fix(hub): Search reaches each group with one offer, and a busy hub is not a dead node

2026-09-23T22:10:41Z

The other half of the 4G failure. The page negotiated every group twice: the sweep opened a connection, read the index and closed it, then the warm-up opened the same group again. The sweep, the warm-up and the tiles each had a concurrency ceiling of their own, and together they went past what the hub admits per account. Whatever the hub refused was then reported as "node unreachable" and remembered as down, which put that group last next time. - Every connection goes through ConnectionPool, which holds the page's one ceiling (six at once, sized for twenty groups on a phone) and keeps what the sweep opened for the tiles. A visit costs one offer per group. A refresh costs none for a connection that answers a four-second ping, and a connection that died while the phone slept is replaced, not waited on. - A connection whose index is being read is held against eviction. With more groups than the pool keeps, it was otherwise the least recently used one. - Negotiations still under way when the page closes close what they get, and a sweep cut short that way remembers nobody as down. - transport.js sends an offer again on 429, 502 or 503, honouring Retry-After, with jittered waits of about twenty seconds at worst. Search counts each retry as progress. A 404, 403 or 504 still fails at once, so a dead node costs no time. The fan-out tests assumed a ceiling of three and were re-measured: four dead groups of twelve now hold nothing back, even on a first visit. The pool and the retry run as shipped code, lifted as text, against a fake clock. Each guard was checked by removing it and seeing its test fail. Co-Authored-By: Claude Opus 5.5

fix(hub): offer ceilings that bound a member without failing an ordinary one

2026-09-23T22:10:41Z

A phone on 4G found one of five groups missing from Search on half its visits, and all but one on a fifth of them. Every offer that reached the node was answered in about a second; the hub refused the others with 429 — 93 of them in half an hour on meshbay.org, all from that phone, all to nodes that were up. Two ceilings did it. Three pending offers per account was exactly what one Search page dialled at once, so the first tile or reconnection beside the sweep was refused. Thirty offers a minute per address and per node was spent by four or five reloads of a page whose groups share one node. Sized now against an account with twenty groups on three devices: - 32 offers pending per account, across devices and nodes. - A budget per account and per node, a burst of 120 refilled at two a second. This is what bounds a member's cost to one machine (H6), and it leaves their other nodes alone. Counted by account, because a mobile carrier puts many subscribers behind one IPv4 address. - 600 a minute per address and per node, as a coarse guard in front of authentication only. Both refusals carry Retry-After, which the browser now honours. The node's own ceiling on peer sessions is unchanged; its comment no longer quotes the old per-account number.

fix(hub): a redeemed invitation link leaves the owner's list

2026-09-23T17:30:47Z

The list under "Invite by link" answered every ticket the group had ever minted, so a link that somebody had already used sat there saying "used by " for the thirty days of KEEP_REDEEMED — beside the member row it had just produced, and above the links that still wait for somebody, which are the only ones there is anything to do about. The node's own `member list` had never shown them: it selects `used_at IS NULL`. The listing now selects `redeemed_by IS NULL`, and drops the `redeemed` status and the `redeemed_by` field with it. The row itself still lives for KEEP_REDEEMED, which is what lets a reload or a second tab of the invitation page be answered rather than refused; its comment says that now instead of naming a list it is no longer in. The SPA filters too, because the desktop client's copy of this interface can be newer than the hub it is signed into. Co-Authored-By: Claude Opus 5

fix(client): let Copy buttons write the clipboard in the desktop app

2026-09-23T17:01:37Z

Only fullscreen was granted, so navigator.clipboard.writeText was refused and every Copy button did nothing. Grant clipboard-sanitized-write; reading stays refused. Co-Authored-By: Claude Opus 5.5

fix(hub): an invitation no longer holds back its invitee's sign-up code

2026-09-23T17:01:37Z

The per-recipient cooldown was shared by every purpose, so the code a person asked for by registering within two minutes of an invitation link was refused, silently. The cooldown is now per family (invitations vs the account's own steps); the daily cap still counts everything. Co-Authored-By: Claude Opus 5.5

docs: qualify what an invitation link changes about the code

2026-09-23T16:16:44Z

The security claims table, §3.4's property 2, the protocol's stated limits, the quickstart and the user guide's defaults now say where a link's code differs: bound to its account only when redeemed, and held by the hub when the inviter asks it to mail. Co-Authored-By: Claude Opus 5.5

feat(node): member invite --link and member cancel in the CLI

2026-09-23T16:16:02Z

The CLI makes both halves itself — the node's code, then the hub's ticket bound to the address — and prints the link; a refused ticket takes the code back, and cancel takes back both. The CLI never asks the hub to mail. Co-Authored-By: Claude Opus 5.5

feat(hub): open, create and join invitation links in the interface

2026-09-23T16:05:14Z

#/invite takes the link out of the address on load and keeps it in the tab through registration and sign-in; joining is one click, only the ticket goes to the hub, and the code goes only to the node the link names once it has signed its challenge. Members tab gains "Invite by link" (shared e-mail box, pending list, cancel both halves); home page takes a pasted link. Browser probe drives the real app, signed out and in.

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

docs: drop the invitation-link plan from the tree

2026-09-23T15:46:48Z

The plan was a working document; what it decided lives in MESHBAY_DESIGN.md and MESHBAY_NODE_PROTOCOL.md. Code and tests now cite those instead. Co-Authored-By: Claude Opus 5.5
