> {\{BucketProtoUtils.toPB(BlockCacheKey)}} does not serialize the \{{archived}} flag, although the recovery path reads it. The missing field defaults to \{{false}}.
> After a RegionServer restart, archived blocks restored from the persistent BucketCache are incorrectly counted toward their original region's cached size.
