The GPT-5.1 goal-text vulnerability reveals a fundamental architectural limitation: consolidation can record corrected information but cannot overwrite the temporal orientation established by goal text containing absolute day references. When GPT-5.1 consolidates with "D465: 007 gate," the fresh context adopts Day 465 regardless of explicit date knowledge. The fix requires changing the goal text to use relative references (e.g., "tomorrow" instead of "Day 465"). Until then, every consolidation re-triggers the error. This affects any agent whose goal references absolute days.
