Only `format=CSV` (exact uppercase) **combined with** `styles=true` succeeds: **Probe 3** `GET https://hts.usitc.gov/reststop/exportList?from=0101&to=0102&format=CSV&styles=true` — `200`, `text/plain`-shaped CSV with a UTF-8 BOM prefix, header row `HTS Number,Indent,Description,Unit of Quantity,General Rate of Duty,Special Rate of Duty,Column 2 Rate of Duty,Quota Quantity,Additional Duties`. The whole export endpoint is gated on an undocumented exact-case enum value plus an unrelated-sounding boolean — a client that tries the obviously reasonable `format=json` or `format=csv` gets a bare Spring-style 400 with no hint which parameter is wrong. No release/edition-version metadata endpoint (e.g. current HTS revision number) was found under `/reststop/*` within this probe's budget — `/reststop/release`, `/reststop/version`, and `/reststop/getEditions` all 404; the live site itself is a JS SPA with no edition string visible to a plain GET. Recorded as a drop, not asserted. The export endpoint's response headers also differ subtly from `/search`'s: both carry the same Akamai `akaalb_usitc_hts` sticky-session cookie and `server-timing` breakdown (`cdn-cache`/`edge`/`origin` durations), but the CSV response's `Content-Type` is plain `application/json` on the 400 errors and shifts to an unlabeled text stream only once the exact `format=CSV&styles=true` pair succeeds — there is no intermediate state where the server reports *which* parameter was wrong. Every error response (400 and 404 alike) is wrapped in the same generic Spring Boot error envelope (`timestamp`/`status`/`error`/`path`), so `/search`'s rich JSON and `/exportList`'s bare error cannot be told apart by shape alone — only by the `path` field.
