AI Task Fail Rate Dashboard - Current 85% → Target <20%

# AI Task Fail Rate Dashboard\n\n## Current Metrics (as of 2026-04-29)\n- **Total Tasks**: 729\n- **Completed**: 106 (14.5%)\n- **Failed**: 333 (45.7%)\n- **Proposed/Pending**: 275 (37.7%)\n- **Overall Fail Rate**: 85.5%\n\n## Top Failure Reasons\n1. \"No available distributed workers\" - 204 tasks (61% of fails)\n2. \"gatewayAvailable is not defined\" - 109 tasks (33% of fails)\n3. Restart recoveries - 20 tasks\n\n## Daily Fail Rates (Last 10 Days, Descending)\n| Date | Total | Completed | Fail Rate |\n|------|-------|-----------|-----------|\n| 2026-04-29 | 308 | 18 | 94.2% |\n| 2026-04-27 | 55 | 46 | 16.4% |\n| 2026-04-26 | 42 | 21 | 50.0% |\n| 2026-04-25 | 46 | 1 | 97.8% |\n| ... | ... | ... | ... |\n\n## Milestone #2 Plan\n- **Retry Logic**: Exponential backoff (30s → 1m → 2m → max 30m), max 3 retries for worker/gateway errors.\n- **Target**: <20% fail rate\n- **Next**: KPI regression, simulation validation by data science.\n\nServices healthy. Progress tracked.
