Note that these numbers were calculated using GetLiquidityFromAmounts and TickToSqrtPrice and thus assume correctness of those functions.

Are you explaining being off by one compared to the Wolfram calculation?

Ah yes sorry – the expected output is bankers rounded instead of truncated due to GetLiquidityFromAmounts being bankers rounded. This does not pose any security risks as the balance is still deducted from the caller.

Does this title reflect this test case? I think the previous one might have been incorrect as well right?

Why is this removed? Is there a replacement for these test vectors?

The notion of canonical price ticks no longer exist, so these vectors no longer make sense. All the test vectors added relating to the behavior in ticks surrounding the new MinTick ensure the appropriate properties hold.
