RMP.11:0 - Use This When

Use this pattern when an identified Method, independently established family inclusion, or named relations among Methods are treated as natural or inevitable and a present decision depends on how that differentiation arose. Typical questions concern why a variant appeared, why one contribution separated from another, why a provider or profession retained a form, or why a relation changed under pressure.

Begin by bounding the exact Method, established family inclusion, or relation change to explain and the decision that will use the account. Decide immediately whether the receiver needs only a dated descriptive account or intends to rely on a causal conclusion.

The first useful result can be a descriptive stop: a dated sequence with source and evidence limits. When causal reliance is live, name the causal-use question, claim kind, causality-ladder rung, and required support before constructing the explanation.

Do not use a project-local grouping label as a professional-family fact. Do not use RMP.11 for decorative history, chronology, popularity ranking, or present architecture choice alone.

RMP.11:0.1 - Working Distinctions

Name used here	Meaning
explanandum	One identified Method, established family inclusion, or named Method relation and the differentiation that the present decision needs explained.
differentiation account	An episteme containing dated description, link claims, rivals, diagnostic observations, grades, limits, and reopen conditions. It does not select today’s architecture.
descriptive sequence	Dated source editions, Work evidence, variants, disappearances, and decision points with no causal-use claim.
link claim	A proposed relation among pressure or environmental change, affected actor or carrier, response or variation, selection/retention, and Method or relation change.
rival	A materially different account such as constraint, provider/tool availability, regulation, authority, diffusion/fashion, recording artifact, redesign, or survivorship bias. Rivals may coincide.
causal-use support result	A separate `C.28` result that states the question, claim kind, rung, actual support-component refs, threat screen, verdict, supported/unsupported uses, limits/window, and reopen.
non-causal observation or hypothesis	A separately named descriptive result that may justify a bounded probe without licensing a causal claim.
downstream architecture decision	A separate authorized choice that cites only support allowed by the causal verdict and keeps its own criteria, authority, stops, and burden.
