Every technique in Book 4 of the Digital Sovereignty series was carried out before it was written down: rolling a seed, building a passphrase, a restore drill from the steel backup, 2-of-3 multisig, the heirs package. The sheets that came out of that work are here to print. Free, no sign-up, with a checksum for every file. Each sheet names the chapter it belongs to. You can use the sheets without the book, but the reasoning is in the book.
⚠ No seed is ever written on any of these sheets
The sheets carry dice digits, fingerprints, device labels and check marks, but no recovery words and no passphrase. The dice logs are the exception that proves the rule: the sequence of digits is the seed. Treat a filled-in dice log like the steel backup, or destroy it as soon as the backup has been verified.

The sheets one by one
All single-sided A4 (the passphrase sheet runs to 15 pages because the word list belongs to it). Chapter numbers refer to Book 4.

The verification script
Way 2 from the Dice Check guide: verify_dice_seed.py turns 50 or 99 dice digits into the BIP39 words in the terminal,
around 90 lines of Python without third-party libraries. It asks for the digits instead of taking them as an argument (so they stay
out of the shell history) and it runs on Tails with no network. The wrapper dice-check.sh checks the script and the word
list against the supplied checksum list before every start. Use it with a throwaway seed only, never with the real one.

These four files are language-neutral, which is why their checksums are identical to the ones in the German package. The scripts themselves still answer in German, for example "Selbsttest ... OK" for a passed self-test. If you would rather read English, the browser tool Dice Check does the same calculation with an English interface.
The checksums on this page are the second channel: a file that brings its own comparison value along verifies nothing. All four files are inside the ZIP as well.
The tools that go with them
Dice Check recomputes the SeedSigner rolls in the browser, offline, one single file. Estate Planner produces the forms of the heirs package, offline, without a seed and without amounts. Both are free and both carry a checksum on their own page. The Estate Planner covers German inheritance law, so check what applies in your own jurisdiction.
License and sources
The sheets may be printed as often as you like for your own use. The passphrase sheet contains the EFF Long Wordlist (CC BY 3.0 US, Electronic Frontier Foundation). The BitBox Diceware method on dice log 1a follows the guide by Shift Crypto, the original including the word table is at bitbox.swiss (CC BY-SA 4.0). Always read the current version there alongside it, because firmware changes can shift the procedure. The verification script is published under the MIT license.
