Sandworm
A story object for asking what robotic excavation would require before any physical disturbance.
The underground city is the central story engine: a way to think through great filters, deep resilience and capability growth without pretending that tunnels are approved, safe or inevitable.

As plausible sci-fi, the city can ask how storage, utilities, safe refuge, logistics, manufacturing, robotics, thermal systems and research might work under strong review.
A story object for asking what robotic excavation would require before any physical disturbance.
A learning image for material loops, thermal systems and closed-loop design.
A way to ask how people live well, not merely survive, during stress.
A simulation layer for showing assumptions, risks, resource flows and veto points.
OpenBefore deep infrastructure could be more than a story, it would need cultural authority, land and environmental law, engineering feasibility, safety, groundwater review, cost clarity, maintenance, emergency access and community benefit.
