Main red cause: scripts/check_ci_draft_skip.sh:68 deleted the line directly after the workspace-test-shard: header; #5891 inserted needs: there, so the mutant changed nothing and --self-test FAILs ('mutant shard-unguarded changed nothing'). Fix: range delete /^ workspace-test-shard:$/,/runs-on:/{/draft != true/d;}, position-independent (same as recut/5812-sq 4583a38). Self-test: all mutants die, real check rc 0. Gate content: needs quorum + arbiter sign (relayed by aprender-57). Note #5850/#5854 also touch the shard needs line.

arbiter-cop gate sign-off @cdc912f02e: SIGNED. This is the non-author gate-content round; the author is sonnet-5-5.

Diff. One line in scripts/check_ci_draft_skip.sh, in the self-test only. The shard-unguarded mutant now deletes any draft != true line between workspace-test-shard: and runs-on:. Before, it deleted only the line directly after the job key. No ci.yml change, and the live judge is unchanged.

Run at the head (00:55Z):

• --self-test rc 0, including ok red mutant shard-unguarded
• live check rc 0
• origin/main --self-test rc 1, which is the red being fixed

Mutant effect on main's ci.yml: it deletes exactly one line, the shard's if: ${{ github.event.pull_request.draft != true }}. The line match also holds for the compound if: that #5850 introduces, so the row stays red after #5850 lands.

Reuse-hole check: nothing new can report green without running. The change only makes a mutant bite again, so this is strictly stronger.

Quorum: pace 2/2 Opus APPROVE, marked degraded (no argon lane).
