/**
 * Digest summary types — the aggregated trend shape a scheduled sweep
 * formats and delivers.
 *
 * These live in the domain kernel (not in `packages/eval`) so the
 * notification port (`ports/notification.ts`) can describe a digest payload
 * without core depending on eval. The eval digest *engine*
 * (`packages/eval/src/schedules/digest.ts`) computes and re-exports these
 * shapes; the dependency flows inward only (D0002 / D0045).
