Closes the last acquisition gap — user-initiated downloads. A blocklist isn't
a censor, so search + discography stay fully visible; instead the download
ACTION is gated, visibly and overridably:
- Download modal (start-missing-process): an up-front check — if the WHOLE
album or artist being downloaded is blocklisted, return 409 {blocked:true}
with the entity, before starting a batch. The modal shows "X is blocklisted
— download anyway?" and re-POSTs with ignore_blocklist:true on confirm
(threaded onto the batch so the Phase 2a per-track filter skips it).
Scattered single-track bans still fall through to the 2a filter quietly.
- Manual /api/download (search-result download): source-file-centric, so it
matches the blocked ARTIST by name; same 409 + confirm + override. search.js
now sends artist/title so the guard has something to match.
- Precedence confirmed: force-download overrides "already owned", NOT a ban
(the 2a filter runs on the force-expanded missing list).
Frontend: shared confirmBlockedDownload() helper; modal + search callers
handle the blocked response and retry with the override.
Tests: manual download blocked-by-name / unrelated-allowed / override-passes,
and the modal up-front 409 for a blocked album. 8 blocklist API tests pass.
