Planned changes to the TransactionHistoryIterator will require it to call into the query_lib's getExecutorFind() function. However, query_lib already has a dependency on the transaction library, so this call would create a dependency cycle.

It looks like this dependency is the result of UpdateStage::assertDocStillBelongsToNode(). Is there some way we can break that dependency so that the transaction library can safely depend on query_lib?
