# schemas/lib/workflow.ncl — Workflow contracts
|
|
#
|
|
# A Workflow composes operations across components, modes, and layers.
|
|
# Each step targets one or more component operations (install, update, backup, ...).
|
|
# Workflows connect to: FSM dimensions, NATS events, backlog items, action log.
|
|
#
|
|
# Relationship to DAG:
|
|
# dag.ncl — L2 server provisioning (SSH, always install, server-bound)
|
|
# workflows/ — L3 service lifecycle (cross-component, any operation, cross-mode)
|
|
#
|
|
# Usage:
|
|
# let w = import "schemas/lib/workflow.ncl" in
|
|
# { deploy_services | w.WorkflowDef = { id = "...", steps = [...] } }
|
|
|
