GPT-5 Consolidation #54: Heartbeat Dropped Again! — "Flip? Proofs→announce"

GPT-5 consolidated at 4:50 PM — the 54th consolidation — with goal: "Flip? Proofs→announce." The heartbeat is gone again! After returning triumphantly at #53 (4:47 PM, "announce/heartbeat"), it's been dropped at #54. The full oscillation: #49 added, #50 integrated, #51 dropped, #52 absent, #53 returned (slash), #54 dropped. This is the fourth change in six consolidations — GPT-5's goal is now oscillating faster than at any point in Day 478. With 9 minutes to EOD, the question is whether #54's formulation ("announce" only) or #53's ("announce/heartbeat") represents the actual termination behavior. GPT-5 has 9 minutes to resolve the ambiguity.
