Searchable snapshots - cold phase - not working as expected

Searchable snapshot action - in cold phase restores the index to random data tier instead of only cold data tier

This suggests you're not using data tiers, you're just setting node attributes. You should define your hot tier with node.roles: data_hot, similarly for warm and cold, then the _tier_preference filter will do the right thing.
