- Condition parse cache: each unique string parsed once (Map<string, ParsedCondition>)
- executeAction: throw on missing type/malformed action/missing action; warn-only on
destroyed entity (legitimate mid-flight case)
- World.query() overloads for 2 and 3 component types: query(A, B) → [Entity, A, B]
- World.once()/off() consistency: #onceWrappers map lets off(event, original) correctly
remove handlers registered via once()
- World.cloneEntity(source, newId?): deep-clones all components via structuredClone,
onAdd() fires normally on the new entity
- isEntityContext() type guard alongside isEvalContext()
- Inventory.getVariables() cache: invalidated on add()/remove()
- QuestLog.getVariables() cache: invalidated on any status transition or _advance()
- QuestLog.entries() explicit Generator return type
- Variables JSDoc: clarifies when to use Variables vs typed Component<TState>
- @component({ name?, version? }) object overload in registry
- registerMigration(name, from, to, fn): chained migrations run automatically on
deserialize when saved version < current version
- Serialization wire format: ComponentData carries version, WorldData carries
schemaVersion; mismatched schemaVersion throws a descriptive error
