system. +// +// This package implements comprehensive role-based access control (RBAC) for contextual +// intelligence, ensuring that context information is appropriately filtered, encrypted, +// and distributed based on role permissions and security requirements. It integrates +// with the existing BZZZ crypto system to provide secure, scalable access control. +// +// Key Features: +// - Hierarchical role definition and management +// - Context filtering based on role permissions and access levels +// - Integration with BZZZ crypto system for role-based encryption +// - Dynamic permission evaluation and caching for performance +// - Role-specific context views and perspectives +// - Audit logging for access control decisions +// - Permission inheritance and delegation +// - Temporal access control with time-based permissions +// +// Core Components: +// - RoleManager: Definition and management of roles and permissions +// - AccessController: Access control decision making and enforcement +// - ContextFilter: Role-based filtering of context information +// - PermissionEvaluator: Dynamic evaluation of permissions +// - AuditLogger: Logging of access control events +// - EncryptionManager: Role-based encryption and key management +// +// Integration Points: +// - pkg/crypto: Role-based encryption and key management +// - pkg/slurp/context: Context filtering and access control +// - pkg/slurp/storage: Encrypted storage with role-based access +// - pkg/election: Leader-based role administration +// - pkg/config: Role configuration and policies +// +// Example Usage: +// +// roleManager := roles.NewRoleManager(storage, crypto) +// ctx := context.Background() +// +// // Define a new role +// role := &Role{ +// Name: "Senior Developer", +// Permissions: []Permission{ +// PermissionReadCode, +// PermissionWriteCode, +// PermissionViewArchitecture, +// }, +// AccessLevel: AccessLevelHigh, +// } +// err := roleManager.CreateRole(ctx, role) +// +// // Assign role to user +// err = roleManager.AssignRole(ctx, "user123", "senior-developer") +// +// // Filter context based on role +// filter := roles.NewContextFilter(roleManager) +// filteredContext, err := filter.FilterContext(ctx, originalContext, "senior-developer") +// +// // Check permissions +// controller := roles.NewAccessController(roleManager) +// canAccess, err := controller.CheckPermission(ctx, "user123", PermissionViewArchitecture) +// if canAccess { +// // Allow access to architectural context +// } +// +// Role Hierarchy: +// The system supports hierarchical roles where higher-level roles inherit +// permissions from lower-level roles. This enables flexible permission +// management while maintaining security boundaries appropriate for different +// team responsibilities and access needs. +// +// Access Levels: +// Context information is classified into different access levels (Public, +// Low, Medium, High, Critical) and roles are granted appropriate access +// levels. This ensures sensitive information is only available to +// authorized personnel while enabling collaboration on appropriate content. +// +// Temporal Access Control: +// The system supports time-based access control where permissions can be +// granted for specific time periods, enabling temporary access for +// contractors, time-limited elevated permissions, and automatic access +// revocation for compliance and security requirements. +// +// Performance Considerations: +// - Permission caching with configurable TTL for fast access decisions +// - Batch permission evaluation for efficiency with large contexts +// - Pre-computed role hierarchies and permission inheritance +// - Optimized context filtering algorithms for minimal overhead +// - Background permission synchronization across cluster nodes +// +// Security Model: +// All access control decisions are based on cryptographically verified +// role assignments and permissions. The system integrates with the BZZZ +// crypto infrastructure to ensure secure key distribution and context +// encryption, preventing unauthorized access even in case of node +// compromise or network interception. +// +// Audit and Compliance: +// Comprehensive audit logging tracks all access control decisions, +// permission changes, and context access patterns. This supports +// compliance requirements, security analysis, and debugging of +// access control issues while maintaining performance through +// asynchronous logging and efficient storage. +package

This supports +// architectural archaeology and decision rationale understanding. +// +// Performance Characteristics: +// - O(log N) lookup for temporal nodes by decision hop +// - O(N) traversal for decision paths within hop limits +// - Cached decision influence graphs for fast relationship queries +// - Background analysis for pattern detection and staleness scoring +// - Incremental updates to minimize computational overhead +// +// Consistency Model: +// Temporal data maintains consistency through eventual convergence across +// the cluster, with conflict resolution based on decision metadata and +// vector clocks. The system handles concurrent decision recording and +// provides mechanisms for resolving temporal conflicts when they occur. +package temporal \ No newline at end of file diff --git
