Test that the lower bounds of compat entries actually resolve and pass, using julia-actions/julia-downgrade-compat on Julia 1.10 (the minimum supported version). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Downgrade CI revealed two lower bounds that do not co-resolve with the rest of the dependency graph at their minimum versions: - BFloat16s 0.2/0.3 fail to resolve alongside the LLVM 9.10 requirement in the test environment; 0.4 is the lowest that works. - Preferences is pulled to 1.5.2 by the transitive test dependencies, so the 1.4 lower bound is unsatisfiable in the Pkg.test sandbox. Verified on Julia 1.10 by reproducing the julia-downgrade-compat transform + Pkg.test sandbox resolution. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
SparseArrays is an upgradeable stdlib whose only available version on a given Julia is the bundled one, so julia-downgrade-compat must not try to downgrade it. Keep the package version unchanged. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
