Conduct a deep research study on utopian, experimental and futurist settlement models that can inspire Specus Village without being copied literally.

Context:
Specus Village has a future archaeology frame. We are interested in utopias, experimental communities and futurist settlement visions as cultural and spatial references. We do not want fantasy without operational clarity, but we do want to understand strong myths and spatial ideas.

Research:
Study historical and modern utopian / futurist settlement concepts, including but not limited to:
- Thomas More / utopia as political imagination
- Fourier's phalanstery
- Robert Owen / New Harmony
- Garden City as social utopia
- Broadacre City
- arcology / Paolo Soleri
- Metabolist movement
- Drop City and counterculture communes
- Buckminster Fuller related settlement thinking
- cybernetic / networked city ideas if relevant
- eco-utopias and solarpunk communities
- contemporary speculative villages and off-grid futures

For each:
1. Core myth or promise.
2. Spatial model.
3. Social model.
4. Infrastructure model.
5. Economic model if any.
6. Why people believed in it.
7. Why it failed, stayed theoretical, or partially worked.
8. What symbolic value remains useful.
9. What practical lessons apply to Specus Village.

Important:
Do not treat utopias as direct templates. Treat them as cultural and design references.

Output:
Save / export the result as a Markdown file named:
DR-SV-22_Utopian_And_Futurist_Settlement_Models.md

The Markdown file must include:
- map of utopian settlement archetypes
- strongest useful myths
- operational failures to avoid
- design principles for Specus Village
- content / storytelling references
- sources
- confidence levels
