Tutorial advanced

Eight chapters on the features that make japes' scheduler hum — events, per-system state, stage ordering, multi-threading, archetype narrowing, and the escape hatches (@Where, @Exclusive, @RunCondition) for when the common path isn't enough.

#	Chapter	Topic
9	Events	EventReader<E> / EventWriter<E>
10	Local<T>	Per-system persistent mutable state
11	Stages and ordering	before / after, default stage names
12	Multi-threading	Executors.multiThreaded(), disjoint-access parallelism
13	Query filters — @With / @Without	Archetype narrowing without binding
14	Field filters — @Where	Per-entity value predicates
15	@Exclusive systems	Single-threaded bulk edits
16	Run conditions	@RunCondition / @RunIf for gating

Chapters are mostly independent; pick what you need. The only hard dependency is that multi-threading assumes you understand Commands from the basics section.
