+# ⚠️  KEEP THIS FILE MINIMAL.

+# This .gitignore is inherited by every student fork. Anything listed here
+# is something a student CANNOT `git add` without `-f`. So this file must

+#   (a) instructor-only paths (refs/), and
+#   (b) machine-generated junk that NOBODY should ever commit.
+#
+# Do NOT add lab DELIVERABLES here (scan reports, SBOMs, go.sum, k8s
+# manifests, CI workflows, Dockerfiles, playbooks, dashboards, …). Students
+# are told to commit those in their submission PRs — ignoring them upstream
+# silently breaks the lab. When in doubt, leave it OUT of this file.
