+    # LLM provider SDKs are now indirect deps owned by maestro-llms (the
+    # cut-over removed all direct imports). Their versions are pinned by
+    # maestro-llms's own go.mod and validated by its CI; bumping them here
+    # would only force an untested transitive version under the toolkit.
+    # Bump them in the maestro-llms repo instead — Maestro inherits via the
+    # (still dependabot-tracked) maestro-llms dependency. These churn often,
+    # which was a motivation for the extraction.
