+# Triage Cadence Report — timmy-home (2026-04-15)
+
+> Issue #685 | Backlog reduced from 220 to 50
+
+## Summary
+
+timmy-home's open issue count dropped from 220 (peak) to 50 through batch-pipeline codebase genome generation and triage. This report documents the triage cadence needed to maintain a healthy backlog.
+
+## Current State (verified live)
+
+| Metric | Value |
+|--------|-------|
+| Total open issues | 50 |
+| Unassigned | 21 |
+| Unlabeled | 21 |
+| Batch-pipeline issues | 19 |
+| Issues with open PRs | 30+ |
+
+## Triage Cadence
+
+### Daily (5 min)
+- Check for new issues — assign labels and owner
+- Close stale batch-pipeline issues older than 7 days
+- Verify open PRs match their issues
+
+### Weekly (15 min)
+- Full backlog sweep: triage all unassigned issues
+- Close duplicates and outdated issues
+- Label all unlabeled issues
+- Review batch-pipeline queue
+
+### Monthly (30 min)
+- Audit issue-to-PR ratio (target: <2:1)
+- Archive completed batch-pipeline issues
+- Generate backlog health report
+
+## Remaining Work
+
+| Category | Count | Action |
+|----------|-------|--------|
+| Batch-pipeline genomes | 19 | Close those with completed GENOME.md PRs |
+| Unassigned | 21 | Assign or close |
+| Unlabeled | 21 | Add labels |
+| No PR | ~20 | Triage or close |
+
+## Recommended Labels
+
+- `batch-pipeline` — Auto-generated pipeline issues
+- `genome` — Codebase genome analysis
+- `ops` — Operations/infrastructure
+- `documentation` — Docs and reports
+- `triage` — Needs triage
