- PROTOCOL.md: полная спецификация (KDF, envelope/CBC-цепочка, local_reg, key exchange, commands.json 206/200, datapoint push, тайминги, таблицы свойств шаблонов A/B/F, облачный provisioning). Факты из APK помечены [APK], проверенные живыми экспериментами на AP-WC1E — [ПРОВЕРЕНО НА ПРИБОРЕ]: mDNS только :10276; лимит 2 LAN-сессии (3-я -> 503); принудительный re-key при возрасте сессии >= ~44с (единственный механизм самолечения десинхрона — 400/401 модуль игнорирует); записи не эхируются; delete_session освобождает слот. - LEGACY_ANALYSIS.md: причины рассинхрона (keep-alive 1200с вместо 10-15с + seq_no-фильтр) и перегрузки модуля; требования к новой реализации. - PLAN_CORE_LIBRARY.md: план C++20-библиотеки fglair-core (Linux + ESP-IDF), ключ lanip_key считается статичным, ротация — только ошибка + ручной перепровижининг. - PLAN_HOME_ASSISTANT.md: pyfglair (cffi wheel) + custom component, облачный provisioning только в config flow, ключ виден в диагностике для копирования в ESPHome. - PLAN_ESPHOME.md: external component, только ESP-IDF framework. - tools/probe_reference.py: эталонный клиент протокола (проверен на приборе end-to-end); tools/probe_mdns.py — mDNS-проба. - legacy/: снимок скрипта (апстрим gyro-labs/AirCon, вложенный клон не версионируется); apk/*.apk исключены из версионирования.
