FA-48035 / Delimited text / Member archive

Closing a grouped record leaves it open for later fields · case 05

A structured table violates the declared record or column contract.

Member previewVariant 5 · 3 implementations · 9 checks per implementation

Case contract

Read pipe rows: B|id opens an object, V|key|value adds a unique field, E|id closes and emits it. Nested begins, values outside an object, mismatched closes and EOF-open objects reject. Closed objects may reuse field keys. Preserve object order and text including empty values.

Why this case matters

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