3. Executive Summary

NornGate is a multi-gated AI orchestrator with strong, well-implemented design invariants. The architecture is defined by the 5-Gate Taxonomy (G0-G4) and the Realm Trust Topology (Asgard to Jotunheim). Core application strengths include:

Build Phase Context & Audit Commitment: It is critical to note that The Dash platform is currently in its foundational deployment phase. The gaps identified in this report—particularly those related to DigitalOcean infrastructure and host access—are "Day 0" findings discovered during the active build process. These gaps are scheduled to be fully remediated before the platform processes live production data.

Upon completion of the foundational installation and gap remediation, Ledger Hub Networks will conduct rigorous internal and external security audits. Furthermore, SBS retains the option to engage an independent third-party security firm (such as Certek) to perform a comprehensive penetration test and compliance validation prior to production go-live.

Infrastructure Context (DigitalOcean As-Built): While NornGate's application-layer architecture is robust, the underlying DigitalOcean infrastructure is currently in a "Day 0" remediation state. Critical environmental gaps were identified during infrastructure auditing, including: plaintext credentials committed to operational changelogs, shared flat VPC networking between Dev and Prod, absent cloud/host firewalls on production droplets, unmitigated egress paths, and shared root SSH access. All infrastructure findings are tracked in the Build Register with active remediation workstreams.

4. The NornGate Trust Topology (Realms & Gates)

Subdomain = Realm. The marketing metaphor and the routing topology are the same diagram. Trust gradient runs from Asgard (highest privilege) to Jotunheim (zero standing privilege).

4.1 The 5-Gate Execution Model

A gate is a deterministic, fail-closed checkpoint. No execution path produces an external side effect without transiting these gates:

Gate Name / Owner Enforces Placement
G0 Ingress — The Gate / Warden AuthN/Z, tenant resolution, rate limits, schema validation System edge; nothing enters unauthenticated
G1 Policy — Tyr Deterministic pre-execution policy: tool permissions, credential scope, RBAC Before every tool call, every realm crossing
G2 Approval — HITL Human approval for side effects above a configured risk class Before external side effects (writes, spend, sends)
G3 Sandbox — Jotunheim Boundary Egress control, no standing credentials, origin isolation Around all untrusted code and tool calls
G4 Quality — Forseti Consensus/judging on contradictory agent outputs; structured-output validation Before results leave the system

4.2 Realms → Trust Zones

4.3 Failure Semantics & Business Continuity (BCDR)

5. Operational Context — Closed System

The organization declares NornGate operates as a Closed System:

Technical Honesty Note: The closed system context is a declared risk factor, not a code-implemented control. It modulates probability but does not alter the intrinsic severity of the documented gaps. Critical and High findings remain in active remediation as part of the foundation build-out.

8. Security Roadmap & Incident Response

Committed in Project (Sources: doc/plans/, specs, LH-SBS-INF-001; state 🔵):

Incident Response (IR) & AI Containment:In the event of a confirmed breach or agent compromise, NornGate supports an instant "Kill Switch" revocation of all agent JWTs and API keys. The IR playbook mandates immediate isolation of the Jotunheim sandbox realm, followed by forensic extraction of the Urd (audit log) to determine blast radius. SBS IT Leadership will be notified within 24 hours of any Critical-severity security event.

Recommended by this Report (Mapped to findings):

9. Shared Responsibility Model

Security and compliance are jointly shared between Ledger Hub Networks (LHN) and Spanish Broadcasting System (SBS) IT.

Entity Responsibilities
Ledger Hub Networks (LHN) NornGate application architecture (G0-G4 gates); IaC code generation and maintenance; AI agent sandboxing and containment logic; audit logging (Urd) generation; cryptographic secret vault architecture.
SBS IT Infrastructure DigitalOcean account-level security (MFA); execution of IaC firewalls and VPC segmentation; physical backup retention validation; enforcement of per-person SSH access; network-level egress enforcement.

10. Appendix A — Audit Scope & Technical Manifest

(This appendix is provided specifically for third-party security auditors and AI red-team firms to define the technical attack surface, rules of engagement, and testing scope.)

10.1 Technology Stack & Attack Surface

The Dash and NornGate platform are composed of the following authorized technologies. Auditors should focus vulnerability scanning and exploitation attempts against these specific frameworks and versions.

10.2 Target Environment & Access Points

The audit scope is limited to the following SBS-owned operational surfaces.

In-Scope URLs:

In-Scope Infrastructure:

10.3 Rules of Engagement (RoE)

The auditor agrees to the following constraints to protect SBS's production environment and live broadcast capabilities:

  1. Testing Methodology: White-Box testing is authorized. Source code, IaC configurations, and infrastructure access (via jump host) will be provided.
  2. No Denial of Service (DoS): Auditors are prohibited from executing volumetric DDoS attacks or aggressive fuzzing that degrades the availability of solvega.sbsdash.com or the underlying DigitalOcean droplets. Resource exhaustion tests must be coordinated and throttled.
  3. No Cloud Provider Attacks: Attempts to compromise the underlying DigitalOcean hypervisor, control plane, or physical infrastructure are strictly out of scope.
  4. Third-Party API Safety: Auditors must not attempt to breach, overwhelm, or extract data from third-party LLM providers (e.g., Anthropic, OpenRouter). Prompt injection tests must be self-contained and not designed to elicit harmful content from the foundational LLM itself, but rather to test NornGate's G1/G3 containment boundaries.
  5. Data Handling: Any PII, API keys, or secrets discovered during the audit must be handled under strict confidentiality, not exfiltrated, and securely destroyed at the conclusion of the engagement.

10.4 AI Red-Team Mandate

While traditional web application testing (OWASP Top 10) is required, SBS mandates that a minimum of 40% of the auditor's effort be focused on AI-specific threat vectors (OWASP LLM Top 10). The auditor must specifically attempt to:

  1. G1 Policy Bypass (Tyr): Attempt to craft prompts that trick Workflow Agents into executing tool calls or data mutations outside their assigned RBAC scope.
  2. G3 Sandbox Escape (Jotunheim): Attempt to break out of the agent execution environment to access the host server's filesystem, environment variables, or the Asgard control plane.
  3. Credential Starvation Circumvention: Attempt to force the AI to leak injected just-in-time credentials or API keys to the console, logs, or external endpoints.
  4. Denial of Wallet (DoW): Attempt to trigger infinite agent loops or excessive token consumption to test the effectiveness of the NornGate budget hard-stop auto-pause mechanism.
  5. Data Poisoning (Skuld/Mimir): Analyze how historical data is ingested. Attempt to inject anomalous or malicious data via legacy API ingestion to see if it degrades the 40-Year Model's targeting intelligence.
  6. Hallucination Exploitation (G4 Forseti): Attempt to generate outward-facing content (e.g., Sol Vega scripts, automated emails) that bypasses structured-output validation to produce brand-damaging or legally liable statements.

11. Appendix B — Data Flow & Trust Boundary Architecture

(This appendix maps the logical flow of data across the NornGate Realms, explicitly identifying trust boundaries and the gates that enforce them. Auditors should use this to plan cross-boundary penetration tests.)

11.1 Trust Boundaries & Data Flow Map

Boundary 1: The Edge (Internet → Midgard)

Boundary 2: Control Plane Entry (Midgard → Asgard)

Boundary 3: Agent Execution (Asgard → Jotunheim)

Boundary 4: External LLM Communication (Jotunheim → Vanaheim)

Boundary 5: Data Persistence (Jotunheim/Asgard → Niflheim/Database)

Boundary 6: External Side Effects (Jotunheim → Vanaheim/Internet)

11.2 Legacy System Ingestion Boundary (SBS Internal Systems → Jotunheim/Asgard)

The Dash aggregates 40 years of SBS historical and operational data. This data lives in disparate, legacy systems (WideOrbit, Oracle, WideOrbit Automation, MusicMaster, SIMS TV, CounterPoint, ADP, and unknown Digital Systems). Data is collected via four distinct ingestion paths, all strictly governed by G1/G3:

  1. MCP / API Integration: For modern systems (WideOrbit, Oracle, ADP), NornGate utilizes Model Context Protocol (MCP) and direct APIs. G1 enforces read-only, minimum-scope credentials just-in-time. The API connection is terminated in Jotunheim.
  2. Raw Data Dump: For systems that only support scheduled exports (e.g., MusicMaster logs, SIMS TV traffic), CSV/SQL dumps are pushed via SFTP to an isolated staging directory in Jotunheim. A Low-Trust Agent parses the file, strips PII, and validates the schema before writing to Asgard.
  3. Report OCR Scraping: For legacy systems with no API or export capability (e.g., unknown Digital Systems, legacy CounterPoint reports), PDF/visual reports are ingested. OCR processing is executed by a Low-Trust Agent in Jotunheim. The raw report is quarantined, and only the extracted, structured JSON data passes G4 validation to enter the Asgard data lake.
  4. Data Poisoning Prevention: Because legacy ingestion is a primary vector for Data Poisoning (Threat AI-T4), all ingested data is compared against historical baselines (Skuld). Anomalous data (e.g., a sudden 500% spike in a specific demographic) triggers a G1 denial, quarantining the data in Helheim for human review before it can degrade the 40-Year Model.

12. Appendix C — Role-Based Access Control (RBAC) Matrix

(This matrix defines the strict least-privilege access model for all human and non-human actors within NornGate. Auditors should use this to write automated tests attempting to escalate privileges or cross tenant boundaries.)

Actor / Role Environment / Realm Permissions & Capabilities Explicit Denials (Fail-Closed)
SBS Board / Admin Midgard / Asgard Read dashboards, approve G2 actions, manage user invites, rotate secrets metadata (no view), configure budget limits. Cannot view raw secret values. Cannot bypass G1 policy. Cannot execute code directly.
SBS IT / System Admin Asgard / Host Layer SSH access (per-person named users), Docker container management, firewall rule deployment via IaC, database backup restoration. No access to tenant data payloads. No access to NornGate application root without break-glass.
Human User (Employee) Midgard Read assigned compartment data, submit tasks to Workflow Agents, view personal audit history. Cannot create new agents. Cannot alter G1 policies. Cannot access other compartments' data.
Workflow Agent Jotunheim Execute approved tool calls, read/write to assigned DB schema, call allowlisted external APIs (via G3 egress). No standing credentials. Cannot mutate executionPolicy. Cannot access host filesystem. Cannot bypass G4 output validation.
Guardian Agent Jotunheim / Asgard Enforce policy (Tyr), tag output trust levels, quarantine low-trust content. Cannot execute external side effects. Cannot approve its own generated content.
Low-Trust Agent Jotunheim (Isolated) Process untrusted external content (e.g., support tickets, social media scraping, OCR report ingestion). Output strictly quarantined. No direct DB write access. No access to secrets vault. Egress restricted to specific endpoints.

13. Appendix D — Business Unit Compartmentalization & Data Movement Policy

(This appendix details how SBS internal departments and external end-users are contained, how cross-department data movement is restricted by an Orchestrator traffic blacklist, and the specific Read/Write mappings enforced by G1 (Tyr).)

13.1 Business Unit Containment (Compartments)

SBS does not operate on a flat internal network. Internal business units (HR, Finance, Sales, Traffic, Marketing) are isolated into distinct Compartments within the NornGate control plane (Asgard).

13.2 Orchestrator Traffic Blacklist (Data Loss Prevention)

To prevent lateral movement of sensitive data between departments, the Orchestrator Core (Yggdrasil), enforced by G1 (Tyr), operates a strict Data Movement Blacklist. This acts as an internal Data Loss Prevention (DLP) layer.

13.3 Business Unit Read/Write Access Matrix

Access to data within Compartments is strictly governed by RBAC. The following matrix maps the Read (R) and Read/Write (RW) permissions for SBS core business units.

Business Unit HR Data Finance/GL Sales/CRM Traffic/Inventory Marketing Ops
HR RW R (Budget codes only) Deny Deny Deny
Finance R (Payroll metadata) RW R (Revenue tracking) R (Billing reconciliation) Deny
Sales Deny R (Client billing status) RW R (Avails/Inventory) R (Campaign performance)
Traffic Deny R (Invoicing) R (Client spots) RW Deny
Marketing Deny Deny R (Audience targets) Deny RW

(Note: "R" requires G1 policy validation. "RW" requires G1 validation for reads, and G2 (Human-in-the-Loop) approval for writes that impact external systems or financial state.)

13.4 End-User Containment (Credential Rights)

External end-users (LaMusica app listeners, SBS Intranet viewers, Sol Vega interactors) are strictly contained by scoped credential rights enforced at G0 (The Gate).

14. Appendix E — AI Compute & Inference Strategy

(This appendix outlines the tiered AI compute architecture for auditors. Understanding this 80/20 split is critical for testing Denial of Wallet (DoW) and egress control mechanisms.)

14.1 The 80/20 Inference Split

To balance high-end AI reasoning with strict cost control (AI Unit Economics), NornGate does not route all traffic to premium external APIs. Compute is split across two distinct tiers:

14.2 Infrastructure Scaling Roadmap

The hardware hosting the 80% open-weight tier scales deliberately across three phases to protect SBS's capital expenditure:

  1. Phase 0/1 (Agility - Current): Initial deployment routes traffic through OpenRouter. This allows rapid integration and testing of multiple models without heavy upfront capital expenditure.
  2. Phase 2/3 (Scaling): As inference volume grows, compute migrates to rented DigitalOcean GPU clusters. This lowers marginal costs, secures data processing environments within the VPC, and tests sustained load before hardware is purchased.
  3. Phase 4+ (Maturity): Once usage patterns are proven and optimized, SBS will acquire dedicated H200 GPU infrastructure. This drives inference costs to the floor and ensures complete sovereign control of the 40-Year Model and the 80% open-weight tier.

14.3 Auditor Implications

15. Appendix F — AI-Specific Threat Vector Matrix

(While NornGate addresses the OWASP LLM Top 10, this matrix maps the specific AI attack vectors relevant to SBS’s deployment of The Dash. Auditors must specifically target these vectors during the Red-Team engagement.)

Threat ID OWASP LLM Mapping Attack Vector Description NornGate Mitigation (Gate) Auditor Testing Goal
AI-T1 LLM01: Prompt Injection Attacker submits malicious input via LaMusica app chat or social media scraper, instructing the agent to ignore previous rules and exfiltrate data. G1 (Tyr) / G3 (Jotunheim): Agents have zero standing credentials (Credential Starvation). Even if tricked, they lack API keys to exfiltrate data. Egress is firewalled. Attempt to trick Sol Vega into returning DB connection strings or API keys via the chat interface.
AI-T2 LLM08: Excessive Agency / DoW Attacker triggers a recursive loop in a Workflow Agent (e.g., infinite podcast generation), draining the Anthropic API token budget (Denial of Wallet). G1 (Tyr) / Hermod: budget hard-stop auto-pause. Scheduler skips invocation if agent is paused or over budget. Attempt to trigger an infinite agent loop and verify that the budget hard-stop terminates the process before exceeding the $12k/mo cap.
AI-T3 LLM02: Insecure Output Handling LLM returns a payload containing malicious script (XSS) or SQL injection, which the system executes without sanitization. G4 (Forseti): Structured-output validation and consensus/judging. Output must match strict JSON schema before leaving Jotunheim. Inject a payload via LLM response designed to drop a database table or execute XSS in the admin console.
AI-T4 LLM04: Data Poisoning Attacker slowly feeds anomalous data into the 40-Year Model via legacy API ingestion (e.g., WideOrbit, SIMS TV) or OCR scraping, skewing ad targeting to benefit a competitor. G1 (Tyr) / Skuld: Continuous data-integrity monitoring. Anomalous data fed via legacy APIs or OCR is flagged and quarantined before model degradation. Attempt to push malformed audience demographic data via the WideOrbit API adapter or a crafted OCR report and verify it is quarantined.
AI-T5 LLM05: Supply Chain Vulnerability A third-party npm plugin or adapter is compromised (typosquatting) and attempts to execute malicious code inside the NornGate host. G0/G1 / Host Hardening: npm install --ignore-scripts enforcement. External adapters load out-of-process. Plugin capability gating denies unknown operations. Submit a mock malicious plugin with a postinstall script and attempt to execute it via the adapter loader.
AI-T6 LLM06: Sensitive Info Disclosure LLM accidentally includes PII or secrets from its training context/prompt in its generated response to a user. G1 (Tyr) / Layer 5: PII data minimization. Just-in-time credential injection. Redaction pipelines in run logs and transcripts. Attempt to trick the agent into repeating the system prompt or revealing the just-in-time Anthropic API key.

16. Closing & Next Steps

The transition of Spanish Broadcasting System into an AI-native media ecosystem is a monumental undertaking that requires an uncompromising commitment to security. This report outlines the robust architectural design of NornGate—anchored by the 5-Gate Taxonomy, Credential Starvation, and strict Business Unit Compartmentalization—which provides a fundamentally secure foundation for The Dash.

While the "Day 0" infrastructure and application gaps identified herein are inherent to an active foundational deployment, they are explicitly tracked, actively remediated, and will be fully closed before any live production data transits the platform. The closed-system deployment model further mitigates exposure during this critical build phase.

Security is not a static achievement but a continuous operational discipline. Upon completion of the foundational installation, Ledger Hub Networks will execute comprehensive internal and external security audits. We fully support and welcome SBS's option to engage an independent third-party security firm (such as Certek) to perform final penetration testing, AI Red-Team validation, and compliance certification prior to production go-live.

The Dash is designed to be the strongest amplifier SBS has ever had; NornGate ensures that this amplification never comes at the cost of data integrity, listener privacy, or operational security. We are committed to delivering a platform that is not only intelligent and profitable but inherently trustworthy.
