Can I ask for a P2TR transaction id example past block 709632?
I was trying to debug one of my scripts and something is wrong when searching for witness_v1_keyhash, and couldn't manually find one in the blockchain explorers.

Taproot activated in block 709 632, but the first P2TR transactions were in block 709 635. A few P2TR transactions that may be useful for test vectors would be:
- 33e7…9036, the first P2TR transaction
- 3777…35c8, the first transaction with both a P2TR scriptpath and a P2TR keypath input
- 83c8…7d82 with multiple P2TR keypath inputs
- 905e…d530, the first scriptpath 2-of-2 multisig spend
- 2eb8…b272, the first use of the new Tapscript opcode

You could find all P2TR transactions via a blockexplorer for example on blockchair.com by filtering the transaction outputs for type(witness_v1_taproot) and is_spent(true).

For the final transaction you list, I see where the internal public key should be is: 0000000000000000000000000000000000000000000000000000000000000001. What does that mean in this context? Also I see the Schnorr signatures here are 65 bytes, but I thought Schnorr signatures were typically 64 bytes. In BIP 342, under "Signature Validation" it mentions this, but I'm not clear.

On mainnet there are a number of P2TR transactions in block 709635. A few transaction IDs are included in the index of my bitcoin-dev mailing list post.
