Explanation of Change

SearchPageHeaderCommon called useSearchTypeMenuSections() only to find the current suggested search's label for the title. That hook runs useHasReportAwaitingApproval, which rescans all reports and rebuilds a transactions-by-report index on every report/transaction write. Opening a report from the Spend tab triggers several such writes, so the header spent ~200ms per open redoing a scan that can't change its title.

The header now reads suggestedSearches[currentSearchKey] from useSearchQueryContext(), which is already computed there.

Note: the old lookup only matched items visible in the menu; the new one matches any suggested search, consistent with how Search/index.tsx already titles charts. The difference only shows in rare edge cases (e.g. Approve hidden mid-session after approving the last report as a non-workflow approver), where the new title is more accurate.

Fixed Issues

$ #103155
PROPOSAL:

Tests

  1. Go to the Spend tab
  2. Click each suggested search in the left menu (Expenses, Reports, Submit, Approve, Pay, Export, etc. as available) and verify the header title matches the selected item.
  3. Open a saved search and verify the header shows its name
  • Verify that no errors appear in the JS console

Offline tests

Same as tests while offline.

QA Steps

Same as tests

  • Verify that no errors appear in the JS console

PR Author Checklist

  • I linked the correct issue in the ### Fixed Issues section above
  • I wrote clear testing steps that cover the changes made in this PR
    • I added steps for local testing in the Tests section
    • I added steps for the expected offline behavior in the Offline steps section
    • I added steps for Staging and/or Production testing in the QA steps section
    • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
    • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
    • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
  • I included screenshots or videos for tests on all platforms
  • I ran the tests on all platforms & verified they passed on:
    • Android: Native
    • Android: mWeb Chrome
    • iOS: Native
    • iOS: mWeb Safari
    • MacOS: Chrome / Safari
  • I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
  • I followed proper code patterns (see Reviewing the code)
    • I verified that comments were added to code that is not self explanatory
    • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
    • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
  • If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
  • I followed the guidelines as stated in the Review Guidelines

    • The assets are optimized and compressed (for SVG files, run npm run compress-svg)
    • The assets load correctly across all supported platforms.

  • If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
  • If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
  • If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
  • If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
    • I verified that all the inputs inside a form are aligned with each other.
    • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
  • If the PR adds or modifies the UI:
    • I asked an AI agent to review the changes for accessibility issues and addressed its findings.
    • I tested with a screen reader (VoiceOver on macOS) and verified all new/changed elements are reachable with a logical focus order.
    • I verified all new/changed elements have meaningful accessible names and roles.
    • I verified state changes are announced (e.g. checked/unchecked, expanded/collapsed, selected).
  • I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.
  • If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

Review: looks good to merge. I found no blocking issues.

The new lookup gives the same title as before for every item shown in the menu. The perf win is real because the header no longer mounts useSearchTypeMenuSections.

What I checked
  • Same label source. createTypeMenuSections builds menu items by spreading suggestedSearches[key] and only overrides emptyState, never translationPath (SearchUIUtils.ts:4741). So translate(selectedItem.translationPath) in getSearchPageHeaderTitle.ts:37-39 returns the same string.
  • Saved searches. When currentSearchKey is a saved-search key, suggestedSearches[currentSearchKey] is undefined. That is harmless because activeSavedSearch takes priority in the title helper.
  • Behavior change (hidden items). useSearchKeyParam resolves the key against all of suggestedSearches, not just visible items (useSearchKeyParam.ts:60-66). If a user opens a query that matches a hidden suggested search (for example, an Approve query typed by someone with no Approve item), the header now shows "Approve" instead of "Spend". This matches how the chart title already works (Search/index.tsx:1413), and the PR description calls it out. I think it's an improvement.
  • CI. All checks pass except Check independent approval, which is expected before review approval.

Optional: You could add a small unit test for getSearchPageHeaderTitle with a hidden suggested-search key to lock in the new behavior. It isn't required.

No help site update is needed: this PR is a performance refactor that keeps the same Spend page header titles, so no sentence in docs/articles became incorrect.
