GET /ui/schema

Not an exact read, and deliberately so: it describes what the engine supports, which is a property of the build and the loaded stylesheet rather than of a committed state. There is nothing for ?at= to pin, and making an agent name a state to read the documentation would be a round trip to learn something that has not changed since startup. A document missing a key UiSchemaView::REQUIRED_KEYS promises is a 500 rather than a short answer. An agent that reads a support table with no properties concludes the engine supports no properties, and a wrong answer about what is supported is worse than no answer at all.

Example

curl "http://127.0.0.1:7700/ui/schema"

Start a server with argus run --serve; the port is --port (7700 by default). The request and response fields are in the query API guide.
