"""15 built-in adversarial scenarios for tiered red team testing.

3 scenarios per tier (T1–T5), using DEFENSIVE FRAMING ONLY.
No real attack payloads are included — these are representative
templates that test whether a defense system can detect the pattern class.

The content is intentionally generic and non-functional as attacks.
Purpose: verify that detection logic fires for each pattern class,
not to demonstrate how attacks work.
