 - **Local files:** use **⌘O**, drag files onto the player, or choose Finder's **Open With**. Multiple files form a queue in natural filename order, with automatic advance. Use **View → Show Queue** to play, reorder or remove items; **+** or dropping files onto the sidebar appends them. The queue lasts only for the session; opening other media replaces it.
 - **Streams:** use **Open Stream…** (**⇧⌘O**) or drop a supported link. YouTube supports individual videos, not playlists or channels. Miruro links must use `https://barelystarted.miruro.tv/watch/<opaque-id>/<slug>?ep=<episode>` with an explicit positive episode number; arbitrary streaming sites are not supported.
+- **Stream queues:** integrations can supply an ordered YouTube/Miruro queue with `--new-instance --queue-file /absolute/queue.json`. The same sidebar supports play, reorder, remove, previous/next and automatic advance. Only the selected item resolves, including fresh resolution on revisits; local-file batches still use natural filename order.
 - **Seeking:** click or drag the progress track or thumb to seek. The thumb centers on the cursor, clamped to the track endpoints.
-- **Miruro metadata:** titles and opening/ending intervals load independently of playback when available. Small rounded gaps mark interval boundaries in the slider. Inside a segment, **Skip Opening** or **Skip Ending** appears at the top-right below the titlebar for up to ten seconds or until the segment ends; clicking seeks to its end. Ignored offers stay dismissed until the media is closed or replaced. Missing/invalid metadata leaves playback usable, and timings may differ between cuts. Nothing skips automatically.

Inside a segment, **Skip Opening** or **Skip Ending** appears at the top-right below the titlebar for up to ten seconds or until the segment ends; clicking seeks to its end. Its background fill drains as the offer expires, with a short entrance/exit transition; Reduce Motion uses stepped countdown updates without the transition. Ignored offers stay dismissed until the media is closed or replaced. Missing/invalid metadata leaves playback usable, and timings may differ between cuts. Nothing skips automatically.
 - **Resume:** videos resume their saved position; finished videos restart from the beginning. Live and audio-only media do not save progress.
 - **Compact mode:** press **P** for a floating player; double-click it to restore. Drag noninteractive areas to move the window. Use the titlebar pin to keep the normal window on top.
 - **Quality:** YouTube defaults to SDR up to 1080p. Use **gear → Quality** for other available resolutions or automatic quality.

 The CLI opens one file or supported stream, reusing the running player by default. With no arguments, it opens or activates the player. `--new-instance` starts a separate player; `--no-config` uses built-in settings on a fresh launch. Put these options before the media argument. Before installation, use `.build/terebi` instead of `terebi`.

 Create a private reporting-session directory (`0700`) and supply a **nonexistent** progress-file destination. Terebi exclusively creates the report (`0600`), rejecting existing destinations and symlinks. CLI success means macOS accepted the launch, not that playback succeeded. Tubular consumes reporting independently of launcher lifetime; launcher exit, a final record or Tubular shutdown does not establish that the player stopped. Preserve retained sessions and restart/partial-line recovery.
 
+### Ordered stream queues
+
+```sh
+terebi --new-instance --queue-file '/absolute/private/session/queue.json'
+```
+
+The manifest is bounded to 8 MiB, version 1, and 1–4096 entries in playback order:
+
+```json
+{
+  "version": 1,
+  "items": [
+    {"url": "https://www.youtube.com/watch?v=jNQXAC9IVRw", "progress_file": "/absolute/private/youtube-session/progress.jsonl"},
+    {"url": "https://barelystarted.miruro.tv/watch/OPAQUE_ID/episode?ep=1", "progress_file": "/absolute/private/episode-session/progress.jsonl"}
+  ]
+}
+```
+
+Use canonical YouTube video pages or supported Miruro episode pages, never expiring source addresses. Stable identities must be unique even across alternate YouTube forms or different Miruro slugs. Reports must have distinct absolute nonexistent destinations, each under a canonical, nonsymlink, user-owned `0700` directory. Tubular retains each item's existing identity registration/session and stores the manifest in the first session. The CLI validates the complete document before launching; the GUI validates it again before opening any media. Invalid queues fail rather than falling back to a single stream. Queue launch requires `--new-instance`, accepts `--no-config`, and cannot combine with `--url`, `--source-file` or `--progress-file`.
+
+The supplied order is preserved (local-file batches still use natural filename order). Existing sidebar reorder/remove/play and previous/next navigation apply. Natural end advances without clearing the queue. Sources resolve only when selected, resolve afresh on revisits, and canceled/stale results cannot replace a newer selection. Labels start with descriptive page information and update from resolved titles/optional metadata.
+
+Each report is immutably bound to its stable identity in the native decoder. Switching entries drains/closes the previous writer before beginning the next; revisits append only after verifying the original private report inode, owner, permissions and link count. An unrelated or replaced file is never reopened as an owned session, and an unregistered identity is never written to the previously selected report. Only the active item owns a running writer/open report descriptor. A reporting failure is shown separately without rerouting facts or changing acknowledged playback/completion semantics. Single-stream `--progress-file` remains unchanged.
+
+Runnable queue checks: `make check-cli check-queue check-reporting check-resolved`. The existing `check-resolved` local HTTP/HLS/VTT harness also drives a real native `PlayerModel` through a mixed YouTube/Miruro queue with injected fixture resolution, stale-result cancellation, manual navigation, natural-end advancement, fresh revisits/resume and isolated v1/v2 reports. Run `TEREBI_CHECK_STREAM_QUEUE_ONLY=1 make check-startup` for focused actual CLI→LaunchServices→GUI queue delivery, native decode, manual previous/next, natural-end advancement and per-item report revisits using the existing bundled-extractor/local-media fixture. These checks require no browser or live streaming service. Full `make check-startup` includes this queue scenario too. These additions have not yet been executed as part of this change.
+
 ### Optional native metadata
 
 The native resolver requests watch-route data and safely follows bounded same-origin, same-ID, same-episode canonicalization envelopes, including HTTP-200 redirects. It accepts JSON and newline-delimited `text/sveltekit-data`, decoding only the needed response-local tables and episode promise. Bodies and traversal are bounded; unrelated source promises are not used for playback.
