## Unreleased

- Built-in `Goto` step and early `Return` control flow.
- Closure-backed conditions and effects, with constructor shorthands for

- Whole-library validation, library name lookup, and nested authoring
  warnings.
- `StepFacts::references` exposes every outgoing sequence reference to

  zero-capacity event buffering.
