A Selection-Rule Calculus for Finite Record Physics: static predicates, monitored recovery instruments, and physics-bearing environment records
David Elliman
Abstract
STATUS (18 October 2026). The physics programme that motivated this work was concluded in October 2026 and its claim of a unified derivation withdrawn. The results in this paper do not depend on that programme and stand as stated. Its Koide inventory holds as a count, not as a physical phase [G97]. Selection rules are usually treated as allowed/forbidden labels. In a finite record-bearing substrate that is not enough: a static predicate can define a codespace, but it writes no environment record, carries no phase, produces no entropy, and cannot generate a measurable response. A selection rule becomes physics-bearing only when implemented as a monitored recovery instrument with syndrome bits, a recovery map, and a Stinespring environment. This paper formulates the resulting selection-rule calculus. The central theorem is a register-access rule: a monitored constraint can generate records only in the registers its syndrome and recovery actually read — so a colour rule cannot supply a generation phase, a sterile repair cannot generate a generation covariance, and a chirality lock cannot repair a colour-counting deficit. The worked example is the Dynamic-R1 mechanism: the forbidden fourth-generation corner G0G1=11 as an active recovery boundary; Hasse-edge environment records giving the covariance block KR1=BBT; the closed oriented cochain as the Majorana/CP sign carrier; and the CP-even Koide contact inventory (e,ν,d,u)=(2,3,3,2)/(9,9,27,27). The same calculus explicitly forbids using this closure to rescue the baryogenesis magnitude η=(3/14)α04: the numerator 3 remains an ideal-code count, not a physical B−L source count. The contribution is both constructive and disciplinary: monitored selection rules can become new physics, but only in the registers they actually monitor. All claims are backed by executable gates in the programme repository.
