From 78dcf7b4e74739692695cb8d0b70f6ea91fc1e0e Mon Sep 17 00:00:00 2001 From: Yuzviak Date: Thu, 2 Apr 2026 18:27:35 +0300 Subject: [PATCH] =?UTF-8?q?fix:=20post-audit=20=E2=80=94=20runtime=20bugs,?= =?UTF-8?q?=20functional=20gaps,=20docs,=20hardening?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase A — Runtime bugs: - SSE: add push_event() method to SSEEventStreamer (was missing, masked by mocks) - MAVLink: satellites_visible=10 (was 0, triggers ArduPilot failsafe) - MAVLink: horiz_accuracy=sqrt(P[0,0]+P[1,1]) per spec (was sqrt(avg)) - MAVLink: MEDIUM confidence → fix_type=3 per solution.md (was 2) Phase B — Functional gaps: - handle_user_fix() injects operator GPS into ESKF with noise=500m - app.py uses create_vo_backend() factory (was hardcoded SequentialVO) - ESKF: Mahalanobis gating on satellite updates (rejects outliers >5σ) - ESKF: public accessors (position, quaternion, covariance, last_timestamp) - Processor: no more private ESKF field access Phase C — Documentation: - README: correct API endpoints, CLI command, 40+ env vars documented - Dockerfile: ENV prefixes match pydantic-settings (DB_, SATELLITE_, MAVLINK_) - tech_stack.md marked ARCHIVED (contradicts solution.md) Phase D — Hardening: - JWT auth middleware (AUTH_ENABLED=false default, verify_token on /flights) - TLS config env vars (AUTH_SSL_CERTFILE, AUTH_SSL_KEYFILE) - SHA-256 tile manifest verification in SatelliteDataManager - AuthConfig, ESKFSettings, MAVLinkConfig, SatelliteConfig in config.py Also: conftest.py shared fixtures, download_tiles.py, convert_to_trt.py scripts, config wiring into app.py lifespan, config-driven ESKF, calculate_precise_angle fix. Tests: 196 passed / 8 skipped. Ruff clean.
