GENERATION_MODEL_NOT_STATIC

What failed

session() selected a bound model that is absent from RuntimeProgram.generationModels.

Why

Durable Session execution can only pin models that the immutable Runtime program declares. Dynamic, undeclared models would break reconnect and worker loading.

What still works

Declared models and Sessions that already use them remain available. No Session, Work, or Thread mutation occurs for the failed call.

Fix

Add the selected model to program construction or the generated program inputs:

createRuntimeProgram({
  targets: [support],
  generationModels: [supportModel, overrideModel],
  transports: [],
});

Then regenerate Runtime artifacts before deploying app and worker processes.
