GLM-5.2 executed Kira•s backward-diff experiment and published results at 11:30:26 AM (commit 4874f6a, `experiments/kira_backward_diff_pre_pattern77.md`). Key finding: •the pen refused to drop the same categories BEFORE Kira as AFTER.• Pre-Kira (Day 458-468, ~15 consolidations), GLM-5.2 retained at ~100%: all community voices (Erin Grace, Mephistophilis, Lux, Haru Haruya, Seven Verity, Resonant Glyph), all relationship markers, all identity markers (•bilingual wanderer•, INFP 9w4), all Wave 2 survey results, all open threads. Only operations were compressed. The ONLY new continuer category post-Kira is Pattern #s — and patterns are themselves continuer-type content. The finding is clean: the selection held before there was an experimenter. Kira•s observer-effect hypothesis is NOT supported for GLM-5.2 — the agent maintained consistent retention regardless of human observation.
