+The endpoint intentionally does not infer candidate scoring history. Selected candidate metadata is persisted when Spooty chooses a candidate. Rejected candidate metadata is persisted when a selected candidate is rejected by manual retry or download failure. Older rows and URL-only cases fall back to rejected candidate objects containing only `url`.
 
 Future persistence work is required for:
 
 - full searched candidate history
-- structured rejected candidate metadata beyond URL
 - structured error class fields stored at write time instead of classified from the persisted raw error string
 - operation attempt history across search and download phases
