Why this digest exists

Most CVEs never move.
We watch the ones that do.

Exploitation probability spikes overnight. Public exploits land. CVEs cross into confirmed in-the-wild use. That movement, the change, is what ESIP scores and surfaces.

Silence is not clearance: a CVE that didn't move isn't a safe one, just one nothing has happened to that week. When something does move, that change is the exposure signal.
