ADR 029: Initiative System Refinement

Status

Accepted

Context

The initiative system needs to handle ties robustly and be extensible for variant rules (e.g., Speed Factor Initiative).

Decision

We will extract the initiative sorting logic into an IInitiativeComparer strategy.

• Interface: IInitiativeComparer : IComparer<InitiativeRoll>
• Standard Implementation: StandardInitiativeComparer sorts by:
  1. Total Roll (Descending)
  2. Dexterity Score (Descending)
  3. Random/Deterministic Tie-Breaker (e.g., Creature ID)

Consequences

• Positive: Decouples sorting logic from the Turn Manager. Allows easy swapping of initiative rules.
• Negative: Adds a small amount of complexity (dependency injection).
