# FOSO IURIS

> FOSO IURIS is a sovereign on-premise legal AI appliance engineered for tier-1 law firms, arbitration panels, notaries, and M&A due diligence teams. It executes neural models 100% locally on dedicated sovereign hardware with kernel-level socket isolation (strictly loopback 127.0.0.1 and ::1), generating an immutable SHA-256 chained cryptographic audit trail for every processed folio.

The system is built around Spanish and European procedural law (LEC, LOPJ, LexNET, and the EU AI Act). It assists qualified legal practitioners without replacing judicial discretion or providing independent legal advice. Regulatory citations (Art. 542.3 LOPJ, Art. 199 Código Penal, Art. 28 GDPR) describe deliberate engineering architecture, eliminating third-party cloud data transmission, telemetry, and foreign subpoena vulnerability (e.g., US CLOUD Act).

## Critical Technical Facts
- **Air-Gap Network Isolation**: Enforced at operating-system kernel socket level. Any attempt to route TCP/UDP packets outside loopback (`127.0.0.1` or `::1`) is immediately dropped and logged.
- **Hardware Enclave**: Dedicated sovereign architectures featuring high-bandwidth Unified Memory Architecture (UMA / VRAM):
  - *Enterprise Sovereign Enclave*: 128 GB Unified Memory / VRAM, up to 800 GB/s bandwidth (large multi-partner litigation & virtual data room M&A).
  - *Compact Sovereign Enclave*: 64 GB Unified Memory / VRAM, high-speed neural pipeline (compact notarial & boutique litigation practice).
- **Evidentiary Chain of Custody**: Cryptographic Merkle-chained SHA-256 hashes generated for every document ingested, OCR-extracted, and queried, conforming to Arts. 299 and 326 of the Spanish Civil Procedure Act (LEC).
- **Local Ingestion & OCR**: Local neural OCR accelerated directly via dedicated on-chip tensor engines; scanned PDFs and court briefs never transit through third-party optical servers.
- **Procedural Engine Suite**:
  1. *Cronómetro Forense*: Automated procedural timeline extracting dates, notifications, and hearings from multi-thousand-page case records.
  2. *Detector Forense de Contradicciones*: Folio-by-folio semantic contradiction detector across witness depositions, expert reports, and written briefs.
  3. *Simulador de Contraparte Adversarial*: Adversarial argument rehearsal predicting opposing counsel's dilatory pleas and preliminary objections (Art. 416 LEC).
  4. *Calculadora Procesal de Plazos y Preclusión*: Strict computation of judicial deadlines under the Spanish LEC and LexNET, automatically excluding non-working days (August judicial recess under Art. 130.2 LEC, weekends, official national/regional court holidays) with the 15:00 h grace period (Art. 135.5 LEC).
- **Physical Security**: Hardware XTS-AES-256 storage encryption tied to a dedicated HSM cryptoprocessor, tamper-evident physical chassis seals, and disabled wireless/Bluetooth kernel modules.

## Legal Homologation & Regulatory Posture
- **Attorney-Client Privilege (Secreto Profesional)**: Designed to satisfy the absolute duty of confidentiality under Art. 542.3 of Spain's Organic Law of the Judiciary (LOPJ) and avoid felony disclosure of secrets under Art. 199 of the Spanish Criminal Code (Código Penal).
- **EU AI Act Alignment**: High-Risk legal AI classification compliance (human-in-the-loop oversight, zero biometric categorization, zero emotional analysis, local deterministic audit logging).
- **GDPR / RGPD**: Absolute data sovereignty. Because no personal data is transferred to external servers, no international data transfer agreements (SCCs) or multi-tenant sub-processor risks (Art. 28 GDPR) are triggered.
- **US CLOUD Act Immunity**: Hardware and data reside exclusively within the firm's physical jurisdiction, legally immune from foreign extra-territorial subpoenas.
