When 'n/a' hides a bug: testing blind spots in hardware health checks

The test suite also passed, as it validated the same flawed logic. The bug was a portability miss: the tool never ran its temperature loop on Ryzen hardware.

The story is a sharp reminder that tests can pass because they share the same blind spots as the code they test, not because the system works.
