John O'Keefe 4a6fb033cb docs(media-items): Work Order 3 batch 3b — management endpoints (8)
New frontmatter'd docs:
- download (ServeFile — raw bytes, family-lens enforced; corrects the old
  download doc's claim that no download route is registered: ServeFile IS
  routed, DownloadBook is the dead code)
- set_audio_speed (speed range 0.25-4.0, NaN/Inf rejected)
- rescan (abridged example over the full 70+-column row; write-after-success
  guarantee noted)
- purge-archived (destructive, admin), unarchive (204), merge (SHA-256
  precondition, per-user collisions keep active copy)
- facets (two modes: facet+values, field autocomplete counts)
- filter_count (family lens)

Registry: RawMessage pins for map/abridged responses; Schema{} for non-JSON
body routes (download = raw bytes; unarchive = 204). Audit now:
missing docs down to ~55 (from 112), 0 orphans.

GET /api/media-items/facets jwt media-items

Get Media Item Facets

Two modes, both returning small JSON objects:

  1. Facet values (primary): ?facet=<param>&library_id=<uuid> — lists the distinct values of a facet within one visible library.
  2. Autocomplete counts: ?field=<key>&library_id=<uuid> — returns {"facets": {...}} value counts for dropdowns.

Example response

{
  "facet": "author",
  "values": [
    {
      "value": "George Orwell"
    }
  ]
}

UNVERIFIED: exact element shape of values (service-returned rows).

Query parameters

Param Type Notes
facet string facet param name; requires library_id
field string registry field key (autocomplete mode)
library_id uuid required for facet mode; must be visible to the requester
limit number caps facet values
