An unallied player holding CHOAM Nexus while CHOAM is absent can now discard one Worthless card during Spice Collection for two bank spice. The server spends both physical cards once, exposes only private legal card choices, and persists an already-paid discard receipt. Human controls and all four AI profiles share the action. The after-victory inspection alternative remains missing; normal unfinished modes and publication stay gated.
Independent review caught and fixed a queued Grumman Collection lock mismatch. Focused tests cover Basic/Advanced, actual card custody, private controls, all AI profiles, stale and wrong-mode rejection, Truthtrance and Grumman locks, JSON corruption/replay, competing production SQLite writes and private seat restoration.
A separate bounded acquisition helper recorded all seven Discovery Spice Cards, eight tokens and exact physical card placements from publisher-authored sources. Discovery runtime remains missing.

Efficiency counter: 59,982,405 at batch start; 60,581,959 after broad verification, delta 599,554 aggregate tokens before final preservation/Git/usage checks. One newly playable function plus the acquired Discovery inventory; this is not full CHOAM or Nexus compliance.

Preserve the optimized test workflow and keep unfinished rules modes gated. Verified with 3682 offline tests, typecheck, lint, production build and 40 HTTP tests; existing saved games remain unchanged.
