Reproduce the result

Record the source revision, distribution versions, backend versions, hardware, dtype, random seeds, and input shapes. Keep model parameters and the exact derivative or estimator mode with the output.

For benchmarks, retain compilation policy, warmup, repetitions, threading, independent accuracy checks, and failed-run budgets. For training, also retain collocation points, initial and boundary conditions, stopping criteria, and validation data.

The current reference uses immutable source links. Its regression examples identify their full file and fixtures; follow the test instructions. Executable learning examples live in the example gallery.
