Steps
GET /vui/platforms/:platform/historians to list installed historians by their VIP identity
GET /vui/platforms/:platform/historians/:historian to confirm the historian exposes a topics sub-route
GET /vui/platforms/:platform/historians/:historian/topics/:topic with a partial topic to discover sub-topics, or a full topic (or read-all=true) to retrieve data
Add start/end datetime bounds plus skip/count for pagination and order=FIRST_TO_LAST or LAST_TO_FIRST to control result ordering
Use the tag or regex query parameters to filter which topics are returned (tag requires the tagging service to be running and configured)
Known gotchas
Metadata (units, type, timezone) is only included in the response when querying a single topic - multi-topic queries omit the metadata field entirely
regex must follow Python re syntax and be URL-encoded in the query string
All historian endpoints require a valid JWT BEARER token from /authenticate - an invalid or missing token returns 401 before the query is evaluated
