-# Forgejo runner (local chart), single generic "docker"-labeled instance.
-# Being retired in favor of three language-specific instances of the same
-# chart (forgejo-runner-golang/-node/-rust). Added here ahead of that removal,
-# in its own commit, so it syncs BEFORE the Application is deleted -- a
-# non-cascading delete would otherwise orphan this Deployment, its dind
-# sidecar and both PVCs (same lesson as the Kong retirement).
+# Forgejo runners (local chart, one instance per language), replacing the
+# single generic "docker"-labeled runner. Each instance is a full standalone
+# Deployment with its own dind sidecar, own PVCs (registration + layer
+# cache) and own registered label -- there is no shared generic runner
+# anymore, so each instance also builds and pushes images for the repos it
+# serves (the chart's ConfigMap/NetworkPolicy fixes for that -- valid_volumes,
+# network: host, egress to ingress-nginx -- apply identically to all three).
+#
+# `values.yaml` is the chart's default and doubles as the golang instance's
+# config; node and rust layer a small values-<lang>.yaml override on top for
+# just runner.name/runner.labels. All three share one runner-token Secret
+# (Forgejo registration tokens are reusable across multiple runners, unlike
+# GitHub's one-time tokens) -- if that assumption is ever wrong, registration
+# will fail loudly in the register initContainer's logs, not silently.
