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.
