Renum Wiki 
==========

Rename any markdown filename in ``wiki/`` that starts with a
**1-digit number** followed by an underscore by **prefixing a 0**
to the number.

**Examples:**

- ``7_alembic.md`` → ``07_alembic.md``
- ``9_conn_pass.md`` → ``09_conn_pass.md``

**Keep unchanged:**

- ``11_scheduler.md`` → ``11_scheduler.md``
- ``10_celery.md`` → ``10_celery.md``
