"""Static assertions for the frontend half of Issue #6022.

The three-value worktree contract only holds if system-minted sessions
(boot-time auto-bind, onboarding) explicitly opt OUT — otherwise a config
``worktree: true`` default would leak a fresh worktree + branch on every page
load, with nothing to reap it (#6023).
