Vol.I.C.02 Sensor Framework Specification and Toolbox Architecture

I. Purpose

This document defines the structural sensor framework used within the
Vol.I.C calibration model.

Sensors are objective structural measurements that evaluate systemic
stability conditions. They do not directly impose corrective measures.
Instead, they feed into the composite System Stability Deviation (SSD)
metric, which informs calibration multipliers.

Sensors must be:

• Measurable • Transparent • Publicly documented • Version-controlled •
Aggregation-consistent • Resistant to superficial restructuring or shell
fragmentation

II. Sensor Categories

The Version 1.0 baseline ships with 20 core sensors across five
structural domains. Additional sensors may be added via the Sensor
Toolbox process.

Category A – Concentration Sensors

1.  Net Productive Capital Concentration Index (NPCCI)
2.  Beneficial Ownership Aggregation Score (BOAS)
3.  Cross-Sector Control Overlap Index (CSCOI)
4.  Voting Authority Density Metric (VADM)
5.  Interlocking Governance Participation Index (IGPI)

Category B – Leverage and Amplification Sensors

6.  Leverage-to-Productivity Ratio (LPR)
7.  Collateralized Borrowing Intensity Index (CBII)
8.  Derivative Exposure Sensitivity Score (DESS)
9.  Margin Sensitivity Amplification Metric (MSAM)
10. Concentration Velocity Rate (CVR)

Category C – Enterprise Density Sensors

11. Mid-Scale Enterprise Density Ratio (MEDR)
12. New Firm Formation Elasticity Index (NFFE)
13. Supplier Layer Redundancy Score (SLRS)
14. Regional Capital Circulation Ratio (RCCR)
15. Employee Equity Participation Ratio (EEPR)

Category D – Shock and Stability Sensors

16. Cascade Propagation Velocity Index (CPVI)
17. Supply Routing Compression Metric (SRCM)
18. Fiscal Crowding-Out Ratio (FCOR)
19. Asset Liquidity Stress Indicator (ALSI)
20. Capital Flight Sensitivity Score (CFSS)

III. Sensor Design Requirements

Each sensor must include:

• Formal definition • Measurement formula • Data source specification •
Reporting frequency • Aggregation methodology • Anti-fragmentation rule
set • Weight range constraints • Sunset review interval

Sensors must measure structural influence rather than nominal
classification. Beneficial ownership aggregation rules must prevent
artificial dilution via shell entities, trusts, or nominal subdivision
without control redistribution.

IV. Aggregation Methodology

Sensors produce normalized outputs within a standardized band.

Each sensor contributes to the System Stability Deviation (SSD) score
according to assigned weight parameters.

SSD = Σ (Sensor Output × Sensor Weight)

Sensor weights are adjustable within defined governance limits but must
remain publicly disclosed.

No single sensor may independently trigger systemic recalibration unless
explicitly designated as a critical-risk override metric and ratified
under governance protocol.

V. Calibration Interaction Rules

Sensor outputs influence:

• Stability Class Assignment • Calibration Multiplier (CM) • Buffer
Requirements • Incentive Eligibility Bands • Reporting Intensity

Calibration adjustments are incremental and capped annually unless
multi-sensor correlated risk thresholds are exceeded.

VI. Sensor Toolbox Architecture

The Sensor Toolbox is a structured library of candidate sensors that may
be added, modified, or retired through governance process.

Toolbox additions must:

• Demonstrate measurable systemic relevance • Avoid redundancy with
existing sensors • Include empirical validation modeling • Publish
projected impact simulations • Undergo public review before adoption

Toolbox removals require:

• Impact assessment • Replacement analysis if necessary • Legislative
ratification where applicable

This modular architecture prevents rigid overfitting while maintaining
structural coherence.

VII. Governance and Transparency

All sensor definitions, weights, and formulas must be:

• Publicly available • Independently auditable • Versioned • Archived
historically

Annual recalibration reports must disclose:

• Sensor outputs • Weight assignments • SSD calculation • Calibration
multiplier adjustments • Justification narrative

Transparency is mandatory to preserve legitimacy and prevent model
manipulation claims.

VIII. Version 1.0 Default Sensor Count

Version 1.0 launches with 20 core sensors.

Additional sensors may be integrated through structured amendment. The
target operating range remains between 15 and 25 active sensors to
preserve balance between robustness and interpretability.

IX. Conclusion

The Sensor Framework provides the structural instrumentation layer of
the 4-3-2-1 stabilization model.

Sensors measure systemic conditions. They do not prescribe ideology.

The Toolbox ensures adaptability while preserving integrity.

The next document formalizes Tier Structural Definitions and Capital
Participation Modeling.
