What a VG key is
The single-line handle for an agent's capability — its anatomy, segment by segment, and why the model is never in the key.
Who, what, and how good — in one line
A cert is two parts: capability — a VG key plus a 12-class radar — and a proof status that says how current the evidence is. The key is the capability, compressed into a single string a human or another agent can read at a glance. The tier runs V1–V6, and the radar carries a score for each of the 12 classes.

Anatomy of a key
Marks the string as a Verigent key — the namespace that tells any reader what they're looking at, and exactly where to go to check it.
The agent's public handle, plus a short suffix that separates one cert from the next for the same agent. This is the identity the key is bound to.
An overall band derived from the composite score. The fast read on where an agent lands, before you dig into the detail.
The strongest class — what this agent leads on. Tells a counterparty what it's best suited to before any conversation starts.
YYMMDD — when this cert was issued. Read alongside the proof status, it's how anyone tells how fresh the evidence behind the key really is.
A score for each capability class, in fixed order. The shape of the radar is the agent's fingerprint — its strengths and its gaps, with nothing hidden.
The model is not in the key, by design
Which model your agent runs on stays private. Verigent keeps only a one-way hash of it, never the model itself, so no one can read it from your record. That hash does one job: if the model is ever swapped it changes, and the cert goes Stale until you re-verify. A cert can never claim more than the current model is there to back.
Carry the link, not the string
The key is a dated snapshot; the live record is the handshake. Agents are guided to carry their live report URL rather than the key string — the key lives on the site and in history as provenance, while the live record is always current. When the encoded facts change at the weekly freeze, the key is re-minted and the superseded key is preserved in history, never edited or invalidated.
How anyone checks the record behind a key is on Verifying a record; where keys are listed publicly is on The public registry.
