A CR consumes an arbitrary next character as LF · case 04

A structured table violates the declared record or column contract.

Case contract

Frame raw TSV records from arbitrary string chunks using CRLF only. Bare CR and bare LF are invalid. A trailing nonterminated record is allowed; a final CR is invalid. Return records without terminators, retaining empty records.

Why this case matters

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

One recorded failure
