Atomic table row editing: editable schema · case 02

The table editable schema result violates the stipulated atomic table row editing contract.

Member previewVariant 2 · 3 implementations · 7 checks per implementation

Case contract

Row commits validate the merged draft atomically, reject unknown schema fields, ignore readonly fields, preserve untouched cells and stable identity, reject revision conflicts, suppress no-ops, and increment the revision only after actual changes.

Why this case matters

An offline table UI model isolates atomic table row editing, including adversarial row/column relationships.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
readonly draft	`{"fields": ["b"], "revision": 5, "row": {"a": 1, "b": 9, "id": "r"}, "status": "saved"}`	`{"fields": [], "row": {"a": 1, "b": 2, "id": "r"}, "status": "unchanged"}`	Failed
