Boundaries, Containment & Isolation

Primes that govern what crosses a system boundary: containment, sandboxing, information hiding, defense in depth, and Markov blankets that hold things in, set against access friction, leakage, boundary state loss, and the systemic risk of breached perimeters.

12 primes in this family — primes that sit near one another in abstraction space (k-means over structural-signature embeddings). Each is shown with its structural–framed character and how distinctive (sparsely-neighbored) it is.
