#://SiTex — Build on CNXT from ChatGPT Sites — CNXT

The operating doctrine for the ChatGPT Sites dimension — three connection patterns (server-side /api/v1 with the key only in the Site's hosted secrets, anonymous THeoPeNAiDesK reads, per-visitor CNXT identity through first-party OAuth with PKCE), the identity boundary (a header a Site can set is a header CNXT cannot trust), the money boundary (nothing settles, mints or moves treasury from a Site), and the observed-not-guessed callback-host rule with its RFC 7591 refusal vocabulary.
