Human Temporal Interface Layer (HTIL): Phase-Coordination for Human-AI-Quantum Systems

Human Temporal Interface Layer (HTIL) v1.2 is a human-facing interface and procedure layer for systems that coordinate actions using phase windows on a shared cyclic phase variable ϕ(t)∈[0,1)≅S1ϕ(t)∈[0,1)≅S1, with an explicit cycle index n(t)n(t). HTIL is designed for triadic Human–AI–Quantum coordination: humans select/approve phase windows, AI proposes/optimizes them under constraints, and quantum/hardware systems execute within agreed windows. HTIL provides multiple human-readable representations of the same phase point (normalized phase, HS° degrees, and a 12-segment HS index), defines wrap-around-safe window handling using circular distance on the circle, specifies a triadic window-intersection procedure, and introduces monitoring metrics for phase dispersion and overlap fidelity with safe edge-case handling. HTIL is a control-plane / UI layer. It does not introduce a quantum time operator and does not modify the Hilbert space. Security and synchronization guarantees are provided by external protocol layers (e.g., bootstrapping, authenticated messaging); HTIL focuses on representation, decision procedures, and interoperability. Previous version: HTIL v1.0 (Zenodo: 10.5281/zenodo.18003033)This release: v1.2 is an alignment release to match the series-wide canonical conventions and Q-Address-style coordination.
