Module usage 

Structs

ComputeTotals

Aggregated compute totals for a usage window.

SessionCounts

Raw backtest_session_* point counts for this api key in the window, by outcome — not session-deduplicated, so the three need not balance (a pre-start failure has no started; a cross-manager handoff re-emits started). Billing uses the compute totals, which derive only from the terminal completed/failed points.
