    "summary": "Terminal Output Panel Canonical is the memory of operational execution, not a visual terminal clone. Its job is to make command results durable enough for validation, rollback, learning and operator review after the command scrolls away.",

Patch Outcome Tracker needs this panel to decide whether a patch actually changed state. Test & Validation Runner needs it to prove PASS or FAIL without relying on screenshots or summary language.",
