Per-replacement geodesic offset + enforced to ≥350 m (AC-2 of FT-N-01 / AC-NEW-8 envelope). +* **blackout_spoof.py** — writes a `schedule.json` with paired + `(window_start_ms, window_end_ms, blackout_frame_indices, spoof_gps)` + artefacts. The schedule's spoofed-GPS track satisfies AC-NEW-8 (200–500 m + consecutive deltas), AC-4 (fix_type ∈ {3, 4}, hdop ∈ [0.5, 2.5], no + sentinels), and AC-3 (max alignment err 40 ms recorded; enforced by + the runtime proxy). Black frames are pinned-PIL all-zero 256×256 JPEGs. +* **multi_segment.py** — produces ≥3 disjoint blackout windows + uniformly anchored at fractions of the source duration, with + enforced ≥30 s inter-segment gaps and ≤25 % total coverage. No spoof + injection (FT-P-08 positive path). +* **fc_proxy.py** — stateless pass-through proxy with timed splice; + `activate(now_ms_provider, first_blackout_ms)` aligns the proxy + clock to the video-overlay's first black frame so AC-3 (≤40 ms) holds + end-to-end. Pre-activate `process_inbound_message()` is a `RuntimeError` + (programming-error guard, not silent passthrough). +* **`_common.py`** — `derive_rng(domain, *components)` is the + domain-tagged seed primitive; `read_tile_manifest` parses the + AZ-407 manifest.csv (with derived lat/lon centres via the slippy XYZ + inverse) so injectors can pick "far-away" replacement tiles without + importing the tile-cache-builder package; `haversine_m` / + `far_away_indices` are a deliberate light-weight duplicate of + `geo.distance_m` (pyproj) so injectors run in minimal Docker images + without the heavier geo extras. +* **pytest fixtures**: `runner/helpers/injector_fixtures.py` exposes + `outlier_injection_derkachi`, `blackout_spoof_derkachi`, + `multi_segment_derkachi` plus the shared `derkachi_source_frames`, + `tile_cache_fixture` lookups. Registered via the runner conftest's + `pytest_plugins`. + +### AZ-410 — FT-P-02 cumulative drift between satellite anchors (3pt) + +* **`runner/helpers/anchor_pair_detector.py`** — pure-Python helper + with the AC-1 detection (segment-then-anchor pair construction), + AC-2/AC-3 pass-fraction computation, AC-4 bin-median monotonicity + check, plus a Vincenty-WGS84 drift computation via + `runner.helpers.geo.distance_m`. Default age bins follow the spec's + `{<1 s, 1-3 s, 3-10 s, 10-30 s, >30 s}` buckets. `aggregate(stream)` + is the one-call entry-point the scenario uses; `write_csv_evidence` + emits the FT-P-02 evidence CSV. +* **`tests/positive/test_ft_p_02_derkachi_drift.py`** — pytest scenario + parameterized across `(fc_adapter, vio_strategy)`; the docker-bound + runtime path is gated by `_harness_helpers_implemented`, which + probes `runner.helpers.frame_source_replay` / `fdr_reader` / + `imu_replay` for `NotImplementedError`. When the upstream helpers + land the scenario activates with zero further changes. + +### AZ-411 — FT-P-03 + FT-P-14 schema + WGS84 (2pt) + +* **`runner/helpers/estimate_schema.py`** — three pure validators: + `validate_estimate_schema` (AC-1: `lat:float`, `lon:float`, + `cov_semi_major_m:float`, `last_satellite_anchor_age_ms:int` present + & well-typed; bool-leaks-as-int explicitly rejected), + `validate_source_label` (AC-2: set ⊆ {`satellite_anchored`, + `visual_propagated`, `dead_reckoned`}), `validate_wgs84_range` (AC-3: + lat ∈ [-90, 90], lon ∈ [-180, 180], NaN rejected).

Implementation + followed the module-layout entry (consistent with batch 68's AZ-407 + resolution). The AZ-408 archived spec retains the `tests/fixtures` + wording for audit; the actual file ownership is `e2e/fixtures/`. +* **AZ-410 spec mentions `tests/fixtures/...` in the AC-NEW table** + (single mention of `tests/integration/fdr_reader.py`). Same + resolution — module-layout authoritative. +* **AZ-408 AZ-406-scaffold-dataclass divergence**: the AZ-406 scaffold + declared `OutlierInjectionPlan(target_segment_seconds, max_offset_m, + n_outliers)`; AZ-408 needs `(source_frames_dir, tile_cache_dir, + density, seed, min_offset_m)`. The contract test was updated together + with the scaffold replacement (no other callers of the old shape + existed; verified by `rg`). This is the expected scaffold-to-real + evolution per the AZ-406 injector docstrings ("Concrete generator + is owned by AZ-408"). +* **AZ-410 / AZ-411 runtime-path skip**: both scenario files probe + `NotImplementedError` from `frame_source_replay` / `imu_replay` / + `fdr_reader` / `sitl_observer` / `mavproxy_tlog_reader` rather than + hard-coding a "deferred until AZ-X" marker. When those helpers + land, both scenarios activate automatically. + +## Test Results + +### Focused tests (Step 6.4) + +`pytest e2e/_unit_tests/` — **248 passed in 141.08s** (was 157 at end +of batch 68;

All other functions are short. +- Tests assert behaviour (window length, geodesic offset, schema field presence) not "no exception" — meaningful. +- Dead code: removed obsolete `OutlierInjectionPlan.target_segment_seconds/n_outliers` (AZ-406 scaffold field) — the contract test was updated to the new shape. + +### Phase 4 — Security +No SQL, no subprocess(shell=True), no credentials, no deserialization.

Acceptable in unit-test context. +- `anchor_pair_detector` is O(N) over the FDR stream; bin computation is O(N + bins). +- `estimate_schema` validators are O(1) per record; aggregate is O(N). + +### Phase 6 — Cross-Task Consistency +- AZ-408's `_common.derive_rng` is consumed by both `outlier` and `blackout_spoof` — shared seed discipline. +- AZ-410's `anchor_pair_detector` uses `runner.helpers.geo.distance_m` (pyproj WGS84) — consistent with the project's existing distance helper. +- AZ-411's `estimate_schema` does not overlap with `anchor_pair_detector` (different concerns: schema/transport vs trajectory analysis). +- All three new helper modules under `runner/helpers/` are independent — no inter-module imports between AZ-410 and AZ-411 deliverables. Tests cover the helpers independently. +- Scenario files (`test_ft_p_02_*`, `test_ft_p_03_14_*`) share the same `_harness_helpers_implemented` pattern (probe NotImplementedError on upstream helpers; skip with clear reason). Consistent style. + +### Phase 7 — Architecture Compliance +- **Layer direction**: every new file under `e2e/**`; no imports of `gps_denied_onboard.*` — verified by the `test_no_sut_imports.py` invariant (passes). The blackbox_tests cross-cutting entry in module-layout.md sits outside the production layering table; this batch respects its envelope. +- **Public API respect**: `_common.py` is a private module (leading underscore) consumed only by the three injectors; cross-injector consumption goes through documented public names (`derive_rng`, `cleanup_tmpfs`, `tmpfs_root`, `read_tile_manifest`, `haversine_m`, `far_away_indices`). +- **No new cyclic dependencies**: import graph is linear — `outlier`/`blackout_spoof`/`multi_segment` → `_common`; `fc_proxy` is standalone; `injector_fixtures` → injectors; scenario files → `runner.helpers.{anchor_pair_detector,estimate_schema}` only. +- **Duplicate symbols**: `_common.haversine_m` is a deliberate duplicate of the project's `geo.distance_m` (Vincenty); the docstring explains the reason — injectors run in minimal Docker images without pyproj, while the runner image always has pyproj. Acceptable. +- **Cross-cutting concerns**: pytest plugin registration (`injector_fixtures` added to `pytest_plugins`) follows the existing pattern from `csv_reporter` / `evidence_bundler` / `nfr_recorder`. + +No Architecture findings. + +Baseline delta: `_docs/02_document/architecture_compliance_baseline.md` does not exist for this project — baseline delta section omitted. + +## AC Test Coverage Summary + +| Task | ACs Covered | Test File(s) | Notes | +|------|-------------|--------------|-------| +| AZ-408 | 1, 2, 3, 4, 5, 6 | `test_outlier.py`, `test_blackout_spoof.py`, `test_multi_segment.py`, `test_fc_proxy.py`, `test_injectors_contract.py` | 60 new unit tests; all pass | +| AZ-410 | 1, 2, 3, 4, 5 (collection) | `test_anchor_pair_detector.py` | 15 new unit tests; runtime AC-1.3 hardware-loop NOT COVERED (docker harness leftover) | +| AZ-411 | 1, 2, 3, 4 (collection) | `test_estimate_schema.py` | 18 new unit tests; runtime single-image push NOT COVERED (docker harness leftover) | + +## Code Review Verdict: PASS + +No Critical, High, Medium, or Low findings.
