1. Engine semantics

• [x] 1.1 Update contact resolution so a surviving entity with both YOU and WIN marks the level won after transformations and destruction.
• [x] 1.2 Preserve SINK then DEFEAT precedence and ensure removed same-entity YOU + WIN entities cannot win.
• [x] 1.3 Confirm settled won, destroyed, controlLost, and later-movement behavior remain deterministic.

2. Engine regression coverage

• [x] 2.1 Add fixtures for same-entity YOU + WIN, distinct-entity YOU + WIN, and proof 03's MIAU IS YOU AND WIN rule.
• [x] 2.2 Add SINK/DEFEAT precedence fixtures, including a same-entity YOU + WIN entity destroyed during contact.
• [x] 2.3 Verify undo and reset restore the pre-win state and that dynamic rule changes still update the winning predicate.
• [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.

3. Browser acceptance

• [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.
• [x] 3.2 Verify the browser shows the same proof 03 win after a rule change, while reset and undo remain available and deterministic.
• [x] 3.3 Run the browser acceptance suite with the existing Workshop/Gift and mod-loading checks, and confirm no new console errors.

4. Verification and handoff

• [x] 4.1 Run the production build and record the focused regression result alongside the current 134 Node and 35 browser checks.
• [x] 4.2 Recheck the active stage integration against the settled won event without changing the stage visual contract.
