Ai Review Evidence

Worker init injects that vlog into SyncManager, so account setup on worker start is sent outbound.

High

Ai Review Evidence

android-bootstrap.ts init sends JSON.stringify(account.imap) through that logger; that object includes the IMAP password.

High

Ai Review Evidence

addAccount logs account email and IMAP auth details to the same host with no opt-in.
