No bare `except` + in any new module. +* **AAA comment discipline**: every test uses `# Arrange / # Act / + # Assert`; sections omitted when not needed. +* **No narration comments**: docstrings explain non-obvious intent + (AC mapping, why orphans excluded, why `materialize_to_list` exists, + why `EK3_SRC1_POSXY = 3` is the only acceptance value). + +### Phase 4 — Security + +* **No SUT imports**: confirmed by `test_no_sut_imports.py` (passing in + the full suite). None of the new modules import from + `src.gps_denied_onboard`. +* **Signing handshake stance**: the helper does NOT validate signatures + itself (that's pymavlink's job); it only counts signed-frame arrivals + and `BAD_SIGNATURE` STATUSTEXT incidents. If signing fails in any way + AC-1 fails — the scenario does NOT bypass to an unsigned channel + (per spec "Forbidden" list). +* **No secrets in source**: the AP scenario looks up + `mavlink-test-passkey.txt` from the on-disk fixture (already + verified by `test_passkey_files_match` in `test_directory_layout.py`). + The passkey itself is the AZ-407 / AZ-408 fixture, NOT a production + key. +* **No SQL/shell injection surface**: all helpers operate on bytes / + pathlib / dict; no subprocess calls in the helper layer (subprocess + for `msp_gps_toy` is the SITL-observer's responsibility). + +### Phase 5 — Performance + +* `mavproxy_tlog_reader.iter_messages` is a single pass over the tlog; + pymavlink's `recv_match(blocking=False)` is the standard idiom. +* `ap_contract_evaluator` consumes the materialised list ONCE per + analyser; `collect_messages_to_list` is the documented choice + (mavlink_connection's iterator closes on exhaustion so re-iteration + isn't safe). For typical 60 s of mavproxy traffic at ~50 msg/s this + is ≤3000 messages → trivial in memory. +* `cold_start_evaluator._scan_fdr_for_cold_start` is one pass. +* No nested loops over the same data. + +### Phase 6 — Cross-Task Consistency + +* **Pattern parity with batches 69 + 70 + 71**: + - Skip gate (`_*_harness_implemented` fixture) for missing upstream + replay/SITL/FDR helpers — same pattern as + `test_ft_p_02/04/05/07/08/10_*`. + - `_NullSink` probe — same idiom as the prior 5 scenario files. + - Evidence side-channel via `nfr_recorder.record_metric(name, value, + ac_id=…)` — same pattern as `test_ft_p_01/04/05/07/08/10_*`. + - Module-level constants (`UPPER_SNAKE`) for budgets — matches + `multi_segment_evaluator`, `mre_evaluator`, `smoothing_evaluator`, + `sharp_turn_detector`. + - Helper modules importable from `runner.helpers.*`. +* **No drift**: scenarios reuse the helper's constants (no magic + numbers) — `HANDSHAKE_BUDGET_S`, `GPS_INPUT_MIN_RATE_HZ`, + `MIN_FIX_TYPE`, `ACCURACY_BUDGET_M`, `BOUNDED_DELTA_TRIGGER_M`, + `FDR_RECORD_*`, `FORBIDDEN_FIRST_LABEL_BOUNDED_DELTA`. +* **No legacy NotImplementedError test left behind**: verified no test + asserts `iter_messages` raises NotImplementedError (was AZ-406's + surface contract; AZ-416 owns the body per docstring). + +### Phase 7 — Architecture Compliance + +* **Public-boundary discipline**: confirmed by `test_no_sut_imports.py` + (passing). Helpers consume pymavlink (a third-party MAVLink + reference impl, not SUT internals) + FDR record schema (record_type + + payload dict) + outbound estimate schema. The signing handshake + observer specifically does NOT import the SUT's signing-key state + per the spec "Forbidden" list. +* **Directory layout**: new paths added to `test_directory_layout.py` + parametrize list (`runner/helpers/{msp_frame_observer, + ap_contract_evaluator, cold_start_evaluator}.py`, + `tests/positive/test_ft_p_{09_ap_signing, 09_inav, 11_cold_start_init}.py`). + All variants pass. +* **Determinism**: all helpers are deterministic — no `time.time()`, + no RNG; pymavlink parses bytes deterministically. + +### Phase 8 — Test Suite Health + +* Total: **460 passed in 134.35 s** (was 393 at end of batch 71). +* New tests this batch: **+67** (msp_frame_observer: 14; + mavproxy_tlog_reader: 6; ap_contract_evaluator: 22; + cold_start_evaluator: 19; directory_layout new entries: 6). +* Pre-existing macOS-only `/e2e-results` plugin issue still present — + affects scenario test invocation outside Docker only; unit suite + unaffected. Out of batch scope. + +## Cross-Task Consistency Verdict + +PASS — no cross-task drift, no duplicated logic across the four new +helpers, shared `TlogMessage` type used consistently between +`mavproxy_tlog_reader` and `ap_contract_evaluator`. + +## Architecture Compliance Verdict + +PASS — public-boundary blackbox stance preserved; no SUT imports; +pymavlink boundary correctly placed at the tlog reader. + +## Final Verdict + +**PASS** — Batch 72 (AZ-416 + AZ-417 + AZ-419) ready for commit. diff --git a/_docs/_autodev_state.md b/_docs/_autodev_state.md index e95b63b..4cce34e 100644 --- a/_docs/_autodev_state.md +++ b/_docs/_autodev_state.md @@ -12,8 +12,8 @@ sub_step: retry_count: 0 cycle: 1 tracker: jira -last_completed_batch: 71 -last_cumulative_review: batches_67-69 +last_completed_batch: 72 +last_cumulative_review: batches_70-72 last_step_outcomes: step_8: "Code is testable — no changes needed (testability_assessment.md committed; no list-of-changes, no source edits)" step_9: "Already complete — 41 blackbox test tasks (AZ-406..AZ-446) under epic AZ-262 with specs in _docs/02_tasks/todo/ were produced in a prior cycle; AZ-406 test-infrastructure bootstrap also pre-existing.
