We did not drop the 13 `tree-sitter-` npm deps +from `packages/ingestion/package.json` — they remain installable, just +not default. `isNativeAvailable()` still probes them at runtime. + +**(Q3) Kotlin / Swift / Dart.** Their npm packages ship only native +`.node` bindings. The obvious workaround — the `tree-sitter-wasms` +catalog package — is unusable: its 0.1.13 artifacts were built with +`tree-sitter-cli` 0.20.x, which emits the legacy `dylink` custom +section. `web-tree-sitter` 0.26+ hard-rejects anything that's not the +standardized `dylink.0` section. We verified this at the byte level +(python grammar ships `dylink.0`; tree-sitter-wasms ships `dylink` and +throws at load). So we build our own `.wasm` blobs once, from the +exact grammar sources we pin, and commit them to +`packages/ingestion/vendor/wasms/`. The build script at +`scripts/build-vendor-wasms.sh` reproduces the build via docker / +podman / finch / local emsdk and takes ~3 minutes end-to-end.
