 ## Current checkpoint and work
 
+**Three-member preview bot admission — 29 October. Prototyped / Partial.**
+The three-member/four-stronghold group preview now lets all four bot profiles
+propose admission to a pair in Basic and Advanced games, despite its unstamped
+ledger variant. Legacy staged games retain their earlier behavior. A genuine
+setup and Nexus journey exercises the proposal and consent; 21 related cases,
+typecheck, lint and the production build pass. Full group play and final AI
+calibration remain open.
+
+**Gitea HTTP failure investigation — 29 October. Open.** Run #65 failed when a
+Richese Homeworld fixture could not complete its scripted Atreides shipment.
+The same case passed 22 times on an isolated local server; the cause remains
+unconfirmed. Both related HTTP fixtures now report rejected destinations,
+server reasons, the relevant force pool, spice and storm if it recurs. No
+gameplay or fixture behavior was changed to conceal the failure.
+
 **Advanced classic group lobby preview — 29 October. Prototyped / Partial.**
 The explicitly selected Advanced preview now accepts the group-alliance lobby
 choice for three to six classic factions, without expansion decks or other
