Improved the buildings with reusable glazed ridge lanterns, real lightwells into furnished lofts, and better coexistence with neighboring dormers. Added public mounting contracts and fixed a nested-removal bug while preserving provenance and atomic rollback.

Verified:

- **328 tests passed**, including every previous test.
- **220/220 supported inputs validated**.
- Stress: **5 successes, 11 reported incompatibilities**.
- **42 exterior/cutaway views inspected** and **47 schematic pairs verified**.
- Default CLI, deterministic replay and semantic reload passed.

Updated [schematic](/work/generator/workspace/output.litematic) and [structural companion](/work/generator/workspace/output.litematic.structure.json). See the [building preview](/work/generator/workspace/previews/building-lantern/release/lantern-house-2/front.png) and [assessment](/work/generator/workspace/reports/building-lantern/ASSESSMENT.md).

No serious architectural flaw was found. Reference-level quality remains unfinished: regular room bays, heavy framing, sparse interiors and simple landscapes are still visible. Browser execution was not rerun.
