Fiche #5 - Smoke Test E2E Minimal (dry-run)

Auteur: Dom, Alice Kiro - 15 décembre 2024
Objectif: Test ultra simple qui valide le chemin critique sans cliquer pour de vrai

Valide: ScreenState + UIElements → TargetResolver → ActionExecutor (dry-run)
=> Barrière anti-régression : si ça passe, tu as le droit de respirer !
