Roll/pitch ±30° round-trips are + tested to confirm the decomposition. +* **AZ-412 ground footprint** — default 147 m is derived from + `camera_info.md` (~141 m alt, ~55° HFOV).

All others under 30. +- **Tests assert behaviour**, not just "no exception": geodesic round-trips against real distances, boundary conditions (exactly 48/60, exactly 0.95 ratio, exactly 2.5 px) are explicitly tested. +- **Spec drift guard**: each helper has a `test_constants_match_spec` test that fails if the public constants drift from the AC text (catches a renamer that touches code but forgets the spec). +- **Boundary strictness**: AC-2 of FT-P-05 says "MRE < 2.5 px"; the helper uses strict `<` and the test `test_evaluate_per_image_budget_single_fail_fails_overall` proves a 2.5 px reading FAILS. This is the kind of boundary the spec would otherwise be ambiguous on. + +### Phase 4 — Security + +No SQL, no subprocess, no credentials. CSV loaders validate header columns explicitly; numeric coercion via `float()` / `int()` raises on garbage input. + +### Phase 5 — Performance + +- All three helpers operate on per-flight-sized data (60 images, ≤14700 frames, ≤4900 IMU rows). Pure-Python loops are fine. +- `mre_evaluator.evaluate_p95` uses `numpy.percentile` (vectorised). +- No new I/O patterns beyond CSV read/write. + +### Phase 6 — Cross-Task Consistency + +- **API stability**: the three new helpers share the same shape pattern as AZ-410's `anchor_pair_detector` and AZ-411's `estimate_schema` — typed `@dataclass(frozen=True)` records, a `load_…` reader, an `evaluate(…)` / `compute_…` core, a `write_csv_evidence` emitter. The FT-P-05 scenario reuses `accuracy_evaluator.evaluate()` (AZ-409) to compute per-image error_m → demonstrates the cross-task consistency in action. +- **No duplicate symbols across batches**: each helper module owns disjoint public names; the only shared dependency is `runner.helpers.geo.distance_m`. +- **Scenario-file skip pattern**: all 4 new scenario files (`test_ft_p_01_*`, `test_ft_p_04_*`, `test_ft_p_05_*`, `test_ft_p_06_*`) reuse the `_harness_helpers_implemented` gate pattern from batch 69. Consistent. +- **Within-batch dep (AZ-413 → AZ-412)**: FT-P-06 reads FT-P-04's CSV (the f2f MRE column). The mre_evaluator's `load_frame_to_frame_csv` explicitly validates that the `mre_px` column is present; if absent (FT-P-04 evidence not yet carrying MRE), FT-P-06 fails with a clear message pointing at the SUT contract (AC-NEW-3 FDR schema). This is the safest failure mode for an inter-task dep. + +### Phase 7 — Architecture Compliance + +1. **Layer direction**: every new file under `e2e/**`. The `test_no_sut_imports.py` invariant (passes after the run) confirms zero `gps_denied_onboard` imports across all 14 new files. +2. **Public API respect**: only public names imported across modules (`runner.helpers.{geo,accuracy_evaluator,mre_evaluator}` etc.). No leading-underscore cross-module imports. +3. **No new cyclic dependencies**: import graph: + - `accuracy_evaluator` → `geo` + - `registration_classifier` → (none) + - `mre_evaluator` → (numpy + stdlib) + - `tests.positive.test_ft_p_01_*` → `accuracy_evaluator` + - `tests.positive.test_ft_p_04_*` → `registration_classifier` + - `tests.positive.test_ft_p_05_*` → `accuracy_evaluator` + `mre_evaluator` + - `tests.positive.test_ft_p_06_*` → `mre_evaluator` + Linear DAG. +4. **Duplicate symbols across components**: none. +5. **Cross-cutting concerns**: pytest plugin registration unchanged from batch 69 (the new helpers don't need a plugin — they're called from scenario test bodies). + +No Architecture findings. + +Baseline delta section omitted (no `architecture_compliance_baseline.md` for this project). + +## AC Test Coverage Summary + +| Task | ACs Covered (unit) | NOT COVERED (harness-loop) | Test File | +|------|---------------------|----------------------------|-----------| +| AZ-409 | 1, 2, 3, 4, 5 | Runtime push-to-SITL end-to-end | `test_accuracy_evaluator.py` (20 tests) | +| AZ-412 | 1, 2, 3, 4 | Runtime full Derkachi replay | `test_registration_classifier.py` (26 tests) | +| AZ-413 | 1, 2, 3, 4, 5 | Runtime push-to-SITL end-to-end | `test_mre_evaluator.py` (22 tests) | + +## Verdict: PASS + +No Critical, High, Medium, or Low findings.
