- * An active coverage report owns the coverage driver, so TIA cannot open a
- * session of its own and has to piggyback on PHPUnit's — which is scoped to
- * `phpunit.xml`'s <source>, not to the whole project. Edges recorded that way
- * are missing every source file outside that scope, and a change to one of them
- * would select nothing and replay a pass. Invariant 3 at its most dangerous.
- *
- * The rows below assert what a coverage run may and may not leave behind. They
- * are deliberately silent about exit codes and result counts: `--coverage`
- * itself fails on an interpreter with no driver, so only the graph's fate is
- * the same everywhere.
