Thanks for the review @josibake, I've added the conclusions of the benchmarks to the commit message (but copied it to the PR description as well now), can you please check if https://github.com/bitcoin/bitcoin/pull/30093/commits/ebf8667f634653a2eebe404469bfb62c5bb3add2 answers your questions?

@theuni, appreciate your previous reviews and insights, please take a look at the changes I did since.

(https://github.com/bitcoin/bitcoin/pull/30263)
Most supported operating systems ship with clang-16 (or later), so bump the minimum to that and allow new code to drop workarounds for previous clang bugs.

For reference:
* https://packages.debian.org/bookworm/clang-16
* https://packages.ubuntu.com/noble/clang (clang-18)
* CentOS-like 8/9 Stream: All Clang versions from 15 to 17
* FreeBSD 12/13: All Clang versions from 15 to 16
* OpenSuse Tumbleweed ships with https://software.opensuse.org/package/clang (`clang18`); No idea about OpenSus

We do, at least to my understanding, given some `PeerMan` methods that are not called with any `CNode` reference need to check whether the peer that sent us the data they are processing is inbound or outbound.

A good example is `PeerManagerImpl::MaybeSetPeerAsAnnouncingHeaderAndIDs`, which is called from `PeerManagerImpl::BlockChecked` and is passed a `NodeId` grabbed from `mapBlockSource`

> I wonder whether a malformed call to `MakeWalletLoader` should shut down the node at all,

Thanks for reporting this. I'm confused how it happens because `MakeWalletLoader` should be called from the node process (via `Init::makeWalletLoader`method) and it should run in the wallet process. So if it crashes, it should kill the wallet process, not the node process. If you can post more details about what you found at h

Yes, but we could attempt to retrieve the `CNode` by `NodeId` from `m_nodes`, as the current code does it for `Peer` from `m_peer_map`.
I think the lookup would be `O(N)` for iterating through the vector `m_nodes` instead of `O(log N)` for the `std::map`, so maybe that is the reason for the redundancy?

(https://github.com/bitcoin/bitcoin/pull/29640#discussion_r1633646409)
Umm, I really cannot see why I wanted to do this in two steps. It really doesn't seem necessary.

I've also re-arranged the code a bit to minimize the diff

(https://github.com/bitcoin/bitcoin/pull/29640#discussion_r1633656796)
Updated to:

(should only happen with blocks loaded from disk, as those share the same nSequenceId: 0 for blocks on the best chain, 1 for all others)

📝 brunoerg opened a pull request: "test: add coverage for errors for `combinerawtransaction`"
(https://github.com/bitcoin/bitcoin/pull/30264)
This PR adds test coverage for the following errors for the `combinerawtransaction` RPC:

* Tx decode failed
* Missing transactions
* Input not found or already spent

Yeah, that'd make sense. I don't think increasing the lookup complexity for this, even if we are talking about a vector of hundreds of nodes at most, is worth not keeping a boolean in `Peer`

removed the static cast for `m_conflicting_fees` since that's the same type as `m_total_modified_fees`, but left the other static casts in place since explicit is better than implicit

> I would definitely be curious to see the other approach. Not just because it might be better at detecting inconsistent states like Luke is suggesting, but also because it seems like it would make the code more clear.

See https://github.com/mzumsande/bitcoin/commit/db8232d47068bba9ae1bb8135ef456be731e5ca5 - because of the inheritance the bool `interrupted_replay` needed to be added to quite a few spots, which I didn't love.
