fix(node): name members admitted without an invitation name

2026-10-07T20:20:45Z

A member who joined by link, by a new device or into an open group was pinned in the roster with no name, so the audit log showed only the first characters of their id. The hub's MNP token now carries the account's username, and after the handshake the node writes it into the roster for an account whose name is empty. An invitation's name is never overwritten; the name is a label, authority stays on `sub`. Co-Authored-By: Claude Opus 5.5

perf(node): list a group's directories off the event loop

2026-10-07T19:31:10Z

Every full index walked all roots on the loop, and a node with several large roots stopped answering for seconds. Walk directories only, on the roots' disk thread; index_sync is spawned and still answers on failure. Co-Authored-By: Claude Opus 5.5

refactor(mnp): remove ten operator messages no client sent

2026-10-02T08:51:19Z

node_status, node_settings_set, roster_read, denylist_read, denylist_clear, node_reload and the signed gek_rotate, member_unpin, transfer_limits, group_detach leave MNP 6.0; the Node page and the CLI do this work over loopback. Their ops keep their tests, moved to the ops level. Co-Authored-By: Claude Opus 5.5

feat(mnp): sharing a folder is decided on the node's machine only (MNP 6.0)

2026-10-02T08:20:09Z

root_add, root_update and group_attach leave MNP: adding a directory and switching writable/removable go through the loopback API (native dialog in the desktop app) or the CLI. The operator's Settings tab still lists the roots from any browser, read-only. The desktop app refuses to sign those ops; a loopback flag change now reaches open pages (publish_roots).

fix(node): the clear fields beside a chat message are bounded

2026-10-01T11:25:35Z

sender_name and thread_id travel in clear beside the sealed envelope and were stored and relayed whatever their type and size. A name longer than a username or a thread id that is not a short id is now dropped (F-27). Co-Authored-By: Claude Opus 5.5

fix(node): a member is told a media tool failed, not what ffmpeg said

2026-10-01T11:24:11Z

Stream, transcode and subtitle failures sent the exception's text — operator paths, versions — to the member. Fixed messages now, the cause in the log (F-24). Co-Authored-By: Claude Opus 5.5

fix: downloads are marked and keep their extension; Explorer files are refused

2026-10-01T09:47:39Z

The desktop app writes the Mark-of-the-Web on each file it saves on Windows, as a browser does. Bidirectional controls are reserved characters in a saved name (portable-name.js and paths.sanitize_for_download, and again in the main process), so a name cannot display one extension and carry another. The node refuses uploads of files Windows Explorer acts on by itself: desktop.ini, .lnk, .url, .scf, .library-ms, .searchConnector-ms (F-19). Co-Authored-By: Claude Opus 5.5

fix(node): one member holds a share of the node, sized past real use

2026-10-01T08:34:26Z

128 peer sessions on the node, at most 64 per account (the hub names the account with each offer; the node's own account is not counted). One account plays at most half the stream slots, rounded up, and runs two subtitle extractions at once. Frames after the handshake are 8 MiB (was 64), decoded with per-container bounds, and a frame refused for either ends the session instead of jamming its buffer (F-16). Sized for the heaviest real member: twenty groups on one node, three devices and a tab, up to 52 sessions. Measured: ~0.15 MiB and one fd per idle session. Co-Authored-By: Claude Opus 5.5

fix(node): an upload never replaces a file, nor shares a part with another

2026-10-01T07:57:11Z

A name an upload in flight will take is reserved; each upload writes its own `name..part`; the finished file is published by a hard link, which refuses an existing target, and takes the next free name if one appeared meanwhile — the last ack names it. Two members sending one name at once wrote one part and published it twice; a file copied in during an upload was replaced (F-09). Co-Authored-By: Claude Opus 5.5

fix(node): ffprobe over a member's file is bounded, and stopped when it is

2026-10-01T07:53:34Z

probe_video waits 30 s at most and kills ffprobe on a timeout or when its caller gives up — a cancelled wait left the process running. The seek probe kills what it timed out on. Stream, subtitle and enrichment requests no longer hang on a file that keeps ffprobe busy (F-18, timeouts; the protocol whitelist was dropped: ffmpeg already confines nested protocols of a local input, measured on 8.0 against HLS and concat inputs).
