W014

Identity-breaking .map(p => ({ ...p, … })) feeding a keyed list: every row re-runs on every change (in-file, and across files via props in weft check).

Fix: Replace only the changed item (p.id === id ? { ...p, price } : p), or read the changing field live.

Status in weft@0.1.0: reported.

Triggers it:

import { state } from '@weft-js/core'export function A() { const xs = state([{ id: 'a', price: 1 }]); const push = (price: number) => { xs.value = xs.value.map(p => ({ ...p, price })) }; return <ul onClick={() => push(2)}>{xs.value.map(p => <li key={p.id}>{p.price}</li>)}</ul> }
