## Description

Migrate preact Table v8 to v9. Audit framework construction, rendering, state, and app hooks, with shared API changes in the core migration skill.

# Preact v8-to-v9 migration checklist

Before starting, run `intent load @tanstack/table-core#migrate-v8-to-v9`. Audit its entire shared checklist and read the detailed core mappings for APIs present in the application. This checklist adds the Preact-specific changes.

Framework prerequisite: Preact 10 or newer (`preact >=10`).

## Adapter audit

- [ ] Replace React-adapter imports and `useReactTable` with native `@tanstack/preact-table` and `useTable`.
- [ ] Remove compat aliases that existed only for Table. Preserve aliases still required by other libraries, including a React Virtual integration.
- [ ] Keep model inputs stable and configure explicit features/row-model slots; complete the shared core checklist.
- [ ] Use selected `table.state`, `table.Subscribe`, or Preact Store subscriptions; snapshots alone do not rerender consumers.
- [ ] Pair controlled slices with callbacks, or supply stable atoms from `@tanstack/preact-store`; remove global `onStateChange`.
- [ ] Use native Preact FlexRender components. Adopt `tableOptions` or `createTableHook` only for repeated app conventions.

## Load the affected details

When the audit finds old Preact construction, state, rendering, or app-hook code, read [adapter migration details](references/adapter-migration.md) before editing it. For a replacement render scaffold, read [getting started](../getting-started/SKILL.md). For controlled or stale state after migration, read [table state](../table-state/SKILL.md).

Shared pinning, sizing, sorting, selection, prototype-method, type, and registry changes stay in the core migration references. Renaming `useReactTable` alone does not complete the migration.

## Verify the migration
