Replace ~25 panic() calls in non-fatal code paths with proper s.logger.Error + return patterns. Panics in handler code crashed goroutines (caught by defer/recover but still disruptive) instead of failing gracefully. Key changes: - SJISToUTF8 now returns (string, error); all 30+ callers updated - Handler DB/IO panics replaced with log + return/ack fail - Unhandled switch-case panics replaced with logger.Error - Sign server Accept() panic replaced with log + continue - Dead unreachable panic in guild_model.go removed - deltacomp patch error logs and returns partial data Panics intentionally kept: ByteFrame sentinel, unimplemented packet stubs, os.Exit in main.go.
Verified via Wii U decompilation of putUpdate_house: the field is set to 0 when no password is provided, and 1 when a password string is present. The previous comment "Always 0x01" was inaccurate.
