A row window counts comment and blank physical records · case 05

A structured table violates the declared record or column contract.

Case contract

Select a half-open zero-based logical row window [start,stop) from physical comma lines. Column-zero # lines and completely empty physical lines are ignored before numbering; whitespace-only lines remain data. Return [one-based physical line number, split cells] for selected logical rows.

Why this case matters

Delimited interchange needs explicit framing, schema and field semantics at ingestion and emission boundaries.

One recorded failure
