ArcXA SCP provides the structured semantic context (the "map and rules"), while Granite 4.2 acts as the agentic reasoning engine (the "execution brain").
The Grounding Graph (SPO Triples):ArcXA SCP parses raw enterprise schemas, pipeline logs, and compliance policies (from tools like Collibra or Snowflake) into an RDF Knowledge Graph built on SPO triples (e.g., [Customer Data] ---> [hasPrivacyClassification] ---> [HIPAA Restricted]).
The Agentic Reasoning Engine (Granite 4.2):Granite 4.2 queries the ArcXA RDF graph using SPARQL tool calls.It utilizes its native reasoning mode to analyze context, predict mapping failures, or plan multi-step migration tasks before touching production data.
The Governance Loop:Before executing any data transformation, Granite 4.2 evaluates its actions against active logical constraints stored in ArcXA’s SPO graph.
Step-by-Step Workflow
Ingest & Graphify:ArcXA registers source/target systems and maps metadata into atomic SPO triples.
Context Retrieval:Granite 4.2 receives a natural language task (e.g., "Map legacy DB2 columns to target Snowflake schema and mask PII") and queries ArcXA’s Knowledge Graph for business rules and lineage dependencies.
Pre-Execution Reasoning:Granite 4.2 leverages its reasoning budget to trace the SPO graph (Table_A$\$xrightarrow{\text{contains}}SSN$\$xrightarrow{\text{governedBy}}Policy_102).It verifies that its proposed code or SQL transformations won't break upstream dependencies or violate policies.
Execution & Audit Trail:Granite 4.2 executes the transformation.ArcXA commits the outcome as a new, immutable SPO triple (e.g., [Transformation_99] ---> [validatedBy] ---> [Granite_Agent_4.2]) for instant compliance auditability.
Key Enterprise Benefits
Zero-Hallucination Schema Mapping:Instead of guessing SQL transformations, Granite 4.2 is bound by the deterministic rules of ArcXA’s SPO graph.
Pre-Execution Validation:Catch semantic errors (like unit mismatches or unmasked PII) before pipelines run, preventing costly post-load reconciliations.
30-Second Audits:Compliance teams can trace every AI decision back through explicit SPO lineage nodes to explain why a transformation occurred.
Equitus and its ArcXA platform function as a Semantic Control Plane (SCP), leveraging an ISV relationship with IBM (specifically centered on IBM Power10 hardware and Knowledge Graph Neural Networks / KGNN architectures) to re-engineer cross-system migrations.
By embedding a Triple Store model (Subject – Predicate – Object), ArcXA elevates data migrations out of rigid ETL scripts and into a semantically-governed metadata overlay.
Key Architectural Pillars
1. Hardware & Runtime Alignment (IBM Power Systems)
On-Premise Inferences:ArcXA and Equitus KGNN are optimized for IBM Power10 hardware, exploiting its Matrix Math Accelerator (MMA) engines.This allows localized graph calculations, vector embedding matching, and semantic reasoning directly on enterprise data cores (z/OS mainframes or Power Systems) without sending data to public clouds.
High-Throughput Local Graph Sharding:Utilizing native arcxa-shard RDF/SPARQL runtimes, ArcXA scales triple store lookups across distributed memory spaces, enabling real-time validation during massive legacy-to-cloud transfers.
2. The Semantic Control Plane (SCP)
Traditional migration tools move rows from Source Table A to Target Table B using static schema mappings. As an SCP, ArcXA sits above existing ETL pipelines:
Decoupled Execution:ETL handles heavy lifting/data transport, while ArcXA governs intent, context, and schema lineage.
Policy-Driven Validation:Ensures cross-system consistency by executing constraints against the active ontology, blocking invalid transformations before target persistence occurs.
3. Enhancing Migrations via Triple Stores (S – P – O)
Instead of flattening complex relationships into relational tables, data entities and mappings are stored as knowledge graph triples:
{Subject (Source Entity)}--->{Predicate (Semantic Relationship)}} {Object (Target / Standard Ontology)}
Contextual Mapping: A legacy IBM mainframe field CUST_LST_NM is mapped via triples:
(S) [db2:CUST_LST_NM] -> (P) [owl:sameAs] -> (O) [core:CustomerLastName]
Lossless Schema Evolution:When moving from a mainframe COBOL copybook/DB2 schema to a modern cloud database, field definitions, dependencies, and business meanings are preserved regardless of structural differences.
How Equitus ArcXA Leverages this Architecture for Cross-System Migrations👍
PowerGraph Proposes - Equitus ARCXA 's integrating triple store architecture with IBM Power10/Power11 SQL on z/OS , Db2 for z/OS , and SAP HANA establishes a zero-ETL, semantic data layer for CCAR (Comprehensive Capital Analysis and Review) oversight.
ARCXA uses an RDF (Resource Description Framework) triple store data plane ( arcxa-shard) to normalize legacy banking tables without physically moving or altering the underlying databases.
Dynamic Ontology Mapping: Translates native schema names across DB2 and SAP HANA into a single standardized CCAR ontology (eg, mapping CUST_RISK_RATand HANA_CREDIT_SCOREinto ccar:CreditRiskScore).
Cryptographic Lineage Chains: ARCXA captures transformations at the rule and value level.Every calculation used in stress-testing carries a tamper-evident audit trail back to its source record—addressing strict federal examination requirements.
Pre-Execution Anomaly Detection: Validates schema changes and flags missing fields (eg, unassigned collateral types) before data reaches regulatory risk models.
2. IBM Power10/Power11, z/OS, and Db2: Core Data Engine
Equitus Arcxa is based in KGNN, which runs natively on IBM Power Mainframes running z/OS and Db2 store the bulk of commercial and consumer loan portfolios.
In-Database SQL Federations: IBM Power10/11 processors handle federated SQL queries natively across Db2 for z/OS and external systems, letting ARCXA query core banking tables in situ using virtualization.
Matrix Math Accelerator (MMA): Power10/11 hardware features built-in MMA accelerators.When ARCXA runs SPARQL or SQL queries to build graph models for loss projections, MMA accelerates dense matrix calculations directly on the mainframe without needing external GPU clusters.
Mainframe Reliability: Ensures transactional integrity and zero downtime for continuous loan exposure reporting.
3. SAP HANA: High-Speed In-Memory Analytics
SAP HANA operates as the high-speed engine for real-time financial tracking and sub-ledger accounting.
In-Memory Graph Engine: HANA's native Graph Engine works with ARCXA's RDF model to evaluate complex borrower networks, guaranteeing hierarchies, and collateral relationships at scale.
Real-Time Stress Testing: As macroeconomic shocks (eg, unemployment rates, commercial real estate declines) are applied, HANA calculates loss provisions across sub-ledgers instantly.
ARCXA - Comprehensive Capital Analysis and Review (CCAR)
"CCAR submissions are auditable only when you can trace every loan → every capital charge → every regulatory line item. Today that's manual and error-prone. ArcXA's semantic control plane (SCP) on IBM Power 10/11 makes that lineage automatic. You don't need to migrate to the cloud. Your existing Power infrastructure becomes audit-ready, and your stress-test reruns go from hours to minutes."
Acting as an intelligence connection layer, adds a mapping intelligence and data lineage layer that sits on top of legacy core banking infrastructure.
Arcxa enhances today's CCAR Problem - manual, risky CCAR workflows:
Sample queries -
Compliance analyst queries DB2: "Pull all commercial real estate loans originating Q1-Q4"
Data lands in Excel. Counterparty mappings checked by hand. Market data merged manually.
Stress-test model runs (Python, SAS, or proprietary code). Capital charges calculated.
Regulatory submission: "Why did Loan ABC get 8.5% capital charge vs. 7.2%?" → Audit trail is weak.
Fed audits filing. "Walk us through the logic." → 3 weeks of manual reconciliation.

ArcXA Solution: Migration Readiness Assessment
CCAR requires banks to stress-test credit risk, demonstrate clear regulatory capital adequacy, and maintaintamper-evident data lineage for federal auditors.
Arcxa tames the CCAR Multi-System Problem
Today's setup:
z/OS DB2 (mainframe) → Core loan origination, counterparties, master data
IBM Power 10/11 DB2 → Risk ratings, collateral valuations, exposure calculations, stress-test parameters
SAP HANA → Market feeds, regulatory consolidation, financials, CCAR reporting layer
The pain:
Loan data lives in z/OS. Risk data in Power. Market/reporting in HANA.
CCAR requires a single loan object with all data linked: origination + risk + market + regulatory mapping.
Manual reconciliation across systems = weeks of rework before Fed submission.
"Why did we bucket Loan_ABC differently this quarter?" → Requires tracing across three database schemas.
Stress-test reruns mean touching all three systems, waiting for ETL sync cycles.

PowerGraph Proposes: Ai BANKING COMPLIANCE CCAR SYSTEMS;
Equitus ARCXA alongside KGNN (Knowledge Graph Neural Networks) on IBM Power10/Power11 (running z/OS or Linux with MMA matrix acceleration) creates a high-performance stack for accelerating CCAR (Comprehensive Capital Analysis and Review) compliance and loan portfolio oversight.
ARCXA serves as the mapping intelligence and data lineage layer sitting on top of legacy core banking infrastructure.
Unified Loan Schema Mapping:ARCXA normalizes disparate loan data (e.g., commercial real estate, syndicated loans, retail mortgages) across multiple core systems into a single standardized CCAR ontology without requiring full ETL redesign.
Tamper-Evident Audit Chains: Federal regulators require end-to-end data provenance for stress-test models. ARCXA generates a cryptographic audit chain at the rule and value level, verifying exactly how loan numbers were calculated and transformed.
Zero-Trust Anomaly Detection:ARCXA flags null values, missing collateral disclosures, or schema anomalies before loan data reaches regulatory stress-testing pipelines.
2. Triple Store & KGNN: Deep Graph Risk Modeling
Rather than storing loan data in isolated tabular databases, a RDF Triple Store (Subject-Predicate-Object) structures credit exposure into a Knowledge Graph.
Contextual Entity Linking:Connects borrowers, guarantors, ultimate beneficial owners (UBOs), collateral assets, and macroeconomic risk factors in a single interconnected graph.
Graph Neural Network (KGNN) Reasoning:KGNNs run machine learning over the RDF graph to uncover complex, hidden risk patterns—such as contagion risk, concentration risk across interconnected subsidiaries, or hidden collateral re-hypothecation.
Stress-Testing Simulation: During CCAR scenario runs (e.g., severe recession or interest rate spikes), KGNN propagates financial shock through graph edges to predict non-performing loan (NPL) default cascades.
3. IBM Power10/Power11 z/OS & MMA Hardware Engine
Equitus Arcxa runs on IBM’s enterprise ecosystem delivers the extreme compute and sub-second transaction throughput required for massive loan portfolios.
MMA (Matrix Math Accelerator): IBM Power10 and Power11 processors feature built-in hardware acceleration specifically designed for dense matrix operations. This allows the graph neural network (KGNN) inference and deep-learning stress models to execute inline directly where the core banking data lives—eliminating slow network egress to external GPU clusters.
Co-location on z/OS / IBM Power: Mainframe core banking environments host the live loan books. Executing ARCXA and KGNN within the same hardware boundary dramatically speeds up raw data ingestion and RDF triple creation for CCAR reporting cycles.
Hardware-Level Encryption & Security: Supports the high confidentiality requirements for sensitive institutional borrower profiles and financial statements.
End-to-End CCAR Workflow Integration
Summary of Key Benefits
Hours instead of weeks:Reduces CCAR aggregation and stress-test data assembly cycles significantly.
Defensible compliance:Regulators can trace every metric back to its origin field with cryptographic proof via ARCXA.
Systemic risk visibility:KGNN spots hidden leverage and concentration risk that traditional relational databases miss.
In-situ execution:IBM Power MMA hardware handles deep learning calculations locally on mainframe-grade systems without moving sensitive bank data.
