Designed around the boundaries
Many considerations.
One accountable action.
Inspect the architecture and the conditions that must be satisfied before a system acts. These are technical research explorations, not packaged client products.

The technical exploration below describes research-stage architecture and its stated assumptions. It is not a packaged product, a compliance certification, or a promise of production performance. Detailed evidence and protected disclosures are available through an NDA request.

Deterministic Portfolio
Risk Certification
6-channel parallel constraint evaluation for every portfolio trade. Smooth barrier functions with per-instrument calibration. Real-time regime detection. 4-zone deterministic safety classification. Every decision auditable. Every certificate hash-chained.
Six Parallel Constraint Channels
Every proposed trade is evaluated across six independent risk channels simultaneously. Each channel returns a normalized margin in [0,1]. The binding constraint — the minimum margin — drives the final safety classification.
Market Risk
Value-at-Risk (VaR), DV01 duration sensitivity, and FX Delta exposure. Captures directional and rate-driven portfolio risk with deterministic bounds.
Credit Risk
CS01 credit spread sensitivity and spread risk exposure. Evaluates counterparty and issuer credit deterioration impact on portfolio value.
Liquidity Risk
Bid-ask spread analysis and volume constraints. Ensures proposed trades can be executed without excessive market impact or slippage.
Concentration Risk
Herfindahl-Hirschman Index (HHI) and exposure limits. Prevents dangerous concentration in single names, sectors, or geographies.
Regulatory Capital
Basel III Risk-Weighted Assets (RWA) computation. Ensures trades maintain capital adequacy requirements and regulatory compliance at all times.
Factor Risk
PCA-based factor exposure analysis. Decomposes portfolio risk into systematic factors, detecting hidden correlations and unintended factor tilts.
Smooth Barrier Functions
Traditional risk systems use hard cutoffs — a trade is either allowed or blocked. This creates cliff-edge behavior and gaming opportunities. Our smooth barrier approach creates differentiable constraint boundaries that provide early warning signals as positions approach limits.
The barrier function continuously and differentiably approximates the binding constraint margin. As a position approaches a limit, the barrier surface steepens — providing early warning signals and graded response rather than hard cliff edges. No discontinuities, no gaming opportunities.
Each instrument class is calibrated to its own constraint sensitivity profile. Equities, options, fixed income, and derivatives each receive tailored barrier parameters that reflect their distinct risk structures. The system adapts to asset-specific behavior without manual tuning.
Regime Detection
Markets shift between regimes — low volatility, crisis, recovery. A risk system that ignores regime changes is blind to the most dangerous moments. Our structural detection catches breaks in real time and adapts constraint thresholds automatically.
Continuous monitoring of cross-asset correlation structure detects regime shifts in real time — triggering automatic constraint tightening and escalation to human review before losses propagate.
When a regime shift is detected, the system automatically tightens the binding constraint and escalates to human review. The full detection mechanism and escalation logic is available under NDA.
Structural Safety for Financial Markets
Patent C introduces structural safety guarantees for trading systems. Rather than penalizing constraint violations after the fact, the system makes regulatory breaches topologically unreachable — unsafe trade sizes cannot be reached by construction.
The technical architecture, FRTB claim mapping, and full implementation documentation are available under mutual NDA.

Every trade receives a deterministic safety classification based on its binding constraint margin. No probabilistic scores. No ambiguity. Four zones, hard boundaries, auditable outcomes.
Safe
Certified. All constraint margins above threshold. Trade executes automatically with full audit trail.
Caution
Certified with warning. Approaching constraint boundaries. Flagged for review with specific risk channel detail.
Danger
Escalated to human review. Constraint margins critically low. Requires manual override to proceed.
Blocked
Trade rejected. Constraint violation detected. No override possible. Full rejection certificate with specific channel detail.
