From bb744d90783b8eb6b06f7250b460ba9c9e887398 Mon Sep 17 00:00:00 2001 From: Oleksandr Bezdieniezhnykh Date: Sun, 17 May 2026 14:46:08 +0300 Subject: [PATCH] [AZ-420] Batch 81: FT-P-12 + FT-P-13 GCS scenarios FT-P-12: parse mavproxy-listener tlog over a 60 s Derkachi replay and assert SUT->GCS GLOBAL_POSITION_INT cadence lands in [1, 2] Hz (AC-6.1). FT-P-13: inject `RELOC:,,` STATUSTEXT while the SUT is in dead_reckoned; verify FDR `c8.gcs.operator_command` ack <=2s, `anchor_search_region` centre shifts toward the hint, and no BAD_SIGNATURE / UNAUTHORIZED / REJECTED STATUSTEXT lands in the post-inject window (AC-6.2). Adds runner.helpers.gcs_telemetry_evaluator (rate, hint-ack correlation, haversine search-region shift, rejection scan) and sitl_observer.capture_gcs_tlog (parity surface to capture_ap_tlog). Pure-logic coverage: 39 new unit tests; full e2e/_unit_tests/ suite 746 passing (was 700). Scenarios skip locally on missing SITL replay fixture; production hooks (inbound STATUSTEXT parser, anchor_search_region FDR emitter) tracked outside this task.

Leaving the conservative semantic in + place — "no hints" is a misuse of the correlator, not a trivial + pass — and pushing the explicit failure upstream where the + contextual error message ("the fixture builder must inject at + least one operator re-loc hint") is more useful. +* **AC-3's `passes` is non-strict shift.** A region exactly + equidistant before/after the inject is treated as "not biased" + (`distance_after_m < distance_before_m` is strict). This matches + the spec wording "shifts toward the hinted location" — zero + movement is not a shift. Documented in + `SearchRegionShiftReport.passes`. +* **Counted `GLOBAL_POSITION_INT` only for AC-6.1, not the + `NAMED_VALUE_FLOAT` companion.** The QGC adapter pairs them so + counting both would double-count. The position message is the + contract-relevant half; the NAMED_VALUE_FLOAT carries the decorative + horizontal-uncertainty annotation. +* **Tests are shaped to fail loudly when the upstream production + hooks are missing.** AC-2 requires the C8 adapter to translate an + inbound STATUSTEXT into an FDR `c8.gcs.operator_command` record; + AC-3 requires the C2 backbone to emit `anchor_search_region` FDR + records. Both are deferred work outside AZ-420's scope. The + scenario tests skip cleanly when no fixture is present + (`sitl_replay_ready=False`) and fail with a specific error when + the fixture exists but lacks the expected hint or ack records. + This is the "tests as gates" pattern called out in the implement + skill. + +## Production Dependencies (forward-look) + +FT-P-13 transitively depends on: + +* **Inbound STATUSTEXT command parser** in + `c8_fc_adapter/mavlink_gcs_adapter.py`. Currently the adapter emits + but does not consume STATUSTEXT. The C12 + `MavlinkOperatorCommandTransport` concrete impl is a Protocol-only + stub. +* **`anchor_search_region` FDR record** emitted by the C2 backbone + per nav-camera frame. The FDR schema (AC-NEW-3 family) reserves + the slot but no producer wires it. + +These gaps are surfaced (not silently absorbed) by the scenario +tests when the fixture builder produces a tlog without the +corresponding fixtures. They will be picked up by future production +implementation tasks; AZ-420 owns the test surface only. + +## Out of Scope (deferred) + +* Spoofed-GPS escalation STATUSTEXT path — owned by FT-N-04 (AZ-426). +* Operator-reloc-request emission negative-path — owned by FT-N-03 + (AZ-425). +* The fixture builder's actual `gcs_tlog_.tlog` synthesis (with + `RELOC:` injection + corresponding FDR `c8.gcs.operator_command` + ack + `anchor_search_region` records) — owned by AZ-595. + +## Next Batch + +Batch 82 candidates from `_docs/02_tasks/todo/` (21 tasks remaining): +AZ-421 (FT-P-14), AZ-422 (FT-P-15), AZ-423 (FT-N-01), AZ-424 +(FT-N-02).
