+# Bump the vllm-metal pins in the vLLM backend's darwin (Apple Silicon) install
+# path. The macOS/Metal build (backend/python/vllm/install.sh, Darwin branch)
+# installs vllm-metal, which is version-locked to a specific vLLM source release.
+# Two values must move together:
+#   VLLM_METAL_VERSION -> the vllm-metal GitHub release tag (its prebuilt wheel)
+#   VLLM_VERSION       -> the vLLM source version that release builds against
+# vllm-metal declares the latter in its OWN install.sh as `vllm_v="X.Y.Z"`. This
+# script reads both from vllm-metal's latest release and rewrites them atomically
+# -- mirroring bump_vllm_wheel.sh, which does the same for the Linux cu130 wheel.
+#
+# This deliberately tracks vllm-project/vllm-metal, NOT vllm-project/vllm: the
+# darwin build can only use the exact vLLM version vllm-metal supports, so it may
+# lag the Linux pin (requirements-cublas13-after.txt) until vllm-metal catches up.
