description: >
  Top-down life-sim set in an original science fiction universe. Asymmetric
  information and occlusion-based perception from a single-character
  perspective, with a Rimworld-style storyteller. Systems interactions like
  The Sims, combat and visuals like single-character Rimworld, world
  generation inheriting from Dwarf Fortress and NMS, economy inspired by
  X4/EVE. Every system is interactable but ignorable — the world is alive
  for any given run.

setting: >
  The Settled Reach — a network of star systems connected by Founder Gates.
  Neural lattice technology enables soft immortality, forking, and
  re-embodiment.

development: >
  Built outside-in along the six-phase Development Cascade (D-166): wiki
  content and star map, economics layer, planetary maps and atlas,
  deterministic world generation (active), player control and in-world
  rendering, room-level detail.

architecture:
  client: Godot 4 (GDScript)
  server: Rust with bevy_ecs (simulation server)
  transport: subprocess/IPC via TCP with MessagePack serialization
  protocol: length-prefixed MessagePack frames (4-byte big-endian)
  determinism: ChaCha20 seeded RNG, deterministic tick processing

simulation:
  tick_rate: 10 ticks per game-minute
  time_model: 4 day phases (Morning, Afternoon, Evening, Night)
  grid: dual-scale (0.5m simulation tiles, 1m visual tiles)
  visibility: symmetric shadowcasting + forward/peripheral/blind vision cone
  knowledge: per-entity knowledge graphs with confidence decay

content:
  format: YAML with JSON Schema validation
  structure: campaigns/systems/stations/districts hierarchy
  npcs: 10-axis model (7 essential + 3 supporting) with CombatCapability
  dialogue: tagged line pools with 4-layer relational filtering
  population: 30% flat / 50% mundane triangles / 20% intrigue-entangled
