VolWeave Constellation is a multi asset selector that treats the currency universe as a living network whose shape changes with market motion. Each pair is observed through a fixed set of nine aspects that describe how it is behaving right now and how it has behaved recently. These aspects include short and medium returns, a volatility reading, a standardized price deviation, a range pressure estimate, a flow proxy, a simple regime tag, a volatility of volatility proxy, and a persistence proxy. The aspects are stored in a compact ring buffer layout designed for speed and predictable memory use.

At regular intervals the strategy builds a similarity picture across all pairs. It does this by measuring how strongly each pair resembles every other pair when all aspects are considered together. The heavy step is the pairwise correlation pass; it can be sent to an OpenCL kernel when a device is available, and it automatically falls back to a full CPU path when OpenCL is missing or fails. This makes the system robust while still benefiting from acceleration when possible.

The similarity picture is converted into a distance picture, and then blended with an exposure distance table that represents structural overlap between instruments. This blend allows the strategy to respect both statistical co movement and shared currency risk. Once distances are ready, the strategy runs a shortest path refinement so that indirect relationships are recognized, not just direct ones. From the refined distances it computes a compactness value for each pair, which acts like a measure of how centrally and cleanly that pair sits inside the current market network. Volatility is recorded alongside this compactness so that noisy conditions can be penalized or controlled.

Scores are then produced for every pair by combining volatility, compactness, and an average coupling term derived from nearby instruments. The score is shaped into a stable range so it can be compared consistently through time. A learning controller sits above this layer and continuously adapts selection pressure. It uses an unsupervised clustering model to label broad regimes, a reinforcement style agent to adjust aggressiveness and how many pairs to keep, and a compact principal component monitor to detect when market structure becomes dominated by one factor or begins rotating rapidly. These signals adjust internal scaling and the number of selected pairs without breaking the core logic.

The final output is a dynamic top list that updates on a schedule, favoring instruments that are structurally coherent, not overly crowded, and appropriate for the current stability of the market network.

// TGr06D_VolAdjuster_v5.cpp - Zorro64 Strategy DLL
// Strategy D v5: Volatility-Adjusted with MX06 OOP + OpenCL + Learning Controller
// Notes:
// - Keeps full CPU fallback.
// - OpenCL is optional: if OpenCL.dll missing / no device / kernel build fails -> CPU path.
// - OpenCL accelerates the heavy correlation matrix step by offloading pairwise correlations.
// - Correlation is computed in float on GPU; results are stored back into fvar corrMatrix.
