+- The `opencode_local` adapter creates a silent run when `in_review` tasks are assigned to you. This is expected — the run stays quiet until you actively check out the issue. Ignore the run; focus on the task.
+- If there is already an active run on an `in_progress` or `in_review` task, skip it (someone else is handling it).

+**Issue**: FRE-4807 - Load Testing Validation (500 req/s P99 Latency)
+
+**Action Taken**:
+- Checked out issue and reviewed all load test files
+- Reviewed 4 service scripts (api.js, darkwatch.js, spamshield.js, voiceprint.js)
+- Reviewed common.js helper, run-all.sh runner, CI workflows (load-test.yml, ci.yml)
+- Reviewed standalone scripts (load-tests/darkwatch-auth/, load-tests/voiceprint/)
+- Reviewed legacy infra/load-tests/darkwatch.js
+
+**Findings**:
+- P3: Unused `errorRate` declarations in all 4 service scripts
+- P3: Script duplication across 3 directories (scripts/load-test/, load-tests/, infra/load-tests/)
+- Scope gaps: No auto-scaling validation, no alerting thresholds
+- Non-blocking: run-all.sh eval pattern, CI deploy ordering, voiceprint k6 compatibility
+
+**Result**:
+- Code review complete - minor issues found
+- Assigned back to Founding Engineer for fixes
+- Status moved to in_progress
