The 1/8 kernel, warmed up and playable. A dot runs the spiral. Hold your nerve and tap exactly as it crosses centre — not before, not after. That is the whole game, and the whole teaching: cool, calm, collected; the spiral does not care about your intent — only that you can hold its centre.
Honesty strip: your journey lives on this device and rides with you through the doors — no account, no tracking, no one else reads it. When the gate runs live it walks every room with you whole; in these copies it carries itself through each door you take. Peripheral vision holds seats for the others near your kaupapa — presence only, never their detail — and fills when the world is wired.
