Kind: principle

Layer: Execution Core

Record: architecture:derived-party-count

Severity: contextual

Scope: allocation, coordination

Canonical: Ontology

A design rule that the number of parties a body of work implies is derived from how the work is partitioned into concerns, so two parties holding one partition reach one count.

Listed in Architecture principles, after Period-Decided Disposition and before Fan-In Ceiling.
