Honor the timetravel contract
apy() reads Date.now(), so historical backfills still use the live 24h window. Thread the requested timestamp through this adaptor (and align the price lookups to the same time), or set timetravel: false.

accept and use the requested timetravel timestamp instead of calling Date.now(),
and derive both block lookups from that same timestamp so historical backfills
calculate the correct 24-hour window. If this adaptor cannot support a supplied

Do not report a missing price as zero TVL.

A missing price becomes 0, which passes keepFinite; a price-service failure therefore emits a false zero-TVL pool. Skip the pool unless its price is finite and positive.

Suggested guard 
-    const price = pricesByAddress[vault.underlying.toLowerCase()] || 0;
+    const price = Number(pricesByAddress[vault.underlying.toLowerCase()]);
+    if (!Number.isFinite(price) || price <= 0) return null;
...
-  return pools.filter(utils.keepFinite);
+  return pools.filter(Boolean).filter(utils.keepFinite);

Also applies to: 86-86

handling in the vault TVL calculation to stop defaulting missing prices to zero.
Before calculating tvlUsd, validate the resolved price is finite and greater
than zero, and skip the current pool when it is not; apply the same guard to the
corresponding price lookup at the other reported occurrence.
