* fix(hub): trace the subtitle path end to end in the playerChristophe Besson2026-09-171-2/+24
| | | | | | | | | | | | | | | | A subtitle button that spins for ever and never shows a track could not be told apart from a node that answered, a blob that never arrived, or a track attached with no cues in it: the whole path was silent. Every step of it happens on someone else's machine, over a link, against a file that may be gigabytes, so the only question worth asking when it does not finish is which step did not — and nothing recorded that. It now logs the request, the node's answer with hash, size and elapsed time, the fetched blob and its chunk count, the attachment, and the live TextTrack's mode and cue count. A failure says how long it took before failing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UGY17EPph5LsLzePPXhUVc
* 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.
