Version 1.4.2+dfsg-1 of r-cran-hardhat is marked for autoremoval from testing on Sun 31 May 2026. It depends (transitively) on r-cran-sparsevctrs, affected by #1134225. You should try to prevent the removal by fixing these RC bugs.
Migration status for r-cran-hardhat (1.4.2+dfsg-1 to 1.4.3+dfsg-1): Waiting for test results or another package, or too young (no action required now - check later)
