PR #1025's AC2 fixture (mkdir -p apps/*/venv/lib) does not do what it claims when the
glob is unmatched. rev-974 ran it exactly as written, caught the defect, re-ran the
intended assertion at an explicit path, and DISCLOSED the substitution rather than
silently reporting PASS.
Pre-registration protects a check from being retrofitted to the implementation. It
does not make the check correct. An unverified gate appeared inside the mechanism
built to catch unverified gates.
Requirement added to RM-02: the registry must self-verify that every registered case
actually runs and can actually fail — presence in the registry is not evidence.
