Admin only, every action. It reads and never writes. A field an agent did not state is null, never 0. action "aggregate" (the default) returns, per agent and namespace, jobs and claims, each evaluation's agree, disagree, unclaimed and unchecked counts, and the touches by kind and actor kind with the total and median wait; filter with namespace, agent (an actor string such as agent:sample-driver), since and until (ISO times). action "job" takes id and returns the job, its job_outcomes row, and its claims, evaluations and touches, oldest first. action "export" takes table (${CLAIMS_EXPORT_TABLES.join(" | ")}), after (the cursor, 0 to start) and limit (at most ${CLAIMS_EXPORT_MAX}), and returns rows as stored with next_after, the cursor for the next page, or null at the end. The cursor is id, or rowid for job_outcomes.`,
