Upload & Preview

Files are previewed and validated in the browser. Uploaded files are private in Cloud with size/type limits and no public buckets. Do not write unvalidated rows or partial failed uploads. Prevent duplicate dates and same-ID changed payloads. Preserve all historical rows.

This page is preview and validation only. The persist action is intentionally disabled: it has no save handler, and this CSV template supplies only obs_count_3y — a typed sample count — not the actual ≥150 weekly observations over exactly three calendar years required to verify a COT series. A successful membership lookup is not proof that imports work. Browser-selected files are validated locally; they are not uploaded to private Cloud storage from this page. Actual protected server validators and durable, atomic, idempotent import require the connected atomic backend and an authenticated server write — not enabled here.

Disabled pending the connected atomic import path. You can download templates and review validation now; persistence accurately requires the connected backend and an authenticated server write. No current financial/user data has been supplied — do not seed it.
