chore: license MeshBay — LGPL protocol layer, AGPL for the rest

2026-10-05T07:20:38Z

The protocol layer is LGPL-3.0-or-later in every language it exists in, so any client may use it whatever its own licence: meshbay-common, and the files marked with an SPDX line — keyderive.js, crypto.js, playlist-crypto.js, transport*.js; keyring.js, transcripts.js and argon2-wasm.js on the desktop; Kdf.kt, Keyring.kt and Transcripts.kt on Android. Everything else is AGPL-3.0-or-later, which the RPM specs and package.json already declared without a licence file to back them. Two AGPL section 7 permissions: - group applications may be under any licence when they use the interface only through a named surface (static/licenses/APPLICATION-EXCEPTION.txt); the reference application is 0BSD so that copying it brings no AGPL code; - the Android application may be conveyed linked with Google Play services. Third-party code is accounted for: THIRD-PARTY-NOTICES.txt is generated from what a build ships (packaging/third_party_notices.py) for the deb/rpm venv and the frozen Windows node — PyAV's wheel grafts in libx264 and libx265, which its BSD licence does not mention — and the vendored browser libraries get their licence texts and htm-preact.js its provenance. Wheels carry SPDX metadata, RPMs %license, debs a DEP-5 copyright file, every Windows target LICENSE.txt. test_licensing.py holds the line: the LGPL layer imports nothing under the AGPL, the reference application nothing outside the application interface, and every SPDX line is one of the known ones.

fix: an MBK2 bundle is opened once and stored again as MBK3

2026-10-01T11:06:32Z

Transitional. The Argon2 run that makes M makes A, the key MBK2 bundles were sealed under; a session keeps it as a decrypt-only key (IndexedDB in a browser, the key storage in the desktop app). A client meeting an MBK2 bundle opens it — or its recovery copy — and stores the same identity as MBK3 once connected; the desktop app reseals or withdraws it as browser access says. A session without A asks for the passphrase once. Older formats stay refused by name. Replaces the unpin-and-reinvite step the 0.17 flag day required on every node. 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.

feat(client): the desktop application keeps M and every node identity in its main process

2026-09-30T14:58:31Z

keyring.js derives, opens, mints, seals, signs and agrees there; the page gets public keys and a handle. Argon2 comes from the page's own WebAssembly build (Electron's crypto has none). Without OS key storage the page keeps its keys as a browser does. A node's bundle is settled after connecting, re-sealed when the key changed. Co-Authored-By: Claude Opus 5.5
