# Verified integration examples

These pages bind critical integration guidance to actual compiled SDK source. Run the commands from the SDK root with JDK 21; migration tests also require Docker.

- [Credential verification and tamper rejection](verification.md)
- [Pinned merchant authentication](merchant-authentication.md)
- [Wallet configuration rejection](wallet-configuration.md)
- [Persistent ledger migration](ledger-migration.md)

Also see the [host configuration and metrics example](../host/example.md) and [isolated fixture example](../../contributing/testing-guidelines.md). Other Markdown blocks remain inventoried fragments until explicitly converted and executed. A source match alone does not establish a successful test run.
