 - Current Discourse / FTTransfer findings point to the `BankInformationView` path rather than XFlow directly: XFlow appears to finish before `BankInformationView` takes over, and the web-view reload looks like a SwiftUI recomposition/state issue in the playground path
 - Continue the Discourse / FTTransfer investigation to verify root cause and any remaining relationship to XFlowViewMaker before assigning ownership or creating a story
 - Jeff asked David to try to resolve the Discourse consumer issue by end of day on April 30 if possible
+- Deeper Discourse / FTTransfer analysis now points to presentation-layer SwiftUI identity/lifecycle churn around `BankInformationView` and `BankSetupWebView`: XFlow eventing appears to set shared consumer-observed state, but current evidence does not show it directly mutating view identity, host lifecycle, or alert state.
+- The working non-XFlow route appears to avoid the issue because it bypasses the extra XFlow destination presentation layer and associated state-coupling surface, while the failing playground path keeps the alert/popup transition and cover lifecycle coupled in the same reactive chain.
+- The next implementation direction for the Discourse / FTTransfer issue is a pure SwiftUI fix that decouples alert state from the cover identity chain, avoiding unnecessary UIKit dependencies
 - Before closing out the AO thread, send one more working-group Teams reply that summarizes the original iOS issue, links the Jira comment, Discourse comment, and PR, and separates the remaining `HybridBrokerageAccountOpening` / `JointIdentityCheck` service-side issue
 - The `HybridBrokerageAccountOpening` / `JointIdentityCheck` rule-content issue appears unchanged between QA and Production in Cogstore and should be treated as the remaining service-side follow-up

 # 2026-04-30
 
-## Context Updates
-- Jeff requested confirmation on whether the webview reload issue is tied to `XFlow`. If not, we need to compare the failing flow against Zachary's working non-XFlow entry point to understand the discrepancy.
-- David reported that the issue seems isolated to a premature deallocation in the SwiftUI lifecycle between `BankInformationView` and `BankSetupWebView`, meaning it does not appear to be an `XFlowViewMaker` bug.
+## Focus
+
+- Continue the Discourse / FTTransfer AccountLink investigation and verify whether the web-view reload issue is caused by XFlow/XFlowViewMaker or by the consumer SwiftUI hierarchy.
+
+---
+
+## Work Done
+
+- Compared the failing `FTTransferPlayground` path with the working non-XFlow entry point Zachary referenced.
+- Explored whether XFlow event handling could be contributing to the issue, since similar event/lifecycle concerns came up in prior work.
+- Ran a deeper architecture analysis of the web-view reload behavior with concrete code references.
+- Identified the likely root cause as a SwiftUI view-identity / environment-republish issue around `BankInformationView` and `BankSetupWebView`, not XFlow rendering or XFlowViewMaker lifecycle logic directly.
+
+---
+
+## Findings
+
+- XFlow is definitely the upstream trigger path, but the failure is driven entirely by how the consumer SwiftUI hierarchy anchors the web-view presentation.
+- **Final Root Cause (Modifier-Site Teardown):** The `.ftFullScreenCover` modifier was incorrectly attached to a **volatile branch** of `BankInformationView` (e.g., inside a dynamic loaded/error state view). When the webview triggered an exit alert, the resulting state mutation caused SwiftUI to re-evaluate that volatile branch. This dismantled the presentation anchor and rebuilt it off-screen (`inWindow=false`), resulting in a blank screen.
+- The working non-XFlow route survives because it uses a completely different, stronger modal/coordinator boundary (`BankSetupContainerView`), avoiding this fragile modifier placement.
+- **Verified Solution:** The issue was resolved by moving the `.ftFullScreenCover` and its `shouldShowWebView` observer to the **stable root** of `BankInformationView`. By anchoring the presentation to the static root instead of a dynamic child branch, transient state changes no longer dismantle the presenter. This fixes the bug perfectly using pure SwiftUI, without any UIKit (`UIHostingController`) hacks.
+
+---
+
+## Communication
+
+- David asked Zachary for the working non-XFlow entry point so the failing and working paths could be compared directly.
+- David can now confidently update Jeff and Zachary that XFlow is completely cleared, and the bug was a classic SwiftUI presentation-anchor issue in the playground's consumer code.
+
+---
+
+## Next Steps
+
+- Finalize the PR with the structural fix (moving the cover to the stable root of `BankInformationView`).
+- Share the exact lines changed with Zachary so his team can apply this SwiftUI best practice to other covers in their playground.
+
+---
+
+## Blockers
+
+- None currently.
