7. Commit Abilities into Effects

Commitment is the point where an active ability crosses the caller-defined point of no return. Flexweave does not define that as "pay cost" or "start cooldown"; the runtime decides what commitment does.

In the RPG example, commitment:

• spends mana
• applies ability-specific cooldown effects
• turns Slash into an instant damage effect
• turns Quickened Strikes and Fortify into duration effects

Ability-specific commit behavior lives with the ability, not in one central match over every ability payload.

impl AbilityCommitAction<CombatState, CombatTags, AbilityPayload> for CombatCommit {
    type Error = CombatError;

    fn apply_commit(
        &mut self,
        state: &mut CombatState,
        active: ActiveAbilityView<'_, CombatTags, AbilityPayload>,
    ) -> Result<(), Self::Error> {
        active
            .payload
            .commit(state, active.source_id(), active.owner_id)
    }
}

For example, abilities/slash.rs owns the Slash effect application, while abilities/quickened_strikes.rs owns the attack-speed buff and cooldown.

If commit fails, Flexweave rolls back active ability state according to the ability lifecycle contract.
