CVE, NVD and the zero-day — the clock between discovery and patch
A zero-day is a vulnerability with no patch available, and the CVE/NVD system is the public clock tracking it from disclosure to fix — the window during which everyone is exposed and priced.
Not yet scoped.
Why
The PoC traces one CVE's lifecycle (report → embargo → disclosure → patch → exploitation) and the exploit market around it, framing patch latency as the real risk metric.

Where it lands in Jayverse
CI: track patch latency for the OpenZeppelin submodules and any other pinned dependency, not just whether a CVE exists. Alert when a fix has been available for N days and the pin hasn't moved.
Auditor: log each dependency upgrade's trigger, routine bump versus CVE response. So the "time exposed" number, not just "patched: yes/no," is visible in what Auditor publishes as checked.
