- Tier 1 (plants + buildings): marked as implemented
- Tier 2 (NPC customization): downgraded to low value because NPCs are
randomly spawned and pathed per-session, so players never see the same
NPCs in the same locations
- Tier 4 (vehicles): corrected to account for autonomous vehicle coasting
after exit (m_worldSpeed is never reset), split into Tier 4a (visibility
only) and 4b (coasting position sync), increased effort estimate
- Updated priority order, effort summary, and opinion sections
Add serialization framework using C++ templates and table-driven lookup
to sync plant and building state between players. Includes world snapshot
routing to requesting peer, relay server Docker support, and fixes for
building color sync, ride vehicle visibility, and ARM compilation.
- WebSocket relay server (Cloudflare Worker + Durable Object)
- Remote player character cloning with walk/idle/ride animations
- Vehicle support for remote players
- INI config for relay URL
- Extension hook for world transition ROI management
