The address, the bytecode, then a swap each way through its pool. A few seconds.

No owner() but it has claimedOf, collectFees.

3 pools over 40 days.
Measured at block 93,395,061. A hook with an owner or a dynamic fee can behave differently later; scan again before a large trade.
A v4 hook's permissions are the last fourteen bits of its address. The PoolManager calls only what they switch on.
