Messages were in-memory only — gone on leaving the conversation. - MessageStore: keystore-backed (no plaintext), a capped per-peer JSON list (last 200). Simple; the encrypted Drift DB is the eventual home at scale. - MessagesCubit: loads saved history on start (subscribes FIRST, then loads, so a message arriving during the load isn't dropped) and persists every sent and received message. Wired via DI + TaneApp(messageStore). Tests (plain 'test', no hang risk): MessageStore round-trip/per-peer/cap, and a cubit test that reopens a fresh cubit and sees the saved conversation. Analyzer clean; run 'flutter test' locally to confirm.
