- modeld standby: skip inference at standstill (model stays loaded in GPU), ModelStandby param + ModelStandbyTs heartbeat for race-free suppression - controlsd: suppress commIssue/modeldLagging when ModelStandbyTs < 2s old, ignore telemetryd/dashcamd in process_not_running check - Fan controller: standstill below 74°C clamps to 0-10% (near silent), standstill above 74°C allows 0-100%, thermald reads carState.standstill - Deleter: enforce 4GB quota on /data/log2 session logs, oldest-first cleanup - Diagnostic logging: steerTempUnavailable and controlsdLagging log to stderr with full context (steering angle, torque, speed, remaining time) - CLAUDE.md: document memory params method name difference (C++ camelCase vs Python snake_case) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
