Coherence-First Craft: Engineering Specification Math-Aligned Design for Capacity-Limited Motion Date: January 18, 2026 Status: Concept Engineering Specification Executive Summary This document specifies a coherence-first craft (CFC) architecture that directly implements the Communication–Coherence Framework (CCF). The craft achieves motion, maneuverability, and sensing evasion through continuous control of coherence-coupling gradients and discrete re-indexing of boundary interaction modes, not through thrust, reaction mass, or mechanical impulse. The design is grounded in finite-time thermodynamics and hybrid control theory, with explicit mapping between mathematical parameters (chi, Phi, C_tot, Delta, sigma, M) and engineered subsystems. All signatures, limits, and constraints follow directly from the CCF model. Part I: System Architecture 1.1 Layered Hull Design The hull is not a load-bearing shell but a coherence boundary. It is the primary control surface where the craft couples to the environment and shapes observer-inferred interaction. Outer Layer: Impedance-Matched Metasurface Purpose: Realize chi(x,t) as a tunable, spatially varying coupling parameter. Implementation: - Multi-band electromagnetic metamaterial skin with tunable permittivity and permeability - Acoustic metamaterial layer with phase and impedance control - Plasma-control coupling for transmedium impedance matching - Dynamically driven structural resonators Middle Layer: Dissipation Router and Entropy Sink Purpose: Maintain flat internal coherence (grad C_int approx 0) by routing entropy outward. Implementation: - Phononic bandgap structures - Lossy metamaterial absorbers - Field-gated dissipation channels - Entropy-prioritized routing Inner Frame: Phase-Stable Reference Purpose: Maintain a uniform internal coherence field serving as inertial reference. Implementation: - Low-expansion composite core - High-Q vibrational isolation - Precision resonant cavities - Internal inertial sensors referenced to C_int 1.2 Coherence Engine The coherence engine regulates total coherence load and boundary coupling rather than producing force. Coherence Reservoir Implementation includes microwave cavity banks, optical resonators, spin ensembles, and mechanical oscillators. C_tot is the sum of stored coherence across modes. C_max is set by isolation and dissipation capacity. Delta(t) = C_max - C_tot(t). Shaping Subsystem Boundary-layer Phi(x,t) = chi(x,t)*C(x,t) gradients are sculpted using phased electromagnetic arrays, acoustic transducers, optical coherence patterns, and plasma field control. Limiting Subsystem Real-time monitoring of Delta enforces mobility collapse near the coherence cliff. Continuous control authority is reduced as Delta approaches zero. 1.3 Hybrid Control Architecture The control system is explicitly hybrid, combining continuous regulation with discrete sigma-mode switching. Part II: Motion Modes and Operational Envelopes Hover Mode: Symmetric chi patterns maintain station-keeping with minimal dissipation. Delta remains high, allowing long-duration hover. Translation Mode: Asymmetric Phi gradients produce observer-inferred acceleration. Internal coherence remains flat; no impulse is generated. Abrupt Reorientation (Right-Angle Turn): Decoupling, internal frame rotation, and recoupling produce apparent instantaneous direction change without mechanical impulse. Transmedium Mode: Continuous impedance matching across media boundaries avoids shock, cavitation, and energy loss. Operations are scheduled when Delta is high. Part III: Control Signatures and Experimental Discriminators Expected Signatures: - Collapse of coherence margin Delta prior to kinematic anomaly - Drop in coupling chi before apparent motion discontinuity - Absence of mechanical impulse - Controlled, distributed thermal dissipation Where Anomalies Should Not Appear: - Systems with abundant coherence margin - Passive or uncontrolled objects - High signal-to-noise tracking environments Part IV: Power and Performance Limits Power consumption is set by coherence maintenance, boundary actuation, thermal rejection, and control electronics. Typical envelope: - Sustained power: 10–100 kW - Transient peaks: up to 10x during high-demand maneuvers Part V: Design Consistency with CCF Mathematics All subsystems map directly to CCF variables: C, C_tot, C_max, Delta, chi, Phi, sigma, and M. The design respects conservation laws, thermodynamics, and hybrid control theory. Conclusion The Coherence-First Craft is a mathematically consistent engineering concept implementing the Communication–Coherence Framework directly in hardware. Apparent anomalous motion arises from boundary-coupling control and hybrid re-indexing, not from thrust or exotic physics. External Morphology and Observable Characteristics (Derived from a Coherence-First Craft Architecture) Overview A craft constructed according to the Coherence-First Craft (CFC) specification presents an external morphology fundamentally different from thrust-based or aerodynamically controlled vehicles. The hull functions as a coherence boundary rather than a load-bearing shell, propulsion interface, or aerodynamic lifting surface. Overall Form The craft adopts a compact, continuously curved geometry—lenticular, ovoid, or lozenge-like—chosen to minimize geometric singularities and avoid concentrating gradients in the coupling field chi(x,t) or observer-coupling potential Phi(x,t). Continuous curvature supports stable, spatially distributed modulation of chi(x,t), enabling uniform control authority and reduced localized dissipation. Protruding structures such as wings, fins, rotors, intakes, or exhaust nozzles are absent. These are unnecessary in a system where motion arises from boundary-coupling gradients rather than momentum exchange, and they introduce impedance discontinuities that complicate coherence isolation and dissipation routing. Outer Skin and Surface Structure The outer hull resembles an active metasurface rather than a conventional vehicle skin. The surface is composed of tiled or tessellated electromagnetic and acoustic metamaterial regions incorporating phased-array elements, resonant patches, and field-coupling structures. Surface detail is subtle and flush-mounted. Visual cues arise primarily from fine-scale patterning associated with EM, acoustic, optical, or plasma-mediated boundary control rather than from mechanical actuation. Surface properties—reflectivity, emissivity, polarization response, or faint optical effects—may change smoothly as chi(x,t) and Phi(x,t) are modulated. Windows, Openings, and Edges Traditional windows or viewports are unlikely. Internal sensing, navigation, and control reference the internal coherence field C_int and external field measurements rather than direct optical viewing. Transparent discontinuities would undermine impedance matching and coherence isolation. Any required openings—docking interfaces, access ports, or landing structures—are concealed behind conformal, sliding, or retractable covers. When closed, these preserve a continuous boundary layer and uniform chi(x,t) control. Edges, seams, and joints are minimized and engineered to remain electromagnetically and acoustically smooth at operational frequencies. Thermal and Dissipation Signatures Thermal management does not rely on localized exhausts, hot plumes, or high-velocity outflows. Entropy produced by boundary interactions and coherence regulation is routed through engineered dissipation pathways embedded within the hull. Externally, this manifests as a broad, distributed thermal signature rather than discrete hot spots. Under nominal operation, thermal contrast with the environment may be minimal. Under higher-demand maneuvers, observers may detect transient, spatially patterned surface brightening corresponding to controlled dissipation routing rather than combustion or plasma exhaust. This produces a soft, diffuse emission regime lacking directional plume structure. Motion and Flight Behavior In hover or station-keeping, the craft appears silent and mechanically inert, with no reaction mass, jet wash, rotor downwash, or aerodynamic control activity. Observable activity is confined to subtle changes in surface patterning or field effects as chi(x,t) is adjusted. During translation, acceleration, or abrupt reorientation, the hull remains rigid and intact. Apparent changes in velocity or direction may be sudden, including right-angle turns or rapid accelerations, without accompanying mechanical impulse signatures. Observable effects are limited to shifts in surface EM, optical, or plasma-related phenomena rather than structural motion or exhaust.
