📝 Summary

Summary by CodeRabbit

• New Features
  • Security downgrade alerts now include a “File Changes” link when a trusted version is available, allowing comparison with the downgraded version.
• Tests
  • Added checks for the comparison link with package names, its absence when no trusted version is available, and alert visibility when downgrade details are cleared.
  • Updated accessibility test data to include the package name.

The downgrade alert now shows a “File Changes” link when a trusted version is available. The link uses the package name and trusted and downgraded versions. Tests cover two packages and alert states with and without a trusted version.

Changes: Package downgrade diff link

Layer / File(s)	Summary
Pass package details and render the diff link app/components/Package/Install/Dropdown.vue, app/components/Package/SecurityDowngradeAlert.vue	The install dropdown passes the package name to the alert. When a trusted version exists, the alert renders a link to compare the trusted and downgraded versions.
Validate the link and alert states test/nuxt/components/Package/SecurityDowngradeAlert.spec.ts, test/nuxt/a11y.spec.ts	Tests check the diff link for vue and @nuxt/kit. They also check that the link is absent without a trusted version and that the alert disappears when downgrade is null.

The diff link behaves correctly. An additional test would strengthen regression protection, but this improvement need not block merging.

Explanation

Issue #2345 requests a quick link from the trust downgrade box to show package changes. SecurityDowngradeAlert.vue adds a File Changes link that uses diffRoute(packageName, trustedVersion, downgradedVersion). The link renders only when trustedVersion exists. Dropdown.vue supplies packageName. Component tests verify the diff targets for scoped and unscoped packages and verify the hidden-link case. The accessibility test supplies the new required prop.

Full details: Out of Scope Changes check

Explanation

The changed files support issue #2345. The component change implements the diff link. The Dropdown.vue change supplies its required package name. The component and accessibility tests cover the new behaviour. No unrelated change appears in the reviewed pull-request summary or inspected diffs.

Add a spec case for a false publisher flag with a defined trusted version.

35-35: Trivial · Functional Correctness · Quick win

Add a spec case for a false publisher flag with a defined trusted version.

The diff link depends only on trustedVersion. The component specs do not render that combination. The two component cases use downgradedTrustedPublisher: true with trustedVersion: '1.9.0', and downgradedTrustedPublisher: false with no trustedVersion. A change that gated the link on the publisher flag would still pass both cases. The producer can return the missing combination, so add a case that asserts the link is present.
