Consuming a row decreases a counted block by two · case 03

A structured table violates the declared record or column contract.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

Decode pipe records arranged as C|count followed by exactly count R|value rows. Multiple blocks may follow. Counts are ASCII nonnegative decimals; values contain no pipe in this bounded grammar. Empty blocks are emitted as empty lists. Missing, unexpected, and surplus R records reject.

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.
