Milestone certificate module for a physics checkpoint labeled 1400. It packages a domain cost, a canonical positive threshold, and an inhabited MilestoneCert record so downstream physics can treat the checkpoint as discharged. The argument is definitional: cost and threshold are fixed from the Cost and Constants layers, then wrapped in a certificate structure.

claimThe module fixes a domain cost $C$, a canonical threshold $\theta > 0$, and a milestone certificate asserting that the domain cost meets the threshold at the 1400 checkpoint (with an inhabited certificate instance).

background

Recognition Science measures mismatch with a nonnegative cost functional (the $J$-cost family from the Cost layer). Constants supplies the RS-native time quantum and related units. This module sits in the Physics domain and does not re-derive those objects; it only names a domain-level cost and a positive cutoff used as a pass/fail gate.

Sibling definitions introduce domainCost (the cost assigned to the domain under study), an equality lemma for evaluating that cost at a point, canonicalThreshold with a positivity proof, and a MilestoneCert structure inhabited by a concrete cert. The intent is bookkeeping: mark that a named physics checkpoint has a certified cost-threshold relation rather than prove new dynamics.

proof idea

Definition-and-certificate module, not a deep proof development. Domain cost and the canonical threshold are introduced as defs; positivity of the threshold is a short lemma. MilestoneCert packages the relation, and inhabitation is witnessed by an explicit cert value. No substantial tactic proof chain beyond positivity and equality bookkeeping against Cost/Constants.

why it matters in Recognition Science

Gives the Physics tree a named, inhabitable milestone object at checkpoint 1400 so later assemblies can assume the gate rather than re-open cost bookkeeping. It does not feed any recorded downstream theorems in the current graph (used-by is empty); its role is local closure and auditability inside the physics stack. Ties to the broader RS cost layer rather than to T5–T8 forcing steps directly.
