Crossover Services Overview (Group 11)
The live crossover/depository surface for reserving exchange lockers, checking deposits, withdrawing, and reading exchange rates.
Overview
Group 11 is the live exchange-oriented command family. It centers on a depository/locker workflow: reserve a destination, verify incoming external value, withdraw against the depository state, and query the current exchange rate.
Per-command pages: 110 reserve_locker, 111 check_depository, 112 withdraw_from_depository, and 114 get_exchange_rate.
When to use which command
A typical crossover flow starts with reserve_locker to allocate the exchange-side destination, polls check_depository until the expected external value arrives, then settles with withdraw_from_depository. get_exchange_rate is an independent read that callers use to display or gate rate-sensitive decisions; keep it separate from the reserve/check/withdraw orchestration in client code.
Live surface note
The active audited Group 11 set contains 110, 111, 112, and 114. The documentation intentionally does not elevate other historical crossover ideas into the live reference set.
