- SIGSEGV/SIGABRT crash handler in ui/main.cc prints stack trace to stderr - Fixed onroad crash: guard update_model() against empty model position data (was dereferencing end()-1 on empty list when modeld not running in bench) - Status window: added device temperature and fan speed - Interactive timeout returns to splash/onroad (not ClearPilotPanel) - bench_cmd dump detects crash loops via UI process uptime check - bench_cmd wait_ready timeout increased to 20s - Restored camerad to bench ignore list (not needed for UI testing) - Updated CLAUDE.md with crash debugging procedures Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
