The Run Ledger
Store an agent run so it can resume, be billed and be audited, and know when to split the store.
Key idea
An agent's state comes in four kinds, and most of it fits in one Postgres. The ledger is the set of tables that makes a run resumable, billable and auditable. Split the store only when a measured number says so, and write that number down before you split.
Four kinds of state, and one store until a measured number says otherwise
Purple: state. Teal: the store this lesson is about. Dashed: disposable.
