# Batch 71 Report — Test Implementation (cycle 1, batch 5 of test phase)
|
||||
|
||||
**Batch**: 71
|
||||
**Date**: 2026-05-16
|
||||
**Context**: Test implementation (greenfield Step 10 — Implement Tests)
|
||||
**Tasks**: AZ-414 (3pt), AZ-415 (3pt), AZ-418 (3pt) — 9 cp / 3 tasks
|
||||
**Cycle**: 1
|
||||
**Verdict**: COMPLETE — PASS (self-reviewed; see `reviews/batch_71_review.md`)
|
||||
|
||||
## Summary
|
||||
|
||||
Three scenarios covering sharp-turn recovery (positive + negative twin),
|
||||
multi-segment relocalisation, and GTSAM smoothing-loop look-back. Same
|
||||
pattern as batches 69 + 70:
|
||||
|
||||
* Pure-logic helper under `e2e/runner/helpers/` for everything the
|
||||
scenario can express without docker-bound replay + FDR ingestion.
|
||||
* Scenario file(s) under `e2e/tests/{positive,negative}/`,
|
||||
parameterized across `(fc_adapter, vio_strategy)`, skip-gated on
|
||||
upstream `frame_source_replay` / `imu_replay` / `fdr_reader` stubs
|
||||
(auto-activates when AZ-441 + AZ-407 leftovers land).
|
||||
* Helper-driven unit test file under `e2e/_unit_tests/helpers/`.
|
||||
|
||||
### AZ-414 — FT-P-07 + FT-N-02 sharp-turn recovery + failure twin (3pt)
|
||||
|
||||
* **`runner/helpers/sharp_turn_detector.py`** — `load_zgyro_samples`
|
||||
reads `SCALED_IMU2.zgyro` (millidegree/s) from `data_imu.csv`;
|
||||
`get_threshold_mdps` reads the AC-3.2 threshold from env var
|
||||
`AC32_SHARP_TURN_GYRO_Z_MDPS` (default 30,000 mdps) per spec note;
|
||||
`detect_turn_segments` finds contiguous runs of ≥3 samples above
|
||||
threshold (using `|zgyro|` so left + right turns both qualify);
|
||||
`synthesize_overlay_segment` provides the AC-1 fallback when the
|
||||
natural fixture has no qualifying turn; `detect_or_synthesize` is the
|
||||
scenario-facing helper that picks natural-first; `evaluate_ft_n_02`
|
||||
computes AC-2 (label ∈ {visual_propagated, dead_reckoned}) + AC-3
|
||||
(cov non-decreasing); `evaluate_ft_p_07` computes AC-4 (recovery
|
||||
lag ≤ 3 frames safety-budget = 1100 ms), AC-5 (drift ≤ 200 m), AC-6
|
||||
(heading delta ≤ 70°). `write_csv_evidence` emits a combined CSV
|
||||
with `synthetic_overlay` column so the fallback fact is recorded per
|
||||
AC-1.
|
||||
* **`tests/positive/test_ft_p_07_sharp_turn_recovery.py`** — asserts
|
||||
AC-4 + AC-5 + AC-6 per segment; records NFR metrics with AC IDs;
|
||||
records `synthetic_overlay` flag.
|
||||
* **`tests/negative/test_ft_n_02_sharp_turn_failure.py`** — asserts
|
||||
AC-2 + AC-3 per segment; uses the same detector + frame-collection
|
||||
logic.
|
||||
* **30 unit tests** in `test_sharp_turn_detector.py`.
|
||||
|
||||
### AZ-415 — FT-P-08 multi-segment relocalisation (3pt)
|
||||
|
||||
* **`runner/helpers/multi_segment_evaluator.py`** — `load_schedule`
|
||||
reads the AZ-408 multi-segment schedule (blackout window times +
|
||||
recovery anchors); `evaluate_window` checks AC-2 (label =
|
||||
dead_reckoned inside window), AC-3 (recovery to satellite_anchored
|
||||
≤ 10 s after window end), AC-4 (no centre jump > 200 m at recovery);
|
||||
`evaluate` aggregates over all blackout windows; constants
|
||||
`MAX_RECOVERY_LAG_MS = 10_000` and `MAX_JUMP_M = 200.0` expose the
|
||||
thresholds.
|
||||
* **`tests/positive/test_ft_p_08_multi_segment_reloc.py`** — drives
|
||||
`multi-segment-derkachi` injector fixture, replays via stub-gated
|
||||
helpers, evaluates per window.
|
||||
* **16 unit tests** in `test_multi_segment_evaluator.py`.
|
||||
|
||||
### AZ-418 — FT-P-10 GTSAM smoothing-loop look-back accuracy (3pt)
|
||||
|
||||
* **`runner/helpers/smoothing_evaluator.py`** — `pair_records` groups
|
||||
FDR `keyframe_pose` records by `keyframe_id` and rejects duplicate
|
||||
`pose_kind` values (raw + smoothed must be exactly one each per
|
||||
keyframe per AC-1); `resolve_gt_at` picks the nearest-in-time
|
||||
Derkachi GLOBAL_POSITION_INT pose (10 Hz cadence → ≤50 ms slop
|
||||
acceptable for the metre-scale improvement deltas this AC
|
||||
measures); `evaluate` produces per-keyframe + aggregate report with
|
||||
`improvement_rate` (AC-2 threshold = 0.80) and `mean_improvement_m`
|
||||
(AC-3 threshold = 5 m). The module docstring explicitly preserves
|
||||
Mode B Fact #107 — this is an INTERNAL improvement metric, NOT
|
||||
FC-side retroactive correction.
|
||||
* **`tests/positive/test_ft_p_10_smoothing_lookback.py`** — pairs +
|
||||
evaluates + asserts AC-2 + AC-3 per (fc_adapter, vio_strategy).
|
||||
* **15 unit tests** in `test_smoothing_evaluator.py`.
|
||||
|
||||
## Tests
|
||||
|
||||
* **Full e2e unit suite**: 393 passed in 126.64 s (was 325 at end of
|
||||
batch 70 → +68 net new tests this batch).
|
||||
* **Pre-existing**: macOS-only `/e2e-results` plugin issue in scenario
|
||||
invocation outside Docker. Unit suite unaffected. Tracked under
|
||||
runner reporting — out of batch scope.

||||

## Findings Sweep
|
||||
|
||||
### Phase 1 — Context Loading
|
||||
|
||||
Loaded specs `AZ-414_ft_p_07_ftn_02_sharp_turn.md`,
|
||||
`AZ-415_ft_p_08_multi_segment_reloc.md`,
|
||||
`AZ-418_ft_p_10_smoothing_lookback.md`. Reused the existing `geo.py`,
|

`sharp_turn_detector.py` (new this batch), `multi_segment_evaluator.py`
|
||||
(new this batch), `smoothing_evaluator.py` (new this batch), and the
|

`fdr_reader` / `frame_source_replay` / `imu_replay` stub gates used by
|
||||
batches 69 and 70. Re-read `_docs/00_problem/input_data/flight_derkachi/data_imu.csv`
|

header layout to confirm `SCALED_IMU2.zgyro` column and `GLOBAL_POSITION_INT.lat/lon`
|
||||
units (decimal degrees, not 1e-7 int32).
|

|
||||
### Phase 2 — Spec Compliance

||||
|
||||
Mode B Fact #107 ("INTERNAL improvement metric; NOT FC-side retroactive
|
||||
correction") explicitly preserved in module docstring.
|
||||
|
||||
### Phase 3 — Code Quality
|
||||
|
||||
* **Single responsibility**: each helper is one concern. `sharp_turn_detector`
|
||||
owns detection + per-segment evaluation for both FT-P-07 (recovery) and
|
||||
FT-N-02 (during turn) because both halves consume the same segment
|
||||
fixture and the same outbound-estimate stream — splitting them would
|
||||
duplicate `TurnFrameSample` collection in two scenarios. 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. Tracked under runner reporting (out of batch scope).
|
||||
|
||||
## Cross-Task Consistency Verdict
|
||||
|
||||
PASS — no cross-task drift, no duplicated logic across the three new
|
||||
helpers, no shared mutable state, evidence CSV schemas distinct per
|
||||
scenario but follow the same write pattern.
|
||||
|
||||
## Architecture Compliance Verdict
|
||||
|
||||
PASS — public-boundary blackbox stance preserved; no SUT imports; FDR
|
||||
schema honoured.
|
||||
|
||||

"""FT-P-07 — Sharp-turn recovery via satellite reference (AZ-414 / AC-3.2).
|

|

The full scenario:
|
||||
|
||||
1. Identify the sharp-turn segment in the Derkachi flight via
|
||||
``SCALED_IMU2.zgyro`` spikes (≥3 consecutive rows above the AC-3.2
|
||||
threshold). If none exist, fall back to a synthetic-gyro overlay
|
||||
(the choice is recorded in the evidence CSV per AC-1).
|
||||
2. Replay the Derkachi MP4 + IMU stream through the SUT.
|
||||
3. Collect outbound estimates with source_label + cov_semi_major_m.
|
||||
4. Per turn segment, evaluate:
|
||||
* AC-4: recovery to ``satellite_anchored`` within ≤3 frames after
|
||||
turn end (safety-budget converted to ms in the helper).
|
||||
* AC-5: drift between propagated centre at turn end and recovery
|
||||
anchor centre ≤200 m.
|
||||
* AC-6: heading delta (pre-anchor → propagated-end → recovery)
|
||||
stays in [0°, 70°].
|
||||
5. Assert FT-P-07 passes per ``(fc_adapter, vio_strategy)`` (AC-7).
|
||||
|
||||
FT-N-02 (the negative twin) is owned by
|
||||

the same detection + ``TurnFrameSample`` collection logic via
