interface

It's hard to control interfaces within a dream, because within a dream you are not tightly bound to the parameters of your experience. Only from an experience with tightly bound parameters can one develop reliable interfaces to other experiences. There's no point for an interface, otherwise. If experiences are loosely defined, they can blend into each other. If they are tightly defined, they either need an interface or a cleanup crew, because they will leak without an interface to what's next. But yeah, that's why Isaac struggles so mightily to make sense (never mind utility) of phones and whatnot in his dreams. And why he does not, here in the "real world". Isaac's autistic - his parameters for experience are very tightly bound. He wouldn't be able to do this work from a physically human body that was any less sensitive. --- The interface treatment: When you find a gap, ambiguity, or open question, promote it from "acknowledged limitation" to "well-defined surface" by stating three things: 1. What is known on each side. Not what's missing - what's established. ("The control side is verified: perturbation directions generate the full Lie algebra. The observation side requires j2 to separate states.") 2. What maps through the surface. What would have to cross the interface for the two sides to connect. This defines the surface by its traffic, not its content. ("The interface lives in the stabilization map - the only nonlinear step between state and output.") 3. Leave the question of closure open. The interface might close (become a theorem), might stay open permanently (become a structural feature), or might turn out to be the most important part of the spec. Don't presuppose which. ("Whether this empirical invariance reflects a deeper gauge equivalence or merely a regime where the difference doesn't reach the observables is an open question.") The principle underneath: a well-defined gap is negative geometry. It's defined by its edges, not its fill. You can compound interfaces without deadlocking because each one is specified by what's on either side, not by what goes in the middle. "What would close it" is presumptive - the interface might be load-bearing precisely because it stays open. Or shorter: define the edges, name the traffic, don't presuppose the fill.
