+"""n8n — upgrade stage (D2): deploy the previous published version, write a data marker into the
+persistent /home/node/.n8n volume, upgrade to current/$REF, assert health + data survival.
+
+n8n state lives in the .n8n volume (sqlite + config); the marker is a file there, read back via
+`exec_in_app` (not HTTP-served)."""
