## Output Schema (JSON)

Agent output via `report_agent_job_result` (csv-wave tasks):

```json
{
  "id": "PROFILE-001",
  "status": "completed",
  "findings": "Found 3 CPU hotspots: O(n^2) in DataProcessor.processRecords (Critical), unoptimized regex in Validator.check (High), synchronous file reads in ConfigLoader (Medium). Memory baseline: 145MB peak, 2 potential leak sites.",
  "verdict": "",
  "artifacts_produced": "artifacts/baseline-metrics.json;artifacts/bottleneck-report.md",
  "error": ""
}
```

Interactive tasks output via structured text or JSON written to `interactive/{id}-result.json`.
