Workflow Runtime
Navigate definitions, supervisors, durable state, recovery, and lifecycle behavior for Workflows.
The runtime subsection explains how a registered workflow becomes a durable, session-owned execution. Start with the Workflows overview, then choose the page that matches the seam you are implementing.
Runtime boundary
The definition page covers the typed contract and catalog lookup. The supervisor page covers activation, leases, workers, start acknowledgement, and shutdown. The state and history page explains which durable record owns each fact. The interruption and resume page covers checkpoint adoption and validated continuation input. The lifecycle page covers statuses, cancellation, and failure.
