9. F009 cooperative preset displays pending work newest-first
10. F010 cooperative Next drains the complete LIFO batch
11. F011 manual Next advances exactly one task
12. F012 an extra manual hand-off marks a completed stack idle
13. F013 stopped preset blocks explicit Next
14. F014 releasing stop alone does not execute pending work
15. F015 Next after release drains cooperative work
16. F016 clear preserves flags, activity, and trace

npm run test:functional

The public-build parity fixture is table-driven inside one case. Each build is exercised without falsely counting the same behavior four times.
