collabSupport/tests/voiceDiagRenderer.test.js

// Unit tests for services/renderers/voiceDiagRenderer.js. Renderer
// is pure — no I/O — so the tests just assert on the produced
// markdown string. The interesting cases are:
//
//   - severity buckets appear in the right order
//   - the OK bucket is hidden by default and shown under `detailed`
//   - the fixable-issues footer counts and lists only remediable
//     results (an OK check with a remediation still doesn't count,
//     since we filter status !== 'ok')
//   - the details block is only rendered under `detailed`
//   - empty result list yields a benign single-line message
