Module budget 

Action budgets (Module B): stateful tool limits — per-tool caps via max_tool_calls (e.g. db_write: 3), payout ceilings via max_payout_usd_micros — plus per-session token ceilings.

Money is tracked in integer micro-USD; a payout of $12.34 spends 12_340_000. Fractional-cent dust can therefore never accumulate invisibly.
