# Provider comparison — EM-LEG-02

Claude and Grok agree on the no-new-ID disposition: WM-POL-001 remains sole master of legal work, expression, manifestation, source, provision and norm identity; ExternalRequirement is a norm-layer profile and NormVersion is an expression-layer profile. WM-ACT-034 owns ApplicabilityAssessment identity and lifecycle. Jurisdiction is an external, time-qualified reference. WM-KNW-012 may supply attributable interpretation evidence, and WM-XCT-029 alone owns instantiated duties.

Grok strengthens the local synthesis in four places. Commencement must be provision-scoped rather than stored once on NormVersion. The six legal time axes, assessment facts-as-of and assessment performed-at must remain pairwise distinct. Issued assessment pins are immutable, concurrent peers coexist, and only explicit named supersession can replace an assessment. Citation, applicability, obligation and compliance are four separate claims; applicability must not instantiate a duty and compliance must not be stored on the assessment.

The reconciled result allocates no model or runtime ID and removes Jurisdiction from the allocation queue. Publication remains held until the base profiles can represent the temporal axes, provision-level commencement, structured assessment pins and external jurisdiction key-as-of contract.
