🏥 ML.NET Repository Health Dashboard — 2026-03-26

Overall: 🟢 Healthy
Status: 🔴 2 critical · 🟡 4 warnings · 🔵 0 info

The dotnet/machinelearning repository shows significant improvement since the March 9 baseline. Major win: Untriaged backlog reduced from 212→100 issues (-53% reduction). PR merge activity remains strong (4 merged in last 7 days). However, persistent challenges remain: a 4.8-year-old P0 issue (#5805), 16 blocking CI issues, and 52 unanswered questions requiring maintainer attention.

---

🚨 Maintainer Action Required

Immediate (🔴 Critical)

• P0 Issue (#5805) — MKLImports PDB not included with packages open for 1,765 days (4.8 years). Needs resolution or priority downgrade.
• Security Issue (#3604) — Documentation warning: models = code open 2,525 days. Security documentation gap.

Timely (🟡 Warning)

• Untriaged Backlog (100) — Down from 212 on Mar 9 (-53% ✅), still above 20-issue threshold
• Unanswered Questions (52) — Same as March 9, question-labeled issues >7 days old with no maintainer response
• P1 Backlog (23) — Stable count, same as March 9
• Blocking CI Issues (16) — blocking-clean-ci label preventing clean builds

💡 Recommendations

1. Celebrate Triage Progress — Untriaged count reduced from 212 to 100 (-53%). Continue momentum to reach <20 target.
2. P0 Resolution or Downgrade — Either fix #5805 (MKL PDB issue) or downgrade priority with documented justification. 1,765 days is untenable for P0.
3. Community PR Hygiene — Review or close ancient PR #6449 (1,229 days with zero reviews). Provide closure after 3+ years.
4. CI Health Restoration — Address 16 blocking-clean-ci issues. Prioritize #7419 (OOM killer).
5. Question Response Campaign — Triage 52 unanswered questions; bulk-close stale questions, respond to recent ones.

---

🔍 Correlation Insights

• Triage momentum: Untriaged issues dropped from 212 → 100 (-53% reduction), showing strong cleanup effort since March 9
• Development velocity positive: 4 PRs merged this week vs 1 last week; PR backlog shrinking (13→10 open)
• Issue closure improving: 6 issues closed in last 7 days (vs 0 on March 9)
• CI infrastructure concern: 16 blocking-clean-ci issues remain stable; Inclusive Heat Sensor workflow at 0% pass rate
• Ancient P0 paradox: P0 issue open 1,765 days suggests priority misclassification or resource constraints
• Community engagement gap: Ancient PR #6449 (1,229 days) with zero reviews indicates bandwidth limitations

📋 Health Check — 2026-03-04

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
• 5 community PRs awaiting review — Oldest is 1,208 days old
• 4 issues awaiting user input with new activity — Users have replied and need follow-up
• 6 stale PRs — Half of all open PRs are > 90 days old

📈 Notable Observations:

• Zero activity in last 7 days (0 issues opened/closed, 0 PRs merged) — may indicate maintenance pause or data anomaly
• GitHub Actions workflows are healthy (100% pass rate), but Azure DevOps has significant issues
• Large accumulated technical debt: P0 open 4.8 years, security issue 6.8 years, oldest community PR 3.3 years

📊 Current Snapshot

• Untriaged issues: 169
• Open bugs: 58
• Unanswered questions: 52
• Unreviewed PRs: 12 (5 community)
• CI status: ✅ GH Actions (100%) / 🔴 AzDO (16 blocking issues)

🆕 First Run — Baseline Established

This is the first run of the ML.NET Repository Health Check. All metrics below represent the initial baseline. Future runs will compare against these values to show trends and deltas.

Current Snapshot:

• Untriaged issues: 100 (🔴 above threshold of 50)
• Open bugs: 58
• Open P0: 1 (issue #5805, 1752 days old)
• Open P1: 23 (many >1000 days old)
• Open PRs: 12
• Unanswered questions (>7d): 52 (🔴 above threshold of 15)
• Community PRs awaiting review: 5 (including #6449 at 1208 days)
• CI status: 🟢 GH Actions (100% pass rate) / 🟢 AzDO (no blocking issues)

🔴 Critical Items Identified:

1. P0 Issue Open 1752 Days: #5805 — MKLImports PDB not included with packages
2. Large Untriaged Backlog: 100 issues need triage (threshold: 50)
3. Stale Community PRs: Multiple PRs awaiting maintainer review for 700+ days

🟡 Warnings:

• 52 unanswered questions >7 days old (threshold: 15)
• 23 P1 issues open (many very old)
• 1 open security issue (#3604, documentation gap)
• 5 PRs open >90 days

Key Insight: Repository shows excellent CI health but significant maintainer bandwidth constraints for community engagement. Triage sprint and community PR review session recommended.

📈 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)
• CI status: ✅ GH Actions (100% pass, 0 failures in 24h) / 🔴 AzDO (16 blocking-clean-ci issues)
• Community items awaiting response: 0 (no recent user replies to "Awaiting User Input")

Key Context: While the untriaged backlog saw dramatic improvement, the four long-standing critical issues persist unchanged: P0 #5805 (1746 days), 16 blocking-clean-ci issues, stale community PR #6449 (1210 days), and security issue #3604 (2505 days). These represent multi-year technical debt requiring dedicated resolution efforts.
