Summary

Show hot-topic commit matches newest first by default, remove the redundant mobile focus outline from semantic-search tabs, and replace canned search suggestions with current hot topics.

This is a separate follow-up to #1452, with three commits:

1. Apply latest() to hot-topic results and simplify mobile search-tab focus.
2. Replace suggested searches with hot topics in the search dialog and results page.
3. Prevent hovering hot topics from running searches; preserve prefetch for other results.

Changes

• Reuse the supplied semantic matches, filtering to the past seven days and sorting newest first without another commit search. Hot-topic rendering uses the shared server timestamp to keep server and browser filtering consistent.
• Keep Most relevant as the regular search default. Mobile tabs use their selected underline as the focus indicator; desktop keyboard focus retains its outline.
• Reuse the existing shared hot-topic data and sidebar list in the search page. Topic options in the dialog support pointer and keyboard navigation to the topic page, while recent searches keep their existing behavior.
• Handle missing/empty topic lists and completed guest searches without displaying a perpetual loading message, including throttled searches. Remove the unused canned suggestions and give repeated hot-topic regions unique accessible heading IDs.

Preview

Search page — desktop, light

Search dialog — mobile emulation, dark

Hot topic — newest first, mobile emulation

Regular search — mobile focus underline

Summary by CodeRabbit

• New Features
  • Search dialogs and results pages display current hot topics. Selecting a topic opens its recap with matching commits from the past week, newest first.
  • Signed-in users see their three most recent distinct searches above hot topics; guests see neither hot topics nor retained search history.
  • Empty searches provide clearer guidance, and topic options appear when a search has no results.
• Bug Fixes
  • Recent commit results use the page’s current time, improving consistency in which commits appear.
• Documentation
  • Updated search guidance to describe hot topics, recaps, and recent-search availability.

Walkthrough

Search surfaces now show hot topics instead of predefined suggested queries. Selecting a topic opens its headline page, which displays matching commits from the previous seven days, newest first. Signed-in users also see recent searches.

Changes: Hot-topic search and headline results

Layer / File(s)	Summary
Display and select hot topics resources/js/pages/search/index.tsx, resources/js/components/hot-topics.tsx, resources/js/components/search-dialog.tsx, resources/js/lib/commit-search.ts, tests/Unit/SearchDialogComposition.test.tsx, KNOWLEDGE_BASE.md	The search page and dialog display hot topics instead of predefined suggestions, and the search page renders recent searches. Selecting a dialog topic opens its headline page. Topic links disable prefetching, and the HotTopics heading uses a generated ID. Tests cover topic keyboard interactions and guest search states.
Filter headline-page results resources/js/lib/commit-search-results.ts, resources/js/pages/headline/show.tsx, tests/Unit/CommitSearchResults.test.ts, KNOWLEDGE_BASE.md	The headline page filters matching commits to the previous seven days using the page timestamp, then passes the results to SearchResults. A test checks the supplied timestamp.

Merge Risk: Minimal · up to b4a1c

The changed search and headline behavior has no established merge-blocking risk.

Security architecture risk: Low · up to 2ae68

The new navigation uses existing authenticated routes and viewer-filtered data. No authorization regression was identified. Automatic topic prefetching can add search work before navigation, while its cancellation, caching, and failure-recovery behavior remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated expansion is additional navigation and speculative access to an existing same-origin headline endpoint under the current user's identity. Full requests can invoke embedding, database, and relevance work, but retain the existing per-user rate limit. No new service credentials, privilege grant, or cross-tenant authority was identified in this flow.

Trust Boundaries and Controls

• observed — The server remains the enforcement point: the route requires authentication, the controller supplies the authenticated viewer, and result queries enforce viewer visibility. The dialog adds a consumer of the same topic set already exposed in the aside rather than a new data producer or authorization path.

Resilience and Maintainability Implications

• observed — Existing logout behavior flushes prefetched pages, and local sign-in regenerates the session and forces a full location change. These are relevant identity-transition controls, but do not prove cancellation, failed-prefetch cleanup, or cache invalidation across every authentication transition.

Full details: Title check

Explanation

The title names the two primary changes: showing the latest hot-topic matches and suggesting hot topics in search. The changeset matches both. The search dialog and search page replace canned suggested queries with hot topics, and the hot-topic recap now shows commits from the past seven days, newest first. The title omits the mobile search-tab focus indicator change, which is a minor secondary part of the work and does not need to be in the title.

Full details: Docstring Coverage

Explanation

Docstring coverage is 14.29% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 7 functions across 7 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
