The SDK defines backend-neutral contracts used by every adapter:

import {
  AdapterError,
  type CompileContext,
  type CompiledQuery,
  type DatasourceAdapter,
  type DatasourceCapabilities,
  type DatasourceManifest,
  type DiscoveryContext,
  type ExecutionContext,
  type QueryExplanation,
} from "@openplait/adapter-sdk";

Stable error codes distinguish invalid configuration, invalid parameters, unsupported operations, rejected native queries, execution failure, timeout, and cancellation. Applications should branch on codes rather than parse error messages.
