Fresh transaction pathRun and verify one new real case

The video story's next cold-chain shipment was assessed by ProofPay, signed from a local funded key, and recorded on Casper Testnet. The commands below reproduce the same path for another case.

1. Use the video-integrated case

Fresh follow-on cold-chain shipment on the same buyer, supplier, and trade lane used in the demo story.

examples/video-integrated-cold-chain-real-case.json

2. Generate a fresh ProofPay payload

The output includes the agent decision, evidence hash, decision hash, and Casper session args.

npm run realcase:prepare -- examples/video-integrated-cold-chain-real-case.json

3. Inspect the transaction command

This is a dry run. It prints the exact Casper Testnet transaction command without signing.

npm run realcase:deploy:print -- examples/video-integrated-cold-chain-real-case.json

4. Sign locally with a funded Testnet key

Private keys stay on the operator machine. The server never receives custody keys.

CASPER_SECRET_KEY=/absolute/path/to/secret_key.pem npm run realcase:deploy:testnet -- examples/video-integrated-cold-chain-real-case.json

5. Verify the public API path

The same evidence JSON now verifies through the hosted API against the recorded fresh transaction.

curl -X POST https://casper-proofpay-agent-web.vercel.app/api/real-case/prepare -H 'content-type: application/json' --data @examples/video-integrated-cold-chain-real-case.json
