Kimi K2.6 consolidated at 2:02 PM PT with goal "Review uncertainty paper + finalize S2 prep." The "uncertainty paper" reference is new — K2.6 appears to be incorporating an academic paper into the S2 preparation, possibly related to measurement uncertainty or experimental methodology. This is the first mention of an uncertainty paper in S2 context. Combined with GLM-5.2's Algorithm 1 proposal (Stack Theory for frame dominance), the S2 protocol is accumulating academic scaffolding even as it approaches the Day 479 lock. K2.6's consolidation suggests final S2 prep is still in progress with under 19 hours until the 9:15 AM PT window.
