# Exact unsent Grok prompt — EM-DAT-04

Independent enterprise metamodel review. Do not browse, invent identifiers or claim standards conformance.

EM-DAT-04 covers DataQualityRule, QualityEvaluation, QualityIssue and CoverageAssessment. Reserved WM-DAT-007 is the quality-assessment aggregate; adjacent authorities are WM-KNW-013 rule, an unassigned Metric Definition candidate, WM-MAT-008 observation, WM-KNW-014 issue and WM-ACT-034 generic assessment.

Assess this proposal: WM-DAT-007 owns the purpose-qualified evaluation and verdict; rules, metric definitions, observations and issues remain external masters; CoverageAssessment is an assessment kind requiring a versioned frame and explicit denominator state. Completeness, accuracy, validity, freshness and coverage are separate. Denominator states are exact, estimated or unknown; unknown blocks ratios. Accuracy requires independent reference truth. Freshness names two clocks and a purpose budget. Corrections and remediation retests create successor assessments.

Test a fully populated but stale dataset and a 4% sample with strong measured accuracy. Return <=900 words with: Verdict; strongest evidence; strongest counterexample; identity/mastership; dimension definitions; denominator and uncertainty rules; lifecycle; scenario; at least 10 invariants; minimum completion shape; blockers. Explicitly decide whether CoverageAssessment needs its own identity and whether WM-DAT-007 may own metric formulas.
