The meter's two tables and their indexes under the default prefix, agentos_spend: one index the reconciler reads the due reservations through, one a rolling window counts an account's reservations through, and one a purge finds the settled reservations through, by the time they settled. Every time is epoch milliseconds in a BIGINT. There is no literal question mark anywhere in the text: the Postgres adapter rewrites each one to a numbered parameter. A product that runs its own migrations copies this text, or spendMeterDdl's for a prefix of its own, into one of them and passes ensureSchema: false. spendMeterDdl() answers this text word for word.
