FA-48568 / Delimited text / Member archive

A parsed unit retains its closing bracket · case 03

A structured table violates the declared record or column contract.

Member previewVariant 3 · 3 implementations · 11 checks per implementation

Case contract

Parse comma header cells with optional terminal [unit]. Return [name,unit-or-null]. Only one terminal bracket pair is allowed; name and unit must be nonempty. Bare header names are preserved including spaces; bracket text is not normalized. Duplicate full name/unit pairs reject, but one name with different units is allowed.

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.

units	`[["cellcellcell ", "kg]"], ["time", "s]"]]`	`[["cellcellcell ", "kg"], ["time", "s"]]`	Failed
