+## GitNexus vendor notice
+
+This directory is a GitNexus-managed vendored copy of the official
+`tree-sitter-swift@0.7.1` npm runtime package, including its official native
+prebuilds. GitNexus keeps the top-level `tree-sitter` dependency pinned to
+`^0.21.1` until the broader parser runtime upgrade is handled separately.
+
+When updating this vendor package, replace it from an official
+`tree-sitter-swift` npm release, keep the native `prebuilds/` artifacts, update
+the `_vendoredBy` provenance fields in `package.json`, and verify the packed
+GitNexus tarball can load `tree-sitter-swift`.
