Infrastructure and security notes

Reliability and security share a root: defined boundaries, least privilege, and evidence you can audit.

2026-06-01notes

Infrastructure, reliability, and security are usually discussed as separate concerns. In production systems, they share the same foundation: explicit boundaries and evidence you can inspect.

The overlap

A webhook handler that logs raw payloads is a reliability convenience and a security incident. A tool-calling agent without scoped credentials is an orchestration demo and an access-control hole. A memory store without tenant filters is a retrieval feature and a data breach.

What I want this series to cover later

  • Secret handling in agent traces.
  • Tenant isolation in retrieval.
  • Supply chain and CI runner trust.
  • What “eval data” is allowed to contain.
