 Two or more checked videos launch `terebi --new-instance --queue-file '/private/session/queue.json'`. The private version-1 manifest contains ordered canonical episode/video page URLs and one independent `progress_file` per item. Terebi reuses its queue navigation and resolves each item when selected, not in advance; no expiring playback sources are stored. Each item's watching/watched state and resume identity remain independent, including after Tubular restarts. Single-video launches retain the command above. See the [queue contract](docs/terebi-url-playback-handoff.md#ordered-stream-queue-handoff).
 
+**Cmd+Return or Ctrl+Return** (`video.enqueue`) sends the same checked rows, or the hovered row when none are checked, to a running Terebi queue without replacing its current playback. Both bindings are available on every platform; the terminal must transmit the modified Return, or you can rebind the action. Enqueue always uses `terebi --enqueue --queue-file '/private/session/queue.json'`, even for one video, preserving independent per-item progress. If Terebi is not running, it starts with that queue. Plain Return still opens a new instance. These shortcuts do nothing on Miruro catalog titles or saved shows and do not submit text inputs.

+The manifest contains 1–4,096 entries. Plain Enter uses it for batches of two or more; a single item retains `--new-instance --url` and `--progress-file`. Enqueue uses a manifest even for one item. `--queue-file` requires either `--new-instance` or `--enqueue`, an absolute manifest path, and no other media argument or global `--progress-file`; those two launch modes cannot be combined.

POSIX-canonical report paths deduplicate macOS `/var` and `/private/var` aliases. Invalid batches fail rather than silently playing only their first entry.
 
 Tubular validates all identities, snapshots and available session capacity before allocating a batch. It creates one existing-format snapshot/reporting session and identity marker per item; it never creates Terebi's report files. The manifest is `0600` inside the first retained `0700` session directory and contains no source URLs or transport credentials. Retention and the shared 4,096-session cap are unchanged; inactive queue entries count toward the cap too.

 - Both actual terminal interfaces were exercised with offline saved rows and a capture launcher: checking in reverse order produced a private two-item manifest in displayed order; successful submission cleared checks and the next Enter used single-video URL playback. This fixture did not run Terebi.
 - Terebi: `make check-cli check-queue check-reporting check-resolved all` passed. Headless native playback exercised mixed YouTube/Miruro queues, stale-result cancellation, manual navigation, natural-end advancement, fresh resolution/resume on revisits and isolated per-item reports.
 - The packaged GUI smoke did not complete: native state snapshots stalled. Temporary tracing and probe files were removed. Further UI testing was stopped at the user's request and remains user-owned; no complete GUI smoke or visual-layout pass is claimed. The TODO remains open for that confirmation.

+## Append to a running player
+
+```sh
+terebi --enqueue --queue-file '/private/session/queue.json'
+```
+
+`video.enqueue` defaults to both Super/Cmd+Return and Ctrl+Return. It shares plain Enter's checked-display-order selection and hovered-row fallback in video/episode lists, previews and offline collections. Miruro catalog/show rows and text inputs do not enqueue. Plain Enter remains a new-instance launch.
+
+The CLI delivers a manifest reference through an explicit-app native URL-open event, so later submissions reach an already running player rather than relying on startup arguments. The receiver appends in supplied order without restarting current playback, changing paused/playing intent, cancelling current resolution or resolving appended items early. An empty or newly launched player starts the first queued item. OS-level delivery to a running packaged app still needs user confirmation; headless receiver checks are not LaunchServices proof.
+
+The complete request is rejected on an identity already in the current queue, a retained report identity, a retained report path, or the original single-video report identity. Removing a row does not release its registration. Registrations are atomic; failed batches do not reserve their valid prefix. The original single-video report remains independently navigable, and unregistered identities cannot leak into it once queue reporting is active. Errors after OS handoff appear in Terebi; Tubular's checks retain the existing clear-on-successful-launcher-spawn policy.
+
+### Enqueue verification
+
+- Tubular: `cargo fmt --all`, `cargo test --locked` (**233 passed**), `cargo build --locked` and built `--help`; Rust launcher diagnostics were clean.
+- Actual YouTube and Miruro terminal interfaces: reverse-checked rows produced display-ordered enqueue manifests, cleared checks fell back to the hovered row, Ctrl/Super+Return and an F12 override worked, and plain Return still used `--new-instance --url`. Six handoffs used private `0600` manifests in `0700` session directories with distinct report destinations. The capture launcher did not run Terebi.
+- Terebi: `check-cli`, `check-queue`, `check-reporting` and `make all` passed. A regression check first failed on rebinding the original single-video identity and passed after binding it independently of appended reports.
+- Headless native enqueue smoke with local video-only HLS passed: repeated delivery while paused/playing, unchanged current selection/revision, lazy mixed-provider append, natural-end advance, navigation/revisits, atomic rejection/rollback, isolated original/appended reports and empty-player startup.
+- Full `make check-resolved` stopped in the pre-existing mixed-queue natural-end scenario at `Could not start Core Audio (560227702)` before reaching enqueue. No full A/V-suite pass is claimed. No packaged-GUI/LaunchServices smoke or visual-layout confirmation was performed; the app was built, not installed. Temporary terminal/server fixtures were removed.
