Two unit-test groups had drifted from intentional implementation changes
and have been failing CI on main since before they were noticed:
- registry: re-registering a node kind is now HMR-aware — it warns and
replaces in dev/test and only throws in production (registry._register,
introduced in the in-world-selection work). `bun test` runs with
NODE_ENV=test, so the duplicate-kind tests took the dev (warn) path and
no longer threw. Pin NODE_ENV to 'production' for the throw-path
assertions via an `inProduction` helper, and add explicit dev/HMR
coverage for the warn-and-replace path.
- stair-opening-sync: the straight-flight opening geometry was
deliberately enlarged ("increase stair opening buffer constraints",
treadDepth*10 / length*0.8 / 3.0, openingOffset default 0.15). The
enlarged opening now spans nearly the full slab depth, so the manual
hole fixtures (which must *contain* the auto opening to suppress it) no
longer covered it. Enlarge the manual-opening fixtures to genuinely
cover the current opening, preserving each test's intent.
No production code changed — only test fixtures/assertions.

const wall = WallNode.parse({
points: [[0, 0], [5, 0]],
height: 3,
thickness: 0.2,
})
useScene.getState().createNode(wall, parentLevelId)
// Subscribe to scene changes
function MyComponent() {
const nodes = useScene((state) => state.nodes)
const walls = Object.values(nodes).filter(n => n.type === 'wall')
return <div>Total walls: {walls.length}</div>
}
