Phase 31 — The Roll and the Read
What changed
the combat momentum wheel moved from a mobile-side state splice into the engine (advanceMomentumWheel, gated on a landed card-played event); a new THE STAKE action lets the player wager 2/4/6 Conviction post-draft on the enemy's hidden stance, settling at the top of resolveThreatPhase into a floating-die mint (win) or an escalation-clock penalty (loss); and sig-conviction-strike was repriced 7→8 Conviction after a 540-run stage matrix showed it took 83.6% of all signature casts, crowding out sig-overwhelming-argument at the same affordability threshold.
Why it changed
closes build-plan Phase 31 (bundled per 01_build_plan.md's row, issue #82) and, as a side effect of reusing the floating-die pool for the wheel-granted die, likely fixes the standing HIGH plan/CRITIQUE.md finding that the wheel's forged wild die couldn't be dragged onto any card and silently burned as a spare — worth a /iterate confirm-and-drain pass.
