From 17dd2e02bab4d00a93479eb6af1a8c6ddc0c7224 Mon Sep 17 00:00:00 2001 From: "alexei.dolgolyov" Date: Tue, 9 Jun 2026 16:35:08 +0300 Subject: [PATCH 01/13] fix: resolve comprehensive review findings (security, concurrency, perf, Android, UI) Multi-dimension review of v0.8.2. Excludes the deliberately deferred default_config.yaml weak-default-key item (C1). Backend: - calibration: create_default_calibration no longer exceeds led_count for small odd counts (bounded trim + regression test) - game-integration: generic webhook now requires auth_token; constant-time compare_digest in all adapters; per-IP failed-auth rate limit on the ingest route; auth_token encrypted at rest via secret_box (migration-safe) - playlist engine: serialize _state/_task under the lifecycle lock to close a delete-mid-play race (+ concurrency tests) - main: stop the calibration session on shutdown (restore prior target) - home_assistant: validate HA host via the LAN classifier on create/update - perf: drop slow preview-WS clients instead of blocking the send loop; cache composite full-strip resize linspaces; effect_stream lava reuses scratch Frontend: - setup/auto-calibration wizard: guard _state after awaits (cancel-safe), await session teardown before output start, busy-gate skip-calibration, manual display input keeps focus, move focus on step change - calibration: destroy EntitySelect on modal close - color-strips test: dirty-flag-gated render + cached ctx/ImageData - a11y/TV: focus-visible for new wizard/auto-cal/corner controls, aria-labels on the spatial corner/edge picker; theme-aware syntax tokens; dead/undefined CSS tokens removed; .modal-error styled; i18n titles (en/ru/zh) Android: - ApiKeyManager: EncryptedSharedPreferences with verified, data-safe legacy migration that never rotates an existing key - CaptureService: validate MediaProjection token before promoting; satisfy the startForeground 5s contract on the bail path - NotificationListener: connection-scoped executor with lazy fallback - BLE: request BLUETOOTH_SCAN/CONNECT at runtime + guard handler-thread SecurityExceptions - Root: cancellation-aware su grant probe Adds 14 tests.

Ruff clean. +Phase 3 landed (2026-06-09): instrumented all four categories — entity CRUD via `fire_entity_event` choke-point (`dependencies.py`), auth failures + WS session in `auth.py`, device online/offline in `device_health.py`, device discovered/lost in `discovery_watcher.py`, ADB connect/disconnect in `system_settings.py`, capture start/stop (individual + bulk) in `output_targets_control.py`, scene/playlist/automation activate in their respective route/engine files, backup/restore/delete + restart/shutdown/update/calibration/settings in `backup.py`/`update.py`/`calibration.py`; all 11 entity delete handlers pass `entity_name` to `fire_entity_event`; 22 new tests (security: token never in any field, explicitly asserted) — all green. Full suite 2369 passed, 2 skipped, 0 failed. Ruff clean.
