Conversation workflow step that enqueues an event as part of the workflow. - Gas accounting (when and what is charged): - Base step charge (once per run of this step): 30. - Expression/template resolution under "/event" (if present): - Expressions run in the deterministic QuickJS VM (same sandbox and bindings as the JavaScript Code step). - VM gas is converted to host gas as: hostGas = ceil(wasmFuel / 1700) (calibration factor currently 1700 fuel per host gas unit). - Any document(<pointer>) used inside expressions/templates charges per call: 8 + depth(pointer) + ceil(snapshotBytes/100). - Event emission (enqueue): 20 + ceil(eventBytes/100) for the final event payload after expression resolution.
