Fragment arrival order replaces physical field order · case 05

A structured table violates the declared record or column contract.

Member previewVariant 5 · 3 implementations · 7 checks per implementation

Case contract

Assemble one row from pipe fragments offset|comma-fields and a declared width. Offsets are zero-based unsigned ASCII integers. Fragments may arrive out of order, but overlap, overrun and holes reject. Empty fields are real supplied cells. Return the complete physical row.

Why this case matters

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

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
out of order	`["x", "z", "cellcellcellcellcell", "y"]`	`["cellcellcellcellcell", "y", "x", "z"]`	Failed
