1## 1. Engine semantics23- [x] 1.1 Update contact resolution so a surviving entity with both `YOU` and `WIN` marks the level won after transformations and destruction.4- [x] 1.2 Preserve `SINK` then `DEFEAT` precedence and ensure removed same-entity `YOU` + `WIN` entities cannot win.5- [x] 1.3 Confirm settled `won`, `destroyed`, `controlLost`, and later-movement behavior remain deterministic.67## 2. Engine regression coverage89- [x] 2.1 Add fixtures for same-entity `YOU` + `WIN`, distinct-entity `YOU` + `WIN`, and proof 03's `MIAU IS YOU AND WIN` rule.10- [x] 2.2 Add SINK/DEFEAT precedence fixtures, including a same-entity `YOU` + `WIN` entity destroyed during contact.11- [x] 2.3 Verify undo and reset restore the pre-win state and that dynamic rule changes still update the winning predicate.12- [x] 2.4 Run the full Node suite with the bundled CommonJS mods loaded and confirm existing rule changes, mod loading, and settled events remain green.1314## 3. Browser acceptance1516- [x] 3.1 Play proof 03 through the verified keyboard path and verify the settled win event opens the existing Win scene; retain shared touch/gamepad coverage in the browser suite.17- [x] 3.2 Verify the browser shows the same proof 03 win after a rule change, while reset and undo remain available and deterministic.18- [x] 3.3 Run the browser acceptance suite with the existing Workshop/Gift and mod-loading checks, and confirm no new console errors.1920## 4. Verification and handoff2122- [x] 4.1 Run the production build and record the focused regression result alongside the current 134 Node and 35 browser checks.23- [x] 4.2 Recheck the active stage integration against the settled `won` event without changing the stage visual contract.
