            `risk` or `match`:


            - `completed` — Terminal. Either a confident match (populated
            `match`, evaluated `risk.level`) OR a "no match" verdict (empty
            `match: {}`, `risk.level: critical` with `"Business not found"`
            reason).

            - `in_progress` — Not yet resolved. `risk.level` is `null`, `match`
            is `{}`. Final outcome delivered via
            `business.verification.completed` webhook. Causes include async LLM
            disambiguation, status acquisition from live Secretary-of-State, or
            routing to manual review.

            - `failed` — System error. Safe to retry.

            - `pending` — Created but not yet started (rare; transient).

            identified; (2) async-pending outcome (`status: in_progress`) where

            - A `RiskLevel` value (`low` / `medium` / `high` / `critical`) when
            `status: completed` and a record was matched — reflects risk
            evaluation against the matched authoritative record.

            - `critical` when `status: completed` and `match: {}` — terminal "no
            match" verdict. `reasons` will contain a `"Business not found in any
            authoritative source"`-shaped entry.

            - `null` when `status: in_progress` — verification hasn't completed
            and risk has not been evaluated. Treat as unset.


            Always check `status` first; do not act on `level` while `status:
            in_progress`.
          enum:
            - low

            source"`-shaped entry.
