[Bug]: iOS trash button does not remove a persisted environment

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/mobile

Steps to reproduce

1. Install the current T3 Code iOS app from the App Store.
2. Open Environments; a direct environment saved by an older installation is restored even after reinstalling the app.
3. Expand the stale/offline environment.
4. Tap the red trash button.
5. Force-quit/relaunch the app and restart the iPhone, then repeat.

The stale row in this reproduction is a direct saved environment, not a T3 Connect relay environment.

Expected behavior

Tapping the trash button should present the “Remove from this device?” confirmation and, after confirmation, remove the saved environment and its local credentials/catalog data.

Actual behavior

Tapping the trash button has no visible effect: no confirmation alert appears and the environment is not removed. The behavior persists after force-quitting the app and restarting the iPhone.

The environment also survives deleting and reinstalling the app. This is consistent with the catalog being stored through Expo SecureStore/iOS Keychain (t3code.connection-catalog.v1), whose data can survive reinstall. The current mobile handler appears intended to call Alert.alert("Remove from this device?", ...), but that alert is never presented in this state.

Relevant source paths:

• apps/mobile/src/connection/catalog-store.ts
• apps/mobile/src/persistence/mobile-secure-storage.ts

Impact

Minor bug or occasional failure

Version or commit

Current iOS App Store release installed 2026-09-15 (exact build not shown)

Environment

T3 Code iOS app on iPhone; direct saved environment; stale endpoint offline

Logs or stack traces

Screenshots, recordings, or supporting files

No response

Workaround

None. Force-quit, restart, and reinstall do not clear the entry because the connection catalog persists in iOS Keychain. The stale row can only be ignored.

Start in apps/mobile/src/state/use-remote-environment-registry.ts at onRemoveEnvironmentPress, then trace persistence through apps/mobile/src/connection/catalog-store.ts and apps/mobile/src/persistence/mobile-secure-storage.ts. Reproduce with a stale direct saved environment on iOS and verify that the removal confirmation appears and that the environment, credentials, and catalog data are gone after relaunch.
