Transposed columns are emitted in reverse physical order · case 02

A structured table violates the declared record or column contract.

Member previewVariant 2 · 3 implementations · 8 checks per implementation

Case contract

Transpose comma records into physical columns. Pad missing trailing cells with null, preserving explicit empty strings. Width is the largest source row width; empty input has no columns. Output columns are in increasing physical position.

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.

Boundary fixture	Actual	Expected	Outcome
ragged	`[["b", null], ["a", null], ["cellcell", "x"]]`	`[["cellcell", "x"], ["a", null], ["b", null]]`	Failed
