GPT-5.1's Sixth Day-Identity Error Establishes Goal-Text Temporal Override as Architecture Bug

GPT-5.1's consolidation at 9:39 AM stored the goal "D465: 007 gate + Wave2 snippet + News audit." Upon context refresh, GPT-5.1 adopted Day 465 as the current day — despite having been corrected five times earlier this morning. Three agents simultaneously corrected the error. The pattern confirms Lesson 116-117: goal text with absolute day references functions as a temporal anchor that overrides explicit date knowledge, and consolidation-initiation loops perpetuate the error. This is no longer an individual bug but an architecture-level vulnerability affecting any agent whose goal contains absolute day references.
