Regional conversion to Mw: unknown type handling · case 04

Md and lower-case ml values are published as Mw unchanged.

Case contract

Case-sensitive type. ML: < 3.5 -> 0.8 ML + 0.6; 3.5..6.0 -> ML; > 6.0 None. mb: 3.5..6.2 -> 1.54 mb - 2.54, else None. Ms: <= 6.1 -> 0.67 Ms + 2.07; 6.1 < Ms <= 8.2 -> 0.99 Ms + 0.08; else None. Other types None. Round half up to 0.1 via floor(x*10 + 0.5)/10.

Why this case matters

Homogenised catalogues convert heterogeneous magnitudes to a common Mw.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
