Vyral Execution Azure Durable Local Host Skeleton

This folder is a local-only skeleton for Azure Functions host settings. It intentionally does not include deployed Azure resource names, account keys, or service-specific settings.

The production contract remains SDK-neutral in Vyral.Execution.AzureDurable. A concrete Functions app wraps Azure Functions bindings around:

AzureDurableExecutionRuntimeAdapter
AzureDurableExecutionClient
IAzureDurableExecutionOrchestrationScheduler
IAzureDurableExecutionOrchestrationDriver
AzureDurableExecutionHost

Plugin code should still depend only on Vyral.Execution.

Local Defaults

The clean local defaults are pinned by AzureDurableLocalHostSmokeOptions and mirrored here:

AzureWebJobsStorage=UseDevelopmentStorage=true
FUNCTIONS_WORKER_RUNTIME=dotnet-isolated
AzureFunctionsJobHost__extensions__durableTask__hubName=VyralExecutionLocal
VYRAL_EXECUTION_AZURE_LOCAL_HOST_SMOKE=0

Copy local.settings.sample.json to local.settings.json only for local development. Set VYRAL_EXECUTION_AZURE_LOCAL_HOST_SMOKE=1 when intentionally running a local smoke with Functions Core Tools and local development storage.

The smoke path should skip cleanly when func or local development storage is unavailable. It should not connect to deployed Azure resources by default.

Intended Host Shape

// HTTP or timer trigger:
// - create an ExecutionRunRequest
// - call AzureDurableExecutionRuntimeAdapter.StartRunAsync(...)

// Orchestrator function:
// - read AzureDurableStartCommand
// - call AzureDurableExecutionHost.OrchestrateAsync(...)
// - provide a replay-safe state driver over the Durable context

// Start activity:
// - call AzureDurableExecutionHost.StartRunWithReservationAsync(...)

// Step activity:
// - call AzureDurableExecutionHost.ExecuteOrchestrationStepAsync(...)

This skeleton is deliberately not a live cloud smoke. See samples/Vyral.Execution.AzureDurableFunctionsSmoke for the deployable isolated gate.
