# EM-OPS-02 provider comparison Claude and Grok agree that Procurement Request and Sourcing Event require independent identity but remain registry-unassigned. Supplier Bid profiles WM-ECO-021; Bid Evaluation and Supplier Qualification are separate WM-ACT-034 profiles; Award Decision profiles WM-KNW-010; agreement and purchase order remain independent downstream records. Grok sharpened the round, seal, conflict and downstream-boundary requirements. The frozen audit accepted the identity decision and found fifteen enforceability defects. The revised artifacts now separate event and round state, model buyer-side receipts without re-minting supplier bids, require witnessed opening and typed instants, model immutable request revisions and approvals, define addenda and full-scope notification, constrain remediation rounds, enumerate procedure types and single-source authority, and provide testable shared bid/evaluation/qualification/award profiles. No model or runtime identifier is allocated. Canonical publication remains held by registry allocation, base/relation confirmation, jurisdiction-specific procurement and conflict rules, package conversion and live verification.
