  "message": "ci: an empty selection must build nothing, plus selector follow-ups (#3845)\n\nci: an empty selection must build nothing, plus selector follow-ups\n\nA PR whose build axis legitimately selected nothing rebuilt everything.\nbuild.yml reads .build.families twice - as a |-joined regex, and implicitly\nas \"is anything selected\" - but tested only -z \"$FAMILY_REGEX\", which an\nempty list and a charset-rejected one both satisfy while meaning opposite\nthings. ci_set_matrix had already returned the correct all-empty matrix;\nthe fall-open branch discarded it. #3842 and #3840 each spent 74 cmake legs\non it. Branch on the two cases instead, rename FAM_* to FAMILY_*, and cover\nthe block with a test that extracts it from build.yml and executes it - it\nhad no test at all, which is how this shipped through two merges.\n\nFollow-ups to the same machinery: glob.escape the repo root at five sites,\nso a checkout path containing [ or * stops failing closed; drop the ci-full\nlabel, read after the matrix was already computed and so never functional;\ndelete 13 mcu:MKL25ZXX / mcu:SAME5X skip tokens matching no board; carry the\nrule table in the module docstring, guarded against drift; and pin six\nselection behaviours a mutation pass proved untested.\n\nCut the selector\u0027s cost 1.8x (26.0s -\u003e 14.6s) with 0 divergences over 260\npaths, and stop scoping the membrowse upload by the PR example filter.",
