+- Documented private-runtime launcher installation, simplified first-run setup, custom app locations, legacy launcher migration, and package-managed updates. Updated release-note download guidance for the bundled runtime and Windows launcher.
+- Documented the bundled Bun runtime's MIT and LGPL licensing, where the notices live in the app, and the corresponding-source release asset. The AUR package now lists the bundled runtime licenses and installs their notices under `/usr/share/licenses/subminer-bin`, and `subminer-assets.tar.gz` includes the same notices.

+- Made every installed and downloadable launcher use the Bun runtime included with SubMiner. Added a Windows `subminer.cmd` download, persistent private runtime caches for Linux and Windows, and migration for recognized legacy launchers. Deferred migrations survive overlapping update checks and remain pending when startup cannot safely refresh the launcher.
+- Simplified first-run setup to a single optional launcher control, with runtime repair guidance shown only when needed.

-- Broadcast-style Japanese caption tracks (Crunchyroll JA subs) that split one sentence across two positioned events now publish it as a single line, so `preserveLineBreaks: false` flattens it, the sidebar lists it once, and mined sentences are whole. Rows from two different speakers, sound effects, and labeled turns still stay on separate lines.

+- Sync uses compressed, incremental rsync transfers on compatible macOS and Linux machines, caching the last received snapshot per peer to reduce traffic on subsequent syncs. Cache helpers work through the launcher; older apps and launchers fall back to compressed transfers without an upload cache.
+- Machines without compatible rsync, including Windows endpoints, automatically use compressed scp transfers.
+- Rsync explicitly uses SSH and aborts transfers that exceed 30 minutes before merging.

+- Generate local Japanese SRT subtitles with whisper.cpp from a standalone modal opened with Ctrl+Shift+G, the empty subtitle sidebar's generation button, or `subminer generate-subs`, with shared progress reporting, cancellation, safe output files, and automatic loading into the matching mpv video. The sidebar button hides while subtitle lines are loaded.
+- Configure an existing multilingual model in Settings or choose an official multilingual model, including quantized variants, in the modal or launcher. The modal shows download sizes, speed and accuracy guidance, and a recommended starting model before explicitly downloading a verified SubMiner-managed model. Executable paths are optional overrides; empty fields find whisper-cli, ffmpeg, and ffprobe on PATH. The modal's Local tools check and the launcher name any missing executable and its setting before downloading a model or extracting audio, and generation confirms the destination directory grants write and search permissions up front.
+- Optionally select Focus on spoken dialogue in the modal and use Download speech detection model to install the separate Silero model with progress and cancellation. The choice lasts for the session; a configured VAD model path sets the default. Retain uncertain audible sections so VAD rejection does not discard dialogue under music, accepting that songs may also be transcribed. Keep passages intact within Whisper's audio window, split longer passages near detected speech starts or quiet pauses with overlapping context to reduce early subtitle timing, and combine overlapping duplicate cues even when punctuation differs. Run each passage in a fresh Whisper process to prevent repeated-character output caused by state carried between files, at the cost of reloading the model per passage. Preserve original media timing and separate repeated dialogue.
