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
