- Replace magic numbers in StoryScreen with design token constants
  (HEADER_HEIGHT=spacing.xxxxxl, ICON_SIZE=spacing.lg, PROGRESS_BAR_HEIGHT=spacing.xxs)
- Extract formatRelativeTime to shared/utils to eliminate duplication
  between hn.mappers and useFeedQuery
- Rename ActivityType → AccentVariant; align values with theme color keys
  ('primary'/'info'/'warning' replacing 'task'/'message'/'alert')
- Add useMemo/useCallback throughout StoryScreen and useFeedQuery
- Add attachLogging(hnClient) for dev HTTP visibility
- Remove dead code: TAB_COMPONENTS route, UIKitScreen, redundant subtitle??undefined
- Add 14 unit tests for parseDomain and mapHnHitToFeedItem
- All 41 tests pass, zero TypeScript errors

Replace JSX-based dynamic config with static config objects:
- Inline all thin stack wrappers (auth, onboarding, settings, home-tabs)
  into a single root-navigator.tsx using createNativeStackNavigator({screens})
- Replace NavigationContainer + AppLayout with createStaticNavigation(RootStack)
- Add useT() to AnimatedTabBar for label derivation — no more tabBarLabel
  prop needed in tab screen options
- Remove dead routes: HOME_STACK, HOME_TABS, SETTINGS_ROOT/LANGUAGE/THEME
- Delete 6 files: auth-stack, onboarding-stack, settings-stack, home-stack,
  home-tabs, AppLayout
- Delete 3 dead feature param-list directories (types now inferred by RN)

Zero type errors, 41 tests pass.

Auto-fix 17 files: import organization, trailing commas, line wrapping.
Zero lint errors, zero type errors, 41 tests pass.

- Extract useShimmer() → src/shared/hooks/useShimmer.ts
  Pure Animated.Value pulse hook, no feature coupling
- Extract SectionHeader → src/shared/components/ui/SectionHeader.tsx
  Label row + optional offline/synced status pill; reusable by any list screen
- HomeScreen imports both from shared; removes ~70 lines of inline code

showPassword, emailFocused, passFocused all replaced by useToggle()
from shared/hooks. Toggle handler is now a stable ref (toggleShowPassword)
instead of an inline arrow.

- Remove duplicate zLoginRequest validation in useLoginMutation
  (AuthService.login already validates; hook was parsing twice)
- Remove hardcoded mutationKey ['auth','login'] — optional and not in authKeys
- Flatten nested offline guard: if (!mock) { if (offline) } → if (!mock && offline)
- Move SessionSchema out of useAuthSessionQuery into auth.schemas.ts
  where all Zod schemas belong (zSessionResponse / SessionResponse)
- Remove .catch(() => undefined) on qc.cancelQueries() in useLogout

- Move useAppLaunch → src/session/ (imports from session layer)
- Move useShimmer → src/features/home/hooks/ (only used in HomeScreen)
- Delete useBackHandler from shared (zero consumers; superseded by
  navigation/helpers/use-back-handler)
- Remove SESSION_RELATED_QUERY_TAGS from shared/constants (cross-feature
  coupling); replace with feature-local tag arrays in useLoginMutation
  and useUpdateProfile, each scoped to their own tag map

- Replace TouchableOpacity with Pressable throughout (ScreenHeader,
  AuthScreen) per react-native-skills guidelines; use style callback
  for pressed opacity feedback instead of activeOpacity
- Remove activeOpacity={1} on social buttons — Reanimated handles
  press animation; Pressable has no built-in feedback
- Extract static inline styles in HomeScreen to StyleSheet.create():
  StoryCard meta row (rendered in FlashList on every item) and
  ListFooter height (constant value)

Memoization:
- ThemePickerModal/LanguagePickerModal: extract ThemeOptionRow/
  LanguageOptionRow as memo'd components — onPress is now a stable
  useCallback([opt.mode/code, onSelect]) instead of a new closure
  created per render per map item
- ThemeScreen: extract ModeButton memo component for same reason
- LanguageScreen: replace 3 inline arrow functions with named
  useCallback handlers (handleEnglish/Russian/German)
- StoryScreen: extract handleClose useCallback for the dismiss button

Accessibility:
- ThemePickerModal/LanguagePickerModal items: add accessibilityRole,
  accessibilityLabel (translated option name), accessibilityState
- SettingsRow: add accessibilityRole (button when pressable, none
  otherwise) and accessibilityLabel derived from label prop

HalfSheet is a generic animated bottom-sheet UI primitive with no
navigation knowledge — it imports only from shared/theme. Living in
navigation/modals/ forced feature screens to import from navigation/
just to render a container component.

- Move navigation/modals/half-sheet.tsx → shared/components/ui/HalfSheet.tsx
- Update ThemePickerModal and LanguagePickerModal imports
- Remove dead `export * from './modals/half-sheet'` in navigation/index.ts
  (default exports are not captured by export *, so it was a no-op)

Same issue as HalfSheet: GlobalModal imports only from shared/theme
and shared/components/ui — no navigation dependency. Feature screens
that use it would have to import from navigation/ for a pure UI shell.

- Move navigation/modals/global-modal.tsx → shared/components/ui/GlobalModal.tsx
- Remove export from navigation/index.ts (no consumers, dead export)

AnimatedTabBar stays in navigation/ — it depends on BottomTabBarProps,
navigation.emit(), and ROUTES, making it genuine navigation infrastructure.

…ptions

Naming:
- BootstrapRoute → InitialRoute
- getBootstrapRoute() → getInitialRoute()
- useBootstrapRoute() → useInitialRoute() (file renamed accordingly)
- All call sites updated: root-navigator, navigation-persistence, useAppLaunch

Result: initialRouteName: getInitialRoute() reads as intended at the
call site; no more indirection through a "bootstrap" name for what is
simply the navigator's starting screen.

Dead code:
- Delete src/navigation/options/ entirely — useNav(), navigation.presets.ts,
  navigation.tokens.ts, tabOptions.tsx were all helpers for the old
  dynamic navigator config, superseded by the static config migration.
  Zero external consumers remained.

- Replace stale dynamic-config references (NavigationContainer, per-feature
  param-list files, useBootstrapRoute) with current static config API
- Add v7-specific rules: screens object, groups vs nesting, if property
  for conditional auth rendering, .with() for dynamic options
- Add params rules: JSON-serializable, IDs only, reserved key list,
  setParams vs replaceParams, popTo for back-passing data
- Add navigation action guide: navigate vs push vs popTo vs popToTop
- Add screen lifecycle rules: useFocusEffect pattern, useIsFocused,
  addListener cleanup
- Add TypeScript rules: type not interface, no useNavigation<T>(),
  CompositeScreenProps, NavigatorScreenParams
- Update half-sheet entry to reference HalfSheet shared component
- Add InteractionManager rule for post-navigation heavy work
- Add empty-directory rule for navigation folder

Navigation:
- Revert root-navigator to dynamic JSX config (Stack.Navigator/Screen)
  with typed generic params; useInitialRoute() hook in component body
- Add HomeTabParamList to root-param-list.ts; export from index.ts
- Update NavigationRoot.tsx and AnimatedTabBar.tsx accordingly

Theme:
- Remove unused italic font variant from fonts.ts
- Add brand.ts token file; export from theme index
- Sync dark/light theme with new token

Auth / User:
- Export AUTH_SESSION_TAGS from auth/api/keys.ts (satisfies AuthTag[])
- Export USER_UPDATE_TAGS from user/api/keys.ts
- Remove dead oauth-brand-colors.ts constant file
- Update useLoginMutation and useUpdateProfile to import named tag arrays

Docs / rules:
- Update navigation.md to reflect dynamic config (not static)
- Minor fixes in CLAUDE.md, react-query.md, shared-services.md, development.md
- Remove rn-architect agent (superseded by rn-code-reviewer)
