 Navigation uses a stack model (like iOS): each forward action pushes the current
 screen onto `state.viewStack`, and "Back" pops it (`pushCurrentView()` and
-`goBack()` in `src/popup/views/helpers.js`). The root screen is either Welcome
-(no wallets) or Home (has wallets). Each screen below gives its view id in
-parentheses; the registry of view ids is the `VIEWS` array in
-`src/popup/views/helpers.js`, and the markup for a screen is the element with id

 # Completed Steps
 
+- 2026-10-07: Back from Settings no longer shows Settings again after the
+  settings gear was pressed on the recovery phrase or a delete wallet screen
+  opened from Settings, with or without a reopen in between
+  ([#481](https://git.eeqj.de/sneak/AutistMask/issues/481)). Those screens take
+  themselves off the Back stack when left, which leaves Settings under Settings;
+  `goBack()` now skips an entry for the screen already showing.
+  `tests/showPhrase.test.js`, `tests/deleteWalletLostPassword.test.js` and
+  `tests/backNavigation.test.js` drive each path.

 - 2026-10-07: `script/discard-dist-on-failure` returns the failed step's own
   exit status even when it cannot write its message, to a closed stderr or to a
   pipe nobody reads any more
