The four-week pilot involved 24 volunteers. Support requests declined from 30 in week one to 18 in week four. That is 12 fewer requests; no comparison group was used, so the change does not establish causation.

Before approving an extension, review participant coverage, task mix, completion quality and the follow-up budget. Keep unresolved evidence separate from observed results.

Decision requested: authorize a limited evidence-gathering extension, with a named reviewer and a review date. This letter is a populated demonstration of the print layout, not a customer outcome or an approval record.
