The strangest line may be holding back the oldest incident.
Odd code deserves investigation before deletion; context may have outlived its comment.
Interpretation
An unexplained sleep, duplicated condition, or special case may be accidental debris—or the remaining guard against a rare failure. Use history, telemetry, tests, and conversation to distinguish them. Cleaning code without recovering its context can revive incidents the organization has forgotten how to diagnose.
Practice
- Search commit and incident history before removal.
- Add a test that captures the observed behavior.
- Replace folklore with a clear comment or design record.
Anti-pattern
Deleting an ugly guard because no current teammate remembers why it exists.
