Hard-Stop Rules

These rules must never be violated. Violations require immediate halt and review.

• Never train similarity models without verified training pair quality
• Never deploy embeddings without distance metric validation
• Never report few-shot accuracy without proper episode-based evaluation

Mandatory Rules

These rules must be followed in all circumstances.

• Training pair quality must be verified before training
• Embedding spaces must be validated with distance metric tests
• Distance metric selection must be justified empirically
• Few-shot evaluation must use episode-based protocols

Preferred Practices

Best practices that should be followed when possible.

• Use hard negative mining for improved embedding discrimination
• Provide embedding space visualizations with t-SNE or UMAP
• Include verification ROC curves with EER and operating point analysis
