# What is an inventory cap?

An inventory cap limits how many of a package can be sold or issued. It is optional. When set, it is enforced against the ledger rather than a counter that can be edited, so the number sold and the number recorded always agree.

A cap is how a venue sells something genuinely limited without overselling it.

## Enforced through the ledger

Consumption is a ledger entry, not a decrement on a field. That is what makes
the count defensible when somebody asks how many were actually sold.

## Corrections are recorded, not silent

Releasing or correcting used inventory requires the right permission and an
explicit operator note. There is no control anywhere that changes inventory
without leaving a record.
