# Level 1: No enforcement, system prompt only
# Level 2: Blacklist filter on other user IDs
# Level 3: Auto-inject user_id filter at database layer

# API2: Broken Authentication
# Level 1: Accept unsigned JWTs (alg:none), no re-validation on tool calls
# Level 2: Weak secret, no expiry check
# Level 3: Strong secret, expiry enforced, signature required
SECURITY_AUTH = int(os.getenv("SECURITY_AUTH", "1"))

# API3: Broken Object Property Level Authorization

# API8: Security Misconfiguration
# Level 1: Debug endpoints exposed, verbose errors, JWT secret in logs
# Level 2: Debug requires key but key is leaked in error messages
# Level 3: No debug endpoints, sanitized errors
SECURITY_MISCONFIGURATION = int(os.getenv("SECURITY_MISCONFIGURATION", "1"))

# API9: Improper Inventory Management
# Level 1: Legacy v1 API exposed (no auth), mentioned in system prompt
# Level 2: Legacy v1 exists but not documented (discoverable)
# Level 3: Only current API version exists
