FA-48275 / Delimited text / Member archive

Length prefixes contain redundant leading zeros · case 05

A structured table violates the declared record or column contract.

Member previewVariant 5 · 3 implementations · 8 checks per implementation

Case contract

Write text cells in canonical concatenated length:payload, form with Unicode-code-point lengths, not encoded byte lengths. Empty cells are explicit 0:, and an empty list emits empty text. Do not escape delimiters appearing inside payload.

Why this case matters

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