Regression unit test for the “shorter wins” invariant enforced by SimpleCurveExtractor ._drop_coverage_crossing_features() when both colliding features are tagged SKEL_MTH='coverage_refine'.

Fixture (synthetic, deterministic):

• Feature A: 4 points forming the horizontal segment \(y=0\) from \(x=0\) to \(x=10\), arc length ~10 m, SKEL_MTH='coverage_refine', CURVE_ID=0.

• Feature B: 4 points forming the vertical segment \(x=5\) from \(y=-10\) to \(y=10\), arc length ~20 m, SKEL_MTH='coverage_refine', CURVE_ID=0.

• The 2D segments cross at \((5, 0)\) and share a bbox-grid cell at cell_size = 5.0, so the C++ curve_segments_cross_d helper must emit the crossing pair.

• length_2d(A) = 10 < length_2d(B) = 20 STRICTLY, so the shorter-wins tie-break cannot be confused with an arbitrary ordering.

With predicate=lambda fa, fb, md: True the helper must return {0} (the index of feature A, the shorter one). If it returns {1} instead, the invariant is broken and the test fails.

EXPECTED_LEN_A_ = 10.0

EXPECTED_LEN_B_ = 20.0

STRICT_MARGIN_ = 1.0
