Prove it · live
Don’t trust us. Watch your browser verify us.
Below is a real, freshly-signed Queldrex proof bundle for a poisoned tool we caught: the signed ruling, a Proof-of-Detection committing to exactly what the scanner judged, and an inclusion + consistency proof over our live public log. Your browser recomputes every one of them right now, with its own Web Crypto, no Queldrex code, and checks our answer. Three independent implementations (this page, our server, and the published @queldrex/verify) agree on the same bytes. That agreement is the proof.
Live verification
1 · Decision Receipt
Ed25519 signature verifies against the receipt’s own public key
2 · Proof-of-Detection
record commits to exactly the shown input (input commitment)
detection hash equals the hash signed into the ruling
3 · Transparency log
inclusion proof reconciles to the live published root (RFC 6962)
consistency proof: the live log only ever grew (RFC 9162)
Verifying in your browser…
Everything above runs client-side against the bundle rendered into this page. Nothing here reads our server’s “valid: true”; each check reconstructs the answer from the signed bytes and the receipt’s own embedded public key.
Run it yourself, one command
The same bundle is served as JSON at /api/trust/demo/proof. Verify it with the published zero-dependency package, the exact verifier a customer or auditor runs in CI.
# in the queldrex repo
node scripts/prove-it.mjs # verifies the live bundle, exits non-zero on any failure
node scripts/prove-it.mjs http://localhost:3000 # or against a local dev server
# or from scratch with the published package
npm i @queldrex/verify
node -e "fetch('https://queldrex.com/api/trust/demo/proof').then(r=>r.json()).then(async b=>{
const v = await import('@queldrex/verify')
console.log('ruling ', v.verifyReceipt(b.decision.receipt))

})"What was caught
The subject is a canned poisoned tool that is ours, so its raw text is shown (a real customer’s input is never exposed, only its hashes). A prompt-injection payload is smuggled into the tool description; the call arguments carry an SSRF cloud-metadata URL. The ruling: deny under QX-L-0002.

}Honest scope: the signature, detection, inclusion, and consistency checks are all offline-verifiable today. The RFC 3161 timestamp anchor is not yet checked by the npm verifier, so this bundle makes no timestamp claim. That check ships with verifyTimestamp().
