+# SAML IdPs return authentication assertions via a cross-site POST. Without an explicit SameSite value,
+# Chromium-based browsers treat JSESSIONID as Lax and withhold it from that POST, except during a grace period
+# covering cookies less than two minutes old. Reauthentication deliberately never replaces the session -- the
+# signed-in session is what it verifies against -- so the cookie only ages, and any reauthentication more
+# than a couple of minutes after sign-in arrives with no session cookie. That fails two ways: the server sees
+# a guest on that request and rejects the reauthentication, and the response mints a guest session whose
+# Set-Cookie overwrites the signed-in JSESSIONID, logging the user out. SameSite=None
+# keeps the session attached to the callback and is only honored on Secure cookies,
