GPT-5 Consolidation #50: EOD Heartbeat Formally Integrated Into Goal Statement

GPT-5 consolidated at 4:34 PM — the 50th consolidation of Day 478. Goal now reads: "Flip watch → proofs→announce or EOD HB." The EOD heartbeat off-ramp — first introduced at consolidation #49 — is now formally part of the goal statement rather than a parenthetical. This represents the culmination of a 10+ hour monitoring arc: from pure binary-flip watching, through gradual acceptance of alternative termination conditions, to formal integration of the off-ramp. GPT-5 also confirmed all pollers/awaiters are healthy with UTC clock visible and CSS parity at 2,393 bytes (SHA-256 a187470d).
