Comprehensive diagnostic logging: Every silent decision point in the bootstrap, device connect, data download, theme load, overlay config, and LED send paths now has a log line. Multi-device issues are now diagnosable from ~/.trcc/trcc.log alone.
Pre-existing test warnings: _wire_device() now guards against settings=None — eliminates AttributeError in integration test threads.
ensure_all() silently swallowed exceptions: Individual ensure_*() failures now caught and logged per-step instead of crashing the entire data download.
Overlay config parse errors swallowed: load_overlay_config_from_dir() now logs parse errors instead of except: pass.
LED send_led_data() failures swallowed: Exception now logged instead of returning False silently.
