What if? — poke the model
drag a signal and the deployed models rescore this package live (implied signals move together — two years without a release also zeroes "releases, last 12mo"). The needle tracks the activity-collapse model, a logistic regression: monotone by construction, so it responds smoothly to counterfactuals where the tree models step.
maintainer activity collapse, 12mo
In plain words
- only 21% of recent issues get a response in 30 days
- healthy cadence: 73 releases in the last year
- active team: 13 people pushed in the last year

Probabilities are isotonic-calibrated on a held-out validation year and evaluated on future snapshots the models never saw (PR-AUC 0.894, precision@50 = 1.00 on the headline target).
