## Why this should be merged See ava-labs/strevm#120. To get bloom filters for a block when the header doesn't contain the correct bloom because of SAE's delayed settlement, you need a custom accessor to provide arbitrary bloom. ## How this works Introduces an optional interface which, if satisfied by `filters.Backend` implementations, is used to override the Bloom filter instead of retrieving it from the `types.Header`. ## How this was tested Existing tests unchanged. Integration test demonstrates calling of the override method when present. --------- Co-authored-by: Arran Schlosberg <me@arranschlosberg.com>
