K11 Production System Architecture -- Master Plan

_Generated 2026-04-27 via Evo3 (Research -> 6 Divergent Paths -> Compound Synthesis -> Expand + Master Plan)._ _Full evolution output: Desktop/evo-cube-output/k11-production-system-architecture/_ **Three-tier hybrid architecture** combining NSSM services for headless publishers, Task Scheduler for GPU-bound Unity, and Sony's native mocopi PC app for BT sensor management. New LUMM wire format (0x4C554D4D) carries 27-bone skeletal data as a 772-byte fixed datagram on :9702. Rejected alternatives: - Monolith (everything in Unity) -- kills audio latency win, no cross-machine flexibility - Docker -- USB/BT passthrough impossible, massive overkill for 3 Python scripts - MotionMix-centric (K11 as sensor bridge) -- breaks product premise of self-contained hardware - Full microservice (Unity as NSSM service) -- GPU inaccessible from Session 0 | Port | Protocol | Wire Format | Producer | Consumer(s) | |------|----------|-------------|----------|-------------| | 9700 | UDP | LUMD (0x4C554D44, 40B hdr) | pointcloud_pub.py | Unity LumeUdpReceiver, Tailscale mesh | | 9701 | UDP | LUMF (0x4C554D46, 84B fixed) | audio_pub.py | Unity LumeAudioFftReceiver, Tailscale mesh | | 9702 | UDP | LUMM (0x4C554D4D, 772B fixed) | mocopi_bridge.py | Unity LumeMocopiReceiver, MotionMix iOS | | 12351 | UDP | Sony binary (skdf+fram) | Sony mocopi PC app | mocopi_bridge.py (localhost only) | Bone ordering: Sony mocopi IDs 0-26 (root, spine, chest, neck, head, shoulders, arms, hands, legs, feet, toes, fingers).
