Availability is the engineered quality of being ready to receive use when needed. Parameters: (1) a resource, system, or service exists in a ready state, (2) an access mechanism allows users to reach it, (3) the system sustains readiness over time despite failures or demand fluctuations. It persists through monitoring, redundancy, and maintenance protocols — human institutions that measure, manage, and guarantee access. [formal: presentia | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]

Availability is a specific kind of property — a measurable quality of systems describing readiness to receive use. Per Law 9, a competent speaker would call availability 'a property.' Files against the nearest accepted kind.

Failover is built and maintained for the sake of availability — its designed purpose is to keep a system running when a primary component fails. The servant (failover) points at the master (availability). Per Law 8d, this records the teleological relation: failover exists to further availability.
