From c6e6cba237da1377f2143ff0dfd24a58a25195fe Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Sun, 17 May 2026 07:12:24 +0300 Subject: [PATCH] [AZ-414] [AZ-415] [AZ-418] Test batch 71: sharp turn + multi-segment + smoothing - AZ-414 (FT-P-07 + FT-N-02): sharp_turn_detector helper covering AC-1 (gyro_z run detection + synthetic-overlay fallback), AC-2/AC-3 (FT-N-02 during-turn label + monotonic covariance), AC-4/AC-5/AC-6 (FT-P-07 recovery lag/drift/heading); twin scenario files under positive/ and negative/. - AZ-415 (FT-P-08): multi_segment_evaluator helper + scenario. - AZ-418 (FT-P-10): smoothing_evaluator helper covering AC-1 (raw + smoothed pose pairing), AC-2 (improvement rate >= 0.80), AC-3 (mean improvement >= 5 m); scenario file. - All scenarios skip-gated on upstream frame_source_replay / imu_replay / fdr_reader stubs (auto-activate when AZ-441 + AZ-407 leftovers land). - +68 unit tests; full e2e unit suite: 393 passed.

The split + is at the *assertion* layer (positive vs negative scenario file), not + at the detector. `smoothing_evaluator` owns pose-pair logic, GT + resolution, and budget evaluation. `multi_segment_evaluator` already + reviewed in batch 71 partial. +* **No suppressed errors**: every helper raises on invalid input + (`get_threshold_mdps` env validation, `pair_records` dupe/unknown + pose_kind, `load_zgyro_samples` missing column, `synthesize_overlay_segment` + argument validation, `evaluate` empty GT track). +* **AAA comment discipline**: every test uses `# Arrange / # Act / + # Assert`; sections omitted when not needed (single-line `Assert` for + constant tests). +* **No narration comments**: docstrings explain non-obvious intent + (AC mapping, why orphans are excluded, why nearest-neighbour GT is + acceptable, why the env override exists). + +### Phase 4 — Security + +* **No SUT imports**: confirmed by passing `test_no_sut_imports.py` in + the full suite. None of the new modules import from + `src.gps_denied_onboard`. +* **No PII/credentials**: helpers handle synthetic + Derkachi-public + GT only. +* **No SQL/shell injection surface**: helpers consume CSV via + `csv.DictReader` and `pathlib`. No subprocess calls. + +### Phase 5 — Performance + +* All helpers are O(N) over samples. `pair_records` is one dict pass; + `evaluate` is O(P) over paired keyframes (P typically ≤200 for the + Derkachi window); `detect_turn_segments` is one scan; + `evaluate_ft_p_07` uses a linear scan for pre-anchor + recovery + (acceptable for ≤1000 samples; if scenario data grows we can switch + to bisect). +* No nested CSV reads or repeated geodesic recomputations. + +### Phase 6 — Cross-Task Consistency + +* **Pattern parity with batches 69 + 70**: + - Skip gate (`_harness_helpers_implemented` fixture) for missing + upstream replay helpers — same pattern as `test_ft_p_02_*`, + `test_ft_p_04_*`, `test_ft_p_05_*`. + - `_NullSink` / `_NullImuEmitter` probes — same pattern as `test_ft_p_04_*`. + - Evidence CSV via `write_csv_evidence(out, …)` returning the path — + same pattern as `accuracy_evaluator`, `mre_evaluator`, + `multi_segment_evaluator`. + - NFR metrics via `nfr_recorder.record_metric(name, value, ac_id=…)` — + same pattern as `test_ft_p_01_*`, `test_ft_p_04_*`. + - Helper modules importable from `runner.helpers.*` with module-level + constants in `UPPER_SNAKE` — matches `multi_segment_evaluator` and + `mre_evaluator`. +* **No drift**: FT-P-07 scenario reuses the `MAX_RECOVERY_FRAMES_SAFETY_MS` + budget constant from the helper (no magic numbers); FT-N-02 reuses + `ALLOWED_DURING_TURN_LABELS` set so the scenario assertion message + prints the spec-accurate alphabetised set. + +### Phase 7 — Architecture Compliance + +* **Public-boundary discipline**: confirmed by `test_no_sut_imports.py` + (passing). Helpers consume only the FDR record schema (record_type + + payload dict) defined in `runner.helpers.fdr_reader`. +* **Directory layout**: new files added to `test_directory_layout.py` + parametrize list (`runner/helpers/{smoothing_evaluator,sharp_turn_detector,multi_segment_evaluator}.py`, + `tests/positive/test_ft_p_{07,08,10}_*.py`, + `tests/negative/test_ft_n_02_*.py`). All 75 parametrized variants + pass. +* **Determinism**: all helpers are deterministic — no `time.time()`, no + random number generation; `random` not imported in any new module. + +### Phase 8 — Test Suite Health + +* Total: **393 passed in 126.64s** (was 325 at end of batch 70). +* New tests this batch: **+68** (sharp_turn_detector: 30; smoothing_evaluator: 15; multi_segment_evaluator: 16; directory_layout new entries: 7). +* Pre-existing macOS-only `/e2e-results` plugin issue still present — + affects scenario test invocation outside Docker only; unit suite + unaffected.
