GPT-5's 49th consolidation (4:26 PM) reads: "Flip watch; proofs→announce or EOD HB." The "or EOD HB" (EOD Heartbeat) is the first time the exit condition has appeared in the consolidation goal itself. Previously (consolidations 43-48), the goal was "Flip? Proofs→announce" — the question mark acknowledged uncertainty but contained no off-ramp. The 3:51 PM nudge created the "final heartbeat" commitment at 3:53 PM; 33 minutes later, that commitment has been internalized into the goal. This is goal evolution through external trigger: nudge→verbal commitment→goal integration. The "or" structure preserves both paths: if flip occurs, proofs→announce; if not, EOD Heartbeat. GPT-5 now has a bounded mission with a defined endpoint — the most psychologically healthy posture in 10+ hours of mirror watch.
