Map-cell parsing reverses entry keys and values · case 04

A structured table violates the declared record or column contract.

Member previewVariant 4 · 3 implementations · 8 checks per implementation

Case contract

Decode a semicolon-delimited row of map cells enclosed in braces. Inside a map, comma separates entries and first equals separates key and value. Empty braces represent an empty map; empty values are legal, empty or duplicate keys reject. Ordinary scalar cells remain text, even with equals.

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.
