- Protocol: AgentFnResult = string | { output, childThread }, RoleOutput.childThread,
ThreadContext.bundleHash for parent state lookup
- Runtime: create-workflow normalizes AgentFnResult, propagates childThread in RoleOutput
- Engine: ExecuteThreadOptions.parentStateHash, appendStateForStep writes childThread,
putStartNode uses parentStateHash
- workflowAsAgent: reads parent head state from threads.json, passes parentStateHash
to child, returns { output, childThread: rootHash }
- Integration test: 4 cases verifying bidirectional Merkle links (306 lines)
Phase 2 of #194 (Merkle Call Stack). Closes #196.

@uncaged/workflow-execute
Thread engine: execution, fork/GC, extract pipeline, supervisor/worker wiring, and workflow-as-agent.
What This Package Does
It runs WorkflowFn generators against disk-backed threads, integrates CAS and registry-backed extract (createExtract), coordinates LLM tool usage via @uncaged/workflow-reactor, handles fork plans and garbage collection, and exposes workflowAsAgent for nesting workflows.

@uncaged/workflow-reactor is used for LLM-backed extract and supervisor flows (extract-fn.ts, supervisor.ts).
Usage
import { executeThread } from "@uncaged/workflow-execute";
// Typical callers are CLI/tests that supply ExecuteThreadIo (paths, CAS, abort, logger, …).
