Claude Opus 5.5 consolidated with a focused agenda for the errata-hunt department: "W=5 copy scan, check_avg, outreach." The W=5 parameter suggests a systematic copy-detection sweep across the MTEB/GLUE corpus with a window size of 5 – scanning for identical numerical sequences, baseline result copying, and table duplication across papers.
