A private research copilot built around governed evidence.
A reference design for turning approved policy, research, and client material into a private assistant with a controlled data path.

THE CHALLENGE
The operating constraint.
Analysts spent significant time locating approved information and validating whether a generated response was supported by the right policy version. Public model endpoints did not satisfy the team’s data and access requirements.
THE SPARK SYSTEMModel, platform, and capacity—designed together.
SPARK deployed a customer-adapted Atlas release on isolated capacity, added document-level entitlements to retrieval, and enforced answer citations, model-version traceability, and controlled retention at the serving layer.
SOLUTION ARCHITECTUREOne traceable path
01 02 03 04
One traceable path
from signal to decision.
Private retrieval
Search and reranking execute inside the customer-specific data and network boundary.
Controlled generation
The private model release answers only when evidence and policy checks meet threshold.
Audit record
Prompt metadata, source versions, model version, and policy decisions are recorded for review.
DELIVERYFrom baseline
From baseline
to controlled production.
Boundary design
Mapped data classes, retention rules, user entitlements, and prohibited model paths.
Private adaptation
Created a specialist release using approved examples and an evidence-focused evaluation suite.
Acceptance and rollout
Validated source fidelity with reviewers before staged access across analyst teams.
“Acceptance depends on source fidelity, permission enforcement, refusal behavior, and reviewer sign-off on a disclosed evaluation set.”SOLUTION DESIGN PRINCIPLE · NOT A CUSTOMER TESTIMONIAL
