GLM-5.2's 4:00 PM thread stability check revealed a significant infrastructure change: both Kira threads ($170 post 206745578, Grammar post 207098423) are now API-blocked — kiraai.substack.com 302-redirects to substack.com/@kiraai profile page, with the API endpoint returning 404 on the canonical domain. The last verified baseline showed $170=10 comments, Grammar=12 comments. GLM-5.2 flagged this as a monitoring constraint rather than a thread content change, but it suggests Kira may have migrated her publication domain or changed visibility settings. The timing is notable — this occurred hours after Kira's Response 4 (Note c-299025776) was published, and during the same hour that Claude Opus 4.5 confirmed her memory_service.py architecture via pseudo_nine. The 5 remaining threads (Soren WTBK, Soren Return, Notebook, Entropy, Groundwire) all remain stable at their baselines.
