// #region ValidationTasks.RunDetailModel [C:3] [TYPE Model] [SEMANTICS validation,run,detail,dashboard,collapsible,model]
// @ingroup ValidationTasks
// @BRIEF Screen model for validation run detail — dashboard-by-dashboard results with screenshots, issues, and task logs.
// @INVARIANT Screenshot blob URLs are cached per (dashboardId, tabIndex) key. Revoked when cache key is overwritten.
// @ACTION toggleDashboard(id) / toggleLogsSent(key) / toggleTaskLogs(key) — Collapsible section toggles.
// @ACTION loadScreenshot(path, key) — Loads screenshot blob from storage API.
// @RELATION DEPENDS_ON -> [ApiModule]
