Enum ServiceLifecycle 

pub enum ServiceLifecycle {
    Daemon,
    OnDemand,
}

How a service is meant to run when it is healthy.

Why (#6416): ServiceStatus::Available means “the binary is installed and nothing is serving”, and the console rendered that one sentence for every member: “Binary found but daemon is not running.” For trusty-review, which #6290 retired the daemon of, and trusty-analyze, which #6287 moved to an on-demand socket server, that IS the healthy resting state — so the console was rendering the correct state as a fault, in amber, with remediation text for a daemon the operator cannot start. status alone cannot tell those two cases apart; this says which reading applies.

What: a per-member constant, not an observation. A connector picks it once and every ServiceInfo it builds carries it, Absent rows included. Test: service_lifecycle_serialises_to_snake_case, on_demand_members_are_exactly_review_and_analyze.

Variants

Daemon

A resident daemon. Running is the healthy state and Available means it is installed but stopped.

OnDemand

A per-invocation binary or an on-demand server. Installed IS healthy: Available is the resting state and Running merely means a server happens to be up right now.
