  "title": "Split update_android_hosts.sh under the 250-line cap",
  "objective": "Bring the 870-line Android hosts installer under the cap, extracting its embedded blocklist as a data file rather than leaving 247 lines of hosts entries inside a heredoc.",
  "acceptance_criteria": [
    "The entry script and all three new libs are at most 250 lines, and the extracted blocklist is data rather than shell.",
    "The blocklist the module installs is byte-identical: the md5 of the original heredoc body must equal the md5 of the extracted file.",
    "bash -n passes on the entry and every lib. The script dispatches through a `case` rather than a main(), so no seam may fall inside it.",
    "The pre-commit shellcheck hook passes on every file, with no new suppression.",
    "The entry declares SCRIPT_DIR exactly once, and it uses ${BASH_SOURCE[0]} because the libs resolve the data path through it."
  ],
  "out_of_scope": [
    "Executing the script; it pairs with a phone over adb and installs a Magisk module.",
    "Changing any blocklist entry.",
    "The other over-cap linux_configuration scripts."
  ],
  "verifier": "md5 comparison of the heredoc body against the extracted data file, bash -n on all four shell files, shellcheck -x on the entry and shellcheck on each lib, and check_file_length.sh."
