C3D-0408 · READ-ONLY: state of the 7 target layers after the failed C3D-0407 [C3D-KILLCHK] done

After C3D-0407 aborted with eInvalidLayer, reports for each of the 7 target layers whether it still exists and how many top-level/guts entities remain, plus the current layer, to see what the failed run actually did.

// Read the state of the 7 target layers after the failed C3D-0407: do they still exist, and
// how much is on each. Determines what actually happened before the eInvalidLayer abort.
