A.2.8.PER:3 - Forces

Force	Tension
Latitude vs duty	Permission makes an action allowable; it does not require the action.
Weak evidence vs world relation	A complete-frame search can support non-prohibition, while an incomplete search is unresolved.
Enduring grant vs instituting act	A speech act can ground a permission without being the continuing relation.
Beneficiary variety vs kind discipline	System-role kinds, exact assignment occurrences, and parties all occur in practice, but one generic beneficiary U-kind would erase their different eligibility tests.
Current grant vs actual exercise	A grant may obtain without work; work may occur without matching or exercising the grant.
Local policy vs visible artifacts	A permit or gate display is easy to see, but scope, window, currentness, revocation, and precedence decide use.
