FA-47994 / Delimited text / Member archive

A row is bound using the newest schema instead of its declared revision · case 04

A structured table violates the declared record or column contract.

Case contract

Read tagged pipe rows. S|version|headers installs a schema; D|version|values binds a data row to the matching installed version. Revisions are immutable, may be referenced out of installation order, and headers must be unique. Reject unknown version, duplicate revision, or incorrect row width. Return version plus named rows.

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.
