1## Why23Proof 03 can form `MIAU IS YOU AND WIN`, but the engine currently checks victory only when two different entities overlap, so a same entity carrying both properties never wins. This fix restores the intended first-release meaning of `WIN` while making contact-effect precedence explicit and testable.45## What Changes67- Treat a settled entity with both `YOU` and `WIN` as a victory when the turn resolves.8- Preserve the existing precedence for `SINK` and `DEFEAT`: destruction prevents that entity from winning in the same contact resolution.9- Add engine fixtures for same-entity win, separate-entity win, sink/defeat precedence, undo/reset, and proof 03 regression coverage.10- Add browser acceptance for the proof 03 win card and settled move result.1112## Capabilities1314### New Capabilities1516None.1718### Modified Capabilities1920- `rule-engine`: define same-entity `YOU` + `WIN` victory and its contact-effect precedence.2122## Impact2324The change affects `src/engine.js`, engine fixtures, proof 03 browser coverage, and the settled event's `won` result consumed by the existing stage. It does not add vocabulary, change pack formats, or alter the stage scene contract.
