Audit log & budget
When the question is "what happened, and what did it cost?", two console views answer it: the Logs — the tamper-evident event record — and Budget, the spend it accrued.
Logs
Logs is the cross-session audit: approvals, authorization decisions, tool calls, and scope changes, filtered
by kind, outcome, agent, or tool. It's the read side of the tamper-evident log — the same signed,
hash-chained records oap audit verify checks offline — surfaced for browsing rather than verification.

Budget
Budget breaks down estimated spend by model, agent, session, and user — a running total (list-price estimate) that resets daily. It's the console view of the same accounting the per-session budgets enforce.
