Evidence, proof and selling tools for Verify-yourself page

Level 1 Beginner: understand it

One web page, eleven checks. Each one calls the live production system from the visitor's own browser and re-computes the result from the reply it just received: are the servers healthy, do signatures verify, does a known attack get blocked, is the evidence chain anchored in the public Sigstore Rekor log.

It is the fastest way to turn a sceptic into a listener.

Think of it like this: Letting a buyer test-drive the car on their own route, instead of showing them the brochure.

Read the full plain-English explanation: Verify-yourself page, explained.

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:

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.

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.

Never say

Is it independent?

No; it runs in your browser.

Do we sell it?

No.

In the live check "Digest changed", what answer must come back, and why?

"NOT_VERIFIED". The quorum signed this digest, not yours.

In the live check "CODEGUARD: curl piped to sh", what answer must come back, and why?

"DENY". Denied live.

In the live check "FlowGate: cyclic plan", what answer must come back, and why?

true. Recomputable by hand.

Does a passing kit prove the product is safe for every possible input?

No. It proves what the live product answered to the inputs listed in the kit, and lets anyone check that again.

Has an independent party audited or certified this product?

No. No third-party audit is complete and no certification is held. Say so if asked.

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.

About money: 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.
