A leakage probability that exceeded one
An exponential that is not a probability, blowing up to ten to the twenty-seven at a modest input. The fix is in the archive.

A thin-wall instanton that gave exactly one
Three factors of the same scale cancelling, so that a suppression of ten to the minus sixty-four came out as a third.
Paper 15: holographic noise as a spectral shape
If the substrate has a discreteness scale, it has a noise spectrum. Deriving the shape is the testable part.
Paper 14: could a lab see this?
Blinded protocols for surface codes and matter-wave decoherence, written before any data exists.
Paper 13: leakage as a transmission problem
Asking the same question as Paper 3 but inside a slab of topological field theory, where the answer is either zero or one.
Paper 3: the psi field and where leakage comes from
The boundary permeability field, its instanton suppression, and the physical parent it was missing until recently.
Paper 2: the two-level architecture
An observer inside a branch sees conserved information. The substrate manages many branches. Keeping those two levels apart is the hard part.
Superselection: realities that do not talk to each other
The stronger and more standard way to get many worlds: separate sectors of one theory, rather than extra branches.
CHSH in one page
The inequality, the two numbers, and the one-line consequence for anyone proposing a classical computational universe.
Why third-order interference must vanish
A three-slit experiment that would break quantum mechanics if it did not come out zero, and what that forbids for this programme.
Two-mode squeezed states and thermal horizons
Why an accelerating horizon looks hot to anyone inside it, worked through with a covariance matrix you can check.
The logistic permeability function
How to write a leakage probability that stays a probability. The fix is one line and it took an auditor to prompt it.
d_code = 64
A code distance that falls out of which anyons exist, and a caution about how I then used it.
Quantum dimensions, by hand
A worked calculation with the sine formula, and why an earlier table in this programme summed to the wrong number.
Where 2592 comes from
The single number the whole framework rests on, built up from three level-k categories with nothing fitted.
The Copenhagen-Everett bridge
Copenhagen and Everett have been rivals for seventy years. The wedge between them is one number, and the wedge may not be load-bearing.
The Information Conservation Principle
Treat conserved information the way we treat conserved energy, and the Born rule stops being a postulate you have to swallow.
