+## 🔵 [admin-subtree-import-and-cleanup] — Шаги 3-7 миграции: импорт 4 split-веток из MoreThenCms в admin (clean prefixes через `git subtree add`, populated prefixes через `git read-tree --prefix` merge), cleanup CMS-следов из mixed splits, STATUS.md merge, index.md regen, push на Gitea.
+
+Объединено в одну таску потому что: тот же agent, та же session, sequential steps без natural review-point между ними. См. `.wiki/concepts/admin-infra-project.md` §Migration mechanics шаги 3-7.
+
+**Status:** blocked
+**Where I stopped:** (not started)
+**Next action:** **3a. Clean prefixes:**
+```powershell
+cd ~/projects/.admin
+git remote add morecms ~/projects/MoreThenCms
+git fetch morecms
+git rm .wiki/entities/.gitkeep .wiki/sources/.gitkeep
+git commit -m "prep: clear gitkeep before subtree import"
+git subtree add --prefix=.wiki/entities morecms/split-wiki-entities
+git subtree add --prefix=.wiki/sources  morecms/split-wiki-sources
+```
+
+**3b. Mixed prefixes (`.wiki/concepts/` and `.tasks/` already have content):**
+
+Preferred — `git read-tree` merge:
+```powershell
+git rm .wiki/concepts/.gitkeep
+git commit -m "prep: clear concepts gitkeep before import"
+git fetch morecms split-wiki-concepts
+git read-tree --prefix=.wiki/concepts/ -u morecms/split-wiki-concepts
+git commit -m "import: .wiki/concepts/ from MoreThenCms via subtree-split (history preserved via read-tree)"
+
+git fetch morecms split-tasks
+git read-tree --prefix=.tasks-imported/ -u morecms/split-tasks
+git commit -m "import: .tasks/ from MoreThenCms via subtree-split (staged at .tasks-imported/)"
+# Затем merge content with admin's existing STATUS.md (см. шаг 5).
+```
+
+Альтернатива при конфликтах — temp-prefix dance (`.tmp-concepts/`, `git mv`, `git rm -r .tmp-concepts`).
+
+**4. Cleanup CMS-следов:**
+```powershell
+git rm .wiki/concepts/cms-admin-assets-root-folder-seed.md `
+       .wiki/concepts/cms-config-rewrite-pattern.md `
+       .wiki/concepts/cms-maljarka-https-mode-crash.md `
+       .wiki/concepts/cms-server-port-leak-fix.md `
+       .wiki/concepts/webconfig-password-xml-escape.md `
+       .tasks-imported/cms-admin-assets-root-folders-seed.md `
+       .tasks-imported/cms-admin-assets-root-folders-seed.inserted-rows.txt `
+       .tasks-imported/cms-maljarka-https-mode-bug-fix.md `
+       .tasks-imported/cms-port-leak-fix.md `
+       .tasks-imported/traefik-maljarka-502-bug.md
+git commit -m "cleanup: drop CMS files imported via subtree (they stay in MoreThenCms)"
+```
+
+**5. STATUS.md merge:** скопировать non-CMS таски из `.tasks-imported/STATUS.md` в admin/.tasks/STATUS.md (сохраняя 🟢 done статусы); удалить `.tasks-imported/`; rename per-task files в `.tasks/`. Commit `tasks: merge imported MoreThenCms task history with admin live agenda`.
+
+**6. index.md regen:** обновить `.wiki/index.md` чтобы catalog отражал импортированные entities/concepts/sources. Commit `wiki(index): refresh catalog after subtree import`.
+
+**7. Push:** `git push origin master`.
+
+Acceptance:
+- `git log --follow .wiki/concepts/wd40efax-smr-cascade.md` показывает MoreThenCms-era коммиты (history preserved)
+- `ls .wiki/entities/` содержит все 6 файлов
+- `ls .wiki/concepts/` содержит 18 admin-domain + admin-infra-project (новый)
+- `cat .tasks/STATUS.md` содержит и live agenda (pointers + impl + secrets + roadmap), и imported 🟢 done items
+- Gitea web shows updated tree
+
+Done — 🟢; unblock `morecms-cleanup-and-breadcrumb` + `resilience-roadmap-design`.
+**Blocker:** admin-infra-project-pointers, morecms-subtree-split
+**Branch:** n/a
