Any reason to change the sequence id? I think this isn't changed in `loadtxoutset` either?

```suggestion
index->nChainTx = 0;
```

isn't this always true? Maybe you meant to type `-` instead of `<`?

In any case, the test seems to be passing either way, so this is "dead" code, similar to a code comment.

Can this be further limited to only mark the snap_block if it has ASSUMED_VALID set? Otherwise, nodes which never used loadtxoutset will assume that some block is a "snapshot block", even though they never used that feature.

Is removing the validity check intended?

To summarize the "network topology aware" scenario, what happens with Alice and Bob's channel is:
1. Bob broadcasts his commitment transaction + cpfp from his anchor
2. This transaction propagates to everyone except Alice, somehow. [1]
3. Alice broadcasts her commitment

Thanks Luke, I agree that repeated string concatenation was not a particularly neat for creating a single string where we could simply modify in place. I've updated this further from your version to use a lambda in bf9b11d8f6c0af9b2c76674481e5905a00240cf5.

Re Windows. Yes, fs::permissions is "supported", but IIUC without devolving into access control lists, it all boils down to whether the write bit is enabled. I don't see the sense in supporting either of these things here personally. The de

I've created https://github.com/bitcoin/bitcoin/issues/26972 to track ideas on how to detect those silent build issues, or at least make them easier to spot.

> The note about changing the type in 2024 was also removed. This passes all extended tests.

I don't think you need to detail what is changed and if the tests pass in the description. It would be better to focus on information that is useful to reviewers. For example, a measurement of memory before and after.

Also, when changing the type, you'll have to check all places where this is used, and update them, if needed. For example, casts should be removed and other types need to be increased

(https://github.com/bitcoin/bitcoin/pull/29189#issuecomment-1926968881)
> This library has existed for nearly 10 years with very little known uptake or impact. It has become a maintenance burden. In several cases it dictates our code/library structure (for example necessitating LIBBITCOIN_CRYPTO_BASE), as well as build-system procedures (building multiple copies of object files especially for the lib).


What is the status of `LIBBITCOIN_CRYPTO_BASE`? Is it kept around or moved into libbitcoin_common?

I see it's mentioned here: https://github.com/bitcoin/bitcoin/pull/29180#issuecomment-1878604328 - would be useful to also add a note to libraries.md
