+# TODO

+## Algorithm 2026-09-01
+
+- [ ] Unused Vite leftovers are gone: `frontend/src/counter.ts` and `frontend/src/assets/{hero.png,typescript.svg,vite.svg}` are deleted and nothing imports them.
+- [ ] Frontend unit-test/screenshot stack is gone: no `vitest` dep or `npm test` script, no `frontend/src/*.test.ts`, no `@playwright/test`, no `frontend/screenshot.cjs`.
+- [ ] Backend `#[cfg(test)]` modules in `backend/src/game.rs` and `backend/src/protocol.rs` are gone.
+- [ ] `e2e/load_test.cjs` is deleted and README no longer lists it.
+- [ ] `POST /room` and `generate_room_code` are removed from `backend/src/main.rs`; rooms are only created via `?room=`.
+- [ ] Baseball scoreboard is gone (`frontend/src/scoreboard.ts`, `#scoreboard-baseball`); HUD keeps stones-left chips and running totals only.
+- [ ] README no longer claims a continuous m/s slider, a local friction scalar, or live `jasonlooked`/`pr2-features` branches; e2e `throwFor` no longer sends `friction`.
+
+## Algorithm 2026-09-03
+
+- [ ] Backend `#[cfg(test)]` module in `backend/src/physics.rs` is gone, and test-only `PhysicsWorld::new_open` is gone with it.
+- [ ] Unused Vite leftover `frontend/public/icons.svg` is deleted; nothing in HTML/CSS/TS references it (favicon.svg stays).
