+      # cache-manager's createCache, and cache-manager 7.2.9 (the latest) still
+      # depends on keyv ^5.6. Bumped alone to 6.1.0, keyv broke every redis
+      # purge (#234): it has no `opts` at all, so the provider's
+      # `cache.stores[0].opts.store` threw "Cannot read properties of undefined
+      # (reading 'store')".
+      #
+      # Fixing that accessor is not the port. keyv 6 wraps @keyv/redis 3 in a
+      # bridge adapter and no longer defaults the "keyv" namespace, so the
+      # SMEMBERS enumeration (#131) and cluster-safe delete (#100) would be
+      # skipped and purges would quietly match `undefined:*` instead of
+      # failing. Port it deliberately once cache-manager supports keyv 6.
+      #
+      # This does not hold up the move to node-redis: @keyv/redis 4 and 5
+      # already use @redis/client and still peer on keyv ^5, so that migration
+      # (#239, with the plugin-redis v3 rewrite) can land on keyv 5. Only
+      # @keyv/redis 6 needs keyv 6.
