ℹ️ No critical issues. I verified the implementation end-to-end against the pinned runtime package; the one nit I found (docs thumbnail) is already raised in the existing inline review.
Reviewed changes
janet-wasmlanguage spec (lang-janet-wasm.ts) — pass-through compiler,text/janet-wasmscript type,liveReload: true; registered inlanguages.tsand the SDKLanguage/TemplateNameunions.- Result-frame runtime + worker (
lang-janet-wasm-script.ts) — reuses the sharedcreateWorkerRunner/runCompiler/createLoadingReporterhelpers, follows the establishedloaded/failed/input/run()contract, and caches the runner onwindow.livecodes.janetWasmso live reload stays warm. - Starter template (
janet-wasm-starter.ts+janet.png) and its registration across the starter index, the template maps (functions/vendors/templates.js,server/php/inc/starter-templates.json), docs lists, command menu, and storybook. - Docs + i18n (
docs/docs/languages/janet-wasm.mdx, thejanetWasm.*andtemplates.starter.janet-wasmkeys) and tests (unit spec + two e2e counter tests).
I confirmed on the CDN that @live-codes/janet-wasm@0.1.0 is an IIFE that sets self.janetWasm, exposes createInterpreter({ baseUrl }) → run(code, input) → { output, errors, exitCode, ... } with the documented exit codes, and ships assets/janet/janet.js + assets/janet/janet.wasm at the constructed baseUrl. No janet grammar exists in the bundled Monaco/CodeMirror/Prism editors, so the absent editorSupport is correct. tsc --noEmit, the new unit spec, prettier, and eslint on the new files all pass. Docs wording and the janet.svg thumbnail nit are already covered by the existing inline review, so I won't duplicate them.
ℹ️ Non-English locale keys
templates.starter.janet-wasm and language-info:janetWasm.* are added only to the en locale, so every other locale falls back to English. Not required (and not CI-enforced), but recent language PRs have shipped real translations — worth doing for consistency.

Reviewed changes
This run reviewed the delta since the prior pullfrog review (c6842e5) — the single commit eaa6b04 ("janet editor support"), which wires syntax highlighting into the Janet spec and corrects the docs thumbnail.
- Added editor support to
janet-wasm— Monaco loads.../janet.jswith an explicitlanguage: 'janet', CodeMirror loadscodemirror-lang-janet.jsand calls.janet(), and CodeJar falls back to the Prismclojuregrammar. - Bumped
codeMirrorBaseUrlfrom@live-codes/codemirror@0.4.4to0.4.5, the first release shippingcodemirror-lang-janet.js; the published file list is purely additive, so no other CodeMirror language is affected. - Fixed the docs template thumbnail from
janet.svgto the checked-injanet.png, addressing the earlier CodeRabbit inline.
I confirmed on jsDelivr that @live-codes/codemirror@0.4.5 ships build/codemirror-lang-janet.js exporting janet() (a Lezer LanguageSupport, matching the shape used by cpp/go/java) and that @live-codes/monaco-languages@0.3.11 ships dist/janet.js registering language id janet. tsc --noEmit, the janet unit spec, prettier, and eslint on the changed files all pass.
