Detection and proper management for these edge cases when decoding BIP32 in Bitcoin Core has been proposed by

Stricter BIP32 decoding and test vector 5 by sipa · Pull Request #22836 · bitcoin/bitcoin

This adds detection for various edge cases when decoding BIP32 extended pubkeys/privkeys, and tests them using the proposed bitcoin/bips#921 BIP32 test vector 5.

in our library and have now entered BIP32 specifications

added test vector #5 for invalid extended keys by fametrano · Pull Request #921 · bitcoin/bips

The BIP32 specification lacks test vectors for invalid extended keys that should not be parsed as valid. Such test vectors are proposed here.

We are actually using it for production. Interfaces change between releases, so it requires maintenance work, anyway coupled with libsecp256k1 for sensitive stuff is a solid base library

Side note: I stumbled upon btclib in my search; while not recommended for production use, skimming the source shows genuine understanding of cryptography and BIP-340 in particular, eg. github.com/btclib-org/btc Kudos to the team (@Ferdinando1970 it seems).

Replying to

and

I endorse

: it's a Python3 type annotated library intended for teaching, learning, and using bitcoin. Rigorously and extensively tested, its test suite covers 100% of the code base and reproduces results from both informal and major reference sources.
