description: >
  Top-down immersive sim with occlusion-based detection mechanics and
  combat elements. Single-character perspective where asymmetric information
  is the core gameplay mechanic. A Rimworld-style storyteller drives
  emergent narrative across a detective-smuggler dual-lens campaign.

setting: >
  Original science fiction universe — the Settled Reach, a network of
  star systems connected by Founder Gates. Neural lattice technology
  enables soft immortality, forking, and re-embodiment. The v0.1
  vertical slice takes place in Sova Transit District, Van Maanen's Star.

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
