/**
 * `cleo doctor exodus` core — read-only exodus health report (T11837).
 *
 * The fleet pre-check the owner flow opens with: a single, read-only snapshot of
 * where each scope stands so an operator (or the rollout automation) can route
 * the next step — already-sealed, migrated-but-unsealed (→ `cleo exodus seal`),
 * fresh-needs-migration, or no-cleo-data — and so any LARGE legacy DB is flagged
 * for individual attention before the streamed-verify build touches it.
 *
 * Pure assembly over existing primitives (`buildExodusPlan`, `runExodusStatus`,
 * `hasExodusCompleteMarker`, `detectStrandedResidue`, {@link computeCountParity}).
 * Never writes; never runs the heavy digest.
 *
 * @task T11837 (fleet-flow surface — exodus health-check)
 * @epic T11833 (EP-EXODUS-FLEET-HARDENING)
 * @saga T11242 (SG-DB-SUBSTRATE-V2)
