fix(client): rotating a group key asks nothing

2026-10-01T13:52:08Z

Rotation narrows rather than widens: members still connected receive the new key, and nothing already shared changes. Co-Authored-By: Claude Opus 5.5

fix(client): hosting a group asks nothing when its folder came from the picker

2026-10-01T13:49:42Z

The folder chosen in the native picker is the consent; the dialog that followed on every group creation asked the same thing twice. Co-Authored-By: Claude Opus 5.5

fix(client): the audit export never hands a spreadsheet a formula

2026-10-01T11:26:34Z

A cell starting with = + - @ (or a tab or carriage return) gets a leading apostrophe; the export carries text members chose (F-29). Co-Authored-By: Claude Opus 5.5

chore: remove a spike page served in production and an unused derivation

2026-10-01T11:25:58Z

static/webrtc-test.html posted a raw password to /login from the hub's own origin; meshbay_common/keyderive.py derived keys from a password and nothing called it (F-32). Co-Authored-By: Claude Opus 5.5

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: 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(hub): a stranger who knows your name locks only browsers you never used

2026-10-01T09:47:39Z

A sign-in from a browser that presented no token is answered with one (known_browser, kept hashed, twenty per account); a later sign-in presenting it counts failures on its own row, which nobody else can spend. Passphrase checks inside an open session (change, e-mail, deletion, device, pepper) count on the account's own row, so a locked name no longer stops its owner there either; /me reports that row. Reset and erasure forget the browsers (F-15). Co-Authored-By: Claude Opus 5.5

fix(hub): a group name fits its column and carries no control characters

2026-10-01T08:06:26Z

Over 128 characters was a 500 on PostgreSQL; line breaks, C0/C1 controls and bidi overrides are refused (joiners stay, for emoji). The creation form caps the field at 128 (F-13, what remains of it). Co-Authored-By: Claude Opus 5.5

fix(node): how a hosted group admits people is the operator's, not the hub's

2026-10-01T07:46:39Z

attach_group no longer copies join_policy and visibility from the hub's answer: they come with the operator's request (the desktop creation form, `group add --open`) and default to invite/private; the CLI says when the hub lists the group otherwise. Every string written into node.toml is escaped (toml_string) and read back through tomllib, so a group or folder name cannot write lines of its own (F-17). 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.
