Live evaluation · nothing leaves your device

Test the CPU cascade — in your own browser.

This page runs the NI-Stack Stage-1 automaton — the same linear-time Aho-Corasick algorithm and the same threat-keyword map as the production system — entirely on your machine. No API call, no upload, no account. Turn off your Wi-Fi and it still works. That is the sovereignty claim, demonstrated rather than asserted.

🔒Sovereign mode: this scan runs locally in your browser — your text is never transmitted.

Everything above executes in client-side JavaScript. Open your browser's network tab — you will see no request when you scan.

Exactly what this demo is — and is not.
  • Is: the real Stage-1 Aho-Corasick automaton + the real production threat-keyword map (10 categories), with the production cumulative-severity block rule (threshold 7).
  • Is not: the full cascade. Production adds a regex verification pass (which suppresses false positives this demo may show), plus further layers — semantic-intent classification, Unicode normalisation, entropy analysis, drift tracking, pattern memory — and an optional on-premise content-safety model.
  • So: the headline 97.7% TPR @ 4.0% FPR belongs to the full cascade at its tuned operating point, not to this Stage-1 page. Reproduce that number yourself with the eval kit below.
  • And: that 4.0% false-positive rate is English-tuned — benign non-English text is over-blocked (~16%, measured and published in our second preprint).
  • Severity weights shown here are this demo's; production weights, the regex verification set and the later layers are part of the licensed IP.
Step 2 — reproduce the real numbers

Don't take the headline on trust. Regenerate it.

The measured two-number scorecard comes from an open harness over 100% public corpora — no NDA, no private test set. A technical evaluator can rerun it end to end.

The evaluation kit

Reproduces the injection/content scorecard against public corpora (hackerprompt, jailbreakhub vs OR-Bench) and writes a dated JSON manifest.

Kit + step-by-step (BUYER_REPRODUCE.md) is released to evaluating partners with the reference implementation — request it below.

Verify a signed receipt

Every cascade verdict can emit a post-quantum-signed, RFC-3161-timestamped receipt. Check a real one offline against our published did:web key — our servers are never contacted.
