Per-photo raw results cached under data/extract_raw/ (gitignored) so
re-runs are free, --only re-extracts a single photo, and titles.json is
rebuilt with dedupe that keeps conflicting-edition sightings separate.
HEIC converts via pillow-heif; images downscale to <=1568px long edge;
model JSON parsed defensively (code fences, surrounding prose). Vision
callable is injectable — tests use a local fake; the real one uses the
anthropic SDK (approved) with the model from config.toml.
