CANARY forecast · as of 2026-06
ec2
Activity-recency clocks + Contributor dynamics · Logistic Regression: the frozen champion fold model (oot_champion/fold_2025-11, trained on months before 2025-11, labels as known 2025-12) applied to the newest month of the panel. Inference only; no outcome for this month is known yet.
Read the rank, not the score. The score is the model's raw output and is not a probability: on the holdout the champion's mean score is about 0.5 against an observed advisory rate of 1 percent. Across the pre-registered holdout, reviewing the top fifth of plugins by this ranking caught about half of the advisories that followed.
Honest track record
Where ec2 ranked before each window
Activity-recency clocks + Contributor dynamics · Logistic Regression, embargoed rolling backtest: the rank this plugin held among every scored plugin at each forecast date, using only what was knowable then. Shaded months are the pre-registered holdout.
Scored at 32 forecast dates; on average in the top 11% of plugins (top 0.00% across the holdout). No advisory followed any of those dates within six months.
| Holdout month | Score | Rank | Share of panel | What followed |
|---|---|---|---|---|
| 2025-07 | 88.1% | 1 of 2,053 | top 0.00% | none within six months |
| 2025-08 | 88.7% | 1 of 2,053 | top 0.00% | none within six months |
| 2025-09 | 90.5% | 1 of 2,053 | top 0.00% | none within six months |
| 2025-10 | 91.5% | 1 of 2,053 | top 0.00% | none within six months |
| 2025-11 | 91.5% | 1 of 2,053 | top 0.00% | none within six months |

Key risk signals
- 4 prior advisory record(s) — history +8, recency +0 (0 within 90d, 0 within 365 days); component total +8 (cap 30).
- No advisory activity in the last 365 days — historical record only.
- Advisory severity (max CVSS 5.6 — Medium): +7 (cap 15).
- Latest release: 2026-07-20.
- Requires Jenkins core 2.479.3.
- Last commit: October 28, 2026 — live data from GitHub.
- Recent release activity supports active maintenance.
- 7 historical security warning(s) — none currently active.
- No SECURITY.md — vulnerability reporting process undocumented (+3).
- No Dependabot or GitHub Actions detected — limited automated maintenance (+3).
- Dependency risk: 3 of 12 dep(s) have advisories; worst: ssh-credentials (CVSS 6.5).
- Plugin health score 94/100 — acceptable maintenance posture.
