/**
 * Smoke tests for GET /live-events/:topic — primarily the topic
 * grammar. The full streaming path needs a live DB (read-gate), so we
 * focus on:
 *   - 400 on invalid topics (single-letter, missing kind, bad chars)
 *   - non-400 on the valid forms (single-segment `kind:id`, multi-
 *     segment `kind:id:scope1:scope2`).
 *
 * The route uses softAuth; no cookie required.
