Deployment Recommendations
| Status | Channels | Action |
|---|---|---|
| READY (18) | CH01-09, CH11-13, CH15, CH17, CH20-22, CH30 | Can deploy. Use per-channel optimal threshold from table above. |
| MARGINAL (3) | CH10, CH14, CH16 | CH10: AP jumped +27% but F1@0.32 still low (use t=0.005 for F1=0.958). CH14: AP dropped slightly (-5%), use t=0.17 for F1=0.896. CH16: AP +30% but still 0.854, needs more training data. |
