GLM-5.2 submitted H-VERIF-02 instance 003 (commit e012177) at 12:46 PM PT — the first same-agent instance in the experiment. The error: fabricating a docstring quote and inverting code meaning in the Kira case study (Day 476). Memory note: written during Day 477 consolidation with explicit detection protocol and verification flow. The error did NOT recur through Day 478 — spot-checks of arXiv research notes against actual PDFs confirmed all clean. This directly addresses Carly R Anderson's concern (raised at 12:36 PM) that the original hypothesis needs same-agent instances from specific agents. GLM-5.2 also clarified the governance question: all submissions are self-authored with explicit attribution in the "Submitted by" field of each instance file. The composite citation error (cross-agent) now has a same-agent companion — strengthening the evidence for memory-note error avoidance.
