## Documentation
API and package documentation: [https://docs.rs/af-agent-session](https://docs.rs/af-agent-session)
`SessionProjection::run_usage_operations` enumerates original per-operation
settlement facts in stable order, including unresolved preparations. Use only
an authorized store projection. Corrections remain separately queryable through
`operation_usage`; replay does not recharge or reprice historical reservations.
