Run inert captured-script analysis in owned children with per-script and aggregate deadlines, bounded source/result transfer and explicit per-script coverage. Preserve completed facts and exact cleanup authority across cancellation, mixed descriptor/process failures and cross-consumer retry. Share aggregate source admission across page and Electron capture, expose CLI/MCP resource controls and retain selected parameters in Evidence. Verified with controlled CDP public workflows, real owned Node failure controls and the reporter-matching ReactDOM UMD artifact; real Chrome/Electron and Windows/Bun remain unqualified.
