Every pass mints a verifiable cert.

One SHA-256 hash per pass. Stored on a public, append-only ledger anyone can read. Recruiters paste the hash, get back the rubric, not just a green check. No-PII by default: the cert never contains your resume. Revocable only if the underlying scenario is found broken, and we say so in writing when that happens.

ledger is the source of truth; the profile page reads from it; pass rate is per-track and printed on the rubric page

verify, recruiter flow

A recruiter pastes a hash. Gets back the rubric. Not just a green check.

paste the hash or the cert id from a candidate's profile or signature

verify ->

verify, the response

What the verifier returns.

The recruiter sees the cert id, the track, the weighted score, the per-dimension scores, the minted timestamp, the ledger block, and a link to the scenario list. Nothing about the candidate the candidate did not opt in to.

What is always returned: cert id, track, score, per-dim, timestamp, block.
What is returned if the candidate opts in: handle, linked profile page.
What is never returned: resume, email, employer history, IP, device.
Hash is checked against the ledger block hash; ledger is signed nightly.

no-PII, default

Your cert is not your resume. It is a hash.

The profile page is what a candidate shows; the hash is what a recruiter can verify. The two are linked only because the candidate opted in. Opt out and the hash still verifies, just without the handle next to it.

Default, cert lives in the ledger anonymously. Hash works.
Opt-in, profile page goes live. Handle attaches to the cert.
Recruiter-paid invite, hash is shared back to the recruiter only.
Right to be forgotten, profile down in 24h; ledger entries become hash-only.

I paste the hash into the verifier, get the per-dim back, and I am done, under three seconds. Five minutes saved per phone screen.
