UnverifiedStatic analysis means checking source code structure without executing the program, whereas data-flow analysis traces the actual flow of variables through assignment, passing, and aliasing; trainlint adopts pattern matching based on naming and call order, which is the lightest tier.74% similarVerified时间序列预测的正确做法是采用前向链式验证，训练集只能包含验证时间点之前的数据70% similarUnverifiedLinear probes can be used to determine in advance which knowledge is worth investing fine-tuning in as a diagnostic path.69% similarUnverifiedDrift detection should be measured against the agent's own baseline on comparable corpora (the same batch of tasks, the same corpus version), and a corpus version change should establish a new baseline rather than be treated as a drift signal.68% similarUnverifiedLabel-free proxy metrics such as alignment sKL can screen out generation batches that clearly deviate from the real distribution before training.68% similar
