+## 27 September 2026 — CHOAM/Richese and Ecaz/Moritani roster samples
+
+The [sample runner](VERIFICATION_WORKFLOW.md#reusable-base-and-faction-sample-games) now covers each expansion pair in Basic and Advanced at two through six seats, using genuine faction setup, legal AI decisions and periodic JSON restoration. The ten CHOAM/Richese games at seed 20260928 and ten Ecaz/Moritani games at seed 20260927 completed: 6,523 accepted actions, 167 restores, no rejected actions. Source-bound checkpoint reports are `/tmp/dune-choam-roster-checkpoint-20260928/report.json` and `/tmp/dune-ecaz-roster-checkpoint-20260927/report.json`. A separate CHOAM/Richese seed 20260927 completed nine games but stopped in six-seat Advanced Bidding after 1,728 accepted actions: an exhausted Richese cache reached the existing explicit unresolved normal-auction-count guard. That source question remains open, not papered over by the passing matrix. These samples do not certify full expansion rules, all rosters or public starts.

 ## 27 September 2026 — Bounded CHOAM Nexus Betrayal
 
 The [CHOAM Betrayal panel](NEXUS_CARD_RULES.md#bounded-choam-betrayal-runtime) now has a playable Basic/Advanced path when CHOAM is seated. An unallied rival spends the physical CHOAM Nexus card at a clean boundary; the server samples and discards one actual held CHOAM Treachery Card without spice compensation. The holder-only control never offers a rival card choice or identities; its hand count appears only during Bidding. Bots act only when that count is public. A saved discard receipt completes once after JSON restore, including later same-turn Nexus recycling. Focused quote, controls, bot, physical inventory, rejection and interruption cases pass; the isolated browser table rendered the enabled holder control without room writes. Complete Nexus, combined-module and deployed revision acceptance remain open.

 Default and `--profile all` retain the original six fixed CHOAM/Richese,
 Ecaz/Moritani and combined Basic/Advanced samples. `--profile base` selects ten
 additional samples: Basic and Advanced with two through six players.
-`--players 2..6` narrows the base, Homeworld, Nexus or combined
-`homeworld-nexus` profile; omission or `all` retains all five counts. The fixed
-base roster adds Atreides, Harkonnen, Fremen, Emperor, Guild and Bene
-Gesserit in that order. These are sample rosters, not an assertion that these
-are the only rules-permitted player-count configurations. Each optional
-module profile runs two through six base factions under Basic and Advanced
-using the actual setup seams. Output names include the player count.
-Homeworld's original four-seat seed offsets remain 36–37; its other rosters
-use 48–51 and 54–57. Nexus's six-seat offsets remain 38–39; its smaller
-rosters use 40–47. The combined module uses offsets 58–67. These samples
-do not open public module starts or assert complete module interaction

 All-AI Nexus samples now make public reciprocal offers as well as accepting
 them, so an actual alliance can form without a human proposer. At the
