refactor: use main in bernoulli/{mean,median,mode}/lib/index.js

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request renames the lib/index.js local variable that holds the require( './main.js' ) result from the function name to main in three outlier packages under @stdlib/stats/base/dists/bernoulli. Purely internal rename; no source, signature, JSDoc, test, or behavioral change.

Namespace summary

• Target: @stdlib/stats/base/dists/bernoulli
• Members analyzed: 13 (cdf, ctor, entropy, kurtosis, mean, median, mgf, mode, pmf, quantile, skewness, stdev, variance)
• Features with a clear majority (≥75%): file tree (12/13 outside ctor, which is a constructor class and legitimately omits the native-binding cluster), package.json top-level shape, directories, manifest.json keys (confs / fields / options), binding.gyp / include.gypi / src/main.c / src/addon.c / lib/native.js / examples/c/ / benchmark/c/ presence, the 10 shared keywords (stdlib, stdmath, statistics, stats, distribution, dist, bernoulli, binomial, discrete, univariate), README ## Usage / ## Examples / ## C APIs / ### Usage / ### Examples section sequence, lib/main.js validation prologue (isnan(p) || p < 0.0 || p > 1.0 → NaN), lib/main.js error construction (no errors thrown — all surface invalid input as NaN), JSDoc @param {Probability} p - success probability convention, and the var main = require( './main.js' ) lib/index.js entry-point convention (10/13 = 77% within bernoulli; 412/507 = 81% across @stdlib/stats/base/dists).
• Features without a clear majority (excluded): lib/factory.js presence (4/13, tracks whether the function takes a non-distribution argument — cdf, mgf, pmf, quantile); test/fixtures/julia/data.json (7/13, only the closed-form summary stats carry it); ## Notes README section (1/13 — mode/README.md has it because p = 0.5 legitimately needs a tie-break note); factory.js validation-prologue style (2 single-line vs. 2 stacked, no majority either way); 'parameter' keyword (8/13, tracks the summary-stat sub-cluster). Surfaced but intentionally deviating: ctor (constructor class, no native binding); stdev (delegates validation to variance; uses Python fixtures instead of Julia — porting the reference data is not mechanical and is out of scope).

@stdlib/stats/base/dists/bernoulli/mean

Renames the lib/index.js local-variable holding require( './main.js' ) from mean to main to match the namespace majority (10/13 = 77%) and the wider ecosystem (412/507 = 81% across @stdlib/stats/base/dists). The module.exports reference is updated correspondingly. JSDoc @example block — which intentionally uses var mean = require( '@stdlib/stats/base/dists/bernoulli/mean' ); to model consumer code — is left untouched.

@stdlib/stats/base/dists/bernoulli/median

Same rename, applied to lib/index.js of @stdlib/stats/base/dists/bernoulli/median. The variable in MODULES and the value passed to module.exports switch from median to main; the JSDoc @example block keeps the consumer-facing var median = require( '@stdlib/stats/base/dists/bernoulli/median' ); form.

@stdlib/stats/base/dists/bernoulli/mode

Same rename, applied to lib/index.js of @stdlib/stats/base/dists/bernoulli/mode. Variable in MODULES and module.exports switch from mode to main; consumer-facing @example block is untouched.

Validation

Checked:

• Structural feature extraction across all 13 members: file tree, package.json shape (top-level keys, scripts, directories, keywords, stdlib), manifest.json keys, README ## / ### heading set and sequence, lib/, src/, test/, benchmark/, examples/, docs/, binding.gyp, include.gypi, Makefile EOF conventions.
• Semantic feature extraction across all 13 lib/main.js, lib/index.js, and lib/factory.js (where present) files: public signature, return kind, validation prologue, error construction style, JSDoc tag set, require()-derived dependencies. Performed by direct file inspection rather than per-package agents — the namespace has 13 members and every lib/main.js follows the same isnan(p) || p < 0.0 || p > 1.0 → NaN prologue with no thrown errors, so the agent layer would not surface additional drift.
• Three-agent drift validation on the surviving correction. The lib/index.js variable name is a purely structural feature; Agent 1 (semantic-review) skipped per policy. Agent 2 (cross-reference): tests import via require( './../lib' ) and consume only module.exports; no test, example, or sibling package code references the local variable name. Agent 3 (structural-review): confirmed main as the convention via 77% within-namespace and 81% wider-stats/base/dists conformance.
• Cross-run dedup: searched open PRs (is:open bernoulli) and PRs merged in the last 14 days (is:merged bernoulli merged:>2026-06-13); none touch the three lib/index.js files modified here.

Deliberately excluded:

• ctor's missing native-binding cluster (binding.gyp, src/, include/, manifest.json, lib/native.js, examples/c/, benchmark/c/, test/test.native.js, ## C APIs README section). ctor is the distribution constructor class, not a math function; it has no C analog. Intentional deviation, not drift.
• stdev's Python vs. Julia test fixtures. All 11 other summary-stat packages use test/fixtures/julia/; stdev uses test/fixtures/python/. Porting the reference data requires re-generating it via Julia and rewriting the test loader — not a mechanical edit. Flagged for a future routine.
• stdev's missing validation prologue. stdev/lib/main.js is sqrt( variance( p ) ) and inherits NaN propagation from variance. Intentional delegation, not drift.
• lib/factory.js presence (4/13). Tracks whether the function takes a non-distribution argument (cdf, mgf, pmf, quantile); not a drift-correctable feature.
• mode's ## Notes README section. mode(0.5) is a legitimate tie between 0 and 1; the implementation returns 0 and the note documents that. Intentional content, not drift.

Disclosure

This PR was authored by Claude Code via the cross-package drift-detection routine. The target namespace @stdlib/stats/base/dists/bernoulli was selected by uniform-random pick over the 123 eligible directories (≥8 direct child packages with package.json under lib/node_modules/@stdlib/). Structural and semantic features were extracted from all 13 members, majority patterns were computed at the 75% conformance threshold, and the surviving correction was validated against the namespace, the wider stats/base/dists ecosystem, and open/recent PRs before any file was edited. Each rename is a two-line in-file substitution; no source behavior, JSDoc, test, or generator output is touched.
