🎯 Changes

@tanstack/ai-persistence ships without a README.md, so its npm page is empty. This adds one in the same shape as the ai-memory README from #1417: banner, install, the server middleware (withPersistence), the client option (persistence: true vs. a storage adapter), reconstructChat for reloads mid-answer, the smallest custom adapter (defineAIPersistence + defineMessageStore), the seven stores by name, the @tanstack/ai-persistence/testkit conformance suite, and links to the persistence docs.

Every snippet is lifted from docs/persistence/{overview,build-your-own-adapter}.md — no new prose about behavior. Export names (withPersistence, reconstructChat, memoryPersistence, composePersistence, defineAIPersistence, defineMessageStore, the three client storage adapters in @tanstack/ai-client) checked against src/index.ts.

Patch changeset included so the README reaches npm ("docs in package" → patch).

Next in this series, if the shape still works: ai-anthropic, ai-fal, ai-utils, ai-event-client, ai-durable-stream, ai-skills, and the six ai-sandbox-* providers.

✅ Checklist

  • I have followed the steps in the Contributing guide.
  • I have tested code changes locally with pnpm run test:pr, or these tests do not apply to this pull request.
  • I fully understand the code in this pull request, including any code generated with AI assistance.
  • Docs: I updated docs/ for this change, or this change is not user-facing.
  • Changeset: I added a changeset (pnpm changeset), or this PR does not change a published package.

🚀 Release Impact

  • This change affects published code, and I have generated a changeset.
  • This change is docs/CI/dev-only (no release).

Summary by CodeRabbit

  • Documentation
    • Added comprehensive documentation for the AI persistence package, including installation and server/client integration.
    • Documented restoring conversations after a reload during an active response.
    • Added guidance for creating custom persistence adapters, using optional stores, composing backends, and validating adapters with the test suite.
    • Included authorization examples, adapter behavior requirements, licensing details, and links to related documentation.

The package had no README, so its npm page was empty. Same shape as the
ai-memory README (TanStack#1417); every snippet comes from docs/persistence.
