What a Switch Window Is
A switch window is a timing concept: a span when shopping multiple carriers may be more valuable than waiting. The engine assigns open, monitor, or closed status from precomputed rows.
Open vs monitor vs closed
Open may indicate favorable timing to compare before renewal. Monitor suggests watching the index for updates. Closed suggests less advantage from waiting — still compare if your renewal is imminent.
Aligned with alerts
Alerts use a shorter horizon (14 days) while index pages use 30-day overlays. Wording stays consistent because both read the same decision store.
