sdg:IntervalCopy as claim

sdg:Interval is the value of sdg:scheduleKind for scripts that run on a fixed cadence: every sdg:intervalSeconds seconds, the registry reruns the script and overwrites its output graph. Consumers read the result as eventually consistent, stale by at most one interval.Copy as claim

Interval scheduling suits pure, full-recompute scripts like the inbound-reference-counts metric: deterministic, rebuildable from the authoritative graph, cheap enough to redo wholesale. Incremental, event-driven recomputation is the hook-plus-script pattern planned for Phase 4.Copy as claim
