Crate fakecloud_appsync 

AWS AppSync (appsync) restJson1 control plane + schema state for fakecloud.

The full 74-operation AWS AppSync Smithy model. AppSync signs SigV4 with the appsync scope and speaks restJson1; every operation is a RESTful <METHOD> /v1|/v2/... route with path labels (e.g. POST /v1/apis, GET /v1/apis/{apiId}, POST /v1/apis/{apiId}/types/{typeName}/resolvers), so requests are routed by their HTTP method + @http URI template.

This is real, persisted, account-partitioned control-plane + schema state, not a set of stubs:

• GraphQL APIs. CreateGraphqlApi mints an apiId, ARN, GRAPHQL + REALTIME endpoint uris, and echoes the auth config (API_KEY, AWS_IAM, AMAZON_COGNITO_USER_POOLS, OPENID_CONNECT, AWS_LAMBDA), round-tripping via Get/List/Update/Delete.
• Sub-resources. API keys (with expiry), data sources (all DataSourceTypes with their config echoed), resolvers (UNIT/PIPELINE, VTL or APPSYNC_JS code, attached to type.field), functions, schema types, API caches, domain names + API associations, the newer Event-API surface (CreateApi/channel namespaces), and merged/source-API associations. Every sub-resource op validates its parent and returns the declared NotFoundException when the parent (or the resource) is absent.
• Schema lifecycle. StartSchemaCreation ingests an SDL schema blob and settles GetSchemaCreationStatus to SUCCESS on read (a state machine like other async ops). GetIntrospectionSchema returns a representation (SDL or JSON per the format query param) derived from the stored schema.
• Evaluation. EvaluateCode / EvaluateMappingTemplate validate the code/template + context are well-formed and return a deterministic, honestly-documented evaluated result (see evaluate); they do NOT run a full VTL/APPSYNC_JS interpreter.

Model-driven validation rejects contract violations with the error codes each operation declares (BadRequestException universally, plus NotFoundException, ConcurrentModificationException, etc.).

Not yet implemented (documented gap, not stubbed): the GraphQL query execution data plane – actually resolving GraphQL queries/subscriptions against the configured data sources – is a later batch. This crate is the faithful control plane + schema state that such execution would build on.
