/**
 * ADR-0063-A §P3 — query_inflight_paused MCP wrapper tests.
 *
 * Mocks dbAll() and asserts the wrapper builds the right scope filter,
 * shapes the response, and degrades gracefully when no rows match.
 * Source-of-truth for the SQL stays in SystemTableService.queryInflightRuns;
 * tests here cover the handler-level contract:
 *   - admin=true is honoured ONLY when context.spaceId === 1 (otherwise dropped)
 *   - non-admin callers stay scoped to their context.spaceId via metadata.space_id
 *   - agent_slug + conversation_id filters propagate to the SQL WHERE clause
 *   - limit capped at 200, default 50
 *   - empty result + DB error shapes
