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

fix: an identity signs a named kind, and a device approval answers a request

2026-09-30T19:04:39Z

The desktop main process builds every transcript itself from fields (transcripts.js) and signs no raw bytes; the page's identity has the same contract (crypto.js transcriptFor). The keyring seals no bundle while browser access is off. On the node, device_add must redeem a pending request filed by the same keys, and device_revoke is signed under its own prefix (meshbay:device_revoke:v1), so a retirement signature admits nothing.

fix: a member can no longer lock a node, crash it with a link, or stop hub cleanup

2026-09-30T09:22:24Z

- node: only a wrong code counts towards the join lock, now per account (5) as well as node-wide (20), and it is consulted only when a code is tried. Every member reconnecting gets the group key through join_request, so a lock checked before recognition let one member refuse it to everyone. - node: link previews read the body as a stream and stop at the cap, counted on decoded bytes; a declared oversized image is not read; 15 s total deadline; image decoding off the loop. `client.get` had buffered the whole (decompressed) response before the caps looked at it. - hub: the daily purge of never-verified accounts detaches their IP-log rows (keeping the name) and clears every other reference first, and each cleanup step runs on its own. On PostgreSQL the bare DELETE violated the ip_logs foreign key and stopped every purge behind it for good. Co-Authored-By: Claude Opus 5.5

fix: bound pending admin challenges and sign every value an op acts on

2026-09-28T19:14:10Z

Any member could make a node hold unbounded challenge requests; a connection now keeps at most 8, 64 KiB each. root_add, group_attach, invite_create and tmdb_config signed less than they did; their subjects are now canonical JSON of every value (the TMDB token by SHA-256). MNP 5.0, floor kept at 4.0. Co-Authored-By: Claude Opus 5.5

refactor(node): section headers follow the code they introduce

2026-09-24T14:45:38Z

Three headers stayed in webrtc_server when their sections moved; they now sit above the same methods in blobs.py and admission.py. Two that were only a title over what is now a whole module are dropped. Co-Authored-By: Claude Opus 5.5

refactor(node): move invitations, joins and device linking out of webrtc_server

2026-09-24T14:45:38Z

AdmissionMixin in transport/webrtc/admission.py, with the invite handle pattern and the join attempt bounds. Co-Authored-By: Claude Opus 5.5
