The definitive technical foundation of Sifta. Engineered for bank-grade isolation, high-currency throughput, and total autonomous security.
Core Infrastructure
Built on Hono (Node.js) and TypeScript — strict data typing, high stability, and resilience to errors. Powered by Better-SQLite3 in Write-Ahead Logging (WAL) mode for instant reads and writes with no latency.

Multi-Tenant Isolation
Designed strictly around a Shared-Application, Isolated-Data pattern. Every enterprise (Tenant) operates within physically and logically segregated data domains and directory structures.
Multi-layered Identity and Access Management (IAM). All sensitive keys and KSeF tokens are encrypted at rest using AES-256-CBC, with PBKDF2 (SHA-512) for password hashing.

DLP & Anomaly Guard
Integrated Data Loss Prevention engine scans all OCR extractions and text for leaked cloud secrets (AWS, Google) or financial data (BIP39 Seed Phrases, Cards) before they touch the database.
A continuous data pipeline that transforms raw uploads into corporate knowledge. Includes a unique 'Knowledge Purgatory' staging phase before AI semantic synthesis and tokenization.

Real-Time WebSocket Protocol
A bidirectional streaming layer built on WebSockets (Node-WS) — real-time streaming of AI responses and instant alerts across the organization.

Definitive Access Model (RBAC)
Sifta operates on a strict three-tier hierarchy: Employee, Manager, and Administrator. Data visibility is enforced mathematically at the database layer. Managers can generate performance summaries exclusively for their direct reports, while AI Agents respect the caller's execution policy boundaries.
