defense-in-depth
About
Defense-in-depth is a validation skill for preventing bugs caused by invalid data by implementing checks at every system layer data passes through. It ensures bugs become structurally impossible by validating at entry points, business logic, environment guards, and with debug logging. Use this when failures occur deep in execution and single-point validation is insufficient.
