From f12ef15469115f51fc70fe07c3ceb4797169417b Mon Sep 17 00:00:00 2001 From: ChrisRackauckas-Claude Date: Fri, 9 Jan 2026 12:07:49 -0500 Subject: [PATCH 1/3] Mark hvcat block matrix tests as broken on Julia 1.13+ On Julia 1.13.0-alpha2, the `[a b; c d]` block matrix syntax for ComponentArrays does not dispatch to ComponentArrays.hvcat method but instead falls back to LinearAlgebra's method. This causes the axes to be lost and the result to be a plain Matrix. This marks the affected tests as @test_broken on Julia 1.13+ until the dispatch issue can be investigated further.
