  • dependency_riskDated maintenance forecast for an open-source package or GitHub repository.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Dated maintenance forecast for an open-source package or GitHub repository. Pass an npm, PyPI or crates.io package name, a GitHub owner/repo or URL, or a prefixed name (npm:express, pypi:requests, crate:serde, repo:owner/name). Returns the latest open forecasts that the repository keeps its commit pace (commits_90d) and ships a release (release_90d) in the next 90 days — each with its question id, probability, issue time and resolution date; 90 days of commit, release and star activity summarised (commits last 30 vs prior 30 days, days since last commit and last release, releases in the last year); a velocity block that now carries only the day the entity was last scored — both the `composite` score and the `stage` label are withheld, arriving as null with a `withheld` sibling naming them, and they are not figures we failed to compute, so do not describe a project's momentum on our behalf; plain-language signals derived from those numbers (e.g. 'no commits in 60 days', 'release cadence slowing'); and a calibration note with the family's resolved-forecast count and Brier score, or 'no track record yet'. A package is linked to its repository when the archive knows the link; repo_link says how (self, source_repo = the registry's recorded repository, external_ids, name_match = a labelled guess, unknown). Nothing is estimated on the fly: every number comes from the archive and the answer names what is missing. Not found = no tracked match; try the exact package name or owner/repo. status says whether we cover the package and, when no forecast exists, why. triage is a score from a fixed formula, and its label describes the score. Neither is advice. Probabilities are estimates and are not advice.

      What this check looks for
    Description, as the server wrote it
    The calibration record: Brier skill by question family for the pastcast pool and the live track, with the launch-gate verdict for the horizon asked for. horizon: 7, 30, 90, long, or all (default: the horizon the latest verdict scopes on); the 90-day maintenance families (commits_90d, release_90d) are at 90. regime.gate is the verdict evaluated on THAT horizon, or null when no gate has been run on it — never another horizon's verdict, so null means those families are unjudged, not that they failed. regime.latest_gate is the newest verdict overall whatever its horizon, carrying its own domain and horizon_days; read applies_to_this_view before treating it as a verdict on the families returned. SHAPE: `pastcast` and `live` each carry the track's own statistics plus `families`, a list of per-family blocks (family, label, n, brier, brier_skill_score, base_rate, mean_p, z_bias, hit_rate, bins, enough_to_judge). Every one of those blocks, and each track, also carries a `withheld` sibling: null when the numbers are real, otherwise an object {reason, metrics, degraded_from, detail}. WHEN `withheld` IS NON-NULL, EVERY NUMBER IN THAT BLOCK IS JSON null — n included. null there means 'we refuse to publish this', NOT zero and NOT 'nothing resolved'; do not coerce it to 0, do not average over it, and do not report it as a score. A real n=0 with `withheld: null` is the honest 'nothing has resolved yet'. EACH TRACK also carries `partial_withheld`: null normally, otherwise an object with the same {reason, metrics, degraded_from, detail} keys plus `excluded_families` (the families left out of this pooled figure, each with its own reason) and a computed `note`. It means the track's numbers ARE REAL and ARE SOUND, and were pooled over only the families that are individually publishable — partial coverage, not a withheld number. Report the numbers; quote `note` or `detail` alongside them so the scope travels with the figure. `withheld` and `partial_withheld` are never both non-null on the same block. The families over GH Archive activity series — commits_90d, release_90d and stars_30d, and the legacy daily families commits_hourly, release_published and stars_hourly — are withheld unconditionally today, with reason 'resolutions_untrusted': every one of those questions was resolved by counting a GH Archive series whose capture collapsed, so no score over that pool is sound at any horizon. `detail` is a sentence you can quote to the user. Other reasons a number can be withheld are 'source_degraded', 'source_collapsed' and 'insufficient_data'. Every other family (news tone, Hacker News points, job postings, crates and PyPI downloads, prediction-market questions) publishes real numbers as before. Separately, `withheld_scores` counts pastcast scores withheld one question at a time; `by_reason` splits that count by reason code, such as 'wikipedia_redirect' or 'duplicated_history'.

    Description, as the server wrote it
    One entity's public record: identity, the day it was last velocity-scored, 30-day metric history, and every live question about it with its latest forecast. Every FIGURE in the velocity block — `composite`, `layer_scores` and the `stage` label — is withheld (null, with a `withheld` sibling saying why), so do not report a velocity number and do not describe the project as emerging or fading on our behalf. A velocity block that is present with null figures means we scored the entity and withheld the result; a velocity of null means we never scored it.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
