Nit, we don't have a policy on this yet, but can you create a new file, called head_read_mimir.go and put this method there? This way we'll avoid a bunch of confclicting updates with upstream in the future.

This should go in a separate test (also as noted above, in a separate file)

In the context of cost attribution in this PR #10269, I need to retrieve the index to decrement the active series count when a series goes out of the 20-minute active series window. Since the current Index() function does not return an error, we propose introducing a new function, MustIndex(), which will never return an error. Additionally, I will add tests to ensure that both functions return the same results.
