Function preflight_config 

pub(crate) fn preflight_config(
    settings: &DictateSettings,
    active: &[(DictateRole, ActiveModel)],
) -> Config

The config preflight builds the engine from: the [dictate] settings, the resolved active models, and the always-on stores under forge’s app-support dir - per-take diagnostics and the verified-digest record - machine-local and never synced.

A directory that cannot be resolved turns the capture off with a warning rather than failing preflight - diagnostics never break dictation, but the absence must not be silent either: a capability believed present and quietly missing is the failure nobody can see.
