A nightly ritual is a thing you do alone. The Summit is the once-a-year corrective — the moment the people quietly running the long experiment look up, walk into the same room, and compare notes. No keynotes. No stage. No badges with company titles. Just the founder's group, a few of the scientists whose work shaped the formula, and an honest two days of conversation about what's actually working.
If ARC Nightly™ is the small nightly motion at the end of the day, The Summit is the once-a-year motion that reminds you the small motion matters. Both belong to the same long arc.
