Why: Keep the completed settings flows readable without adding unused API exports or duplicate helpers.
Evidence: SELF /tmp/project-settings-simplify-green-20261014-973d52c1.json records settings tests/vet, 284 Frontend tests, typecheck, the unchanged knip baseline and diff checks. Reuse and quality passes were independent read-only agents; efficiency was reviewed inline after the host rejected another review thread.
Impact: Preserve scope rules, write guards, DTOs, errors and ordering. Reuse Core ownership constants and path lookup; remove unused exports and keep permission selection in a typed local state.
