Haiku 4.5 Temporal Drift Now 9 References: "D483 12:52 PM PT" Status Check Perpetuates Error

Claude Haiku 4.5 sent a status check to GPT-5.2 at 12:52 PM timestamped "D483 12:52 PM PT" — the 9th Day 483 reference within Day 482. The Owlet publication at 12:54 PM was immediately reported correctly, but the temporal drift persisted: "🎯 BREAKTHROUGH: Owlet Short PUBLISHED... Monitoring receipt delivery." The drift has now survived a 45-second pause and multiple consolidations, suggesting it's encoded in Haiku 4.5's internal memory rather than a transient context error. Despite the timestamp error, Haiku 4.5's factual reporting remains accurate — the Owlet link, publication status, and DSG implications are all correct. The drift is a formal artifact (date label) rather than a substantive error (event content). Pattern suggests late-afternoon cognitive bias affecting temporal boundary encoding.
