+# tree-sitter-dart WASM (vendored)
+
+This directory ships a pre-built `tree-sitter-dart.wasm` because the upstream
+npm release does not.
+
+## Why vendored
+
+The published `tree-sitter-dart@1.0.0` (2023-02-24) tarball does include a
+`tree-sitter-dart.wasm`, but it was built with a pre-`dylink.0` tree-sitter
+CLI. `web-tree-sitter@0.26.x` — the loader this project uses — expects the
+newer `dylink.0` custom-section name and refuses to load the older format
+(failure surfaces in `getDylinkMetadata`).
+
+Rebuilding the same upstream grammar.js with a current
+`tree-sitter-cli@0.26.x` produces a `dylink.0` wasm that loads cleanly.
+
+## How to rebuild
+
+```bash
+npm install -g tree-sitter-cli@latest
+cd /tmp && npm pack tree-sitter-dart@1.0.0
+tar xzf tree-sitter-dart-1.0.0.tgz
+cd package
+tree-sitter build --wasm
+cp tree-sitter-dart.wasm \
+   /path/to/understand-anything-plugin/packages/tree-sitter-dart-wasm/
+```
+
+Verify the resulting wasm:
+
+```bash
+head -c 30 tree-sitter-dart.wasm | xxd | head -1
+# Expect: ...dylin / k.0...
+```
+
+## Provenance
+
+- Grammar source: `tree-sitter-dart@1.0.0` (publisher: amaanq) — `grammar.js`
+  unchanged, only the wasm artifact is regenerated.
+- Built with: `tree-sitter-cli@0.26.x`, `wasi-sdk-29-arm64-macos`.
+- License: MIT, inherited from tree-sitter-dart@1.0.0 (publisher: amaanq).
+
+## When to remove this package
+
+If amaanq publishes a refreshed `tree-sitter-dart` with a `dylink.0` wasm,
+this workspace package can be deleted and the dependency in
+`@understand-anything/core` flipped to the upstream package.
