fix(wallet): add support for bip-431 rule 2#478
Conversation

cc @yan-pi as he already reviewed the other PR and has a reproducible test using bdk-cli too. |

I noticed in CI I need to fix some bdk_testenv/electrs/esplora related issues. However, the fix in bc05f88 is ready for review/discussion. |

IMO The is_truc helper is more functional and reads cleaner than the XNOR in #442, and definitely is a good foundation for the rest of #477.
Tested it locally by checking out test/unconfirmed-truc-txs and rebuilding the rust-repro binaries from https://github.com/yan-pi/bdk-pr442-repro against the PR via [dependencies] bdk_wallet = { path = "../../bdk_wallet" }:
The inverse direction of Rule 2: the non-v3 unconfirmed UTXO was filtered correclty.
One concern not flagged inline: the integration test is great, but maybe the unit-level coverage from #442 is also worth keeping?
Plus two minor nits and typos.

- introduces a private method `is_truc` to check if a given tx version is TRUC (e.g `transaction::Version(3)`). - add new step in `filter_utxos` to validate BIP-431 rule 2, which validates the proper usage of unconfirmed TRUC/non-TRUC ancestor in a TRUC/non-TRUC tx.

- introduce `test_create_and_spend_from_tx` to exercise BIP-431 rule-2 filtering in-memory, not relying on `bdk_testenv`/`bdk_electrum`. NOTE: I asked Claude to remove the `bdk_testenv` dependency, keeping the test behavior in-memory. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Description
I've tried this another approach in order to add support for BIP-431 rule 2. I think this way is clearer and more functional than the previously attempted in #442.
It introduces a new private helper method
is_truc, it's useful as this validation will be necessary for other BIP-431 rules. Also, it adds a new filter intofilter_utxosin order to filter out unconfirmed UTXOs from non-TRUC/TRUC txs.It also introduces the usage ofbdk_testenv, as there's some validation that is checked under node policy level.Notes to the reviewers
Let me know what you think about this one.
