fix: define _ip helper (verify 500)

merge: in-process ZTC (CPU, 4B) in single Docker space; drop second space

auth ZTC calls via HF_TOKEN env (bigger ZeroGPU quota)

fix gradio_client Client() hf_token kwarg compat

KNOU as Docker UI (3D ontology graph + LLM); /verify -> FINAL-Bench/KNOU-ZTC (ZeroGPU)

fix ZeroGPU detection: register @spaces.GPU ztc_score as gradio event

fix ZeroGPU: literal @spaces.GPU decorator (startup detection)

KNOU moved to FINAL-Bench: ontology graph + in-process ZTC verify on ZeroGPU
