The edit (pencil) action now edits a download's full display metadata — title,
channel name, channel link and any number of extra reference URLs — instead of
just the name. The channel and links render as clickable links on the library
card, and the channel link is auto-filled from the source (yt-dlp channel_url)
when available. Shared watch pages resolve the same per-download overrides, so a
rename/channel/link edit is reflected on the public /watch page too, with every
link clickable.
Adds migration 0049 (media_assets.uploader_url; download_jobs.display_uploader,
display_uploader_url, extra_links) and generalizes the rename endpoint into a
metadata update with URL validation. EN/HU/DE strings included.
Share a download by a capability URL (/watch/{token}) that anyone can play on a login-free page —
distinct from the registered-user ACL share. Per-link controls: optional expiry, allow-download
toggle (stream-only vs downloadable), optional argon2 password. Revoke = delete.
- migration 0042 + DownloadLink model; app/downloads/links.py (token, HMAC grant sign/verify)
- owner endpoints (POST/GET/PATCH/DELETE links) + /recipients for the internal user picker
- public router (no auth): watch meta / password unlock→signed grant / range-aware file serve
(inline vs attachment); unlock is rate-limited; meta verifies the file exists on disk
Verified end-to-end: 206 range, inline vs attachment, wrong-password 403, tampered-grant 403.
