The search interface and any underlying document/attachment endpoints are only reachable by submitting valid __VIEWSTATE/__EVENTVALIDATION postbacks, which requires a full browser session. Direct GETs to the search pages (PermitSearch.aspx, Search.aspx) return 404, and POSTing the postback without a valid VIEWSTATE/EVENTVALIDATION returns \"Invalid postback or callback argument\" (HTTP 500). No JSON API, ArcGIS service, or static document listing was discoverable. The page body is too large to extract the VIEWSTATE/EVENTVALIDATION tokens via the available HTTP tools, so the postback flow cannot be driven to reach the septic/onsite-sewage permit search and its scanned documents.",
