Action Complexity Authorization Security Tests (SECU-02.2).
Comprehensive tests for action complexity level enforcement:
- Level 1 (LOW): search, read, list, get, summarize, present_chart
- Level 2 (MODERATE): analyze, suggest, draft, generate, stream, submit
- Level 3 (HIGH): update, submit_form, send_email, create, post_message
- Level 4 (CRITICAL): delete, execute, deploy, payment
These are CRITICAL security tests ensuring complexity-based gating.
Failure indicates agents can perform high-risk actions without proper maturity.
