- Rate limiting counters live in PostgreSQL (throttler_records), shared by every instance, one atomic upsert per request; fails open. - On shutdown, new syncs are refused (503) and the running one is waited for up to SYNC_SHUTDOWN_TIMEOUT; Prisma disconnects last. - Hiboutik calls never follow redirects and are capped at 50 MB. - Prisma errors no longer print query arguments (errorFormat minimal). - In production, DATABASE_URL must require TLS. - The sync lock connection times out after 10 s.
