# Phase 2.1 Verification Report — App Shell, Navigation & Search Foundation

**Phase Goal:** Build the app shell, navigation, and search foundation — type-safe nav graphs, glass design tokens, glass surface primitive, dock + search chrome, per-tab search VMs, empty-state tab screens, and final Koin/integration wiring.

**Verdict:** **PASS**

All 5 ROADMAP success criteria verified, all 7 V-anchor automated tests present without `@Ignore`, iOS compile + linkDebugFrameworkIosSimulatorArm64 green, and 8/8 plans executed with summaries.

## ROADMAP Success Criteria

| # | Criterion (paraphrased) | Status | Evidence |
|---|---|---|---|
| 1 | Authenticated user lands in shell, can switch between 4 tabs without signing out | PASS | `App.kt:66-69` routes `RootRoute.Shell -> AppShell()`; `AppShell.kt` hosts `RootNavHost` with 4 nested graphs; `DockBar` calls `navigateToTab(dest.graphRoute)` |
| 2 | Each tab has its own back-stack boundary; intentional empty states | PASS | `RootNavHost.kt` uses 4 `navigation<*Graph>(startDestination = *Home)` blocks; `NavExtensions.navigateToTab` applies `popUpTo(...){saveState=true}; launchSingleTop=true; restoreState=true` (V-01); `Tab*Screen` composables render `EmptyState` with anticipatory Polish copy |
| 3 | Compose Unstyled / renderless primitives, Material 3 only legacy | PASS | New shell composables use `BasicText`/`BasicTextField` from compose-foundation; zero `androidx.compose.material3` imports in shell/dock/search/glass/empty packages (per executor reports); MaterialTheme retained only in `RecipeTheme.kt` for legacy auth screens |
| 4 | Liquid library used for chrome with fallback path | PASS | `GlassSurface.kt` dispatches via `LocalGlassBackend` to `LiquidGlassSurface` / `HazeGlassSurface` / `FlatGlassSurface`; `GlassBackend.kt` has `resolveGlassBackend(settings, isDebugBuild, default)` with debug override (V-02, V-03); registered as `single<GlassBackend>` in `ShellModule.kt` defaulting to Liquid |
| 5 | Search button functional: open/close/clear/query echo, intentional empty body | PASS | `RecipesSearchViewModel` / `PantrySearchViewModel` expose open/close/onQueryChange/clear with locked semantics (close clears query, clear preserves isOpen) — covered by V-05/V-06/V-07 tests; `SearchPill.kt` is a 44dp inline pill with `BasicTextField` + clear/close icons; `FloatingSearchButton` gated to Recipes/Pantry only |

---

## Validation Anchors V-01..V-07

| Anchor | Test File | Status |
|---|---|---|
| V-01 | `commonTest/.../navigation/NavigationTest.kt` | Real assertions (no `@Ignore`) — 3 cases passing |
| V-02 | `commonTest/.../ui/components/glass/GlassBackendTest.kt` | Real assertions — backend default + parsing |
| V-03 | `commonTest/.../ui/components/glass/GlassBackendOverrideTest.kt` | Real assertions — debug override + production short-circuit |
| V-04 | `commonTest/.../ui/screens/shell/AppShellGateTest.kt` | Real assertions — 5 AuthState×hasUser cases via pure `resolveRootRoute` |
| V-05 | `commonTest/.../ui/screens/recipes/RecipesSearchViewModelTest.kt` | Real assertions — 5 cases (open/query/close clears, etc.) |
| V-06 | (same file as V-05) | Real assertions — `clear()` resets only query, isOpen=true |
| V-07 | `commonTest/.../ui/screens/pantry/PantrySearchViewModelTest.kt` | Real assertions — 3 cases parity with Recipes |

`grep -r '@Ignore' composeApp/src/commonTest/` → **0 results** (all Wave-0 stubs replaced with real assertions).

## Build & Test Verification (this verification run)

- `./gradlew :composeApp:iosSimulatorArm64Test --tests "dev.ulfrx.recipe.navigation.*" --tests "dev.ulfrx.recipe.ui.components.glass.*" --tests "dev.ulfrx.recipe.ui.screens.shell.*" --tests "dev.ulfrx.recipe.ui.screens.recipes.RecipesSearchViewModelTest" --tests "dev.ulfrx.recipe.ui.screens.pantry.PantrySearchViewModelTest"` → **BUILD SUCCESSFUL**
- `./gradlew :composeApp:linkDebugFrameworkIosSimulatorArm64` → **BUILD SUCCESSFUL** (iOS sim framework link green)

## Required Artifacts (existence + substantive)

All files referenced in the 8 plan SUMMARYs exist on disk.

### Theme tokens (Plan 02.1-02)
- `ui/theme/RecipeColors.kt` — semantic light/dark palette
- `ui/theme/RecipeTypography.kt` — display/title/body/label scale
- `ui/theme/RecipeSpacing.kt` — xs/sm/lg/xl/xxl/xxxl
- `ui/theme/RecipeShapes.kt` — pill/circle radii
- `ui/theme/RecipeGlass.kt` — border/shadow/blur defaults
- `ui/theme/RecipeTheme.kt` — providers + MaterialTheme wrapper + LocalGlassBackend wiring

### Glass primitive (Plan 02.1-03)
- `ui/components/glass/GlassBackend.kt` — enum, CompositionLocal, resolver
- `ui/components/glass/GlassSurface.kt` — public dispatcher
- `LiquidGlassSurface.kt`, `HazeGlassSurface.kt`, `FlatGlassSurface.kt` — three backends
- `GlassBackdrop.kt` — shared sampling source
- `IsDebugBuild.kt` (common) + `.ios.kt` + `.android.kt` (actuals)

### Navigation (Plan 02.1-04)
- `navigation/Routes.kt` — 8 `@Serializable data object` (4 graph + 4 home)
- `navigation/BottomBarDestination.kt` — enum in D-03 order, `hasSearch` flag
- `navigation/RootNavHost.kt` — single root with 4 nested `navigation<*Graph>` blocks
- `navigation/NavExtensions.kt` — `navigateToTab` four-flag contract

### Shell composables (Plan 02.1-05)
- `ui/screens/shell/ShellViewModel.kt` — (activeTab, searchOpen) StateFlow
- `ui/screens/shell/AppShell.kt` — authenticated root, GlassBackdropSource + bottom chrome column
- `ui/components/dock/DockBar.kt` — collapsible 4-tab dock with animateContentSize + AnimatedContent
- `ui/components/dock/FloatingSearchButton.kt` — 44dp glass button

### Search (Plan 02.1-06)
- `ui/screens/recipes/RecipesSearchViewModel.kt` — open/close/onQueryChange/clear + nullable SearchSource hook
- `ui/screens/pantry/PantrySearchViewModel.kt` — parity
- `ui/components/search/SearchPill.kt` — 44dp inline GlassSurface pill with BasicTextField

### Empty state + tab screens (Plan 02.1-07)
- `ui/components/empty/EmptyState.kt` — reusable composable with mergeDescendants a11y
- `ui/screens/{planner,recipes,pantry,shopping}/{*Screen,*ViewModel}.kt` — 8 files

### Final integration (Plan 02.1-08)
- `di/ShellModule.kt` — Koin: GlassBackend single + ShellViewModel + 4 tab VMs + 2 search VMs
- `di/AppModule.kt` modified: `includes(authModule, userModule, shellModule)`
- `App.kt` modified: `RootRoute` enum + `resolveRootRoute()` + Authenticated → `AppShell()`
- `RootNavHost.kt` modified: `TabHomePlaceholder` calls replaced with real `Tab*Screen` via `koinViewModel(viewModelStoreOwner = parent)`

---

## Resource Strings (i18n hygiene)

`composeResources/values/strings.xml` carries 24 keys total: 7 auth (pre-existing) + 4 shell tabs + 2 search placeholders + 3 search a11y + 8 empty-state. Zero hardcoded Polish literals in new `.kt` files (all flow through `stringResource(Res.string.*)`) — satisfies UI-01 and convention #9.

---

## Key Wiring Verification

| Link | Status | Evidence |
|---|---|---|
| `App.kt` → `AppShell` (auth gate) | WIRED | `App.kt:13` import + `App.kt:69` `RootRoute.Shell -> AppShell()` |
| `AppModule.kt` → `shellModule` | WIRED | `AppModule.kt:11` `includes(authModule, userModule, shellModule)` |
| `RootNavHost` → 4 Tab Screens | WIRED | `koinViewModel<*ViewModel>(viewModelStoreOwner = parent)` per tab; no `TabHomePlaceholder` left |
| `RecipeTheme` → `LocalGlassBackend` | WIRED | `RecipeTheme.kt` includes `LocalGlassBackend provides koinInject<GlassBackend>()` |
| `DockBar` tab cell → `navigateToTab` | WIRED | `AppShell` dispatches `navigateToTab(dest.graphRoute)` on tab change |
| `AppShell` → `SearchPill` + per-tab Search VM | WIRED | When-branches for both Recipes and Pantry; gated by `activeTab.hasSearch` |

---

## Anti-Patterns Scan

- Zero `androidx.compose.material3` imports in new shell/dock/search/glass/empty packages (executor reports + spot-checks).
- Zero direct `liquid` / `haze` imports outside the dedicated backend files.
- No `safeContentPadding()` in AppShell (Pitfall F honored).
- No hardcoded Polish literals in commonMain `.kt` files.
- No `TODO(02.1-08)` markers remain after Plan 08.

## Out-of-Scope / Acknowledged Items

1. **Pre-existing Spotless violations in 38 unrelated files** (LokksmithOidcSupport, OidcClient, AuthSession, etc.) — confirmed by Plan 08 executor via `git stash` + `spotlessCheck` to predate this phase. **OUT OF SCOPE for Phase 2.1**; flagged for a future cleanup pass. Does not affect Phase 2.1 verdict.
2. **Manual iOS-simulator smoke tests V-08..V-11** (visual chrome, animation feel, search affordance UX, Liquid look-and-feel) — deferred to user smoke-test pass per VALIDATION.md (no simulator in autonomous run). Static checks confirm code paths are wired correctly; visual confirmation belongs to the user's manual runbook execution.
3. **`./gradlew :composeApp:check`** is RED only because of the 38-file pre-existing Spotless debt. The Phase 2.1 owned files all pass Spotless (Plan 08 commit `a6f0d46`).

---

## Regression Check

- Phase 2 auth flow preserved: `LoginScreen` / `SplashScreen` / `MaterialTheme` wrapper untouched in core paths.
- `PostLoginPlaceholderScreen.kt` and `PostLoginViewModel.kt` source files preserved on disk per CONTEXT line 101 (logout-bridge possibility), only their imports/call site removed from `App.kt`.
- No deletions to `auth/` or `user/` packages; the brief Plan 01 unrelated-staged-file accident was repaired in commit `1066e9b` before any other work.

---

## Gaps

**None.** All 5 ROADMAP success criteria, all V-01..V-07 anchors, and all 8 plans are complete and substantive. Phase 2.1 is ready to mark done.
