A BIP39 seed phrase (12–24 words), possibly with typos

Put the phrase in in/seed.txt. The agent-safe commands below run in the sealed image through ./blocktools run, which prints public data only (addresses and paths, with every key replaced by [REDACTED]).

1. Is it a seed? (classify prints a fingerprint, never the words)

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

2. Repair typos and list addresses on every chain

seed-repair fixes misspelt words and checks the checksum. Test vector: the BIP39/BIP84 spec phrase "abandon ×11 about" with two typos.

./blocktools run 'seed-repair < /in/seed.txt | seed-to-master | derive --chain btc,eth,tron,sol,xrp --count 1'

Each expected address comes from an outside source: the BIP44/84 spec, MetaMask's address for this phrase, TronLink, Phantom (m/44'/501'/0'/0') and the XRPL BIP44 vector.

3. With a BIP39 passphrase ("25th word")

Put {"passphrase":"..."} on the first line of the input, or let the human type it (seed-to-master --passphrase-prompt, via ./blocktools reveal). A wrong passphrase still gives valid but empty addresses, so check balances (goal-check-balance.md).

4. Front door: balance, then sweep

recipes/recover.sh /in/seed.txt - --goal balance

The sweep (recipes/recover.sh in/seed.txt DEST) is in goal-sweep.md. If the wallet used odd paths, see derive.md.
