Two-stage Dockerfile: the runtime image carries neither uv nor a build toolchain, runs as uid 10001, drops every capability and needs no writable filesystem (verified with --read-only and no tmpfs). k8s/ is what runs, dev/ is the Flux plumbing that applies it, self-managing after three manual applies — the same shape every kong-* repo settled on. Three choices worth naming: - One namespace for the estate. What isolates an agent is its Keycloak client and the audiences it may request, not a namespace boundary. - The GitRepository uses anonymous HTTPS rather than SSH with a Vault-held deploy key. The repo is already anonymously readable on gitea, so a key would guard nothing while adding two objects to create by hand before anything deploys. If the repos ever go private this becomes the kong-* SSH pattern. - The lab CA certificate is committed. It is a certificate, never a key, and checking it in means the deployment has no hidden prerequisite. replicas: 1 is a constraint, not a default — conversation history lives in the process, so a second replica would route a user's "yes" to a pod that never saw the question.
