Overview

Builds the CoverageStatistics triple for a SourceFile regardless of which criteria were enabled during the run: disabled or empty criteria collapse to 0/0/0 so downstream consumers don't have to special-case enable-state.

#unaccounted?(source_file, table) ⇒ Boolean

A file tracked but never loaded once carried no branch or method tuples at all, so an empty set meant "nobody knows", and answering the empty-set default of 100% overstated it (#902). Simulation now synthesizes those tuples statically, so a file carrying a table at all, empty or not, has been accounted for: it has no branches, or a directive skipped the ones it has, and it is as covered as a loaded file with none. Only a file carrying no table for the criterion is still unaccounted for. A file with missed entries and none covered already computes to 0% either way, so only one that really has covered entries keeps its computed percentage.
