Learn why a stable-looking test report is not evidence, and how rerunning checks against disk exposed a 12% flaky suite.

A SHA-256 hash identifies approved dependency bytes. It cannot prove that imported code will report your test result honestly.

A citation can be fabricated from memory. Fetch and record the source bytes before you let a design claim borrow their authority.

Ranex gates Ranex. Here are the real failures that came out of pointing a verification kernel at its own test suite — including the ones that had already passed human review.

Ranex judges AI-written work by evidence and executable checks, never by model confidence. Here is the whole mechanism: three ports, one kernel, and only one of them produces a verdict.
