Distinct from fake-mychart-patient-portal-breach-lure (iter 934) which requires breach notification language; this signal fires on portal-access urgency with no breach narrative required — \"your MyChart session has expired and your account will be deactivated within 24 hours — sign in now to keep access\" or \"Epic patient portal: your account requires re-verification to maintain access.\" MyChart is the patient-facing portal for Epic, the dominant hospital EHR system (250M+ US patient records). The signal fires when: (1) body references MyChart, Epic patient portal, Follow My Health, or similar patient portal brand AND (2) portal-access expiry, session expiry, account deactivation, or forced re-authentication urgency is present AND (3) sender is NOT from mychart.com, epic.com, or any of the 25+ major health system domains AND (4) no List-Unsubscribe or In-Reply-To.
