MCIR Domain Standards Program (MDSP)

The MCIR Domain Standards Program proposes a shared constitutional substrate through which independently governed domains can publish canonical artifacts, explicit law packs, execution bindings, receipts, conformance tests, amendments, and forks. Its objective is not uniform policy. It is mechanically inspectable divergence: implementations should be able to determine whether artifacts are byte-identical under the same regime, which standard profiles they implement, how they differ, and whether a declared compatibility claim survives testing. The program must be federated rather than semantically universal. Canonicalization can provide one deterministic representation within a declared grammar and equivalence regime; it cannot provide universal semantic uniqueness across law, institutions, networks, finance, medicine, or physical systems. Hash equality establishes equality of canonical bytes in a versioned domain. Semantic equivalence, behavioral correspondence, legitimacy, safety, and legal effect remain separate claims. Each domain begins with the source triad: MCIR domain law, an execution binding, and a conformance suite. This paper expands the triad into a governed standards envelope containing provenance, authority, amendment procedure, compatibility declarations, security and safety scope, evidence, lifecycle status, and withdrawal or fork semantics. It also distinguishes syntactic, semantic, behavioral, governance, and safety conformance. Program sequencing should follow dependency and risk, not only architectural ambition. Closed, reversible, low-harm profiles should establish the core before safety-critical, financial, clinical, or actuation domains are attempted with independent experts and authorities. The paper remains a roadmap. It establishes no standard, standards body, domain authority, implementation, or conformance result.
