What changed

  • adds a dedicated Preview Downloads page with the latest accepted build and previous preview history
  • reads public GitHub prerelease metadata while keeping the manifest as the acceptance boundary
  • remembers the last selected version only in the tester's browser and highlights a newer accepted preview
  • adds shared Overview, Downloads, Install, and Testing navigation
  • updates installation and maintainer guidance

Why

Friends testing RecordCove need to see when a new preview is available without being told manually, identify the exact version they selected, and return to older builds when comparing behavior.

Safety boundary

A release is displayed only when its tag and exact GitHub asset identity are valid and it is not newer than the accepted manifest. The newest displayed asset must match the manifest URL, size, and SHA-256 digest exactly. No private RecordCove source or tester download history is exposed.

Verification

  • npm test (11/11 passing)
  • npm run build
  • node --check site/downloads.mjs
  • git diff --check
  • real-browser verification against the public GitHub release API, including previews 4 through 8 and zero horizontal overflow

Warning

Review limit reached

@promisepreston, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 55 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change adds a macOS preview downloads page. It validates releases against an accepted manifest, tracks the selected version in browser storage, updates site navigation, and revises installation guidance.

Changes

Preview downloads

Layer / File(s) Summary
Release validation and selection state
site/downloads.mjs
The release catalog validates manifest-approved GitHub releases, sorts accepted tags, classifies download status, and handles loading errors.
Download page rendering and tracking
site/downloads.html, site/downloads.mjs, site/styles.css, test/site.test.mjs
The page renders latest and historical releases, checksums, metadata, status messages, and remembered-release badges. Tests cover filtering, ordering, links, and download state.
Site navigation and installation guidance
site/index.html, site/install.html, site/testing.html, site/styles.css, INSTALL.md, README.md, test/site.test.mjs
Site navigation and download links now use the Preview downloads page. Documentation describes accepted previews, verification, staged releases, and local version tracking.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🟡 Moderate · up to 7238b

The new preview history can fail to display downloads when the accepted release falls beyond the first 100 GitHub releases, and the added CSS currently fails the supplied style check; merge should wait for pagination and cleanup.

- Line 1: Update the release-fetching flow around RELEASE_API, acceptedReleases,
and loadDownloads to paginate GitHub releases until the manifest.releaseTag is
found, while retaining all eligible releases accumulated across pages. Preserve
the existing selection behavior and error state when the manifest release is
unavailable, and add a regression test covering a manifest release returned on a
later page.

In `@site/styles.css`:
- Line 34: Remove the deprecated word-break: break-word declaration from
.checksum code and .release-checksum code in site/styles.css at lines 34-34 and
56-56; retain overflow-wrap: anywhere in both rules.
