Those outputs look like multisigs that are composed out of valid compressed or uncompressed pubkeys, and I believe spending them would pass standardness rules (except for 3482ea1d219120b13f3be49f63fd7079136785dff2bf7487726b640da5876e33:0, which appears to simply be a broken script).

The UTXO's I'm looking for would have pubkeys with an invalid prefix, or an invalid length for their prefix.

I notice that `CTransaction::ToString()` prints the inputs and the input script witnesses additionally, with that change script witnesses will be included duplicated. The order there is first all inputs, then all witnesses. Please consider removing the duplication.

Yes. I commented out the line on purpose to discover ways to improve the tests.

I suggest splitting into two commits:
- Preparatory rename & new parameter(s) but without behavior change, to minimize diff in 2nd commit (rename ALWAYS to FORCE_FLUSH I suppose)
- Change in behavior in the respective places (`scantxoutset`, `gettxoutsetinfo`, etc.)

Maybe this could come before the derivation-path-filling loop above. That way the early exit condition on missing sighash comes earlier, and the loop does not have to be broken into two.

It seems the proper, but much higher impact solution would be to change the `nHashType` field to `uint8_t`, what do you think? Maybe create a separate issue or PR for that?

I don't think this is strictly necessary, since we only ever have a single validation interface registered internally at a time. However, I think we should mimic our own internal code's behavior here and always unregister manually first.

💬 TheCharlatan commented on pull request "kernel: Introduce C header API":
(https://github.com/bitcoin/bitcoin/pull/30595#discussion_r2483649981)
I ended up removing this altogether. This was introduced before I had a coherent flushing strategy for the chainman and before we had smarter regular flushing in validation. As such, I don't think it is useful anymore to force a flush here. Maybe we can re-introduce it when we eventually expose interfaces for allowing programmers to control the way data is written.

💬 TheCharlatan commented on pull request "kernel: Introduce C header API":
(https://github.com/bitcoin/bitcoin/pull/30595#discussion_r2483657499)
Yes, we might expose more information here later, and the split between between the enums might also be useful if we ever expose a `TxValidationState`.

(https://github.com/bitcoin/bitcoin/pull/33755#issuecomment-3476337221)
Bitcoin Core relay policy is largely motivated by not relaying third party malleable transactions. There is no reason to relay transactions if they are just going to be modified before they get mined.

Given the, unfortunately extensive, amount of malleability generally afford by Bitcoin Script's design, sometimes policy just limits third party malleable transactions to some canonical form, one that minimizes transaction size so that miners are not incentivized to reduce the size further. He

@TheCharlatan I touch on this in the above, but I do want to explicitly note that the order of public keys that Counterparty uses changed in response to #5247 and the [the keys used to be in the other order](https://github.com/CounterpartyXCP/counterparty-core/commit/f1a8c82914b2f913560496e3d1becc1b63f88118#diff-b9154ac64e110b5561c5bcadc77b532aaea3f44eb53e9c4a76ae2ed3c6fad8b8L231-R261).

> Why make verbosity optional, and not keep as-is?

It allows reusing this function also for the new REST endpoint (`/blockpart/`) which doesn't support JSON response format.

> Where is it called with a null value?

It is called by `rest_block_part()` here:
