+# Baseline entries seed the registry at boot so the agent has a
+# floor of known models before any probe runs. Entries are
+# structurally validated by MonkeyClaw.ModelRegistry.Baseline.load!/0
+# and then trust-boundary validated by CachedModel.changeset/2 inside
+# the registry's upsert funnel. Users can override or extend this
+# list in their own runtime.exs without rebuilding the release.
