`echo 'FAILED: ${c.name}'` hand-quoted a string that is prose, so the
first case name containing an apostrophe to actually fail terminated the
builder script mid-report. The remaining failures never printed, and the
error read as a shell syntax error rather than as a broken property.
Only failing cases are ever echoed, so every green run agreed the
reporter was fine -- the defect was reachable exclusively at the moment
the report was the thing being relied on. Measured: with two cases
failing, the old form printed one line and an EOF error, the escaped
form prints both plus the count.
