Canonical source summary
After the peak of high technology, people live by subsistence, simple tools, and artisanal crafts. Rituals and oral traditions reinforce belonging to the biosphere, while settlements migrate with seasonal and planetary cycles.3.2.1 Narrative summaries · row S4 · column Narrative summary · page 11 ↗

What each method lists.
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.

Planetary reach stays multidimensional.
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 evidence + reported trajectory
Different evidence classes.
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.

Reported collapse/recovery outcome
Collapses in every run and has the lowest reported mean duty cycle, with frequent deep collapses.
