From a1185d0a28cd04be5d6ea018ef639b8c6dd8ad14 Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Thu, 14 May 2026 04:09:22 +0300 Subject: [PATCH] [AZ-345] [AZ-346] [AZ-347] [AZ-349] C3 matchers + C3.5 AdHoP refiner Implement the three concrete C3 CrossDomainMatcher strategies plus the C3.5 production-default AdHoPRefiner. C3 (AZ-345/346/347): - DiskLightGlueMatcher + AlikedLightGlueMatcher share a single shared _pipeline.run_lightglue_pipeline orchestrator (decode -> query extract -> per-candidate loop -> RANSAC sort -> health update -> FDR emit) so the only per-backbone delta is the keypoint+descriptor extractor closure. ALIKED adds a create-time engine output-schema probe (AC-special-1). - XFeatMatcher owns its own per-candidate loop (single forward fuses extraction + matching); it re-uses the shared FDR emission helpers to keep telemetry byte-identical across strategies. lightglue_runtime parameter accepted by factory but discarded (AC-special-1). - All three consume the shared LightGlueRuntime / RansacFilter / RollingHealthWindow helpers; no helper forks. InferenceRuntimeCut consumer-side Protocol added per AZ-507. C3.5 (AZ-349): - AdHoPRefiner implements the <= conditional gate, runs the OrthoLoC AdHoP TRT engine over best-candidate correspondences, re-runs RANSAC on the perspective-preconditioned set, and emits an enriched MatchResult with refinement_label="adhop". - Invariant 4 passthrough fall-through: any RefinerBackboneError (TRT failure, OOM, NaN, bad shape) is caught, logged ERROR, FDR-emitted with error: true, and converted to passthrough that still counts against the rolling invocation-rate window. MemoryError and other non-listed exceptions propagate by design (AC-5 closed-set semantics). - Rolling 60-s invocation-rate window + rate-limited WARN log (configurable via ratelimited_warn_window_ns; default 60 s). Shared changes: - C3MatcherConfig + C3_5RefinerConfig extended with the new weights/threshold/window fields. - matcher_factory + refiner_factory optionally forward clock + fdr_client to the strategy's create(); backward-compatible. - fdr_client.records registers five new kinds: matcher.frame_done, matcher.backbone_error, matcher.insufficient_inliers, matcher.all_failed, refiner.frame_done. Tests: 66 new (43 C3 parametrised + 23 AdHoP) covering 47/47 ACs; focused suite green; full project test suite green except for one pre-existing flaky CLI cold-start timing test unrelated to this batch.

XFeat (AZ-347) uses a different per-candidate loop because its backbone fuses extraction + matching into one pass, but it still re-uses four error/emission helpers (`_emit_backbone_error`, `_emit_frame_done`, `_emit_insufficient_inliers`, `_fail_all`) for FDR-byte-identical telemetry. The underscore prefix on these helpers means "internal to `c3_matcher`" — sibling files importing them is permitted by Python convention, but readers may assume `_pipeline` is private to its `__all__` exports. +- Suggestion: (a) Add a docstring note in `_pipeline.py` that lists the in-component consumers of the underscore helpers, OR (b) drop the leading underscore from the four helpers (they are component-internal but cross-file public). Option (a) preferred — keeps the surface unchanged. +- Task: AZ-347 + +**F2: Probe tensor dtype is FP32; production ALIKED engines may be FP16** (Low / Maintainability) + +- Location: `src/gps_denied_onboard/components/c3_matcher/_engine_output_assertion.py:60` +- Description: `assert_keypoint_engine_output_schema` allocates a zero-init probe with `dtype=np.float32`. Production ALIKED engines compiled by C10 (AZ-321) use `PrecisionMode.FP16` per `_build_aliked_build_config()`. If a TRT engine's input binding rejects an FP32 tensor (TRT 10.x is strict about binding dtype), the probe will fail at startup with a confusing error rather than the intended schema check. +- Suggestion: Follow the C2 pattern (`assert_engine_output_dim` uses `np.float16` for FP16 backbones); thread the engine's input dtype through `assert_keypoint_engine_output_schema` and synthesise the probe in the matching dtype. Alternative: probe with FP16 by default and document the assumption. No fix required this cycle — the existing tests cover the schema-mismatch path with a fake runtime that accepts any dtype. +- Task: AZ-346 + +**F3: AZ-347 AC-special-2 is informational, not tested** (Low / Scope) + +- Location: `_docs/02_tasks/todo/AZ-347_c3_xfeat.md:91-94` +- Description: The task spec explicitly marks AC-special-2 as "informational metric; if XFeat is NOT faster, that's a backbone misconfiguration, not a contract violation. Documented in the test report; does NOT block this AC." No test exists today. Flagged for traceability so the omission is visible in the next cumulative review. +- Suggestion: No action. Latency benchmarks belong to C3-PT-01 (E-BBT, deferred). Documented here to keep the AC coverage matrix honest. +- Task: AZ-347 + +## Verdict + +**PASS_WITH_WARNINGS** — every AC has a covering test; the three Low findings are observability / future-proofing concerns, not contract violations or runtime bugs. No Critical / High / Architecture findings. + +Auto-fix would not improve any of the Low findings without expanding scope.
