#167

Changing view include filter triggers mass model element deletion — elements not in the new filter are deleted from the model, not just hidden from the view

Views

#166

Scoped cell ID (e.g., components—​onlineshop.db) leaks into model relationship from/to fields when element is deleted from draw.io

Reverse Sync

#169

Sync hangs indefinitely on zero-byte .bausteinsicht-sync file instead of treating it as corrupt

Sync State

#165

validate silently accepts null as a valid JSON root (should reject)

Validation

#168

add relationship rejects multiple relationships between the same element pair even when kinds differ (overly strict duplicate check)
