Any artifact can now be made publicly viewable via a share link, no login
required - opt-in per artifact, toggled from the feed UI next to Keep.
- Artifact.share_token: nullable, unique, high-entropy (secrets.token_urlsafe(32)).
NULL = not shared; SQL treats each NULL as distinct so uniqueness still
holds for the many not-shared rows.
- New public route GET /s/<token> (shared_artifact_view), completely
unauthenticated, serving the same rendered/raw content as the owner
route via a shared serve_artifact_file() helper.
- toggle_artifact_share: generates/clears the token: mirrors
toggle_artifact_keep's pattern.
- Fixed a real gap this surfaced: embedded images in a shared artifact's
content would otherwise break for an anonymous visitor, since asset_view
was owner-only. It now also allows access when the asset's parent
artifact is currently shared - unattached (orphaned) assets stay private
regardless.
- serialize_artifact now reports is_shared/share_url so the API reflects
sharing status (read-only for now; toggling stays UI-only).
- Feed UI: Share button (mirrors Keep's toggle interaction), a copyable
share-link box that appears when shared, and a "shared" badge on the
artifact row - distinct blue accent from Keep's green so both can be
visible on the same row without confusion.
Verified live end-to-end (toggle on/off, public access, fake-token 404,
old-link-dies-on-unshare, embedded-asset access before/after sharing)
before writing the 12 automated tests in tests/views/test_sharing.py.
Also fixed two unrelated stale spots noticed in docs/api.md while adding
the Sharing section: the example response was missing is_kept/size_bytes,
and the raw-content table didn't list json/csv (added earlier this
session but never documented there).
