Table cell render invalidation: new row mounts · case 05

The table new row mounts result violates the stipulated table cell render invalidation contract.

Member previewVariant 5 · 3 implementations · 8 checks per implementation

Case contract

Table invalidation uses column field accessors and stable row IDs; repaint follows value, symmetric selection, error-text, width, stripe parity, or theme changes. Only wrapped cells remeasure on value/width changes, and added/removed row IDs drive mount/disposal.

Why this case matters

An offline table UI model isolates table cell render invalidation, including adversarial row/column relationships.

Sample boundary fixture

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