Case contract

Cell drafts belong to a stable row-column pair and snapshot the original value and revision. Readonly cells cannot start/input/commit edits, cancellation discards the draft, commits validate required empty strings, reject stale revisions, and suppress unchanged writes.

Why this case matters

An offline table UI model isolates table cell draft lifecycle, including adversarial row/column relationships.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
wrong column	`{"draft": {}, "write": {"column": "x", "expected_revision": 3, "row": "r", "value": 2}}`	`{"draft": {"base": 1, "error": null, "key": ["r", "y"], "revision": 3, "value": 2}, "write": null}`	Failed
