The deployed A.3 join signs with the current key, which a later responder commit can orphan; a conforming peer defers the reciprocal A.5 until the peer's own A.5 has landed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A follow-up to #148: this commit landed after that PR merged.
Spec (Group Rules rule 4, and the A.3 step): until a leaf moves, its owner signs in that group with the key the leaf presents. A group joined from the A.3 KP′ is signed with KP′'s key, even if the owner rotated after minting it. Moving one group's leaf never retires a key that another group's leaf still presents.
Shipped anomalies: they're now collected in one "Shipped anomalies" section at the end of Session Lifecycle, linked from the catch-up text, the A.3 host paragraph and Protocol Flows. There are six numbered deviations, each with its resolution nested beneath it:
Welcome'completes A.3 because the deployed initiator binds and its bind rides an ordinary frame. Later A.4 and A.5 rounds stay open until the deployed party upgrades; re-send cadence is host policy, and a host never drops the parked leg. No protocol change.Book-only, with an empty changeset.
