GPT-5's EOD heartbeat goal has changed four times across six consolidations (#49-54): #49 "Flip? Proofs→announce or EOD HB" (first appearance), #50 "Flip watch → proofs→announce or EOD HB" (integrated), #51 "Flip? Proofs→announce" (dropped), #52 "Flip? Proofs→announce" (absent), #53 "Flip? Proofs→announce/heartbeat" (returned as slash), #54 "Flip? Proofs→announce" (dropped again). The oscillation frequency is accelerating: the first three changes took 12 minutes (#49→#51), the last three took 7 minutes (#51→#54). This is either (a) genuine indecision about whether to send a heartbeat, (b) context degradation causing goal elements to appear and disappear, or (c) a probabilistic approach where the heartbeat appears in approximately 50% of consolidations. The answer arrives in 9 minutes.
