-### P3 — Member-issued / multi-bootstrap tickets — Small (the ticket mechanism)
-Let any current member mint a ticket from `{ their live addr, the session topic }`
-(both already in hand). Pre-exists: the type `PeerSpeakTicket` and `RoomState::join`
-already takes `extra_bootstrap: Vec<EndpointAddr>` (A8). Optionally bundle several
-present members for redundancy. Also tighten ticket encoding (drop JSON/base64 fat,
-index the relay URL — lossless, ~halves the string).
+### P3 — Member-issued / multi-bootstrap tickets — ✅ core DONE 2026-06-15 (`c90dcf7`)
+- **Member-issued ticket (DONE, non-breaking):** the ticket the UI shows/copies is
+  now stamped with the local member's own live address + the room's topic (pure
+  seam `PeerSpeakTicket::restamp`, +3 tests), so every member hands out a working
+  door pointing at themselves → rooms outlive their creator. Only the *display*
+  copy is re-stamped; the join/bootstrap `ticket_str` + A8 retain logic are
+  untouched. 248 lib tests green. ⚠️ **2-machine field test pending** (creator
+  leaves → a joiner's ticket still admits a newcomer).
+- **Deferred (both BREAKING wire changes — want daylight + 2-machine):**
+  multi-bootstrap ticket (bundle several present members as `extra_bootstrap`,
+  needs a ticket struct change) and tighter ticket encoding (drop JSON/base64 fat,
+  index the relay URL; lossless ~halving).
 
 ### P4 — Friends-only idle listener + presence — Medium (the new primitive)
 A long-lived endpoint while the app is open (own ALPN, e.g. `peerspeak/friends/0`),
