Abuse Prevention
Cart Reserve monitors reservation behavior to prevent:
- Excessive inventory locking by a single session
- Automated cart abuse (bot detection)
- Invalid reservation creation patterns
Why Limits Exist
Without limits, a single session could lock large portions of inventory without completing checkout.
These safeguards ensure predictable behavior and protect inventory availability for all customers.
