 # @typeonce/effect-machine
 
+## 0.4.0
+
+### Minor Changes
+
+- d02dacb: Add an Effect-native `@typeonce/effect-machine/testing` entrypoint with schema-derived scenarios, replayable planner traces, independent statechart law and finite-model verification for compound, parallel, and history states, trace coverage, observed Effect graphs, and live runtime command models.
+
+  Expose retained planner transition evidence and correct reentry boundaries, simultaneous parallel target application, and recorded nested-history restoration through inactive ancestors.
+
+- 6809080: Add public getters for inspecting compiled state nodes, registered transition handlers, declared transition targets, and the active state configuration of a snapshot. Event, eventless, and completion handlers may declare an upper bound of target paths that is checked against inferred and runtime results.
+- 2e45e12: Expose a captured full machine snapshot to event, eventless, and completion transition contexts; add serializable state-owned activity inspection for invokes, timers, and child machines; and surface resolved Effect Schema annotations plus descriptive pseudo-state annotations through state-node inspection.
+- 1312de1: Add first-class, type-safe choice pseudo-states with Effectful resolvers,
+  inspectable target bounds, stable-snapshot exclusion, and MachineTest trace,
+  coverage, verification, generated-model, and reference-model support.
+
+### Patch Changes
+
+- 5656f41: Fix first-use nested history defaults by requiring a complete source-independent configuration containing the history owner and using it to rebuild inactive compound and parallel ancestors.
