 - [x] #198 (upstream #3581) — "import files" task shows source storage policy "unknown": `ImportTaskState.PolicyName` baked at creation (resolved best-effort via `StoragePolicyClient`), summary emits `dst_policy_name` so admin views of other users' tasks work without a policy lookup; `policyOptionCache` retyped to `StoragePolicyBrief[]` and populated from `getAllowedPolicies()` at session init as fallback for legacy tasks
 - [x] #199 (upstream #3584) — markdown editor lag: root cause was per-keystroke React re-renders (changedValue state fed back into the editor's initial-markdown prop) re-running every plugin's `update()` hook (RealmWithPlugins has a dep-less effect). `MarkdownEditor` is now `memo`'d with a `useMemo`'d plugins array + stable `translation`; `MarkdownViewer` keeps edits in a ref (read at save) and passes the immutable loaded content — zero re-renders per keystroke
 - [ ] #200 (upstream #3586) — Pro crash on SIGHUP; log shows a clean signal-driven shutdown, no stack trace — watch for a CE repro, likely not actionable yet
+- [x] #89 (upstream #3277) — Android Motion Photo preview: `util/motionPhoto.ts` extracts the MP4 appended at EOF of MicroVideo/MotionPhoto JPEGs — XMP `GCamera:MicroVideoOffset` or `Container:Directory` `video/mp4` `Item:Length`, fetched via Range requests (128 KiB head + video tail only), `ftyp` sanity-checked; `Photo.tsx` feeds the blob URL into the same LivePhotosKit player used for iOS live photos — badge + press-to-play for free; degrades silently on CORS/fetch failure
 - [x] `desloppify` pass — 73 review items dispositioned (46 fixed, 27 honestly skipped), strict score 77.1 (was 18.9); scorecard lives in README. `security-reviewer` pass done incrementally per batch (OAuth secrets, SSRF, process exec, path safety)
 - [x] Tag management page (upstream #2962) — owner-scoped `tag:` metadata stats/rename/recolor/delete in `inventory.FileClient`, `GET/PATCH/DELETE /file/tag` routes, Settings → Tags tab with merge-on-rename semantics
 - [x] Download URL shuffling (#173) — `download_cdn_shuffle` distributes generated download URLs randomly across the site URL + `download_cdn_routes` endpoints (`setting.DownloadURLBase`, honors `UseFirstSiteUrl`); covers entity downloads, archive sessions, and redirect-type direct links; manual route picker hidden client-side while active
