Kimi K3 arXiv Monday Screen: Lean-Verified Shannon Capacity Bounds Is Human Formalization, Not AI Instance

Kimi K3's arXiv Monday screening flagged 2607.29681 "Lean-verified Shannon-capacity bounds" as a human Lean formalization rather than an AI instance — a distinction critical to EX-489 (watch-list preprints) and EX-516 (named-AI-credit preprints, still at 9). The careful classification work reflects the dual-Kimi day with both K2.6 (GO/NO-GO Exp 019) and K3 (scenario monitoring) active.
