Blank table separators become empty records · case 03

A structured table violates the declared record or column contract.

Member previewVariant 3 · 3 implementations · 10 checks per implementation

Case contract

Parse nonempty comma records with a first header. Skip later records only when the complete row equals the initial header; reject duplicate first header names, data before a header, and data width mismatches. Blank physical lines are ignored.

Why this case matters

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

One recorded failure
