I think yall are using the terminology differently from each other in this thread. "Checksum" historically did not imply resilience against intentional modifications. Nowadays, it's arguably a best-practice when designing a new protocol or storage format to simply make all checksums cryptographically strong unless there's a reason not to. I think that might be where the confusion is coming from.
