I'm usually a fan of small and focused tests that complement each other - instead of end-to-end ones that test everything. But I don't mind merging these either, done something similar in a separate follow-up PR: [`a17d820` (#33039)](https://github.com/bitcoin/bitcoin/pull/33039/commits/a17d8202c36abf8a17fb8736e05f318422a3c7fb)

I don't mind writing an `Obfuscation` object directly, it does make more sense to make that symmetric with the read.
And if you still don't like reading back what we wrote (which would exercise the same route that we'd take otherwise, seems better to me), we can also just assign it directly.

Consider unifying the way your refer to the first block that fulfills the assumevalid condition

Commit message is inconsistent with comments: `assumedvalid block` is written in your code as `assumed valid block`. I would be fine with `assumevalid block` as well, as long as they're consistent.

nit: sentence ends in `full block yet` - we could add a fullstop.

To be consistent with previous line:
```suggestion
// if the previous IBD run was interrupted before it downloaded the assumed valid block.
```

💬 maflcko commented on pull request "fuzz: add mempool_dag fuzzer for transaction dependency testing":
(https://github.com/bitcoin/bitcoin/pull/33038#discussion_r2223364583)
this is just copy-pasted from `src/test/fuzz/tx_pool.cpp`, same for the function above, with slight modifications.

it would be good to explain what exactly you are trying to test and why the existing fuzz targets are insufficient. Then, it would be good to provide coverage reports to show you have achieved your goal. Finally, it would be good to put this in the existing `src/test/fuzz/tx_pool.cpp` file, so that shared code can be re-used.

The test isn't that slow for me, but this is still a significant improvement.
