// Regression guard for #46761 / PR #47395: Photon (iMessage) must keep its own
// sidebar section. refreshMessagingSessions() filters rows through
// isMessagingSource(), so this entry is the sole condition that keeps Photon
// sessions out of generic recents. A silent removal would regress the feature
// with no test failure — these asserts pin the contract.
