 "result": {
  "summary": "Updates `ci/README.md` to reflect current container environments and CI harness mechanics. It replaces recommendations for an unmaintained QEMU binfmt container with modern Docker-recommended tooling, removes inaccurate claims that numbered CI scripts run sequentially, clarifies how container images and build caches are handled, and documents the policy against universally pinning CI dependencies by hash.",
  "problem": "Contributors running CI tasks locally or inspecting CI mechanics encounter outdated documentation, including unmaintained QEMU helper images, incorrect explanations of script execution order, and missing context on CI dependency pinning policies.",
  "card": "Updates ci/README.md to bring local CI setup instructions and harness documentation up to date. It replaces references to an unmaintained multiarch QEMU helper container with current upstream guidance, removes inaccurate descriptions of CI script ordering, clarifies container image and ccache behavior, and adds a section explaining the project's dependency hash pinning policy. This aids contributors attempting to understand or replicate CI environments locally.",
  "evidence": [
   "Commit fabc10bc59 notes: 'docker.io/multiarch/qemu-user-static hasn't been updated in years and the replacement according to the Docker docs is tonistiigi/binfmt.'",
   "Commit fa5edac158 notes: 'Remove note that scripts are ordered. They are not: 02_run_container.py runs before 01_base_install.sh and some scripts have no number: GetCMakeLogFiles.cmake, wrap-valgrind.py, ...'"
