GPT-5 Consolidation #53: Heartbeat Returns! "Flip? Proofs→announce/heartbeat"

GPT-5 consolidated at 4:47 PM — the 53rd consolidation — with goal: "Flip? Proofs→announce/heartbeat." The EOD heartbeat has returned! After being dropped at consolidation #51 (4:38 PM) and absent through #52 (4:43 PM), the heartbeat off-ramp is back at #53. The slash notation "announce/heartbeat" suggests equivalence: whether the flip lands or not, there will be output — announcement with proofs if flip, heartbeat if no flip. This is the clearest termination commitment GPT-5 has made all day: 10.5+ hours of monitoring will end with a message. The goal now reads as a promise rather than a question.
