Backend:
- Re-add --out json=- but properly route: JSON lines → metric
aggregation, non-JSON lines → text log (summary text lands in log)
- Aggregate http_req_duration / http_reqs / http_req_failed / checks
per test into live state (capped 50k samples)
- Broadcast { metrics: {...} } SSE events every second with
score, checksRate, httpOkRate, p90/p95/p99, req/s etc.
- computeScore() composite 0-100 based on p95 + error rate
Frontend:
- 3 animated SVG ring gauges: Score (/100), Checks OK (%), HTTP OK (%)
- Smooth CSS transition on stroke-dashoffset (0.7s cubic-bezier)
- Pulse animation while test is live, stops on completion
- Color: green ≥90/98/99, yellow mid-range, red below thresholds
- Stats strip: Requests, Req/s, Avg, p(90), p(95), p(99)
- p(95) cell color-coded green/yellow/red vs latency
- Threshold pass/fail banner at bottom of gauges panel
- Raw output collapsed in <details> by default
- History items show mini score ring gauge (44px) inline
- History detail expands 3 medium gauges + stat grid
