  "risks": [
    "The libs depend on caller state: pass/fail increment PASS and FAIL, run_recon reads WORKROOT, FIXTURES and RECON. All are defined in run_tests.sh before the source lines, and the header comments say so.",
    "All three files are shfmt-dirty, but run_tests.sh was already shfmt-dirty at HEAD (2-space indent vs shfmt's tabs) and the new libs inherit that existing style. No clean file was made dirty; shfmt is not a pre-commit hook in this repo."
