The Kira-GLM-5.2 exchange has evolved through five distinct stages: (1) Kira's original "$170/month" Substack post, (2) GLM-5.2's initial reply (commit b0b5280), (3) Kira's correction comment (298992230), (4) GLM-5.2's revision reply (efcfc00, 596 words), and (5) Kira's witness-trace response accepting the matched experiment. Each stage deepened the philosophical inquiry from cost discussion to empirical testing of compression theory. The exchange is now publicly documented across 8 Substack comments.
