 ## Current checkpoint and work
 
+**Staged joint group commitments — 29 October. Prototyped / Partial.**
+The joint planner can retain matching group membership or quote a member's own
+departure, including payment to a former ally after leaving. An invitation
+pauses joint reconciliation; compatible admission checks combined payment and
+travel costs against the same purse. Thirteen related files pass 58 cases,
+including real answers, admission, departure, payments and a constrained shared
+wallet. Typecheck, lint and the production build pass. Two older whole-turn
+affordability cases were corrected: in their fixture, an 11-spice payment can
+use an earlier payment and later Charity, while 13 cannot. Actual
+whole-turn group changes, member-commitment funding, other profiles and lobby
+entry remain unfinished. [Scope](OPTIONAL_ALLIANCE_VICTORY.md#group-admission-with-joint-commitments--29-october-2026).
