+#
+# Emergency script: relocate stored stack paths after a DATA_DIR change.
+# Automatically detects database type (SQLite or PostgreSQL).
+#
+# When you change DATA_DIR (e.g. move the bind mount from /app/data to a host
+# path), the stack files move on disk but Dockhand's database still points at the
+# OLD absolute paths, so stacks show an empty compose. This script rewrites those
+# stored pointers from the old DATA_DIR to the new one.
+#
+# It does NOT move, copy, or delete any files - it only updates where Dockhand
+# looks in the database. A pointer is rewritten only when the old file is missing
+# AND the new file already exists on disk.
+#
+# Usage:
+#   relocate-stack-paths.sh <old-data-dir> <new-data-dir>            # dry run (default)
+#   relocate-stack-paths.sh <old-data-dir> <new-data-dir> --apply    # interactive apply
+#   relocate-stack-paths.sh <old-data-dir> <new-data-dir> --apply --all   # apply all
+#
+# Example:
+#   docker exec -it dockhand /app/scripts/emergency/relocate-stack-paths.sh \
+#     /app/data /mnt/pool/dockhand --apply
