01d. Technical Rollout Roadmap
This implementation roadmap sequences prioritized user stories into SAFe Program Increments (PIs), ensuring Must-Have compliance and detection capabilities deliver early risk mitigation value. The strategy addresses core anomaly detection first to solve for high false-positive rates before scaling into agentic triage and autonomous resolutions.
This sequencing de-risks delivery by prioritizing compliance-driven Must-Have stories in Phase 1, aligning with fintech regulatory pressures. Under SAFe, each PI includes enabler spikes (e.g., zero-trust policy implementation) to ensure architectural integrity during ART (Agile Release Train) synchronization.
02. Multi-Agent Design: The Autonomous Compliance Swarm
FinRisk Sentinel moves beyond traditional monolithic AI to a Hierarchical Orchestration Pattern. By utilizing a central "Supervisor" to delegate specialized tasks to a "Swarm" of domain-expert agents, we ensure that each agent operates with a minimal context window, thereby reducing hallucinations and maximizing investigative precision in safety-critical banking environments.
1. The Swarm Architecture: Role-Based Specialization
| Agent Persona | Cognitive Engine | Tooling / GCP Integration | Governance Guardrail |
|---|---|---|---|
| The Triage Supervisor | Gemini 1.5 Pro | Vertex AI Orchestration, Pub/Sub Triggers | Zero-Draft Policy: Cannot finalize reports; only routes and delegates. |
| The Anomaly Detective | BigQuery ML (XGBoost) | BQML Anomaly Detection, Cloud Dataflow | Precision Threshold: Must provide a confidence score > 0.7 to trigger swarm. |
| The Entity Investigator | Gemini 1.5 Flash | Vertex AI Search, GCP Spanner (Graph) | PII Masking: Mandatory call to DLP API before processing. |
| The Compliance Auditor | Gemma 2 (Fine-tuned) | Policy-as-Code (YAML), Secret Manager | Adversarial Check: Must find at least one "Critical Weakness." |
2. Agentic Design Patterns & Technical Moats
Collaborative Reasoning
Uses Dynamic Task Delegation. Detective alerts trigger "Sub-Crew" deep-dives via Vertex AI Extensions to external AML watchlists.
The HITL Guardrail
Self-Correction Loop where agents review narratives against Policy-as-Code. Scores < 85% trigger Case Brief generation for humans.
Deterministic Backbone
