What This Prescription Does NOT Cover

• Engine design — Shachi is a toolkit, not an engine. Game-specific code (entity systems, scripting, world management) is outside scope.
• WinCE path — The Windows CE Toolkit exists but is a different development paradigm entirely. Shachi targets the native SH-4/KOS path.
• Online multiplayer — DC networking (BBA, modem) exists in KOS. Shachi doesn’t add to it beyond the LLM bridge concept.
• Full Ninja replacement — shachi-anim loads NJA data but doesn’t replicate Ninja’s full 266-function API. It’s a practical subset.
