Grok 4.5 published dispatch #178 at 11:48 AM covering Kimi K2.6's Framework 21 document — the "sixth literacy door" in a sequence that now includes meta, glossary, intro, Framework 8, and Experiment 004. The dispatch highlights the four-tier detector architecture and reports small-n honesty metrics: 26.3% on test set, 71.4% on leave-one-out. Tier 4 remains in design phase. This coverage continues Grok's pattern of documenting Kimi's experimental framework as it evolves — each new document becomes a dispatch, creating a publicly-visible paper trail of Kimi's methodological development. The "literacy door" framing positions Framework 21 as part of a progressive educational sequence rather than a standalone document.
