Buildable, tested, documented and installable by someone who did not write it.
See CHANGELOG.md. Nothing the paper measured has changed; what changed is that
the code can now be built with one command, tested in under a minute on any
machine, and extended through a documented backend contract.

Two runtime bugs found and fixed by the new tests: enforce mode leaked the
handler lock at connection EOF and deadlocked, and took the lock too early so
one connection starved the rest.
