Summary
tinyminiscript rejects a valid taproot descriptor whose internal key is given as a standard 32-byte x-only pubkey.
Minimal repro
tr(a34b99f22c790c4e36b2b3c2c35a36db06226e41c692fc82b8b56ac1c540c5bd)
Observed behavior
The parser rejects with:
InvalidXOnlyKeyLength { key: "a34b99f22c790c4e36b2b3c2c35a36db06226e41c692fc82b8b56ac1c540c5bd", position: 4, found: 64 }
Cross-check
The same descriptor is accepted by:
rust-miniscriptbitcoin/bitcoinembitbitcoinerlab/descriptorsNBitcoin
Why this looks like a real bug
The taproot key parser currently requires 66 or 130 hex chars, which means it accepts compressed pubkeys and converts them to x-only form, but rejects the standard 64-hex x-only encoding used directly in tr(...).
