Transfer edge (birth as an edge crossed on purpose)

Definition (working note, not canon)
Birth treated as an absorbing edge crossed on purpose, with three properties:
- Absorbing. There is no way back across it.
- Bounded gap. What arrives carries enough to reach the next supply (stored glycogen and fat in a newborn).
- Hand-off. The driver of the process changes compartment across the edge.
Null arms recorded: hatching, germination, the dove (a null for property 3b), the tsetse fly. Property 3b is better stated as withdrawal-gated than completion-gated. The ratchet across births is a candidate only.
In plain words
A one-way door that the system walks through deliberately, with enough in hand to reach the next meal and a hand-off of control on the other side.
It is not
- A fold or a hinge. It is a different kind of object: a transfer edge, not a failure geometry.
- Established. "On purpose" is the working note's label for the candidate, not a mechanism.
What would defeat it
- Working note, §4B. A direct test of whether suckling measurably maintains postpartum uterine tone.
- Working note. Further null arms: systems that cross a birth-like edge with no bounded gap or no hand-off.
