Connect expansion faction setup and saved Ixian auction decline

Add a local faction-only prototype profile for all seven nonempty expansion selections, genuine Basic/Advanced initialization and existing private setup, controls, AI and saved continuation. Ecaz allocates six forces across Imperial Basin sectors and retains fourteen reserves before later setup; preserve Fremen, Advanced BG and Moritani ordering with printed and inferred boundaries explicit. Keep optional Ecaz Treachery cards separate, ordinary deck counts 33/35/47, and Richese cache separate. Public start and publication gates remain closed.

Replace the Advanced Ixian/Richese pre-offer stop with an explicit per-lot Ixian decline. Bind the saved original offer to its round, turn, owner, independent event, exact card custody and terms before view/action/normalization. Decline resumes that unchanged lot once without using Technology; later normal lots still offer the exchange. Protect reserved cards across transfers, spending and random Harkonnen exchange, and preserve legitimate Gift/Truthtrance interruptions. The actual special-lot exchange still awaits replacement-custody interpretation.

Validation: focused setup, rules, UI/bot, private JSON/SQLite reload and concurrent CAS tests and independent custody/persistence review passed. Typecheck, lint, 4573 offline tests, production build and 43 HTTP tests passed. Browser Ecaz setup rejected an incomplete total, saved a 2/2/2 split, and refreshed to fourteen reserves and unchanged private cards. A separate genuine Advanced QA game restored the Ixian choice; explicit decline opened the unchanged cache lot with legal bidding and retained private hand, spice, pool count and unused Technology after refresh.

Five of six genuine four-profile samples finish: CHOAM Basic 1054 actions/28 JSON restores, CHOAM Advanced 225/6, Ecaz Basic 91/2, Ecaz Advanced 523/14, all-three Basic 476/12. Combined Advanced passes three former auction stops and reaches turn three/action614 with 16 restores, then hits an existing CHOAM movement/Ambassador arrival guard. Ecaz samples also include guarded arrival candidates with legal alternatives. Full combined play is not certified; arrival integration is the next gap. Retain initial failed logs, including a corrected private harness sold-card receipt alias.

After the outage, all 597 opening rooms and original seat/recovery records were preserved (632 after QA/HTTP). A stale development module cache required restart after a fresh 598-room backup; all 598 matched afterward and the QA seat restored. Final integrity and foreign keys passed. No database reset, recurring automation or publication.
