Explanation of Change

This PR removes the last layer of full-transaction subscriptions in the MoneyRequestConfirmationListFooter subtree:

  1. ConfirmationFieldList no longer reads the transaction at all. The two hooks it calls (useFooterDerivedFlags, useFooterTagVisibility) now self-subscribe to disjoint narrow slices (5 fields + 1 field).
  2. The footer no longer receives the transaction as a prop. Each of the 4 sections self-resolves its own narrow slice via useTransactionSelector. The footer receives isScanRequest: boolean instead.

Fixed Issues

$ #90385
PROPOSAL:

Tests

Tests

  1. Manual expense: open a chat → +Create expenseManual → enter an amount, pick a participant → Next. Verify all fields render on the confirmation page (Amount, Description, Merchant, Category, Date, Tags, Tax, Attendees, toggles, Report).

  2. Scan flow: +Create expenseScan → take a photo or pick from gallery. Verify the confirmation page enters compact mode (only required fields + receipt thumbnail). Tap Show more → optional fields appear.

  3. Distance flow: +Track distanceManual → add 2 waypoints → Next. Verify the map renders at the bottom of the modal with the route, and Distance + Rate fields display correctly. Try an invalid waypoint → verify the pending/error indicator shows in place of the map.

  4. Per-diem flow (workspace with per-diem rates): +Create expensePer diem → pick destination + dates. Verify Time / Rate / Destination fields render. Submit → expense posts with the correct rate and amount.

  5. Invoice flow: +Send invoice → continue. Verify the Send from row shows your invoicing workspace. Tap it → pick a different workspace → display updates.

  6. Split bill: group chat → +Split expense → enter amount, pick participants → Next. Edit Merchant and Description individually → verify each saves. Submit → split posts with correct per-person amounts.

  7. Edit existing expense: open one → tap Amount, Description, Merchant, Category, Tag, Tax individually → change each → verify each saves.

    • 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 any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
    • 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 shown in the product is localized by adding it to src/languages/* files and using the translation method
      • If any non-english text was added/modified, I used JaimeGPT to get English > Spanish translation. I then posted it in #expensify-open-source and it was approved by an internal Expensify engineer. Link to Slack message:
    • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
    • 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)
    • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.

  • 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

  • I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
  • I verified any variables that can be defined as constants (ie. in CONST.ts or at the top of the file that uses the constant) are defined as such
  • I verified that if a function's arguments changed that all usages have also been updated correctly
  • If any new file was added I verified that:
    • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
  • If a new CSS style is added I verified that:
    • A similar style doesn't already exist
    • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
  • If new assets were added or existing ones were modified, I verified that:
    • 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 code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
  • 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 a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
  • 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.

Shouldn't we subscribe after the iouType check? Might not create much difference since anyways it would return, but still maybe it can be slightly better for perf?

Yeah, that makes sense, applied the change. I believe the perf will be better since flows that don't apply to the section now skip the transaction subscription entirely

Help site review — no changes required

I reviewed the changes in this PR against the help site files under App/docs/articles.

Conclusion: No help site updates are needed.

This is a pure internal performance refactor. It decouples MoneyRequestConfirmationListFooter and its sections from the full transaction prop, replacing it with narrow Onyx slice subscriptions (useTransactionSelector + per-section selectors) and passing isScanRequest: boolean instead of the whole transaction. There are no user-facing changes:

  • No new features, settings, tabs, or buttons
  • No changes to product copy, labels, or flows (Manual / Scan / Distance / Per-diem / Invoice / Split all behave identically)
  • No new or modified UI that an end user would interact with

Since the help site documents product behavior — which is unchanged here — there's nothing to add or update.

Because no documented behavior changed, I did not create a draft help site PR.

@OlimpiaZurek, please confirm this assessment — if you believe any documented behavior is affected, let me know and I'll create the help site PR.

Help site review: No changes required

I reviewed the changes in this PR and no updates to the help site files under App/docs/articles are required.

Why: This is a purely internal performance refactor. It changes how the MoneyRequestConfirmationListFooter subtree subscribes to Onyx transaction data — moving from a single full-transaction subscription to narrow, per-section slices via useTransactionSelector. No user-facing behavior, UI text, labels, flows, or features change as a result.

Evidence
  • All 11 changed files are under src/components/ (component/hook/selector code and one UI test). No src/languages/* strings were added or modified.
  • The footer now receives isScanRequest: boolean instead of the full transaction prop, and each section self-resolves its own data slice — an internal data-subscription change only.
  • The confirmation page renders the same fields (Amount, Description, Merchant, Category, Date, Tags, Tax, Attendees, Report, etc.) across the same flows (manual, scan, distance, per-diem, invoice, split). Nothing in the documented user experience changes.

Since no documentation updates are needed, I did not create a draft help site PR.


@OlimpiaZurek, please review the linked help site PR and confirm it reflects the current behavior. Then mark the linked help site PR Ready for review

(Note: no help site PR was created because this PR contains no user-facing changes that would require documentation updates. If you believe a docs change is warranted, let me know what behavior to document and I'll create the draft PR.)
