Two live-test findings on the images load path:
- transformer_quant with baked LoRAs, when the dense quantized build is
declined for memory or fails: the load completed as a plain GGUF with the
adapters silently dropped (HTTP success, supports_lora=false after the
fact) -- wrong output with no signal. The load now fails with the recovery
options (drop the adapters, free VRAM, or pick a smaller model). Weight-0
adapters still count as no bake request, and the plain no-LoRA decline
keeps its silent GGUF fallback.
- A fresh GGUF load on a small GPU prefetched the base repo's full bf16
transformer shards (~47 GB on Qwen-Image) because the dense-quant prefetch
widening only checked scheme viability, not whether the device could ever
hold the candidate resident. Gate the widening on total device capacity
(reserve + 0.85 margin, the plan_fits_total_capacity bar) so a card that is
certain to decline the dense build never pays the download; capable devices
keep the prefetch.
