+- snapshot schema version 7 includes group identity, distribution-board
+  components and both one-to-one protection collections
+- capture, named and automatic snapshots, restore, Undo/Redo and portable JSON
+  transfers preserve the complete new relational state
+- duplicate imports remap component UUIDs and both protection-owner references
+  together with the existing project structure
+- versions 1 through 6 remain readable; version 6 maps the three established
+  section keys to group 1 and leaves new collections empty
+- older flat circuit protection values remain present and are not guessed into
+  strict new protection configurations
+- current snapshots reject invalid ownership, duplicate group numbers,
+  cross-entity BMKs and invalid protection configurations before persistence
