Why: the nine submodule entry docs and the documents migration record merged
via their own PRs; the parent must pin the new combination and register the
adoption with honest enforcement levels.
Evidence: per-repo PR merges (9x entry-docs PR#1, documents PR#2) verified
via API; make test on this branch follows before merge.
Impact: gitlinks advance to post-migration, gate-adopted mains; policy/
adoption.md registers enforced (local hooks) vs advisory vs manual honestly.
