## Core Metrics
- leads_processed: ${metrics.leads_processed || 0}

- drafted_count: ${metrics.drafted_count || 0}
- reply_drafts_count: ${metrics.reply_drafts_count || 0}
- replied_count: ${metrics.replied_count || 0}
- rejected_count: ${metrics.rejected_count || 0}
- score3_conversion_count: ${metrics.score3_conversion_count || 0}
- score3_conversion_rate: ${conversionRate}%

## System Timestamps
- last_lead_filter_run: ${state.lastLeadFilterRunAt || "n/a"}
- last_draft_run: ${state.lastDraftRunAt || "n/a"}
- last_reply_run: ${state.lastReplyRunAt || "n/a"}
- last_successful_run: ${state.lastSuccessfulRunAt || "n/a"}

## Notes
- Use this report in /campaign-retro for lever diagnosis.
- If drafted_count grows but replied_count stays flat, focus on voice and signal quality.
