A BIP32 master private key (xprv)

A one-line xprv… (for example exported from a wallet's "show master private key"). The test input is the BIP84 spec mnemonic's root key (abandon ×11 about) in xprv form. BIP84 gives bc1qcr8te4… as its first receive address.

./blocktools run 'classify /in/xprv.txt'


recipes/recover.sh /in/xprv.txt - --goal addresses --count 1

recover.sh wraps the line as {"xprv":…} with sed, streamed (never in a shell variable), and pipes it into derive --chain C, so --chain and the presets in derive.md apply. Sweep is the same as for a seed (goal-sweep.md). NOT BUILT: yprv/zprv/tprv lines (derive takes the xprv form only; convert the version bytes yourself) UNTESTED: account-level xprvs (derive applies its path from the key it is given; use derive --path to match).
