Automation and release boundary

The computation is deterministic: it parses quoted CSV fields, normalizes line endings and surrounding whitespace, removes blank rows and exact normalized duplicates, pads short trailing rows, and stops on unexplained extra fields. It does not infer missing values, resolve identities, or silently make semantic corrections. A release reviewer must approve the staged artifacts before delivery.
