Client reported crashes, wrong/frozen data and that the app floods the adapter MCU. See docs/FIX_2026-10-12.md for the full analysis. - Poller: strictly one request outstanding; next request only after a valid 128-byte reply or a 500 ms timeout, then a quiet period + buffer flush. Default 100 ms (10 Hz), minimum 80 ms. DTC clear/probe share the same lock. - BtNotifier: filter the adapter's default (no-ECU-data) frame instead of holding last values; EcuDataStatus + status banner; auto-reconnect on link loss, stalls or long default-only runs (rate-limited). A reconnect still in flight when the user disconnects is discarded. - S300 offsets corrected by column counting (trims, PA, ERR00-03, Eth, SW5, AF); INJ/AIN little-endian; fan = SW5 FANC only. Default-frame detection requires bytes 0-16 and 32-36. - KPro RPM/MAP2/AIN little-endian (RPM still needs a bench check). - Crash hardening: zone/Flutter/platform error handlers to an in-app log (copyable from Debug); permissions requested before listing devices. - Remove temporary debug prints; graph redraws live; polling options 100-300 ms, persisted.
