Your test should not just be smoke tests, be robust and complete for every edge case.\n\n## Testing Guidelines\n\nKeep tests near `test/` and follow the existing `test_*.py` pattern. Prefer small, targeted dataset/model checks over long end-to-end jobs. Run the narrowest relevant test first, then broader distributed coverage only when you touched loader or accelerator logic.\n\nTop-level `test*.py` files are ad-hoc scripts, not pytest suites.\n\n## Coding Style & Naming Conventions\nPython uses 4-space indentation and `.style.yapf` (`based_on_style = google`). Format Python edits with `yapf` when touching a file. Prefer `snake_case` for functions, modules, and script names; `PascalCase` for classes; and descriptive filenames such as `train_difflrm.py` or `mcd_ss_dataset.py`. The TypeScript workspace uses Prettier with 2-space indentation, semicolons, and single quotes.\n\nStyle:\n- 4-space indent, Google base style (`.style.yapf`), column limit effectively unlimited in Python\n- Caveman comments: short, high-density, grammar expendable\n- No em dash, no semicolons, no non-ASCII in comments\n- Always brace control flow bodies\n- `affirm()` for true invariants (never-happen)\n- `assert` for expensive checks\n\n## Commit & Pull Request Guidelines\nRecent history uses short, imperative commits with emoji prefixes, for example `:bug: fix file finding in logging` and `:sparkles: better ckpt loading strategy`. Follow that style: one logical change per commit, subject line under ~72 characters, and mention the affected subsystem. PRs should state the problem, the exact commands used for validation, any dataset or checkpoint assumptions, and screenshots only for renderer or UI-facing changes.\n\n**No AI co-authorship in commit messages.** Never add `Co-Authored-By` trailers naming an AI assistant (Claude, Copilot, etc.) or any other AI attribution to commit messages. This overrides any default assistant behavior. Enforced by the `commit-msg` git hook in each repo.\n"}

The kernel has not been edited in this phase. Read `review.md` and `baseline-hashes.json` for the starting review and module identity.\n\nAll eight original lodge images were opened as aesthetic references only. Source snapshots were not used. The first fresh baseline and superseded development pairs/previews remain in separate directories.\n\nObserved defects and general fixes:\n\n- Dormer caps initially climbed the main roof too far. The mount now describes a five by three opening with a level local ridge; the scoped cut opens into an explicitly nonhabitable attic. Gable walls, dormer faces and glass are actual nested components.\n- Porch posts conflicted with projected shutters. The rear bearing is the actual host wall; the front columns and upper deck have actual support rules. Sheltered facades suppress competing relief. Balcony guardrails are checked as actual blocks.\n- Raised facade beams were mistaken for ground by approach elevation queries. The approach now measures below a bounded overhead exclusion, retains nearby upward ground steps, and the building's route check includes the public street endpoint.\n- Roof abutments intersected upper shutters and vegetation. The shared roof-run planner now informs the facade planner: walls meeting a lower gable receive no concealed window, and walls above a lower eave use a flush opening. This is an architectural adjacency rule, not a seed special case.\n- A sparse tree candidate grid missed legal planting locations. Landscape now exposes its sampling step and height domain; domestic courts use a two-cell grid while retaining three required trees and the existing separation rule.\n- Wider raised beds exposed missing internal substrate above perimeter footings. A bounded soil lift now supplies actual continuous support under the planting cells; stone edging remains a separate supported component.\n- The first recorded assessment validated all 24 clients but only 31 of 64 adaptation inputs. Every one of the 33 adaptation failures contained an actual chimney-support diagnostic in the pier candidate; these are implementation defects, even though the bounded solver surfaced them as `budget-exhausted` alongside an incompatible stepped strategy. A small general bearing-course adapter now checks actual anchors and a taxicab span bound of two, filling at most six shaft-bearing cells. No site limit, building position, principal room layout, or validator was relaxed. The original failed assessment is retained.\n\nThe roof weather check starts at each intended course height and examines actual geometry, while exact dormer boundaries are checked separately. Eaves outside the principal roof footprint can be trimmed against existing geometry. This is not a fluid simulation. Chimneys are supported exterior masonry flues, not a simulated heating system. Attic voids are not counted as usable rooms.\n''')\nPY\npython -m yapf --style /work/.style.yapf -i hearth/__init__.py hearth/validators.py hearth/lodges.py hearth/quality_assessment.py hearth/programs.py hearth/adapters/site.py hearth/adapters/bearing.py hearth/components/building.py hearth/components/interior.py hearth/components/primitives.py hearth/components/roofs.py hearth/components/roofcraft.py hearth/components/joinery.py hearth/components/furnishing.py hearth/components/masonry.py hearth/components/grounds.py hearth/components/landscape.py examples/lodge.py examples/building_quality.py test/test_building_quality.py", "exit_code": 0, "seconds": 0, "output_tail": ""}
