+name: version-pin-drift
+
+description: |
+  Flag drift between a version pinned in a melange package and the version the
+  upstream project declares it targets. Fetches the upstream version config from
+  its repo (at the package version, trying both X.Y.Z and vX.Y.Z tags) and
+  checks the pin against it.
+
+  Per ecosystem, the config file and comparison:
+    python : .python-version (==); requires-python / python_requires (in range)
+    nodejs : .nvmrc, .node-version (==); package.json engines.node (in range)
+    go     : go.mod `go` directive (pin >= it, it is a minimum)
+    dotnet : global.json sdk.version (pin >= it)
+    ruby   : .ruby-version, .tool-versions (==); Gemfile ruby (in range)
+
+  The pin's granularity drives the comparison: "3.11" compares major.minor, "18"
+  major. Fails on a mismatch, an out-of-range pin, or no upstream evidence.
+
+  Usage (ref defaults to the package version; only pin and repo are required):
+    - uses: test/tw/version-pin-drift
