# SERENTECH SDK

The SERENTECH SDK is an internal SDK suite for official SERENTECH clients.

SDK source lives in the `serentech-sdk` repository. The SDK provides:

- TypeScript/JavaScript package for Node and browser overlays.
- Dart package for Flutter clients.
- Kotlin package for Android and JVM clients.
- Shared contract fixtures for Local Edge and MPFL cloud API shapes.

Local Edge is preferred for reads and writes. MPFL cloud provider APIs are
read-only for SDK clients and expose provisional live state from the Edge ->
MPFL direct-push cache. Certified stats come from the separate MPFL
certification lane, and the current push cache is not restart-safe or shared
multi-instance state.

See:

- `/docs/serentech` for the cloud API.
- `/docs/serentech/overlay.md` for overlay discovery behavior.
- `/llms.txt` for machine-readable entry points.
