Planning Cycle
The cadence axis of a plan: a dated interval a team plans in, be it a sprint, iteration, quarter, or program increment. cadence_kind classifies its granularity in methodology-neutral terms (period for a coarse container, iteration for an execution box, buffer for cooldown slack) while cadence_label keeps the team's own word for it. Cycles self-nest, so fine iterations sit inside a coarse period to form a granularity ladder. Objectives scope to a cycle and stories schedule into it by deliberate links, not containment: a story keeps its feature or epic parent.
