Diagnose Why Work Stopped

Use Fix Failed Paperclip Run. It owns the current workflow: find the first causal failure, reproduce it red, repair the shared contract, test second-order effects, verify the real workflow, and deliver a PR with passing checks. A normal request to fix stopped work continues through that workflow without a separate plan-approval gate.

If the user or calling workflow explicitly asks for diagnosis only or requires approval before implementation, perform the investigation and safety analysis within that scope. For example, a Terminal-Bench diagnosis child does not override the loop's board approval boundary. Keep the next action and its owner explicit.

For issue-tree diagnosis, read the current doc/execution-semantics.md, inspect the relevant subtree and recent repairs, and classify non-progressing nodes:

• Genuine wait: a named human or external dependency must act.
• Agent-actionable but unrouted: authorized useful work lacks a live path.
• Already covered: existing work owns the next action; do not duplicate it.

Preserve these three invariants together:

1. Productive work has a real next action and owner.
2. Only genuine blockers stop work, including approval, credentials, and budget.
3. Recovery is bounded and cannot recursively recover itself.

Frame any repair as a general behavioral contract, check it against a productive counterexample, and follow the new skill through the authorized finish line. Historical task links and private incident access are not required.
