# EM-KNW-01 provider comparison

Claude and Grok independently select **PROFILE** over WM-REC-001, WM-KNW-006 and WM-KNW-018 with no new catalogue or runtime identifier. Knowledge Article is a documentary-form designation, Document Revision is record-owned and Term Definition is concept-owned. Independently identified assertions and decisions remain outside this contour and route to EM-KNW-02.

Both providers apply one ownership rule: an assertion that survives removal of every scheme is concept-owned; an assertion that loses meaning without an exact scheme release is scheme-owned. WM-KNW-006 therefore masters concept identity, intension, intrinsic definitions, designation inventory and global lifecycle. WM-KNW-018 masters immutable releases and release-scoped membership, hierarchy, mappings, notes and designation preference. Cross-model concept views are derived and read-only.

Both keep record identity separate from URL, path, file, carrier and digest. A move changes only location or instantiation; a declared significant-property change creates a fixing event and new version. WM-XCT-020 classification must pin subject, concept IRI, scheme IRI and exact release. Lexical equality and byte equality establish no semantic identity.

Grok sharpened the distinction between intrinsic definition and scheme-local scope note, made preferred designation release-scoped, and confirmed that scheme-local withdrawal differs from global concept retirement. It also requires definition-level source, language, context, access and dispute state.

Canonical publication remains held by non-canonical bases, overlapping WM-KNW-006/018 authority, optional scheme-binding cardinality, unresolved WM-KNW-002/018 and WM-XCT-020 parentage, and unratified definition access and dispute semantics. Standards remain alignment evidence until exact editions and usable crosswalks are pinned.
