Live demo call script
1. Show the normal case Do: Open https://cainstudio.online/top25-decision-receipts-lab.html and run: Genuine receipt verifies Say: A real receipt from the live gate checks out. 2. Now the attack Do: Run: Receipt with decision flipped to ALLOW on a DENY Say: The signature covers the decision. 3. Now the attack Do: Run: Receipt for a different command Say: A receipt is bound to the exact action it decided. 4. Let them check you Do: Send the kit link and ask them to run python3 verify.py --live on their own computer. Say: They don't have to take your word for any of this. That's the point. 5. Say the limit yourself Do: Tell them what the kit does not show. Say: Say it before they ask. It costs nothing and it earns trust.
When they push back
Does a receipt prove what happened next?
No: it proves what the gate decided. Pair it with the Black Box recording for what ran.
Is the key in hardware?
Software key on our host today; we say so.
Do all your products issue these?
Today only CODEGUARD; other products have their own signed formats.
Why should I believe your numbers?
You shouldn't have to. Run the kit on your own computer: https://cainstudio.online/ihvrk-decision-receipts.html. It re-sends every request and compares the answers, using no code of ours.
What doesn't it do?
Written down here: https://cainstudio.online/top25-decision-receipts-limits.html
Are you SOC 2 or ISO certified?
No, we hold no certification. What we offer instead is evidence you can check yourself.
Has anyone independent tested it?
No third-party audit has been completed. The attack cases in the kit are our own. I'd rather tell you that now.
Who else uses it?
We are an early company. I can show you the product working and the evidence, not a customer list.
It found nothing. So we're safe?
No. It means none of its checks fired. It doesn't prove something is safe.
How much is it?
Receipts are part of the CODEGUARD $500 30-day pilot. Lead with them when the buyer is a compliance or audit person.

The rules
- Send each message yourself, one person at a time. No bulk lists and no automated sending.
- Commercial email needs your real name, a real postal address and a way to opt out, and you stop when someone asks (US CAN-SPAM; many countries are stricter, so check yours).
- Never change a number, invent a customer, or say certified, audited or guaranteed.
- Only test a system the client owns or operates, after they confirm it in writing.
- Your share is agreed in writing with FIRME AI CORPORATION before your first message (email vincent@firmeai.com). Nothing here promises income. Most messages get no reply; that is normal.
