🏗️ Architecture Highlights

4-Layer Security (Winston's Design)

Layer 1: Database (FKs, constraints, unique indexes)
Layer 2: Model (scopes, validations, security methods)
Layer 3: Controller (authorization, security events)
Layer 4: UI (route guards, client validation)

Cryptographic Token System

• Generation: SecureRandom.urlsafe_base64(64) (512 bits)
• Storage: SHA-256 hash only
• Enforcement: Redis SETNX with TTL
• Single-use: Atomic operations prevent race conditions

Security Event Types (6 total)

1. unauthorized_institution_access
2. insufficient_privileges
3. token_validation_failure
4. rate_limit_exceeded
5. invitation_accepted
6. super_admin_demoted

🎯 Key Features Implemented

✅ Data Isolation

• Institution.for_user(user) scope used everywhere
• user.can_access_institution?(inst) verification
• Cross-institution access attempts logged and blocked

✅ Role-Based Access

• cohort_super_admin: Full management
• cohort_admin: Cohort management only
• Existing DocuSeal roles preserved

✅ Rate Limiting

• Max 5 pending invitations per email
• Per-institution enforcement
• Redis-backed counter

✅ Token Security

• 24-hour expiration
• Email verification required
• Single-use enforcement
• Never logged in plaintext

✅ Audit Trail

• All security events logged
• IP address capture
• Details in JSONB
• CSV export capability

✅ Integration Compatibility

• Zero impact on existing DocuSeal features
• Additive database changes only
• Existing authentication preserved
• CanCanCan extended, not replaced
