  "title": "Split setup_nextcloud_raspberry.sh under the cap, deferring check_and_enable_services.sh",
  "objective": "Bring the largest linux_configuration script (1383 lines) under the 250-line cap, and confirm that a script built around one shared accumulator array cannot be split without a suppression.",
  "acceptance_criteria": [
    "The entry script and all eight new libs are at most 250 lines.",
    "The pre-commit shellcheck hook passes on every touched file, with no new suppression and no disable directive.",
    "No lib sources a sibling: the entry script sources all eight directly.",
    "The stubbed run reports every moved function as defined.",
    "Every unguarded cd exposed by the split is fixed rather than suppressed.",
    "No script is executed. This one flashes SD cards, installs packages over SSH and configures MariaDB, PHP and Apache.",
    "check_and_enable_services.sh is fully restored to 1337 lines, with the unrelated lib already in that directory left in place."
  ],
  "out_of_scope": [
    "Executing any flash, install or configure step.",
    "check_and_enable_services.sh, whose SERVICE_STATUS associative array is declared in one prospective lib and written by every other.",
    "Changing what any script does when run, beyond the cd guards."
  ],
  "verifier": "meta/scripts/verify_shell_split.sh, plus pre-commit run --files over all touched files, plus check_file_length.sh, plus ls of the shared lib/ directory after the revert."
