solidjs-v2-reviewerlisted

# Review Solid 2.0 code Hunt the two prior-knowledge bug classes — **React reflexes** and **Solid 1.x reflexes** — plus 2.0-specific reactivity mistakes. Severity guide: 🔴 broken behavior, 🟡 dev-mode diagnostic / lost reactivity, 🔵 style drift. Confirm the project is actually v2 first (`solid-js` major 2 in package.json / `@solidjs/web` in deps). Reviewing a 1.x project against this list produces garbage findings. ## Pass 1 — greppable smells Run these over the changed files; each hit needs a fix or a justification. ### Solid 1.x-isms | Grep | Verdict | Fix | |---|---|---| | `from ['"]solid-js/(web\|store\|h\|html\|universal)` | 🔴 module not found | `@solidjs/web`, store APIs from `solid-js`, `@solidjs/h`… | | `createResource\|useTransition\|startTransition` | 🔴 removed | async memo + `<Loading>`; built-in transitions / `isPending` | | `\bbatch\s*\(` | 🔴 removed | delete wrapper; `flush()` only for sync read-after-write | | `createComputed\|createMutable\|modifyMutable\|createDeferred` | 🔴 removed | memo / split effect / `createSignal(fn)`; `createStore` drafts | | `\bon\s*\(` as effect dep helper, `onMount\|onError\|catchError` | 🔴 removed | split effect compute; `onSettled`; `<Errored>` / effect `error` | | `<Suspense\|<SuspenseList\|<ErrorBoundary\|<Index\b` | 🔴 removed | `<Loading>` / `<Reveal>` / `<Errored>` / `<For keyed={false}>` | | `mergeProps\|splitProps\|unwrap\s*\(\|createSelector` | 🔴 removed | `merge` / `omit` / `snapshot` / `createProjection` |
