# Reference

This section collects stable contracts—APIs, schemas, database internals, and package integration guides.

## Database

* **[Schema Overview](/reference/database/schema-overview)** – Core tables, relationships, and conventions across the Tuturuuu platform database.
* **[Row-Level Security Policies](/reference/database/rls-policies)** – The security model and RLS patterns that gate workspace data access.
* **[Migrations Guide](/reference/database/migrations-guide)** – Creating, testing, and deploying Supabase migrations safely.

## Packages

* **[`tuturuuu` SDK](/reference/packages/sdk)** – Official TypeScript/JavaScript SDK for the platform.
* **[`@tuturuuu/masonry`](/reference/packages/masonry)** – High-performance, responsive masonry grid component for React.
* **[`@tuturuuu/utils/effect`](/reference/packages/utils-effect)** – Curated Effect entrypoint and Tuturuuu error helpers for typed server orchestration.
* **[`@tuturuuu/supabase`](/reference/packages/supabase)** – Supabase client creation patterns and utilities.
* **[`@tuturuuu/trigger`](/reference/packages/trigger)** – Trigger.dev task helpers and background-job patterns.

## API Reference

<Note>
  The platform is mid-migration from `apps/web` (Next.js, port 7803) toward `apps/tanstack-web` (TanStack Start) plus `apps/backend` (Rust). Some package and database reference pages—especially [`@tuturuuu/supabase`](/reference/packages/supabase) and [`@tuturuuu/trigger`](/reference/packages/trigger)—document `apps/web` patterns. The backend/TanStack equivalents are tracked in the [TanStack + Rust migration guide](/platform/architecture/tanstack-rust-migration).
