Test	What it does	Result
test_azuma_width	flaw_azuma is sqrt(2n1ln(1/eps)) to 1e-14 and flaw_eps gives each of the eight bounds an eighth.	✅ pass
test_inverse_solves	flaw_inverse inverts the matrix Mizutani Eq. (101) builds from Alice's three Bloch vectors to 4e-15 across the flaw domain.	✅ pass
test_printed_entry	Mizutani Eq. (37)'s repeated third-row entry differs from the sigma_Z cofactor by more than 0.1 and misses the identity by more than 5%.	✅ pass
test_region_collapse	flaw_errors is the asymptotic estimate over the block plus each coefficient's magnitude against the Azuma width, to a part in 1e10.	✅ pass
test_region_pessimistic	The finite phase-error count never falls below the asymptotic one and the gap falls by 10 per two decades of block.	✅ pass
test_region_slots	flaw_errors refuses counts that are not six, a negative count, a degenerate pz, an empty block and an eps_ph outside (0, 1).	✅ pass
