feat(hub): one account, several linked nodes

2026-10-15T07:33:28Z

An account links up to MAX_NODES_PER_ACCOUNT node keys (node_keys table) instead of the one users.pk_node_ed25519; the migration carries each account's key over and the downgrade keeps the last one linked. /v1/nodes/auth accepts any linked key, and its token names the key that won it (nk). PUT /me/node_key adds a key, idempotently, 409 past the limit; DELETE /me/node_key names the key: a browser session any of its own, a node only its own. Unlinking a key closes that node's socket and refuses its tokens at once, on REST and on the socket; the account's other nodes are untouched. /pubkeys no longer gives a node key to other accounts, and gives the caller its last linked one, which installed desktop apps read. The node reports waiting_for_node_key while its key is unlinked and signs in again as soon as the hub says so, so a key linked again is back within seconds; unlinking itself signs in first to hold a token naming its key. Profile -> Linked nodes lists each node (connected, last seen, IP, linked since, This machine in the desktop app) with Copy and Unlink, and adds a key by hand. The Node page banner, Create group and the desktop app add this machine's key instead of replacing another's. Messages that pointed at Settings -> Link Node point at Profile -> Linked nodes.

feat: notifications on Android while closed, with nothing to install

2026-10-09T10:08:31Z

The phone fetches what is new every fifteen minutes with a poll secret (POST /v1/push/poll) that reads notification lines and nothing else. When a UnifiedPush distributor is already installed, the hub also pushes at once, encrypted to the phone (RFC 8291); losing the distributor falls back to fetching. The hub now honours "disable all notifications" itself: create_notification creates nothing for that account, as it already did for a muted group, so neither switch lets anything reach a phone. The interface used to be the only reader of the account-wide switch. Push endpoints are member-supplied URLs: a send refuses non-public addresses, connects to the address it checked, and follows no redirect. Android build untested here (no SDK on this machine).

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

feat(hub): a bundle pepper per account, handed only to a proven session

2026-09-30T11:55:59Z

Sealed at rest and bound to the account; returned by sign-in, device sign-in, a passphrase change and GET /me/bundle-pepper, never by a refresh, to a node token, in a token or in a log. Erasure clears it. Co-Authored-By: Claude Opus 5.5

fix(hub): the admin allow-list grants an account, not a username

2026-09-30T10:37:31Z

Each name in admin_usernames is pinned to the first active account seen holding it (admin_pins), so a name freed by a deletion grants nothing. Co-Authored-By: Claude Opus 5.5

fix: only the owner decides who hosts a group, and nobody is made a member unasked

2026-09-30T09:49:56Z

- hub: a node may host a group only if its account owns it or the owner approved that node (new `group_hosts`). Membership was the ceiling, and every member holds the group key, so any member's node could register as a host and be the one clients kept. A node claiming a group it may not host is recorded as a request; the owner is notified once and approves or refuses it (GET/POST/DELETE /v1/groups/{id}/hosts[/{node_id}]), which takes effect on a connected node at once. - hub: an owner adding a username creates an invitation (new `group_invitations`), accepted or declined by the invitee (/v1/groups/invitations, /{id}/invitation/accept|decline). Until then the group is not listed, not dialled, not searched and not in any token. Invitation links, open joins and group creation still make members directly: they are the account's own act. - hub: the MNP token names only the group it is minted for (group_id is now required), so a node operator no longer learns a member's other groups. - SPA: invitations on the home page; invited people and host requests in the group's settings; the transport sends group_id. Ten catalogues. - Browser probes for both screens, run in Chrome and Firefox. - Design §5.2, §7.2, §7.3, AV32, AV33; protocol §6.3; user guide. Co-Authored-By: Claude Opus 5.5

feat(hub): reports from public-group members, decided by an administrator

2026-09-28T20:06:07Z

A report needs a person's account at least a day old, membership of the public group, and fits a daily allowance per account. Past the threshold a hash is queued and administrators are notified; blocking without review is an instance setting, off by default. Report menu item in public groups, Reports tab and settings in the admin panel. Co-Authored-By: Claude Opus 5.5

refactor: remove the public-content swarm

2026-09-28T19:35:20Z

Nodes registered the hashes of their public groups on the hub and nothing ever read them back. Routes, model and node registration removed; a migration drops swarm_sources. No node sends the hub a content hash now. Co-Authored-By: Claude Opus 5.5

feat: invitation links no longer bound to an e-mail address

2026-09-25T15:10:15Z

A link is redeemable by whoever opens it first, so it can be sent by any messaging app. The address is optional (mail + label only); a link lives 7 days, fixed. Adds a Share button; see MESHBAY_DESIGN.md §3.4. Co-Authored-By: Claude Opus 5.5

feat(hub): invitation-link tickets bound to a verified address

2026-09-23T15:46:48Z

group_invite_links holds sha256(ticket) and the invitee's address blind index; redeeming grants membership to that account only. Owner-only create/list/cancel (a node token may create, never mail), 20 outstanding per group, optional mail written by the hub itself and capped at 10 per sender per day (mail.invite_link_daily_cap). MESHBAY_DESIGN.md §3.4 now carries the whole link design. Co-Authored-By: Claude Opus 5.5
