?? Self-Service EVA Domain Assistant Accelerator Program

Explore generative AI ? on your schedule, with your goals, and your budget.

The Artificial Intelligence Centre of Enablement (AICoE) is proud to announce the launch of the Self-Service EVA Domain Assistant Accelerator Program, a next-generation pilot that puts business teams in control of their AI journey. This program builds on the success of EVA DA and introduces workspace-style booking, goal-driven evaluation, and cost recovery options ? all designed to make AI exploration intuitive, measurable, and scalable.

?? What's New?

??? EVA DA Booking Portal

Inspired by Archibus, users can now reserve EVA DA environments just like booking office space:

• Choose from specialized AI workspaces (e.g., Protected B, OCR-enabled, translation-focused).
• Set recurring access for sprint reviews, onboarding, or training.
• View availability and usage history.

?? Role-Based Access

EVA DA supports secure, role-based access:

Role	Permissions
Reader	View-only access
Contributor	Upload and manage documents
Admin	Configure environments and manage team access

?? Entry & Exit Surveys

To ensure meaningful outcomes, each EVA DA "rental" includes:

? Entry Survey ? Before starting, clients define:

• The use case they want to explore.
• Expected benefits, outcomes, and target metrics.
• Any specific AI features or document types they plan to use.

?? Exit Survey ? At the end of the rental period, clients report:

• Actual results achieved.
• Lessons learned and blockers encountered.
• Suggestions for future improvements.

These insights continuously improve EVA DA and tailor future AI services to real business needs.

?? Cost Recovery & Funding

To support sustainable scaling, EVA DA now includes a cost recovery model:

• Clients provide accounting information during onboarding.
• The business receives a receipt for funding once the rental is complete.
• Flexible usage plans available:
  • Blocked time ? e.g., 2-week sprint access
  • Model-specific environments ? e.g., OCR, translation, summarization
  • Team-based quotas ? for document uploads and queries

?? Why It Matters

This program empowers business teams to:

• Explore AI use cases independently.
• Measure impact and ROI.
• Scale adoption with minimal technical overhead.

It reflects leadership's vision for secure, scalable, and self-directed AI access ? and it's ready for your team.

?? Ready to Get Started?

2. Book your EVA DA space
3. Define your goals and start exploring

?? AI Assistant (EVA Brain v2)

The AI Assistant tab (src/components/AIAssistant.tsx) connects live to EVA Brain v2:

• Health ping on mount ? shows Brain Online / Brain Offline badge via pingBrain()
• Offline graceful degradation ? warning banner + disabled input when brain is unreachable
• Conversation history ? full chat history passed on every chatUngrounded() call
• 5 starter chips ? contextual suggestions shown on empty conversation

Brain Client (src/lib/brain-client.ts)

Base URL:  VITE_BRAIN_BASE_URL env var  (default: /api/brain  ? Vite proxy ? http://localhost:8001)
Endpoints: POST /v1/chat/ungrounded   (chatUngrounded)
           POST /v1/chat              (chatGrounded ? RAG)
           GET  /v1/health            (pingBrain)

Mandatory headers sent on every request:

Header	Value
X-Actor-OID	dev-user (dev) / authenticated OID (prod)
X-Correlation-ID	crypto.randomUUID() per request
X-Caller-App	accelerator
X-Environment	dev / prod

?? Local Development

# Install dependencies
npm install

# Start dev server (port 5173 ? proxies /api/brain ? http://localhost:8001)
npm run dev

# Type-check + production build (quality gate)
npm run build

# Preview production bundle
npm run preview

EVA Brain v2 must be running on port 8001 for the AI Assistant tab to connect. The Vite dev server auto-proxies /api/brain/* ? http://localhost:8001. Without brain, the app loads normally with an "Offline" badge in the AI tab.

Environment Variables

Variable	Default	Description
VITE_BRAIN_BASE_URL	/api/brain	Override brain API base URL (e.g. for prod)

? Quality Gates

Check	Command	Status
Type check + build	npm run build	? Passes
Lint	npm run lint	? Passes
EVA Brain proxy	npm run dev ? /api/brain/v1/health	Requires Brain v2 on port 8001
