System Architecture
Governed quantitative infrastructure for controlled exposure
MSIIA architecture organizes signal generation, exposure control, execution logic, and portfolio governance into a layered institutional framework. Each layer is accountable to the next.
Architecture Layers
Five governed layers from signal to execution
Each layer performs a distinct accountability function. No layer may bypass the constraints set by the layer above it.
01 Core Layer
Regime Classification
The IRDM engine classifies prevailing market structure before any signal influences exposure. Defines the operating context for all downstream decisions.
02 Signal Layer
Signal Consensus
Multiple independent signal families vote before directional conviction is released. No single signal source controls the outcome.
03 Exposure Layer
Exposure Governor
Determines capital release, sizing, and concentration limits. Operates regime-conditionally — tighter constraints in uncertain environments.
04 Execution Layer
Execution Engine
Concentrates order flow into governed review windows. Applies execution cadence discipline and achieves 14–25 bps annual improvement vs benchmark.
05 Audit Layer
Risk & Audit
Non-discretionary enforcement of drawdown caps, portfolio correlation limits, and event gate suppression. All decisions time-stamped and auditable.
Architecture Model
From regime classification to portfolio release
The flow is unidirectional. Each layer must clear its own governance constraints before passing authority to the next.
Classify market structure. Define the operating context for the entire stack.
Multi-signal consensus vote. Directional conviction authorized or suppressed.
Regime-conditional sizing. Capital released, clipped, or deferred here.
Governed execution windows. Cadence discipline, optimised order flow.
Drawdown enforcement, event gate suppression, full audit trail.
Governed capital release. Aggregate constraints verified, execution authorized.
Exposure Map
System exposure categories and governance
Capital is allocated across five functional exposure categories, each with defined risk thresholds and portfolio dependency rules.
Directional
Directional Alpha
Primary systematic alpha source. Regime-gated. Conviction required from signal consensus before release.
Defensive
Defensive Overlay
Tail protection and convexity layer. Activated when regime classification shifts toward disorder. Managed carry cost.
Execution
Execution Control
Order optimisation budget. Governs timing discipline and slippage minimisation across all execution windows.
Recovery
Recovery Logic
Staged capital restoration after drawdown or regime dislocation. Three-phase re-engagement with confirmation gates.
Monitoring
Correlation Monitor
Rolling matrix surveillance across all sleeves. Flags concentration risk and cross-system dependency violations.
Crisis Defense
Crisis Protocol
Last-resort capital defense activated during systemic stress. Three-stage escalation with automatic regime-driven triggers.
Portfolio Analytics
Exposure, risk contribution, and regime transitions
Exposure Distribution
Capital allocation by category
Risk Contribution
Risk budget utilisation per sleeve
Regime State Transitions
Trending / Defensive / Neutral states over time
Governance Checkpoints
Six mandatory reviews before any capital is deployed
Each checkpoint is non-discretionary. Failure at any point halts the deployment pathway.
Capital Threshold Review
Portfolio-level capital thresholds verified against current drawdown, regime state, and volatility budget before any release is approved.
Risk Constraint Verification
All VaR, drawdown cap, and correlation limits verified at sleeve and aggregate level. Violations block deployment automatically.
Deployment Approval
Formal signal authorization required from the consensus layer before execution authority is granted to the Execution Engine.
Audit Trail Logging
All decisions, signals, and state transitions are time-stamped and logged. The full decision pathway is reconstructable at any point.
Portfolio Conflict Detection
Cross-system dependency matrix checked for concentration, correlation, and mandate conflicts before any new exposure is admitted.
Access Control
Platform access requires formal qualification. System parameters and model specifications are available only to reviewed and approved allocators.
Technical Specification
Infrastructure parameters and deployment mode
Architecture Review
Engage through a structured access conversation
Architecture detail, deployment pathways, and product fit are discussed through review-led access conversations — not open distribution. Formal qualification required.
