Defined in:
lib/smith/errors.rb

Overview

Raised on restore when the persisted payload has the step_in_progress marker set AND the workflow class opted into ‘idempotency_mode :strict`. Signals that a previous worker crashed between `persist!` (before advance) and `persist!` (after advance); the step’s effects are unknown, so blindly re-running could double-execute non-idempotent agent calls or tools.
