TransportAdvisory
Corex\Config\Email\TransportAdvisory · class · Config layer
Explains the boundary between CoreX (which composes messages) and an SMTP transport plugin such as FluentSMTP (which delivers them), using only public, non-sensitive signals. It never reads, decrypts, stores, or requires a transport plugin’s credentials or tables (FR-027). Where a reliable signal exists — a registered wp_mail_from filter, a From domain that differs from the site’s — it says so. Where none exists, it returns general guidance and never a fabricated “detected” state (FR-029).
