immich-ml at TTL=0 never unloaded models; a heavy OCR library job
inflated onnxruntime's CUDA arena to ~10.7GB and held it on the shared
time-sliced T4, starving llama-swap (qwen3-8b) so recruiter-responder
triage 502'd silently for hours (emails preserved unseen, no loss).
TTL=600 lets idle ad-hoc models (OCR, face) free VRAM while preloaded
CLIP/smart-search stays warm.
Docs: correct stale llama-cpp GPU notes (T4 is time-sliced, no VRAM
isolation; add qwen3-8b to model table), immich MODEL_TTL gotcha in
.claude/CLAUDE.md, and a post-mortem.
