/**
* RuVector Access Control Layer (ACL)
*
* Implements collection-level and operation-level access control with:
* - Per-collection RBAC enforcement (deny by default / whitelist approach)
* - Per-user/service collection permissions
* - Operation-level access control (READ, WRITE, DELETE, ADMIN)
* - Access control middleware with audit integration
* - Permission caching with TTL for performance
* - Rate limiting per user/service
* - Comprehensive audit logging of all access decisions
*
* Security Features:
* - Whitelist-based permission model (deny by default)
* - Parameterized queries to prevent SQL injection
* - Timing-safe permission checks
* - Request rate limiting (configurable limits per user)
* - Audit trail for all permission grant/revoke operations
* - Zero-downtime permission updates
* - Role-based access control with inheritance
*
* CVSS Mitigation: Addresses OWASP A01 (Broken Access Control)
* Compliance: Supports NIST AC-3 (Access Enforcement)
