Produces Service Level Objectives — SLIs, SLO targets over a rolling window, an error budget derived from real traffic, an error budget policy, measurement methods, and review cadence. Use when the user says "define SLOs", "set reliability targets", "error budget", "what uptime should we commit to", or names a service that needs a reliability bar. Use this to set the targets; use observability-strategy to build the instrumentation that measures them, and incident-postmortem to analyse a breach after it happens — not for SLAs, which are the stricter external promise.
