Build specification

Asset Production#

The global catalog enumerates 130 explicit requirements in data/assets/assets.json; every Scene has a resolved assets.json. No “miscellaneous furniture” or “tropical plants” entries are permitted.

Master package per raster Component#

RGBA color image with true alpha; optional separable shadow; optional emission mask; material regions; orientation/state variants; asset JSON; provenance; validation Record. Neutral authoring rig is warm upper-left key (315°, 42°) and cool 8–14% fill. Scene-specific horizon/light is never baked into a reusable object.

Status#

• Commons images: primary supplied visual evidence, untouched.
• Existing Observatory/Grove/Apiary/Prairie/Keep and specimen sheets: reusable system references.
• Generated Bellwether Island/Pitch/Second Bell: concept references.
• Catalog assets marked reference-required: production art briefs, not shipping masters.

Acceptance requires all hard gates and visual score ≥88/100 in two lighting fixtures.
