Безопасность: - Rate-limit на /api/voice/chat (20/мин per cookie/IP, env VOICE_RATE_LIMIT). Защищает от случайных циклов и утечки PIN. - Усечение user prompt'а до 4000 символов в /api/voice/chat. - Tool-loop защита от циклов: если LLM дважды просит тот же tool с теми же args — прерываем (раньше мог уйти в бесконечный цикл при tool error'ах). Чистка кода: - lib/debug.ts — vlog/vwarn/verror гейтят браузерные логи за NEXT_PUBLIC_VOICE_DEBUG=1 (или localStorage 'voice-debug=1'). Серверные console.log оставлены — полезны в Docker logs. - lib/audio-wav.ts — вынесена дублированная floatToWav из VoiceController. - Удалены orphan компоненты FocusCard.tsx и CountdownCard.tsx (не подключены, отвергнуты по UX-фидбеку). Resilience: - WakeWordDetector: drop-on-busy в onChunk — на медленных устройствах (Android, бюджетный CPU) backlog inference больше не копится. - voice-history fallback на /tmp/voice-history если /data не примонтирован (локальная разработка / нестандартная конфигурация).
