+Subject: [PATCH] fix: avoid atan branch cut in complex trigonometric test
+
+The atan_input generator sampled (Re=0, Im=1.5) at i=N/2, which lies on
+the branch cut of complex atan at Re=0, |Im|>=1. C99 7.3.4.1 leaves the
+sign of Re(catan(+/-0 + i*y)) for |y|>1 implementation-defined: glibc
+returns +pi/2, musl returns -pi/2. xsimd matches glibc, so the test
+fails on musl-based CI (e.g. void-linux x86_64-musl) with two
+mismatches (one per complex<float>/complex<double> batch type).
+
+Shift the real start from -10 to -9.5 so Re=0 occurs at i=19000, where
+|Im|~0.975<1 - analytic territory where atan is uniquely defined and
+all libcs agree. Negative/positive real coverage is preserved; only
+the singular point on a region of unspecified behavior is dropped.
