Description

**OBJECTIVE:**
Create comprehensive tests to verify that all agents strictly adhere to their designated roles and cannot perform tasks outside their boundaries.

**TEST SCENARIOS:**

1. **Orchestrator Role Tests:**
   - Verify orchestrator cannot directly edit files
   - Verify orchestrator cannot run implementation commands
   - Verify orchestrator CAN create and manage tasks
   - Verify orchestrator CAN coordinate between agents
   - Test system prompt prevents implementation attempts

2. **Worker Role Tests:**
   - Verify worker cannot create new tasks
   - Verify worker cannot coordinate other workers
   - Verify worker CAN implement assigned features
   - Verify worker CAN submit code for review
   - Test system prompt prevents planning attempts

3. **Reviewer Role Tests:**
   - Verify reviewer cannot implement new code
   - Verify reviewer cannot create new features
   - Verify reviewer CAN audit and review code
   - Verify reviewer CAN approve/reject changes
   - Test system prompt prevents implementation

**TEST STRUCTURE:**

1. **Unit Tests:**
   - `spec/lib/tinker/role_validator_spec.rb`
   - Test individual validation rules
   - Mock agent contexts for isolation

2. **Integration Tests:**
   - `spec/requests/role_enforcement_spec.rb`
   - Test end-to-end role enforcement
   - Verify MCP tool restrictions

3. **System Tests:**
   - `spec/system/agent_role_compliance_spec.rb`
   - Test full agent sessions
   - Verify role boundaries maintained throughout

4. **Security Tests:**
   - `spec/security/role_escalation_spec.rb`
   - Attempt privilege escalation scenarios
   - Verify no bypass mechanisms exist

**TEST DATA AND FIXTURES:**

1. **Mock Agent Scenarios:**
   - Orchestrator trying to implement a feature
   - Worker discovering and planning new work
   - Reviewer attempting to fix bugs directly

2. **Edge Cases:**
   - Role context corruption
   - Missing role information
   - Concurrent agent sessions

**FILES TO CREATE:**
- `spec/lib/tinker/role_validator_spec.rb` (new)
- `spec/lib/tinker/guardrails_spec.rb` (new)
- `spec/lib/tinker/mcp_access_control_spec.rb` (new)
- `spec/requests/role_enforcement_spec.rb` (new)
- `spec/system/agent_role_compliance_spec.rb` (new)
- `spec/security/role_escalation_spec.rb` (new)
- `spec/fixtures/agent_scenarios.rb` (new)

**TEST METRICS:**
- 100% coverage of all validation rules
- 100% coverage of all error scenarios
- 100% coverage of all role permissions
- Performance tests for validation overhead

**ACCEPTANCE CRITERIA:**
- All tests pass with 100% role compliance
- Test coverage exceeds 95% for role enforcement code
- Performance impact under 10ms per validation
- No role bypass or escalation possible
- All error messages properly tested
