The module is intentionally compiled with TinyGo's wasm-unknown target and the no-scheduler mode. A standard Go GOOS=js GOARCH=wasm binary imports the gojs host module and requires wasm_exec.js, which is not a precompiled-Wasm Worker boundary. The only semantic vendored adaptation is the iterator boundary: the four goroutine/channel iterators in svg/iter.go (UpDownMinor, LeftRightMinor, DiagDown, and DiagUp) return slices in the same traversal order. Their existing range call sites use for _, value := range in ascii/a_drawable.go, ascii/a_line.go, svg/abstractcanvas.go, utf8/u_drawable.go, and utf8/u_line.go. The vendored source tree is derived from the Go module checksum recorded in go.sum with whitespace normalized; the complete repository fixture renders byte-for-byte identically to the pinned Docker binary.
