Reduce the number of competing definitions for one concept
Measure: competing definitions per concept
A concept is owned by exactly one place and referenced everywhere else. Models, skills and corpora federate by reference rather than by copy, so a definition has a single home and every consumer reads the same one.
Each outcome names the measure it moves and the direction it moves it — the value is stated as a measure, not as a claim.

Once a definition is pasted into a second document it starts aging on its own schedule, and the two versions are indistinguishable until something breaks. Federation replaces the copy with an edge: the owner keeps the definition, and everyone else resolves it.
Each concept owns one skill directory holding its definition, its curated corpus and its evaluation. Membership is federated by link rather than duplication, so a fact line in a model resolves to the owning concept's directory. Raw authoritative sources stay separated from curated truth, so what a standard says and what ageni concluded from it never merge by accident.
