Feat/automation condition action nodes - #9
Merged
Conversation
Adds SDK support for plugins to register Condition and Action automation-graph node handlers, alongside the existing event handlers. - automation.go: ConditionRequest/ConditionResult, ActionRequest/ ActionResult (with NodeType + TaskSnapshot), and the marshal helpers used by both the WASM and native dispatch paths. - context.go: Context.Condition(nodeType, handler) and Context.Action(nodeType, handler) registration API, mirroring the existing Context.Event(topic, handler) pattern. - dispatch.go: dispatcher.evaluateCondition/runAction deserialize the host payload (now including node_type - see the paired paca core change) and route to the handler registered for that node type. - wasm_exports.go: EvaluateCondition/RunAction wasmexport functions, using the same (ptr,len)->int64 packed-pointer calling convention as the existing HandleRequest export (confirmed against the host runtime's callExport in paca core's platform/plugin/runtime.go). - testing.go + plugintest/plugintest.go: DispatchCondition/ DispatchAction native-test helpers, and Context.EvaluateCondition/ Context.RunAction test-harness methods for plugin unit tests. Verified: go build/vet/test clean (native), GOOS=wasip1 GOARCH=wasm go build clean.
