The Agent Guarded One Caller and Left the Same Bug Behind the Other Door

Two separate incidents highlight failures in AI agent updates. In the first case, a patch for a null field was applied to a user-facing path but missed an internal batch job, causing a crash. In the second instance, an agent renamed a service class across the symbol graph and tests, yet left the old name within an error string. This led to a support engineer wasting an hour searching for a non-existent component.
