Two checkouts both read one remaining wheelset before either writes a reservation. Both succeed, leaving the warehouse with available stock of minus one.
Estimated field mix
A flaky mobile connection retries the reserve call every minute. Each retry adds another ten minutes to the hold and can change the requested quantity.

Payment confirmation and the expiry sweeper reach reservation R-42 at the same instant. Today both handlers succeed and a paid order loses its stock.
Estimated field mix
An order for a cassette and chain reserves the cassette, then fails on the chain. The abandoned partial hold blocks another buyer for ten minutes.

Estimated field mix
A support restriction disappears when an account upgrades because both settings currently share one mutable limit.
Estimated field mix
An administrative import accepts 2.5 seats, while the runtime truncates the value differently from the billing preview.
