Closing for now, in favour of #33911, as we might reafactor this in some way. Will follow up there.

Thanks for adjusting these.
After this PR we can remove the deprecated ones and add the new options in 17 by regenerating the config.

* Fixed conflict with #33724
* Updated coinstatsindex compatibility test to only check upgrading the version, not downgrading.

As far as I can see, that is not guaranteed in C++. `CBlockHeaderAndShortTxIDs` has a user-provided default constructor and `shorttxidk0`/`shorttxidk1` are without in-class initialization, so unless `FillShortTxIDSelector()` has run, they hold indeterminate values, not guaranteed zeros.

Either way, based on the serialization code and the constructors, the object is n

Please see the attached benchmarks in the PR description. They were part of the PR originally, but aren't really useful after this change, doesn't make sense to commit them.

I'm not really a fan of that, I explicitly try to make long and expressive commits - it can be soft-wrapped on the client-side by the vertically-challended IDEs :D

Fixes #33293

Clear out space on jobs running on GHA by deleteing unnecessary files.

Raised in #33293 which pointed to a solution like https://github.com/google/oss-fuzz/commit/b7f04d782277638a67bc44865de445977eed4708 which is adapted slightly here.

Only runs when cache provider (runner) is `gha`.

Hi AJ, are these the test vectors you had in mind?

I think you found that it doesn't work reliably. If there truly is no single way to get fuzzing to work fully reliably on macOS, it seems best to remove the docs temporarily.

📝 maflcko opened a pull request: "ci: Run GUI unit tests in cross-Windows task"
(https://github.com/bitcoin/bitcoin/pull/33919)
Most users of the cross-compiled releases for Windows will most likely pick the GUI, so running the cross-compiled GUI unit tests on a real Windows seems desirable.

Fuzzing works, I just have to disable the sanitizers, since they disable exception support - and the fuzzer halts at the very first throw.

💬 davidgumberg commented on pull request "docs: clarify RPC credentials security boundary":
(https://github.com/bitcoin/bitcoin/pull/33196#discussion_r2547793630)
I think the existing docs make it pretty clear that other processes/users with access to the machine can comprise the node, but I think what is not obvious in the existing docs is that the other direction is true as well, someone with RPC access can probably compromise the machine the `bitcoind` node is running on.
