A partial last column is dropped without an error · case 05

A structured table violates the declared record or column contract.

Case contract

Decode W|width followed by pipe-separated column-major cells in the second line. Width is a positive ASCII decimal; field count must be divisible by width. The second line empty denotes one empty cell. Return row-major rows, each exactly width cells. This bounded block requires exactly two physical lines.

Why this case matters

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

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
