FLX-5030: the fidelity block is malformed
Family: numerics (the 5000 band)
The block's shape does not match SEAM-FIDELITY-SPEC §2: a required section is missing, a section is not a mapping, a value has the wrong class, or a closed set (a property name, a tolerance type, a null policy, a failure action) was given a member it does not have. The block is refused before any statistic is formed.
