E.20:4.1 - Step 1: Classify the introduction
A MIP-run SHALL first classify the change, because different classes have different governing definitions:
- New declared operation family or archetypal grounding. The
EntityOfConcernRefnames an operation family not previously declared at the selected governing locus. - New mechanism declaration or semantic edition. One A.6.1
U.Mechanismepisteme receives new identity-bearing content or a new effectiveU.ReferenceScheme. - Neighboring mechanism-relation change. A realization, refinement, conservative extension, equivalence, bridge, evaluation, evidence-use, or publication relation changes while the mechanism content does not.
- Suite change (membership, obligations, spec pins, or suite protocols).
- Planned-baseline change (new or revised declaration-local planned-filling rows inside one exact
U.WorkPlan, or changes to their pins). - Wiring change (new or revised Part-G extension modules, SoTA method packs, or selectors).
- Terminology migration (renames, token splits or merges, or register changes).
- Deprecation, supersession, or retirement (status change, successor relation, and preserved citeability; apply E.20:4.9.1).
Mechanism-kind boundary. MechanismDefinitionRef is a designator. Minting it neither creates a U.Mechanism episteme nor admits a new U-kind. A new U-kind claim requires E.24.UK; a new mechanism episteme must satisfy A.6.1 identity and content; a new transformation-flow structure requires E.18.
A.6.1 compatibility. Mechanism identity is <content, EntityOfConcernRef, effectiveReferenceScheme>. Identity-bearing content comprises direct subject and range fields, OperationAlgebra, LawSet, AdmissibilityConditions, Applicability, and an optional SignatureManifest when dependency replay matters. An operation index may be derived from the declaration-local operationDesignator values; it is not another content group. Each operation’s arguments and results remain A.6.1 ArgumentDeclaration and ResultDeclaration content. A.6.5 SlotSpecs remain exclusive to a RelationSignature for an already governed direct relation. Realization, refinement, extension, bridge, evaluation, evidence-use, and publication relations are governed separately.
New-declaration criterion. Treat a change as a new declared operation family when EntityOfConcernRef changes. Treat changed mechanism content or effective reference scheme as a new semantic edition. A changed neighboring relation alone does not create a new mechanism identity, although it may reopen reliance on the current declaration.
A single MIP-run MAY span multiple classes, but SHALL treat each class with its correct governing-definition assignment (below).
