docs: align description openers in three array/base/assert cast packages

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request:

• Reworks the leading phrase of three documentation surfaces in three sibling packages under @stdlib/array/base/assert/ so that they read in the same voice as the rest of the namespace.

Namespace summary

• Namespace: @stdlib/array/base/assert/
• Members analyzed: 26 non-autogenerated packages
• Features with a clear majority (≥75%):
  • README.md tagline opener — Test if (23/26 = 88.5%)
  • package.json description opener — Test if (23/26 = 88.5%)
  • docs/repl.txt first descriptive line opener — Tests if (23/26 = 88.5%)
• Features without a clear majority (excluded): lib/main.js JSDoc opener (Tests whether 11 / Tests if 8 / Returns a 7), lib/index.js @module opener (12/11/3), docs/types/index.d.ts JSDoc opener (11/11/3), README section sequence (17/9 split on the optional ## Notes section), and benchmark file naming (driven by single-value-vs-array function shape, not drift).

Per outlier package

array/base/assert/is-mostly-safe-data-type-cast

Rewrites the tagline, package.json description, and docs/repl.txt opening line to use "Test if ..." / "Tests if ..." phrasing, matching 23 of 26 sibling packages (88.5%). No code, signature, or behavioral changes.

• README.md tagline: "Determine whether ..." → "Test if ..."
• package.json description: "Determine if ..." → "Test if ..."
• docs/repl.txt first line: "Returns a boolean indicating whether ..." → "Tests if ..."

array/base/assert/is-safe-data-type-cast

Rewords documentation to use "Test if ..." / "Tests if ..." phrasing, consistent with 23 of 26 sibling packages (88.5%). No code, signatures, or behavior changed.

• README.md tagline: "Determine whether ..." → "Test if ..."
• package.json description: "Determine if ..." → "Test if ..."
• docs/repl.txt opening line: "Returns a boolean indicating whether ..." → "Tests if ..."

array/base/assert/is-same-kind-data-type-cast

Standardizes documentation phrasing to match the convention used by 23 of 26 sibling packages (88.5%), which prefix descriptions with "Test if" rather than "Determine whether/if". No code, signatures, or behavior changed.

• README.md tagline: "Determine whether ..." → "Test if ..."
• package.json description: "Determine if ..." → "Test if ..."
• docs/repl.txt opening line: "Returns a boolean indicating whether ..." → "Tests if ..."

Validation

• Structural extraction: file tree, package.json key sets, README.md section sequences, manifest.json shape, and test/benchmark/example filenames were collected for all 26 members; no structural outlier survived filtering (the contains package's factory.js is a legitimate semantic difference, and the benchmark.js vs benchmark.length.js split tracks single-value vs array-input function shape).
• Semantic extraction: each package's lib/main.js and lib/index.js was parsed for public signature, return kind, validation prologue, error construction, JSDoc shape, and @stdlib/* source-level dependencies. All 26 members return boolean with no validation prologue (these are base internal helpers, by design).
• Three-pass review of each candidate: a semantic review confirmed that all three cast packages genuinely return booleans and that the rewording carries no meaning loss; a cross-reference review (grep across lib/node_modules/@stdlib/) confirmed that the deviating phrases appear only in the three outliers' own files (no fixture, test, or sibling-package README embeds them); a structural review confirmed that the majority opener applies uniformly across 7 sampled conforming packages and reads naturally on the cast packages.
• Deliberately excluded: opener style in lib/main.js JSDoc, lib/index.js @module block, and docs/types/index.d.ts (no clear majority opener in the namespace); the README ## Notes section sequence split (no clear majority); per-package keywords arrays (intentionally diverge by package subject); is-accessor-array @param {Object} (the function dereferences .get and would crash on null/undefined, so the restrictive type hint is semantically appropriate for a base helper).

Disclosure

If you answered "yes" to using AI assistance, please provide a short disclosure indicating how you used AI assistance. This helps reviewers determine how much scrutiny to apply when reviewing your contribution. Example disclosures: "This PR was written primarily by Claude Code." or "I consulted ChatGPT to understand the codebase, but the proposed changes were fully authored manually by myself.".

This PR was prepared by Claude Code. It surveyed all 26 packages under @stdlib/array/base/assert/, identified the three documentation surfaces with a ≥75% majority opener, and rewrote the three outlier packages' leading phrases to match. Each correction was reviewed by independent semantic, cross-reference, and structural validation passes before any file was modified. No behavior, signatures, or test expectations were changed.
