setup-ai-studio.sh's director download honored MODEL_DIR, but the ComfyUI
assets (image/video/audio) defaulted to a hardcoded /mnt/models/comfyui — so
any rig whose models don't live under /mnt failed mid-download with
"mkdir: Permission denied" (sumo Discord report, 2026-06-27). Two more walls
behind it: the disk-space preflight checked the hardcoded /mnt path and had no
override (an idempotent resume under-threshold was blocked), and gpu-mode.sh —
which setup calls at step 3 — hardcoded CLUB3090_DIR=/opt/ai/github/club-3090,
breaking on any other clone.
- New services/comfyui/comfyui-paths.sh: derive COMFYUI_ROOT / COMFYUI_MODELS_DIR
as a "comfyui" sibling of MODEL_DIR (read from repo-root .env when unset).
Backward-compatible on the rig (/mnt/models/huggingface -> /mnt/models/comfyui);
explicit overrides respected. Sourced by setup-ai-studio.sh,
download_studio_models.sh, and gpu-mode.sh so the download target, the disk
check, and the container mounts all agree.
- setup-ai-studio.sh: disk check uses the derived path; add SKIP_DISK_CHECK=1 to
bypass the free-space preflight independently of SKIP_DOWNLOAD.
- gpu-mode.sh: auto-detect CLUB3090_DIR from the script's real location (resolving
the /usr/local/bin symlink), overridable via env — removes the hardcoded path.
- The 3 legacy hardcoded download scripts (flux2/hunyuan_llava/models) honor
COMFYUI_MODELS_DIR.
- New test-comfyui-paths.sh guards the derivation; docs/ai-studio config note.
Full suite green (59/59).
