  "summary": "Backports Guix build configuration updates from master to the 32.x maintenance branch. It bumps the Guix time-machine commit, skips tests that fail during native builds on riscv64, explicitly declares python-setuptools, and updates certvalidator for Python 3.12 compatibility.",
  "problem": "Deterministic release binaries cannot be built natively on RISC-V hardware on the 32.x branch due to package test failures and Guix time-machine limitations. In addition, updating to Python 3.12 broke Guix builds requiring setuptools and the test loader in certvalidator.",
  "card": "Backports Guix build configuration fixes from master to the 32.x maintenance branch to re-enable building release binaries on RISC-V hardware. It updates the Guix time-machine commit, skips failing tests for packages on riscv64, and addresses Python 3.12 incompatibilities with setuptools and certvalidator. This backports upstream fixes from PR #36233 and PR #36425, resolving issue #36232 for the 32.x release cycle.",

   "Commit a5e6a09956 notes it 'is necessary to unblock building on RISC-V systems' and fixes issue #36232.",
