+## Move

+```bash
+tools/wikitool move --page "<Title>" --dry-run   # see where it would go first

+Moves the page's file to the directory its type-spec computes for its current frontmatter -
+`base_dir` + `layout`, the same rule `new` places a page by when it is first created. The
+destination is never chosen by hand: there is no `--to <dir>`. Only the file moves - no body, no
+frontmatter field, and the title (the wiki's only identity for a page) never changes, so no
+reference anywhere in the wiki needs updating.
+
+`--reconcile` applies the same rule corpus-wide in one call; a second run reports nothing left
+to do. `wikitool lint`'s **Misplaced Pages** finding is the advisory this fixes - it is not a
+hard error, so an unreconciled corpus is not a broken one, only one `move` would tidy.
+
+A destination that already holds a file with the page's name is refused, not silently
+overwritten - that only happens on a pre-existing duplicate-title collision, which `lint`'s
+**Duplicate Titles** finding reports separately.
