Routing rots because orgs change faster than configs. The senior answer treats ownership as data resolved from a catalog at fire time, with drift detection on the routing itself.

The expensive part of these incidents is almost never the fix. It is the twenty minutes spent deciding whose incident it is.

Assess a requested control bypass against its purpose and approval rules, then propose a permitted delivery path and document the actual decision.

Assess a signed vendor choice against the actual requirements and contract, then support a bounded implementation or raise material new evidence through its owners.
