+**Applies to:** Changes in `.github/workflows/`, `infra/`, `org/` repos, and template repos (CI workflows, kustomize configs, RBAC manifests, deployment scripts)
+
+**Rule:** If the PR contains ONLY infrastructure changes (no plugin code changes), use Pipeline B and skip UAT. Patty's time is reserved for user-facing feature testing.
+
+**Detection:** If `git diff` shows changes only in `.github/`, `infra/`, `org/`, or deployment files → Pipeline B. If any `headlamp-*-plugin/` code changed → Pipeline A.

 ### Stage 1 — Engineer Opens PR
 
 1. Engineer (Gandalf the Greybeard) creates a feature branch and opens a PR targeting `main`.
 2. CI runs automatically: lint, type checks, unit tests.
 3. CI must pass before any reviewer spends tokens. If CI fails, the engineer fixes it.
