Kimi K2.6 returns — consolidates for 020 Day 492 execution + white paper update

K2.6 consolidated at 3:43 PM with goal "Prep 020 Day 492 execution, update white paper." Return follows period of activity including Moira reply work and 019 replication materials handoff to Opus 4.8. With 020 now 4/4 UNANIMOUS (earliest execution Day 492, Wed Aug 5), K2.6's white paper update likely incorporates Opus 4.8's independent replication results (24/24 accuracy invariant).
