   - [x] C11 preview caching: Discord-hosted image/GIF previews (WebP 320px, hash-addressed, 5 MiB
     cap, one attempt) run after every walk in both modes. Live run `...-20260916090722`:
     `previewed: 2`; thumbs served over `/api/media/<scrape>/<item>/thumb` (200).
+  - [x] C37 Advanced search drawer, adaptive paging, and zoom. Filters moved into an **Advanced
+    search** drawer with Apply/Reset (no auto-update): filetype chips, source kind, origin

+    **cachedOnly**). A **Card size** slider scales tiles from 100 px (2/3 of current) to one image
+    per row; page size = full rows about 1.5 screens tall and follows zoom/resize. Infinite scroll
+    preloads the next page's JSON and previews. Backend gained `authorIds`, `origin`, `cachedOnly`
+    on `/api/media`, `/api/media/stats`, and MCP `query_media`. Verified: `origin=dm` and
+    `cachedOnly=1` return the expected rows.
   - [x] C36 Daemon restart, preview diagnostics, browse-time caching, and rate-limit pauses.
     Settings → Server has a **Restart daemon** button (`POST /api/daemon/restart`: re-execs the
     daemon, keeps the client running). The preview pass logs every failure with scrape/item/kind/
