◆ BOOST_FIXTURE_TEST_CASE() [12/16]

BOOST_FIXTURE_TEST_CASE	(	ViaBottomBackdrillLayerDetection	,
		BACKDRILL_TEST_FIXTURE	)

Regression test for GitLab #23902.

Iterating LAYER_RANGE walked PCB_LAYER_ID enum order, so a bottom-anchored backdrill (B_Cu to In3_Cu) wrongly flagged the top inner layers and skipped the actually-drilled In4_Cu. A bottom backdrill must report only the bottom-side copper as machined.

◆ BOOST_FIXTURE_TEST_CASE() [13/16]

BOOST_FIXTURE_TEST_CASE	(	ViaEffectiveShapeOnBackdrilledLayer	,

Test that the backdrill widens the hole and the physical extents on affected layers, but leaves the copper shape alone.

◆ BOOST_FIXTURE_TEST_CASE() [14/16]

BOOST_FIXTURE_TEST_CASE	(	ViaHoleShapeUsesNetclassDrill	,
		BACKDRILL_TEST_FIXTURE	)

A via can leave its drill unset and inherit the netclass value.

The hole shape must resolve that fallback, or hole-to-hole DRC measures from a zero-width hole and reports nothing.
