Test	What it does	Result
test_finite_approaches_asymptotic	The rate rises with block size towards $(n/N)$ of asymptotic without reaching it: Eq. (10) of Leverrier, Grosshans & Grangier, Phys. Rev. A 81, 062343 (2010) keeps the $n/N$ prefactor, so estimation's half is never recovered.	✅ pass
test_finite_below_asymptotic	Worst-case parameters plus $\mathrm{\Delta }(n)$ hold the rate below asymptotic at every $n$, and $n={10}^9$ still yields key.	✅ pass
test_zero_key_at_small_block	At $n={10}^5$ the finite-size penalty gives exactly 0, never negative.	✅ pass
