Explanation of Change

Part 5 of a 7-PR series to decompose ReportScreen (#84895).

This PR makes ReportActionsView, ReportActionCompose, and ReportFooter self-subscribing — each component now derives its own data via useOnyx and custom hooks rather than receiving a large prop surface drilled from ReportScreen.

ReportActionsView: reduced from 13 props to 2 (reportID, onLayout). The component now self-subscribes via useOnyx, usePaginatedReportActions, useParentReportAction, and related hooks.

ReportActionCompose: reduced from 11 props to 1 (reportID). Comment submission and task creation logic (previously in the old ReportFooter) were moved into this component. It self-subscribes to the report, transactions, and last report action.

ReportFooter: the old 246-line report/ReportFooter.tsx is deleted and replaced with a thin 118-line inbox/ReportFooter.tsx orchestrator that needs only reportID.

ReportScreen: ~50 lines of prop drilling and unused intermediate computations removed.

Net change: +487/-531 across 10 files (net -44 lines).

Dependencies: PR #85535 (AgentZero context)

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 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.
    • I verified the JSDocs style guidelines (in STYLE.md) were followed
  • 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 tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
  • 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.

Replace three scattered modules (useAgentZeroStatusIndicator hook,
ConciergeReasoningStore, and Pusher reasoning subscriptions in
Report/index.ts) with a single AgentZeroStatusContext that uses a
two-level gate pattern:

- Outer gate (AgentZeroStatusProvider): cheap scalar check — if not
  Concierge chat, renders children with no hooks/Pusher/state overhead
- Inner gate (AgentZeroStatusGate): owns all logic for Concierge chats:
  Onyx subscription, Pusher subscription with per-callback cleanup,
  reasoning state with deduplication, debounced label updates

Consumers (ConciergeThinkingMessage, ReportActionCompose) now read from
context instead of receiving props drilled through 4 levels. The prop
chain ReportScreen → ReportActionsView → ReportActionsList →
ConciergeThinkingMessage is eliminated.

The new eslint-config-expensify@2.0.107 enforces context-provider-split-values:
contexts must not mix data and functions in a single provider.

Split AgentZeroStatusContext into:
- AgentZeroStatusStateContext: {isProcessing, reasoningHistory, statusLabel}
- AgentZeroStatusActionsContext: {kickoffWaitingIndicator}

Export useAgentZeroStatus() for state and useAgentZeroStatusActions()
for actions. Update ReportActionCompose to use the actions hook.
Update tests to use the appropriate hook per test case — state-only
tests use useAgentZeroStatus(), tests needing both spread inline.

…me state

Self-derive shouldSuppressIndicators inside AgentZeroStatusGate using
side-panel context and report actions, then expose it via useAgentZeroStatus().
ConciergeThinkingMessage and a new AgentZeroAwareTypingIndicator wrapper
consume the flag to hide indicators until the user sends a message.

Document the public interface (AgentZeroStatusState, AgentZeroStatusActions)
with JSDoc comments explaining each field's purpose, and add inline comments
to internal state variables, refs, effects, and derived values in the gate.

…hook

Extract useShouldSuppressConciergeIndicators hook that each consumer calls
directly, removing shouldSuppressIndicators from AgentZeroStatusState.
This keeps the context pure (isProcessing, reasoningHistory, statusLabel)
and scopes suppression to Concierge DMs only, fixing the #admins bug.

Avoids defaulting to empty string which violates the no-default-id-values
lint rule.

Replace the 13-prop interface with just reportID + onLayout. The component
now self-subscribes to report data (report, reportActions, reportMetadata,
parentReportAction, transactionThreadReportID, isConciergeSidePanel, etc.)
via hooks. Update all call sites (ReportScreen, MoneyRequestReportView) to
pass only reportID. Widen useConciergeSidePanelReportActions to accept
OnyxEntry<Report> to handle the pre-load undefined window.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
ReportActionCompose now owns the full submit flow (task detection,
addComment, attachment dispatch) and manages the didHideComposerInput
latch internally. The onSubmit prop is removed; ReportFooter is
simplified to pure layout/gating logic.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Internalize all data subscriptions into ReportActionCompose so it only
requires a single `reportID` prop. Computed internally: report (Onyx),
isComposerFullSize (Onyx), lastReportAction (paginated actions +
combined thread actions), reportTransactions (collection hook),
transactionThreadReportID (derived), and pendingAction (ReportUtils).

Remove dead onComposerFocus/onComposerBlur props that were never passed
by any caller. Update all call sites (ReportFooter, ReportScreen,
MoneyRequestReportView) and test fixtures to the new minimal API.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
ReportFooter now accepts reportID instead of report, self-subscribes
via useOnyx, and returns null when the report is not yet loaded. Moved
from report/ReportFooter.tsx to inbox/ReportFooter.tsx to sit alongside
the other self-subscribing screen components.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…ompose

- ReportActionsViewTest: add mocks for usePaginatedReportActions,
  useParentReportAction, useIsInSidePanel, useSidePanelState, and
  useReportTransactionsCollection; simplify render helper to accept
  only reportID; control Concierge side panel state through hook mocks
  rather than props; fix mockUseOnyx to return mockReport so the
  component doesn't early-return the skeleton on missing report

- ReportActionComposeTest: add mocks for usePaginatedReportActions,
  useParentReportAction, useReportTransactionsCollection,
  useShortMentionsList, and useSidePanelState; add beforeEach to
  pre-populate Onyx with the fake report so the component renders
  past its early-return guard
