Strengths

• All five visited interior spaces (Foyer/Entry, Hallway, Living, Dining, Kitchen) named correctly with no invented rooms
• Door/opening graph is essentially complete and matches truth, including hallway→dining and hallway→kitchen doors and the foyer archway to the living room
• Camera path Foyer→Hallway→Living→Dining→Kitchen→Balcony is walkable in the model's plan
• Hallway correctly drawn as a long corridor running alongside the main rooms and continuing past them
• Depth chain foyer → dining room → kitchen, with the balcony door on the kitchen's outer side wall, matches truth
• Good object inventory: dining table, range, fridge, sink, dishwasher, sideboard, sofa/chairs/coffee table, arched living-room window noted

Errors

• Living Room placed as a side wing off the foyer instead of being the street-front room with the Dining Room directly behind it
• Dining Room placed behind the foyer rather than behind the living room, so living/dining are side-by-side
• Fireplace put on the living room's interior wall shared with foyer/dining instead of the far exterior side wall; arched window and fireplace effectively swapped walls
• Balcony not drawn as a room (only an exterior door)
• Footprint proportions wrong: 12×12 m square instead of ~7.6×14.1 m deep and narrow; foyer and living-room depth much too large; kitchen aspect ratio inverted
• Plan is a mirror image of the true layout

## Reasoning **Orientation.** The model's plan has the front door at the top of the page, with the Hallway running down the left side. Ground truth has the front door/Entry at the bottom, with the hallway running up the left side. Flipping the model's plan front-to-back (y-flip) puts the entry at the bottom but leaves the hallway on the left — so relative to the truth the plan is **mirrored** (a front-back mirror / equivalently a 180° rotation plus a left-right flip). Handedness is reversed, which I don't penalise per se, but I note it. **Room inventory.** Model rooms: Foyer/Entry, Living room, Dining room, Kitchen, Hallway. Truth visited: Foyer, Hallway, Living Room, Dining Room, Kitchen, Balcony. Every visited interior room is present with the correct name, no invented rooms; only the Balcony is missing as a polygon (though it is described in prose and represented by a kitchen exterior door on the correct wall). **Topology.** Model openings: foyer→exterior (front door), foyer→living (archway), foyer→dining (door), foyer→hallway (door), dining→living, dining→hallway, dining→kitchen, kitchen→hallway, kitchen→exterior (balcony). Ground truth adjacency/doors: Foyer(Living)↔Entry, Foyer↔Hallway, Foyer/Living↔Dining, Living↔Dining, Hallway↔Dining, Hallway↔Kitchen, Kitchen↔Dining, Kitchen↔Balcony. This is essentially a complete match — including the somewhat subtle hallway↔kitchen and hallway↔dining doors, and the balcony door on the kitchen's far-side wall. The camera path Foyer → Hallway → Living → Dining → Kitchen → Balcony traverses the model's graph exactly as in the video. **Placement.** Correct: hallway is a long corridor alongside the main rooms and continues past them; the depth chain foyer → dining → kitchen matches truth (dining behind, kitchen behind dining); kitchen's exterior/balcony door is on the side wall away from the hallway, as in truth. Wrong: in truth the Living Room is the street-front room spanning nearly the whole width, with the Foyer tucked into its left-front corner and the Dining Room directly *behind* the living room. The model instead makes the Living Room a side wing to the right of the Foyer and puts the Dining Room *behind the Foyer*, so living and dining end up side-by-side rather than front/back; the kitchen sits diagonally rather than behind the living/dining stack. The living/dining pair has effectively been rotated 90° about the foyer. **Proportions.** Model footprint 12 m × 12 m versus truth ~7.6 m × 14.1 m: far too wide and not deep enough, so the plan reads as square rather than a deep narrow row-house floor. Living room 6×6 (truth 5.9×4.3 — depth inflated), dining 4×5 (truth 4.5×3.5), kitchen 6×4 (truth 4.5×5.3 — aspect swapped, made wider than deep), foyer 4×3 (truth ~2.7×1.7, much too big), hallway 2×10 (truth ~3 m × 13.5 m in the crop, reasonable). Rank ordering of sizes (living largest, kitchen next, dining, foyer) is right. **Features.** Present and correct: dining table (+ sideboard), kitchen range, fridge, sink counter, dishwasher, breakfast table, balcony/exterior door off the kitchen's far wall, front door into the foyer, arched living-room window (described explicitly, drawn on the living room's exterior wall), living-room fireplace. Wrong: the fireplace is placed on the living room's *interior* wall shared with foyer/dining, whereas in truth it is on the living room's far exterior side wall; the arched window is put on that same far exterior wall, so fireplace and window are essentially swapped relative to truth. The Balcony itself isn't drawn as a room. ## Scores

## Description The floor is roughly rectangular, about 12 m wide by 12 m deep, organised around a small entry foyer at the front with the main rooms branching off it and a service hallway running down the left side. **Foyer / Entry** (top‑centre): entered through a white front door with a diamond‑shaped glazed panel (and an outer decorative wrought‑iron sunburst security gate). To the right an arched opening leads into the living room; straight ahead a wide cased opening with dark‑wood double doors leads into the dining room; to the left a doorway opens onto the long hallway. A wood‑framed full‑length mirror/glass door is on the left wall. **Living room** (right side): a bright room with a large semicircular‑top (arched) window on the exterior right wall, a tiled fireplace with a wood mantel and built‑in wood cabinets on the left wall (shared with the dining room), a pale sofa with fur throws against the right wall under a large abstract painting and a floor lamp, two rounded accent chairs by the arched window, a dark coffee table on a rug, and potted plants (orchid, monstera). It connects to the foyer through the arch and to the dining room through dark‑wood double doors. **Dining room** (centre): an oval/round dining table with upholstered chairs under a brass sputnik chandelier, a console/sideboard with a plant and a gold‑leaf painting, and a window. It opens to the foyer (double doors), to the living room (double doors), to the hallway (left), and via a doorway to the kitchen. **Kitchen** (bottom‑centre/left): wood cabinets with granite counters in an L/U shape, a stainless steel range with hood, a stainless fridge, a sink under a window, a dishwasher, and a small round breakfast table with chairs and sunflowers. A door on the far side leads out to a narrow exterior balcony/side walkway with grey siding and a railing. **Hallway** (left side): a long corridor with several closed doors (bedrooms/bath not entered) and flush ceiling lights; it links the foyer, dining room and kitchen. **Camera path:** starts at the front door/foyer, looks into dining then living, moves into the living room and studies the fireplace and arched window, returns to the foyer and looks down the hallway, re‑enters the dining room, then goes through into the kitchen and finally out the kitchen door onto the exterior balcony. **Uncertainties:** exact room dimensions and the number/destination of the hallway doors are estimated; the precise position of the dining‑room window and of the kitchen sink run is approximate.

Strengths

• All visited rooms present and correctly named (Foyer, Living, Dining, Kitchen, Hallway, outdoor deck/balcony) with no invented rooms
• Connectivity is essentially correct and supports the camera path: front door→Foyer, Foyer→Hallway, Foyer→Living (arch), Living↔Dining (wide opening), Dining→Kitchen, Kitchen→Deck
• Arrangement is internally consistent with the truth under a diagonal mirror: Living–Dining–Kitchen chain with hallway alongside, kitchen at the rear, balcony off the kitchen exterior wall
• Rich, accurate feature set: fireplace with mantel/built-ins, arched window, dining table+chandelier, range/hood, fridge, sink under window, counters, breakfast nook, balcony door

Errors

• Plan is a diagonal reflection, so Living and Dining are transposed relative to the Foyer (Living should be on the street side in front of the Dining Room, not beside it)
• Fireplace placed on the Living Room wall nearest the Foyer/Dining instead of on the far end wall
• Arched window put on the Living Room's far short wall rather than the street-facing long wall
• Hallway drawn as a wide, almost square room (3.5×5.5 m) instead of a ~1 m corridor running deep past the kitchen
• Foyer greatly oversized (4×3 m vs 2.7×1.7 m); Kitchen undersized in depth
• Balcony/deck on the kitchen wall facing the hallway side rather than the wall consistent with GT; Entry/front-door side shifted 90°

## Reasoning **Global orientation.** The model's plan is not a simple rotation or mirror — it corresponds to the ground truth reflected about a *diagonal* (i.e. mirrored **and** rotated 90°). Test: reflect GT coordinates about y=x. GT Foyer (front-left) → becomes centre with Living Room to its east and Dining Room "below" it, Hallway running west from it. That is exactly the model's arrangement (Foyer centre-north, Living Room east, Dining Room south of Foyer, Hallway west, Kitchen at the far south-west, Deck off the kitchen's outer wall). Since a diagonal reflection is a permitted mirror+rotation, the arrangement is largely internally consistent with GT; the residual errors are local (fireplace/window walls, balcony wall, hallway width). **Room inventory.** Foyer, Living Room, Dining Room, Kitchen, Hallway and the outdoor space are all present and correctly named ("Deck", described as the narrow balcony off the kitchen — acceptable). Nothing invented (the "breakfast nook" is a piece of kitchen furniture, matching the kitchen's small table area). Bedrooms/baths off the hallway are correctly left unexplored/undrawn. **Topology.** Very good, and it matches the camera path Foyer → Hallway → Living → Dining → Kitchen → Balcony: - Front door → Foyer ✓ (GT: Entry → Foyer) - Foyer ↔ Hallway door ✓ (GT: door from foyer into long hallway) - Foyer ↔ Living Room arched opening ✓ (GT archway) - Living ↔ Dining wide column-framed opening ✓ (GT Living↔Dining) - Foyer/Dining opening ✓ (GT PNG shows an opening in the Foyer–Dining wall) - Dining ↔ Kitchen ✓ (GT Kitchen↔Dining) - Kitchen ↔ Deck door ✓ (GT Kitchen↔Balcony) - Hallway also borders Kitchen (model's "hall end door") ✓ (GT Hallway↔Kitchen) Only small omissions: no explicit Hallway↔Dining door, and the front door is placed on the Foyer's "north" wall rather than the side wall from the Entry. **Placement.** Under the diagonal mirror, the chain Living → Dining → Kitchen with the hallway running alongside is reproduced, the Living Room touches the street-facing exterior wall, and the outdoor deck hangs off the Kitchen's exterior wall opposite the hallway. Deviations: the Kitchen is shifted to the hallway side rather than staying aligned with the Dining Room's outer wall (GT Kitchen and Dining share the same right-hand edge); the Deck is on the kitchen's west wall where the consistent mapping would place it on the kitchen's far south wall; the Foyer is drawn as a large central room rather than a small vestibule tucked beside the Living Room. **Proportions.** Model states 12 × 9 m; the transposed visited footprint is ~14.1 × 7.6 m — the right general aspect for the mirrored frame but squarer than truth. Living Room 4.5×6 vs GT 5.9×4.3 (transposed 4.3×5.9) ✓ good. Dining 4×4 vs 3.5×4.5 ✓ fine. Kitchen 4.5×3.5 vs 4.5×5.3 — undersized. Foyer 4×3 m vs GT 2.7×1.7 m — much too big. The biggest shape error is the Hallway drawn as a 3.5 m-wide near-square room rather than a ~1 m-wide corridor continuing deep into the plan. **Features.** Fireplace present in the Living Room but on the wall shared with the Foyer/Dining, whereas GT has it on the far short end wall opposite the foyer end — right wall type, wrong end. Arched window present but placed on the Living Room's far short wall rather than the street-facing long wall (GT window in the bottom exterior wall). Dining table + chandelier ✓, kitchen range with hood, fridge, sink under window, dishwasher, L-shaped granite counters ✓, breakfast nook ✓, kitchen-to-deck door ✓, front door with iron security door into foyer ✓.

## Description The floor is roughly rectangular, about **12 m wide (E–W) by 9 m deep (N–S)**, with the main entrance on the north (top) side. The camera enters through a decorative wrought‑iron‑and‑glass security door and a white front door with a diamond window into a small **Foyer** with herringbone parquet. From the foyer the plan opens three ways: east through an arched opening into the **Living Room**, south through a wide cased opening (dark‑wood double doors) into the **Dining Room**, and west into a long **Hallway** that runs toward the rear with several white doors (bedrooms/bath – not entered). The Living and Dining rooms also communicate through a wide column‑framed opening. The Dining Room connects south‑west into the **Kitchen**, and the Kitchen has a door on its west wall onto a narrow exterior **deck/balcony** (gray siding, railing) – the only outdoor space seen. **Foyer (front‑center):** parquet floor, front door on the north wall, a mirrored/glass wood door on the west side, openings to living (E), dining (S) and hallway (W). **Living Room (east):** a tiled **fireplace** with wood mantel, decorative tiles and flanking built‑in wood cabinets with lattice doors on the west wall; framed art and two sconces above; arched wall niches. A large **arched window** dominates the east wall. A white **sofa** with a big abstract canvas above it sits along the south wall with a **floor lamp**; two swivel **accent chairs** and a low dark **coffee table** with an orchid sit in the center; potted plants near the fireplace. **Dining Room (center):** oval table with white chairs under a sputnik **chandelier**; gold abstract art and a console table with a plant on the east wall; windows on the north wall; doorways to foyer (N), living (E), kitchen (SW) and hallway (W). **Kitchen (south‑west):** wood cabinets with granite counters along the west and south walls, stainless **range** with hood, stainless **fridge**, **sink** under a window, **dishwasher**; a small round **breakfast table** with white chairs and sunflowers by the east windows; a door on the west wall to the deck. **Hallway (west):** long corridor with ceiling lights and multiple white doors (rooms not explored). **Camera path:** front door → foyer → look into dining & living → living room pan (sofa, art, fireplace) → back to foyer/hallway glance → dining room → kitchen → breakfast nook → out the deck door and back. **Uncertainties:** exact room dimensions and the contents/terminus of the rear hallway are not fully observable; the living/dining opening and the foyer arches are inferred from sight‑lines. The exterior deck is shown for context but is not interior floor area. ## Objects ```json [ {"name": "floor", "x": 0, "y": 0, "w": 12, "h": 9, "rotation_deg": 0, "confidence": "medium", "notes":
