Order is now: reveal -> trigger zone -> resolve effects -> hand (drive check) or damage (damage check). Damage is added only after the trigger resolves, so heal compares the pre-damage count. Temporary power/crit are cleared at end of turn instead of end of battle.
Damage check now places the card, then pauses on a trigger with PendingTrigger(DamageCheck) and the remaining damage count. Resolving applies the same +5000 and secondary effect as drive check, then continues the remaining damage or closes the battle. 34 tests.
Drive check now pauses on a trigger and waits for ResolveTriggerCommand(powerTarget, effectTarget). Power and crit modifiers moved from the battle to the unit and are cleared at the end of the battle. Stand stands the chosen rear-guard; Critical applies +1 crit to the chosen unit. Damage-check triggers still apply only the secondary effect.
Pure rules library with no Orleans or database. Command in, events out. Deterministic RNG stored in GameState. Covers setup with starting vanguard and mulligan, six phases, ride, call, attack, guard, drive check, damage check with triggers, retirement and win at six damage. 8 engine tests, 30 total. Sentinel, boost and card abilities are the next step.
