+**Prototyped / Partial.** When sealing Reinforcements, its owner can select any

+Homeworlds the owner also selects valid native source allocations for that mix;

-The holder must have three own reserve counters when sealing the plan. The owner-only battle offer displays availability and the exact provisional cost. The current prototype deterministically takes ordinary reserves first, then elite reserves if needed, transferring precisely three physical counters to the corresponding Tanks subpools when the battle settles. There is no spice payment or on-board arrival. The +2 changes the calculated normal-outcome battle score, **not** the committed physical dial, support payment, casualty count or leader survival. The card is discarded after any revealed result, including an own, opposing or mutual Traitor call and Lasgun/Shield explosion. The cost is likewise paid on each of those outcomes. A successful Traitor call still supersedes the normal score; the modifier never overrides it. Public history records the transfer; the sealed card and owner reserve mix stay private until the reveal. JSON-restored decisions and transactional room updates cannot charge the same cost twice.

-**Provisional interpretations, not publisher rulings:** The card says “increase the dialed number by 2” and transfer three reserves, but no retrieved combined ruling answers whether a sole successful Traitor caller instead keeps their reserves, how the transfer orders against an explosion, whether +2 adds Advanced support or physical losses, which reserve types the holder may select, or whether the three spent reserves count as battle losses for Atreides. For this bounded prototype, payment is at battle settlement before on-board casualties on every outcome; the engine counts the three as battle losses, chooses normal-first rather than offering a type selection, and keeps the score bonus separate from physical dial.

 The owner receives a card-slot explanation and disabled reason when fewer than three reserve counters remain or the bounded mode is unsupported. All four AI profiles generate legal candidates in the classic and Ecaz/Moritani profiles and can select either slot, including an Advanced plan. The current scoring is a minimal legal participation heuristic, not difficulty calibration. The prototype does not certify the whole three-card variant, other expansion combinations, optional modules, historical-save compatibility or public mode starts.
