FuguCTX

FuguCTX is a configuration repair model for OpenBSD daemons. FuguCTX reads a broken daemon configuration and a parser error, and it proposes the smallest fix as a unified diff. The operator reads the diff and decides.

The engine is a Qwen3-1.7B fine-tune under llama.cpp, on the CPU only. The ctx tool writes a diff to standard output, and it must not change a system.

The project is the pilot of FuguTTX. The build rehearses the FuguTTX production pipeline at small scale, on the same components, at real prices. OpenBSD supplies a deterministic judge for every configuration: the parser of the daemon.
