INTRODUCTION

English translation pending.

CORE DEFINITION

Genealogical analysis treats a concept, institution, or technique as a member of a lineage rather than as a self-contained object. It maps ancestor concepts, sibling variants, cross-borrowings, and the turning points where the lineage changed direction. The purpose is not antiquarian: knowing what a practice inherited from a military theory, or a doctrine from an older one, reveals which of its features are load-bearing and which are accidents of history, which often changes what you should keep and what you should drop.

SCAFFOLDING EFFECT

Reduce cognitive load

- Draw the ancestors: for any practice you rely on, list the older ideas it descends from. - Mark the borrowings: note what came in from other fields, and what was lost in translation. - Find the turn: locate the moment the lineage changed, since that is where its current form was set.

Anchor fast decisions

Any current practice is a snapshot of an accumulated history, and its features carry the record of the problems it was built to solve, some of which no longer exist. Tracing the lineage makes that record readable: inherited constraints become visible as constraints, and accidental features become recognizable as accidents. This is why a genealogy supports better pruning than a feature list does, because it tells you which parts are doing structural work and which are merely inherited furniture.
