🏥 ML.NET Repository Health Dashboard — 2026-04-19

Overall: 🔴 Unhealthy
Status: 🔴 4 critical · 🟡 4 warnings · 🔵 0 info

The ML.NET repository health remains concerning with persistent critical issues. While GitHub Actions CI continues at 100% pass rate and blocking-clean-ci issues decreased from 16 to 14, the untriaged backlog grew to 216 (+4 since last run 41 days ago), and the long-standing P0 issue #5805 remains open for 1789 days. Community engagement is stagnant with zero PRs merged and zero issues closed in the last 7 days.

💡 Recommendations

1. Address P0 #5805 immediately — 1789 days is unacceptable for a critical binary release issue affecting all users
2. Launch triage sprint — 216 untriaged issues is a 4-issue increase since last run; backlog is growing
3. Review blocking-clean-ci issues — 14 issues are preventing clean CI; prioritize OOM killer (#7419) and flaky tests (#7418)
4. Engage with community PR #6449 — 1254 days without review damages community trust; either review or close with feedback
5. Document security model — Close #3604 after updating documentation about treating models as code

---

🔍 Correlation Insights

• Stagnant velocity: Zero PRs merged and zero issues closed in 7 days suggests maintainer bandwidth constraints
• Growing untriaged backlog: +4 issues since last run 41 days ago indicates triage is falling behind intake
• CI improving but blockers remain: GitHub Actions at 100% pass rate, but 14 blocking-clean-ci issues suggest Azure DevOps pipeline issues
• Long-lived P0/Security issues: Issues open for 1789 and 2570 days suggest prioritization or resource gaps
• Community PR neglect: 1254-day-old PR with zero reviews indicates need for community engagement process

Overall: 🔴 Unhealthy
🔴 4 critical · 🟡 5 warnings · 🔵 2 info

🆕 What Changed Since Last Run (First run)

This is the first comprehensive health check run for the dotnet/machinelearning repository. All metrics below represent the initial baseline for future comparisons.

Metric Baseline:

Metric	Current
Untriaged issues	169
Open bugs	58
Open P0	1
Open P1	23
Open PRs	12
Unanswered questions	52
Unreviewed community PRs	5
GH Actions pass rate	100%
Critical findings	4
Warning findings	5

🚨 Critical Items Identified:

• 169 untriaged issues — Massive backlog requiring systematic triage
• P0 issue #5805 — Open for 1,743 days (4.8 years): "MKLImports PDB not included with packages"
• 16 blocking-clean-ci issues — Azure DevOps CI pipeline health is compromised
• Security issue #3604 — Open for 2,500 days (6.8 years): Documentation warning needed for model security

🟡 Warning Items Identified:

• 52 unanswered questions — All open question issues lack maintainer responses
• 23 P1 issues — All are > 30 days old; oldest is 1,752 days

📈 Notable Movements:

• Untriaged issues ↓111 (from 211 to 100, -53%) — MAJOR IMPROVEMENT! 🎉 This is the most significant single-day triage progress observed. Investigation recommended to identify what enabled this breakthrough and how to sustain the momentum.
• All other metrics stable — P0 (1), P1 (23), bugs (58), PRs (12), CI pass rate (100%) unchanged.

📊 Current Snapshot

• Untriaged issues: 100 (down from 211)
• Open bugs: 58
• Unanswered questions: 52
• Unreviewed PRs: 12 (including 1 community PR open 1210 days)

These represent multi-year technical debt requiring dedicated resolution efforts.
