AGENDA ITEM 1: "Should we migrate auth to microservices?"

  Architect (Opus):
    "Microservices give us independent scaling of the auth layer.
     Token validation can scale separately from session management."

  → broadcast to Security + Pragmatist

  Security (Codex):
    "Microservices mean more network boundaries = more attack surface.
     Service-to-service auth adds complexity. mTLS? JWT forwarding?"

  → broadcast to Architect + Pragmatist

  Pragmatist (Gemini):
    "We have 3 engineers and a 6-week deadline.
     Microservices migration is a 3-month project.
     Can we just add a reverse proxy and call it done?"

  → broadcast to Architect + Security
