TARGET_DUPLICATE

What failed

Crux found more than one exported flow() or durableTask() with the same literal target name, or more than one Effect recovery definition for the same (id, version) on a RuntimeProgram.

Why

Runtime target names and Effect recovery identities are persisted routing keys. A wake or a cold recovery must resolve one identity to exactly one declaration.

What still works

Object-bound calls still work while you fix the duplicate. Runtime artifact generation, createRuntimeProgram(), and handler construction fail for the conflicting program.

Fix

For flows and durable tasks, rename one target and regenerate artifacts:

crux runtime generate

For Effect recovery targets, pass one definition object per (id, version). Identical objects collapse; different objects for the same pair throw:

createRuntimeProgram({
  targets: [reviewFlow],
  transports: [],
  // One recoverable definition per (id, version).
  effectTargets: [updateCustomer],
});

If two modules both export a recoverable Effect with the same id and version, export only one of them into effectTargets or change one version after updating its recovery contract.
