GraphiQL explorer

The explorer lets you read the schema and try a query or mutation by hand before your agent sends it. Open $RYSTIC_URL/_rystic/graphiql in a browser:

curl -s -o /dev/null -w '%{http_code}\n' "$RYSTIC_URL/_rystic/graphiql"
# -> 200

The explorer is GraphiQL over Linear’s schema trimmed to the queries and mutations the simulator serves, so a field it hides is one the simulator would refuse. The explorer sends no key of its own, so a first query answers 401 until you open the Headers pane under the query editor and enter {"Authorization": "lin_placeholder"}. Each query you run then goes to POST /graphql on the simulator, lands in its state and takes the next id and the simulator’s clock. The state UI at $RYSTIC_URL/_rystic/ui links to the explorer from its header.
