Widen computeCrossParentDiagnosticClaim so repair tasks phrased as 'exceeds limit / oversized / blocking X / so X passes' converge on a file-path or distinctive-slug anchor at creation time (FN-8510/8511/ 8513/8514 incident: four executors on unrelated parents filed the same oversized-changeset follow-up and none deduped before triage). Add a Provenance section to the Task Detail Stats tab showing source type, parent task, creating agent, imported-issue link, and the triage near-duplicate marker.
