A role model only seeded brand-new Sessions, so Workers created before a settings change kept their old route forever — the operator's complaint that the default model 'did not take effect'. On dispatch, ensure() now compares the durable selection or header of an existing Session against the configured role model and appends a model/selection event when they drift, leaving the deployment default alone. Seven unit cases cover drift, idempotence, effort, and precedence.
Ensure() only registered a Workspace when the Session was new, so Sessions restored from disk never entered the Workspace record and stayed invisible in the panel. Always create (idempotent) and attach an unaccounted Session; warn on attach failure. Tests gain a shared Workspace fixture.
