Recognising regular statements, surfacing account changes · Gmail Bot devlog

The bot learns each sender's usual subject lines, with amounts and dates stripped out, so a monthly statement from a known sender passes straight through. A known sender suddenly writing something off-pattern gets flagged for a look.
Notices that something changed on an account ("you switched…", "you shared…", "you granted…") now have their own security-sensitive treatment and are never cleared automatically.
The "new sender on a sensitive topic" check reads only the subject and preview, so standard footer text no longer sets it off.
