a guessed bulk-download file path that doesn't exist falls back to rendering the live portal's homepage HTML, also `200`. None of these hosts is unusual in isolation — each probably considers its behavior a reasonable application-level design choice (lenient querying, soft-404 UX, a complete-but-empty schema). The pattern across four unrelated agencies and vendors is what matters: for public US government hydrology/offshore-data infrastructure, **"no error" is not evidence of "found something,"** and any agent integrating one of these APIs needs an explicit payload-emptiness check (null fields, zero-length arrays, or a known error-page byte signature) rather than relying on the transport-layer status code at all.
