* docs(hub): say what the subtitle track's mode effect was measured to doChristophe Besson2026-09-171-5/+9
| | | | | | | | | | | | | | The comment claimed a <track> appended after playback started is not shown by its `default` attribute. Chrome shows it: in a headless run the TextTrack read back "showing" before the effect had touched it, with its cues already parsed. The effect stays, for the two reasons that are true — `default` says nothing about turning subtitles off again, and an explicitly assigned mode means the same thing in every engine — but the reason written beside it was not one of them.

* feat: embedded subtitles in the video player (MNP 3.3)Christophe Besson2026-09-171-4/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MSE decodes no in-band text track, so a subtitle cannot ride inside the fragmented MP4 the player is fed. The node extracts one track whole, converts it to WebVTT and caches it under its own hash; the client pulls that blob through the ordinary file_req/chunk path and hangs a <track> on the video element — the same indirection as a TMDB poster or an audio transcode, which is what makes a film's subtitles extracted once in the life of the file rather than once per viewing. Whole-file also makes the cues absolute, so a seek and an audio-language change both leave the track untouched. **The ordinal counts every subtitle stream, including the ones never listed.** Only text codecs are offered: a bitmap track (PGS, VOBSUB — about a fifth of a real library) has no path to WebVTT without OCR, and one extracted anyway yields a header with no cues, which is a menu entry that shows nothing and reports no error. Numbering the survivors of that filter would give a PGS/SRT/SRT file the ordinals 0 and 1 for its text tracks and `-map 0:s:0` would then extract the PGS — the same trap `AudioTrack.ordinal` exists for, one level deeper. A fixture whose first subtitle stream cannot be decoded pins it, and the handler checks membership of the probed list, never a range. Additive and MINOR: the selector is drawn from `subtitle_tracks` in the node's own `stream_init` and from no version number, so `subtitle_req` is never sent to a peer that would not answer it. The floor stays at 3.0. Also here: a failed extraction never touches playback, a superseded reply cannot install its blob over a newer choice, and `_languageName` is shared with the audio labels — lifted by both label harnesses, since a lift that names one function stops covering the rule the moment logic moves out of it. Tests: 9 node (tracks told apart by the words in the extracted cues, not by tags), 10 client. Full suite green: 1545 node/common, 1252 hub.

* feat(hub): give the audio-language button a glyph of its ownChristophe Besson2026-09-171-1/+1
| | | | | | | | | | | | | | | | The audio-track selector was drawn with `volume` — the same glyph the music player uses for its level control, and the same one the browser draws a few dozen pixels below it, since the video player mounts `<video controls>` and gets the native volume speaker with it. One drawing, two meanings, in one window. `speech-pair` is two offset bubbles: the same line, said twice, which is what the button chooses. Nothing crosses anything — the set is stroked with no fill, and two overlapping outlines read as a tangle at 20 px — and it leaves the conventional subtitle glyph free for the button planned beside it.

* feat: let the viewer pick the audio trackChristophe Besson2026-09-171-3/+114
| | | | | | | | | | | | | The streaming path mapped 0:a:0 unconditionally, so a dubbed film played in whichever language was muxed first and the others were unreachable. The node now enumerates the tracks in stream_init and honours audio_track in stream_req; switching is the seek path, since one ffmpeg carries one track. MNP 3.2, additive: the player draws its selector from the node's own list and never from a version number, so an older node is never asked for a track it would ignore. MNP_MIN_SUPPORTED does not move. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
* fix(node): inline @owner next to group name, fix buffering layout shiftChristophe Besson2026-09-061-8/+7
| | | | | | | | | Put the @owner handle on the same line as the group name (flex baseline) to save a row on mobile. Move the video buffering indicator inside the video-container as an absolute overlay so it no longer pushes the video down when it appears briefly during seeks.

* feat(video): hold a Screen Wake Lock while a video is openChristophe Besson2026-08-261-0/+43
| | | | | | | | | | | | | Purely additive and isolated from the streaming/transport code: touches no DataChannel, SourceBuffer, or playback state, so it cannot itself cause a stall or regress existing playback (PC/Electron included) — feature-detected and try/caught, a no-op wherever unsupported or refused. Sidesteps the commonest real-world trigger for the WebRTC-drop recovery (the phone auto-locking on its own idle timer while someone just watches). Does nothing for a deliberate power-button lock or backgrounding the tab — released automatically in both cases per spec — so the reconnect path is still what handles those.
* fix(transport): auto-reconnect after WebRTC failure, without dropping ↵Christophe Besson2026-08-261-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in-flight streams/downloads Confirmed live (client trace + node logs, mobile screen-lock ~5min): ICE goes disconnected -> failed within ~10s on both ends, but the DataChannel's readyState stays "open" throughout, so nothing failed fast — every request just sat out its own 8s/30s timeout, matching the reported symptom (poster spinners, blocked chat, dead new streams). transport.js: on connectionState "failed", reject pending requests immediately (TransportLostError) and start a self-contained reconnect loop (capped exponential backoff, redoes the full signaling handshake — the node already discards the old session on its own "failed"/"closed", so there is nothing lower-level to resume). New hooks: onNeedToken (fetch a fresh JWT, since the captured one may have expired during the outage) and onReconnected (let a consumer resume something that was mid-flight). file-utils.js: pipelinedDownload retries a lost chunk instead of aborting the whole transfer — covers Files downloads, poster/thumbnail fetches, and music-player.js's blob-based track download, all of which go through it. video-player.js: onReconnected reissues the existing seek-to-current-time path, which already knows how to land a new stream_init on the live SourceBuffer without resetting playback. Playing audio is unaffected either way — musicbay.md's design downloads a track to a blob before playing it, so a dead transport was never a network dependency for what is already playing. Stays on this branch until confirmed by real-device testing.
* fix(node,hub): always transcode video audio to stereo AAC, never copyChristophe Besson2026-08-231-10/+55
| | | | | | | | | | | | | | | | | | | MSE only decodes AAC/Opus, so copying a source's real audio codec left non-AAC files silently unplayable in-browser (E-AC-3 additionally made ffmpeg itself refuse to write the fragmented MP4 header). Audio is now always transcoded to AAC and downmixed to stereo — multichannel AAC is accepted by ffprobe/VLC but silently rejected by some browsers' MSE decoder once real fragments are appended, which forces the SourceBuffer out of its MediaSource with no explicit error. Video stays copy-only. Also: report a clear client-side error instead of a bare STREAM_END when ffmpeg exits nonzero before producing any output, add video-element/ MediaSource error logging on the client for the next time this class of bug needs diagnosing, and fix a hub test that had grown too broad a scan window after an earlier, unrelated transport.js change.

* feat(hub): split the group UI into a pluggable "applications" architectureChristophe Besson2026-08-231-0/+992
GroupPage's 6620-line app.js carried Chat and Files wedged in directly, with no way to add another group-level app without touching the shell itself. It is now app.js (routing, non-group pages) plus nine focused files — apps.js (the registry), chat-app.js, files-app.js, video-player.js, group-page.js (the shell), group-settings.js, hub-client.js, icon.js and file-utils.js — with docs/apps.md as the checklist for adding one (Videos/Music/Photos are sketched there, not built). Node side gained the matching enablement mechanism, mirroring member_upload exactly: a roster setting, a signed apps_enabled op enforced by _has_admin_authority, exposed in the handshake ack. Operators toggle applications per group from Settings, which also gained a small reorder: Invite, Pairing, Applications, Shared directories, Uploads, danger zone, Your devices, Members. Two bugs surfaced during the split, both missing an import across the new file boundary and invisible to node --check or a module-load probe since they only throw when the code path actually runs: - group-page.js called onRefreshAuth on a stale-token handshake rejection, but app.js never imported refreshAccessToken from hub-client.js — so a brand new member (including a group's own creator) hit "Not a member of this group" and the retry silently failed, throwing before it could refresh the token. - chat-app.js called getLocale() for message timestamps without importing it from i18n.js. Opening Chat on a group with real messages threw mid- render; uncaught, that appears to wedge Preact's render scheduler, so every button on the page stopped responding until reload. Caught the second class of bug with a proper no-undef audit across all split files (a temporarily installed ESLint 9, since the system one is too old to parse this codebase's syntax) rather than trusting grep. 827 tests pass; 6 new ones cover the apps_enabled policy.
