docs: propagate description and example fixes in stats/base/dists/*

[Planeshifter]

Propagating fixes merged to develop between 2026-05-13 20:52 PDT (360877d) and 2026-05-14 02:11 PDT (80b1ef7) to sibling packages.

Description

stats/base/dists/{gamma,pareto-type1}/pdf

Propagates the double-space collapse from 4728aa8 to two additional package.json description fields that contain the same defect: an errant double space between the distribution name and the word "distribution". Both packages are updated to be consistent with the fix applied in the source commit.

• lib/node_modules/@stdlib/stats/base/dists/gamma/pdf
• lib/node_modules/@stdlib/stats/base/dists/pareto-type1/pdf

stats/base/dists/{lognormal,rayleigh}/*

Propagates the sigma lower-bound fix from 3220a54 to 17 sibling C example files. Prior to that fix, sigma was generated from [0.0, upper], allowing a value of 0.0 which falls outside the strictly-positive support required by both lognormal and rayleigh distributions; the lower bound is raised to 0.1 to guarantee a valid scale parameter.

• lognormal/{mode,variance,skewness,mean,stdev,entropy,median}
• rayleigh/{pdf,mode,variance,kurtosis,cdf,mean,entropy,logcdf,logpdf,median}

stats/base/dists/{discrete-uniform,pareto-type1}/logcdf

Propagates the description normalization from f2c2f39 to two sibling logcdf packages, aligning the README tagline, JSDoc @module summary, and package.json description to the canonical form "<DistName> distribution logarithm of cumulative distribution function (CDF).". As a side effect, this fixes the pre-existing CDF)for missing-space typo in both package.json files.

Validation

Audited the 24-hour window (360877d..80b1ef7, 15 first-parent commits) for propagable fix patterns. Three patterns surfaced: the double-space collapse from 4728aa8, the sigma lower-bound fix from 3220a54, and the logcdf description normalization from f2c2f39. Search was scoped to sibling packages under stats/base/dists/*. Two independent validators read each candidate site in full and confirmed the defect; an adaptation pass produced per-site patches for the description-normalization pattern; a style-consistency pass reviewed each proposed patch.

Items deliberately excluded:

• Four logcdf packages (t, normal, lognormal, kumaraswamy) where the source rewrite is not a clean substitution — t/logcdf and kumaraswamy/logcdf introduce extra phrasing ("(CDF)" parenthetical, leading "Evaluate" verb), and normal/logcdf / lognormal/logcdf READMEs do not wrap "cumulative distribution function" in a reference link. Flagged for human review by the validation pass.
• Sigma-bound propagation to non-positive-scale distributions (no sites — normal was the source; lognormal and rayleigh are the only siblings whose C examples generate sigma = random_uniform( 0.0, ... )).
• The numpy.nans keyword removal from 65cbb12 — no sibling package.json files reference numpy.nans.
• Source commits classified as feature additions (feat:), namespace/ToC updates, or chores touching only package.json keywords (00769bf) — none carry a propagable defect pattern.

Disclosure

This PR was authored by Claude Code as part of an automated daily propagation pass over commits merged to develop. Each propagation site was independently verified by two validators reading the target file in full, an adaptation pass produced per-site patches where the source fix was not verbatim-applicable, and a style-consistency pass reviewed the resulting changes before they were applied. The PR is being opened as a draft for human audit; please do not promote to ready-for-review until the changes have been confirmed.

I am not wholly convinced that this is actually a better/preferred description practice. It reads more awkwardly than what we had before.

[kgryte]

I think this is based on "Discrete uniform distribution cumulative distribution function" which does read fine. Once you start throwing in other qualifiers, it starts straining the English language, making an awkward construction.
