 `ChatService` communicates with Reddit's Matrix homeserver, maintains an account-scoped SQLite-backed cache, resolves `t2_` identities to Reddit usernames, and emits sync progress/new-reply callbacks. Startup chooses full or delta sync from persisted cursor state. Operators can explicitly run tracked sync jobs through the versioned API.
 
-`MediaService` resolves Matrix media, downloads it into the persistent data directory, and writes an account-scoped media index. `MediaSyncService` schedules incremental work only while the account is authenticated. The media listing exposes received items only: records attributed to the owning Reddit/Matrix account are excluded, including historical self-sender forms. Private media is served behind the same authorization boundary as the dashboard and APIs.

The media listing reads persisted indexes for every stored account, including accounts whose runtimes are stopped or require login, and exposes received items only: records attributed to the owning Reddit/Matrix account are excluded, including historical self-sender forms. Private media is served behind the same authorization boundary as the dashboard and APIs.
 
 The process-global exchange library is separate. Dashboard uploads are decoded and re-encoded with `sharp`, which validates the actual JPEG/PNG/WebP contents, applies orientation, and removes EXIF/location/camera metadata. OpenRouter then assigns overlapping anatomy tags plus SFW/NSFW classification. Failed or low-confidence classifications remain disabled until the operator corrects them.
