fix(work-item-pipeline): carry owner identity into finalize step across engine threads

[getappz]

Problem

In-process work-item dispatch (item #19) fails at finalize with:

finalize: item <id> is claimed by 'opencode:<job_id>' (active Ns ago) —
refusing to complete someone else's live claim

Root cause

WorkItemExecutor::execute sets the claim owner via with_owner_override("opencode:<job_id>", …), a thread-local (OWNER_OVERRIDE in claims.rs). That override is set on the worker-pool thread where item_claim runs, so the claim is correctly acquired as opencode:<job_id>.

But the workflow engine runs steps on WORKFLOW_RT — a separate multi-threaded tokio runtime (new_multi_thread().worker_threads(2)). finalize's item_done executes on an engine worker thread where the thread-local override is absent, so owner_id() falls back to the daemon's ambient env identity (cli:<pid>). item_done then sees its own live claim as someone else's and refuses to complete it.

Not a duplicate dispatch — the same job's claim, misattributed across threads. The old subprocess path set AGENTFLARE_AGENT process-wide so every thread resolved correctly; the in-process migration swapped that for a thread-local that only covers the caller thread.

Fix

• run_or_resume_with_sender captures owner_id() on the caller thread (override still active) before block_on.
• Thread it into build_finalize_step, which now wraps its body in with_owner_override(owner, …) so item_done/item_release/comment_impl resolve the correct identity regardless of thread.

Summary by CodeRabbit

• Bug Fixes
  • Improved workflow finalization so actions consistently retain the correct owner identity.
  • Ensured hold, human-review, and successful completion paths continue to process items, comments, notifications, and retries reliably.
  • Improved consistency for workflows started during application boot.

📝 Walkthrough

Walkthrough

The pipeline now captures the claim owner before workflow execution, passes it through pipeline construction, and applies it during finalization. Finalization preserves existing hold, review, completion, notification, and retry behavior.

Changes

Claim owner finalization

Layer / File(s)	Summary
Capture and wire the explicit owner src/work_item_pipeline.rs, src/dashboard/server.rs	Pipeline builders accept and forward an explicit owner. Workflow execution captures the owner before worker-thread execution. Boot-time construction supplies the new argument.
Execute finalization under the owner src/work_item_pipeline.rs	Finalization wraps hold, human-review, completion, comment, and notification operations in claims::with_owner_override. Tests provide the owner argument.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 9a42a

The PR fixes owner propagation for finalize operations; only a trivial documentation clarification remains, so no actionable merge-blocking risk remains.

Document the placeholder owner in the existing comment.

The block comment above explains the empty item id but not the new empty owner. claims::with_owner_override("") sets the override without an emptiness filter, so a resumed dummy run resolves the owner to "" instead of the daemon identity. The run still fails closed on the empty item id, so behavior is safe. Add one line so the placeholder rationale stays complete.

📝 Suggested comment addition

     // enough (item id, agent, prompts) for these steps to rebuild their own
     // `AgentflareMcp`/request at execution time instead of capturing one at
     // registration time — tracked as follow-up, not attempted here.
+    //
+    // The empty owner below is part of that same placeholder identity:
+    // `finalize` scopes claim actions to it, but the empty item id already
+    // fails those calls first, so no real item is ever touched under it.
