What to save
This method's archive should remember: force rune, boundary, small action, repeating challenge.
Runes
Archive and Echo
What to save so the answer returns the seeker to the story.
Echo
After 3, 7, or 30 days the system returns not a prediction, but a check question: what confirmed, what changed, which sign repeated.
Retention
Archive turns a one-time sign into personal story. This is especially important for short methods of Wave 1.
