}

Cost model configuration for semantic diff operations.

Costs are used to determine the minimum-cost alignment between two SBOMs. Higher costs indicate more significant changes.

Fields

component_added: u32

Cost for adding a new component

component_removed: u32

Cost for removing a component

version_patch: u32

Cost for patch version change

version_minor: u32

Cost for minor version change

version_major: u32

Cost for major version change

license_changed: u32

Cost for license change

supplier_changed: u32

Cost for supplier change

ml_model_changed: u32

Cost for ML model metadata change

dataset_changed: u32

Cost for dataset metadata change

ml_approach_changed: u32

Cost for ML approach change (e.g. supervised -> reinforcement-learning)

ml_architecture_changed: u32

Cost for ML architecture change (family or name, e.g. cnn -> transformer)

ml_task_changed: u32

Cost for ML task change (e.g. nlp -> computer-vision)

ml_quantization_changed: u32

Cost for ML quantization change (e.g. fp32 -> int4); a model-swap signal

ml_model_card_changed: u32

Cost for ML model-card URL change

ml_training_dataset_added: u32

Cost for adding a training dataset to a model

ml_training_dataset_removed: u32

Cost for removing a training dataset from a model (provenance loss; HIGH)

dataset_type_changed: u32

Cost for dataset type change (e.g. training -> validation)

dataset_governance_changed: u32

Cost for dataset governance owners change

dataset_sensitivity_added: u32

Cost for adding a dataset sensitivity classification (e.g. gaining PII; HIGH)

dataset_sensitivity_removed: u32

Cost for removing a dataset sensitivity classification

vulnerability_introduced: u32

Cost for introducing a vulnerability

vulnerability_resolved: i32

Reward (negative cost) for resolving a vulnerability

dependency_added: u32

Cost for adding a dependency

dependency_removed: u32

hash_mismatch: u32

Cost for hash mismatch (integrity concern)

crypto_algorithm_changed: u32

Cost for crypto algorithm family change

crypto_downgrade: u32

Cost for crypto security downgrade (weaker algorithm or lower security level)

crypto_key_rotated: u32

Cost for crypto key rotation

crypto_cert_expiry_changed: u32

Cost for certificate expiry date change

crypto_protocol_changed: u32

Cost for protocol version change

crypto_quantum_level_changed: u32
