--- MORBAC PostgreSQL Extension - Activity and View Hierarchies Tests
+-- Hierarchy Tests
--- ============================================================================
+-- =============================================================================
--- This test file covers activity and view hierarchy tests including:
+-- Tests all four hierarchy types:
--- - Activity hierarchy (e.g., write implies read)
+--   1. Role hierarchy — senior roles inherit permissions of junior roles (transitive)
--- - View hierarchy (e.g., sensitive_data is a type of documents)
+--   2. Activity hierarchy — requesting a senior activity also matches junior-activity rules
--- - Effective activities and views
+--   3. View hierarchy — requesting a senior view also matches junior-view rules
--- - Permission inheritance through hierarchies
+--   4. Org hierarchy — get_org_ancestors / get_org_descendants traversal
 --
--- Prerequisites: Assumes 00_setup.sql has been run to set up base data
+-- Hierarchy semantics in this system:
--- ============================================================================
+--   Activity: (senior='write', junior='read') means get_effective_activities('write')
+--             returns {write, read}, so a rule for 'read' ALSO covers 'write' requests.
+--   View:     (senior='financial_data', junior='documents') means
+--             get_effective_views('financial_data') returns {financial_data, documents},
+--             so a rule for 'documents' ALSO covers 'financial_data' requests.

--- This test file covers delegation functionality including:
+-- Tests the role delegation feature:
--- - Temporary role delegation
+--   - Active delegation grants the delegate the delegator's role permissions
--- - Delegated permission inheritance
+--   - Expired delegations are inactive
--- - Comprehensive role reporting (direct + delegated)
+--   - Future delegations are not yet active
--- - Time-limited delegation (valid_from/valid_until)
+--   - Revoked delegations are inactive
+--   - Delegator must hold the role (delegation from source is validated)
+--   - Negative role assignments override delegations
+--   - Delegated roles participate in role hierarchy
+--   - get_comprehensive_roles reports delegation source
 --
--- Prerequisites: Assumes 00_setup.sql has been run to set up base data
+-- Scenario:
--- ============================================================================
+--   Carol (manager) delegates her manager role to Leo (employee) for 1 day

--- ============================================================================
+-- =============================================================================
--- This test file covers temporal constraints including:
+-- Tests time-bounded rules using valid_from and valid_until on the rules table.
--- - Rules with valid_from timestamps (future activation)
--- - Rules with valid_until timestamps (expiration)
--- - Rules with both valid_from and valid_until (time windows)
--- - Authorization decisions respecting temporal bounds
 --
--- Prerequisites: Assumes 00_setup.sql has been run to set up base data
+-- Cases:
--- ============================================================================
+--   1. is_rule_valid() helper function tested directly
+--   2. is_active flag set by trigger on insert/update
+--   3. Expired rule (valid_until in the past) -> denied
+--   4. Future rule (valid_from in the future) -> denied
+--   5. Active time window (valid_from past, valid_until future) -> allowed
+--   6. Multiple rules for same combination — only active ones count
+--   7. Expired prohibition: no longer blocks access after it expires
+--   8. Temporal rules interact correctly with role hierarchy
+--
+-- Note: Direct rule inserts are used (bypassing Policy DSL) to control timestamps.
+-- Uses a dedicated view 'temp_view' for isolation so existing rules aren't disturbed.

--- ============================================================================

--- This test file covers cross-organizational authorization including:
+-- Tests inter-organizational access via the cross_org_rules table.
--- - Cross-organization rules (access between different orgs)
--- - Inter-organizational collaboration scenarios
--- - Cross-org permission validation
 --
--- Prerequisites: Assumes 00_setup.sql has been run to set up base data
+-- Scenarios:
--- ============================================================================
+--   1. No cross-org rule: users in org A cannot access org B resources
+--   2. Cross-org permission: specific role in source org can access target org
+--   3. User must hold role in source org (not just any role)
+--   4. Cross-org prohibition: blocks access even if there's a regular permission
+--   5. Cross-org rules combine with activity hierarchy
+--   6. Cross-org rules combine with view hierarchy
+--   7. Temporal cross-org rules (valid_from / valid_until)
+--
+-- Company context:
+--   Judy (sales_rep at Sales) is allowed to read GlobalTech reports via cross-org rule
+--   Nina (eng_auditor at Engineering) has a temporal cross-org rule to read GlobalTech audit_logs
+--   Diana (sales_manager at Sales) has a cross-org prohibition on writing Engineering docs

--- This test file covers audit logging functionality including:

--- - Enabling audit on tables
+-- audit_log entries for INSERT, UPDATE, and DELETE operations.
--- - Auditing INSERT operations
--- - Auditing UPDATE operations
--- - Auditing DELETE operations
--- - Audit log queries and reporting
--- - Disabling audit
 --
--- Prerequisites: Assumes 00_setup.sql has been run to set up base data
+-- Cases:
--- ============================================================================
+--   1. Enable audit creates trigger on specified table
+--   2. INSERT to audited table creates an audit log entry
+--   3. DELETE from audited table creates an audit log entry
+--   4. UPDATE to audited table creates an audit log entry with changed_fields
+--   5. All operations for a record_id are queryable
+--   6. Multiple tables can be audited independently
+--   7. Disable audit removes the trigger
+--   8. After disabling, changes are no longer logged

--- MORBAC PostgreSQL Extension - Administration Rules Tests
+-- Administration Rules Tests
--- ============================================================================
+-- =============================================================================
--- This test file covers administration rules including:
+-- Tests the admin meta-policy system: who can manage policies, roles, and users.
--- - Administrative activities (create_rule, etc.)
--- - Administrative permission checks (is_admin_allowed)
--- - Role-based administrative access control
--- - Administrative authorization decisions
 --
--- Prerequisites: Assumes 00_setup.sql has been run to set up base data
+-- is_admin_allowed(user_id, org_id, admin_activity, admin_target) is the main API.
--- ============================================================================
+-- Helper functions: can_manage_roles(), can_manage_policies(), can_manage_user_role().
+--
+-- Scenarios:
+--   1. Default deny: no admin rule = no admin access
+--   2. Grant admin permission to a role, verify the role holder can manage
+--   3. Admin prohibition blocks management even with permission
+--   4. Role hierarchy applies: senior role inherits admin permissions
+--   5. Admin helper functions
+--   6. can_manage_user_role() per-role management permission
+--   7. Admin rules are org-scoped
+--
+-- Company context:
+--   Grace (hr_manager) can manage users (assign_role) for employee-level roles
+--   Carol (manager) can create rules
+--   Alice (CEO) inherits Carol's admin perms via hierarchy
+--
+-- Prerequisites: 00_setup.sql -> 07_audit.sql
