History: AI-driven alternate-history simulator
Pax Historia-style sim where the LLM is the world engine.
- React 19 + Vite 6 + Tailwind v4 + shadcn/ui frontend
- Express single-port backend (/api + /sse + built client + SPA fallback)
- SQLite (better-sqlite3) persistence, one row per game
- MapLibre choropleth map (OpenFreeMap dark + ISO_A3 regions)
- Defensive turn loop: strip fences, balanced-{} extract, parse, clamp 0-100,
retry-once nudge, generic 'unclear' fallback; never crashes on bad output
- 5 seed presets (wwii-1939, coldwar-1955, modern-2025, no-wwii-1940, aegis-2400)
- LLM client over native fetch w/ injectable transport (mesh-bot pattern);
LLM_STUB=1 deterministic transport for tests/e2e
- Unit (vitest, 19) + deterministic Playwright e2e
- Multi-stage node:22-slim Docker + Traefik (history.dev.kkhost.pl:4321)

The Stellar Concord — a fragile truce brokered after the Collapse of 2361 — binds them together more by mutual interest than by love. Each polity guards its own domain, its own economy, and its own vision of what humanity should become.\n\nEarth's Union holds the ancestral world and its teeming population. The Orbital Ring dominates the cislunar economy and the fold-gate transit lanes. The Red Collective of Mars has turned the desert into a forge and dreams of independence. The Outer Reach commands the ice-moons and the helium-3 that powers everything. The Deep Void, the most remote and the strangest, watches from the outer dark and plays long games. You are the ruler of one of these powers — and the Concord is only as strong as its weakest treaty.",

Neither side can win a direct war without risking mutual annihilation, so the contest is fought everywhere else — in Berlin, in Korea, in the new space race, and in the non-aligned world.\n\nThe superpowers court the nations of the Global South, fund coups and revolutions, and trade in influence as much as in dollars and rubles.

Power now flows as much through chips and data as through armies, and through finance and shipping lanes as through borders.\n\nThe great challenges are shared and political: climate, the balance of economic power, the spread of autonomous weapons, and the struggle for influence across the oceans and the Arctic.

Germany's army is the most battle-hardened force on the continent, but its resources are finite and its flanks exposed. Britain commands the seas but is an island nation. The Soviet Union has a vast army and deep territory but a fragile industrial base. The United States has unmatched economic power but is geographically isolated and politically divided over entry into the war.\n\nYou are the head of one of these nations.
