# EM-LEG-01 provider comparison

Claude and Grok independently select **PROFILE** over WM-ECO-006 and WM-XCT-029 with no new catalogue or runtime identifier. Contract Amendment remains an agreement-owned instrument, Fulfilment Evidence remains duty-owned status plus externally mastered payload, and contractual SLA is an executed clause set plus enforceable duties.

Both providers assign immutable agreement identity, signed expressions, clause work IDs, amendments, termination and contract-record governance to WM-ECO-006. WM-XCT-029 owns live duty roles, conditions, fulfilment, outstanding quantity, evidence status, dispute, breach, cure and consequences. Contract state never duplicates duty state; duty records cite exact clause work and expression locators without restating normative text.

Both distinguish contractual SLA from internal SLO. WM-SFT-016 remains reference-only and may later own measurement and error-budget semantics, never contractual standing, remedies or breach. Grok strengthens execution-time occupancy, delegation/novation typing, evidence-revocation reopening and regime-qualified service-credit classification.

Canonical publication remains held by non-canonical bases, unratified overlap crosswalks, missing delegation types, unresolved acceptance/discharge semantics, the WM-SFT-016 stub and jurisdiction-specific legal rules.
