- Around line 1297-1300: Update the DoppioJVM section’s data-i18n bindings from
language-info:java.desc and language-info:java.link to
language-info:javaDoppio.desc and language-info:javaDoppio.link. Then remove the
obsolete java locale entry only if no other section references it, preserving
the existing javaDoppio translations.

Important
npm run test:i18n-export (part of npm run test and the prepush hook) fails on this branch: the java-doppio info section binds language-info:java.desc/java.link instead of the new javaDoppio.* keys, so the committed en locale no longer matches the regenerated output. The fix is small but must land before merge — details inline.

ℹ️ No unit specs for the new language modules
Other new WASM languages ship a co-located __tests__/lang-<lang>.spec.ts asserting name/title/extensions/scriptType/compiledCodeLanguage/scripts/factory, and test:unit runs in CI. This PR adds only an e2e case; consider adding lang-java-wasm.spec.ts and lang-java-doppio.spec.ts to match the convention.

Important
The three commits reviewed here are sound, but the PR should not merge yet: two must-address threads from the previous review on src/livecodes/languages/java-wasm/lang-java-wasm-script.ts are still unaddressed — the runtime is still cached in module scope (so every live-reload edit re-creates and leaks the ~8MB runtime), and livecodes.java.loaded is still resolve-only (a boot failure leaves the starter stuck on "Loading..." with a null output).
Reviewed changes
Reviewed the three commits pushed since the prior pullfrog review (unit specs + tooltip i18n keys, non-en locale translations, and the java-doppio → java-8 rename).
java-doppio→java-8rename — engine files, docs, thelanguage-info.htmlsection,enand non-enlocale keys, thescripts/build.jsiife entry,sdk/models.tsunion, and extensions (['java-8', 'java8']) renamed consistently;javanow aliasesjava-wasm.- Runtime load-race fix —
lang-java-wasm-script.tsnow polls forwindow.JavaWasmbefore callingcreateRuntime, correctly reflecting thatcompiler.scriptsare injected as async classic scripts. - i18n fix — the second info section now binds
java8.desc/java8.link;npm run test:i18n-exportpasses (verified) and the stray 5th link item is gone. - Unit specs — added
lang-java-wasm.spec.tsandlang-java-8.spec.ts(11 tests pass). - Docs/e2e —
java.mdxrewrite, newjava-8.mdx, and the e2e case now passes code via the URL param.
ℹ️ Skills language reference not updated for the rename
.agents/skills/livecodes/language-support/references/languages.md is the canonical list of supported languages and aliases and is expected to change when a language is renamed or added; it still has only | Java | java | Java runtime | (line 129) and maps .java to Java (line 255), with no java-wasm/java-8/java8 entry.
Technical details
# Skills language reference is stale after the rename
## Affected sites
- `.agents/skills/livecodes/language-support/references/languages.md:129` — `| Java | `java` | Java runtime |` now describes what ships as `java-wasm` and omits `java-8`
- `.agents/skills/livecodes/language-support/references/languages.md:255` — `.java` extension mapped to `Java`
## Required outcome
- The reference table reflects that `java`/`java-wasm` select the TeaVM compiler and `java-8`/`java8` select the Doppio engine.
## Suggested approach
- Split the row into `Java (Wasm)` (`java-wasm`, alias `java`) and `Java 8` (`java-8`, alias `java8`); keep the `.java` extension mapping on the default (`java` = Java (Wasm)). Not CI-enforced.deepseek-v4.1-flash (free via Pullfrog for OSS) ｜ 𝕏
