  "title": "Test arch_perf_report.sh, open the arch-performance family, and fix the dead journal-size check",
  "objective": "Cover the fifth of the sixteen untested fixes/lib libs and stand up the harness the arch-performance group will share. Writing the tests exposed a second dead branch -- the journal size regex demanded a space before the unit that journalctl never prints -- so this lands that fix alongside the coverage. The lib stops at 98.33%: its last line is a redirected closing brace no test can reach.",
  "acceptance_criteria": [
    "arch_perf_report.sh measures 98.33% (59/60) through lib/tests/run_all.sh, twice, with line 20 the only uncovered line both times.",
    "The old journal regex is shown NOT to match journalctl's real output before the fix, and the fixed one shown to match both the spaced and unspaced forms.",
    "Line 20 is shown to be a closing brace of a redirected group that executes, not a missing test.",
    "meta/shell-coverage-allowlist.txt is UNCHANGED -- arch_perf_report.sh does not meet the 100% bar.",
    "The four bluetooth suites and the eight pacman_hook_stall suites still pass after _t_hide and _t_full_path move into lib_test_core.sh.",
    "Every file stays under the repo's 250-line cap, and pre-commit passes with no suppression added."

  "out_of_scope": [
    "Clearing arch_perf_report.sh, bt_audio.sh or bt_adapter.sh from the allowlist. All three are capped by defect (a) in docs/kcov-under-report.md.",
    "Changing continuation_lines() in meta/scripts/lib/shell_coverage_lines.py. That is the next commit, kept separate so a denominator change can be reverted without losing these tests.",
    "The remaining eleven untested fixes/lib libs."

  "verifier": "bash linux_configuration/scripts/single_use/fixes/lib/tests/run_all.sh (expects all files passing, 17 + 21 for the two arch_perf_report files), plus bash meta/scripts/shell_coverage_jail.sh --subject linux_configuration/scripts/single_use/fixes/lib/tests/run_all.sh --measure arch_perf_report.sh --min 1 --fail-on-case-error -- \"\" (expects 59/60 = 98.33%, uncovered 20), plus bash meta/scripts/check_shell_coverage.sh on the cleared libs (expects exit 0)."
