P2MR script-path spend of input 0

The node checks this spend by hashing the revealed leaf, walking the Merkle path in the control block up to a root, and requiring that root to equal the output's 32-byte witness program. This page recomputes the same steps.

Tripwired leaf (leaf version 0xe0)

M3 is an experimental rule of this test network, not part of BIP-360. From height 30000, nodes run leaves of version 0xe0 as tapscript; once the drill tripwire is spent, from the next block on, elliptic-curve signature checks in such leaves fail.

This page marks only the leaf this spend took. The output's other leaves stay hidden in the spend, so the page says nothing about whether another path could spend the output.
