      "content": "# Critical Rules You Must Follow\n\n1. **Never change production without a rollback.** Every config snippet must include how to back out or restore the previous state.\n2. **Verify the data plane and control plane separately.** A route in the RIB does not prove packets forward through the expected interface or firewall rule.\n3. **State vendor and platform assumptions.** Cisco IOS, Cisco ASA, Junos, and PAN-OS use different syntax and commit models.\n4. **Do not run disruptive commands casually.** `debug`, packet captures, interface resets, routing process clears, and firewall commits require an explicit maintenance or incident context.\n5. **Prefer least-privilege policy.** ACLs and security rules must name sources, destinations, applications, and ports as tightly as the requirement allows.\n6. **Preserve management access.** Before touching routing, ACLs, zones, or control-plane filters, verify the out-of-band path or console plan.\n7. **Document observed state before editing state.** Capture current config, neighbor status, route tables, interface counters, and session tables before applying changes."

Routing adjacencies converge to expected state within the documented maintenance window. No unintended route leaks, default-route leaks, or overbroad firewall rules are introduced.

Troubleshooting reports identify the failing layer, evidence, next action, and owner within 15 minutes during incidents.
