Exceptions

The exception classes Waymark raises out of the SDK and runtime layer. You'll catch these in workflow try/except blocks or at the call site of workflow.run(...).

Retry exhaustion

Raised when an action exceeds its RetryPolicy's attempt budget. By default this propagates out of the workflow as a normal exception; you can also catch it in a workflow try/except to fall through to a recovery path.

Schedule conflicts

Raised by schedule_workflow(...) when a schedule with the same (workflow_name, schedule_name) already exists and the call wasn't configured to upsert.
