Houmgaor	f640cfee27	fix: log SJIS decoding errors instead of silently discarding them ... Add SJISToUTF8Lossy() that wraps SJISToUTF8() and logs decode errors at slog.Debug level. Replace all 31 call sites across 17 files that previously discarded the error with `_, _ =`. This makes garbled text from malformed SJIS client data debuggable without adding noise at default log levels.	2026-02-22 17:01:22 +01:00
Houmgaor	d32e77efba	refactor: replace panic calls with structured error handling ... 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.	2026-02-20 19:11:41 +01:00
Houmgaor	0e84377e21	feat(protbot): add headless MHF protocol bot as cmd/protbot ... Copy MHBridge into the Erupe module as cmd/protbot/ so it can be built, tested, and maintained alongside the server. The bot implements the full sign → entrance → channel login flow and supports lobby entry, chat, session setup, and quest enumeration. The conn/ package keeps its own Blowfish crypto primitives to avoid importing erupe-ce/config (which requires a config file at init).	2026-02-20 02:49:23 +01:00
