From 40caf8cd8a175e23ed5fe7ebe017955b9026ccab Mon Sep 17 00:00:00 2001 From: ChrisRackauckas-Claude Date: Sun, 5 Jul 2026 07:28:36 -0400 Subject: [PATCH] Add centralized Downgrade CI lane (Core group, FEniCS container) FEniCS.jl is a PyCall wrapper around the Python FEniCS/DOLFIN FEM stack; its Core tests only load and run inside the cmhyett/julia-fenics:latest container (which the existing CI already uses). It nonetheless has real registry Julia dependencies with compat floors (PyCall, SpecialFunctions, ADTypes, OrdinaryDiffEq, OrdinaryDiffEqSDIRK, SciMLTesting), so a downgrade lane is meaningful. Route it through the centralized reusable workflow with the same container so the floors are actually build+tested against the Python runtime. Validated locally inside the container at Julia 1.10 (lts) with julia-downgrade-compat v2.6.1 floors: resolve + buildpkg + GROUP=Core test all green (Core 35/35 pass).
