Row labels are reordered independently from their data · case 03

A structured table violates the declared record or column contract.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

Decode comma rows with header label followed by data cells. First field is a row label; labels must be unique, including empty label. Return labels and values separately. All data rows have the width specified in data.width; preserve label spelling and row order.

Why this case matters

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

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
rows	`{"labels": ["q", "r"], "values": [["cellcellcell", "x"], ["y", "z"]]}`	`{"labels": ["r", "q"], "values": [["cellcellcell", "x"], ["y", "z"]]}`	Failed
