Physics milestone module that packages a domain cost functional, a positive canonical threshold, and an inhabited MilestoneCert record. A physicist citing RS cost bounds or certification scaffolding would land here. The module is mostly definitions and elementary positivity/equality lemmas over the Cost and Constants imports, not a deep derivation.

claimDefines a domain cost $C_{\mathrm{dom}}$, the identity $C_{\mathrm{dom}}(x)=C_{\mathrm{dom}}(x)$ at equal arguments, a canonical threshold $\theta>0$, and a milestone certificate type with an explicit inhabited witness $\mathsf{cert}$.

background

Recognition Science measures mismatch with a J-cost (from the Cost import) built on the unique generator forced by the Recognition Composition Law. Constants supplies the RS-native tick $\tau_0=1$. This module sits in the Physics layer and introduces a domain-level cost functional together with a fixed positive threshold used as a pass/fail cut.

Sibling names indicate three layers: (1) domainCost and its reflexivity-style equality lemma, (2) canonicalThreshold with a positivity proof, and (3) a MilestoneCert structure inhabited by a concrete cert. No forcing-chain step (T5–T8) is re-proved here; the module assumes Cost/Constants and packages a certification interface.

proof idea

Definition-heavy module. Domain cost is introduced as a named functional; domainCost_at_eq is an elementary equality at identical arguments. Canonical threshold is a nonnegative real with a short positivity lemma. MilestoneCert is a structure (or Prop bundle) discharged by an explicit inhabitant cert and cert_inhabited. No multi-step analytic argument; proofs are definitional or one-line positivity/equality.

why it matters in Recognition Science

Supplies a reusable Physics-side certificate object tying domain cost to a canonical positive threshold. Downstream graph edges are empty in the mirror snapshot, so this module currently acts as a terminal packaging point rather than a lemma feeder. It does not itself force $\phi$, the eight-tick octave, or $D=3$; those remain upstream in the UnifiedForcingChain. Useful when a later development needs a named, inhabited milestone witness over Cost.
