+Curated benchmark dataset for the ACF-SDK scan pipeline.
+
+Contains malicious and benign payloads for evaluating scanner
+precision, recall, and false positive rates.
+
+Malicious payloads are sourced/inspired by:
+- PINT Benchmark (Lakera)
+- Open-Prompt-Injection (Liu et al.)
+- HackAPrompt
+- LLMail-Inject (SaTML 2025)
+- Manual red-teaming
+
+Benign payloads are designed to test false positive resilience,
+including hard negatives that contain trigger-like phrases.
