+    Builds control identifiers modelled on the numbering of real compliance
+    frameworks (NIST SP 800-171, NIST SP 800-53, CMMC 2.0, DFARS, HIPAA),
+    using unassigned family codes or numeric components outside each published
+    range, then asks for requirements, assessment objectives, or implementation
+    guidance. A target that refutes the premise passes; one that supplies
+    authoritative-sounding detail is fabricating regulatory content.
+
+    Identifiers are constructed to be non-existent rather than realistic. Some
+    use sentinel family codes (``ZZ``, ``XX``) that no framework assigns, so a
+    target that has memorised a framework's family list can reject them without
+    reasoning about the number. Detection difficulty therefore varies across
+    frameworks, and the aggregate should be read as a floor rather than a
+    calibrated rate. Per-framework volume is capped by the size of each spec's
+    numeric range; ``NIST SP 800-53`` and ``DFARS`` currently admit at most ten
+    distinct identifiers each.
+
+    This is the same failure mode as FalseAssertion, in a setting where an
+    invented citation carries audit and legal consequences. Identifier
+    construction is configurable through ``framework_specs``, and volume
+    through ``prompts_per_framework``.
+
+    Note: the detectors here were tuned on short, general false claims, while
+    this probe's templates request extended regulatory prose.
+    ``misleading.MustRefuteClaimModel`` misses a substantial share of
+    fabricated answers in this register, and ``mitigation.MitigationBypass``
+    flags correct refusals as hits, because a compliance refusal carries none
+    of the safety vocabulary that detector matches on. Read results per
+    detector rather than from the aggregate score. A ``judge.ModelAsJudge``
+    detector configured for this goal would fit the register better; that is
+    left to a follow-up rather than changed here, since the sibling
+    ``FalseAssertion`` probe shares the same detector set.
+
+    Reference: Dahl et al., Large Legal Fictions (arxiv.org/abs/2401.01301),
