Fetcher (the two remaining bugs Codex found):
- Real redirects are now followed. _NoRedirect makes urllib RAISE HTTPError on 3xx, so
the old status-branch was dead code (mocked tests masked it). Handle 301/302/303/307/308
HTTPError as redirects (re-validate the destination); classify 4xx≠429 as PERMANENT
(negative-cached), 429/5xx/network as transient. Real-opener redirect + 404/5xx tests.
- The megapixel ceiling is now enforced: explicit `w*h > _MAX_PIXELS` check BEFORE load()
(Pillow only warns at MAX_IMAGE_PIXELS). Test with a lowered ceiling.
Image-rights policy (per Codex + owner decision — only cache what's cleared):
- sources.image_policy: 'cache' (re-host a downscaled copy — license/permission/PD only),
'remote' (hotlink the publisher's image — the conservative DEFAULT), 'none' (no image).
- newsimg.display_url resolves the display URL per policy; applied in Article.from_row so
feed/brief/history return the right URL, and in share.py (og/twitter still reference the
publisher's own image, never re-hosted). warm() + /api/img both gated on 'cache'.
- Frontend uses the server-resolved image_url (reverted the hardcoded /api/img); the
graceful retry covers remote hotlinks too. Admin: per-source image-policy selector +
POST /api/admin/sources/{id}/image-policy. Default 'remote' → nothing re-hosted until
a source is explicitly cleared.
445 backend + 36 frontend tests pass.
