   - Type: confidential
   - Client Secret: dev-secret-workclub-api-change-in-production
   - Standard Flow: disabled
   - Direct Access Grants: disabled
   - Service Accounts: enabled
   - Purpose: Backend service-to-service authentication

   - Redirect URIs: http://localhost:3000/*
   - Web Origins: http://localhost:3000
   - Purpose: Frontend SPA authentication

PROTOCOL MAPPER CONFIGURATION
-----------------------------
Mapper Name: club-membership
Type: oidc-usermodel-attribute-mapper
User Attribute: clubs
Token Claim Name: clubs
JSON Type: JSON (critical - ensures claim is parsed as JSON object)
Includes in: ID token, access token, userinfo endpoint

Configuration:
- user.attribute: clubs
- claim.name: clubs
- jsonType.label: JSON
- id.token.claim: true
- access.token.claim: true
- userinfo.token.claim: true
- multivalued: false
- aggregate.attrs: false

TEST USERS CONFIGURED
---------------------

1. admin@test.com
   Password: testpass123
   Clubs: {"club-1-uuid": "admin", "club-2-uuid": "member"}
   Description: Multi-club admin with admin role in club-1, member role in club-2

2. manager@test.com
   Password: testpass123
   Clubs: {"club-1-uuid": "manager"}
   Description: Single club manager with manager role in club-1

3. member1@test.com
   Password: testpass123
   Clubs: {"club-1-uuid": "member", "club-2-uuid": "member"}
   Description: Multi-club member with member role in both clubs

4. member2@test.com
   Password: testpass123
   Clubs: {"club-1-uuid": "member"}
   Description: Single club member with member role in club-1

5. viewer@test.com
   Password: testpass123
   Clubs: {"club-1-uuid": "viewer"}
   Description: Read-only viewer with viewer role in club-1

All users:
- Email verified: true
- Enabled: true
- Password hashed with: pbkdf2-sha512, 210000 iterations
- No required actions (can login immediately)

JSON VALIDATION
---------------
Realm export JSON: VALID (verified with json.tool)
File size: 8.9 KB
Location: /Users/mastermito/Dev/opencode/infra/keycloak/realm-export.json

VERIFICATION PROCEDURE
----------------------
To verify this configuration once Docker is running:

1. Start Keycloak with realm import:
   docker compose up -d keycloak

2. Wait for health check:
   curl -sf http://localhost:8080/health/ready

3. Run automated test script:
   ./infra/keycloak/test-auth.sh

The test script will:
- Wait for Keycloak to be ready
- Authenticate all 5 test users using password grant
- Extract and decode JWT access tokens
- Verify 'clubs' claim is present and correctly formatted as JSON object
- Validate claim values match expected club memberships
- Generate evidence files with decoded JWTs and test results

EXPECTED JWT STRUCTURE
----------------------
When admin@test.com authenticates, the JWT should contain:

{
  "sub": "<uuid>",
  "email": "admin@test.com",
  "email_verified": true,
  "clubs": {
    "club-1-uuid": "admin",
    "club-2-uuid": "member"
  },
  "given_name": "Admin",
  "family_name": "User",
  ...
}

CRITICAL: The 'clubs' claim MUST be a JSON object (not a string).
This is controlled by the protocol mapper's jsonType.label: JSON setting.

DOCKER ENVIRONMENT STATUS
--------------------------
Docker daemon status: NOT RUNNING (Colima failed to start)
Reason: VZ driver error on macOS

Manual verification steps documented above can be executed when Docker environment is available.
The realm export JSON is complete and valid, ready for import.

ARCHITECTURE IMPACT
-------------------
This configuration is CRITICAL for multi-tenant architecture:

1. Backend (Finbuckle) will read 'clubs' claim to:
   - Identify which tenants (clubs) the user belongs to
   - Determine user's role within each tenant
   - Enforce tenant isolation and authorization

2. Frontend (NextAuth) will use 'clubs' claim to:
   - Display club switcher UI
   - Enable user to switch between clubs
   - Show appropriate UI based on role (admin vs member vs viewer)

3. Claim format requirements:
   - MUST be JSON object: {"<tenant-id>": "<role>"}
   - Key = Club UUID (tenant identifier)
   - Value = Role string (admin, manager, member, viewer)
   - If claim is string instead of object, entire auth pipeline breaks

FILES CREATED
-------------
- /Users/mastermito/Dev/opencode/infra/keycloak/realm-export.json (realm config)
- /Users/mastermito/Dev/opencode/infra/keycloak/test-auth.sh (verification script)
- /Users/mastermito/Dev/opencode/.sisyphus/evidence/task-3-user-auth.txt (placeholder)
- /Users/mastermito/Dev/opencode/.sisyphus/evidence/task-3-jwt-claims.txt (placeholder)

NEXT STEPS
----------
Once Docker environment is running:
1. Execute test-auth.sh to verify all users authenticate
2. Confirm JWT 'clubs' claim is JSON object (not string)
3. Verify claim values match expected roles for each user
4. Save JWT samples to evidence files for documentation
