Giving us 2x mainnet should give the fuzzers enough time to break things before we reach that level. See 11a2d3a63e90cdc1920ede3c67d52a9c72860e6b for an example of how gradually these values change for 1 release.

Agree here, it seems to be a more taxing test to not pretend like there are any more headers, that `HeadersSyncState` will have to make do. Will consider changing this if I push, although it is the same on master. Maybe making it random or doing a `for x in {true, false}` loop over it would be even better.

I think the idea is to pretend that our peer has longer chain, meaning they are able to send us more headers, it's just that `HeadersSyncState` should be detecting that we've met the threshold and switch to `REDOWNLOAD` even though we tempt it that there are more headers in case it erroneously wants to continue `PRESYNC`.

@theuni Thanks for stating your preference. If I am following, you would like to:
1. Link cap'n proto and libmultiprocess into `bitcoind` and expose a new `-ipcbind` option there instead of only exposing it through the new `bitcoin` binary.

@yancyribbens [pointed out](https://github.com/p2pderivatives/rust-bitcoin-coin-selection/pull/108#issuecomment-3202107069) that SRD would fail to find a possible solution if there are multiple UTXOs of the same effective value with diverse weight.
This adds a tiebreaker that will make SRD succeed in such a scenario.

The root issue here appears to be that `ChainstateLoadResult CompleteChainstateInitialization` calls `LoadGenesisBlock` before the chainstate is detected as corrupt, which then clobbers blk00000.dat via `AllocateFileRange` as it (re-)writes the unindexed genesis block to disk.

Yes, I don't think the `bitcoin` binary as such is an issue. If we end up going for a "`-ipcbind` in `bitcoind`" approach, and we'd have chosen that earlier, that would have removed some of the impetus for adding the `bitcoin` binary - but it seems independently useful to have something that wraps even just `bitcoind` and `bitcoin-cli`.
> your and sipa's approach would bake IPC features ... into all binaries when their only practical use is for the mining interface.

Thanks again for clarifying sipa. I believe adding the `-ipcbind` to `bitcoind` and having separate build flags for IPC and multiprocess features is a reasonable approach and something I want to propose and discuss further in #30983.

We shouldn't expect the average Bitcoin Core contributor to consume 90min CMake videos but it's great that you do.
He also suggests every tool should support compile_commands.json and any issue/suggestion to do so would be massively upvoted.
(Adjacent issue: I never build within my IDE, so even if it were to set the environment variable automatically, I would not have benefited from that).
