Evidence, proof and selling tools for Black Box flight recorder

Level 1 Beginner: understand it

When an AI agent does something unexpected, the first question is "what exactly did it do, step by step?" Ordinary logs are scattered, editable and often missing steps. Black Box records each step of an agent run in a chain where every step is linked to the one before. At the end, the whole run is sealed with a signed fingerprint (a Merkle root).

If personal data has to be erased later (for example under GDPR), the content can be removed and the record still verifies, because the seal covers a fingerprint of the content rather than the content itself. Anyone can check a recording offline with no CAIN code. It can also export to OpenTelemetry, the common tracing format.

Think of it like this: An aeroplane's black box. After an incident, investigators do not ask the pilot what happened; they read the recorder. And the recorder is built so that nobody can quietly rewrite it.

Read the full plain-English explanation: Black Box flight recorder, explained.

• I read the explanation above.
• I can say what it does in one sentence, without notes.

Level 2 User: see it work

Run it live: open the live demo. Before each result, guess what will happen. These are checks it must pass:

• Record, seal, verify: A sealed recording verifies.
• Edit an event after sealing: Changing one event changes its hash and the root.
• Drop an event after sealing: Truncation is detected.
• Add an event after sealing: A sealed recording accepts nothing more.
• Inclusion proof against a made-up root: A proof must lead to the root it claims.

• I ran the live demo.
• I can explain what one of these checks shows.

Level 3 Verifier: prove it yourself

This is the skill that sets you apart: you don't have to believe us, and neither do your customers.

1. Install Python 3 if you don't have it (python.org/downloads).
2. Download the kit and unzip it.
3. Open a terminal in that folder. On Windows, click the folder's address bar, type cmd and press Enter. On a Mac, right-click the folder and choose New Terminal at Folder.
4. Run python3 verify.py (on Windows, python verify.py). It checks the seal without the internet.
5. Run python3 verify.py --live. It repeats every check from your own computer.
6. Try to cheat it: open transcript.json in a text editor, change one character, save, and run python3 verify.py again. It must now say FAIL. Unzip a fresh copy afterward.

• I ran the kit's check on my own computer.
• I changed a file and saw it fail.

Level 4 Expert: know the edges

An expert knows what a product does not do, and says it first. That is what makes a buyer trust you.

Read its limits page in full: what Black Box flight recorder does not do.

You can say

• Every step is chained and the run is sealed and signed.
• Personal data can be erased and the record still verifies.
• Anyone can verify offline with no CAIN code.

Never say

• "Records everything the agent does": it records what the integration sends.
• "Hardware-signed": software key.
• "Legal opinion on liability": it is evidence, not advice.

Read the questions real buyers send, with honest answers: answers to buyer questions.

Test yourself (click a question to see the answer)

• I got every quiz question right without looking.
• I can name one thing it does not do.
• I explained it to a friend, and they understood it.

Level 5 Seller: put it in front of a customer

1. Copy, paste, send: the shortest route, no technical skill needed.
2. Who buys it and where to find them.
3. The sales conversation, then the offer and the close.
4. The rules: read these before your first message.
5. Selling tools with this product's evidence built in: pitch, emails, call script, objection answers, one-pager.

• I read the rules.
• I sent my first personal message.
