+# 🏢 Enterprise Tooling & Governance Engine
+
+> Architectural specification and system design for the SCIBASE Enterprise Administration, Analytics, and Institutional Compliance Suite.
+
+---
+
+## 1. Overview & Objectives
+
+The Enterprise Tooling layer transforms SCIBASE into mission-critical infrastructure for universities, research institutes, and enterprise R&D divisions. It equips institutional administrators, department heads, and compliance officers with:
+- **Centralized Administrative Dashboards:** Real-time visibility across research labs, compute quotas, and asset registries.
+- **Role-Based Governance (RBAC) & Single Sign-On (SSO):** SAML 2.0 / OIDC integrations with institutional identity providers (Okta, Azure AD, Shibboleth).
+- **Audit Logs & Export Pipelines:** Tamper-evident, compliance-ready event logs (SOC2, HIPAA, GDPR).
+- **Automated Research IP & License Enforcement:** Policy engines ensuring proper dual-licensing, embargoes, and export compliance.
+
+---
+
+## 2. Institutional Architecture
+
+```mermaid
+graph TD
+    A[Institutional Admin / SSO] --> B[Enterprise Gateway]
+    B --> C[Admin Dashboard Service]
+    B --> D[Compliance & Audit Engine]
+    B --> E[Resource Quota & Billing Hub]
+
+    C --> F[(Organization Data Lake)]
+    D --> G[(Immutable Audit Ledger)]
+    E --> H[Slurm / Kubernetes Compute Nodes]
+```
+
+---
+
+## 3. Core Capabilities & Specifications
+
+### A. Admin Dashboard & Contributor Analytics
+- **Project Telemetry:** Real-time metrics on public/private repositories, active datasets, and model checkpoints.
+- **Activity Heatmaps:** Cross-departmental collaboration graphs and researcher output velocity.
+- **Compute & Storage Utilization:** Track GPU hours, cloud storage tiers (S3/GCS/Glacier), and egress quotas by department.
+
+### B. SSO, SCIM & Identity Provisioning
+- **Protocols Supported:** SAML 2.0, OpenID Connect (OIDC), OAuth2.
+- **SCIM 2.0 Automated User Provisioning:** Automatically syncs lab members, roles, and project permissions directly from university Active Directory.
+- **Multi-Tenant Hierarchy:** Organization → Department → Lab → Research Project.
+
+### C. Security, Compliance & Audit Logging
+- **Event Capture:** All sensitive actions (data access, IP downloads, role modifications, API key issuance) are recorded with cryptographically signed timestamps.
+- **Export Formats:** Automated streaming to SIEM pipelines (Splunk, Datadog, AWS CloudWatch) in CEF/JSON format.
+
+---
+
+## 4. API Endpoints Reference
+
+| Method | Endpoint | Description | Auth Scope |
+| :--- | :--- | :--- | :--- |
+| `GET` | `/api/v1/enterprise/overview` | Aggregated institutional stats & active compute | `admin:read` |
+| `GET` | `/api/v1/enterprise/audit-logs` | Filterable, paginated compliance event stream | `audit:read` |
+| `POST` | `/api/v1/enterprise/sso/config` | Update SAML/OIDC metadata & certificate bundles | `admin:write` |
+| `GET` | `/api/v1/enterprise/quotas` | Departmental storage & GPU quota usage breakdown | `admin:read` |
+| `POST` | `/api/v1/enterprise/export-report` | Generate SOC2/audit PDF & CSV compliance bundles | `admin:write` |
+
+---
+
+## 5. Security & Verification Checklist
+- [x] SAML 2.0 assertions verified with SHA-256 signatures.
+- [x] SCIM 2.0 token authentication with strict rate limits.
+- [x] Audit logs stored in append-only immutable storage.
