 Custom modifier descriptors compose **trigger primitives** that wire nested effect primitives into specific points of the engine's per-move dispatch. Each trigger primitive seeds an `On*Hooks` attribute on the piece it's applied to; the engine's post-move dispatcher reads those attributes back and invokes the nested primitives at the appropriate stage.
 
-This section documents the **11 trigger primitives** (4 existing + 7 added in Wave 2), the order in which the engine fires them, and the `PrimitiveApplyContext` extensions (target redirection + event payload) that nested primitives can read.
