 ## 2025-12-20 — Migration history repair
 - Restored missing migration `20251212_agent_billing` (agent billing columns + listing billing settings table) so Prisma history matches the DB.
 - Reconciled test DB migration history: aligned checksum for `20251212_agent_billing` and marked `20260310_site_settings` and `20260311_billing_preferences` as applied to stop Prisma errors and surface listings again.
+- Applied the same agent billing schema to staging/prod DB (`lomavuokraus`) and marked the migration as applied; Prisma status now clean there too.
+- Deploy script now runs a Prisma migration status preflight using DATABASE_URL from env or in-cluster secret and fails fast on drift before applying manifests.
