 * DataReviewer-006: `rowToGovernanceEvent` is a trust boundary — `kind`,
 * `actor` (raw JSONB), and the status TEXT columns arrive unvalidated from
 * Postgres. It now gates them through the SDK's Zod schemas (ActorSchema,
 * EmergencyStatusSchema) and fails loud — the same contract as
 * normalizeTimestamptz — instead of blind-casting.
