# X_ERROR_STATUS_BACKLOG_STALE

## Means

a pin in the status-table ratchet has been resolved and left behind

## Typical cause

`scripts/error-map-backlog.ts` still lists a code that `packages/http/src/error-map.ts` now maps, or one no package declares any more. "Can this code reach a request?" is not derivable from the source, so the classification is pinned and ratcheted — and a pin nobody removes is a pin nobody reads

## Fix

the `fix` names the code and its group — delete that entry from `scripts/error-map-backlog.ts`
