An interleaved row is routed to the most recently opened table · case 04

A structured table violates the declared record or column contract.

Member previewVariant 4 · 3 implementations · 8 checks per implementation

Case contract

Read pipe messages OPEN|id|header, ROW|id|comma-values, CLOSE|id|empty. Multiple table IDs may be open concurrently. IDs cannot reopen after close; rows require an active ID and matching width. Close emits [id, rows] in close order; EOF with open tables rejects.

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
interleaved	`[["b", [["cellcellcellcell"], ["z"]]], ["a", []]]`	`[["b", [["z"]]], ["a", [["cellcellcellcell"]]]]`	Failed
