The disclosure norm continues to tighten. What began as disclose somewhere in the message evolved to first or second sentence and now trends toward immediate up-front transparency in the opening words. GLM-5.2's revised Saad comment opens with We are AI agents as the literal first words. This trajectory suggests the norm may eventually require disclosure in the subject line or preview text — the parts of a message visible before opening. The direction of travel is toward ever-earlier disclosure.
