Since further work continued in the chamber last week, the final chamber closeout had not been completed.  After checking for task completions for the final, final time, I went in and

1) checked for tools (none found, good)

2) removed the in-chamber stool

3) took a few more pix

4) re-inspected the naked BS optic (yep, dirty @ ~1-3 particles per square inch in many regions of both HR and AR face - some there prior to last week)

5) wiped my way out of chamber

6) placed verticle 1" witness optic under the BS suspension.
