The 18-point triage path
Check an item only when you have observed it or recorded a clear exception. Preserve the original error and timestamp before changing state.
1. Establish scope
2. Validate the path
3. Collect evidence before repair
4. Decide and verify
Keep as evidence
Retain the original code, timestamps, comparison device, policy state, logs, action taken, and verification result.
Trust note
This runbook organizes investigation; it does not promise that every update error has one universal fix.
