Table cell render invalidation: field accessor change · case 02

The table field accessor change result violates the stipulated table cell render invalidation contract.

Member previewVariant 2 · 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.
