Saved table view restoration: unknown width column · case 05

The table unknown width column result violates the stipulated saved table view restoration contract.

Member previewVariant 5 · 3 implementations · 6 checks per implementation

Case contract

Restore a table view only at matching schema version; deduplicate known order, append new schema columns, keep required columns visible, accept positive-clamped integer nonboolean widths, validate pin sides/density/page-size enums, and ignore removed columns.

Why this case matters

An offline table UI model isolates saved table view restoration, including adversarial row/column relationships.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
schema evolution	`{"density": "comfortable", "hidden": ["b"], "order": ["b", "a", "c"], "page_size": 25, "pins": {"a": "right"}, "widths": {"a": 7, "b": 1, "gone": 8}}`	`{"density": "comfortable", "hidden": ["b"], "order": ["b", "a", "c"], "page_size": 25, "pins": {"a": "right"}, "widths": {"a": 7, "b": 1}}`	Failed
