Spend adds up on one ledger. Charged this month has one definition, price less discount, included usage and credit, shared by the plan card, the spend limit, Spend and the top bar; the limit had counted usage not yet closed at full price before the discount, so a comped workspace read as charged a cent. Every agent line on the ledger names the agent and who asked, repository runs by g1t included, so Spent is the sum of its products, Agents is the agent product, and by agent adds up to it; the billing API returns by_agent and by_person. The usage and billing guide says how spend is counted.383/** An agent run's meter: g1t's own agent at work, for the person who asked, so its sandbox time is attributed with the rest of the run. */

Spend adds up on one ledger. Charged this month has one definition, price less discount, included usage and credit, shared by the plan card, the spend limit, Spend and the top bar; the limit had counted usage not yet closed at full price before the discount, so a comped workspace read as charged a cent. Every agent line on the ledger names the agent and who asked, repository runs by g1t included, so Spent is the sum of its products, Agents is the agent product, and by agent adds up to it; the billing API returns by_agent and by_person.
