 # Version Management:
 #   The VERSION file in the repo root is the single source of truth.
-#   Version bumps happen in the Dev workflow BEFORE merge to main.
-#   The deploy workflow only reads, validates, and logs the version.
-#   The [skip ci] filter remains as a safety layer for auto-triggers.
+#   Deploy only reads, validates, and logs the version.
+#   Version changes happen before merge to main, not during deploy.
