  "objective": "Move monitor.sh's eleven _check_* probes into two sibling libraries so every resulting file is under 250 lines, with monitoring behaviour byte-identical.",
  "acceptance_criteria": [
    "test_monitor.sh reports exactly 9 passed, 0 failed — the same count as before the split",
    "verify_shell_split.sh reports all 25 top-level functions moved verbatim",
    "run_phone.sh --help exits 0, proving the source chain resolves in the real consumer",
    "shellcheck is clean on each of the three files checked standing alone, with no suppressions",
    "check_file_length.sh --all drops from 24 over-cap files to 23, with no new file over the cap"
  ],
  "out_of_scope": [
    "deploy.sh copy lists: lib/monitor.sh is PC-side and deploy.sh never references lib/",
    "Any behavioural change to the probes themselves",
