From d3ad243c4ae3a273f623bd5fc631e3266aa4d0e4 Mon Sep 17 00:00:00 2001 From: Christophe Besson Date: Wed, 30 Sep 2026 11:49:56 +0200 Subject: fix: only the owner decides who hosts a group, and nobody is made a member unasked MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - 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.
