'''Corpus Vis Iuris''' (CVI), Latin for "Body of Legal Force," is the data ingestion, processing, and validation protocol that provides the quantified, empirical foundation for the [[Legal Maneuverability Framework]]. Its function is to systematically scrape, parse, and structure the vast, unstructured data of the legal world into the specific, machine-readable variables required to calculate the [[Positional Maneuverability Score (Lex)|PM]] and [[Strategic Maneuverability Score (Lex)|SM]] scores.}}
{{AetherOS_Component}}
{{Project Status|Beta (v2.1 - Self-Correcting Pipeline)}}
'''Corpus Vis Iuris''' (CVI) is the computational engine and data pipeline serving as the '''adaptive memory''' for the [[Legal Maneuverability Framework]]. It transforms unstructured law into a structured knowledge graph, acting as a high-frequency digital twin of the legal landscape. Its mandate is to enable recursive improvement of the [[Positional Maneuverability Score (Lex)|PM]] and [[Strategic Maneuverability Score (Lex)|SM]] equations through agent-driven feedback, targeting >90% predictive accuracy and >5% quarterly refinement.


== Core Principles ==
== Core Philosophy: The Adaptive Memory ==
The CVI protocol is governed by a set of core principles to ensure the resulting data is robust, reliable, and suitable for rigorous machine learning applications.
CVI tackles the high-entropy, interpretive nature of legal data by functioning as a self-correcting system that co-evolves with the [[Legal Maneuverability Framework]]. It serves as the empirical foundation for [[Lex (AetherOS)|Lex]] agents, particularly [[Lord John Marbury (AetherOS)|Lord John Marbury]], driving the [[Sagas (AetherOS)|SAGA Learning Loop]] to refine equations (e.g., shifting PM to additive forms) and variables (e.g., adding “Regulatory Clarity”). By leveraging active learning and anomaly detection, CVI ensures data legibility adapts to legal shifts, mitigating brittleness such as PACER latency (24-48 hour delays) and NLP errors (15-30% recall drops in complex texts).
* '''Verifiability:''' All data must originate from publicly available or credential-accessible primary sources (e.g., court dockets, statutes).
* '''High-Frequency:''' The system must be capable of updating its datasets in near real-time to reflect new filings, rulings, and precedents.
* '''Granularity:''' Data must be captured at the most granular level possible (e.g., individual docket entries, specific case citations) before being aggregated into higher-level metrics.
* '''Structural Linkage:''' The protocol must build a relational graph between entities (judges, lawyers, litigants, cases, statutes) to enable complex network analysis.


== Data Sourcing and Variable Engineering Pipeline ==
== System Architecture with Self-Correction Loop v2.1 ==
The CVI pipeline is a multi-stage process that transforms raw legal information into the engineered variables used in the scoring equations.
CVI’s five-layer pipeline, enhanced with a Meta-Layer for autonomous adaptation, integrates with AetherOS components.

== SAGA Integration: Evolving the Framework ==
CVI drives recursive improvement of the LM Framework through the SAGA Loop:
# '''Framework Validation''': Historical CVI data (1,000+ cases) serves as a hold-out set to test equation patches (e.g., PM v2.0 additive vs. v1.0 fractional).
# '''Equation Patches''': [[Lord John Marbury (AetherOS)|Marbury]] generates `SUGGERO` commands (e.g., <code>SUGGERO --model PM_Score --action ADD_VARIABLE --variable AIPrecedentScore --weight 0.1 --reason NovelTechCases</code>) based on prediction errors.
# '''Simulated Rollouts''': Patches tested in a sandbox (500-case subset), requiring >5% F1-score lift without degrading other metrics (e.g., via elastic weight consolidation to prevent catastrophic forgetting).
# '''Deployment''': [[Lex (AetherOS)|Praetor]] deploys validated patches to Lexicon templates, updating canonical equations (e.g., non-linear O_s^1.2 in SM).
'''Example''': If SM underpredicts high-friction courts, SAGA proposes a “Crisis Factor” for C_d, validated on PACER subsets, improving accuracy by 8%.
== Governance ==
The [[Collegium (AetherOS)|Collegium]] oversees CVI, with [[Collegium (AetherOS)|Custos Structurae]] (ARC) automating 80% of decisions (e.g., routine patches) and [[Collegium (AetherOS)|Custos Animae]] (human) vetoing ethical changes (e.g., ideology-related patches). Sandbox-First Mandate ensures A/B testing; Praetor’s Gateway deploys validated updates.


== Model Validation & Veracity Testing ==
== Model Validation & Veracity Testing ==
The CVI protocol includes a mandatory validation framework to test the virtue and veracity of both the variables themselves and the models they feed.
Employs ML best practices: 90%+ extraction precision, >85% score accuracy on 1,000-case hold-out set. Adaptation rate: >5% quarterly lift in PM/SM F1-scores, benchmarked against Westlaw AI and Pre/Dicta (88% accuracy on 500 motions). Bias mitigation via fairness audits (e.g., demographic parity, <5% disparity).
 
== Weaknesses ==
- '''Digital Twin Fragility''': Law’s interpretive fluidity undermines fidelity; incomplete data (e.g., 20% sealed cases) distorts adaptations, risking outdated models.
- '''NLP Error Propagation''': 15-30% recall drops in complex texts amplify biases in recursive loops, per legal NLP critiques.
- '''Governance Bottlenecks''': Human vetoes slow recursion in volatile fields (e.g., post-Dobbs shifts), hindering rapid updates.
- '''Ethical Risks''': Scraping raises privacy concerns (e.g., GDPR risks); ideology scores politicize judiciary, requiring continuous debiasing.


# '''Training/Validation Data Split:''' Historical case data is partitioned into an 80% training set and a 20% validation set to prevent overfitting and test the model's ability to generalize to unseen data.
== Brittle Data Modeling Areas ==
# '''Feature Importance Analysis:''' Following model training, statistical analysis (e.g., SHAP values, permutation importance) is used to rank the predictive power of each engineered variable. This identifies which factors are most influential in determining legal outcomes.
- '''Extraction Errors''': NLP brittle to archaic/ambiguous texts (25% error in historical statutes), skewing variable engineering.
# '''Ablation Studies:''' The models are systematically re-trained with specific variables or sub-variables removed. The resulting degradation (or lack thereof) in predictive accuracy is measured to determine the necessity and virtue of each component in the framework. A variable whose removal significantly harms performance is considered critical and virtuous.
- '''Data Scarcity''': Novel domains (e.g., AI law, <100 cases) inflate patch variance (>20%).
- '''Latency Issues''': PACER delays (24-48 hours) erode real-time updates, brittle during rapid rulings.
- '''Bias Amplification''': Self-loops perpetuate underrepresentation without fairness checks.
