+# nh3-dev: /srv/nemi/books, the book drop Nemi validates into ~/library/<shelf>/ (albok unit 8; albok-dev 2026-10-16 after
+# Prime: "build the books drop folder in nemi ... a rejection folder feels appropriate"). Same shape as /srv/nemi/inbox
+# (playbooks/nh3-dev-nemi-inbox.yaml, which created group nemi-drop and /srv/nemi): Nemi moves each valid epub from
+# fiction/ or nonfiction/ into ~/library/<shelf>/, and anything it refuses into rejected/ beside a reason file.
+#   scripts/elway infra-ops@10.100.10.50 --playbook playbooks/nh3-dev-nemi-books.yaml
+# Writers: group nemi-drop (lkraven, infra-ops). Nemi runs as lkraven from the user manager, whose groups predate
+# nemi-drop, so lkraven gets in through the u:lkraven ACL entries, NOT the group (see servers/nh3-dev/README.md).
+steps:
+  - name: Prerequisites from the inbox playbook (group nemi-drop, /srv/nemi with u:lkraven:rx)
+    shell: |
+      getent group nemi-drop >/dev/null && test -d /srv/nemi && getfacl -p /srv/nemi | grep -q '^user:lkraven:r-x'
+    changed_when: "false"
+  - name: /srv/nemi/books and fiction/ nonfiction/ rejected/ (lkraven:nemi-drop 2770, same ACL as the inbox)
+    sudo: true
+    shell: |
+      for d in /srv/nemi/books /srv/nemi/books/fiction /srv/nemi/books/nonfiction /srv/nemi/books/rejected; do
+        install -d -o lkraven -g nemi-drop -m 2770 "$d"
+        setfacl -m u:lkraven:rwx,g:nemi-drop:rwx "$d"
+        setfacl -d -m u::rwX,u:lkraven:rwX,g::rwX,g:nemi-drop:rwX,o::--- "$d"
+      done
+      getfacl -p /srv/nemi/books
+    creates: /srv/nemi/books/rejected
+verify:
+  - name: Nemi's own context (lkraven's systemd user manager, groups fixed at boot) can list every books dir
+    shell: runuser -u lkraven -- env XDG_RUNTIME_DIR=/run/user/1000 systemd-run --user --wait --pipe -q ls -ld /srv/nemi/books /srv/nemi/books/fiction /srv/nemi/books/nonfiction /srv/nemi/books/rejected
