# X_PARTITIONS_UNMAINTAINED

## Means

a partitioned entity with no partitions() job

## Typical cause

An entity declares partitionBy and no partitions() job from @ultimat3/jobs is registered: no partition is ever created ahead, so the first insert past the last migrated partition fails in production, and retention never drops one

## Fix

`x verify --only manifest --json` — after exporting partitions() from @ultimat3/jobs in a module listed under jobs in apps/web/api/index.ts, and its .schedule under tasks
