Deploy Blocker Analysis

Causing PR: Use useDecisionModal for Search bulk actions and SelectionToolbar alerts (high confidence). It is a real regression: production dismisses the modal on browser Back.

Recommendation: Revert. The revert applies cleanly to staging (a3d62cc) and main (7e9ad84). The PR is a refactor, so reverting costs little. There is no verified small roll-forward fix yet.

Root cause: The PR replaced the inline <DecisionModal> in the Search screen with the global useDecisionModal modal, which renders at the app root. Before, browser Back navigated away and the modal went with the screen. Now the modal lives outside the screen, so only its history back-guard can close it, and that guard does not fire in this flow.

Investigation details

Why this PR

It is the only PR in Deploy Checklist: New Expensify 2026-10-15 that changes the offline alert in Search bulk actions or SelectionToolbar.
Offer export templates when a group row is selected on a grouped search and [Payment due @truph01] fix: Add Contains / Equal to match type for the Merchant filter [80823] also touch useSearchBulkActions.ts, but not the offline modal.
The navigation PRs in this release (Keep split navigator state when navigating to the only sidebar screen on narrow layout #103746, [NoQA] Fix import/no-cycle - part 16 #103180, Restore last visited page on cold start for public domain accounts #103818) do not affect modal back handling.
The modal, popover, BulkActionBar, and useSyncModalWithHistory code is identical between production (5ca624c) and staging (a3d62cc).
The PR merged 2026-10-14 and is in 9.5.10-0. Its test notes say browser Back on web wasn't tested. They also report a stuck SelectionToolbar Export offline alert on Android.

Production

The alert was an inline modal with no back handling: SearchBulkActionsButton.tsx:276-284.

Staging

Offline paths call showOfflineModal(): useSearchBulkActions.ts:686 defines it, and useSearchBulkActions.ts:1247 calls it for Basic export. SelectionToolbar does the same at index.tsx:96, :120, and :183.
That opens the global modal with shouldHandleNavigationBack: true (useDecisionModal.ts:11-14). The modal renders at the app root (App.tsx:130).
On Back, the guard in useSyncModalWithHistory/index.ts:61-125 should call onClose (DecisionModalWrapper.tsx:48). In this flow it doesn't.

Why the guard doesn't fire (unconfirmed hypothesis): In @react-navigation/native 7.4.1, browser Back sends goBack() to the innermost active navigator. If the Search stack or tab history can go back, it handles the action, so the root-level guard entry is never removed. I did not reproduce this in a running app.

Why not a quick fix

Setting shouldHandleNavigationBack: false makes it worse: Back navigates, but the root modal stays on top.
Closing the modal from a navigation listener risks an extra browser back when the guard cleans up.
Before re-landing, prove the guard closes on browser Back in Search and SelectionToolbar, and add a test for it.

Severity: Low. It affects web only, offline only, after browser Back, and "Got it" still dismisses it. Demoting is defensible if the team wants to keep the refactor. Given the clean revert and the Android stuck-alert risk, reverting is the safer choice.

Next Steps: Reply with @MelvinBot <your feedback> to refine this analysis.

I suppose it's a separate issue and not a regression
Since all modals were broken
