1. Overview

Synthium DataHub is Caseway’s enterprise intelligence layer for organizations that need governable, explainable automation over documents, structured records, and multi-source operational data. It is designed for environments where wrong answers create compliance, safety, or mission risk — not consumer chat demos.

The platform ingests heterogeneous sources, structures and validates them against policy, and exposes trusted outputs through APIs, embeddings, and operator-facing decision workflows. Human approval gates remain first-class controls.

2. Reference architecture

Synthium is organized as a governed pipeline rather than a single model call. Each stage produces durable artifacts that can be inspected, audited, and replayed.

• Ingest — Connectors pull from document stores, databases, APIs, and sensor or enterprise feeds into secure processing pipelines.
• Structure — Extraction, normalization, and entity linking turn raw inputs into a coherent graph and schema-aligned records.
• Validate & Govern — Quality checks, jurisdiction or doctrine rules, and retention policies run before activation.
• Reason & Recommend — Models and rule engines score options with confidence, key evidence, and alternative courses of action.
• Act & Audit — Outputs reach APIs, RAG indexes, or operator consoles; every query, recommendation, and approval is logged.

3. Deployment models

Enterprise buyers choose where data and compute live. Synthium supports private cloud, dedicated VPC, and on-premises deployment. Customer operational content is not used to train foundation models.

• Canadian data residency available
• Role-based access control with least-privilege enforcement
• Full audit log of queries, outputs, and user actions
• Integration-first design — plugs into existing systems of record

4. API surface (reference)

Production API credentials and OpenAPI specs are issued to customers under enterprise agreements. The conceptual surface below describes how applications and agents interact with Synthium after a workspace is provisioned.

• POST /v1/ingest — Register a batch or stream of documents / records for processing (source URI, mime type, tenant scope).
• GET /v1/assets/{id} — Retrieve structured asset status, schema fields, validation results, and lineage.
• POST /v1/query — Semantic or filtered query over governed assets; returns answers with citations and provenance.
• POST /v1/embeddings — Request embeddings from approved corpora for private RAG workflows.
• POST /v1/recommend — Request scored recommendations with evidence packages and required human-approval flags.
• GET /v1/audit — Page audit events by time range, user, asset, or recommendation ID.

Authentication uses tenant-scoped API keys or OIDC client credentials. Rate limits, retention, and field-level redaction are configured per deployment. Contact sales for the current OpenAPI package and sandbox environment.

5. Operator decision support

For defence and industrial operations, Synthium presents recommendations with classification likelihoods, evidence summaries, risk assumptions, and doctrine or standards gates. Operators can accept, modify, or reject recommendations; alternate courses of action remain visible with scores.

This human-in-the-loop pattern is the same architecture used across regulated legal and enterprise document workflows — only the schemas, policies, and UI modules change.

6. Security & compliance posture

Security controls emphasize isolation, auditability, and procurement clarity for allied and enterprise buyers.

• No training on customer operational or matter data
• Encryption in transit and at rest in supported deployments
• Tenant isolation with configurable data residency
• Explainable outputs with provenance for oversight and after-action review
