What caused the Rust crash in govee2mqtt?

Govee's API switched preset names to Chinese characters (3-byte UTF-8), hit by byte-indexed slicing in camel_case_to_space_separated(). Whole bridge panicked.

Can non-developers fix open source bugs?

Absolutely — triage issues, clarify threads, suggest fixes via AI. Coding optional; pattern-spotting mandatory.

Is govee2mqtt safe after the fix?

Yes, .chars() handles multi-byte strings. Monitor Govee APIs though — changes incoming.
