IndexNow proof-origin protocol fix
Production Bing validation exposed HTTP 500 at the external root proof because TLS termination was followed by an internal rewrite using the wrong protocol. This release corrects that rewrite boundary, but remains unverified until the external proof returns HTTP 200, the automatic submission runs, a later canary returns HTTP 200, and the idempotent rerun passes.
IndexNow root-proof request compatibility
After v4.3.3, the exact root-level {key}.txt proof returned HTTP 200, but a full request carrying keyLocation still returned HTTP 403; a minimal homepage request with the same production key and no keyLocation returned HTTP 202. This release omits that field, while the automatic full run and idempotent rerun remain deployment checks.
IndexNow key-proof compatibility
Changed IndexNow verification to the official root-level {key}.txt convention after the first production notification returned HTTP 403; revalidation remains pending, while the website, sitemaps, and Bing sitemap processing are unaffected.
