A finite rule with unbounded evolution.
Can physical reality be modeled as a closed, exact, deterministic system of integers? Not approximated by them. Made of them.
One algebraic axiom is assumed. A discrete architecture is declared separately. Every physical reading must be derived, scoped, or left open.
What the system is and what we read off it are two different things.
no output returns to the autonomous update
A typed partial interface, ordered as matter, then geometry, then clock. Its outputs never feed back into U. declared
Its registered reading legs form a dictionary, not a completeness theorem.[D]
No total, unique or complete decoder is claimed. The specific open obligations are tracked in the Frontier.
The kernel identities are proved at their declared scope. The decoder is the work, and it is where the program can fail. Every claim on this site carries its own status.
j is the twist unit, the primitive fifth root of unity: j⁵ = 1. Four additions per step, zero multiplications, exact integer arithmetic, zero drift. Kernel reference.
Ansatz: a successful complete decoder should be forced by the declared architecture, not selected by fit. That forcing and uniqueness are not yet proved. The declared architecture contains no fitted dimensionless parameter; its one SI calibration anchor is the electron mass.
The public ledger commits, each claim with its label:
Proof, exact computation and experiment decide.
