chore: align keywords with sibling stdev packages

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request corrects a copy-paste defect in the keywords array of stats/base/dists/discrete-uniform/stdev/package.json so the package is discoverable by its actual function.

Namespace summary

• Namespace: stats/base/dists/discrete-uniform (14 members: cdf, ctor, entropy, kurtosis, logcdf, logpmf, mean, median, mgf, pmf, quantile, skewness, stdev, variance).
• Features analyzed: file tree, package.json shape (keys, scripts, stdlib, keywords), README section list and order, manifest.json shape, test/benchmark/example file naming, public signature, validation prologue, JSDoc shape, error construction, dependencies.
• Features with a clear majority (≥75% within the namespace): file tree (excluding ctor and skewness/julia-fixtures deviations, both intentional), package.json top-level key set, README section list, validation-prologue patterns within each call-shape group, errorConstruction (none of the moment/density functions throw), returnKind.
• Features without a clear majority (excluded from drift analysis): the lib/factory.js / test/test.factory.js / test/test.<fn>.js cluster (6/14 = 43%); @returns JSDoc tag type for moment functions ({number} 5/7 vs {PositiveNumber} 2/7 = 71%, below threshold).

discrete-uniform/stdev

Replace "variance" with "standard", "deviation", "stdev", and "std" in the keywords array of package.json, and reorder the dispersion block to match sibling stdev packages. The previous keywords were a byte-identical copy of discrete-uniform/variance, making the package undiscoverable by its actual function. All 9/9 sampled sibling stdev packages include these four terms; 0/9 include "variance".

Validation

• Structural extraction over all 14 members: file tree (excluding node_modules/), package.json shape, README headings, manifest.json shape, test/benchmark/example filenames.
• Semantic extraction over lib/main.js for each member: public signature, validation prologue, return kind, error construction, JSDoc shape, dependencies. Group-A (moment) and Group-B (function-of-x) members each form an internally consistent cohort; ctor is a distinct constructor cohort.
• Three-agent drift validation on the single candidate correction:
  • Semantic (Opus): confirmed-drift — the keyword list is byte-identical to discrete-uniform/variance/package.json; the source, README, and description describe standard deviation only, so "variance" is an unintentional copy-paste.
  • Cross-reference (Opus): confirmed-drift — keywords is not read by any test, REPL fixture, or namespace export; replacing it breaks no observable contract.
  • Structural (Sonnet): confirmed-drift — all 9/9 sampled sibling stdev packages use standard, deviation, stdev, std and none uses variance.
• Deliberately excluded:
  • ctor deviations on file tree, README section list, and package.json shape — ctor is a class constructor, not a numeric function; the deviation reflects a genuine semantic difference.
  • skewness lack of test/fixtures/julia/ — the function is the constant 0.0 for all valid inputs, so there is no parameter sweep to validate against Julia.
  • stdev and variance use of @returns {PositiveNumber} (vs {number} in the other five moment packages) — 5/7 = 71%, below the 75% threshold; excluded as no clear majority.

Disclosure

This PR was produced by Claude Code running a cross-package drift-detection routine. The routine picked the namespace via a recorded random seed, extracted structural and semantic features across all 14 members, computed per-feature majority patterns at a 75% threshold, ran a three-agent validation pass (two Opus, one Sonnet) over the single surviving candidate correction, and shipped only the change confirmed by all three agents. The PR is being opened as a draft for human audit; please do not promote to ready-for-review until the change has been confirmed.
