/**
 * A directory store on a baseline root somebody commits, and the bound on the
 * render cache it paints into.
 *
 * The cache goes where `variance run` puts it, `renders` in the checkout's
 * cache, so it never lands in a tracked tree and one bound covers every runner
 * on the machine. The sweep runs once per process for each cache: a one-shot
 * `observe` opens and closes a session per call, and walking the cache that
 * often would cost more than the cache saves.
 *
 * `path` is the template each baseline is placed by, as `baselines.path` in the
 * config spells it; the store's default when absent. `projects` are the
 * config's project names, so a record a renamed project left is taken over
 * rather than refused.
