- Line 37: Update the tests using use_fake_drand_quicknet so they pass
DrandConfig directly where possible; otherwise, synchronize all relevant
FOREST_DRAND_QUICKNET_CONFIG reads and writes and DRAND_QUICKNET initialization
with one shared test lock, rather than locking only calls to
use_fake_drand_quicknet.

In this case you should comment it - which entry is needed by which test. Right now it seems like a bunch of unrelated beacon entries.
Unfortunately this makes RPC snapshots brittle and against the way they were supposed to work. RPC snapshots are supposed to be self-contained, with DB entries, index and so on. It seems you are introducing something that makes them highly coupled with some random util in src/beacon/tests/fake_drand_server.rs; now if I generate a new RPC snapshot that requires a specific beacon entry, it will fail miserably with some cryptic message (most likely). Then I would have to figure it out and hardcode it here. Afterwards, if the snapshot gets removed or changed, it's likely the entries here will become stale.
The way I see it,struct RpcTestSnapshot would have to be enriched by (optional) beacon entries. Let me know if it's unclear.
