-- Module split of `index.html` (no build step) is briefed in `docs/v2/REFACTOR-PROMPT.md`. It produces the
-  pure pieces a Swift port reads from: covers math, sheet contract, brain, DJ prompts.
+- **The module split is done on the `split` branch** (ES modules, no build step: `app.js core.js covers.js dj.js
+  render.js store.js player.js mashup.js ui/*.js`; `index.html` is markup + CSS). It is current with `main` apart
+  from these docs, every module parses, and the Safari harness gives the same results as `main`. Not yet merged:
+  it needs the dev → phone → main pass. It produces the pure pieces a Swift port reads from (covers math, sheet
+  contract, brain, DJ prompts). `docs/v2/REFACTOR-PROMPT.md` was written before we saw the branch and is
+  superseded by it.
 - `tools/harness.sh safari` runs the loop in WebKit via safaridriver on hb-5 (needs `safaridriver --enable`).
 - Player changes go `dev` → phone → `main` (HANDOFF.md).
