# Selected system

Read the current type/composition brief, chosen representative and effective tokens. Typesetter proves real/dynamic content in actual containers; Composer maps needed components and every surface/state/view. Deliver actual existing-system material, selected whole-screen references and Scout analysis to makers, not blind reviewers.

Use tokens check and, for genuine additions, schema token-extensions then tokens extend. Base tokens/aliases/text styles remain immutable; renamed equivalents are not an override loophole. New roles need actual component/state users. No speculative library or repeated direction approval for lawful additions.

Owners publish their Measurement contracts and current proof/composition bindings, then run the named checks. Changed selected content/tokens/relationship stales choice; affected downstream additions re-prove only their actual scope. Continue through stage next into full expansion, preserving debt and real blockers.
