matrix d — why protos are orbs
a proto is not just a schema sketch. it is the place where a world grants semantic residency. that is why the anchor works better as a glowing orb:
membrane
outside material stays outside until the membrane admits it. the orb says “local meaning starts here.”
bay
the shell implies intake bays, lookup sockets, birth rules, and relation spokes, not a flat dead document icon.
keyspace
a resident epi lives in a keyspace. the orb visually holds those residents and their identity rules.
fractal repeat
interfaces compose into ports; ports into faces; faces into orb bays; orbs into bridges and tracks. same grammar up and down.
