Diagrid gives failed AI agents a way to resume

Diagrid launched Catalyst 2.0, a layer for AI agent frameworks that records model calls, tool calls, and handoffs as durable workflow steps.

If an agent is interrupted, it can restart from the last completed step instead of rerunning earlier work.

The update adds workflow-history signing with chained SHA-256 digests and SPIFFE-based identities.

This makes agent activity easier to verify later and helps detect tampering in enterprise environments.
