Narrow Highway · verification

Every number in your quote. Checked. In thirty seconds. Free.

Paste a quote, an invoice, a spec, or any document with numbers in it. Deterministic verification checks every quantitative claim. No AI guessing. No account. No sales call.

Nothing is stored. Only the numbers you paste are checked.

Checking is free. Keeping is paid.

Anyone can verify anything here, forever, free. Shops that want their evidence to accumulate pay for the keeping: every job sealed, every signature witnessed, every step walked, your audit package regenerated on demand from work you already did.

The traveler

Your job's paper trail, digital, signed at every step, impossible to skip a step, sealed when it ships.

The audit package

AS9100 evidence prep collapses from weeks to one command. Generated from your sealed records, not assembled by hand.

The record

Append-only, cryptographically chained, yours. When a customer, an auditor, or a prime asks how you know, the answer is a link.
