# Solid hydration gate

`@stainless-code/persist/frameworks/solid` returns an `Accessor<boolean>` — call `hydrated()` inside tracking scopes (`createEffect`, JSX, …).

## Install

```bash
bun add @stainless-code/persist solid-js
```

Peer: `solid-js` `>=1.6.0`.

## Minimal wiring

```tsx
import { useHydrated } from "@stainless-code/persist/frameworks/solid";

const hydrated = useHydrated(prefsHydration);
// <Show when={hydrated()} fallback={<Skeleton />}>…</Show>
```

## Contracts

Null/undefined signal → hydrated `true`. SSR policy: treat as hydrated `true`.

## Common mistakes

- **Using `hydrated` as a boolean** — it's an accessor; call it.
- **Reading outside a reactive scope** — won't update.
- **Null signal ≠ loading** → hydrated true.

## API surface

- `useHydrated(signal) → Accessor<boolean>`
