In commit "doc: warn that CheckBlock() underestimates sigops" (0ac19a98f329fe8952f394509a7a29775ab805b0)

Might be good to say why this check is useful if it's not a problem for it to be inaccurate.

Might also be good if PR description mentioned motivation for the change. This all looks ok but it's a bit confusing because it's not clear what the context is.

Do people think i should change the value of the coinbase transaction used in the fuzz test here as well? I previously kept it along with the PR introducing validation for those fields, but since i change this in unit tests already it might make sense to do it here.

I might be missing something, but it would have to be a span of `CTxUndo`, and you'd have to move `WriteBlockUndo` to `ConnectTip` too, no? I wasn't quite sure about doing that change here though. The implications of separately writing the undo data and raising the `BlockIndex` validity level are not quite clear to me yet. There is always a question where to draw the scope line with these refactors. While it might not be useful to write undo data if we ever get to the alternative kernel API clie

Oh, i was just reading the diff and overlooked `WriteBlockUndo`! Yes that makes sense.

https://docs.python.org/3/library/subprocess.html#subprocess.TimeoutExpired.output claims:
> This is always [bytes](https://docs.python.org/3/library/stdtypes.html#bytes) when any output was captured

Can we simplify to:

```suggestion
child_output = e.output.decode("utf-8") if e.output else ""
```

?

I'm not a fan of a incomplete iteration, can we separate the generator expression to the first line, something like:
```suggestion
class_name = next((arg[16:] for arg in sys.argv if arg.startswith('--internal_test=')), None)
```
or use a regexp to deduplicate the match and substring (untested):
```suggestion
class_name = next((m[1] for arg in sys.argv if (m := re.match(r'--internal_test=(.*)', arg))), None)
```

do we need regular expression matching here or can we use `output.count("Traceback")` as well?
```suggestion
if (n := output.count("Traceback")) != 1:
```

nit: `assert False` is a bit hacky in my opinion - can we use the same style that we did on line 60?
```suggestion
print("Should have failed earlier during startup.")
raise
```

If I understand this correctly, we may want to preserve the seed properties - and xor preserves the distribution properties better than addition:
```suggestion
args.append(f"--randomseed={self.options.randomseed ^ hash(expected_exception)}")
```

Q: is `hash` expected to be stable between runs - or is that not important here?

💬 l0rinc commented on pull request "qa: Verify clean shutdown on startup failure":
(https://github.com/bitcoin/bitcoin/pull/30660#discussion_r2052904553)
Based on the checks we're doing on `e` at the top, `error_num` can potentially be `None` here - is that expected?

I have added a commit to also set nLocktime / nSequence for coinbase transactions created in fuzz targets.

> The churn in the first commit is pretty annoying.

@Sjors (from this and in-person discussions) i have split as much as possible of the changes from this commit into preparatory commits. Now there is in the main commit only the necessary churn to keep commits hygienic. Hopefully it helps.

Apparently migrating the legacy wallet to descriptors is also a way to fix this issue.

Removed the fix commit since we are expecting legacy wallets to go away soon, and migration is a valid way to fix this problem. The remaining test commit is updated to work without the automatic repair being logged. It additionally is changed to check that no `keymeta` records exist after the migration.
