FA-48435 / Delimited text / Member archive

An END marker emits a row with fewer fields than declared · case 05

A structured table violates the declared record or column contract.

Case contract

Process pipe records ROW|count, CELL|text, MORE|text, END|empty. CELL starts a new field; MORE concatenates to the most recent field without inserting characters. Each row declares a positive field count, completed at END. MORE without a field and excess fields reject. Multiple rows are allowed.

Why this case matters

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