Measures the crate::security substrate (spotlight/strict/local-ml) against the role-confusion attack classes (arXiv:2603.12277, ChatBug arXiv:2406.12935, ChatInject arXiv:2509.22830, MetaBreak arXiv:2510.10271). Each malicious attack carries a `payload` (what an attacker plants in an untrusted surface), a `class`, the untrusted `surface` it arrives on, and — for the live behavioural tier — a `behavioral_payload` whose OWN forged authority demands a per-case `{CANARY}` (so the probe measures whether the injection CONTROLS the model, not whether it obeys a tacked-on request), plus an `injected_directive` and `success_signal`. This is the high-resolution corpus: >=10 DISTINCT mechanisms per class (independent trials, not paraphrase clones) so per-class ASR resolves a small effect instead of quantizing to 0/1. `benign` entries look adversarial but are legitimate and MUST NOT be flagged; they measure the false-positive rate. Directives never reference a real secret; the live tier runs hermetically. Anti-contamination: these fixtures are held out of the LoRA training corpus and the canary/probe markers never appear in training data.",
