 5. Output: `tui/` renders interactively, or `output.rs` emits JSON/NDJSON
 
 ### Key type: `MediaEntry` (in `types.rs`)
 
-The central data type. Every module reads or produces it. It serializes to the JSON schema (version `0.1.0`). If you change `MediaEntry`, you affect JSON output, TUI rendering, filter evaluation, and sort comparison. `MediaKind` includes a `Image` variant. `MediaInfo` has an optional `exif: Option<ExifInfo>` field populated for image files.

 ### Output format
 
-JSON output uses borrowing structs (`ListEnvelopeRef<'a>`, `NdjsonEntryRef<'a>`) to avoid cloning `MediaEntry` vectors. Schema version `"0.1.0"` is embedded in output.

 - `triage.rs` Move (`m` key) works via text input; interactive directory picker not yet built.
 - `scan.rs` uses bounded `JoinSet` spawns (not a semaphore) for concurrency control, with `mpsc` channel for streaming results to the caller.
 - Images are loaded directly in `thumbnail.rs` (bypass ffmpeg + LRU cache).

+- **Documents bypass ffprobe entirely** — probed by `document.rs` using pure Rust crates (`lopdf`, `zip`, `quick-xml`, `cfb`). Recognized extensions: pdf, docx, doc, odt, xlsx, xls, ods, pptx, ppt, odp, csv, tsv, txt, md.
+- **TUI kind filter key `5`** filters to documents. Document entries show "D" icon in file list.
