# EM-LND-18 provider comparison

Claude and Grok agree on the frozen boundary: EnterpriseLandscape is an identifier-unassigned governed declaration with an independent revision lifecycle; Enterprise View Scope profiles immutable WM-KNW-012 expression/release identity; outputs are read-only, immutable and non-reimportable; every fact remains in its domain master; WM-XCT-039 is not a universal host; no identifier or runtime is allocated.

Grok sharpens four requirements. A scope release must explicitly carry perimeter, withheld marks, semantic-axis readings and the non-reimportable flag. Completeness is relative to the named question and perimeter, so a not-selected domain is never missing. Membership grants no access and withheld content cannot leak beyond an allowed existence marker. Three clocks remain separate: domain valid time, declaration revision time and release time.

The three-person firm and holding-group examples prove selective composition without installing all registry domains or copying data. Shared labels such as matter or revenue retain axis-local meanings. WM-XCT-039 may appear only as an optional projection target for an explicitly managed-IT question. The non-IT host remains an unresolved gap.

The single frozen Claude audit provider call accepted the prompt but timed out after nearly ten hours and returned zero bytes. It is recorded as spent and will not be rerun. Therefore the provider reconciliation is reviewable, while canonical publication remains held.
