FLX-5041: value is outside the domain the kernel can hash
Family: numerics (the 5000 band)
A schema-declared JSON number could not be converted to the exact Decimal the kernel hashes (KERNEL-SPEC §2.1 keeps float out of every hashed value), or a probability landed outside [0, 1]. The offending value's class and path are named; the value itself is not, so a diagnostic never leaks a population value.
