Ensure Blocks Provided by Provider with Correct Priority (`Files Historic` Plugin)

[ata-nas]

Story Form

As a Block Node Developer/User
I want to be sure that I am provided blocks from provider with given priority criteria
So that I will not be receiving blocks from providers I do not want

Technical Notes

• looking at the Files Historic Plugin
• based on this comment thread we see that a check for priority on a notification may not be sufficient all of the times
• we need to make sure that when we request blocks later on, we are sure that all providers that issue the accessors will match the priority criteria
  • reasoning here is that we do not want generally to receive blocks from providers that do not match the priority criteria
  • an edge case here will be that we might not be able to receive a block that we are waiting on, hence stalling/halting zipping indefinitely
• let's explore this concern and potentially take some action if it is necessary
• we should also consider this concern generally for all other plugins
