+- Generate compatible UUIDs on browsers and Unraid WebViews that do not provide `crypto.randomUUID()`.
+- Prefer cryptographic random bytes when available and retain a schema-compatible last-resort fallback.
+
 ### 2026.06.15.r014
 - Add a dedicated workflow for attaching and immediately testing an existing Restic repository without initialization.
 - Detect a missing Restic config at local and mounted paths and suggest direct child directories that contain a repository.
