  "bluf": "This node addresses MITRE ATLAS technique AML.T0018.001 (Modify AI Model Architecture). Adversaries may directly modify an AI model's architecture to re-define it's behavior. This can include adding or removing layers as well as adding pre or post-processing operations. The effects could include removing the ability to predict certain classes, adding erroneous operations to increase computation costs, or degrading performance. Additionally, a separate adversary-defined network could be injected into the computation graph, which can change the behavior based on the inputs, effectively creating a backdoor. 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.T0018. ATLAS-mapped mitigations: AML.M0005 Control Access to AI Models and Data at Rest, AML.M0008 Validate AI Model, AML.M0013 Code Signing.",
