Conduit VStar: A Fixed-Width Binary Delta Protocol for Continuous Multi-Dimensional Sensor Streaming on Constrained Environments

Prior art disclosure for a fixed-width 13-byte binary token protocol encoding multi-dimensional sensor streams via delta compression. Designed for constrained environments (Android IME, IoT, edge devices) where variable-length formats fail due to buffering requirements and partial recovery guarantees. Original contributions: (1) fixed-width token as architectural robustness constraint enabling O(1) parsing and unbuffered point-by-point disk writes; (2) dual position signal via inverse rank fields (sr/pr) for autoregressive model consumption; (3) signed extension dimension (h) for ornament offset and Z-axis reservation; (4) dynamic scale parameter (vstar_unit) for device-independent normalization; (5) post-inference semantic boundary token (PS_GROUP_SEP). Reference implementation: Miroir IME (Android InputMethodService, stylus handwriting, Boox Note Air 5C, 284 Hz). Generalization scope: haptic gloves, biometric streams, IoT edge sensors, 3D stylus input, sequential state transport in LLM multi-agent architectures.
