Epic: Protocol connection management and operator console

[smithaldon1]

Purpose

Build production-oriented, read-only protocol connection management for OPC-UA, MQTT, and BACnet, and reshape the Factory Intelligence Platform Workbench into a Demo-Factory-style operator console.

This supersedes the old live OPC-UA drift demo workstream. The new direction is broader: define protocol connections, test them safely, show connection health and tag/source mappings, and route configured source readings through the FactoryEvent ingestion path.

Acceptance Criteria

• Connection profiles can be defined for OPC-UA, MQTT, and BACnet.
• Secret and certificate values are referenced or redacted; raw secrets are not returned to the browser.
• Test-connection behavior is read-only and returns structured health/errors.
• Workbench uses an operator-console layout inspired by Demo-Factory: sidebar navigation, status strip, connections, protocol diagnostics, tag/source browser, and existing Sentinel workflows.
• Protocol adapters remain read-only by default and normalize source readings into FactoryEvents before Process Sentinel consumes them.
• Documentation explicitly states no industrial writeback, arbitrary tag writes, product disposition, QMS/MES writeback, or production-readiness claim.

Out of Scope

• Direct control of PLCs, DCS, SCADA, or equipment.
• Arbitrary tag writes.
• Product release/quarantine actions.
• QMS/MES writeback.
• Electronic signatures or validated production audit trails.
• Copying Demo-Factory code wholesale instead of using it as a UI/reference model.

Implementation Order

3. Connection profile API and storage.
4. Read-only test-connection API with redacted results.
5. Operator-console shell redesign.
6. Connections page.
7. OPC-UA adapter foundation.
8. MQTT adapter foundation.
9. BACnet adapter foundation.
10. Protocol Diagnostics page.
11. Tag/source browser.
12. Connector tests and docs.
