DAMAGE_DEALT fires for a different demon (not Vapula) — passive silent.

Preconditions

• Lane 0: P1's Vapula (#100) — READIED

• Lane 0: P1's Murmur (#002) — READIED

• Lane 0: P2's Duban (#001) — 5 damage

Action

• Fire DAMAGE_DEALT with source=Murmur -> Duban, value=3

Expected Postconditions

• Duban damage unchanged (Vapula does not trigger for Murmur's damage)

Assertions

assert duban_after.damage == 5, (
            f"Vapula passive must not fire for Murmur's damage. Got {duban_after.damage}."
        )
