Checks performed
  - sample-history chunks exist and are sequentially numbered
  - every chunk contains required metadata, sample, and loss arrays
  - metadata arrays match exactly across chunks
  - schema version matches the current observation-axis format
  - sample IDs are unique and cover 0..sample_count-1
  - parameter and loss arrays have the expected shapes and finite values
  - observation metadata covers every case/field/window exactly once
  - at least 2 sample(s) are present
  - at least one tuned parameter varies across samples
  checks: OK
