-- MORBAC PostgreSQL Extension - Constraint Tests
-- ============================================================================
-- This test file covers various constraints including:
-- - Separation of Duty (SoD) conflicts
-- - Negative role assignments
-- - Role cardinality constraints (min/max users per role)
-- =============================================================================
-- Constraint Tests
-- =============================================================================
-- Tests business constraints:
-- 1. Separation of Duty (SoD) — mutually exclusive roles
-- 2. Negative role assignments — explicit blocking of a role
-- 3. Role cardinality constraints min/max users per role
--
-- Prerequisites: Assumes 00_setup.sql has been run to set up base data
-- ============================================================================
-- Scenario:
-- - auditor and accountant are mutually exclusive (no one can hold both)
-- - Heidi (auditor) cannot be assigned accountant role
-- - Ivan (accountant) cannot be assigned auditor role
-- - Frank (contractor) is explicitly blocked from the employee role
-- - compliance_officer role has a min 1, max 2 cardinality constraint
--
-- Prerequisites: 00_setup.sql -> 03_delegation.sql
