CONTRACTS: Implement Access Control Integration

[truthixify]

Description

Integrate the access control system with membership tokens and subscription contracts to provide unified permission management across the entire platform.

Files to Modify

• contracts/manage_hub/src/lib.rs - Add access control checks to all public functions
• contracts/manage_hub/src/membership_token.rs - Integrate with access control for token operations
• contracts/manage_hub/src/subscription.rs - Add role-based subscription access
• contracts/access_control/src/access_control.rs - Add cross-contract integration functions
• contracts/common_types/src/types.rs - Add unified permission structures
• contracts/manage_hub/src/attendance_log.rs - Add role-based attendance logging

Key Changes Required

1. Cross-Contract Integration - Modify all manage_hub contracts to call access control functions before operations
2. Role-Based Permissions - Implement different permission levels for different operations (admin, member, guest)
3. Token-Based Access - Integrate membership token validation with role assignments
4. Unified Permission Checks - Create common permission validation functions used across all contracts
5. Permission Caching - Implement efficient permission checking to avoid repeated cross-contract calls
6. Integration Testing - Add comprehensive tests for all cross-contract permission scenarios

Acceptance Criteria

• Connect access control with membership token validation
• Implement role-based subscription access (different tiers for different roles)
• Add cross-contract permission checks to all sensitive operations
• Create unified permission validation functions
• Update all contracts to use integrated access control
• Add comprehensive integration tests
• Implement permission caching for gas optimization
• Add permission audit logging

Hello Maintainers,

I would like to work on Issue #423: Implement Access Control Integration.

I have experience integrating access control systems across smart contracts and building unified permission layers.

For this task, I plan to:

• Integrate membership token validation and subscription contracts with the access control module.
• Implement role-based permissions for different operations (admin, member, guest).
• Create cross-contract permission checks and unified validation functions to ensure secure operations.
• Optimize with permission caching for gas efficiency and add audit logging.
• Write comprehensive integration tests to cover all scenarios and edge cases.

Hi! I’d like to contribute to this issue by integrating access control across membership tokens, subscriptions, and manage_hub contracts. I’m ready to implement cross-contract permission checks, unify roles and permissions, enforce role-based access for sensitive operations, integrate token-based access, add permission caching and audit logging, and include integration tests to ensure secure and correct behavior.

I’d like to take on this access control integration. I’ll wire unified permission checks across manage_hub, membership_token, subscription, and attendance_log, adding cross-contract helpers in access_control plus shared permission types/utilities in common_types to enforce admin/member/guest tiers consistently. I’ll also implement permission caching for gas efficiency, add audit logging for sensitive actions, and deliver comprehensive integration tests covering all cross-contract permission scenarios and failure modes.
