A quoted cell loses its lexical origin · case 03

A structured table violates the declared record or column contract.

Member previewVariant 3 · 3 implementations · 16 checks per implementation

Case contract

Lex one physical comma record. A quote opens only at field start; doubled quotes decode inside quoted fields; after a closing quote only comma or EOF is legal. CR/LF outside quoted fields reject. Return fields and quote-origin flags; a physical newline inside quoted text remains literal.

Why this case matters

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