# Load Test Plan (Stage 4)

## Target
- 100 concurrent voice sessions
- 100 concurrent digital sessions
- Script entrypoint:
  - `python scripts/load_test.py --base-url http://localhost:8080 --voice 100 --digital 100`
  - or the profile-based equivalent:
    - `python scripts/load_test.py --base-url http://localhost:8080 --profile baseline_100_100`

## Metrics
- API error rate
- P95 response latency
- queue processing delay
- service availability during load

## Success criteria
- No critical errors
- Stable response times under threshold
- No data loss in interaction lifecycle
