Shortfall.
One pass of the beat that fills the shortfall: every wanted cell read, a deepening asked for each entity its predicate names on the cell's source, the cell planned, covered once every deepening is fetched, or not satisfiable with the reason when the source needs a held identity the tenant does not hold
