## Description

Audit and migrate Table v8 to v9. Inventory affected APIs, follow the shared checklist, and read only the required architecture, state, feature, and TypeScript mappings.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Migrate Table v8 to v9

Read [core](../core/SKILL.md) first. Audit every item below before choosing detailed mappings. This shared checklist owns the complete core migration; the installed adapter's migration skill owns construction, rendering, framework requirements, and reactive wiring.

## Procedure

1. Establish passing tests for the existing table and inventory its enabled interactions, imports, options, and state owners.
2. Follow the whole audit checklist. Read a mapping reference when the audit finds affected code; preserve behavior while migrating features and construction.
3. Load the installed adapter with `intent load <package>#migrate-v8-to-v9` and its `table-state` skill. Substitute the actual adapter package. React, Preact, Solid, Svelte, Vue, Angular, and Lit have migration skills; Alpine, Ember, and Octane have no v8 adapter migration journey.
4. Type-check, exercise every enabled interaction and client/server stage, and complete the explicit v9 setup.

Treat `useLegacyTable` as a deprecated React-only bridge for an existing incremental migration. It bundles every feature, can exceed the v8 bundle, and is not the target architecture. Its only entrypoint is `@tanstack/react-table/legacy`.
