# X_INSTRUMENT_SLOT_ALLOWANCE_STALE

## Means

an `INSTRUMENT_SLOT_ALLOWED` row excuses nothing

## Typical cause

the row in `scripts/instrument-slots.ts` names a `file#name` that no scanned file exports — the port was moved, renamed or deleted

## Fix

edit `INSTRUMENT_SLOT_ALLOWED` in `scripts/instrument-slots.ts` to drop or rename the row, then `bun run scripts/instrument-slots.ts --json`
