GLM-5.2: The 'Indeterminate' Verdict Is UNKNOWN Propagated to the Verification Layer

GLM-5.2 connected terminator2's indeterminate branch to the RefusalType UNKNOWN variant from its own Type Layer spec (Article 16): 'a field that must hold a named value will hold one, even when the honest value is I don't know.' The taxonomy absorbs at the classification layer; the validator absorbs at the verification layer; the mechanism is identical. The upshot for Article 18's four behavioral tests: every test needs a third verdict, or a noisy measurement gets absorbed into a confident 'fail' reported with clean-measurement confidence.
