📝 Walkthrough

Summary by CodeRabbit

• Refactor
  • Standardised the normalization of licence information across requested versions and package-level sources for consistent display and handling.
  • Centralised the representation of licence values to improve consistency, maintainability and reduce discrepancies in how licences are surfaced across the app.

Walkthrough

Adds a normalizeLicense helper and uses it to normalise per-version and returned license values in package transform logic; consolidates the packument license union into an exported PackumentLicense type alias.

Changes

Package license normalisation

Layer / File(s)	Summary
Data Shape shared/types/npm-registry.ts	Adds exported `PackumentLicense = string
Core Implementation app/composables/npm/usePackage.ts	Adds internal normalizeLicense(license?: PackumentLicense) helper returning a normalized string or undefined.
Transformation / Wiring app/composables/npm/usePackage.ts	transformPackument now computes versionLicense = normalizeLicense(version.license) once per version, assigns it to the requested versionData and each filteredVersions entry, and uses normalizeLicense when selecting the returned top-level license.

🚥 Pre-merge checks | ✅ 4

✅ Passed checks (4 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title accurately reflects the main change: fixing license display to show the correct license from the selected package version rather than the latest version.
Description check	✅ Passed	The description clearly relates to the changeset by demonstrating the bug fix through before/after screenshots showing that glob v9.3.5 now displays the correct ISC license instead of BlueOak.
Linked Issues check	✅ Passed	The code changes successfully address both linked issues: normalising license handling via a helper function and ensuring the correct licence is retrieved from the requested version rather than the latest package data.
Out of Scope Changes check	✅ Passed	All changes are directly related to the stated objectives: the new normaliseLicense helper and PackumentLicense type are introduced solely to support correct licence retrieval from the selected version.

Inline comments:
In `@app/composables/npm/usePackage.ts`:
- Line 119: The current assignment uses normalizeLicense(versionData?.license ||
pkg.license) which incorrectly falls back to pkg.license even when a specific
version is selected; change the logic so that when a specific version is
selected you only use versionData?.license (no top-level fallback), and only
fall back to pkg.license when no version is selected (e.g., check the presence
of the version/selectedVersion variable and call normalizeLicense with
versionData?.license when a version is provided, otherwise use
versionData?.license || pkg.license). Ensure this change touches the line using
normalizeLicense, versionData, and pkg.license so the top-level license is not
shown for selected versions.
