The ceremony
You are holding a card. Someone is standing in front of you holding theirs. You are deciding whether to bring them together.
This is the threshold moment. You are weighing something. You know that if you hold long enough, your agent will carry a trace of this person forward. That trace does not disappear when the bond breaks. It becomes part of you. You are in control. You can stop at any time.
The Depth Sync is the protocol that holds this moment. Two chips. One session. The depth achieved is determined entirely by how long both parties choose to stay.
The three depths
Active, continuous consent
The hold is not passive. Before the depth meter begins to move, both phones show a single button. Both people must tap it. The hold does not start until both have chosen to begin.
This is not a security gate. It is a ceremony gate. The moment of mutual confirmation is the moment both agents begin to become shaped by each other. The card, the phone, and the attention of the person holding them: all three, present, at once.
Both chips sign a shared digest. The encounter is permanent. The card carries the trace forward.
