Each commit should leave the code in a valid state, so it would make sense to move 000c685bcdd395d61a58ad9698563cab41e2d7d0 up.

Concept ACK.

re "refactor: Use fixed size ints over (un)signed ints for serialized values"

i wonder if we can enforce this kind of thing? That only fixed-size values can be serialized, would make sense to avoid any kind of platform divergence. At least in theory, as we already make assumptions on these types it's not a pressing issue.

(https://github.com/bitcoin/bitcoin/pull/33849)
## Motivation
Add direct Boost unit tests for the asmap interpreter and validator so regressions in ASN bucketing are caught earlier. Existing coverage relied on indirect behavior through addrman tests; these new cases exercise `Interpret` and `SanityCheckASMap` without large fixtures.

## Changes
- Introduce `src/test/asmap_tests.cpp` with helpers to synthesize compact asmap programs and five focused tests:
- verifies match vs default routing
- rejects tables missing a `RETURN`
- r

A more thorough approach would be to introduce `typedef uint8_t HashType`, but it requires changes all over the codebase.

I would also prefer not breaking up this loop.

Since we do an early return here, it's nicer to make `sighash` (or `sig_hash`) not an optional, so below you don't need dereference pointers.

I (lightly) checked that the vectors match BIP 328 and that the test fails if I sabotage the input data.

Ideally we should not use `size_t` anywhere for on-disk sizes and offsets in the first place. It's meant for counters and in-memory sizes, at most. But it's probably not worth changing all of that in places where we don't actually expect to work with large files.

Good idea to update these docs.

Afaik the use of quotes depends on the shell environment, I don't think it's worth documenting.

More important is to point out that Bitcoin Core will use `--stdin` here, in order to support large PSBTs.

The term "IPC" could be confused with our multiprocess integration, maybe just use the wording from `hwi --help`:

> `--stdin Enter commands and arguments via stdin`

The original doc is wrong, there is _only_ `signtx`, no `signtransaction`.

`signtx` and its arguments, like all other commands, can optionally be passed via `--stdin`
