* feat(hub): client-side transfer leases and the transfers panelChristophe Besson2026-09-081-11/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Steps 5 and 6 of ~/next/improve-downloads.md. The node has handed out slots since step 2 and nothing asked for one; now the client does, and the panel shows what is happening. `transport.openTransfer()` returns a Lease: `acquire()` resolves when the node grants, `release()` gives it back exactly once, and nothing else in the client speaks to the node about slots. Whether a node hands out slots is read from the handshake ack rather than guessed from a timeout — "no answer yet" and "this node will never answer" are indistinguishable in time, and guessing wrong either stalls every download or defeats the cap. Two things exist only because a queue can lie: a watchdog re-asks when a pushed grant does not arrive (the node is idempotent on `tr`, so asking again is free), and a grant for a transfer the page has forgotten is handed straight back rather than held until the node's deadline. The slot is asked for **after** there is somewhere to write, and that ordering is load-bearing: opening a target takes thirty seconds of streamed-download timeouts, or as long as somebody leaves a Save As dialog open, and a grant not taken up in time is revoked. Moving it earlier looked better and broke three downloads into one. Pinned by a test. The panel groups by state — running, waiting, finished — rather than re-sorting a flat list, so a row moves only when its own state does. The ETA is withheld until the speed window holds real measurement: a figure from the first two chunks swings between four seconds and an hour, and people plan around the first number they see. One live region announces state changes and not progress. Three silent paths closed on the way: a download refused for want of a user gesture (a browser grants one file picker per gesture, and downloading three files is one gesture) now falls back to the streamed path, which needs none; a click with no connection says so instead of doing nothing at all; and a queued transfer counts as busy, so a transport is never closed under one that is waiting for a grant that could then never arrive.

* fix(hub): never collect a large download in the pageChristophe Besson2026-09-081-9/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `pipelinedDownload` with no writable allocates `new Array(totalChunks)` and keeps every decrypted chunk, so whatever `_openDownloadTarget` returns null for is held whole in RAM. That floor had no upper bound: the `!window.showSaveFilePicker` branch returned null at any size, so on a browser without the File System Access API a 20 GB film went to memory whenever the streamed path did not answer. Nothing logged, nothing refused; the symptom was the tab dying, with no error attributable to this code. MEMORY_CEILING is 100 MB and every `return null` in that chain now goes through a guard that throws above it. The refusal names the size, the limit and why the streamed path declined, and lands in the transfers panel as a failed transfer rather than in a console nobody opens. This is a guard, not a limit on what can be downloaded: with the streamed path primed and retried (previous commit), a file of any size still goes to disk progressively on every browser. Two things had to change for that to be true: - the streamed path is now tried in "ask" mode too, for a file over the ceiling on a browser with no Save As of its own. The mode decides whether to show a dialog; it was silently deciding whether a film could be downloaded at all; - FilePreview had no size check whatsoever — a multi-gigabyte PDF or .csv was fetched whole, and the text branch decoded all of it to keep 500 000 characters. It refuses above the same ceiling and offers the download. ZIP_MAX_BYTES (512 MB) and the ceiling do not contradict: the archive limit bounds the archive, the ceiling bounds what may be built in the page, so a 400 MB zip is allowed when there is somewhere to stream it and refused when the only route left is memory. The build-in-memory confirmation only appears below the ceiling now. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HCGdheDLxGReuKHga3BtST
* feat(hub): cap a directory zip at 512 MBChristophe Besson2026-09-081-5/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An arbitrary ceiling, not a technical one: the zip writer streams and holds one chunk plus a record per file, so it would happily produce a hundred gigabytes. Past half a gigabyte the honest answer is a subfolder at a time, or the files individually. Enforced in file-utils.js's downloadDirectory, which is the one implementation behind every zip button — Files' single folder, Files' multi-folder selection, and the Photos album button (docs/photos.md §3). - Per directory, not per selection: Files zips a whole multi-directory selection in one click, so an oversized folder is refused and its siblings still download. - Before _openDownloadTarget, so no save dialog opens for an archive that is never going to be written. - The bound is strict, so a folder of exactly 512 MB still goes through. - Counted in the 1024-based units formatSize already prints, so the number in the refusal is the number in the constant. group.zip_too_large in all ten catalogues. test_zip_size_limit.py runs the module under Node and pins the refusal, the inclusive bound, and that nothing is asked or started when a folder is over. The user guide's "a 40 GB folder costs 40 GB of disk" is no longer true and now documents the cap instead.

* refactor(hub): drop the base64 chunk fallback and the dead HTTP file clientChristophe Besson2026-09-031-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | With MNP 0.15 no node can emit a base64 `file_chunk`, so the browser's fallback for that shape is unreachable. Three things go with it: - `file-utils.js` kept a third branch below the fallback that base64-decoded `chunkMsg.ct_b64 || chunkMsg.data_b64` when neither was present, i.e. decoded `undefined` and wrote the result into the file the user was saving. A chunk we cannot decrypt now stops the download with an error naming the file and suggesting the node is older than the page. Deliberately not in `_isRetryableTransportError`: this is a version mismatch, not a bad moment on the link. - `crypto.js` `decryptChunk` (base64) was the real path until Phase 9.15 and has had no caller since. - `crypto.js` `decryptFile` was never called in any commit. It fetched `${nodeUrl}/file/${id}/${chunk}?token=` in a loop — the node's unauthenticated HTTP file API, which is finding C1 and was deleted in Phase 11.5. A client for an endpoint that no longer exists, kept alive by being exported. `decryptChunkBin` — every file download and every video segment — is untouched. `packages/meshbay-client/ui/` was resynchronised with `npm run sync-ui`.

* fix(transport): auto-reconnect after WebRTC failure, without dropping ↵Christophe Besson2026-08-261-1/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* feat: add Photos group appChristophe Besson2026-08-251-0/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new group application (docs/apps.md's plug-in mechanism), following the plan in docs/photos.md. Unlike Videos/Music: several photo roots per group instead of one (photo_roots is a set, one signed op replaces it whole), a single album-grid view with no third-party matching step, and per-photo info read from the file's own EXIF at index time — no metadata service, no credential, no outbound network call at all. Protocol (meshbay-common, MNP 0.10 -> 0.11, additive): `taken_at`/`camera` on IndexEntry; `photo_roots`/`photo_roots_ack`; `OP_PHOTO_ROOTS`. Node: roster.py stores photo_roots as a group_settings entry (JSON list, same shape as enabled_apps); ops.py/webrtc_server.py validate and sign the whole set in one op, same pattern as apps_enabled; a new PhotoEnricher (indexer/enrich_photo.py) runs Pillow in its own small bounded pool, separate from the video/audio pools, producing a resized thumbnail plus the two EXIF fields — never GPS, checked by a grep-based regression test. Client: photos-app.js — one album card per directory containing images, a per-album photo grid, and a lightbox with next/previous (keyboard and buttons), zoom in/out/fit/100% starting from the actual on-screen fit percentage, and a "zip this album" button reusing files-app.js's own zip mechanism (lifted into file-utils.js's downloadDirectory so both call the same implementation). group-settings.js gets an add/remove multi-root picker, distinct from Videos/Music's single-value one. Bugs found and fixed before this ever shipped, worth keeping the story of: - enrich_photo.py read width/height from the raw image *before* applying EXIF orientation correction, and read DateTimeOriginal off the plain 0th-IFD Exif object — a real camera stores it in the Exif sub-IFD, which Pillow only exposes via get_ifd(Exif). A flat, hand-built EXIF dict round-trips through Pillow either way, which is exactly what would have hidden both bugs; the regression test builds EXIF with piexif instead, matching what real hardware produces. - photos-app.js's album grouping stripped a trailing path segment from entry.path under the assumption it still carried a filename — it doesn't (files-app.js's own convention: e.path is already the containing directory), so every album collapsed one level into its parent. Found live against a real multi-folder library. - transport.js's ADMIN_OP_TYPES allowlist (already the fix for an identical bug on video_root/apps_enabled, see 4783d81) was missing photo_roots: its admin_challenge matched no pending request and was silently dropped, so saving a photo root just timed out after 30s with no error. - daemon.py pruned a thumbnail when its file left the index (root removed or reconfigured) but never forgot the content hash was "already attempted" — the same bytes reappearing under a renamed/relocated root (an operator's real workflow) were then permanently skipped, forever, with nothing to indicate why. Discarding the attempt alongside the cache entry on prune is what makes pruning actually reversible. - packages/meshbay-client's app:// protocol handler served every file with no Cache-Control header, so Chromium was free to serve a stale cached copy indefinitely — none of several `npm run sync-ui` + reload cycles during development actually picked up the new code until the renderer's disk cache was cleared by hand. Now sends Cache-Control: no-store. - the lightbox's zoomed image used flex centering (align-items/ justify-content: center) combined with overflow: auto — a well-known trap where the browser centers overflowing content by shifting it, and the leading half of that overflow (here, the top of a zoomed photo) sits outside what the scrollport can actually reach. Reported live as "unusable". Fixed by switching to top/left alignment once zoomed.

* feat(hub): play audio files from Explorer, scoped to the current folderChristophe Besson2026-08-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Audio files were invisible to file-utils.js's canPreview, so their name never rendered as a clickable link and the toolbar's Play/View buttons never enabled for them - the only way to do anything with an audio file in Files was to download it. - file-utils.js: canPreview now includes 'audio' alongside image/ video/document. - files-app.js: the toolbar's canPlay/canView split treats audio like video (Play, not View) rather than falling into the generic preview path, which was never built for it anyway. - group-page.js: onPreview routes an audio entry to onPlayQueue - the same persistent player Music uses - instead of the preview modal. Deliberately not Music's artist/album grouping: the queue is every audio entry sharing the clicked file's literal containing directory (entry.path), sorted by filename, so previous/next in Explorer stays scoped to what's actually in that folder, tags or no tags. onPlayQueue already replaces whatever queue is playing unconditionally, so starting a track from Files while Music (or another Files folder) is already playing needs no special handling - it's the same "just a new queue" path either way. Client-side only, no protocol/index change. npm run sync-ui re-run. Full suite: 1129 passed, no regressions.

* feat(hub): split the group UI into a pluggable "applications" architectureChristophe Besson2026-08-231-0/+207
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.
