The Crucible is organized as a sequence of projects. Each project changes the question while preserving continuity with the world that came before.
Can designed tribes build civilization, and does that civilization persist?
Project 1 establishes the reference world: baseline geography, bottleneck geography, a controlled duel, and climate-severity comparisons. It shows emergence, overshoot, collapse, and agrarian refugia as the recurring baseline pattern.
Is survival intrinsic, opponent-specific, or context-dependent?
Project 2 separates solo viability from competitive displacement through all-LLM solo tests, duels, and triads. It shows that a tribe can survive alone and still die beside the wrong neighbor.
Can intelligence learn from extinction and redesign better founders?
Project 3 gives LLM designers evidence from prior runs and lets them redesign their founding agents. The lineages evolve toward hardiness, low legacy, internal cohesion, and collapse-survival traits.
Can evolved survivors endure the delayed consequences of civilization?
Project 4 adds aerosol demasking, Arctic methane release, nuclear meltdown, and the stacked condition. Survival remains possible, but recovery to high-complexity civilization becomes much harder.
What kind of future remains after collapse?
The Epilogue tests Ares, natural network collapse, 80,000-pulse futures, reservoir calibration, and the final climate-reservoir projection. It distinguishes survival from recovery.
| Stage | What changes | What remains comparable |
|---|---|---|
| Baseline | Geography, tribe count, duel condition, climate severity. | The same world engine, archive logic, and core agent rules. |
| Competition | Fresh all-LLM roster, solo tests, duels, and triads. | Comparable 40,000-pulse world behavior and tribe-level survival measures. |
| Evolution | LLM designers receive evidence and redesign founders; biologic controls remain fixed. | The redesigned generations run through the same Project 3 world conditions. |
| Bombs | Delayed consequences are added: demasking, methane, nuclear, and stacked shocks. | The evolved tribe field and post-collapse survival metrics remain comparable. |
| Epilogue | The horizon moves beyond collapse: Ares, network decay, 80,000 pulses, and reservoirs. | The question stays focused on survival quality, recovery, and post-collapse equilibrium. |
