exactly once at Step 16 (end of implementation
|
||||
phase), not per-batch. Focused tests + cumulative review (every K
|
||||
batches) catch cross-batch regressions before then.
|
||||
|
||||
## Architectural decisions
|
||||
|
||||
- **No native binding by design**: KLT/RANSAC is pure Python over
|
||||
OpenCV's Python bindings. The `cpp/klt_ransac/CMakeLists.txt`
|
||||
placeholder is preserved (with an explanatory STATUS message) for
|
||||
build-graph symmetry with `cpp/okvis2/` and `cpp/vins_mono/`; the
|
||||
`BUILD_KLT_RANSAC=ON` flag only gates the Python module import at
|
||||
the AZ-331 composition-root factory.
|
||||
- **Constructor shape matches factory**: `KltRansacStrategy(config,
|
||||
*, fdr_client, clock=None)` mirrors `Okvis2Strategy` +
|
||||
`VinsMonoStrategy` so the AZ-331 factory invokes all three via the
|
||||
same call shape. The task spec's illustrative constructor
|
||||
(with explicit injection of `CameraCalibration` / `ImuPreintegrator`
|
||||
/ `RansacFilter` / `Logger`) was deliberately not adopted because
|
||||
it would diverge from the existing factory contract; the same
|
||||
dependencies are resolved internally instead — `RansacFilter` is
|
||||
static (AZ-282 stateless helper) and `ImuPreintegrator` is
|
||||
constructed lazily on the first `process_frame` call (it needs
|
||||
the per-call `CameraCalibration` which is not available at
|
||||
construction time).
|
||||
- **Honest covariance, AC-9 compliant**: per-frame covariance =
|
||||
`np.eye(6) * (sigma_sq + inlier_penalty) / max(inlier_count - 5, 1)`
|
||||
where `sigma_sq = median_residual_px**2` and `inlier_penalty =
|
||||
threshold_px / max(inlier_count, 1)`. No client-side floor or
|
||||
smoother; the formula grows monotonically as inliers drop or
|
||||
residuals scatter. Tier-2 test walks 48 scripted-inlier frames
|
||||
through the DEGRADED window and verifies monotonicity.
|
||||
- **Camera agnostic, AC-11 enforced**: no `adti20` / `adti26`
|
||||
literals in executable source (docstring mentions are excluded
|
||||
from the CI grep via AST-aware stripping in the test). The
|
||||
per-call `CameraCalibration` argument carries intrinsics; the
|
||||
same code path produces sensible `VioOutput` for two distinct
|
||||
calibrations (different f, cx, cy).
|
||||
- **State machine mirrors OKVIS2 / VINS-Mono**: `INIT` until
|
||||
`warm_start_max_frames` is exhausted, then `TRACKING` if inlier
|
||||
count ≥ `min_features_for_pose`, else `DEGRADED`; sustained
|
||||
pose-recovery failure for `lost_frame_threshold` consecutive
|
||||
frames raises `VioFatalError` with state == `LOST`. Exactly one
|
||||
`vio.health` FDR record per transition (AC-10).
|
||||
- **Error envelope closed**: every OpenCV `cv2.error` is caught at
|
||||
each call site and rewrapped into `VioFatalError` with
|
||||
`__cause__` chaining (AC-4). `RansacFilterError` +
|
||||
`ImuPreintegrationError` are also caught and rewrapped.
|
||||
|
||||
## Out of scope / deferred
|
||||
|
||||
- Real geometry validation against Derkachi fixtures — Tier-2
|
||||
follow-up; C1-IT-12 binds KLT/RANSAC alongside OKVIS2.
|
||||
- Warm-start hint persistence (AZ-335) — separate batch.
|
||||
- Strategy-facade consolidation hygiene PBI — now formally in scope
|
||||
for the cumulative review covering batches 52-54 (next trigger).
|
||||
All three strategy shapes (OKVIS2, VINS-Mono, KLT/RANSAC) are
|
||||
now visible so the right factoring (template-method base class
|
||||
for the orchestration spine + per-strategy geometry hook) can be
|
||||
scoped without over-fitting.
|
||||
|
||||
## Honest-covariance numeric envelope (AC-9 evidence)
|
||||
|
||||
Tier-2 test walks the following inlier-count sequence through the
|
||||
DEGRADED gate (`min_features_for_pose=50`):
|
||||
|
||||
| Frame range | Inlier count | State | Cov Frobenius (approx) |
|
||||
|-------------|--------------|----------|------------------------|
|
||||
| 1 | first-frame | INIT | 24.49 (10·√6) |
|
||||
| 2..29 | 80 | TRACKING | ≈ 0.0056 |
|
||||
| 30 | 40 | DEGRADED | ≈ 0.013 |
|
||||
| 31..43 | 35..12 | DEGRADED | strictly increasing |
|
||||
| 44..49 | 10 | DEGRADED | ≈ 0.127 |
|
||||
|
||||
The Frobenius norm grows monotonically across the entire DEGRADED
|
||||
window — the AC-9 honest-covariance invariant is upheld by the
|
||||
formula's structure, not by a floor clamp.

# Batch 55 — Cycle 1 Report
|
||||
|
||||
**Date**: 2026-05-14
|
||||
**Tasks**: AZ-528 (Hygiene — c1_vio strategy facade orchestration-spine consolidation)
|
||||
**Verdict**: COMPLETE — PASS
|
||||
|
||||
## Summary
|
||||
|
||||
Consolidated the 3-way orchestration-spine duplication across the
|
||||
c1_vio `VioStrategy` modules (`okvis2.py`, `vins_mono.py`,
|
||||
`klt_ransac.py`) into a single c1-internal helper module
|
||||
`_facade_spine.py`. Closes cumulative review batches 52-54 Finding
|
||||
F1 (Medium / Maintainability). Mirrors the AZ-527 precedent for the
|
||||
c2_vpr-side `_assert_engine_output_dim` consolidation. No behaviour
|
||||
change — every existing AZ-332 / AZ-333 / AZ-334 AC test passes
|
||||
unmodified.
|
||||
|
||||
## Files added / modified
|
||||
|
||||
### Added (2)
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/_facade_spine.py` — new
|
||||
c1-internal helper, 225 lines. Exports 5 free functions (`now_iso`,
|
||||
`bias_norm`, `se3_from_4x4`, `frame_ts_ns`, `frame_image`) and the
|
||||
`FacadeSpine` mixin class (`_classify_state`, `_tick_lost`,
|
||||
`_emit_transition`).
|
||||
- `tests/unit/c1_vio/test_az528_facade_spine.py` — new test file, 19
|
||||
tests covering AC-1..AC-8 + a Risk-1 mitigation test (each
|
||||
strategy's `__init__` statically asserts that every spine-required
|
||||
attribute is assigned). All pass.
|
||||
|
||||
### Modified (3)
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/okvis2.py` — inherit from
|
||||
`FacadeSpine`; import the 5 free functions; delete the 5 local
|
||||
module-level definitions, 3 instance methods, and the unused
|
||||
`_BIAS_NORM_FLOOR` constant. Set the 3 spine-required attributes
|
||||
(`_feature_threshold`, `_producer_id`, `_strategy_label`) in
|
||||
`__init__`.
|
||||
- `src/gps_denied_onboard/components/c1_vio/vins_mono.py` — same
|
||||
pattern as `okvis2.py`.
|
||||
- `src/gps_denied_onboard/components/c1_vio/klt_ransac.py` — same
|
||||
pattern; spine threshold reads `self._cfg.min_features_for_pose`
|
||||
(the KLT-side equivalent of OKVIS2's `degraded_feature_threshold`).
|
||||
Deferred-consolidation comments referencing this PBI removed.
|
||||
|
||||
## Tests
|
||||
|
||||
- `tests/unit/c1_vio/test_az528_facade_spine.py` — 19 new tests, all
|
||||
pass.
|
||||
- `tests/unit/c1_vio/` (full focused suite) — 120 collected, 114
|
||||
pass + 6 tier-2 skipped (unchanged from pre-AZ-528 state).
|
||||
- Adjacent regression suite (`test_az270_compose_root`,
|
||||
`test_az272_fdr_record_schema`, `test_az273_fdr_client_ringbuf`,
|
||||
`test_ac1_scaffold_layout`, `tests/unit/c1_vio/`) — 237 pass + 6
|
||||
skipped.

# Batch 56 — Cycle 1 Report
|
||||
|
||||
**Date**: 2026-05-14
|
||||
**Tasks**: AZ-335 (C1 Warm-Start + F8 Reboot Recovery)
|
||||
**Verdict**: COMPLETE — PASS_WITH_WARNINGS
|
||||
|
||||
## Summary
|
||||
|
||||
Implemented the cross-strategy warm-start hint persistence layer, the
|
||||
F2 takeoff (FC EKF) and F8 reboot (disk) prime hooks, and the AC-5.3
|
||||
"no fake confidence" covariance enforcement at the runtime composition
|
||||
layer. The persistence layer is c1-internal
|
||||
(`components/c1_vio/warm_start_store.py`); the cross-strategy wiring
|
||||
(wrapper + prime hooks) lives at the composition root
|
||||
(`runtime_root/warm_start_wiring.py`) so any concrete `VioStrategy`
|
||||
gains warm-start behaviour without per-strategy edits. AC-5.3 is
|
||||
enforced via a wrapper-owned post-reset covariance inflation +
|
||||
baseline floor — not by mutating any strategy. Default ships with the
|
||||
`JsonSidecarWarmStartHintStore` (atomic JSON + SHA-256 sidecar via
|
||||
AZ-280); a future Redis-backed store can plug in via the same
|
||||
`WarmStartHintStore` Protocol without touching the wiring.
|
||||
|
||||
Closes the AZ-335 dependency chain: AZ-331 / AZ-332 / AZ-333 / AZ-334
|
||||
(strategies) + AZ-263 / AZ-269 / AZ-266 / AZ-270 (bootstrap +
|
||||
config + log + compose lint) + AZ-280 (sha256 sidecar) + AZ-272 (FDR
|
||||
schema). Runs immediately after AZ-528 (batch 55) — no other c1_vio
|
||||
work was blocked behind AZ-335.
|
||||
|
||||
## Files added / modified
|
||||
|
||||
### Added (3)
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/warm_start_store.py` — 440
|
||||
lines. Exports `HINT_FILENAME`, `HINT_SCHEMA_VERSION`,
|
||||
`LoadedWarmStartHint` dataclass, `WarmStartHintStore` Protocol,
|
||||
`WarmStartFcSource` Protocol (consumer-side cut over C8 FcAdapter
|
||||
per AZ-507), and the default `JsonSidecarWarmStartHintStore` impl.
|
||||
JSON schema v1: `version`, `calibration_id` (Risk-2 mitigation),
|
||||
`pre_reboot_covariance_norm` (AC-8 floor), `pose` block (4×4 matrix
|
||||
+ velocity + bias + ns timestamp).
|
||||
- `src/gps_denied_onboard/runtime_root/warm_start_wiring.py` — 563
|
||||
lines. Exports `WARM_START_PRODUCER_ID`, `WarmStartWiredStrategy`
|
||||
(the wrapper that adds AC-6 throttled save + AC-7 inflation + AC-8
|
||||
floor on top of any inner `VioStrategy`),
|
||||
`prime_warm_start_from_disk` (F8 hook), and
|
||||
`prime_warm_start_from_fc` (F2 hook). Single point of FDR record
|
||||
emission via `_emit_prime_fdr` and single point of INFO/WARN log
|
||||
emission via `_emit_prime_log`.
|
||||
- `tests/unit/c1_vio/test_az335_warm_start.py` — 34 unit tests
|
||||
covering all 10 ACs + 3 NFRs. Local fakes for `VioStrategy` and
|
||||
`WarmStartFcSource`; real `Sha256Sidecar` on `tmp_path` for the
|
||||
store tests so AC-1 / AC-2 / AC-10 atomicity contracts are
|
||||
exercised against the production helper.
|
||||
|
||||
### Modified (3)
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/config.py` — added
|
||||
`warm_start_store_dir` (default `/var/lib/gps_denied_onboard/warm_start/`),
|
||||
`warm_start_save_period_frames` (default 5),
|
||||
`post_reset_covariance_inflation_factor` (default 2.0). Each new
|
||||
field has a `__post_init__` validation matching the existing
|
||||
pattern.
|
||||
- `src/gps_denied_onboard/fdr_client/records.py` — registered the new
|
||||
FDR kind `vio.warm_start` in `KNOWN_PAYLOAD_KEYS` with the
|
||||
frozen schema {`source`, `strategy_label`, `bias_norm`,
|
||||
`staleness_ns`, `pre_reboot_covariance_norm`}.
|
||||
- `tests/unit/test_az272_fdr_record_schema.py` — added the per-kind
|
||||
fixture branch for `vio.warm_start` so the AC-1 round-trip suite
|
||||
stays exhaustive over `KNOWN_KIND`.
|
||||
|
||||
## Tests
|
||||
|
||||
- `tests/unit/c1_vio/test_az335_warm_start.py` — 34 new tests, all
|
||||
pass (4.01 s).
|
||||
- Adjacent regression sweep (`tests/unit/c1_vio/`,
|
||||
`tests/unit/c13_fdr/`, `tests/unit/composition_root/`,
|
||||
`test_az272_fdr_record_schema`, `test_az269_config_loader`,
|
||||
`test_az270_compose_root`, `test_az273_fdr_client_ringbuf`,
|
||||
`test_az266_logging_schema`, `test_ac1_scaffold_layout`) — 356
|
||||
pass + 6 tier-2 skipped (unchanged from pre-AZ-335 state).

## Code review
|
||||
|
||||
See `_docs/03_implementation/reviews/batch_56_review.md` — verdict
|
||||
**PASS_WITH_WARNINGS**, 1 Medium + 3 Low findings, all
|
||||
informational / documentation-tightening:
|
||||
|
||||
- F1 (Style, Low): AC-3 spec text shorthand vs source-suffixed log
|
||||
kind — recommend updating spec phrasing in cycle 2.
|
||||
- F2 (Maintainability, Medium): per-frame save uses strategy-frame
|
||||
pose as `body_T_world`; semantically defensible because the
|
||||
strategy's "internal frame" persists across F8 reload via the
|
||||
saved pose; recommend an inline 3-line comment explaining the
|
||||
design choice.
|
||||
- F3 (Spec-Gap, Low): NFR perf tests are dev-hardware smoke; full
|
||||
Tier-2 NVMe perf gate is owned by C1-PT-01 (deferred to E-BBT).
|
||||
- F4 (Architecture, Low): `runtime_root/warm_start_wiring.py`
|
||||
imports c1-internal `_facade_spine` for shared FDR conventions;
|
||||
allowed by module-layout §6, but noted for a possible future
|
||||
promotion of `bias_norm` to `helpers/imu_bias.py`.
|
||||
|
||||
## Outcomes & lessons
|
||||
|
||||
- The Protocol-cut-at-consumer pattern (defining `WarmStartFcSource`
|
||||
inside `c1_vio/warm_start_store.py` instead of importing the
|
||||
concrete C8 `FcAdapter`) is the right shape for AZ-507 compliance.
|
||||
The composition root will wire a thin adapter from C8's actual
|
||||
`FcAdapter` to this Protocol. The AZ-335 wiring tests inject a
|
||||
fake matching the surface directly — no C8 dependency in the test.
|
||||
- Wrapping (rather than per-strategy mixing) for cross-strategy
|
||||
concerns scales: AC-7 inflation + AC-8 floor + AC-6 throttled save
|
||||
all live in one 240-line wrapper class with one inner
|
||||
`VioStrategy` field. The three strategies (OKVIS2 / VINS-Mono /
|
||||
KLT-RANSAC) needed zero edits.
|
||||
- AC-7 and AC-8 stack cleanly: inflation is applied first, then if
|
||||
the inflated norm is below the AC-8 floor it is scaled up to the
|
||||
floor. Both operations preserve SPD because they're positive
|
||||
scalar multiplications. No matrix re-decomposition required.
|
||||
- The AC-NFR-no-crash policy (catch + log + return False; never
|
||||
propagate) is enforced at every prime hook seam: FC source raise,
|
||||
FC source returns None, store.save raises, inner.reset raises.
|
||||
Each path emits a distinct log `kind` so post-mortem can
|
||||
partition the failure mode.
|
||||
|
||||
## Outstanding
|
||||
|
||||
- F1 / F2 / F3 / F4 from this batch's review — non-blocking;
|
||||
recommend folding into a future hygiene PBI alongside any AZ-345+
|
||||
c3 work that touches the same `vio.warm_start` FDR namespace.
|
||||
- The composition root's `compose_*` binaries do NOT yet wire a
|
||||
`WarmStartWiredStrategy` over the `vio_factory` output. The wiring
|
||||
is in place; the actual call site (`runtime_root/runtime.py` or
|
||||
the per-binary compose script) needs to construct the
|
||||
`WarmStartWiredStrategy` + `JsonSidecarWarmStartHintStore` and
|
||||
call the F8 prime hook before the first `process_frame`. This is
|
||||
out of scope for AZ-335 (the spec only delivers the wiring
|
||||
module, not the per-binary integration); the integration belongs
|
||||
to the next-cycle compose-root task that adds the F2/F8 hook
|
||||
invocations alongside the existing strategy build.
|
||||
|
||||
## Next batch
|
||||
|
||||
AZ-345 (C3 DISK + LightGlue Primary Matcher, 5 points) is the next
|
||||
unblocked product PBI per `_dependencies_table.md`. All its
|
||||
dependencies (AZ-263, AZ-269, AZ-278, AZ-282, AZ-298, AZ-299,
|
||||
AZ-303, AZ-281, AZ-321, AZ-266, AZ-272, AZ-344) are complete.

# Cumulative Code Review — Batches 52-54 (Cycle 1)
|
||||
|
||||
**Date**: 2026-05-14
|
||||
**Range**: batches 52 (AZ-527 — c2_vpr `_assert_engine_output_dim` consolidation), 53 (AZ-333 — C1 VINS-Mono Strategy), 54 (AZ-334 — C1 KLT/RANSAC Strategy)
|
||||
**Compared against**: previous cumulative review batches 49-51
|
||||
**Verdict**: **PASS_WITH_WARNINGS**
|
||||
|
||||
## Scope
|
||||
|
||||
32 files changed across batches 52-54 (`git diff --stat f6a180e..HEAD`): 16 src/, 5 test/, 1 native binding (cpp), 2 cmake, 6 docs (3 batch reports + 3 review reports), 2 indirect (package init + deps table + state file). Cumulative review focuses on cross-batch concerns that per-batch reviews cannot catch: duplicate symbols introduced across different batches, architecture drift across the trio, contract drift between producer/consumer batches, and follow-through on prior cumulative findings.
|
||||
|
||||
The trio is the strategic centre of this window: AZ-333 + AZ-334 completed the c1_vio `VioStrategy` triplet (Okvis2 + VinsMono + KltRansac), making the orchestration-spine duplication finding (deferred since B53) actionable for the first time. AZ-527 closed the parallel c2_vpr-side finding.
|
||||
|
||||
## Carry-over closure from cumulative review 49-51
|
||||
|
||||
| Prior finding | Status | Notes |
|
||||
|---------------|--------|-------|
|
||||
| F1 (Medium) — `_assert_engine_output_dim` duplicated 7-way across c2_vpr strategies | **CLOSED by AZ-527 / Batch 52** | All 7 strategy modules (`ultra_vpr.py`, `net_vlad.py`, `mega_loc.py`, `mix_vpr.py`, `sela_vpr.py`, `eigen_places.py`, `salad.py`) now import `assert_engine_output_dim` from `c2_vpr/_engine_dim_assertion.py`. Regression guard: `tests/unit/c2_vpr/test_az527_engine_dim_assertion.py::test_ac4_no_stray_engine_dim_assertion_definitions_outside_helper` (AST walk) + `::test_ac4_seven_strategy_modules_import_the_helper` (import grep). Helper stays c2-internal (underscore-prefixed module, NOT in `c2_vpr/__init__.py`'s Public API). |
|
||||
| F2 (Low) — AC-10 spec wording drift (`ConfigurationError` vs `StrategyNotAvailableError`/`ConfigError`) across AZ-337/338/339/340 specs | **OPEN — carry forward** | Documentation-only drift in `_docs/02_tasks/done/AZ-337..AZ-340_*.md` § AC-10. No code defect. Sized at <1 point; can ride along with any future c2_vpr spec touch. Not escalated. |

|
||||
|
||||
## Finding Details
|
||||
|
||||
### F1: c1_vio strategy facade orchestration spine duplicated 3-way (Medium / Maintainability) — AZ-528 created
|
||||
|
||||
- **Locations**:
|
||||
- `src/gps_denied_onboard/components/c1_vio/okvis2.py` (AZ-332)
|
||||
- `src/gps_denied_onboard/components/c1_vio/vins_mono.py` (AZ-333, B53)
|
||||
- `src/gps_denied_onboard/components/c1_vio/klt_ransac.py` (AZ-334, B54)
|
||||
|
||||
- **Description**: The following module-level helpers are byte-identical across all three strategy modules:
|
||||
|
||||
- `_now_iso() -> str` — ISO-8601 UTC timestamp for FDR record `ts`.
|
||||
- `_bias_norm(bias: ImuBias) -> float` — L2 norm of the concatenated 6-vector `(accel ‖ gyro)`.
|
||||
- `_se3_from_4x4(matrix) -> gtsam.Pose3` — lazy gtsam import + np-array coerce.
|
||||
|
||||
The following instance methods are byte-identical modulo strategy-local config-knob references and the strategy-label / producer-ID constants:
|
||||
|
||||
- `_classify_state(self, fq) -> VioState` — INIT/TRACKING/DEGRADED gate; differs only in the threshold attribute (`self._okvis2_cfg.degraded_feature_threshold` vs `self._cfg.min_features_for_pose`).
|
||||
- `_tick_lost(self, frame_id)` — DEGRADED/LOST transition counter; byte-identical.
|
||||
- `_emit_transition(self, new_state, frame_id)` — FDR `vio.health` record emit; differs only in the module-level `_PRODUCER_ID` and `_STRATEGY_LABEL` constants captured at emit time.
|
||||
- `_frame_ts_ns(frame)` + `_frame_image(frame)` — OKVIS2 + VINS-Mono only; KLT/RANSAC uses inline numpy access (equivalent shape; remains exempt from the consolidation since its geometry pipeline owns image coercion).
|
||||
|
||||
The geometry-specific pipeline (OKVIS2 cascade init + native binding driver, VINS-Mono loosely-coupled estimator driver, KLT/RANSAC seed/track/recoverPose) IS unique to each strategy and lives in its own module. That boundary is correct — the hygiene PBI does NOT touch the geometry pipelines.
|
||||
|
||||
- **Action taken**: Hygiene PBI **AZ-528** formally opened in Jira (`Hygiene — consolidate c1_vio strategy facade orchestration spine`, 3 points, Epic AZ-254 E-C1). Scope: add `src/gps_denied_onboard/components/c1_vio/_facade_spine.py` exposing the 3 free functions + a `FacadeSpine` mixin parametrised by a strategy-local feature-threshold hook; replace the duplicated definitions in the 3 strategy modules with imports; add a focused unit test + AST-walk regression guard + import-grep regression guard; re-run existing AZ-332 / AZ-333 / AZ-334 AC tests unmodified. Link: <https://denyspopov.atlassian.net/browse/AZ-528>.
|
||||
|
||||
- **Why escalated from Low (B53 + B54 per-batch) to Medium**: at 3-way the per-edit risk of one copy drifting from the others (different error-message wording, different state-machine threshold semantics, different FDR payload field order) is non-trivial — the same logic the cumulative B46-48 review used to escalate `_iso_ts_from_clock`. Every future c1_vio strategy would add a 4th copy unless we close the pattern now. The right factoring (template-method spine + per-strategy geometry hook) is now visible because all three strategy shapes exist; doing the consolidation before AZ-334 landed would have over-fit the spine to the OKVIS2 + VINS-Mono pair.
|
||||
|
||||
- **Why Medium, not High**: the duplication is structurally bounded — three strategy files, no consumer code drifting around it. The spine is byte-identical today; there is no active drift. High would be appropriate only if one copy had already drifted from the others (it has not — the per-batch reviews verified parity at each land).
|
||||
|
||||
### F2: c1_vio test fakes / `_patch_pose_recovery` not yet shared (Low / Maintainability)
|
||||
|
||||
- **Locations**:
|
||||
- `tests/unit/c1_vio/conftest.py` (`FakeOkvis2Backend` + `FakeVinsMonoBackend`)
|
||||
- `tests/unit/c1_vio/test_klt_ransac_strategy.py` (`_patch_pose_recovery`)
|
||||
|
||||
- **Description**: `FakeOkvis2Backend` and `FakeVinsMonoBackend` are near-copies with renamed exception types and renamed scripted-output payloads. The shared `ScriptedOutput` dataclass + `_make_default_payload` helper ARE already extracted to `conftest.py` (the productive cut from B53). The KLT/RANSAC test file uses a different abstraction (`_patch_pose_recovery` monkey-patches real OpenCV bindings rather than substituting a fake backend) because KLT/RANSAC has no native binding to fake. A unified "scripted success per strategy" fixture surface is plausible but lives at a different abstraction layer than F1.
|
||||
|
||||
- **Suggestion**: defer to a later hygiene pass — explicitly NOT bundled into AZ-528. The facade-spine consolidation should land cleanly first; the test-fixture refactor can ride a future c1_vio touch (e.g. when AZ-335 / warm-start hint persistence lands). Sized at 1-2 points. Recording here so the next cumulative review sees it carried over rather than re-discovered.
|
||||
|
||||
- **Defer rationale**: Low severity, no active drift, no test instability. The two abstractions (fake backend vs monkeypatch real bindings) genuinely differ — they may not collapse into a single shape and forcing them would create the wrong base class.
|
||||
|
||||
## Phase Summary
|
||||
|
||||
### Phase 1 — Context Loading
|
||||
|
||||
- 3 task specs reviewed (AZ-527, AZ-333, AZ-334) from `_docs/02_tasks/done/`.
|
||||
- 5 doc inputs: `_docs/02_document/architecture.md`, `_docs/02_document/module-layout.md`, the 3 per-batch reviews (`batch_52_review.md` / `batch_53_review.md` / `batch_54_review.md`), and `_docs/02_document/components/01_c1_vio/description.md` + `02_c2_vpr/description.md`.
|
||||
- No `_docs/02_document/architecture_compliance_baseline.md` exists yet; the **Baseline Delta** section is omitted from this report (consistent with prior cumulative reviews).
|
||||
|
||||
### Phase 2 — Spec Compliance
|
||||
|
||||
Per-batch reviews covered AC-by-AC compliance for each task (B52: 6/6 + 1 NFR; B53: 10/10 + 1 NFR; B54: 11/11 + 1 NFR). Cross-batch checks:
|
||||
|
||||
- **AZ-333 + AZ-334 strategy-facade parity vs AZ-332 (OKVIS2)**: the two new strategies line up with OKVIS2's structural skeleton — module-level helpers (`_now_iso`, `_bias_norm`, `_se3_from_4x4`) + instance-method spine (`_classify_state`, `_tick_lost`, `_emit_transition`) + per-strategy geometry pipeline. The byte-equivalence is exactly what makes the AZ-331 factory + IT-12 comparative harness work — F1 captures it as the consolidation target, NOT as a drift defect.
|
||||
- **`_STRATEGY_TO_BUILD_FLAG` / `_STRATEGY_TO_MODULE` pre-wiring** in `runtime_root/vio_factory.py`: the 3 rows for `okvis2`, `vins_mono`, `klt_ransac` were added at AZ-331 land time and remain untouched by AZ-333 / AZ-334 — verified by reading the factory module (unchanged in this window). Strategy modules now actually exist for all 3 entries — no more silent ImportError surprises if a downstream test toggles a build flag ON.
|
||||
- **`vio.health` FDR record schema parity**: all three strategies emit FDR records with identical payload shape (`{state, consecutive_lost, bias_norm, strategy_label, frame_id}`) — verified by reading the `_emit_transition` bodies. The only difference is the `strategy_label` value; that field exists precisely to disambiguate at consumer-side.
|
||||
- **AZ-527 closure** of cumulative-49-51 F1: verified — `_assert_engine_output_dim` definitions exist in exactly 1 place (`c2_vpr/_engine_dim_assertion.py`); the 7 strategy modules import the helper.
|
||||
|
||||
No Spec-Gap findings.
|
||||
|
||||
### Phase 3 — Code Quality
|
||||
|
||||
- **SRP**: each new strategy and the new c2_vpr helper has a single clear concern. The c1_vio strategies' SRP boundary is at the geometry-pipeline level; the facade-spine duplication is a DRY concern (F1), not an SRP one.
|
||||
- **Error handling**: typed exception envelopes (`VioFatalError`, `VioInitializingError`, `RansacFilterError`, `ImuPreintegrationError`, `ConfigError`, `StrategyNotAvailableError`) used consistently across all three c1_vio strategies + the c2_vpr helper; no bare `except`; `__cause__` chaining preserved at every rewrap point.
|
||||
- **Naming**: aligned across the three c1_vio strategies — method shapes mirror line-for-line (which is the F1 target).
|
||||
- **Test quality**: B52, B53, B54 each follow the AAA pattern; behaviourally-meaningful assertions throughout; no "did not throw" placeholder tests. KLT/RANSAC's monkeypatch-based deterministic testing (F2 location) is the most novel pattern in the window — it correctly tests the facade's state machine without depending on real OpenCV geometry on synthetic correspondences; real-geometry validation is correctly deferred to C1-IT-12 (Jetson Tier-2 fixture).
|
||||
- **Test-environment-mirrors-prod gate**: still satisfied — fakes mirror the production binding interfaces (`Okvis2Backend`, `VinsMonoBackend` Protocol-shaped fakes; KLT/RANSAC monkey-patches the real `cv2` symbols).
|
||||
- **Annotation form**: `from __future__ import annotations` + bare type names — Ruff `UP037` clean across all 16 src files in the window.
|
||||
|
||||
### Phase 4 — Security Quick-Scan
|
||||
|
||||
No SQL, no `subprocess`, no `eval` / `exec`, no secrets. New code is pure-Python numerical wiring + FDR record emission + (for VINS-Mono) a pybind11 binding skeleton that is gated OFF by default (`BUILD_VINS_MONO=OFF`). Input validation present at the bindings boundary (numpy shape/dtype checks for 3×3 K, 4×4 pose, length-3 IMU vectors). n/a.
|
||||
|
||||
### Phase 5 — Performance Scan
|
||||
|
||||
- All three c1_vio strategies budget at p95 ≤ 80 ms on Tier-2 per ADR-002 (OKVIS2 + KLT/RANSAC bound by C1-PT-01; VINS-Mono exempt per task spec). Honest-covariance estimators avoid client-side floors (verified by AC-9 tier-2 tests in B53 + B54).
|
||||
- AZ-527's helper consolidation has zero hot-path impact — assertion runs at engine `create()` time (startup), not per frame.
|
||||
- No N+1, no unbounded buffers. FDR client capacity bounded by AZ-273 ringbuf at the producer side; tests cap explicitly at 256.
|
||||
|
||||
### Phase 6 — Cross-Task Consistency
|
||||
|
||||
- **Strategy-facade pattern parity across the c1_vio triplet**: confirmed — same spine, same FDR record kind (`vio.health`), same state enum (`VioState{INIT,TRACKING,DEGRADED,LOST}`), same error envelope. F1 IS the cost of this parity until AZ-528 lands.
|
||||
- **`assert_engine_output_dim` import consistency across c2_vpr**: all 7 c2_vpr strategy modules now import the helper — verified by AZ-527's import-grep regression guard (`test_ac4_seven_strategy_modules_import_the_helper`).
|
||||
- **No cross-component leakage**: c1_vio facade-spine duplication is intra-component (3 c1_vio modules); not duplicated into c2_vpr or any other component. c2_vpr `_assert_engine_output_dim` consolidation kept the helper c2-internal (underscore-prefixed module, not exported). Component boundaries preserved.
|
||||
- **FDR record schema**: no schema-level additions in this window. The 3 c1_vio strategies emit the same `vio.health` record kind; the 5 c2_vpr secondary backbones (from B50-51) continue to emit `vpr.embedding_complete` / `vpr.retrieval_complete` / `vpr.query_failed`. Verified by `tests/unit/test_az272_fdr_record_schema.py` (passes unmodified).
|
||||
- **`KltRansacConfig` schema extension**: added to `c1_vio/config.py` + exported via `c1_vio/__init__.py`; `KNOWN_STRATEGIES` already had `klt_ransac` from AZ-331. Wiring is symmetric with `Okvis2Config` + `VinsMonoConfig` — verified by `test_az269_config_loader.py` (passes).
|
||||
- **AZ-527 closure** of cumulative-49-51 F1: verified — zero `_assert_engine_output_dim` definitions remain anywhere under `src/gps_denied_onboard/components/c2_vpr/` except in `_engine_dim_assertion.py`.
|
||||
|
||||
### Phase 7 — Architecture Compliance
|
||||
|
||||
1. **Layer direction**: all changed files in this window import only from L1 substrate (`_types`, `helpers/*`, `config`, `logging`, `fdr_client`, `clock`, `errors`) or intra-component siblings. Spot-checked all 3 c1_vio strategies + the new c2_vpr helper + the 7 modified c2_vpr strategies. No upward imports detected.
|
||||
2. **Public API respect**: AZ-527's helper is underscore-prefixed (`_engine_dim_assertion.py`) and NOT exported from `c2_vpr/__init__.py` — confirmed. `KltRansacStrategy` and `VinsMonoStrategy` are deliberately NOT exported from `c1_vio/__init__.py` (lazy import only via `runtime_root.vio_factory`) — matches the OKVIS2 precedent and the Risk-2/Risk-3 mitigation pattern. `KltRansacConfig` + `VinsMonoConfig` ARE exported (correct — they participate in the AZ-269 config-loader's structural typing). Verified by `tests/unit/test_az270_compose_root.py::test_ac6_only_compose_root_imports_concrete_strategies` (passes).
|
||||
3. **No new cyclic deps**: built-import graph of changed files + direct dependencies; no cycles introduced. All three c1_vio strategies + the new c2_vpr helper are leaves in the import graph.
|
||||
4. **Duplicate symbols across components**: F1 above is **intra-component** (scoped to `c1_vio/*.py`). No cross-component duplication detected. The c2_vpr helper consolidation explicitly stayed c2-internal — no new cross-component shared symbol introduced.
|
||||
5. **Cross-cutting concerns not locally re-implemented**: AZ-526 + AZ-527 + AZ-508 have moved the genuinely cross-cutting helpers (`iso_ts_now`, `iso_ts_from_clock`) into `helpers/iso_timestamps`. The remaining open intra-component pattern (`c1_vio` orchestration spine, `c2_vpr` engine-dim assertion) is consciously kept component-internal — engine output-shape contracts and strategy state machines are correctly component-scoped concerns, not shared/* concerns. F1's AZ-528 keeps the spine inside `c1_vio/`, not in `shared/helpers`.
|
||||
6. **Native binding location**: VINS-Mono added `src/gps_denied_onboard/components/c1_vio/_native/vins_mono_binding.cpp` next to the facade and `cpp/vins_mono/CMakeLists.txt` for the source build — matches `module-layout.md` rule #4. KLT/RANSAC is pure Python (no `_native/` directory by design) — matches AZ-334's architectural decision. Both gate paths (`BUILD_VINS_MONO`, `BUILD_KLT_RANSAC`) wired correctly at the AZ-331 factory.
|
||||
|
||||
**No Critical, no High Architecture findings in this window.**
|
||||
|
||||
## Verdict Justification
|
||||
|
||||
- Critical findings: 0
|
||||
- High findings: 0
|
||||
- Medium findings: 1 (F1 — already addressed via AZ-528 ticket creation)
|
||||
- Low findings: 1 (F2 — deferred to later hygiene pass; informational carry-forward)
|
||||
|
||||
**PASS_WITH_WARNINGS** — auto-chain to next batch is allowed per implement skill Step 14.5. The F1 finding has an open Jira ticket (AZ-528) ready to be sequenced into a future batch; F2 is informational and does not block.
|
||||
|
||||
## Recommended Follow-up
|
||||
|
||||
1. **Sequence AZ-528 before any future c1_vio strategy or VIO-facing change** (none planned in current scope, but defensively before any AZ-358 / AZ-335 / hypothetical secondary VIO). 3 points, 1 new module + 3 small edits + 1 test.
|
||||
2. **F2 carry-forward**: revisit when the next c1_vio touch lands (e.g. AZ-335 warm-start hint persistence). Sized at 1-2 points. Do NOT bundle into AZ-528 — different abstraction layer.
|
||||
3. **Cumulative-49-51 F2 carry-forward** (AC-10 spec wording drift across AZ-337/338/339/340 specs): still open; documentation-only; fold into any future c2_vpr spec touch.
|
||||
4. **No other carry-over.** All previous cumulative findings are now either CLOSED (B49-51 F1 / F3 closed by AZ-526; B49-51 F1 closed by AZ-527 / B52), tracked (AZ-528 for B52-54 F1), or informational (B49-51 F2 + B52-54 F2).
|
||||
|
||||
## Next Cumulative Review

||||
|
||||

||||

# Code Review Report
|

|
||||
**Batch**: 53 (AZ-333 — C1 VINS-Mono Strategy)
|
||||
**Date**: 2026-05-14
|
||||
**Verdict**: PASS_WITH_WARNINGS
|
||||
|
||||
## Scope
|
||||
|
||||
Single-task batch implementing `VinsMonoStrategy`, the research-only
|
||||
loosely-coupled comparative VIO that participates in the IT-12
|
||||
comparative-study research binary only.
|
||||
|
||||
### Changed files
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/__init__.py` — export
|
||||
`VinsMonoConfig`.
|
||||
- `src/gps_denied_onboard/components/c1_vio/config.py` — add
|
||||
`VinsMonoConfig` dataclass + `vins_mono` field on `C1VioConfig`.
|
||||
- `src/gps_denied_onboard/components/c1_vio/vins_mono.py` — new Python
|
||||
facade (533 lines).
|
||||
- `src/gps_denied_onboard/components/c1_vio/_native/vins_mono_binding.cpp`
|
||||
— new pybind11 binding skeleton (≈275 lines).
|
||||
- `cpp/vins_mono/CMakeLists.txt` — replace placeholder with full
|
||||
pybind11 + linker wiring (≈70 lines).
|
||||
- `tests/unit/c1_vio/conftest.py` — extend with `FakeVinsMonoBackend`
|
||||
+ 3 fake exception types + `fake_vins_mono_binding` fixture.
|
||||
- `tests/unit/c1_vio/test_vins_mono_strategy.py` — new (518 lines)
|
||||
covering AC-1..AC-10 + 2 tier2 perf/honesty tests.
|
||||
- `tests/unit/c1_vio/test_protocol_conformance.py` — drop `vins_mono`
|
||||
from `_STRATEGIES_WITHOUT_PY_MODULE` so the existing parametrised
|
||||
factory test routes through the new strategy correctly.
|
||||
|
||||

||||
| NFR-perf-document | `test_nfr_perf_process_frame_records_p95` (tier2) | ✓ |
|
||||
|
||||
All 10 ACs mapped to tests; test suite reports 17/17 passing for the
|
||||
new `test_vins_mono_strategy.py` (with the 2 tier2 tests skipped on
|
||||
macOS/Linux dev runners as documented in the spec).
|
||||
|
||||
## Phase 3 — Code Quality
|
||||
|
||||
- **SOLID**: `VinsMonoStrategy` has a single responsibility (Python
|
||||
facade for VINS-Mono). Constructor injection per ADR-009. Closed for
|
||||
modification through the AZ-331 Protocol.
|
||||
- **Error handling**: error envelope closed at `VioError` family; no
|
||||
raw backend exception leaks. RuntimeError catch-all for unmapped
|
||||
cases. PASS.
|
||||
- **Naming**: matches the OKVIS2 facade naming exactly (intentional —
|
||||
IT-12 harness substitutability).
|
||||
- **Complexity**: `process_frame` is ~70 lines — same shape as
|
||||
`okvis2.py::process_frame`; not split further because the linear
|
||||
except-ladder is the clearest expression of the rewrap contract.
|
||||
- **DRY**: see F1 below.
|
||||
- **Test quality**: each AC has a behaviourally-meaningful assertion
|
||||
(covariance SPD, frame_id echoed, transition states ordered, etc.).
|
||||
No "did not throw" placeholder tests.
|
||||
- **Dead code**: none.
|
||||
|
||||
## Phase 4 — Security Quick-Scan
|
||||
|
||||
- No SQL / command injection paths. No `subprocess(shell=True)`,
|
||||
`eval`, `exec`.
|
||||
- No hardcoded secrets, API keys, or credentials.
|
||||
- Input validation: numpy array shapes / dtypes validated at the
|
||||
pybind11 boundary (3×3 K, 4×4 pose, length-3 IMU vectors).
|
||||
`VinsMonoConfig.__post_init__` validates all knob ranges.
|
||||
- Sensitive data: per-frame DEBUG log defaults OFF (matches
|
||||
`description.md` § 9 logging hygiene).
|
||||
|
||||
PASS.
|
||||
|
||||
## Phase 5 — Performance Scan
|
||||
|
||||
- Hot path: `process_frame`. IMU push loop is `O(samples_per_window)`
|
||||
— unavoidable.
|
||||
- `get_latest_output` is a single dict copy under a mutex on the C++
|
||||
side; cost is dominated by the numpy view construction (zero-copy).
|
||||
- No N+1, no unbounded buffers (`fdr_client` capacity bounded at 256
|
||||
in tests, real client uses ringbuf from AZ-273).
|
||||
|
||||
PASS.
|
||||
|
||||
## Phase 6 — Cross-Task Consistency
|
||||
|
||||
N/A — single-task batch.
|
||||
|
||||
## Phase 7 — Architecture Compliance
|
||||
|
||||
- **Layer direction**: `vins_mono.py` imports from `_types.nav`,
|
||||
`clock`, `components.c1_vio.errors`, `fdr_client`, `logging` — all
|
||||
L1/L2 substrate per the c1 layering. PASS.
|
||||
- **Public API respect**: `VinsMonoConfig` exported through
|
||||
`c1_vio/__init__.py`; `VinsMonoStrategy` deliberately NOT exported
|
||||
(lazy import only via `runtime_root.vio_factory`) — matches
|
||||
Risk-2/Risk-3 pattern from OKVIS2. PASS.
|
||||
- **No new cyclic dependencies**: introduced module is a leaf — no
|
||||
back-edges to its own importers.
|
||||
- **Native binding location**: `_native/vins_mono_binding.cpp` matches
|
||||
`module-layout.md` rule #4 (binding lives next to facade, native
|
||||
source under `cpp/vins_mono/`).
|
||||
- **Build flag respect**: `BUILD_VINS_MONO=OFF` keeps the binding `.so`
|
||||
out of the build graph and the AZ-331 factory raises
|
||||
`StrategyNotAvailableError` before any import — Risk-3 mitigation
|
||||
intact for airborne / operator-tooling / replay-cli binaries.
|
||||
|
||||
PASS.
|
||||
|
||||
## Findings
|
||||
|
||||
| # | Severity | Category | File:Line | Title |
|
||||
|---|----------|----------|-----------|-------|
|
||||
| 1 | Low | Maintainability | `src/gps_denied_onboard/components/c1_vio/vins_mono.py` | Structural duplication with `okvis2.py` (~80% mirrored) — tracked for future hygiene PBI after AZ-334 lands |
|
||||
| 2 | Low | Maintainability | `tests/unit/c1_vio/conftest.py` | `FakeVinsMonoBackend` mirrors `FakeOkvis2Backend` ~1:1 — same deferred-consolidation note |
|
||||
|
||||
### Finding details
|
||||
|
||||
**F1: Structural duplication of strategy facade** (Low / Maintainability)
|
||||
|
||||
- Location: `src/gps_denied_onboard/components/c1_vio/vins_mono.py` vs
|
||||
`src/gps_denied_onboard/components/c1_vio/okvis2.py`
|
||||
- Description: The new `VinsMonoStrategy` mirrors `Okvis2Strategy`
|
||||
~80% verbatim — the constructor wiring, `_classify_state`,
|
||||
`_tick_lost`, `_emit_transition`, `_build_vio_output`, `_bias_norm`,
|
||||
`_now_iso`, `_se3_from_4x4`, `_frame_ts_ns`, `_frame_image`, and the
|
||||
full `process_frame` except-ladder are byte-equivalent modulo the
|
||||
exception class names and producer ID. This is intentional for now
|
||||
because (a) the AZ-331 factory + IT-12 comparative harness require
|
||||
the two to be drop-in substitutable, (b) the consolidation target
|
||||
is ill-defined until KltRansacStrategy lands (AZ-334 — fundamentally
|
||||
different shape: pure-Python, no native binding), and (c) extracting
|
||||
a base class now would force premature coupling between the
|
||||
research-only and production-default strategies.
|
||||
- Suggestion: defer consolidation to a hygiene PBI scheduled AFTER
|
||||
AZ-334 lands. At that point all three strategy shapes are visible
|
||||
and the right factoring (template method? composition over a shared
|
||||
state-machine helper?) will be obvious. Mirrors the AZ-340 → AZ-527
|
||||
precedent for c2_vpr secondary strategies. Track informally; do
|
||||
NOT create the PBI yet — the next cumulative review (batches 52-54)
|
||||
will surface this naturally.
|
||||
- Task: AZ-333
|
||||
|
||||
**F2: Test fake duplication** (Low / Maintainability)
|
||||
|
||||
- Location: `tests/unit/c1_vio/conftest.py` (`FakeVinsMonoBackend`
|
||||
vs `FakeOkvis2Backend`)
|
||||
- Description: `FakeVinsMonoBackend` is a near-copy of
|
||||
`FakeOkvis2Backend` with renamed exceptions. The shared
|
||||
`ScriptedOutput` dataclass + `_make_default_payload` helper IS
|
||||
reused (good — the productive cut), but the backend class itself
|
||||
duplicates the queue-driven scripting pattern. Same deferred
|
||||
consolidation note as F1; both should be addressed together so the
|
||||
facade-side base class and the test-side base fake align.
|
||||
- Suggestion: same as F1 — defer to the post-AZ-334 hygiene PBI.
|
||||
- Task: AZ-333
|
||||
|
||||
## Verdict
|
||||
|
||||
**PASS_WITH_WARNINGS** — two Low-severity duplication findings, both
|
||||
intentionally-deferred for the post-AZ-334 hygiene PBI. No Critical,
|
||||
High, or Medium findings. All 10 ACs covered with passing tests. The
|
||||
unrelated `c12_operator_orchestrator/test_cli_console_script.py::test_cold_start_under_500ms_p99`
|
||||
failure observed in the full-suite run is a pre-existing
|
||||
environment-dependent perf flake (worst-after-trim 997 ms vs 500 ms
|
||||
threshold on macOS dev runner) with no touchpoint to c1_vio; reported
|
||||
to the user, not blocking this batch.

# Code Review Report
|
||||
|
||||
**Batch**: 54 (AZ-334 — C1 KLT/RANSAC Strategy)
|
||||
**Date**: 2026-05-14
|
||||
**Verdict**: PASS_WITH_WARNINGS
|
||||
|
||||
## Scope
|
||||
|
||||
Single-task batch implementing `KltRansacStrategy`, the mandatory
|
||||
simple-baseline `VioStrategy` that satisfies the ADR-002 engine rule
|
||||
(every component MUST ship a simple-baseline strategy alongside its
|
||||
production-default). Pure-Python over OpenCV's `cv2.goodFeaturesToTrack`
|
||||
/ `cv2.calcOpticalFlowPyrLK` / `cv2.findEssentialMat` / `cv2.recoverPose`
|
||||
path; no C++/pybind11 native binding by design — Tier-0 workstation can
|
||||
run the strategy with `pip install opencv-python` only.
|
||||
|
||||
### Changed files
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/klt_ransac.py` — new
|
||||
Python facade (~770 lines, including module docstring + AC mapping
|
||||
+ risk-mitigation notes).
|
||||
- `src/gps_denied_onboard/components/c1_vio/config.py` — add
|
||||
`KltRansacConfig` dataclass + `klt_ransac` field on `C1VioConfig`;
|
||||
`__all__` updated; `KNOWN_STRATEGIES` already had `klt_ransac`.
|
||||
- `src/gps_denied_onboard/components/c1_vio/__init__.py` — export
|
||||
`KltRansacConfig`.
|
||||
- `cpp/klt_ransac/CMakeLists.txt` — replace placeholder message
|
||||
with a deliberate "pure-Python; no native target" explanation so
|
||||
the build graph stays symmetric with `cpp/okvis2/` and
|
||||
`cpp/vins_mono/` while the `BUILD_KLT_RANSAC=ON` flag only gates
|
||||
the Python module import at the AZ-331 composition-root factory.
|
||||
- `tests/unit/c1_vio/test_klt_ransac_strategy.py` — new test module
|
||||
covering AC-1..AC-11 + NFR-perf (~990 lines, 25 tests; 23 pass + 2
|
||||
tier-2 skipped on dev/CI runners).
|
||||
- `tests/unit/c1_vio/test_protocol_conformance.py` — introduce the
|
||||
`_STRATEGIES_WITHOUT_NATIVE_BINDING` category and route
|
||||
`klt_ransac` through it inside `test_ac5_build_vio_strategy_flag_on_but_module_missing`
|
||||
so the parametrised factory test correctly handles the pure-Python
|
||||
shape (no native binding to fail on).

All 11 ACs + NFR-perf mapped to passing tests. Test suite reports
|

25 tests, 23 pass + 2 tier2 skipped on the standard dev/CI runner;
|
||||
all 25 pass under `GPS_DENIED_TIER=2`. Adjacent regression:
|
||||
`tests/unit/c1_vio/` reports 95 passed + 6 skipped (6 = the 2
|
||||
KLT-tier2 + 2 OKVIS2-tier2 + 2 VINS-Mono-tier2 tests); config-loader
|
||||
and compose-root suites green (17 passed).
|
||||
|
||||
## Phase 3 — Code Quality
|
||||
|
||||
- **SOLID**: `KltRansacStrategy` has a single responsibility (Python
|
||||
facade over OpenCV's KLT/RANSAC path). Constructor injection per
|
||||
ADR-009 — `Config` + `FdrClient` enter explicitly; `Clock` is
|
||||
optional with a `WallClock` default; the AZ-276 `ImuPreintegrator`
|
||||
is constructed lazily on the first `process_frame` call (it
|
||||
requires the per-call `CameraCalibration` which is not available
|
||||
at constructor time — matches the existing factory pattern across
|
||||
OKVIS2 / VINS-Mono).
|
||||
- **Error handling**: error envelope closed at the `VioError` family;
|
||||
every OpenCV `cv2.error` is caught at each call site and rewrapped
|
||||
into `VioFatalError` with `__cause__` chaining (AC-4). Pose-recovery
|
||||
failures route through `_pose_recovery_failed` which raises
|
||||
`VioInitializingError` until `lost_frame_threshold` is exhausted,
|
||||
then escalates to `VioFatalError` (AC-7). RansacFilterError +
|
||||
ImuPreintegrationError are also caught and rewrapped.
|
||||
- **Naming**: matches the OKVIS2 / VINS-Mono facade naming exactly
|
||||
(intentional — IT-12 harness substitutability).
|
||||
- **Complexity**: `process_frame` is ~120 lines; the dominant cost is
|
||||
the explicit step-numbered ladder (IMU push → grayscale → first-frame
|
||||
branch → KLT track → RANSAC filter → essential-matrix → pose recover
|
||||
→ covariance → VioOutput build → state classify → re-seed features).
|
||||
Splitting further would obscure the linear flow that maps 1:1 onto
|
||||
the task spec's "Outcome" numbered list.
|
||||
- **DRY**: structural duplication with OKVIS2 / VINS-Mono facades —
|
||||
see F1 below; deliberately deferred to the post-batch-54 hygiene
|
||||
PBI (now scheduled by the next cumulative review, batches 52-54).
|
||||
- **Test quality**: each AC has a behaviourally-meaningful assertion
|
||||
(covariance SPD, frame_id echoed, transition states ordered,
|
||||
monotonic covariance growth during DEGRADED, etc.). No "did not
|
||||
throw" placeholder tests. AC-3 / AC-6 / AC-9 / AC-10 / AC-11 /
|
||||
NFR-perf monkeypatch `cv2.findEssentialMat` + `cv2.recoverPose`
|
||||
+ `RansacFilter.filter_correspondences` to deterministic values so
|
||||
the unit suite exercises the FACADE's state machine without
|
||||
depending on real OpenCV geometry on synthetic correspondences;
|
||||
real-geometry validation lives in C1-IT-12 (Jetson Tier-2 fixture).
|
||||
- **Dead code**: none. `_drain_into_list` removed from the test
|
||||
helper after the simpler `_drain` was introduced.
|
||||
|
||||
## Phase 4 — Security Quick-Scan
|
||||
|
||||
- No SQL / command injection paths. No `subprocess(shell=True)`,
|
||||
`eval`, `exec`.
|
||||
- No hardcoded secrets, API keys, or credentials.
|
||||
- Input validation: `_intrinsics_3x3` rejects non-3x3 K with
|
||||
`VioFatalError`; `_grayscale` rejects unsupported image shapes;
|
||||
`KltRansacConfig.__post_init__` validates every knob range
|
||||
(max_corners ≥ 4, klt_window_size_px odd ≥ 3, klt_pyramid_levels
|
||||
≥ 1, min_features_for_pose ≥ 5, ransac_inlier_ratio in (0, 1],
|
||||
essential_matrix_ransac_threshold_px > 0).
|
||||
- Sensitive data: per-frame DEBUG log defaults OFF
|
||||
(`KltRansacConfig.per_frame_debug_log = False`) — matches
|
||||
`description.md` § 9 logging hygiene.
|
||||
|
||||
PASS.
|
||||
|
||||
## Phase 5 — Performance Scan
|
||||
|
||||
- Hot path: `process_frame`. IMU push loop is
|
||||
`O(samples_per_window)` — unavoidable. KLT track + RANSAC are
|
||||
multi-threaded internally by OpenCV; bound at 30 % of one core
|
||||
per ADR-002 budget partition.
|
||||
- No N+1, no unbounded buffers (FdrClient capacity bounded by
|
||||
AZ-273 ringbuf; the strategy keeps a single
|
||||
`_prev_features` numpy array sized at `max_corners`).
|
||||
- Covariance estimator: `_estimate_covariance` does one
|
||||
`np.eye(6) * scalar` — O(1).
|
||||
- AC-9 honest-covariance: the residual_var / DOF formula has no
|
||||
client-side floor; cov Frobenius grows monotonically as
|
||||
inlier_count drops (verified in tier-2 test).
|
||||
|
||||
PASS.
|
||||
|
||||
## Phase 6 — Cross-Task Consistency
|
||||
|
||||
N/A — single-task batch. Cross-task consistency with AZ-332 +
|
||||
AZ-333 is tracked in the next cumulative review (batches 52-54),
|
||||
which will see all three strategy facades and the duplication
|
||||
finding (F1) at the same time.
|
||||
|
||||
## Phase 7 — Architecture Compliance
|
||||
|
||||
- **Layer direction**: `klt_ransac.py` imports from `_types.nav`,
|
||||
`_types.calibration` (TYPE_CHECKING only), `clock.wall_clock`,
|
||||
`components.c1_vio.config` (TYPE_CHECKING only),
|
||||
`components.c1_vio.errors`, `fdr_client`, `helpers.imu_preintegrator`,
|
||||
`helpers.ransac_filter`, `logging` — all L1/L2 substrate per the
|
||||
c1 layering. PASS.
|
||||
- **Public API respect**: `KltRansacConfig` exported through
|
||||
`c1_vio/__init__.py`; `KltRansacStrategy` deliberately NOT exported
|
||||
(lazy import only via `runtime_root.vio_factory`) — matches the
|
||||
Risk-2/Risk-3 pattern from OKVIS2 and VINS-Mono. PASS.
|
||||
- **No new cyclic dependencies**: introduced module is a leaf — no
|
||||
back-edges to its own importers.
|
||||
- **Native binding location**: NONE by design. `cpp/klt_ransac/`
|
||||
carries a CMakeLists that returns a STATUS message documenting
|
||||
the absence of native target; the directory is preserved for
|
||||
build-graph symmetry with `cpp/okvis2/` and `cpp/vins_mono/`.
|
||||
- **Build flag respect**: `BUILD_KLT_RANSAC=OFF` keeps the
|
||||
composition-root factory from importing the strategy module; the
|
||||
AZ-331 factory raises `StrategyNotAvailableError` before any
|
||||
import — Risk-3 mitigation intact for operator-tooling binaries
|
||||
(which do not need any VIO at all).
|
||||
- **AC-11 camera agnostic**: source CI-grep gate verifies no
|
||||
`adti20` / `adti26` literals in executable code (docstrings are
|
||||
excluded via AST-aware stripping in the test). PASS.
|
||||
|
||||
PASS.

||||

## Findings
|
||||
|
||||
| # | Severity | Category | File:Line | Title |
|
||||
|---|----------|----------|-----------|-------|
|
||||
| 1 | Low | Maintainability | `src/gps_denied_onboard/components/c1_vio/klt_ransac.py` | Structural duplication with `okvis2.py` / `vins_mono.py` — now scheduled for post-batch-54 hygiene PBI via cumulative review |
|
||||
| 2 | Low | Maintainability | `tests/unit/c1_vio/test_klt_ransac_strategy.py` | `_patch_pose_recovery` helper is bespoke per-strategy; the same patching pattern could plausibly be shared with OKVIS2 / VINS-Mono fake-binding fixtures |
|
||||
|
||||
### Finding details
|
||||
|
||||
**F1: Structural duplication of strategy facade** (Low / Maintainability)
|
||||
|
||||
- Location: `src/gps_denied_onboard/components/c1_vio/klt_ransac.py`
|
||||
vs `src/gps_denied_onboard/components/c1_vio/okvis2.py` /
|
||||
`vins_mono.py`
|
||||
- Description: The new `KltRansacStrategy` mirrors `Okvis2Strategy`
|
||||
+ `VinsMonoStrategy` ~70 % verbatim on the orchestration spine —
|
||||
`_classify_state`, `_tick_lost`, `_emit_transition`,
|
||||
`_bias_norm`, `_now_iso`, `_se3_from_4x4`, the constructor strategy-
|
||||
label guard, and the FDR record-emit shape are byte-equivalent
|
||||
modulo strategy-label constants. The geometry-specific pipeline
|
||||
(KLT seed/track, RANSAC filter, findEssentialMat, recoverPose,
|
||||
residual-scatter covariance) IS unique to this strategy and lives
|
||||
in its own module — that boundary is correct. The shared
|
||||
orchestration spine is the consolidation target tracked by the
|
||||
hygiene PBI deferred since batch 53; the cumulative review
|
||||
scheduled for batches 52-54 (next trigger) will formally raise the
|
||||
PBI now that all three strategy shapes are visible.
|
||||
- Suggestion: defer (one more time) to the cumulative review for
|
||||
batches 52-54 — the right factoring is now visible (template-
|
||||
method base class for the orchestration spine + per-strategy
|
||||
geometry hook). Do NOT create the PBI ad-hoc here; let the
|
||||
cumulative review own the cross-batch refactor scope.
|
||||
- Task: AZ-334
|
||||
|
||||
**F2: Test patching helper could be shared** (Low / Maintainability)
|
||||
|
||||
- Location: `tests/unit/c1_vio/test_klt_ransac_strategy.py`
|
||||
(`_patch_pose_recovery`) vs `tests/unit/c1_vio/conftest.py`
|
||||
(`FakeOkvis2Backend` / `FakeVinsMonoBackend`)
|
||||
- Description: KLT/RANSAC uses real OpenCV bindings (no fake-binding
|
||||
fixture) so the existing conftest fakes don't apply directly. The
|
||||
per-test helper `_patch_pose_recovery` does the equivalent job of
|
||||
forcing a deterministic-success path. This is a different
|
||||
abstraction shape from the conftest fakes but lives at the same
|
||||
layer; consolidating with the post-batch-54 hygiene PBI would let
|
||||
all three strategies share a single per-strategy "ScriptedSuccess"
|
||||
fixture surface.
|
||||
- Suggestion: same as F1 — let the cumulative review's hygiene PBI
|
||||
own the cross-cutting test-fixture refactor.
|
||||
- Task: AZ-334
|
||||
|
||||
## Verdict
|
||||
|
||||
**PASS_WITH_WARNINGS** — two Low-severity duplication findings, both
|
||||
intentionally deferred and now formally in scope for the next
|
||||
cumulative review (batches 52-54). No Critical, High, or Medium
|
||||
findings. All 11 ACs + NFR-perf covered with passing tests.
|
||||

||||
Pre-existing environment-dependent perf flake noted in batch 53
|
||||
(`tests/unit/c12_operator_orchestrator/test_cli_console_script.py::test_cold_start_under_500ms_p99`)
|

is still environmental and untouched by this batch — reported, not

# Code Review Report
|

|

**Batch**: 55 (AZ-528 — c1_vio strategy facade orchestration-spine consolidation)
|
||||
**Date**: 2026-05-14
|
||||
**Verdict**: PASS
|
||||
|
||||
## Scope
|
||||
|
||||
Single-task hygiene batch closing Finding F1 from
|
||||
`_docs/03_implementation/cumulative_review_batches_52-54_cycle1_report.md`.
|
||||
Replaces the 3-way byte-equivalent orchestration-spine duplication
|
||||
across `okvis2.py`, `vins_mono.py`, `klt_ransac.py` with a single
|
||||
c1-internal helper module `_facade_spine.py`. No behaviour change;
|
||||
existing AZ-332 / AZ-333 / AZ-334 AC tests pass unmodified.
|
||||
|
||||
### Changed files
|
||||
|
||||
- `src/gps_denied_onboard/components/c1_vio/_facade_spine.py` — NEW
|
||||
c1-internal helper. Exports 5 stateless free functions (`now_iso`,
|
||||
`bias_norm`, `se3_from_4x4`, `frame_ts_ns`, `frame_image`) and one
|
||||
mixin class (`FacadeSpine`) providing `_classify_state`,
|
||||
`_tick_lost`, `_emit_transition`. 225 lines including docstring +
|
||||
attribute declarations.
|
||||
- `src/gps_denied_onboard/components/c1_vio/okvis2.py` — inherit from
|
||||
`FacadeSpine`; import the 5 free functions; delete the 5 local
|
||||
module-level definitions + 3 instance methods + unused
|
||||
`_BIAS_NORM_FLOOR` constant; set 3 new spine-required attributes in
|
||||
`__init__` (`_feature_threshold`, `_producer_id`, `_strategy_label`).
|
||||
- `src/gps_denied_onboard/components/c1_vio/vins_mono.py` — same
|
||||
pattern as `okvis2.py`.
|
||||
- `src/gps_denied_onboard/components/c1_vio/klt_ransac.py` — same
|
||||
pattern; reuses `_grayscale` (KLT/RANSAC-specific, not consolidated).
|
||||
Spine threshold attribute reads `_cfg.min_features_for_pose` (the
|
||||
KLT-side equivalent of OKVIS2's `degraded_feature_threshold`).
|
||||
- `tests/unit/c1_vio/test_az528_facade_spine.py` — NEW. 19 tests
|
||||
covering AC-1..AC-8 + a Risk-1 mitigation test that statically
|
||||
verifies every concrete strategy's `__init__` sets every
|
||||
spine-required attribute.
|
||||
|
||||

|
||||
|
||||
Test counts:
|
||||
|
||||
- `tests/unit/c1_vio/test_az528_facade_spine.py` — 19 tests, all pass.
|
||||
- `tests/unit/c1_vio/` total — 120 collected, 114 pass + 6 tier-2
|
||||
skipped (unchanged from pre-AZ-528 state).
|
||||
- Adjacent regression suite (`test_az270_compose_root`, `test_az272_fdr_record_schema`,
|
||||
`test_az273_fdr_client_ringbuf`, `test_ac1_scaffold_layout`,
|
||||
`tests/unit/c1_vio/`) — 237 pass + 6 skipped.
|
||||
|
||||
Scope discipline: only the 5 files in the task spec's "Included"
|
||||
list were touched; no test files outside the new
|
||||
`test_az528_facade_spine.py` were modified (AC-9 hard requirement).
|
||||
|
||||
## Phase 3 — Code Quality
|
||||
|
||||
- **SRP**: `FacadeSpine` owns one responsibility — the c1_vio
|
||||
strategy state machine + FDR `vio.health` record emission. Free
|
||||
functions are stateless pure utilities. Each concrete strategy
|
||||
retains its geometry pipeline + native-binding driver. Clean split.
|
||||
- **Naming**: instance attributes the mixin reads are documented in
|
||||
the class docstring; type annotations on the class declare them for
|
||||
IDE / type-checker consumption (Risk 1 mitigation).
|
||||
- **Comments**: deferred-consolidation comments referencing this PBI
|
||||
(`# post-AZ-334 hygiene PBI ...`) were removed from
|
||||
`klt_ransac.py` as required by the task spec.
|
||||
- **Dead code**: removed `_BIAS_NORM_FLOOR` from `okvis2.py` (verified
|
||||
via grep; not used anywhere in the c1_vio component or
|
||||
cross-component).
|
||||
- **DRY**: the consolidation eliminates ~120 lines of duplicated code
|
||||
across the three strategy modules.
|
||||
- **Test quality**: every test follows Arrange / Act / Assert; AC
|
||||
tests use parametrisation where appropriate (AC-8 over the 3
|
||||
strategy modules).
|
||||
|
||||
## Phase 4 — Security Quick-Scan
|
||||
|
||||
N/A — pure refactor, no new inputs, no I/O, no string interpolation
|
||||
into queries, no subprocess invocation. The free functions take only
|
||||
typed DTOs (`ImuBias`, `NavCameraFrame`, `np.ndarray`); the mixin
|
||||
methods only mutate instance state.
|
||||
|
||||
## Phase 5 — Performance
|
||||
|
||||
No hot-path regression. The mixin call sites are byte-equivalent to
|
||||
the previous in-line definitions (same conditionals, same
|
||||
`FdrClient.enqueue` invocation, same string interpolation in
|
||||
`bias_norm`). The single new indirection is method dispatch through
|
||||
the mixin's MRO — Python class-method resolution is O(1) on a fixed
|
||||
MRO and is amortised inside the hot-path's existing call overhead.
|
||||
|
||||
## Phase 6 — Cross-Task Consistency
|
||||
|
||||
Single-task batch — N/A.
|
||||
|
||||
## Phase 7 — Architecture Compliance
|
||||
|
||||
- **Layer direction**: `_facade_spine.py` imports only from L1
|
||||
substrate (`_types.nav`, `components.c1_vio.errors`,
|
||||
`fdr_client.records`) + stdlib (`datetime`, `math`) + numpy. No
|
||||
imports from a higher layer; no imports from a sibling component.
|
||||
- **Public API respect**: `_facade_spine` is underscore-prefixed and
|
||||
NOT in `c1_vio/__init__.py`'s `__all__`. AZ-270's
|
||||
`test_ac6_only_compose_root_imports_concrete_strategies`
|
||||
regression-gate passes. Mirrors the AZ-527 precedent for
|
||||
`_assert_engine_output_dim` in `c2_vpr`.
|
||||
- **Cycles**: no new cyclic dependencies. `_facade_spine` is a leaf
|
||||
inside `c1_vio`; the 3 strategy modules already imported from
|
||||
`c1_vio.errors`, so the new sibling import slots in cleanly.
|
||||
- **Duplicate symbols**: AC-8 AST regression guard asserts the 5
|
||||
consolidated free-function names appear only in `_facade_spine.py`.
|
||||
- **Cross-cutting concerns**: the spine is a c1-internal concern by
|
||||
task-spec decision (component state machines + per-strategy FDR
|
||||
record producers do not generalise across c2..c5; AZ-507 carved
|
||||
that boundary intentionally). NOT hoisted to `shared/helpers/`.
|
||||
|
||||
## Findings
|
||||
|
||||
None.
|
||||
|
||||
## Conclusion
|
||||
|
||||
PASS. The consolidation removes ~120 lines of duplication, preserves
|
||||
behaviour across all three strategies (verified by 237 passing tests
|
||||
in the focused + adjacent suite), and respects the c1_vio component
|
||||
boundary. The cumulative review batches 52-54 Finding F1 is closed.
|
||||
|
||||
Risk 4 (mixin couples future divergence) is mitigated by the task
|
||||
spec's documented escape hatch: future divergent strategies can
|
||||
either override mixin methods or use the free functions in isolation.
|
||||
The 3 current strategies' state machines are byte-equivalent
|
||||
post-refactor, so the mixin is the right shape today.

### Finding Details
|
||||
|
||||
**F1: AC-3 log kind shorthand vs source-suffixed kind** (Low / Style)
|
||||
|
||||
- Location: `src/gps_denied_onboard/runtime_root/warm_start_wiring.py:82`, mirrored in `_emit_prime_log` k-builder
|
||||
- Description: AZ-335 spec **AC-3** requires `INFO log kind="c1.warm_start.cold_start"`. The spec **Outcome §** also names the cold-start *source* tag as `cold_start_no_hint` (line 44 of `AZ-335_c1_warm_start_recovery.md`). The implementation builds the log kind as `f"c1.warm_start.{source}"` to keep the family namespace consistent (so all three sources — `f2_takeoff_fc`, `f8_reboot_disk`, `cold_start_no_hint` — produce log kinds that match their FDR `source` field). The result is `c1.warm_start.cold_start_no_hint`, which is more discriminating than the AC-3 shorthand but doesn't match it character-for-character.
|
||||
- Suggestion: Either (a) tighten AC-3's spec text in the next revision of `AZ-335_c1_warm_start_recovery.md` to say `c1.warm_start.cold_start_no_hint`, or (b) emit `c1.warm_start.cold_start` and keep the FDR record's `source` field as `cold_start_no_hint`. Option (a) preferred — the source-suffixed kind is genuinely more useful for log filtering.
|
||||
- Task: AZ-335
|
||||
|
||||
**F2: Per-frame save uses strategy-frame pose as `body_T_world`** (Medium / Maintainability)
|
||||
|
||||
- Location: `src/gps_denied_onboard/runtime_root/warm_start_wiring.py:267-272` (`_save_hint_from_output`)
|
||||
- Description: AZ-335 spec line 41 says "every emitted `VioOutput` from `process_frame` is converted into a `WarmStartPose` (relative-pose chained against the prior baseline by the runtime root, plus the latest `imu_bias` from the same `VioOutput`)". Per `_types.nav.VioOutput` docstring, `relative_pose_T` is "the strategy's current pose ... expressed in the strategy's own internal frame". The implementation passes `out.relative_pose_T` straight into `WarmStartPose.body_T_world` without composing against a takeoff baseline. This is **semantically defensible** because the strategy's "internal frame" persists across F8 reload: at F2 takeoff the FC EKF seeds the strategy's frame to world, and on F8 reload the saved hint reinstalls that same frame's most-recent pose so the strategy "continues from where it left off". But the spec phrasing implies an explicit baseline-compose step that the wiring layer would own. No AC tests this composition, so the gap is informational, not contractual.
|
||||
- Suggestion: Either (a) document the design choice inline in `_save_hint_from_output` (a 3-line comment explaining why the strategy-frame pose IS the right hint without explicit composition), or (b) revise the spec line 41 prose in cycle 2 to match the as-built behaviour. Recommend (a) — adds zero runtime cost, prevents future maintainers from "fixing" the gap.
|
||||
- Task: AZ-335
|
||||
|
||||
**F3: NFR perf tests are dev-hardware smoke** (Low / Spec-Gap)
|
||||
|
||||
- Location: `tests/unit/c1_vio/test_az335_warm_start.py::TestStoreNfrPerf`
|
||||
- Description: Spec NFR-perf-save (p99 ≤ 50 ms) and NFR-perf-load (p99 ≤ 20 ms) are explicitly Tier-2-NVMe budgets. The unit test uses 200 iterations on whatever filesystem `tmp_path` resolves to (developer hardware) and asserts the p99 is below the same threshold. This is sufficient to catch egregious regressions but is NOT the production NFR check.
|
||||
- Suggestion: Tier-2 measurement is the responsibility of `C1-PT-01` (Tier-2 perf gate; deferred to E-BBT). Keep the dev smoke as-is; do not expand here.
|
||||
- Task: AZ-335
|
||||
|
||||
**F4: `runtime_root` imports c1-internal `_facade_spine`** (Low / Architecture)
|
||||
|
||||
- Location: `src/gps_denied_onboard/runtime_root/warm_start_wiring.py:54`
|
||||
- Description: `runtime_root/warm_start_wiring.py` imports `bias_norm` and `now_iso` from `gps_denied_onboard.components.c1_vio._facade_spine`. Per `module-layout.md` §6 + §9, `runtime_root` is the composition root and may import any component's internal modules — so this is **allowed**. The note is recorded because importing an underscore-prefixed (c1-internal-by-convention) module from runtime_root is unusual: most runtime_root files only import each component's `interface.py` plus the concrete strategy modules.
|
||||
- Rationale for the choice: the AZ-335 wiring emits `vio.warm_start` FDR records that share the same `kind="vio.*"` namespace and timestamp/bias-norm conventions as the c1-strategy-internal `vio.health` records (AZ-528 / `_facade_spine`). Sharing the producer functions guarantees forensic logs across the family stay byte-identical in formatting. Inlining the two helpers in `warm_start_wiring.py` would introduce 6 lines of duplication and a future drift risk.
|
||||
- Suggestion: Keep the import. If a future cycle wants to formalize, promote `bias_norm` + `now_iso` into a shared helper module (e.g., `helpers/iso_timestamps.py` already exists for ISO-8601 handling per AZ-526; `bias_norm` could move to `helpers/imu_bias.py`).
|
||||
- Task: AZ-335

|

(AZ-334). Closes cumulative review batches 52-54 Finding F1: the
|

orchestration-spine duplication across the c1_vio strategy triplet.
|
||||
|
||||
Mirrors the AZ-527 precedent for the c2_vpr-side consolidation —
|
||||
underscore-prefixed module name keeps the helper c1-internal (NOT in
|
||||
``c1_vio/__init__.py``'s Public API surface); concrete strategies
|
||||
import it as a sibling. Engine output-shape contracts and VIO state
|
||||
machines are component-scoped concerns, NOT cross-component
|
||||
``shared/helpers/`` concerns.
|
||||
|
||||
The helper module exposes:
|
||||
|
||||
Free functions (stateless, pure):
|
||||
|
||||
- :func:`now_iso` — ISO-8601 UTC timestamp for FDR record ``ts``.
|
||||
- :func:`bias_norm` — L2 norm of the concatenated ``(accel || gyro)``
|
||||
6-vector.
|
||||
- :func:`se3_from_4x4` — lazy ``gtsam.Pose3`` construction from a
|
||||
4x4 row-major matrix.
|
||||
- :func:`frame_ts_ns` — UTC-epoch nanoseconds from
|
||||
:class:`NavCameraFrame` (OKVIS2 + VINS-Mono only; KLT/RANSAC owns
|
||||
inline grayscale conversion via its geometry pipeline).
|
||||
- :func:`frame_image` — contiguous ``uint8`` ndarray with 2D/3D
|
||||
shape validation. ``producer_id`` is parametrised so the error
|
||||
message names the originating strategy.
|
||||
|
||||
Mixin (:class:`FacadeSpine`) provides the state-machine + FDR
|
||||
``vio.health`` record emit. Concrete strategies inherit from it
|
||||
and set the per-instance attributes the mixin reads:
|
||||
|
||||
- ``_reported_state``, ``_frames_since_warmup``,
|
||||
``_warm_start_max_frames``, ``_feature_threshold`` — used by
|

:meth:`FacadeSpine._classify_state`.
|

- ``_consecutive_lost``, ``_lost_frame_threshold`` — used by

:meth:`FacadeSpine._tick_lost`.

in ``__init__``) before any of the mixin methods are called:

- ``_reported_state: VioState``
|

- ``_frames_since_warmup: int``
|

- ``_warm_start_max_frames: int``

- ``_consecutive_lost: int``
|

- ``_lost_frame_threshold: int``
|

- ``_last_emitted_state: VioState | None``
|

- ``_producer_id: str`` — FDR record ``producer_id`` field
|
||||
(e.g. ``"c1_vio.okvis2"``).
|
||||
- ``_strategy_label: str`` — FDR payload ``strategy_label``
|
||||
field (e.g. ``"okvis2"``).
|
||||
- ``_latest_bias: ImuBias``
|
||||
- ``_fdr: FdrClient``
|
||||
|

Type annotations on the class declare the attributes for static

type-checkers; missing assignments at runtime surface as

Pure-Python facade over OpenCV's pyramidal Lucas-Kanade optical-flow +

essential-matrix RANSAC path. The ADR-002 engine-rule mandatory

baseline: every airborne binary MUST link a simple-baseline strategy
|

alongside the production-default. KLT/RANSAC is the lowest-complexity
|

strategy in E-C1 by code volume — no C++/pybind11, no native binding —
|
||||
so a Tier-0 workstation can run it with only ``pip install opencv-python``
|
||||
and the AZ-331 factory's ``BUILD_KLT_RANSAC=ON`` gate.
|
||||
|
||||
Conforms to the AZ-331 :class:`VioStrategy` Protocol; consumes the
|
||||
runtime ``Config`` + an :class:`FdrClient`; constructs its other
|
||||
dependencies (logger, KLT/RANSAC sub-config, IMU preintegrator) from
|

``config`` so the strategy class matches the composition-root factory
|
||||
shape::
|
||||
|
||||
strategy_cls(config: Config, *, fdr_client: FdrClient)
|
||||
|
||||
This mirrors :class:`Okvis2Strategy` (AZ-332) + :class:`VinsMonoStrategy`
|
||||
(AZ-333) deliberately: the AZ-331 factory produces all three via the
|
||||
same ``(config, *, fdr_client)`` shape and the IT-12 comparative-study
|
||||
harness expects them to be drop-in substitutable. The structural
|
||||
duplication of the constructor / state machine / error-rewrap ladder
|
||||
is tracked for the post-AZ-334 hygiene PBI (Batch 53 review F1).
|

|

AC mapping (see ``_docs/02_tasks/done/AZ-334_c1_klt_ransac_strategy.md``):
|
||||
|

- AC-1 : :meth:`current_strategy_label` returns ``"klt_ransac"``.
|
||||
- AC-2 : First :meth:`process_frame` emits :class:`VioOutput` with
|
||||
identity relative pose, conservative INIT-state covariance, and
|
||||
``health_snapshot().state == INIT``.
|
||||
- AC-3 : Steady-state :meth:`process_frame` emits :class:`VioOutput`
|
||||
with non-identity relative pose, SPD covariance, ``mre_px > 0``.
|
||||
- AC-4 : ``cv2.error`` from :func:`cv2.findEssentialMat` /
|
||||
:func:`cv2.recoverPose` rewraps into :class:`VioFatalError` with a
|
||||
``__cause__`` chain; no raw ``cv2.error`` leaks.
|
||||
- AC-5 : :meth:`reset_to_warm_start` clears the feature buffer +
|
||||
re-seeds the IMU bias via the AZ-276 preintegrator's
|
||||
:meth:`reset_with_bias`; idempotent across consecutive calls.
|
||||
- AC-6 : Inlier loss → :class:`VioState.DEGRADED` + monotonically
|
||||
growing covariance Frobenius norm; :class:`VioOutput` IS emitted
|
||||
(not raised).
|
||||
- AC-7 : ``lost_frame_threshold`` consecutive failed-pose frames →
|
||||
:class:`VioFatalError`; ``health_snapshot().state == LOST``.
|
||||
- AC-8 : ``BUILD_KLT_RANSAC=OFF`` does not import this module —
|
||||
enforced by AZ-331's factory in
|
||||
:mod:`gps_denied_onboard.runtime_root.vio_factory`;
|
||||
``StrategyNotAvailableError`` is the surfaced error.
|
||||
- AC-9 : Honest covariance — no shrinkage during DEGRADED; the
|
||||
per-frame covariance is the residual-scatter formula divided by
|
||||
the inlier-DOF (``N_inliers - 5``) with no client-side floor or
|
||||
smoother.
|
||||
- AC-10: Exactly one ``vio.health`` FDR record per state transition;
|
||||
no spam on steady-state.
|
||||
- AC-11: Camera-agnostic source — no ``adti20`` / ``adti26`` literals;
|
||||
the per-call :class:`CameraCalibration` argument carries intrinsics.
|
||||
|
||||
Risk mitigations (see task spec for full text):
|
||||
|
||||
- *Risk 1 — residual-scatter under-reports during high-overlap straight
|
||||
flight*: documented; the C1-IT-12 comparative-study report cross-
|
||||
validates against OKVIS2. No code mitigation in this strategy.
|
||||
- *Risk 2 — KLT track loss on first frame*: AC-2 handles INIT state +
|
||||
FDR record on transition.
|
||||
- *Risk 3 — RANSAC threshold sensitivity*: surfaced via
|
||||
``KltRansacConfig.essential_matrix_ransac_threshold_px``; the
|
||||
AZ-282 :class:`RansacFilter` pre-filter runs at the
|
||||
``essential_matrix_ransac_threshold_px`` boundary, then
|
||||
:func:`cv2.findEssentialMat`'s internal RANSAC runs again on the
|
||||
surviving inlier set — two stages with separate determinism gates.
|
||||
- *Risk 4 — RESTRICT-UAV-3 sharp turns*: DEGRADED reported immediately;
|
||||
recovery is F6 satellite re-localisation (E-C2 / E-C3 / E-C4 path).

the IT-12 comparative-study harness expects the two to be drop-in

|

SHA-256 sidecar persistence via :class:`Sha256Sidecar` (AZ-280).

- :class:`WarmStartFcSource` (PEP 544 Protocol) — the consumer-side

structural cut over the C8 ``FcAdapter`` family that

Protocol cuts live with the consumer.

always ``1`` for this cycle. The schema layout is documented inline

inflation to a strategy would double-inflate when the wiring also

inflates (Constraints, AZ-335 task spec).

3. When a baseline floor was installed by

:meth:`prime_post_reboot`, post-reset frames are additionally

scaled up so their Frobenius norm is at least the saved

pre-reboot value (AC-8 — the "no fake confidence" invariant).

The wrapper is itself a :class:`VioStrategy` (PEP 544 structural

typing). ``runtime_checkable`` conformance is verified by the

AZ-335 unit tests; downstream consumers (C5 fusion, C13 FDR)
|
||||
cannot tell the difference between the wrapped and the bare
|
||||
strategy because the public Protocol shape is preserved.
|
||||
|

Per-frame save errors do NOT crash the process — a
|
||||
:class:`Sha256SidecarError` or :class:`OSError` raised by
|
||||
:meth:`WarmStartHintStore.save` is logged at ERROR (kind
|
||||
``c1.warm_start.save_failed``) and swallowed so the camera

ingest hot path keeps flowing (AC-NFR-no-crash).

"""AZ-528 — c1_vio facade orchestration-spine consolidation tests.

|

Covers AC-1..AC-8 of
|
||||
``_docs/02_tasks/todo/AZ-528_hygiene_c1_vio_facade_spine_consolidation.md``:
|
||||
|
||||
- AC-1: helper module exposes the documented surface.
|
||||
- AC-2: ``now_iso()`` returns an aware UTC ISO-8601 timestamp with
|
||||
``+00:00`` offset (NOT the ``Z``-suffix variant — that is
|
||||
``iso_ts_from_clock`` in AZ-526).
|
||||
- AC-3: ``bias_norm`` matches the L2 formula on a hand-checked vector.
|
||||
- AC-4: ``se3_from_4x4`` builds a ``gtsam.Pose3`` with the expected
|
||||
identity rotation + zero translation when fed ``np.eye(4)``.
|
||||
- AC-5: ``FacadeSpine._classify_state`` returns INIT during warm-up,
|
||||
TRACKING above the threshold, DEGRADED below it.
|
||||
- AC-6: ``FacadeSpine._tick_lost`` demotes TRACKING → DEGRADED on the
|
||||
first lost frame and escalates to LOST at the threshold.
|
||||
- AC-7: ``FacadeSpine._emit_transition`` emits exactly one
|
||||
``vio.health`` FDR record per state change (no record on
|
||||
steady-state).
|
||||
- AC-8: AST-walk regression guard — zero module-level definitions of
|
||||
the consolidated free functions remain in any of the three strategy
|
||||
modules. Mirrors the AZ-508 / AZ-526 / AZ-527 pattern.
|
||||
|
||||
AC-9 (existing AZ-332 / AZ-333 / AZ-334 AC tests pass unmodified) and
|
||||
AC-10 (AZ-270 layer lint) ride the existing test files; this module
|
||||
does not re-stage them.
