  "message": "ci_select: classify the 254 files that were reaching rule 17\n\nRule 17 (unclassified -\u003e full on both axes) is the fail-open net for paths nobody\nanticipated, and it must stay that way: a wrong `full` costs runner minutes and is\nvisible in the run, a wrong `empty` costs a merged regression and is invisible.\nBut nothing in the tree should REACH it, and 254 tracked files did.\n\nThe cost was real. PR #3842 changed a skill, a README and .gitignore; .gitignore\nmatched no rule, so both axes went full and 74 cmake legs span up runners to do\ncheckout + toolchain + get_deps before skipping the build, plus the whole 30-board\nrig. Three changes, none of which touch rule 17 itself:\n\n1. _META_RE - repo metadata and tooling no Build step reads: .gitignore,\n   .gitattributes, .clang-format, .codespellrc, .pre-commit-config.yaml,\n   .readthedocs.yaml, .PVS-Studio/, .idea/, sonar-project.properties, the\n   packaging manifests, CMakePresets, udev rules, test/{fuzz,unit-test} (their own\n   jobs build those), the non-build .github/ files, and the tools/*.py scripts no\n   build invokes. Deliberately NOT included, and still full: .circleci/**,\n   .github/workflows/build*.yml, .github/actions/**, .github/scripts/**. The line\n   is \"does a Build step read this\", not \"is it source\".\n\n2. Rules 15 and 16 now match what they already claimed. Row 15 names\n   examples/\u003crole\u003e/CMakeLists.txt and the regex never had it; row 16 says\n   tools/build*.py but anchored tools/build\\.py$. Both got the right answer only\n   because rule 17 caught them on the way past. Also names their siblings -\n   family_support.mk, family_rules.mk, src/CMakeLists.txt, src/tinyusb.mk - and\n   .circleci/**, which generates the whole CircleCI matrix and was in no row at all.\n\n3. src/typec/** gets row 12b. It is listed unconditionally by both build systems\n   but its body is `#if CFG_TUC_ENABLED`, which only examples/typec/power_delivery\n   sets - the same shape as the class rule, so the same answer: the examples that\n   enable it (stm32g4 and stm32u5 after the buildability prune), and nothing on the\n   rig, which runs no typec test. It was force-fulling 82 families and all 30 boards.\n\nTestNoTrackedFileIsUnclassified walks every tracked file and asserts none reaches\nrule 17, on both axes - 254 -\u003e 0. Verified it fails when a new unclassified path\nappears. That turns 17 into what it should be: unreachable for anything in the\ntree, so it fires only for genuinely new shapes, and the author is told to write\nthe row rather than letting the fall-through pick an answer for them.\n\ntest_full_paths used sonar-project.properties as its stand-in for \"unclassified\";\nthat is now metadata, so the case moved to the new\ntest_repo_metadata_is_not_a_build_input, with test_the_build_machinery_is_still_full\npinning the other side of the line.\n",
