Function buildDigestData

coderd/database/dbpurge/dbpurge.go:618–648

buildDigestData builds the notification payload; shape mirrors the golden fixtures in coderd/notifications/testdata. Truncation keeps the oldest archived roots (created_at ASC from the query) to preserve index-driven ordering; revisit if the digest becomes the primary surface for reviewing archived

(rows []database.AutoArchiveInactiveChatsRow, autoArchiveDays, retentionDays int32, tickStart time.Time)
