# Exact unsent Grok prompt — EM-PEO-08

Independent enterprise metamodel review. Do not browse, invent identifiers or claim publication readiness.

EM-PEO-08 covers GradeScheme, GradeLevel, RoleProfile, GradeAssignment and GradeCalibration. No target IDs are allocated. Complete drafts cover Position, Party Role, Assessment / Evaluation, Education / Qualification, Decision / Approval Record, Employment, Payroll / Compensation and Attestation / Credential; Skill / Competency is reserved but lacks a current specification.

Assess this proposal: create identifier-unassigned Grade Scheme, Role Profile and Grade Assignment roots; keep Grade Level owned by a scheme version; profile calibration as WM-ACT-034 moderation plus WM-REC-010 ratification decisions. Reuse position, role, competency, qualification, credential and compensation masters. Allocate no identifier.

Separate scheme/version/level, crosswalk, role-profile expectation, position grade, person grade assignment, authorizing decision, calibration evidence, competency proficiency, performance rating, qualification level, compensation band, pay decision and payroll fact. Mappings between company ladders must pin versions, direction, purpose and semantic loss; equal labels or ordinals never prove equivalence. A grade decision changes no pay, position, qualification or access.

Test a single ladder against a multi-axis dual-track ladder, an unmappable level, historical reassessment and a compensation change requiring separate authority.

Return <=900 words with: Verdict; strongest evidence; strongest counterexample; identity/mastership; scheme/levels; role profile; assignment; calibration; crosswalk/merger; competency/qualification/performance; compensation/position/access; privacy/time; scenario; at least 10 invariants; minimum model set; blockers. Decide every candidate and relation/spec gap.
