Evidence from the diff
The patch updates electrum/plugins/ledger/ledger.py to support Ledger Nano Gen5. It changes the comment for USB product ID (0x2c97, 0x0008) from ‘RFU’ (reserved for future use) to ‘Nano Gen5’, adds 0x80 -> ‘Ledger Nano Gen5’ to the MODEL_IDS map, and adds a product_key match returning ‘Ledger Nano Gen5’. No cryptographic, protocol, or access-control code is modified.
