blackbox 0.3.0

Deterministic reactive computation core with explicit dependency graphs, boxes, and flows. Designed for testable business logic and state pipelines.

0.3.0

• Breaking:
  • when() loading callback signature: () → R → (T? previousData) → R
  • when() error callback signature: (Object, StackTrace?) → R → (Object, StackTrace?, T? previousData) → R
• Added:
  • AsyncLoading.previousData — carries last known value during refresh
  • AsyncError.previousData — carries last known value on error after refresh

0.2.0

• Breaking:
  • Removed LazyBox — use persistKey parameter on Box/AsyncBox constructors
  • Removed computeValue() — NoInputBox and NoInputAsyncBox now use compute() directly
  • Renamed dependencies: parameter to input: in Graph.add()
  • Renamed d.ready() to d.whenReady() in DependencyResolver
  • Removed d.output() from DependencyResolver (use box.output directly)
  • Removed public input getter from Box/AsyncBox
• Added:
  • prepare(I input, O? previous) lifecycle hook — called once before first compute
  • dispose() lifecycle hook — called by Graph.dispose() for resource cleanup
  • persistKey parameter on Box/AsyncBox constructors for built-in persistence
  • BlackboxPersistence.registerCodec<T>() for global codec registry
  • Graph signal tracing: build(trace: true) for console output, onTrace: for custom handler
  • PumpTrace / BoxTrace data classes for programmatic trace access
• Changed:
  • Box hierarchy refactored: shared _SyncBoxBase/_AsyncBoxBase internal base classes
  • NoInputBox<O> and NoInputAsyncBox<O> are now independent from Box<I,O> / AsyncBox<I,O> (both extend shared base)
  • All box types use compute() as the override method name

0.1.0

• Breaking:
  • Connector -> Graph
  • ConnectorBuilder -> GraphBuilder
  • connect(...) -> add(...)
  • connectWith(...) -> addWith(...)
  • PipelineBuilder.addWithDependencies(...) -> addWith(...)
  • FlowBoxBuilder() is now created via FlowBox.builder()
• Changed:
  • Updated docs, tests, and examples to the new graph/flow builder API

0.0.7

• Renamed:
  • StateObserver -> FlowBox
• Breaking:
  • FlowBox<S> now requires S extends FlowState
• Added:
  • FlowBoxBuilder.onLoading(...) and onError(...) for reacting to AsyncLoading and AsyncError
• Changed:
  • FlowBox is now a sync box without input (Box<O>)
  • onLoading(...) and onError(...) are compile-time restricted to async sources only

0.0.4

• Renamed:
  • Graph -> Connector
  • Flow -> StateObserver

0.0.3

• Added GraphBuilder
• Added Pipeline of Boxes

0.0.2

• Updated docs

0.0.1

• Initial release
