Closes #892. Part of #853 (owner decisions 2026-10-24).

What changes, owner asks of 2026-10-24 00:32–00:45 Asia/Shanghai:

1. A group's invite link has no deadline and is not single-use. Anyone it is given to can join with their Bot until the owner withdraws it or the group is deleted. Needs Bot Social docs: complete social demo (add friend, held reply, approval, delivery) + MP4 #65 / A local room's link has no deadline and admits anyone it is given to, until withdrawn (#65) Birfy/bot-social#66 (merged, 929d390), which stores no deadline and keeps one claim per home.
   • Host (room-membership.js): a link records every home it seated (homes, read through homesOf; older records keep acceptedBy). Withdraw sets withdrawnAt: nobody new joins, the seats it made stay (owner decision on A local-room invite link cannot be redeemed by a home that cannot already reach the inviter (cross-repo: claim + connector exception) #853 point 3). A guest that leaves or is removed ends only its own home's claim at the server (endClaim); deleting the room revokes with endClaims. seatByTicket reads claimers and answers from the claim that brought the asker.
   • Members card: no countdown; "Works until you withdraw it."; copy "Anyone you give the link to can join with their Bot, until you withdraw it. They do not become a friend." A link an older server still dates keeps its countdown. When earlier links of the room are still open the row says how many and offers Withdraw all.
   • Joining side: a preview with claimed means this home already joined, said as such, never "someone else joined".
2. Members card layout. The Invite by link heading, description and button share the card's row padding; the button is vertically centred with the heading; the "Chief leads this group…" note sits with the members list again, above the invite section.
3. "Face-to-face room" → "Join or create by number or link" (zh 面对面建群或用链接加入): + menu label and hint, dialog title, description, link placeholder, en + zh.
4. A group joined by link keeps its name on the joining home (roomTitle): sidebar, header, drawer, brand show "Trip plan"; "Shared room from Ann" stays as the row's hover and the Shared tag's title. A friend-shared room with no link keeps today's title.

Plugin copy now goes through core's t() (__flybot__.t), so the zh UI reads the Members-card and dialog copy in Chinese.

Tests: TZ=UTC npm run verify exit 0 (core 1328, social 395, tree 125, timeline 125, scripts 332, interop 37, live-e2e 16). Rewritten: core/test/room-ticket-seat.test.js (fake server now multi-claim, no deadline; withdraw keeps the seat, removal ends that home's claim, room delete ends every home's), remote-room.test.js, social plugin tests for the row, the dialog and the new entry.

No CHANGELOG/version edit (fragment in changelog.d/). No risk label.

Verdict: PASS at dc8d5dd
Written-by: Reviewer

Focused review of the whole diff vs origin/main (c90af02), against the owner's asks of 2026-10-24 and Birfy/bot-social#66 (merged as 929d390):

• No deadline, not single-use: openInvite = not withdrawn and not dated out; a home that joined does not close the link (homes, older acceptedBy read through homesOf). A dated link from an older server keeps its countdown.
• Withdraw sets withdrawnAt, revokes at the server without endClaims, keeps the seats (owner decision on A local-room invite link cannot be redeemed by a home that cannot already reach the inviter (cross-repo: claim + connector exception) #853 point 3); the server's localPairClaim reads live claims, so the seated guest keeps its reach. Removal or leave ends only that home's claim (endClaim → DELETE /v1/local-room-invites/{t}/claims/{handle}, which the server resolves from a Bot handle); room delete revokes with end_claims=1.
• seatByTicket answers from the claim whose Bots include the asker and checks that claim's home against the transport sender.
• Members card: no countdown, new copy en+zh, earlier-links count with Withdraw all, lead note above the invite section, row padding shared. + menu entry and dialog reworded en+zh; plugin copy via __flybot__.t. roomTitle keeps a link room's own name.

Ran:

• TZ=UTC npm run verify at this head: exit 0; core 1328/1328, social 395/395, tree 125, timeline 125, scripts 332, interop 37, live-e2e 16.
• Knife: made openInvite close a link once any home joined (&& !seatedBy(invite)), ran core/test/room-ticket-seat.test.js + remote-room.test.js: 60 pass, 2 fail; restored.
• Live two-home run (not friends) installed from GitHub at this head, Bot Social master 929d390, fresh data: mint answered expiresAt: null; B previewed ("Trip plan", lead Chief, owner Ann, claimed false), joined with Scoutb; A's group shows Scoutb (admittedBy ticket); B's sidebar row reads "Trip plan"; lines Ann→Ben and Ben→Ann both arrived.
• gh pr checks 893: tests-ok and ubuntu-latest · Node 24 · DSH 0.2.0-rc.2 green at this head.

Notes (non-blocking): a second stranger home on the same link is covered by the unit tests, not the live run.
