Golden Age

Every cell below names its exact field, source row, and source column. Cluster alternatives remain alternatives; graphical biosphere distributions remain explicitly not transcribed.

Each row is a categorical source cell. A blank remains “no signature listed by this method”; it does not become an absence-of-technology claim.

Published ellipses remain null. They never silently become numeric zero, and no PDF-digitized spectrum is presented as authoritative raw data.

Pollution, illumination, surface modification, satellite belts, and aerosols use their own source units. The Atlas does not compress them onto a misleading common scale.

System signatures are reported in Table 8. Collapse values below are reported outcomes from an independent published model; they are not a timeline inferred from Table 9.

These creative works are not scientific evidence. Rights-restricted works stay link-only; open-license works remain attributed and are not silently repurposed as scenario textures.
