Corridor bundle from ('__junction_12', 1) corner 0: arc centers splay by 4.00px (>1.5); lines delaminate through the turn.
Every other fixture in this test class passes cleanly. This is a real, previously-uncaught routing defect in examples/topologies/inter_row_corridor_overflow.mmd's output - surfaced only because this fixture was moved from a validate=False-only regression file into the fully-checked topology corpus (see #1772's PR #1819, which needed a generic non-riboseq twin of the #1772 defect class and picked this pre-existing fixture for it). It predates that PR; the fixture's own layout output around this corridor bundle was never previously exercised by this particular concentric-arc-center check.
This issue is filed to record the finding and reproduction; nobody has traced the call site or the specific mechanism causing the splay yet. That's the next step for whoever picks this up - treat the numbers above as the starting point, not a full diagnosis.
