  "bluf": "This node addresses MITRE ATLAS technique AML.T0069.000 (Special Character Sets). Adversaries may discover delimiters and special characters sets used by the large language model. For example, delimiters used in retrieval augmented generation applications to differentiate between context and user prompts. These can later be exploited to confuse or manipulate the large language model into misbehaving. Defending against this technique is required under EU AI Act, NIST AI RMF, and ISO/IEC 42001 obligations; this node operationalises the documented ATLAS mitigations and cross-instrument controls into a deterministic verification workflow. Sub-technique of ATLAS AML.T0069.",
