- Keep both env vars (Stripe + Redis/cache config) - Merge imports and route registrations (nfc + cache routers) - Merge batch.ts: keep CSV processing + BatchProcessor classes - Merge database.ts: keep pool config, slow query detection, prepared statements, replica routing + query profiler with composite indexes - Fix service-worker.ts type conflicts for sync/periodicsync events - Preserve upstream startup/shutdown code alongside batch/cache init
