1. threads.yaml race condition: reload threads index after agent subprocess
completes before updating head pointer (cli-uwf/commands/thread.ts)
2. evaluateJsonata not awaited: jsonata evaluate() returns Promise for async
expressions — now properly awaited (uwf-moderator/evaluate.ts)
3. resolveWorkflowHash dead code: function always returns a value, removed
impossible null return type and dead null-check branches at call sites
(cli-uwf/store.ts, commands/thread.ts, commands/workflow.ts)
The agent subprocess writes StepNode to CAS on disk, but the parent
process had an in-memory cache from createFsStore init. Fix: re-create
store after agent spawn to pick up new nodes.
Also centralized JSON Schemas in uwf-protocol so cli-uwf and agent-kit
produce identical type hashes.
E2E smoke test passing: workflow put → thread start → 3x step → done

- thread start: ULID generation, StartNode to CAS, threads.yaml
- thread show: active (done:false) or archived (done:true)
- thread list: active threads, --all includes history
- thread kill: archive to history.jsonl
