- Add __post_init__ to Batch that asserts len(metadata.time) equals the batch size and len(metadata.atmos_levels) equals the pressure-level dimension, raising ValueError on mismatch. - Use shape[-3] for the atmos level check so validation works for both input (b, t, c, h, w) and decoder output (b, c, h, w) batches. - Align test_aurora_small with the metadata.time contract for batch size two. Add unhappy-path tests in tests/test_batch.py.
