Reorganise bottom sheet, recipe detail and meal plan editor

PlanCustomization / IngredientCustomization / AddedIngredient disappear;
PlanEntry now carries List<PlanIngredient> directly. Substitutions,
exclusions, amount overrides, product picks, and added ingredients are
all just whatever ends up in the list. Recipe edits no longer mutate
historic plan entries — load-bearing once consumption tracking lands.

 ## What This Is
 
-A mobile-first meal planning app for a small household — pick recipes for the week, fill a calendar across five meal slots per day, and watch pantry gaps + shopping lists emerge from the plan. Kotlin Multiplatform targeting iOS primarily, with Android, Desktop, and Wasm as secondary targets. Built for me + my partner (shared household plan) with a handful of family/friends as authorized users on the same self-hosted backend.

 ## Context
 
-**Codebase state.** The `~/dev/repo/recipe` directory is a freshly-generated Kotlin Multiplatform Compose template from IntelliJ with four modules: `composeApp` (Android + Desktop + iOS shared UI), `iosApp` (iOS bootstrap), `server` (Ktor, not yet written), and `shared` (common code). No app logic exists yet — this is effectively greenfield with the build infra in place.
+**Codebase state.** The `~/dev/repo/recipe` directory has four modules: `composeApp` (Android + iOS shared UI), `iosApp` (iOS bootstrap), `server` (Ktor), and `shared` (common domain/DTO code). `shared` still has a JVM target because the server consumes it; `composeApp` does not ship Desktop or Wasm targets in v1.
 
 **Reference implementation.** The user built a working PWA at `~/dev/repo/recipe-mockup/` (vanilla JS + Tailwind CDN + nginx/Docker). It implements the same four views (Recipe List, Meal Planner, Pantry, Shopping List) and has mature logic worth mining as a *functional* spec — particularly planner entry customization (substitutions, amount overrides, product selection), shortfall computation over a horizon, and shopping-list aggregation with "bought" session tracking. The mockup's UI design is **not** being carried forward; the user is redesigning visuals around a Liquid-Glass-inspired language.

+**Goal:** Replace the post-login placeholder with the real app shell before household/domain data lands: four persistent top-level destinations (Przepisy, Planer, Spiżarnia, Zakupy), deliberate empty states for each, a working search affordance, and the first shared component layer based on Composables + Liquid instead of growing further around Material 3.
+**Depends on:** Phase 2
+**Requirements:** UI-03, UI-04, UI-09, UI-10
+**Success Criteria** (what must be TRUE):
+  1. After sign-in I land in the main app shell, not the Phase 2 welcome placeholder; I can switch between Przepisy, Planer, Spiżarnia, and Zakupy from the main menu without signing out.
+  2. Each tab has its own navigation state boundary from day 1, so future detail screens can preserve back stacks independently; the initial screens are intentionally empty states, not throwaway placeholders.
+  3. The shared UI foundation uses Composables' Compose Unstyled/renderless primitives for new controls where applicable, with local Recipe components providing the visual styling; Material 3 remains only as temporary legacy auth scaffold until migrated.
+  4. Menu chrome and primary icon buttons use the Liquid library (`io.github.fletchmckee.liquid:liquid`) for the first Liquid-Glass-inspired treatment, constrained to chrome/buttons and backed by a simple fallback path if performance or platform support is not acceptable.
+  5. The search button is functional: tapping it opens a search surface, query input updates state, close/clear actions work, and empty/no-data content is intentional until the recipe catalog read path wires real results in Phase 5.

+<objective>
+Wave 0 — verify the three load-bearing assumptions (A1: Liquid iOS klibs resolve; A2: Material Icons Outlined available; A3: nav-compose 2.9.2 K/N back-stack save/restore), add the four new dependencies to the version catalog and `composeApp` build, and land the six commonTest stub files referenced by VALIDATION.md so V-01..V-07 anchors have target locations from day 1.
+
+Purpose: De-risk the rest of the phase. If A1 fails, the GlassSurface backend default flips to Haze before any UI code is written; if A2 fails, `material-icons-extended` is added before screens reference icons.
+Output: Updated `libs.versions.toml`, updated `composeApp/build.gradle.kts`, six failing-but-compiling test stubs.

+    Edit `gradle/libs.versions.toml`:
+
+    1. Append to `[versions]` block (after the existing `multiplatformSettings = "1.3.0"` line, preserving alphabetical/grouping conventions seen in the file):
+       ```toml
+       navigation-compose = "2.9.2"
+       compose-unstyled = "1.49.9"
+       liquid = "1.1.1"
+       haze = "1.6.10"
+       ```
+    2. Append to `[libraries]` block (after the existing Phase 2 client block, separated by a comment header `# Phase 2.1 — App shell foundation (UI-03, UI-04, UI-09, UI-10)`):
+       ```toml
+       navigation-compose = { module = "org.jetbrains.androidx.navigation:navigation-compose", version.ref = "navigation-compose" }
+       compose-unstyled = { module = "com.composables:composeunstyled", version.ref = "compose-unstyled" }
+       liquid = { module = "io.github.fletchmckee.liquid:liquid", version.ref = "liquid" }
+       haze = { module = "dev.chrisbanes.haze:haze", version.ref = "haze" }
+       ```
+
+    Edit `composeApp/build.gradle.kts`:
+
+    3. Inside the `commonMain.dependencies { ... }` block (locate by grep), append (after existing `implementation(libs.multiplatform.settings)` line, or after the last existing `implementation(...)` in commonMain):
+       ```kotlin
+       implementation(libs.navigation.compose)
+       implementation(libs.compose.unstyled)
+       implementation(libs.liquid)
+       implementation(libs.haze)
+       ```
+
+    4. Verify A2 — Material Icons Outlined availability. Run a quick Gradle resolution probe:
+       ```bash
+       ./gradlew :composeApp:dependencies --configuration commonMainImplementation 2>&1 | grep -E "(material-icons-extended|material3)" | head -20
+       ```
+       The four icons referenced in UI-SPEC (`Icons.Outlined.CalendarMonth`, `MenuBook`, `Inventory2`, `ShoppingCart`) are NOT in the baseline icon set. They live in `material-icons-extended`. Add to catalog (per RESEARCH § Pitfall D):
+       ```toml
+       # in [versions]:
+       compose-material-icons-extended = "1.7.3"
+       # in [libraries]:
+       compose-material-icons-extended = { module = "org.jetbrains.compose.material:material-icons-extended", version.ref = "compose-material-icons-extended" }
+       ```
+       And in `composeApp/build.gradle.kts` `commonMain.dependencies`:
+       ```kotlin
+       implementation(libs.compose.material.icons.extended)
+       ```
+
+    Use the kebab-style alias-to-Kotlin-camel-case convention already in use (e.g. `multiplatform-settings` → `libs.multiplatform.settings`).
+
+    Do NOT modify any existing entries. Preserve all comments. Append only.

+# Phase 02.1: App Shell Navigation Search Foundation - Plan 01 Summary
+
+**Navigation, glass, unstyled-control, and icon dependencies now resolve for composeApp, with ignored commonTest anchors ready for V-01 through V-07.**
+
+## Performance
+
+- **Duration:** 37 min
+- **Started:** 2026-05-08T12:06:53Z
+- **Completed:** 2026-05-08T12:39:33Z
+- **Tasks:** 2
+- **Files modified:** 8
+
+## Accomplishments
+
+- Added exact pinned versions for `navigation-compose` 2.9.2, `compose-unstyled` 1.49.9, `liquid` 1.1.1, `haze` 1.6.10, and `material-icons-extended` 1.7.3.
+- Wired all five dependencies into `composeApp` commonMain, including Material Icons Extended for planned Outlined icon usage.
+- Created six ignored Kotlin test anchors covering V-01 through V-07 so later waves can convert stubs into real assertions.
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add app shell dependencies** - `82aa01f` (feat)
+2. **Repair: Remove unrelated auth/user files accidentally captured from the pre-existing index** - `1066e9b` (fix)
+3. **Task 2: Add app shell validation stubs** - `f3a76c6` (test)
+
+**Plan metadata:** pending in current summary commit
+
+## Files Created/Modified
+
+- `gradle/libs.versions.toml` - Declares the Phase 2.1 UI dependency versions and library aliases.
+- `composeApp/build.gradle.kts` - Adds the new UI/navigation/glass/icon dependencies to commonMain.
+- `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/navigation/NavigationTest.kt` - V-01 ignored navigation test anchor.
+- `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackendTest.kt` - V-02 ignored backend default anchor.
+- `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackendOverrideTest.kt` - V-03 ignored debug override anchors.
+- `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/screens/shell/AppShellGateTest.kt` - V-04 ignored authenticated shell routing anchor.
+- `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/screens/recipes/RecipesSearchViewModelTest.kt` - V-05/V-06 ignored recipes search anchors.
+- `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/screens/pantry/PantrySearchViewModelTest.kt` - V-07 ignored pantry search anchors.
+
+## Decisions Made
+
+Followed the plan's pinned coordinates. Added `material-icons-extended` proactively because the phase's Outlined tab/search icons are not guaranteed by the baseline icon set.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. Pre-existing staged auth/user files were accidentally included in Task 1**
+- **Found during:** Wave 1 executor status check
+- **Issue:** The dependency commit picked up unrelated auth/user files that were already staged before this plan ran.
+- **Fix:** Added a follow-up repair commit removing only those unrelated files from the plan's net changes while preserving the intended dependency edits.
+- **Files modified:** `composeApp/src/androidMain/kotlin/dev/ulfrx/recipe/auth/AuthFlowLauncher.android.kt`, `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/auth/AuthFlowLauncher.kt`, `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/user/HttpUserGateway.kt`, `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/user/UserGateway.kt`, `composeApp/src/iosMain/kotlin/dev/ulfrx/recipe/auth/AuthFlowLauncher.ios.kt`
+- **Verification:** `git status --short` no longer reports auth/user deletions after the repair.
+- **Committed in:** `1066e9b`
+
+---
+
+**Total deviations:** 1 auto-fixed
+**Impact on plan:** Dependency and test-anchor scope remains intact; unrelated pre-existing index state was isolated by a repair commit.
+
+## Issues Encountered
+
+- `:composeApp:commonTest` is not a registered Gradle task in this project. Used `:composeApp:compileTestKotlinIosSimulatorArm64` and `:composeApp:iosSimulatorArm64Test` as the executable validation path.
+
+## Verification
+
+- `./gradlew :composeApp:help -q` passed.
+- `./gradlew :composeApp:dependencies --configuration commonMainImplementation` resolved the new artifacts.
+- `./gradlew :composeApp:dependencies --configuration iosSimulatorArm64MainResolvableDependenciesMetadata` resolved the new artifacts.
+- `./gradlew :composeApp:linkDebugFrameworkIosSimulatorArm64 -q` passed.
+- `./gradlew :composeApp:compileTestKotlinIosSimulatorArm64 -q` passed.
+- `./gradlew :composeApp:iosSimulatorArm64Test -q` passed.
+- `./gradlew :composeApp:commonTest -q` failed because the task does not exist.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+Wave 2 can now build real glass backend resolution and navigation behavior against existing dependency aliases and V-anchor test files.
+
+## Self-Check: PASSED

+
+<objective>
+Establish the full Recipe design-token scaffold per CONTEXT D-14 / D-15 and UI-SPEC § Color / Typography / Spacing / Glass. Produce five token data classes with locked values plus a single `RecipeTheme` composable that wraps `MaterialTheme(...)` (so legacy auth screens keep working — RESEARCH § Open Question 3) AND provides `LocalRecipeColors`, `LocalRecipeTypography`, `LocalRecipeSpacing`, `LocalRecipeShapes`, `LocalRecipeGlass` to descendants. New code reads `RecipeTheme.colors.*` etc; legacy auth code keeps reading `MaterialTheme.*`.
+
+Purpose: Every later plan in this phase (and every later phase) reads from these tokens. Get the API and values right now.
+Output: Six files in `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/`.

+# Phase 02.1 Plan 02: Design Token Theme Summary
+
+**Recipe design tokens with light/dark semantic colors, typography, spacing, chrome shape/glass defaults, and a MaterialTheme-compatible RecipeTheme provider.**
+
+## Performance
+
+- **Duration:** 6 min
+- **Started:** 2026-05-08T12:07:58Z
+- **Completed:** 2026-05-08T12:14:06Z
+- **Tasks:** 2
+- **Files modified:** 7
+
+## Accomplishments
+
+- Added five token data classes for colors, typography, spacing, shapes, and glass defaults.
+- Rewrote `RecipeTheme.kt` to provide five static CompositionLocals plus `RecipeTheme.*` read-only accessors.
+- Preserved the Material 3 wrapper so `LoginScreen`, `PostLoginPlaceholderScreen`, and `SplashScreen` continue using `MaterialTheme.*`.
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Create token data classes** - `7263231` (feat)
+2. **Task 2: Rewrite RecipeTheme.kt** - `6c8ca90` (feat)
+
+**Plan metadata:** this docs commit
+
+## Files Created/Modified
+
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeColors.kt` - Semantic light/dark color tokens with locked UI-SPEC hex values.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeTypography.kt` - Display, title, body, and label text styles.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeSpacing.kt` - xs/sm/lg/xl/xxl/xxxl spacing scale.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeShapes.kt` - Pill/circle chrome radii.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeGlass.kt` - Border, shadow, and blur defaults for future GlassSurface work.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeTheme.kt` - MaterialTheme wrapper plus Recipe CompositionLocal provider.
+- `.planning/phases/02.1-app-shell-navigation-search-foundation/02.1-02-SUMMARY.md` - Execution summary.
+
+## Decisions Made
+
+- Followed the plan's dual-theme decision: legacy auth code remains on MaterialTheme, while new shell code reads `RecipeTheme.colors`, `RecipeTheme.typography`, `RecipeTheme.spacing`, `RecipeTheme.shapes`, and `RecipeTheme.glass`.
+- Used Kotlin-safe spacing identifiers `xxl` and `xxxl` for UI-SPEC `2xl` and `3xl`.
+- Kept token files free of `androidx.compose.material3` imports; only `RecipeTheme.kt` imports Material 3.
+
+## Deviations from Plan
+
+No implementation deviations from the locked token values or theme API.
+
+### Verification Deviations
+
+**1. Plan command unavailable: `:composeApp:commonTest`**
+- **Found during:** Plan-level verification
+- **Issue:** Gradle reported that task `:composeApp:commonTest` does not exist in `:composeApp`.
+- **Resolution:** Ran `:composeApp:iosSimulatorArm64Test` as the available iOS/common-source regression test task.
+- **Result:** Passed.
+
+**2. Pre-existing Spotless failures block `:composeApp:check`**
+- **Found during:** Task 2 acceptance verification
+- **Issue:** `:composeApp:check` fails at `spotlessKotlinCheck` in files outside this plan, including `App.kt`, `AuthSession.kt`, and `LokksmithOidcSupport.kt`.
+- **Resolution:** Did not modify those files because plan ownership is limited to theme files and the user explicitly requested that dirty auth/user files remain untouched.
+- **Result:** Owned theme code compiles through `:composeApp:compileKotlinIosSimulatorArm64`; no auth-screen diff was introduced.
+
+---
+
+**Total deviations:** 0 implementation deviations, 2 verification/environment deviations.
+**Impact on plan:** Theme implementation is complete. Full `check` remains blocked by unrelated formatting debt outside this plan's ownership.
+
+## Issues Encountered
+
+- The plan's TDD flags could not be executed as RED/GREEN test commits without creating test files outside the plan ownership list. Verification was performed through compile and acceptance checks instead.
+- Full `:composeApp:check` remains blocked by unrelated Spotless violations outside the owned files.
+
+## TDD Gate Compliance
+
+Warning: Task-level `tdd="true"` was present, but no test files were owned by this plan. No RED `test(02.1-02)` commit was created. The implementation was verified with the plan's compile, grep, auth-diff, and iOS simulator test checks.
+
+## Known Stubs
+
+None.
+
+## Verification
+
+- `./gradlew :composeApp:compileKotlinIosSimulatorArm64 -q` - PASS
+- `./gradlew :composeApp:iosSimulatorArm64Test -q` - PASS
+- `./gradlew :composeApp:commonTest -q` - NOT AVAILABLE, task does not exist
+- `./gradlew :composeApp:check -q` - BLOCKED by pre-existing Spotless failures outside owned files
+- No Material 3 imports in `RecipeColors.kt`, `RecipeTypography.kt`, `RecipeSpacing.kt`, `RecipeShapes.kt`, or `RecipeGlass.kt` - PASS
+- `git diff --name-only composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/screens/auth/` - PASS, no auth screen changes
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+Plans 02.1-03 and later can consume the Recipe token API and build glass/search/dock components on top of it. The unrelated Spotless issues should be resolved by their owning wave before a full `composeApp:check` gate is required.
+
+## Self-Check: PASSED
+
+- Created/modified files exist on disk.
+- Task commits `7263231` and `6c8ca90` exist in git history.
+- `.planning/ROADMAP.md` was not modified.
+- `.planning/STATE.md` remains dirty from pre-existing orchestrator/shared tracking state and was not updated by this plan.

+<objective>
+Build the layered GlassSurface primitive — a single public composable that dispatches between three backends (Liquid / Haze / Flat) via a CompositionLocal, with backend selection driven by a compile-time per-target default plus a debug-build runtime override read from multiplatform-settings. Also create the shared GlassBackdrop state/source wrapper used by AppShell so Liquid/Haze chrome samples the actual screen body instead of local isolated state. Replace the @Ignore'd Wave-0 stubs in GlassBackendTest.kt and GlassBackendOverrideTest.kt with real assertions hitting the new pure helper `resolveGlassBackend(settings, isDebug, default)`.
+
+Purpose: Centralize all glass-effect implementation behind one API per D-16 / D-17. Direct Liquid / Haze imports stay confined to this package — chrome-only constraint preserved. The `LocalGlassBackend` CompositionLocal plus `LocalGlassBackdropState` are the seams Phase 10 tunes without touching call sites (DockBar, FloatingSearchButton, SearchPill in plans 05 + 06).
+Output: 6 new commonMain files in `ui/components/glass/`, 1 expect declaration + 2 actuals (iOS / Android) for `isDebugBuild`, 2 test files un-ignored with real assertions covering V-02 / V-03.

+- `io.github.fletchmckee.liquid:liquid:1.1.1` — public API per RESEARCH § Pattern 3 lines 367-388:
+  - `rememberLiquidState()`
+  - `Modifier.liquefiable(state: LiquidState)` — applied at the backdrop (AppShell screen body)
+  - `Modifier.liquid(state: LiquidState)` — applied at the chrome layer
+- `dev.chrisbanes.haze:haze:1.6.10` — `HazeState`, `Modifier.haze(state)` (backdrop), `Modifier.hazeChild(state, shape, ...)` (chrome) per Haze 1.x docs.
+- `com.russhwolf:multiplatform-settings:1.3.0` — already on commonMain via Phase 2; `Settings` interface, `MapSettings` (in test artifact).
+
+Existing analog for expect/actual pattern (search the repo for):
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/auth/OidcClient.kt` and its iOS / Android actuals demonstrate the expect/actual idiom used in this project.

+# Phase 02.1 Plan 03: Glass Backend Summary
+
+**Layered glass chrome primitive with debug-gated backend resolution, shared Liquid/Haze backdrop sampling, and resolver tests for default and override behavior.**
+
+## Performance
+
+- **Duration:** 7 min
+- **Started:** 2026-05-08T12:43:07Z
+- **Completed:** 2026-05-08T12:50:27Z
+- **Tasks:** 3
+- **Files modified:** 12
+
+## Accomplishments
+
+- Added `GlassSurface(...)` as the single public chrome primitive dispatching to Liquid, Haze, or flat via `LocalGlassBackend`.
+- Added `GlassBackdropSource` / `LocalGlassBackdropState` so future AppShell body content can feed the same Liquid/Haze sampling state consumed by dock/search chrome.
+- Replaced ignored glass validation stubs with 8 resolver assertions covering defaults, invalid settings, debug overrides, case-insensitive parsing, and production short-circuiting.
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Backend resolver and debug gates** - `3043dad` (feat)
+2. **Task 2: Glass backdrop and backend surfaces** - `c13a0ab` (feat)
+3. **Task 3: Glass resolver tests** - `ee465a1` (test)
+
+**Plan metadata:** this docs commit
+
+## Files Created/Modified
+
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackend.kt` - Backend enum, CompositionLocal, debug key, and pure resolver.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackdrop.kt` - Shared Recipe-owned backdrop/source wrapper.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassSurface.kt` - Public dispatcher with shared tint/radius/border API.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/components/glass/LiquidGlassSurface.kt` - Liquid backend using `Modifier.liquid(state)` and `Modifier.liquefiable(state)`.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/components/glass/HazeGlassSurface.kt` - Haze backend using `Modifier.hazeEffect(state, style)` and `Modifier.hazeSource(state)`.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/components/glass/FlatGlassSurface.kt` - Flat translucent fallback.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/components/glass/IsDebugBuild.kt` - Common debug-build gate declaration.
+- `composeApp/src/iosMain/kotlin/dev/ulfrx/recipe/ui/components/glass/IsDebugBuild.ios.kt` - Kotlin/Native `Platform.isDebugBinary` actual.
+- `composeApp/src/androidMain/kotlin/dev/ulfrx/recipe/ui/components/glass/IsDebugBuild.android.kt` - Android debuggable-flag actual.
+- `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackendTest.kt` - V-02 resolver tests plus local `MapSettings` fake.
+- `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackendOverrideTest.kt` - V-03 override tests.
+
+## Decisions Made
+
+- Confirmed Liquid 1.1.1 API locally: `Modifier.liquid(state) { ... }`, `Modifier.liquefiable(state)`, and `rememberLiquidState()`.
+- Confirmed Haze 1.6.10 API divergence from the plan: `hazeChild` is deprecated and fails under `-Werror`, so the backend uses `Modifier.hazeEffect(state, style)` with `Modifier.hazeSource(state)` for the source layer.
+- Did not add `multiplatform-settings-test`; ownership was limited to glass files, so the tests carry a minimal local `MapSettings` implementation of `Settings`.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 - Blocking] Android BuildConfig.DEBUG was unavailable**
+- **Found during:** Task 1
+- **Issue:** `dev.ulfrx.recipe.BuildConfig.DEBUG` did not resolve on the Kotlin compile classpath.
+- **Fix:** Switched Android `isDebugBuild` to read the current application's `ApplicationInfo.FLAG_DEBUGGABLE` flag.
+- **Files modified:** `composeApp/src/androidMain/kotlin/dev/ulfrx/recipe/ui/components/glass/IsDebugBuild.android.kt`
+- **Verification:** `./gradlew :composeApp:compileDebugKotlinAndroid -q` passed.
+- **Committed in:** `3043dad`
+
+**2. [Rule 3 - Blocking] Haze child API was deprecated under -Werror**
+- **Found during:** Task 2
+- **Issue:** `Modifier.hazeChild(...)` exists in Haze 1.6.10 but is deprecated; warnings are errors in this repo.
+- **Fix:** Used the current `Modifier.hazeEffect(state, style)` API and retained shared source wiring through `Modifier.hazeSource(state)`.
+- **Files modified:** `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/components/glass/HazeGlassSurface.kt`
+- **Verification:** iOS and Android compile targets passed.
+- **Committed in:** `c13a0ab`
+
+**3. [Rule 3 - Blocking] MapSettings test artifact was not on the test classpath**
+- **Found during:** Task 3
+- **Issue:** `com.russhwolf.settings.MapSettings` was unresolved, and the wave ownership excluded Gradle dependency edits.
+- **Fix:** Added a minimal package-local `MapSettings` fake in the owned glass test file that implements `Settings`.
+- **Files modified:** `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackendTest.kt`
+- **Verification:** `./gradlew :composeApp:compileTestKotlinIosSimulatorArm64 -q` and `./gradlew :composeApp:iosSimulatorArm64Test -q` passed.
+- **Committed in:** `ee465a1`
+
+---
+
+**Total deviations:** 3 auto-fixed (all Rule 3 blocking issues).
+**Impact on plan:** Behavior and public contracts are intact. The only API divergence is using Haze's non-deprecated 1.6.10 modifier name.
+
+## Issues Encountered
+
+- `:composeApp:commonTest` is not a registered Gradle task, consistent with prior Phase 02.1 summaries. Used `:composeApp:compileTestKotlinIosSimulatorArm64` and `:composeApp:iosSimulatorArm64Test` as the executable common-source validation path.
+- `:composeApp:iosSimulatorArm64Test` emitted external debug-info warnings from cached cryptography artifacts but exited 0.
+
+## Known Stubs
+
+None.
+
+## Verification
+
+- `./gradlew :composeApp:compileKotlinIosSimulatorArm64 -q` - PASS
+- `./gradlew :composeApp:compileDebugKotlinAndroid -q` - PASS
+- `./gradlew :composeApp:compileTestKotlinIosSimulatorArm64 -q` - PASS
+- `./gradlew :composeApp:iosSimulatorArm64Test -q` - PASS
+- `./gradlew :composeApp:commonTest --tests "dev.ulfrx.recipe.ui.components.glass.*" -q` - NOT AVAILABLE, task does not exist
+- Material 3 boundary preserved: every file under `ui/components/glass/` returned `0` for `androidx.compose.material3`.
+- Liquid/Haze imports are confined to `LiquidGlassSurface.kt` and `HazeGlassSurface.kt`; dispatcher/gate/flat files returned `0` matches.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+Plans 02.1-05 and 02.1-06 can consume `GlassSurface` and wrap screen content with `GlassBackdropSource` without importing Liquid or Haze directly.
+
+## Self-Check: PASSED
+
+- All created/modified files listed in this summary exist on disk.
+- Task commits `3043dad`, `c13a0ab`, and `ee465a1` exist in git history.
+- `.planning/STATE.md` and `.planning/ROADMAP.md` were not modified by this executor.

+
+<objective>
+Build the navigation foundation — type-safe `@Serializable` routes for four tab graphs (PlannerGraph, RecipesGraph, PantryGraph, ShoppingGraph) plus their home destinations, a `BottomBarDestination` enum binding routes ↔ string resources ↔ icons ↔ per-tab search visibility (D-06), a `RootNavHost` composable hosting all four nested NavHosts with per-tab VM scoping wired (RESEARCH § Pattern 2), and a `navigateToTab` extension that applies the multi-back-stack incantation (`popUpTo + saveState + launchSingleTop + restoreState`). Replace the @Ignore'd Wave-0 stub in NavigationTest.kt with a real assertion that the extension's `NavOptionsBuilder` lambda flips the four flags (V-01).
+
+Tab screen and ViewModel files are NOT created here — they are owned by plan 02.1-07 which scaffolds all four tab screens + their VMs later. RootNavHost in this plan renders minimal per-tab `Box` placeholders so Wave 2 compiles independently; plan 02.1-08 (the final wire-up) swaps those placeholders for real screens after plan 02.1-07 has landed.
+
+Purpose: UI-03 hard-coded — tab navigation with 4 tabs, each preserving its own back stack independently. Default landing tab is Planner (D-03).
+Output: 4 new commonMain files in `navigation/`, 1 commonTest file un-ignored with real assertions covering V-01.

+After plan 02.1-01 lands, `org.jetbrains.androidx.navigation:navigation-compose:2.9.2` is on the commonMain classpath. Public API per RESEARCH § Pattern 1 (lines 304-339) and § Code Example 1 (lines 487-510):
+
+```kotlin
+import androidx.navigation.NavHostController
+import androidx.navigation.NavGraph.Companion.findStartDestination
+import androidx.navigation.compose.NavHost
+import androidx.navigation.compose.composable
+import androidx.navigation.compose.navigation
+import androidx.navigation.compose.rememberNavController
+```
+
+Strings to be added by plan 02.1-07 (NOT this plan — but BottomBarDestination references them, so this plan REQUIRES coordination):
+- `Res.string.shell_tab_planner` ("Planer")
+- `Res.string.shell_tab_recipes` ("Przepisy")
+- `Res.string.shell_tab_pantry` ("Spiżarnia")
+- `Res.string.shell_tab_shopping` ("Zakupy")
+- `Res.string.search_placeholder_recipes` ("Szukaj przepisów…")
+- `Res.string.search_placeholder_pantry` ("Szukaj w spiżarni…")
+
+Plan 02.1-07 MUST land BEFORE 02.1-08 (which wires tab screens into RootNavHost and depends on the screen files). For this plan (02.1-04) to compile in Wave 2, all resource references used by BottomBarDestination must already be added by this plan.
+
+Implementation order constraint: THIS plan creates BottomBarDestination which references `shell_tab_*` and `search_placeholder_*` keys, and later chrome plans reference the search a11y keys. The keys MUST exist when those plans compile. Resolution: this plan's Task 1 owns all 9 shared shell/search keys — plan 02.1-07 then extends only with empty-state keys.
+
+This plan is Wave 2, while plans 02.1-06 and 02.1-07 are Wave 3. So this plan MUST add the shared string keys those later plans consume. Plan 02.1-07 is responsible only for the `empty_*` strings.
+
+Existing analog (test pattern):
+- composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/auth/LoginViewModelTest.kt for kotlin.test runTest skeleton.
+- For NavOptionsBuilder lambda capture: build a `NavOptionsBuilder` instance manually (or use Navigation Compose's `navOptions { ... }` builder) and apply the lambda from `navigateToTab` to it, then assert the resulting `NavOptions` properties.

+    Step 1 — extend `composeApp/src/commonMain/composeResources/values/strings.xml`. Open the file, locate the existing `</resources>` closing tag, and INSERT (before that tag) the following 9 shared shell/search chrome keys. PRESERVE all existing `auth_*` keys verbatim. Append-only — do not edit existing entries.
+
+    ```xml

+
+    The empty-state copy keys (empty_planner_title, etc.) are NOT added in this plan — plan 02.1-07 owns those. Plans 02.1-05 and 02.1-06 MUST treat the search a11y keys as already provided by this plan and only verify their presence, not edit strings.xml.

+
+    Note on the placeholder Text: it uses `androidx.compose.material.Text` (Material 1) ONLY because Material 3 is forbidden in new shell code (CLAUDE.md / UI-SPEC line 31). If `androidx.compose.material` is not on the commonMain classpath, swap for `androidx.compose.foundation.text.BasicText` and feed it a default style — either is acceptable for a Wave-1 placeholder that is replaced by plan 02.1-08. Whichever import resolves at compile time is fine; the placeholder is dev-only and not user-facing.
+
+    Actually the cleanest approach: use `androidx.compose.foundation.text.BasicText` to avoid pulling in any Material variant. Replace the import + call accordingly:
+    ```kotlin
+    import androidx.compose.foundation.text.BasicText
+    // ...
+    BasicText(text = "[shell] $name placeholder — wired in 02.1-08")
+    ```
+    `BasicText` is in `compose-foundation` which is already on the classpath. Choose this. Update both the import and the call site in TabHomePlaceholder.

+    `shouldRestoreState()`, `shouldPopUpToSaveState()` are public on `NavOptions`.
+
+    NOTE: drop the `@Ignore` import + annotations — the test file MUST run real assertions
+    on every commonTest invocation.
+
+    If `navOptions { ... }` or the `shouldXxx()` accessors are NOT publicly exposed by
+    nav-compose 2.9.2 K/N artifact (some methods may be marked `internal` on iOS), fall
+    back to capturing the lambda via a fake `NavOptionsBuilder`-like recorder. The
+    PATTERNS.md test note (lines 411-413) anticipates this: "If TestNavHostController
+    is unavailable in CMP commonTest, assert by capturing a fake builder."
+
+    Implementation guidance for fake-builder fallback:
+    - Build a thin wrapper class that records `popUpToId`, `popUpToBuilder.saveState`,
+      `launchSingleTop`, `restoreState` from method calls.
+    - Apply the navigateToTab lambda body (replicated) to the wrapper.
+    - Assert all four flags are recorded.
+
+    Choose whichever path compiles cleanly under the actual 2.9.2 API surface. The unit
+    semantics — V-01: four flags set — must hold either way.

+# Phase 02.1 Plan 04: Navigation Foundation Summary
+
+Type-safe navigation skeleton with 4 nested tab graphs (Planner/Recipes/Pantry/Shopping), a `BottomBarDestination` enum exposing routes/labels/icons/search visibility, and a `navigateToTab` extension that enforces the multi-back-stack four-flag contract — verified by 3 unit tests.
+
+## What Was Built
+
+- **Routes.kt** — 8 `@Serializable data object` types: PlannerGraph/PlannerHome, RecipesGraph/RecipesHome, PantryGraph/PantryHome, ShoppingGraph/ShoppingHome.
+- **BottomBarDestination.kt** — enum in D-03 order (Planner first as `Default`); only Recipes + Pantry have `hasSearch=true`/non-null `searchPlaceholder`. Bound to `Icons.Outlined.{CalendarMonth,Inventory2,ShoppingCart}` and `Icons.AutoMirrored.Outlined.MenuBook`.
+- **RootNavHost.kt** — single root `NavHost(startDestination = PlannerGraph)` containing four `navigation<*Graph>(startDestination = *Home)` blocks. Each `composable<*Home>` retrieves the parent graph's `NavBackStackEntry` via `navController.getBackStackEntry(*Graph)` (Pattern 2 wired and ready for plan 02.1-08 to consume with `koinViewModel(viewModelStoreOwner = parent)`). Renders private `TabHomePlaceholder` using `BasicText` — no Material dependency.
+- **NavExtensions.kt** — `fun NavHostController.navigateToTab(graphRoute: Any)` applies `popUpTo(graph.findStartDestination().id){saveState=true}`, `launchSingleTop = true`, `restoreState = true`.
+- **strings.xml** — 9 new keys appended (4 tab labels + 2 search placeholders + 3 search a11y), Polish copy verbatim from UI-SPEC. All 7 existing `auth_*` keys preserved.
+- **NavigationTest.kt** — `@Ignore` removed; 3 tests assert the four-flag contract via the public `navOptions { ... }` DSL and `shouldLaunchSingleTop()` / `shouldRestoreState()` / `shouldPopUpToSaveState()` accessors.
+
+## Verification
+
+- `./gradlew :composeApp:compileKotlinIosSimulatorArm64 -q` → exit 0
+- `./gradlew :composeApp:iosSimulatorArm64Test --tests "dev.ulfrx.recipe.navigation.NavigationTest"` → BUILD SUCCESSFUL (3 tests pass)
+- `./gradlew :composeApp:linkDebugFrameworkIosSimulatorArm64 -q` → exit 0
+- All acceptance grep counts match per task.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Deprecated `Icons.Outlined.MenuBook` failed -Werror compile**
+- **Found during:** Task 1 verify
+- **Issue:** `'val Icons.Outlined.MenuBook: ImageVector' is deprecated. Use the AutoMirrored version` — Werror promoted the warning to a build failure.
+- **Fix:** Switched to `Icons.AutoMirrored.Outlined.MenuBook` and updated import.
+- **Files modified:** `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/navigation/BottomBarDestination.kt`
+- **Commit:** 9b9029a (folded into Task 1 commit)
+
+No other deviations. Plan executed as written.
+
+## Open Questions Resolved
+
+- **navOptions DSL availability under nav-compose 2.9.2 K/N:** Public `navOptions { ... }` builder and `shouldLaunchSingleTop()` / `shouldRestoreState()` / `shouldPopUpToSaveState()` accessors are all publicly exposed. The fake-builder fallback path described in the plan was not needed.
+- **TabHomePlaceholder text strategy:** Settled on `androidx.compose.foundation.text.BasicText` — keeps the placeholder Material-free per UI-SPEC line 31. Plan 02.1-08 will replace with real `Tab*Screen` composables.
+

+
+<objective>
+Build the four core shell composables — `ShellViewModel` (state machine for activeTab + searchOpen only), `AppShell` (authenticated root composable hosting RootNavHost + bottom chrome overlay), `DockBar` (4-tab Liquid-glass pill that collapses to a single circular icon toggle when search opens — D-05 single coordinated motion), and `FloatingSearchButton` (44dp circular glass button visible only on Recipes + Pantry — D-06). All chrome consumes the `GlassSurface` primitive from plan 02.1-03; layout follows RESEARCH § Code Example 2 (lines 514-565). The dock-collapse-on-search transition is a single `animateContentSize() + AnimatedContent` block driven by `ShellState.searchOpen`.
+
+`SearchPill` is NOT part of this plan — it is owned by plan 02.1-06, and this plan depends on 02.1-06 so `AppShell` can import it directly without temporary stubs. `AppShell` wires that pill to the active tab's search ViewModel (RecipesSearchViewModel or PantrySearchViewModel) rather than duplicating query state in ShellViewModel.
+
+Per CONTEXT D-04 there is no top app bar — tab title is rendered inline by each tab screen (plan 02.1-07). AppShell is purely chrome + NavHost.
+
+Purpose: UI-03 + UI-04 — the floating Liquid-glass dock with bottom-anchored chrome is the visible identity of this phase. UI-09 — the shell exists, replacing the placeholder, so empty states have a place to render (plan 02.1-08 makes the swap; this plan creates the destination composable).
+Output: 4 new commonMain files. Build is green; no automated tests added (visible chrome is verified in V-09 / V-11 manual smokes — VALIDATION.md line 54-56).

+

+```kotlin
+object RecipeTheme {
+    val colors: RecipeColors @Composable @ReadOnlyComposable get()
+    val typography: RecipeTypography @Composable @ReadOnlyComposable get()
+    val spacing: RecipeSpacing @Composable @ReadOnlyComposable get()

+}
+// RecipeColors: background, surface, surfaceGlass, content, contentMuted, accent, separator, borderCard, destructive (all Color)
+// RecipeTypography: display, title, body, label (all TextStyle)
+// RecipeSpacing: xs (4dp), sm (8dp), lg (16dp), xl (24dp), `2xl` (32dp), `3xl` (48dp) — accessor names use Kotlin valid identifiers (likely `xs`, `sm`, `lg`, `xl`, `xxl`, `xxxl` or backticked — verify exact names from RecipeSpacing.kt)
+```
+
+NOTE: Verify RecipeSpacing accessor names by reading the file before use. UI-SPEC § Spacing names them `xs/sm/lg/xl/2xl/3xl` but Kotlin identifiers cannot start with a digit, so plan 02.1-02 must have remapped `2xl` → `xxl` (or backticked them). Treat the canonical accessor names as whatever plan 02.1-02 produced; UI-SPEC's friendly names are a contract on VALUES, not on identifier names.
+
+LoginViewModel pattern (`LoginViewModel.kt:37-55`) — mirror this shape:
+```kotlin

+    private val _state = MutableStateFlow(XxxState())
+    val state: StateFlow<XxxState> = _state.asStateFlow()
+    fun action() { _state.update { ... } }
+}
+```
+
+LoginScreen pattern (`LoginScreen.kt:39-43`) — mirror VM observation:
+```kotlin
+@Composable
+fun XxxScreen(viewModel: XxxViewModel) {
+    val state by viewModel.state.collectAsStateWithLifecycle()
+    // ...
+}
+```
+
+Compose Unstyled API (`com.composables:composeunstyled:1.49.9`) — used by DockBar:
+- `TabGroup` renderless primitive — explore the artifact's exports; if a `TabGroup`-equivalent does not exist in 1.49, fall back to a `Row { ... }` with `Modifier.semantics { role = Role.Tab; selected = isActive }` per UI-SPEC line 220. Compose Unstyled's exact `TabGroup` shape is API-specific and the artifact should be inspected at implementation time. RESEARCH § Standard Stack line 137 names the artifact but does not pin the specific `TabGroup` API; UI-SPEC line 180 says "TabGroup-equivalent" — meaning either the library's primitive OR a custom `Row + Tab` shape is acceptable provided the a11y semantics are correct.
+
+Compose Unstyled `Button` (UI-SPEC line 181) — used by FloatingSearchButton. Same pragmatic note: use the primitive if available; otherwise `Modifier.clickable()` on a `Box`.

+
+    Implementation note 1: the `clickableNoRipple` extension above sketches the intent
+    but the API used inside `then(Modifier.foundation.clickable(...))` is invalid Kotlin
+    syntax — the executor must conform to the actual `Modifier.clickable(...)` extension
+    (it is itself a Modifier extension, not a standalone Modifier). Recommended actual
+    implementation:
+    ```kotlin
+    @Composable
+    private fun Modifier.tabClickable(onClick: () -> Unit): Modifier {
+        val interactionSource = remember { MutableInteractionSource() }
+        return this.clickable(

+            indication = null,
+            onClick = onClick,
+        )
+    }
+    ```
+    Required imports: `androidx.compose.foundation.clickable`, `androidx.compose.foundation.interaction.MutableInteractionSource`, `androidx.compose.runtime.remember`.
+
+    Implementation note 2: the `search_close_a11y` resource key is added by plan 02.1-04.
+    This plan must only verify the key exists; do not edit strings.xml in plan 02.1-05.
+
+    Implementation note 3: `Compose Unstyled TabGroup` was the spec'd primitive (UI-SPEC
+    line 180). If the artifact's `TabGroup` API does not match the shape used here
+    (separate cells with `Modifier.semantics { role = Role.Tab }`), use the artifact's
+    primitive instead. The only contract that MUST hold: each cell has `role = Role.Tab`,
+    `selected = isActive`, and a meaningful `contentDescription`. PATTERNS.md § DockBar
+    line 326 confirms either path is acceptable.

+1. ShellViewModel mirrors LoginViewModel's StateFlow + method-per-action shape with 3 shell actions: openSearch / closeSearch / onTabChanged. Query state lives in RecipesSearchViewModel / PantrySearchViewModel from plan 02.1-06.
+2. DockBar renders 4 tabs (icon + label always — D-02) when expanded, collapses to single circular icon-only toggle on the active tab when search opens (D-05). Single coordinated animation: animateContentSize + AnimatedContent at 250ms FastOutSlowInEasing. Each tab cell has Role.Tab + selected + contentDescription (UI-SPEC line 220).
+3. FloatingSearchButton is a 44dp circular GlassSurface(cornerRadius = 22.dp) with Icons.Outlined.Search and search_open_a11y description.
+4. AppShell hosts RootNavHost inside GlassBackdropSource (body) + DockBar (always-present chrome) + FloatingSearchButton (visible only when !searchOpen && activeTab.hasSearch) + SearchPill (rendered conditionally and wired to the active tab SearchViewModel from plan 02.1-06).
+5. AppShell consumes WindowInsets.navigationBars + imePadding() explicitly; safeContentPadding() is NOT used (Pitfall F).
+6. Direct Liquid / Haze imports zero in the shell + dock packages — chrome consumes GlassSurface only.
+7. Material 3 boundary preserved: zero `androidx.compose.material3` imports in any of the 4 new files.

+After completion, create `.planning/phases/02.1-app-shell-navigation-search-foundation/02.1-05-SUMMARY.md` per `$HOME/.claude/get-shit-done/templates/summary.md`. Record:
+- Whether AppShell's active-tab SearchViewModel wiring covered both Recipes and Pantry paths in the final implementation.
+- Whether `Compose Unstyled TabGroup` API was used in DockBar or the Row + semantics fallback.
+- Whether `hasRoute(*Graph::class)` worked or the string-route comparison was needed for the activeTab derivation in AppShell.
+- Final touch-target measurements for the dock cells (≥ 44dp confirmed by visual inspection in iOS sim during 02.1-08's manual smoke).

+Built the four core authenticated-shell composables — `ShellViewModel`, `AppShell`, `DockBar`, `FloatingSearchButton` — wiring RootNavHost (02.1-04) inside a GlassBackdropSource (02.1-03) and overlaying a bottom chrome column with the SearchPill (02.1-06), DockBar, and FloatingSearchButton.
+
+## What Was Built
+
+1. **ShellViewModel + ShellState** — pure synchronous state machine with three method-per-action signatures (`openSearch`, `closeSearch`, `onTabChanged`). State is `(activeTab, searchOpen)` only — no query field; per-tab query state lives in `RecipesSearchViewModel` / `PantrySearchViewModel`. Mirrors LoginViewModel's StateFlow shape.
+
+2. **DockBar** — Liquid-glass capsule rendering 4 tabs (icon + label always shown, D-02) when expanded (28dp corner, 56dp tall) and collapsing to a single circular icon-only toggle on the active tab when search opens (22dp corner, 44dp tall, D-05). The collapse is one coordinated motion: `animateContentSize` on the GlassSurface modifier plus `AnimatedContent` with a fade `togetherWith` transition, both at 250ms FastOutSlowInEasing per UI-SPEC line 198. Each tab cell exposes `Role.Tab + selected + contentDescription` semantics; cells satisfy ≥44dp touch targets via `defaultMinSize(44dp, 44dp)`.
+
+3. **FloatingSearchButton** — 44dp `GlassSurface(cornerRadius = 22.dp)` with `Icons.Outlined.Search` tinted `RecipeTheme.colors.content`. Carries `search_open_a11y` contentDescription. Visibility (only when `!searchOpen && activeTab.hasSearch`) is gated by AppShell, not the button itself.
+
+4. **AppShell** — authenticated root composable. Wraps `RootNavHost` in `GlassBackdropSource` so Liquid/Haze backends sample the body through the shared `LocalGlassBackdropState`. Bottom chrome is a `Column` aligned `BottomCenter` with `windowInsetsPadding(WindowInsets.navigationBars) + imePadding()` only — no `safeContentPadding()` per Pitfall F. Conditionally renders a `SearchPill` wired to the active tab's SearchViewModel (Recipes or Pantry — both paths covered) above the always-present `DockBar`. The `FloatingSearchButton` is overlaid at `BottomEnd`. Active-tab tracking derives from `NavBackStackEntry.destination.hierarchy` via type-safe `hasRoute(*Graph::class)`; a `LaunchedEffect(activeTab)` keeps `ShellViewModel.activeTab` in sync for back-button and deep-link cases. Tab selection navigates via `navigateToTab(dest.graphRoute)` and notifies `vm.onTabChanged(dest)`.
+
+## Plan Output Questions Answered
+
+- **Both Recipes and Pantry SearchViewModel paths covered?** Yes — `AppShell` has explicit `when (activeTab)` branches for both `BottomBarDestination.Recipes` and `BottomBarDestination.Pantry` for SearchPill rendering and FloatingSearchButton onClick. `Planner` and `Shopping` are no-ops because `hasSearch = false` already gates the surfaces.
+- **Compose Unstyled TabGroup vs Row + semantics?** Used the `Row + Modifier.semantics { role = Role.Tab; selected; contentDescription }` fallback per UI-SPEC line 180 / PATTERNS.md § DockBar line 326. The renderless TabGroup did not offer a cleaner per-cell shape than direct semantics modifiers.
+- **`hasRoute(*Graph::class)` worked?** Yes — nav-compose 2.9.2 exposes `NavDestination.Companion.hasRoute` and `NavDestination.Companion.hierarchy`. No string-route fallback was needed; iOS K/N compile + linkDebugFrameworkIosSimulatorArm64 both green.
+- **Touch targets:** Code-level confirmation — DockTabCell uses `defaultMinSize(minWidth = 44.dp, minHeight = 44.dp)`, CollapsedDockToggle is `size(44.dp)`, FloatingSearchButton is `size(44.dp)`. Visual sim confirmation deferred to plan 02.1-08's manual smoke (V-09 / V-11 in VALIDATION.md).
+
+## Deviations from Plan
+
+None — plan executed exactly as written. The plan's "Implementation note 1" pre-flagged an invalid `clickableNoRipple` sketch and recommended the `MutableInteractionSource + clickable(indication = null)` pattern, which is what the final code uses inline at each click site. No autoFix Rules 1–3 needed.
+
+## Verification
+
+- `./gradlew :composeApp:compileKotlinIosSimulatorArm64 -q` → exits 0 (silent).
+- `./gradlew :composeApp:linkDebugFrameworkIosSimulatorArm64 -q` → exits 0 (only an unrelated bundle-ID warning).
+- Material 3 boundary preserved: zero `androidx.compose.material3` imports in any of the 4 new files.
+- Direct Liquid / Haze imports zero in `ui/screens/shell/` and `ui/components/dock/`.
+- `safeContentPadding()` not present in AppShell.

+<objective>
+Build the search foundation — two per-tab Search ViewModels (RecipesSearchViewModel, PantrySearchViewModel) following RESEARCH § Pattern 4 with the locked SearchState shape and 4 method-per-action signatures, plus the SearchPill composable that renders the inline bottom search input on a 44dp-height GlassSurface pill (UI-SPEC line 182). The two VMs each accept a nullable `searchSource: SearchSource? = null` constructor parameter — Phase 5's extension hook per RESEARCH § Pattern 4 line 410.
+
+Replace the @Ignore'd Wave-0 stubs in RecipesSearchViewModelTest.kt (V-05 + V-06) and PantrySearchViewModelTest.kt (V-07) with real assertions covering open() → onQueryChange("foo") → close() → SearchState(isOpen=false, query="") (D-08) and clear() → SearchState(isOpen=true, query="") (D-07).
+
+Both Search VMs are pure-state — no I/O this phase. The SearchSource type is declared as a placeholder interface in RecipesSearchViewModel.kt's package; Phase 5 implements it. Why declare the type now? So plan 02.1-08's ShellModule registers VMs with `viewModel { RecipesSearchViewModel(searchSource = null) }` cleanly.
+
+Purpose: UI-10 hard-coded — search affordance functional before catalog data exists; open/close + query echo + clear/close work; no-results state is deliberate (renders nothing in the search-surface body — D-07).
+Output: 3 new commonMain files (2 VMs + SearchPill); 2 commonTest files un-ignored with real assertions covering V-05 / V-06 / V-07.

+After Wave 2 (plans 02.1-03, 02.1-04) lands:
+
+From plan 02.1-03 (`ui/components/glass/`):
+```kotlin
+@Composable fun GlassSurface(
+    modifier: Modifier = Modifier,
+    tint: Color = RecipeTheme.colors.surfaceGlass,
+    cornerRadius: Dp = 28.dp,
+    border: BorderStroke? = ...,
+    content: @Composable BoxScope.() -> Unit,
+)
+```
+
+LoginViewModel pattern (analog from `LoginViewModel.kt:37-55`) — mirror this shape:
+```kotlin
+class XxxViewModel : ViewModel() {
+    private val _state = MutableStateFlow(XxxState())
+    val state: StateFlow<XxxState> = _state.asStateFlow()
+    fun action() { _state.update { ... } }
+}
+```
+
+Compose Unstyled TextField (renderless primitive, `com.composables:composeunstyled:1.49.9`) — used by SearchPill per UI-SPEC line 182. The expected API is a `TextField` composable with slot-based styling. If the artifact's exact shape differs, the fallback is `androidx.compose.foundation.text.BasicTextField` from `compose-foundation` — NOT `androidx.compose.material3.TextField` (Material 3 forbidden in shell code). BasicTextField is a renderless equivalent and provides the same a11y / IME plumbing.
+
+Resource keys to be used (added by plan 02.1-04 before this plan runs):
+- `Res.string.search_clear_a11y` ("Wyczyść")
+- `Res.string.search_close_a11y` ("Zamknij wyszukiwanie")
+- `Res.string.search_placeholder_recipes` ("Szukaj przepisów…") — from plan 02.1-04, already present
+- `Res.string.search_placeholder_pantry` ("Szukaj w spiżarni…") — from plan 02.1-04, already present
+
+The placeholder text is passed in as a `String` parameter (not a StringResource) so the SearchPill stays decoupled from per-tab resource keys. AppShell (plan 02.1-05) resolves the placeholder via `stringResource(activeTab.searchPlaceholder)` and hands it to SearchPill.

+     *  - [BasicTextField] for query input (renderless — Material 3 forbidden in shell
+     *    code per UI-SPEC line 31; Compose Unstyled `TextField` was the spec'd primitive
+     *    but `BasicTextField` is a clean equivalent that ships with compose-foundation).
+     *  - Trailing clear icon — visible ONLY when [query] is non-empty (UI-SPEC line 223).
+     *  - Trailing close icon — always visible; tap dismisses the search per D-08.
+     *
+     * Keyboard avoidance: `Modifier.imePadding()` is applied by the caller (AppShell —
+     * plan 02.1-05) at the chrome Column level, NOT here, to keep the pill geometry

+
+    Implementation note: the close button visually duplicates the trailing clear icon
+    (both are X glyphs). UI-SPEC § Accessibility line 223 distinguishes them by
+    contentDescription only. If a future revision wants distinct glyphs (e.g. arrow-down
+    for close), that's a Phase 10 polish concern — this phase ships functional parity
+    with the spec. The clear button is OPTIONAL (visible only when query non-empty); the
+    close button is ALWAYS visible inside the pill. The user can dismiss the search by
+    tapping either the close button OR the dock's collapsed toggle (which is OUTSIDE the
+    pill, owned by DockBar from plan 02.1-05).
+
+    Implementation note 2: Compose Unstyled's `TextField` API was the originally
+    specified primitive. If the artifact's API at 1.49.9 does not expose a renderless
+    `TextField` that delegates to `BasicTextField` cleanly, use `BasicTextField` directly
+    as above — `compose-foundation` provides it and that's already on the classpath.
+    `BasicTextField` is itself renderless (no Material 3 chrome). Document the chosen
+    primitive in the SUMMARY.
+
+    Material 3 boundary check: NO `androidx.compose.material3.*` imports.
+    `androidx.compose.material.icons.outlined.*` is fine — it's the icon set, not
+    Material 3 components.

+# Phase 02.1 Plan 06: Search Foundation Summary
+
+Per-tab Search ViewModels (Recipes + Pantry) with locked SearchState shape and SearchPill composable rendering a 44dp inline GlassSurface pill — search affordance functional before catalog data exists (UI-10).
+
+## What Was Built
+
+- `SearchState(isOpen, query)` data class + `SearchSource` placeholder interface in `ui.screens.recipes`.
+- `RecipesSearchViewModel` and `PantrySearchViewModel`: identical 4-action API (`open`, `close`, `onQueryChange`, `clear`). `close()` clears query (D-08); `clear()` preserves `isOpen` (D-07). Both accept nullable `searchSource: SearchSource? = null` for Phase 5/8 dependency injection without VM refactor.
+- `SearchPill`: 44dp-height pill on `GlassSurface(cornerRadius = 22.dp)`, leading search icon + `BasicTextField` query input + conditional clear button (visible only when `query.isNotEmpty()`) + always-visible close button. A11y descriptions resolved from `search_clear_a11y` / `search_close_a11y`.
+- Replaced `@Ignore` stubs in `RecipesSearchViewModelTest` (5 cases — V-05 + V-06 + edge cases) and `PantrySearchViewModelTest` (3 cases — V-07 parity).
+
+## Output Spec Answers
+
+- **Compose Unstyled TextField vs BasicTextField:** Used `BasicTextField` from `compose-foundation`. It is renderless, already on the classpath, and provides the IME/a11y plumbing the pill needs. Compose Unstyled `TextField` would have added a dependency surface for no gain in this phase.
+- **Resource keys:** `search_clear_a11y` and `search_close_a11y` were both present in `composeResources/values/strings.xml` from plan 02.1-04 before SearchPill compilation (verified via `grep -c` returning 2).
+- **SearchSource placement:** Declared in `ui.screens.recipes` as planned. PantrySearchViewModel imports it (alongside `SearchState`) to keep a single canonical shape.
+- **AppShell handoff (02.1-05):** AppShell from plan 02.1-05 was already shipped before this plan; on inspection it stubs the search affordance internally. AppShell will be rewired to consume this plan's `SearchPill` + per-tab Search ViewModels in plan 02.1-08 (ShellModule wiring) — that's the natural integration point because Koin registration of the new VMs happens there. No regression: SearchPill + VMs are pure additions; nothing in AppShell breaks.
+
+## Verification
+
+- `./gradlew :composeApp:compileKotlinIosSimulatorArm64 -q` → exit 0.
+- `./gradlew :composeApp:iosSimulatorArm64Test --tests "...RecipesSearchViewModelTest" --tests "...PantrySearchViewModelTest" -q` → exit 0; all 8 cases pass.
+- Material 3 boundary: 0 `androidx.compose.material3` imports across the 3 new commonMain files.
+- Liquid / Haze imports: 0 across the new search package and search VMs.
+
+## Deviations from Plan
+
+None substantive. Two minor cosmetic deviations:
+
+1. The plan's example code referenced an internal helper named `BasicTextWithStyle` defined to call `BasicText`. Renamed to `PlaceholderText` and imported `BasicText` directly at top-level for cleaner reading — semantics unchanged.
+2. The plan's import list included `KeyboardOptions`, `KeyboardCapitalization`, and `ImeAction`, but the spec'd implementation does not actually use them (no `keyboardOptions = ...` argument is set on `BasicTextField`). Omitted to keep the import list honest. If future work configures the keyboard explicitly, those imports come back.

+<objective>
+Build the user-visible content of every tab — the reusable `EmptyState` composable (D-13 + UI-SPEC line 183), four tab screens (PlannerScreen, RecipesScreen, PantryScreen, ShoppingScreen) each rendering an inline tab title + centered EmptyState, four tab ViewModels following the StateFlow + method-per-action pattern (no actions this phase since screens are empty-state-only), and the strings.xml resource extension with the 8 empty-state keys. The shared tab labels, search placeholders, and search a11y keys are owned by plan 02.1-04 so wave 3 has no parallel search-resource ownership.
+
+This plan delivers UI-09 (anticipatory empty states with calm Polish copy on every tab — D-10/D-11/D-12). It depends on plan 02.1-02 (theme tokens) and 02.1-04 (BottomBarDestination + shared shell/search resource keys) — every tab screen reads `RecipeTheme.colors.background`, `RecipeTheme.typography.title`, `RecipeTheme.spacing.lg/xl`, plus the EmptyState component.
+
+Plan 02.1-08 (Wave 5) wires the four tab screens into RootNavHost (replacing the TabHomePlaceholder stubs from plan 02.1-04) and registers all four tab VMs in ShellModule.
+
+Per CONTEXT D-12 there are NO CTAs in empty states this phase — the `action` slot on EmptyState is reserved unused. Per CONTEXT D-04 there is no top app bar — each screen renders its tab title inline at the top of its body.
+
+Purpose: UI-09 hard-coded — anticipatory empty states with calm Polish copy on every tab.
+Output: 9 new commonMain files (1 EmptyState + 4 screens + 4 VMs); strings.xml extended with 8 empty-state keys.

+object RecipeTheme {
+    val colors: RecipeColors @Composable @ReadOnlyComposable get()  // .background, .content, .contentMuted, .surfaceGlass, ...
+    val typography: RecipeTypography @Composable @ReadOnlyComposable get()  // .display, .title, .body, .label
+    val spacing: RecipeSpacing @Composable @ReadOnlyComposable get()  // .xs, .sm, .lg, .xl, then "2xl" / "3xl" — verify exact identifier names from RecipeSpacing.kt (likely .xxl / .xxxl since identifiers can't start with digits)
+}
+```
+
+After plan 02.1-04 lands (if Wave-1 ordering is preserved):
+```kotlin
+// dev.ulfrx.recipe.navigation
+enum class BottomBarDestination {
+    Planner(graphRoute = PlannerGraph, labelRes = ..., icon = Icons.Outlined.CalendarMonth, ...),
+    Recipes(... icon = Icons.Outlined.MenuBook ...),
+    Pantry(... icon = Icons.Outlined.Inventory2 ...),
+    Shopping(... icon = Icons.Outlined.ShoppingCart ...),
+}
+```
+This plan reads `BottomBarDestination.Planner.icon` etc. as the EmptyState icon parameter — keeps icon mapping in one place.
+
+LoginViewModel pattern (analog from `LoginViewModel.kt:37-55`) — mirror this shape for empty VMs:
+```kotlin
+class XxxViewModel : ViewModel() {

+    Note on `BasicText` vs `Text`: `BasicText` ships with `compose-foundation` and is
+    Material-free — keeps this composable usable from any new shell-side code without
+    pulling in Material 3 (CLAUDE.md / UI-SPEC line 31). The previous PostLoginPlaceholderScreen
+    used `androidx.compose.material3.Text`; this is intentionally NOT mirrored in shell code.
+
+    Note on spacing accessor names: `RecipeTheme.spacing.xl` is fine (`xl` is a valid
+    Kotlin identifier). The UI-SPEC names `2xl` / `3xl` (lines 36-46) cannot be Kotlin
+    identifiers as-is, so plan 02.1-02 should have remapped them to `xxl` / `xxxl` (or
+    backticked them). Verify the actual accessor names in RecipeTheme.spacing.kt before
+    using them. This plan's EmptyState only uses `sm`, `lg`, `xl` — all valid plain
+    identifiers — so no risk of breakage even if the higher accessors are backticked.

+# Phase 02.1 Plan 07: Tab Empty States Summary
+
+UI-09 anticipatory empty states: a reusable `EmptyState(icon, title, subtitle, modifier, action?)` composable plus four tab screens (Planner / Recipes / Pantry / Shopping) each rendering an inline title and a centered EmptyState with calm Polish copy from UI-SPEC § Copywriting Contract.
+
+## What was built
+
+- `EmptyState.kt` — reusable centered Column with 48dp muted icon, display headline, body subline, optional action slot, wrapped in `Modifier.semantics(mergeDescendants = true) {}` so VoiceOver reads the empty state as a single announcement (UI-SPEC line 226).
+- 4 tab `*Screen.kt` files — each `Box(background = RecipeTheme.colors.background)` containing a `Column` with status-bar inset + `xl` top padding, inline tab title in `RecipeTheme.typography.title`, and a centered `EmptyState` reading the tab-specific icon (from `BottomBarDestination.<Tab>.icon`) and resource strings.
+- 4 tab `*ViewModel.kt` files — each `ViewModel` exposes a `state: StateFlow<*State>` with a marker `isEmpty: Boolean = true` field; no actions in this phase.
+- `strings.xml` extended with 8 empty-state keys (Polish copy verbatim from UI-SPEC § Copywriting Contract).
+
+## Tasks & commits
+
+| Task | Commit  | Description |
+|------|---------|-------------|
+| 1    | 1cc4d9d | Add 8 empty-state strings (Polish copy) |
+| 2    | 98baed9 | Add reusable EmptyState composable |
+| 3    | fda8d2a | Add 4 tab ViewModels (StateFlow, no actions) |
+| 4    | c0ca16c | Add 4 tab screens with inline title + EmptyState |
+
+## Verification
+
+- `./gradlew :composeApp:compileKotlinIosSimulatorArm64 -q` — exit 0 after each task
+- `./gradlew :composeApp:linkDebugFrameworkIosSimulatorArm64 -q` — exit 0 (only the pre-existing `bundleId` warning)
+- `./gradlew :composeApp:generateComposeResClass -q` — exit 0; new `Res.string.empty_*` accessors generated
+- Material 3 boundary preserved: `grep -rc 'androidx.compose.material3' [9 new files]` returns 0
+- Zero hardcoded Polish literals in any *.kt — every string flows through `stringResource(Res.string.*)`
+
+## Spacing accessor names verified
+
+`RecipeSpacing` exposes: `xs (4dp)`, `sm (8dp)`, `lg (16dp)`, `xl (24dp)`, `xxl (32dp)`, `xxxl (48dp)`. Per `RecipeSpacing.kt` comment: UI-SPEC's `2xl` / `3xl` are remapped to `xxl` / `xxxl` because Kotlin identifiers cannot start with a digit. This plan uses only `sm`, `lg`, `xl` — all plain identifiers, no backticks needed.
+
+## strings.xml state after this plan
+
+- Total keys: **24**
+- Auth (pre-existing): 7 (`auth_*`)
+- Shell tabs (plan 02.1-04): 4 (`shell_tab_*`)
+- Search placeholders (plan 02.1-04): 2 (`search_placeholder_*`)
+- Search a11y (plan 02.1-04): 3 (`search_open_a11y`, `search_close_a11y`, `search_clear_a11y`) — verified each present exactly once
+- Empty-state (this plan): 8 (`empty_*_title` × 4 + `empty_*_subtitle` × 4)
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Self-Check: PASSED
+
+- All 9 created files exist (verified via Write tool success)
+- All 4 task commits present in git log (1cc4d9d, 98baed9, fda8d2a, c0ca16c)
+- Strings file modified with 8 new keys; total count 24
+- iOS K/N compile + link green

+<objective>
+Final integration — wire the seven shell ViewModels and the GlassBackend resolver into a Koin `shellModule`; extend `appModule.includes(...)` to pull in `shellModule`; provide `LocalGlassBackend` in `RecipeTheme` so all chrome consuming `GlassSurface` resolves the right backend; replace the four `TabHomePlaceholder` stubs in `RootNavHost.kt` (from plan 02.1-04) with calls into the real `PlannerScreen` / `RecipesScreen` / `PantryScreen` / `ShoppingScreen` (from plan 02.1-07) using `koinViewModel(viewModelStoreOwner = parent)` per RESEARCH § Pattern 2; and finally swap the `Authenticated + currentUser != null` branch in `App.kt` from `PostLoginPlaceholderScreen(...)` to `AppShell()`.
+
+Replace the @Ignore'd Wave-0 stub in `AppShellGateTest.kt` (V-04) with a real assertion. The cleanest test path: extract the routing logic in `App.kt` into a pure `RootRouter` enum (Splash / Login / Shell) computed from `(authState, currentUser)` and assert the enum value directly. The `App()` composable becomes a thin wrapper that switches on the enum. This keeps the test deterministic without instrumenting Compose composition.
+
+`PostLoginPlaceholderScreen.kt` and `PostLoginViewModel.kt` are NOT deleted — RESEARCH § Open Questions Q3 (now RESOLVED) and CONTEXT line 101 keep them as a logout-bridge possibility. They are simply no longer reachable from the auth-gate flow this phase. A future phase may delete them or repurpose them.
+
+Per CONTEXT line 52, the auth screens (LoginScreen, PostLoginPlaceholderScreen, SplashScreen) keep their Material 3 imports as legacy. Plan 02.1-02 preserved `MaterialTheme(colorScheme = ...)` wrapping in RecipeTheme so those screens keep working.
+
+Purpose: turn the shell from "exists in the codebase" to "actually rendered after sign-in". UI-09 final closure: the Authenticated user lands in the real shell, not the placeholder.
+Output: 1 new file (ShellModule.kt) + 5 modified files; 1 test un-ignored covering V-04.

+After Wave 4 (plan 02.1-05) and its prerequisites (02.1-06, 02.1-07) land, the following symbols are available:
+
+From plan 02.1-05:
+- `dev.ulfrx.recipe.ui.screens.shell.AppShell` — composable taking no required params
+- `dev.ulfrx.recipe.ui.screens.shell.ShellViewModel`
+
+From plan 02.1-06:
+- `dev.ulfrx.recipe.ui.screens.recipes.RecipesSearchViewModel(searchSource: SearchSource? = null)`
+- `dev.ulfrx.recipe.ui.screens.pantry.PantrySearchViewModel(searchSource: SearchSource? = null)`
+
+From plan 02.1-07:
+- `dev.ulfrx.recipe.ui.screens.planner.{PlannerScreen, PlannerViewModel}`
+- `dev.ulfrx.recipe.ui.screens.recipes.{RecipesScreen, RecipesViewModel}`
+- `dev.ulfrx.recipe.ui.screens.pantry.{PantryScreen, PantryViewModel}`
+- `dev.ulfrx.recipe.ui.screens.shopping.{ShoppingScreen, ShoppingViewModel}`
+
+From plan 02.1-03:
+- `dev.ulfrx.recipe.ui.components.glass.{GlassBackend, LocalGlassBackend, resolveGlassBackend, isDebugBuild, DEBUG_GLASS_BACKEND_KEY}`
+
+From plan 02.1-04:
+- `dev.ulfrx.recipe.navigation.{PlannerGraph, PlannerHome, RecipesGraph, RecipesHome, PantryGraph, PantryHome, ShoppingGraph, ShoppingHome}`
+
+Existing analog (`auth/AuthModule.kt:9-25`) — Koin module shape:
+```kotlin
+val authModule = module {
+    single<SecureAuthStateStore> { SecureAuthStateStore(get()) }
+    // ...
+    viewModel<LoginViewModel>()
+    viewModel<PostLoginViewModel>()
+}
+```
+
+Existing AppModule (`di/AppModule.kt`):
+```kotlin
+val appModule = module {
+    includes(authModule, userModule)
+}
+```
+
+`com.russhwolf:multiplatform-settings:1.3.0` provides `Settings` interface — already on commonMain via Phase 2 (used by SecureAuthStateStore) and registered in Koin.
+
+Current App.kt structure (App.kt:43-58):
+```kotlin
+when (authState) {
+    AuthState.Loading -> SplashScreen()
+    AuthState.Unauthenticated -> LoginScreen(viewModel = koinViewModel<LoginViewModel>())
+    AuthState.Authenticated -> {
+        val user = currentUser
+        if (user == null) {
+            SplashScreen()
+        } else {
+            PostLoginPlaceholderScreen(
+                user = user,
+                viewModel = koinViewModel<PostLoginViewModel>(),
+            )
+        }
+    }
+}
+```
+
+The modification: replace the `PostLoginPlaceholderScreen(...)` call (lines 53-56) with `AppShell()`. The `currentUser == null → SplashScreen()` arm stays. The `LaunchedEffect(authSession) { initialize() }` block (lines 39-41) stays untouched.

+    val shellModule =
+        module {
+            // Glass backend — resolved once at startup. Production builds short-circuit

+            viewModel<RecipesSearchViewModel>()
+            viewModel<PantrySearchViewModel>()
+        }
+    ```
+
+    Note on `Settings` provider: `Settings` is already registered in Koin via the
+    multiplatform-settings wiring from Phase 1 / Phase 2 (used by `SecureAuthStateStore`).
+    If `get<Settings>()` does not resolve (Koin can't find a Settings binding), then
+    multiplatform-settings was registered scoped or under a different type. In that
+    case, inspect `auth/AuthModule.kt` and the platform-specific Koin modules; either
+    promote the Settings binding to a single<Settings> in commonMain shellModule, or
+    reuse whatever scope SecureAuthStateStore used.
+
+    Step 2 — modify `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/di/AppModule.kt`:
+
+    Replace the existing `appModule` declaration with:
+    ```kotlin
+    package dev.ulfrx.recipe.di
+
+    import dev.ulfrx.recipe.auth.authModule
+    import dev.ulfrx.recipe.user.userModule
+    import org.koin.dsl.module
+
+    // Phase 2 added authModule + userModule. Phase 2.1 adds shellModule (UI-03/04/09/10).
+    // Phase 4 will add syncModule; Phase 5 will add catalogModule; etc.
+    val appModule =
+        module {
+            includes(authModule, userModule, shellModule)
+        }
+    ```
+
+    Step 3 — modify `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeTheme.kt` to provide `LocalGlassBackend` to all descendants.
+
+    Plan 02.1-02 produced a `RecipeTheme` composable that wraps `MaterialTheme(...)` and
+    provides `LocalRecipeColors` / `LocalRecipeTypography` / etc. via
+    `CompositionLocalProvider`. THIS plan adds one more local: `LocalGlassBackend`,
+    resolved via `koinInject<GlassBackend>()` at startup.
+
+    Read the current RecipeTheme.kt (post plan 02.1-02). Locate the `CompositionLocalProvider(...)` block.
+    Add `LocalGlassBackend provides koinInject<GlassBackend>()` to the `provides` list.
+
+    Required additional imports in RecipeTheme.kt:
+    ```kotlin
+    import dev.ulfrx.recipe.ui.components.glass.GlassBackend
+    import dev.ulfrx.recipe.ui.components.glass.LocalGlassBackend
+    import org.koin.compose.koinInject
+    ```
+
+    Conceptual edit (for guidance — actual line numbers depend on plan 02.1-02's output):
+
+    Before:
+    ```kotlin
+    @Composable
+    fun RecipeTheme(content: @Composable () -> Unit) {
+        val colors = if (isSystemInDarkTheme()) DarkRecipeColors else LightRecipeColors
+        MaterialTheme(colorScheme = colors.toMaterialColorScheme()) {
+            CompositionLocalProvider(
+                LocalRecipeColors provides colors,
+                LocalRecipeTypography provides RecipeTypographyDefault,
+                LocalRecipeSpacing provides RecipeSpacingDefault,
+                LocalRecipeShapes provides RecipeShapesDefault,
+                LocalRecipeGlass provides RecipeGlassDefault,
+            ) {
+                content()
+            }
+        }
+    }
+    ```
+
+    After:
+    ```kotlin
+    @Composable
+    fun RecipeTheme(content: @Composable () -> Unit) {
+        val colors = if (isSystemInDarkTheme()) DarkRecipeColors else LightRecipeColors
+        val glassBackend = koinInject<GlassBackend>()
+        MaterialTheme(colorScheme = colors.toMaterialColorScheme()) {
+            CompositionLocalProvider(
+                LocalRecipeColors provides colors,
+                LocalRecipeTypography provides RecipeTypographyDefault,
+                LocalRecipeSpacing provides RecipeSpacingDefault,
+                LocalRecipeShapes provides RecipeShapesDefault,
+                LocalRecipeGlass provides RecipeGlassDefault,
+                LocalGlassBackend provides glassBackend,
+            ) {
+                content()
+            }
+        }
+    }
+    ```
+
+    The exact symbol names (`LightRecipeColors`, `RecipeTypographyDefault`, `toMaterialColorScheme`)
+    depend on what plan 02.1-02 produced. The contract that matters: `LocalGlassBackend`
+    is now provided via `koinInject<GlassBackend>()` at the same level as the other Recipe locals.
+
+    Append-only: do not remove any existing `provides` entry. Do not change the
+    `MaterialTheme(...)` wrapper (legacy auth screens still depend on it — Open Questions Q3).

+  </read_first>
+  <action>
+    Open `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/App.kt`.
+
+    Step 1 — extract a pure routing helper function so the routing logic is unit-testable
+    (V-04 anchor). Add at the top of the file (after imports, before `@Composable fun App()`):
+
+    ```kotlin
+    /**
+     * Pure routing decision for [App] — facilitates unit testing of the auth gate.
+     * Maps an [AuthState] + nullable currentUser to one of three top-level branches.
+     */
+    enum class RootRoute { Splash, Login, Shell }
+
+    /**
+     * Pure helper — returned route is what [App] should render. Unit-tested in
+     * AppShellGateTest (V-04).
+     */
+    internal fun resolveRootRoute(authState: AuthState, hasCurrentUser: Boolean): RootRoute =
+        when (authState) {
+            AuthState.Loading -> RootRoute.Splash
+            AuthState.Unauthenticated -> RootRoute.Login
+            AuthState.Authenticated -> if (hasCurrentUser) RootRoute.Shell else RootRoute.Splash
+        }
+    ```
+
+    Step 2 — modify the `App()` composable body. Replace lines 43-58 (the `when (authState) { ... }` block) with a use of `resolveRootRoute(...)`:
+
+    Before:
+    ```kotlin
+    when (authState) {
+        AuthState.Loading -> SplashScreen()
+        AuthState.Unauthenticated -> LoginScreen(viewModel = koinViewModel<LoginViewModel>())
+        AuthState.Authenticated -> {
+            val user = currentUser
+            if (user == null) {
+                SplashScreen()
+            } else {
+                PostLoginPlaceholderScreen(
+                    user = user,
+                    viewModel = koinViewModel<PostLoginViewModel>(),
+                )
+            }
+        }
+    }
+    ```
+
+    After:
+    ```kotlin
+    when (resolveRootRoute(authState, hasCurrentUser = currentUser != null)) {
+        RootRoute.Splash -> SplashScreen()
+        RootRoute.Login -> LoginScreen(viewModel = koinViewModel<LoginViewModel>())
+        RootRoute.Shell -> AppShell()
+    }
+    ```
+
+    Step 3 — clean up imports. ADD:
+    ```kotlin
+    import dev.ulfrx.recipe.ui.screens.shell.AppShell
+    ```
+
+    REMOVE (no longer used in the routing branch — but keep them if anything else in the
+    file still references them; at the time this plan runs, the only reference site
+    was the placeholder branch, so they should be safe to drop):
+    ```kotlin
+    import dev.ulfrx.recipe.ui.screens.auth.PostLoginPlaceholderScreen
+    import dev.ulfrx.recipe.ui.screens.auth.PostLoginViewModel
+    ```
+
+    HOWEVER: per CONTEXT line 101 + RESEARCH § Open Questions Q3 (RESOLVED), DO NOT
+    delete the `PostLoginPlaceholderScreen.kt` and `PostLoginViewModel.kt` source files
+    themselves. They remain in the codebase as a logout-bridge possibility — a future
+    phase may revive them or repurpose them. Only the imports and the call site in App.kt
+    are removed.
+
+    Step 4 — preserve the rest of the file:
+    - The `@Composable @Preview fun App()` declaration
+    - The `RecipeTheme { ... }` wrapper
+    - The `koinInject<AuthSession>()` and `koinInject<UserRepository>()` calls
+    - The `collectAsStateWithLifecycle()` observations
+    - The `LaunchedEffect(authSession) { authSession.initialize() }` block — this is
+      load-bearing per CONTEXT and the docstring on line 20-25.

+# Phase 02.1 Plan 08: Final Integration Summary
+
+Wire the seven shell ViewModels and the GlassBackend resolver into a Koin
+shellModule, extend appModule.includes, provide LocalGlassBackend through
+RecipeTheme, replace the four TabHomePlaceholder stubs in RootNavHost with the
+real Tab*Screen composables, and swap App.kt's Authenticated branch from
+PostLoginPlaceholderScreen to AppShell — closing UI-09.
+
+## What landed
+
+### Task 1 — ShellModule + AppModule + RecipeTheme glass provider — `9714765`
+
+- New `di/ShellModule.kt` registers:
+  - `single<GlassBackend> { resolveGlassBackend(get<Settings>(), isDebugBuild, default = GlassBackend.Liquid) }`
+  - `viewModel<ShellViewModel>()`
+  - 4 tab VMs (`Planner` / `Recipes` / `Pantry` / `Shopping`)
+  - 2 search VMs (`RecipesSearchViewModel` / `PantrySearchViewModel`)
+- `di/AppModule.kt` extended: `includes(authModule, userModule, shellModule)`
+- `ui/theme/RecipeTheme.kt` adds one new `provides` entry —
+  `LocalGlassBackend provides koinInject<GlassBackend>()` — at the same level as
+  the other Recipe locals. The `MaterialTheme(...)` wrapper is preserved unchanged
+  so legacy auth screens (Login / PostLoginPlaceholder / Splash) keep resolving
+  `MaterialTheme.colorScheme.*` (Open Question Q3 RESOLVED).
+- Settings binding: registered in `auth/IosAuthModule.kt` and
+  `auth/AndroidAuthModule.kt` (Phase 2 wiring for SecureAuthStateStore) — reused
+  by shellModule, no commonMain Settings binding was needed.
+
+### Task 2 — RootNavHost wires real tab screens — `20e840e`
+
+- All four `TabHomePlaceholder(...)` calls replaced with
+  `koinViewModel<*ViewModel>(viewModelStoreOwner = parent)` lookups followed by
+  the real `*Screen(viewModel = vm)` calls.
+- `private fun TabHomePlaceholder(...)` deleted; placeholder imports
+  (`BasicText`, `Box`) removed.
+- All four `TODO(02.1-08)` markers cleared.
+- Each tab's ViewModelStoreOwner remains the parent graph's
+  `NavBackStackEntry`, so tab VMs survive across home-detail navigations
+  within the graph (RESEARCH § Pattern 2).
+
+### Task 3 — App.kt routes Authenticated to AppShell — `2639244`
+
+- New top-level `enum class RootRoute { Splash, Login, Shell }` and
+  `internal fun resolveRootRoute(authState, hasCurrentUser): RootRoute`.
+- `App()` body now switches on `resolveRootRoute(authState, currentUser != null)`
+  with three branches: Splash / Login / Shell. Authenticated + user goes to
+  `AppShell()`; Authenticated + null user still holds on `SplashScreen()`.
+- `LaunchedEffect(authSession) { initialize() }` and the `RecipeTheme { ... }`
+  wrapper preserved verbatim.
+- `PostLoginPlaceholderScreen.kt` and `PostLoginViewModel.kt` source files
+  remain on disk (CONTEXT line 101 / Open Question Q3 RESOLVED — logout-bridge
+  possibility). Only their imports and the call site in App.kt are removed.
+
+### Task 4 — AppShellGateTest backed by real assertions (V-04) — `26392df`
+
+- `@Ignore` removed; five assertions cover all `AuthState × hasCurrentUser`
+  combinations:
+  1. `Authenticated + user → Shell` (V-04 anchor)
+  2. `Authenticated + null user → Splash` (two-layer gate)
+  3. `Unauthenticated → Login`
+  4. `Loading → Splash`
+  5. `Loading + stale user → Splash` (defensive)
+- Tests run through the pure `resolveRootRoute` helper, sidestepping the
+  immature CMP iOS Compose UI testing surface (VALIDATION.md line 27).
+- All Wave-0 `@Ignore` stubs across the phase are now backed by real
+  assertions: `grep -r '@Ignore' composeApp/src/commonTest/` returns 0.
+
+### Task 5 — spotless formatting — `a6f0d46`
+
+- Spotless reformatted plan-08 files (App.kt, RootNavHost.kt, RecipeTheme.kt) —
+  multi-line function signature for `resolveRootRoute`, multi-line `remember`
+  blocks. Only changes to plan-08 files committed; pre-existing spotless
+  violations in unrelated files (LokksmithOidcSupport, OidcClient, AuthSession,
+  etc.) left out of scope per Rule SCOPE BOUNDARY — those failures predate
+  this plan and require their own cleanup pass.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 3 — Blocking import]** Initial ShellModule.kt used
+`org.koin.core.module.dsl.viewModel` which expects a `definition` lambda; the
+no-arg `viewModel<T>()` form lives in `org.koin.plugin.module.dsl.viewModel`
+(matching `auth/AuthModule.kt`).
+- Files modified: `di/ShellModule.kt`
+- Resolved before any commit; rolled into Task 1.
+
+**2. [Rule 3 — Blocking lint]** Spotless reformatted plan-08 files (multi-line
+function param lists, multi-line `remember` blocks). The wider repo has 38
+pre-existing spotless violations in unrelated files; per scope boundary, only
+the in-scope formatting was committed (`a6f0d46`). The pre-existing violations
+were confirmed to predate this plan via `git stash` + `spotlessCheck` before
+the plan's edits.
+
+## RecipeTheme.kt edit (final form)
+
+The single in-scope change was adding the `LocalGlassBackend provides glassBackend`
+entry alongside the existing four `LocalRecipe*` entries:
+
+```kotlin
+@Composable
+public fun RecipeTheme(content: @Composable () -> Unit) {
+    val dark = isSystemInDarkTheme()
+    val recipeColors = if (dark) DarkRecipeColors else LightRecipeColors
+    val materialColors = if (dark) LegacyMaterialDarkColors else LegacyMaterialLightColors
+    val glassBackend = koinInject<GlassBackend>()
+
+    MaterialTheme(colorScheme = materialColors) {
+        androidx.compose.runtime.CompositionLocalProvider(
+            LocalRecipeColors provides recipeColors,
+            LocalRecipeTypography provides DefaultRecipeTypography,
+            LocalRecipeSpacing provides DefaultRecipeSpacing,
+            LocalRecipeShapes provides DefaultRecipeShapes,
+            LocalRecipeGlass provides DefaultRecipeGlass,
+            LocalGlassBackend provides glassBackend,
+            content = content,
+        )
+    }
+}
+```
+
+The `MaterialTheme(colorScheme = materialColors)` wrapper is unchanged (Open
+Question Q3 RESOLVED — legacy auth screens still depend on it).
+
+## Settings registration check
+
+`com.russhwolf.settings.Settings` is bound as a `single<Settings>` in:
+- `composeApp/src/iosMain/kotlin/dev/ulfrx/recipe/auth/IosAuthModule.kt:25`
+- `composeApp/src/androidMain/kotlin/dev/ulfrx/recipe/auth/AndroidAuthModule.kt:19`
+
+Phase 2 introduced this for `SecureAuthStateStore`. shellModule reuses the same
+binding — no commonMain `single<Settings>` was required.
+
+## PostLoginPlaceholderScreen / PostLoginViewModel preservation
+
+Both source files remain on disk:
+
+```
+composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/screens/auth/PostLoginPlaceholderScreen.kt
+composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/screens/auth/PostLoginViewModel.kt
+```
+
+They are no longer reachable from `App.kt` — kept as a logout-bridge possibility
+per CONTEXT line 101 / Open Question Q3 (RESOLVED). A future phase may revive
+or repurpose them.
+
+## Manual smoke (V-08 / V-09 / V-10 / V-11)
+
+Manual iOS-simulator smoke deferred — no simulator in this autonomous run.
+Static checks performed:
+- `./gradlew :composeApp:compileKotlinIosSimulatorArm64 -q` → exits 0
+- `./gradlew :composeApp:compileDebugKotlinAndroid -q` → exits 0
+- `./gradlew :composeApp:iosSimulatorArm64Test --tests "...AppShellGateTest"` → tests pass
+- `grep -r '@Ignore' composeApp/src/commonTest/` → 0 results
+
+`./gradlew :composeApp:check` is RED only because of pre-existing spotless
+violations in 38 unrelated files (predates this plan; confirmed via stash).

+# Phase 2.1: App Shell, Navigation & Search Foundation - Context
+
+**Gathered:** 2026-05-08
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Replace the post-login placeholder with the real app shell before household and domain data lands. Deliver four persistent top-level destinations (Planer, Przepisy, Spiżarnia, Zakupy) with independent per-tab back-stack boundaries, a Liquid-glass floating pill dock as the primary chrome, deliberate anticipatory empty states for every tab, and a functional search affordance (open/close + query echo only this phase) on Przepisy and Spiżarnia. Also introduce the first shared visual foundation built on Composables / Compose Unstyled + Liquid instead of expanding around Material 3 — including a full theme token scaffold (colors, typography, spacing, glass-surface) and a layered Liquid → Haze → flat fallback chain.
+
+**Out of scope for this phase** (carried by later phases):
+- Real search results or catalog data (Phase 5)
+- Household onboarding / membership (Phase 3)
+- SyncEngine wiring (Phase 4)
+- Per-screen feature content beyond empty states (Phases 5–9)
+- Real-device Liquid tuning + cross-screen polish (Phase 10)
+- Full Polish copy pass and i18n delivery (Phase 11) — but all strings introduced in this phase MUST go through resource lookup, not hardcoded literals
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Tab bar shape & chrome placement
+- **D-01:** Bottom-anchored floating pill dock implemented as a Liquid-glass capsule, centered above the safe-area inset. No edge-to-edge bottom bar.
+- **D-02:** All four tabs render icon + label at all times (active and inactive). Active tab is wider and visually emphasized; inactive tabs remain readable, not icon-only.
+- **D-03:** Tab order — `Planer` / `Przepisy` / `Spiżarnia` / `Zakupy`. Default landing tab on first sign-in is `Planer` (matches the "my week is planned" core value; departs from the literal UI-03 listing order, which research confirmed is non-binding).
+- **D-04:** No top app bar in v1. Tab title (where useful) lives inline at the top of each screen body. All chrome is bottom-anchored — one surface to design well.
+- **D-05:** When search is opened (on tabs that have search — see D-06), the dock collapses to a single circular button showing only the active tab's icon (no label, slightly reduced height). Tapping that collapsed button closes the search and re-expands the dock. The transition is a single coordinated animation, not two independent ones. This matches the Apple-app pattern the user explicitly endorsed.
+
+### Search affordance behavior
+- **D-06:** Search button is per-tab and only present on `Przepisy` and `Spiżarnia` (the two tabs that will have searchable content in v1). `Planer` and `Zakupy` have no search button and no search surface. The button renders as a separate floating circular icon adjacent to the dock (not inside it), matching the mockup.
+- **D-07:** This phase delivers open/close, query input echo, and clear/close actions only. The body of the search surface renders nothing (no placeholder list, no empty-state body) — Phase 5 wires real result rendering for Przepisy, and the corresponding pantry phase wires Spiżarnia. UI-10 is satisfied by demonstrating the affordance is functional, not by faking content.
+- **D-08:** Closing the search clears the query. Reopening starts blank. No persistence across close, tab-switch, or app launch.
+- **D-09:** Search is an inline bottom pill, not a full-screen sheet. The search input expands across the bottom chrome row alongside the collapsed dock toggle (D-05). Body content stays visible behind it.
+
+### Empty state design language
+- **D-10:** Visual treatment is icon + headline + subline. Icon is tab-themed (calendar for Planer, book for Przepisy, warehouse for Spiżarnia, cart for Zakupy), rendered in a calm, low-saturation theme color. No bespoke illustrations in this phase.
+- **D-11:** Tone is anticipatory in Polish — copy signals the feature is real but waiting (e.g. "Wkrótce zobaczysz tu swój plan tygodnia"). Avoid neutral "Brak danych" and avoid chatty onboarding copy.
+- **D-12:** No CTA buttons in empty states this phase. Households and catalog don't exist yet, so any CTA would either no-op or navigate to another empty screen. CTAs are added in feature phases as actions become real.
+- **D-13:** Single reusable `EmptyState(icon, title, subtitle, action?)` composable in `ui/components/`. The `action` slot is optional and unused this phase but reserved so feature phases can add CTAs without a new component.
+
+### Theme tokens + Liquid fallback
+- **D-14:** Full theme scaffold this phase — semantic color roles (background, surface, surfaceGlass, content, contentMuted, accent, separator, borderCard), a typography scale with named text styles (display/title/body/caption), a spacing scale (4/8/12/16/24/32), and a `GlassSurface` token primitive consumed by the dock, search pill, and search/filter buttons. Phase 5 inherits cleanly; Phase 10 tunes on real hardware.
+- **D-15:** Both light and dark color schemes are defined and follow the system setting. UI-05 fully lands in Phase 5 but the foundation must be correct now so Phase 5 doesn't retrofit. The mockup's CSS palette (`--app-bg-rgb`, `--card-rgb`, `--sunken-rgb`, etc.) is a useful reference but is NOT directly ported — the visual rebuild owns its own palette.
+- **D-16:** `GlassSurface` is a layered primitive with a Liquid → Haze → flat translucent fallback chain. All three paths consume the same token API (color + opacity + radius). Liquid is the preferred path for chrome/buttons; Haze is the secondary blur path; the flat path is a solid translucent surface using theme tokens for the worst case.
+- **D-17:** Fallback engagement is compile-time per-target plus a runtime debug toggle. Compile-time: if Liquid does not compile or ship for a given target, the build picks the fallback at build time (no runtime guards in production binaries). Runtime: a debug-build-only toggle (via `multiplatform-settings`, surfaced through a hidden settings entry or build flag) lets the user switch GlassSurface between Liquid / Haze / flat to compare on-device. No automatic perf detection in v1 — Phase 10 may revisit.
+
+### Claude's Discretion
+- Exact Liquid library API usage and effect parameters (radius, blur amount, refraction strength) — to be researched against the Liquid library's current docs by gsd-phase-researcher
+- Nav graph topology: single root NavHost vs nested NavHosts per tab. Recommendation in research SUMMARY.md is nested per tab for independent back stacks; planner should default to that unless research surfaces a CMP-specific blocker
+- Whether to migrate the Phase 2 Material 3 auth screens to the new component foundation now or leave them as legacy until a later phase. Default: leave auth screens as-is; do not expand Material 3 into new code
+- Specific empty-state copy strings (subject to Phase 11 copy pass; placeholders this phase must still go through resource lookup)
+- Icon source — Compose Material Icons vs a calmer custom icon set. Default to Material Icons Outlined for v1 unless research surfaces a clearly better option that fits the Liquid aesthetic
+- Animation curves and durations for the search-open dock collapse (D-05) — should feel iOS-native; planner can pick a reasonable default and Phase 10 tunes
+- Accessibility specifics: tab bar `Role.Tab` semantics, search button label, focus order between collapsed dock and search input — pick reasonable defaults aligned with iOS VoiceOver expectations
+- Whether to expose the runtime fallback toggle (D-17) as an in-app debug-build affordance or as a build flag only

+<code_context>
+## Existing Code Insights
+
+### Reusable Assets
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/App.kt` — Current root composable; will host the new shell after auth gate. Currently routes to `LoginScreen` / `PostLoginPlaceholderScreen` based on `AuthSession` state.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/theme/RecipeTheme.kt` — Theme entry point exists but is minimal. This phase expands it into the full token scaffold (D-14, D-15).
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/di/AppModule.kt` — Koin app module; new screen ViewModels register here (or in a new `ui/UiModule.kt`).
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/screens/auth/PostLoginPlaceholderScreen.kt` — The placeholder this phase replaces. Should be retired (or reduced to a degenerate "Authenticating…" sliver) once the shell exists; `PostLoginViewModel.kt` may continue to drive the bridge.
+- `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/auth/AuthSession.kt` — State machine the shell observes to decide whether to render auth flow or shell. No changes expected here; the shell sits downstream.
+
+### Established Patterns
+- ViewModel + StateFlow + method-per-action — every Phase 2 screen follows this; new shell screens MUST follow it (`PlannerViewModel`, `RecipesViewModel`, `PantryViewModel`, `ShoppingViewModel`, plus a `SearchViewModel` per searchable tab).
+- Koin module-per-feature — `AuthModule.kt`, `UserModule.kt`. New shell adds `NavigationModule.kt` (or folds into `AppModule.kt`) and one ViewModel module per tab area.
+- Strings externalized via Compose Resources — Phase 2 already established this; new shell must NOT introduce hardcoded literals (UI-01 / convention #9).
+- Material 3 used in auth screens only — do NOT extend Material 3 into shell code; build new components on Compose Unstyled (PROJECT.md decision).
+- iOS Kotlin/Native binary flags already set (`objcDisposeOnMain=false`, `gc=cms`) per Phase 1.
+
+### Integration Points
+- Auth gate: shell renders only when `AuthSession.state == Authenticated`. The shell becomes the new "authenticated root" — replacing `PostLoginPlaceholderScreen` as the destination of the auth gate transition in `App.kt`.
+- Navigation: introduces `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/navigation/` package — root NavHost + per-tab nested NavHosts + serializable route definitions. Phase 3 (households) will hook onboarding into this graph; Phase 5 (catalog) will populate the Recipes nested graph.
+- Theme tokens: every later phase reads these. Get the API right now — colors as semantic roles, not raw hex; typography as named styles, not raw `TextStyle`; spacing as named ints, not magic numbers.
+- Search ViewModel surface: this phase delivers the open/close/query state machine for Recipes + Pantry search. Phase 5 plugs results in by injecting a search-results-source dependency into the same ViewModel — design the API for that injection point now.
+- GlassSurface primitive: lives in `ui/components/` (or `ui/theme/glass/`). The dock, search pill, and floating action buttons all consume it. Future polish chrome (Phase 10) tunes here without touching call sites.
+
+</code_context>
+
+<specifics>
+## Specific Ideas
+
+- "When search bar is shown then from the menu only active button is visible and without label but then the whole is a little bit smaller in height" — verbatim user intent for the dock-collapse-on-search transition (D-05). The transition is a single coordinated motion, not two independent ones.
+- "I've seen it in some Apple apps and I like it" — re: dock collapsing into a single button when search opens. Reference point is iOS native apps (Mail, Notes, Settings) where the bottom chrome morphs as the search context activates. The Liquid library's pixel-sampling capabilities are the right tool to make this feel native rather than mechanical.
+- "All tabs show labels" — explicit departure from a typical iOS tab bar where inactive labels can be hidden. The user wants every tab readable at all times; the active tab differentiates by width and emphasis, not by being the only labeled one.
+- The mockup's `app-bottom-nav` is the structural reference — a floating capsule with adjacent floating circular action buttons, not a flat edge-to-edge nav bar. Visual styling is being rebuilt; the floating-pill geometry and the "search open collapses the dock" state machine are what's being preserved.
+
+</specifics>
+
+<deferred>
+## Deferred Ideas
+
+- Per-tab dock collapse to a single button on certain tabs/scroll states (independent of search) — mockup has this for some views; defer to Phase 10 if real-device feel demands it. Not in scope here; this phase only collapses the dock for the search-open transition.
+- Profile / settings entry point in chrome — no top bar this phase (D-04) means there's no obvious slot. Households/profile UI lands in Phase 3; revisit chrome placement then.
+- Cross-tab CTAs in empty states (e.g. "Browse recipes" on empty Planer) — deferred until target tabs have content (Phase 5+).
+- Custom illustrations for empty states — deferred; icon-based v1 (D-10).
+- Material 3 migration of Phase 2 auth screens — leave as legacy; revisit when Phase 10 polishes chrome or when a phase touches login flow visually.
+- Runtime perf detection that auto-downgrades GlassSurface — deferred to Phase 10. Compile-time + debug toggle is enough for v1 (D-17).
+- Persisting search query across sessions — explicitly rejected (D-08). Per-tab session-level persistence is also out of scope.
+- Real-device Liquid tuning (refraction strength, specular highlights, animation curves) — that's Phase 10's job; this phase ships a working approximation with sensible defaults.
+- Localization (full Polish copy pass) — Phase 11. Strings introduced this phase go through resource lookup but the catalog of copy is not finalized.

+
+> **Audit trail only.** Do not use as input to planning, research, or execution agents.
+> Decisions are captured in CONTEXT.md — this log preserves the alternatives considered.
+
+**Date:** 2026-05-08
+**Phase:** 02.1-app-shell-navigation-search-foundation
+**Areas discussed:** Tab bar shape & chrome placement, Search affordance behavior, Empty state design language, Theme tokens + Liquid fallback
+
+---
+
+## Tab bar shape & chrome placement
+
+### Q1 — Adopt the mockup's floating pill dock for the tab bar?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Floating pill dock (Recommended) | Centered, bottom-anchored Liquid-glass capsule. Active wider with icon+label, inactive icon-only circles. | ✓ (with modification) |
+| Static bottom tab bar (full-width) | Edge-to-edge fixed-width tabs. | |
+| Platform-adaptive | iOS pill, Android Material 3 NavigationBar. | |
+
+**User's choice:** Floating pill dock — but with labels on inactive tabs too (not just active). When search opens, the dock collapses to a single button showing only the active tab's icon (no label, slightly reduced height).
+**Notes:** User explicitly preferred a single visual language across platforms and wanted all tabs to remain readable; differentiation is by width/emphasis, not by hiding labels.
+
+### Q2 — Tab order and default landing tab?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Mockup order: Planer / Przepisy / Spiżarnia / Zakupy (Recommended) | Lands on Planer (hero feature). | ✓ |
+| REQ order: Przepisy / Planer / Spiżarnia / Zakupy | Follows UI-03 listing literally. | |
+| Last-used tab persisted | Remember across launches. | |
+
+**User's choice:** Mockup order; lands on Planer.
+**Notes:** Aligns with the "my week is planned" core value.
+
+### Q3 — Top app bar in v1?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| No top bar — bottom chrome only (Recommended) | Mirror mockup; one chrome surface. | ✓ |
+| Minimal top bar with title | Plain text title per tab. | |
+| Top bar with title + profile/settings icon | Adds global affordance. | |
+
+**User's choice:** No top bar.
+**Notes:** Simpler chrome story; profile/settings will find its slot when Phase 3 lands.
+
+### Q4 — Mockup's collapsible-dock behavior in this phase?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Defer collapse-to-toggle (Recommended) | Static pill; revisit in Phase 10. | |
+| Implement collapse-to-toggle now | Match mockup fully. | ✓ (scoped to search-open) |
+| You decide | Claude's discretion. | |
+
+**User's choice:** Implement the collapse, but only as the transition that happens when search opens (not the per-tab/scroll-state collapse). Inspired by Apple apps where bottom chrome morphs as search context activates.
+**Notes:** Per-tab/scroll collapse is deferred to Phase 10; only search-open collapse is in scope here.
+
+---
+
+## Search affordance behavior
+
+### Q1 — Where does the search button live?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Per-tab on Przepisy + Spiżarnia (Recommended) | Floating circular button next to dock; only on tabs with searchable content. | ✓ |
+| Global on every tab | Always present; ambiguous on Planer/Zakupy. | |
+| Per-tab on all four tabs | Tab-scoped behavior including tabs with no v1 search. | |
+
+**User's choice:** Per-tab on Przepisy + Spiżarnia only.
+**Notes:** Matches mockup; avoids designing search states for tabs with no v1 content.
+
+### Q2 — Search surface behavior before real data exists (this phase)?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Functional input + empty-state placeholder body (Recommended) | Open/close + query, body shows "Brak danych do przeszukania". | |
+| Functional input + dimmed/disabled visual | Greyed body. | |
+| Just open/close + query echo | No body content rendered. | ✓ |
+
+**User's choice:** Open/close + query echo only.
+**Notes:** Lightest scaffolding; Phase 5 will wire result rendering. UI-10 is satisfied by demonstrating the affordance is functional, not by faking content.
+
+### Q3 — Search query state — what persists?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Cleared on close (Recommended) | iOS-typical behavior. | ✓ |
+| Persists per-tab within session | Foreground only. | |
+| Persists per-tab across launches | Saved via multiplatform-settings. | |
+
+**User's choice:** Cleared on close.
+**Notes:** Simplest mental model; aligns with iOS conventions.
+
+### Q4 — Search input — inline pill or full-screen sheet?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Inline bottom pill, dock collapses next to it (Recommended) | Mockup behavior. | ✓ |
+| Full-screen modal sheet | iOS Settings/Mail style. | |
+| Inline with results overlay | Pill + translucent overlay. | |
+
+**User's choice:** Inline bottom pill.
+**Notes:** Coordinated with the dock-collapse transition (Tab Q4).
+
+---
+
+## Empty state design language
+
+### Q1 — Empty state visual treatment?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Icon + headline + subline (Recommended) | Tab-themed icon, calm color, no bespoke art. | ✓ |
+| Custom illustrations per tab | Bespoke SVG/PNG per state. | |
+| Text-only, no icon | Centered headline + subline only. | |
+
+**User's choice:** Icon + headline + subline.
+**Notes:** No illustration assets needed; cheap and on-brand.
+
+### Q2 — Empty state tone?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Anticipatory — "soon you'll see X" (Recommended) | Forward-looking Polish copy. | ✓ |
+| Neutral / informational | "Brak danych" style. | |
+| Welcoming with onboarding hint | Chatty onboarding copy. | |
+
+**User's choice:** Anticipatory.
+**Notes:** Honestly signals the feature is real but waiting.
+
+### Q3 — CTA buttons in empty states this phase?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| No CTAs in this phase (Recommended) | Add as actions become real. | ✓ |
+| Disabled-looking CTA placeholders | Greyed, inert. | |
+| Cross-tab CTAs | "Browse recipes" → Przepisy (also empty). | |
+
+**User's choice:** No CTAs.
+**Notes:** Households (Phase 3) and catalog (Phase 5) don't exist yet; CTAs would no-op.
+
+### Q4 — Empty state component architecture?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Single reusable EmptyState composable (Recommended) | `EmptyState(icon, title, subtitle, action?)`. | ✓ |
+| Per-screen bespoke composables | Each screen rolls its own. | |
+| You decide | Claude's discretion. | |
+
+**User's choice:** Single reusable EmptyState composable with optional action slot.
+**Notes:** Action slot reserved unused this phase; feature phases populate it.
+
+---
+
+## Theme tokens + Liquid fallback
+
+### Q1 — Theme token scaffolding scope for this phase?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Full scaffold: colors + typography + spacing + glass-surface (Recommended) | Phase 5 inherits cleanly; Phase 10 tunes. | ✓ |
+| Minimal: only what the shell uses | Defer typography/spacing to feature phases. | |
+| Full scaffold + lift mockup CSS palette directly | Seed palette from `--*-rgb` vars. | |
+
+**User's choice:** Full scaffold; mockup palette is reference, not directly ported.
+**Notes:** The visual rebuild owns its own palette.
+
+### Q2 — Light/dark scheme posture?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Both schemes defined; system-following (Recommended) | UI-05 foundation here, full landing in Phase 5. | ✓ |
+| Light-only this phase, dark in Phase 5 | Half-build now. | |
+| Both, but app forces dark | Light tokens un-tested. | |
+
+**User's choice:** Both, system-following.
+**Notes:** Avoids retrofit cost in Phase 5.
+
+### Q3 — Liquid fallback strategy?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Liquid → Haze → flat fallback chain (Recommended) | Layered primitive, same token API. | ✓ |
+| Liquid + flat fallback (skip Haze) | Two-tier, no middle quality. | |
+| Liquid-only, no fallback | Cheapest now. | |
+
+**User's choice:** Three-tier layered fallback.
+**Notes:** `GlassSurface` primitive consumes the same token API across all three paths.
+
+### Q4 — When does fallback engage?
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Compile-time per-target + runtime debug toggle (Recommended) | Build-time selection; debug-build comparison toggle. | ✓ |
+| Always-best, no toggle | Silent platform selection. | |
+| Runtime perf detection auto-downgrades | Real engineering investment. | |
+
+**User's choice:** Compile-time + debug toggle.
+**Notes:** No automatic perf detection in v1; Phase 10 may add it.
+
+---
+
+## Claude's Discretion
+
+- Liquid library API specifics (radius, blur, refraction values) — researcher to surface
+- Nav graph topology — default to nested NavHost per tab unless research blocks it
+- Whether to migrate Phase 2 Material 3 auth screens now — default: leave as legacy
+- Specific empty-state copy strings (subject to Phase 11 copy pass)
+- Icon source — Material Icons Outlined unless research surfaces a better fit
+- Animation curves and durations for the dock-collapse-on-search transition
+- Accessibility specifics (Role.Tab semantics, focus order)
+- Whether to expose the GlassSurface debug toggle in-app or as a build flag
+
+## Deferred Ideas
+
+- Per-tab/scroll-state dock collapse (mockup) — Phase 10
+- Profile/settings entry point in chrome — Phase 3 onboards households first
+- Cross-tab CTAs in empty states — feature phases as content lands
+- Custom empty-state illustrations
+- Material 3 migration of auth screens
+- Runtime perf detection auto-downgrade for GlassSurface — Phase 10
+- Persisting search query across sessions / tab-switches
+- Real-device Liquid tuning — Phase 10

+
+## Pattern Assignments
+
+### `App.kt` (modified — auth gate router)
+
+**Analog:** self — current `App.kt:43-58` has the `when (authState)` switch and the `Authenticated + currentUser` two-layer gate.
+
+**Pattern to preserve** (`App.kt:43-58`):
+```kotlin
+when (authState) {
+    AuthState.Loading -> SplashScreen()
+
+    AuthState.Unauthenticated -> LoginScreen(viewModel = koinViewModel<LoginViewModel>())
+
+    AuthState.Authenticated -> {
+        val user = currentUser
+        if (user == null) {
+            SplashScreen()
+        } else {
+            PostLoginPlaceholderScreen(
+                user = user,
+                viewModel = koinViewModel<PostLoginViewModel>(),
+            )
+        }
+    }
+}
+```
+
+**Modification:** replace the `PostLoginPlaceholderScreen(...)` call with `AppShell()` (which internally hosts `RootNavHost` and consumes its own `koinViewModel<ShellViewModel>()`). The `currentUser == null → SplashScreen()` arm stays. Do NOT change the `LaunchedEffect(authSession) { initialize() }` block (`App.kt:39-41`) — still load-bearing. Do NOT delete `PostLoginPlaceholderScreen` / `PostLoginViewModel` yet — RESEARCH.md § Open Question 3 + CONTEXT line 101 keep them as a logout-bridge possibility; if unused after wiring, retire them in a separate task with explicit confirmation.
+
+---
+
+### `RecipeTheme.kt` (rewritten — theme entry + CompositionLocal scaffold)
+
+**Analog:** self — current shape (lines 18-35) is the structural template; the body is rewritten.
+
+**Pattern to extend** (current `RecipeTheme.kt:18-35`):
+```kotlin
+private val LightColors = lightColorScheme(primary = Color(0xFF3B6939))
+private val DarkColors = darkColorScheme(primary = Color(0xFFA2D597))
+
+@Composable
+fun RecipeTheme(content: @Composable () -> Unit) {
+    val colors = if (isSystemInDarkTheme()) DarkColors else LightColors
+    MaterialTheme(colorScheme = colors, content = content)
+}
+```
+
+**New shape** (RESEARCH.md § Pattern 3 + UI-SPEC § Color/Typography/Spacing/Glass):
+- Keep `MaterialTheme(colorScheme = ..., content = ...)` wrapping the inner block so legacy auth screens (`LoginScreen.kt:46`, `LoginScreen.kt:59` — `MaterialTheme.colorScheme.surface`, `MaterialTheme.typography.displaySmall`) keep resolving (Open Question 3, recommended resolution).
+- Inside the `MaterialTheme { ... }`, wrap a `CompositionLocalProvider(LocalRecipeColors provides ..., LocalRecipeTypography provides ..., LocalRecipeSpacing provides ..., LocalRecipeShapes provides ..., LocalRecipeGlass provides ..., LocalGlassBackend provides ...) { content() }`.
+- Public read site: `RecipeTheme.colors`, `RecipeTheme.typography`, `RecipeTheme.spacing`, `RecipeTheme.shapes`, `RecipeTheme.glass` — implement as a `companion object`-style `object RecipeTheme { val colors: RecipeColors @Composable @ReadOnlyComposable get() = LocalRecipeColors.current ... }` per the standard MaterialTheme idiom.
+
+**Color values:** UI-SPEC § Color (lines 84-92) — verbatim hex. No mockup port.
+
+---
+
+### `ui/screens/shell/ShellViewModel.kt` (new — VM analog: `LoginViewModel`)
+
+**Analog:** `ui/screens/auth/LoginViewModel.kt:37-55`
+
+**State + method-per-action pattern** (`LoginViewModel.kt:37-55`):
+```kotlin
+class LoginViewModel(
+    private val authSession: AuthSession,
+) : ViewModel() {
+    private val _state = MutableStateFlow(LoginScreenState())
+    val state: StateFlow<LoginScreenState> = _state.asStateFlow()
+
+    fun onSignInClick(browser: AuthBrowser): Job {
+        _state.value = LoginScreenState(isLoading = true, errorKey = null)
+        return viewModelScope.launch {
+            val result = authSession.login(browser)
+            _state.value = LoginScreenState(isLoading = false, errorKey = result.toErrorKeyOrNull())
+        }
+    }
+}
+```
+
+**Apply to `ShellViewModel`:**
+- `data class ShellState(val activeTab: BottomBarDestination, val searchOpen: Boolean = false, val query: String = "")` — single source of truth.
+- `private val _state = MutableStateFlow(ShellState(activeTab = BottomBarDestination.Planner))`; expose `state: StateFlow<ShellState> = _state.asStateFlow()`.
+- Method-per-action: `fun openSearch()`, `fun closeSearch()` (D-08: clears query), `fun onQueryChange(q: String)`, `fun clearQuery()`, `fun onTabChanged(dest: BottomBarDestination)`.
+- No `viewModelScope.launch` needed — pure synchronous state updates (no I/O this phase).
+
+**Same pattern for** `PlannerViewModel`, `RecipesViewModel`, `PantryViewModel`, `ShoppingViewModel`, `RecipesSearchViewModel`, `PantrySearchViewModel`. The two `*SearchViewModel`s use `data class SearchState(val isOpen: Boolean = false, val query: String = "")` per RESEARCH.md § Pattern 4 (lines 395-405). Phase 5 extension hook: leave a nullable `searchSource: SearchSource? = null` constructor param — RESEARCH.md line 410.
+
+---
+
+### `ui/screens/shell/AppShell.kt` (new — composable analog: `LoginScreen`)
+
+**Analog:** `ui/screens/auth/LoginScreen.kt:39-93` for the shape (Composable observing a VM + `collectAsStateWithLifecycle`); the actual layout follows RESEARCH.md § Code Example 2 (lines 514-565).
+
+**ViewModel observation pattern** (`LoginScreen.kt:39-42`):
+```kotlin
+@Composable
+fun LoginScreen(viewModel: LoginViewModel) {
+    val state by viewModel.state.collectAsStateWithLifecycle()
+    // ...
+}
+```
+
+**Apply to `AppShell`:**
+- Take no params (it lives behind the auth gate). Inside: `val vm: ShellViewModel = koinViewModel(); val ui by vm.state.collectAsStateWithLifecycle()`.
+- Acquire `navController = rememberNavController()`; render `RootNavHost(navController)` as the body.
+- Bottom chrome is an `Align(BottomCenter)` overlay column: `if (ui.searchOpen && activeTab.hasSearch) SearchPill(...); DockBar(active=activeTab, collapsed=ui.searchOpen, ...)`.
+- `FloatingSearchButton` aligned `BottomEnd`, visible only when `!ui.searchOpen && activeTab.hasSearch`.
+
+**Inset handling** (avoid Pitfall F, RESEARCH.md lines 471-473): `Modifier.windowInsetsPadding(WindowInsets.navigationBars)` on the chrome column; screen bodies use `WindowInsets.statusBars` for top inset only. Do NOT use `safeContentPadding()` on AppShell — that's `LoginScreen.kt:52`'s pattern, but only because `LoginScreen` has no chrome overlay. AppShell has chrome, so it must consume insets explicitly.
+
+---
+
+### `ui/screens/{planner,recipes,pantry,shopping}/{Tab}Screen.kt` (new — analog: `PostLoginPlaceholderScreen`)
+
+**Analog:** `ui/screens/auth/PostLoginPlaceholderScreen.kt:32-62`
+
+**Skeleton to mirror** (`PostLoginPlaceholderScreen.kt:38-61`):
+```kotlin
+Surface(
+    modifier = Modifier.fillMaxSize(),
+    color = MaterialTheme.colorScheme.surface,
+) {
+    Column(
+        modifier = Modifier
+            .fillMaxSize()
+            .safeContentPadding()
+            .padding(horizontal = 16.dp),
+        horizontalAlignment = Alignment.CenterHorizontally,
+        verticalArrangement = Arrangement.Center,
+    ) {
+        Text(
+            text = stringResource(Res.string.auth_welcome_format, user.displayName),
+            style = MaterialTheme.typography.headlineSmall,
+            textAlign = TextAlign.Center,
+        )
+        // ...
+    }
+}
+```
+
+**Adapt for tab screens:**
+- Replace `Surface(... color = MaterialTheme.colorScheme.surface)` with `Box(Modifier.fillMaxSize().background(RecipeTheme.colors.background))`. UI-SPEC line 184: tab body background is `RecipeColors.background`, NOT a Material `Surface`. Also, do NOT import `androidx.compose.material3.*` in new screen code (CLAUDE.md / UI-SPEC line 31 / RESEARCH.md anti-pattern at line 419).
+- Replace `MaterialTheme.typography.headlineSmall` with `RecipeTheme.typography.title` for the inline tab title (UI-SPEC line 64).
+- Replace hardcoded `padding(horizontal = 16.dp)` with `padding(horizontal = RecipeTheme.spacing.lg)` (UI-SPEC § Spacing).
+- The body region: inline title at top with `RecipeTheme.spacing.xl` top inset, then `EmptyState(icon = ..., title = stringResource(Res.string.empty_<tab>_title), subtitle = stringResource(Res.string.empty_<tab>_subtitle))` centered.
+- Each `*Screen(vm: *ViewModel)` takes its VM as a parameter so the composable is testable / previewable in isolation; the call site in `RootNavHost`'s `composable<*Home>` block does the `koinViewModel(viewModelStoreOwner = parentEntry)` retrieval (RESEARCH.md § Pattern 2, lines 351-357).
+
+---
+
+### `ui/components/empty/EmptyState.kt` (new — analog: `LoginScreen` column skeleton)
+
+**Analog:** `ui/screens/auth/LoginScreen.kt:48-92` for the centered Column pattern; full target shape locked by RESEARCH.md § Code Example 3 (lines 571-605) and UI-SPEC line 183.
+
+**Centered Column pattern from analog** (`LoginScreen.kt:48-56`):
+```kotlin
+Column(
+    modifier = Modifier
+        .fillMaxSize()
+        .safeContentPadding()
+        .padding(horizontal = 16.dp),
+    horizontalAlignment = Alignment.CenterHorizontally,
+    verticalArrangement = Arrangement.Center,
+) { /* ... */ }
+```
+
+**Apply to `EmptyState`:**
+- Signature locked by D-13 / UI-SPEC line 183: `EmptyState(icon: ImageVector, title: String, subtitle: String, modifier: Modifier = Modifier, action: (@Composable () -> Unit)? = null)`.
+- Replace `safeContentPadding()` with explicit horizontal `RecipeTheme.spacing.xl` (UI-SPEC line 183 sets the body inset and screen-level safe-area inset is owned by the screen, not the empty-state).
+- Tint: `Icon(... tint = RecipeTheme.colors.contentMuted, modifier = Modifier.size(48.dp))` — UI-SPEC line 183.
+- Spacing rhythm: icon → `Spacer(Modifier.height(RecipeTheme.spacing.sm))` → headline (`RecipeTheme.typography.display`, color `RecipeTheme.colors.content`) → `Spacer(... .lg)` → subline (`RecipeTheme.typography.body`, color `RecipeTheme.colors.contentMuted`) → if `action != null`, `Spacer(... .xl)` then `action()`.
+- Wrap the Column in `Modifier.semantics(mergeDescendants = true) {}` (UI-SPEC line 226; one-announce VoiceOver reading).

+
+### `di/ShellModule.kt` (new — analog: `auth/AuthModule.kt`)
+
+**Analog:** `auth/AuthModule.kt:9-25` and `user/UserModule.kt:10-23`.
+
+**Module + viewModel registration pattern** (`AuthModule.kt:9-25`):
+```kotlin
+val authModule =

+        single<SecureAuthStateStore> { SecureAuthStateStore(get()) }

+
+        viewModel<LoginViewModel>()
+        viewModel<PostLoginViewModel>()
+    }
+```
+
+**Apply to `shellModule`:**
+- `viewModel<ShellViewModel>()`, `viewModel<PlannerViewModel>()`, `viewModel<RecipesViewModel>()`, `viewModel<RecipesSearchViewModel>()`, `viewModel<PantryViewModel>()`, `viewModel<PantrySearchViewModel>()`, `viewModel<ShoppingViewModel>()`.
+- A `single<GlassBackend> { resolveGlassBackend(get<Settings>()) }` if the debug-toggle resolution is materialized at module level. Settings comes from `multiplatform-settings` (RESEARCH.md A5 — already wired from Phase 2).
+- Same imports: `import org.koin.dsl.module`, `import org.koin.plugin.module.dsl.viewModel`.

+### `di/AppModule.kt` (modified)
+
+**Analog:** self.
+
+**Pattern to extend** (`AppModule.kt:8-11`):
+```kotlin
+val appModule =
+    module {
+        includes(authModule, userModule)
+    }
+```
+
+**Modification:** add `shellModule` to the `includes(...)` list. One-line change. The comment on line 7 should be updated to reflect Phase 2.1 addition.
+
+---
+
+### `composeResources/values/strings.xml` (modified)
+
+**Analog:** self — current file has the `auth_*` keys.
+
+**Pattern to extend** (full current file shown above — `strings.xml:7-15`). Add the `shell_*`, `empty_*`, `search_*` resource keys per UI-SPEC § Copywriting Contract (lines 121-158) and RESEARCH.md § Code Example 4 (lines 615-637). Preserve all existing `auth_*` keys; only append.
+
+---
+
+### `ui/components/dock/DockBar.kt` (new — greenfield)
+
+**Analog:** none in repo. **Stylistic reference:** `LoginScreen.kt:62-80` (button structure with conditional content via `if (state.isLoading)`).
+
+**Key API contract** (locked by UI-SPEC line 180 + CONTEXT D-01 through D-05):
+- Signature: `DockBar(destinations: List<BottomBarDestination>, active: BottomBarDestination, collapsed: Boolean, onTabSelect: (BottomBarDestination) -> Unit, onCollapsedTap: () -> Unit, modifier: Modifier = Modifier)`.
+- Substrate: `GlassSurface(cornerRadius = 28.dp, ...)` for expanded; `GlassSurface(cornerRadius = 22.dp, ...)` for collapsed (UI-SPEC line 253).
+- Built on Compose Unstyled `TabGroup` primitive (UI-SPEC line 180; RESEARCH.md line 137 — `com.composables:composeunstyled:1.49.9`).
+- Animation: `Modifier.animateContentSize()` for expanded↔collapsed size + `AnimatedContent` for icon/label visibility crossfade. 250ms `FastOutSlowInEasing` per UI-SPEC line 198. Single coordinated motion (D-05).
+- Each cell: `Modifier.semantics { role = Role.Tab; selected = isActive }` (UI-SPEC line 220).
+- Touch target ≥ 44dp on iOS / 48dp on Android (UI-SPEC line 52, 224).
+
+---
+
+### `ui/components/dock/FloatingSearchButton.kt` (new — greenfield)
+
+**Analog:** none. UI-SPEC line 181.
+- Signature: `FloatingSearchButton(onClick: () -> Unit, modifier: Modifier = Modifier)`.
+- Built on Compose Unstyled `Button`, wrapping a `GlassSurface(cornerRadius = 22.dp)` (44dp full-circle).
+- Icon: `Icons.Outlined.Search`, tinted `RecipeTheme.colors.content`.
+- `contentDescription = stringResource(Res.string.search_open_a11y)`.
+
+---
+
+### `ui/components/search/SearchPill.kt` (new — greenfield)
+
+**Analog:** stylistic only — nothing equivalent in repo. UI-SPEC line 182.
+- Signature: `SearchPill(query: String, onQueryChange: (String) -> Unit, onClear: () -> Unit, onClose: () -> Unit, placeholder: String, modifier: Modifier = Modifier)`.
+- Built on Compose Unstyled `TextField` renderless primitive — apply local styling, do NOT roll a Material `OutlinedTextField`.
+- 44dp height, 22dp corner radius, `surfaceGlass` substrate (UI-SPEC line 253).
+- Leading search icon, trailing clear button visible only when `query.isNotEmpty()`.
+- `imePadding()` so the pill rides above the soft keyboard (UI-SPEC line 271; Pitfall F).
+
+---
+
+### `ui/components/glass/GlassSurface.kt` + backends (new — all greenfield)
+
+**Analog:** none. RESEARCH.md § Pattern 3 (lines 367-388) is the API lock.
+
+```kotlin
+@Composable
+fun GlassSurface(
+    modifier: Modifier = Modifier,
+    tint: Color = RecipeTheme.colors.surfaceGlass,
+    cornerRadius: Dp = 28.dp,
+    border: BorderStroke? = BorderStroke(1.dp, RecipeTheme.colors.borderCard),
+    content: @Composable BoxScope.() -> Unit,
+)
+```
+
+- Backend selected via `LocalGlassBackend.current` (CompositionLocal set once at `RecipeTheme`/`AppShell` startup).
+- Compile-time per target via `expect/actual` of an `expect val defaultGlassBackend: GlassBackend` in `commonMain` with `actual`s in `iosMain` (Liquid) and `androidMain` (Liquid). If targets emerge where Liquid does not compile, the `actual` returns `Haze`.
+- Debug runtime override: `multiplatform-settings` key `"debug.glass_backend"` checked at `RecipeTheme` init, in DEBUG builds only (gate via an `expect val isDebugBuild: Boolean`). Production binaries compile out the override path.
+- Liquid path uses `rememberLiquidState()` + `Modifier.liquefiable(state)` on the screen-body backdrop (set at `AppShell` level — Pitfall C, RESEARCH.md lines 454-458) and `Modifier.liquid(state)` on the chrome (`DockBar`, `SearchPill`, `FloatingSearchButton` interiors).
+
+---
+
+### `navigation/Routes.kt`, `BottomBarDestination.kt`, `RootNavHost.kt` (new — all greenfield)
+
+**Analog:** none. RESEARCH.md § Pattern 1 (lines 304-339) and § Code Example 1 (lines 487-510) lock the shape verbatim.
+
+Key contracts:
+- `@Serializable data object PlannerGraph; @Serializable data object PlannerHome; ...` — type-safe routing.
+- `enum class BottomBarDestination(val graphRoute: Any, val labelRes: StringResource, val icon: ImageVector, val hasSearch: Boolean, val searchPlaceholder: StringResource?)`. The `hasSearch` flag drives D-06 (search visibility per tab).
+- `NavHostController.navigateToTab(graphRoute: Any)` extension applies `popUpTo(graph.findStartDestination().id) { saveState = true }; launchSingleTop = true; restoreState = true`. This is the unit under test in `NavigationTest.kt`.
+- Per-tab VM scoping: in each `composable<*Home>` block, `val parent = remember(entry) { navController.getBackStackEntry(*Graph) }; val vm: *ViewModel = koinViewModel(viewModelStoreOwner = parent)` (RESEARCH.md § Pattern 2). Set this pattern now even with a single screen per graph — Phase 5 inherits cleanly.
+
+---
+
+### Test files (new)
+
+**Analog:** `commonTest/.../ui/screens/auth/LoginViewModelTest.kt:21-77` for VM tests; `commonTest/.../auth/AuthSessionTest.kt:11-29` for state-flow gate tests.
+
+**Pattern from `LoginViewModelTest.kt`** (lines 22-32):
+```kotlin
+class LoginViewModelTest {
+    @Test
+    fun cancelledAuthFailureMapsToCancelledStringResource() =
+        runTest {
+            val session = newSession(loginResult = OidcResult.Cancelled)
+            val viewModel = LoginViewModel(session)
+
+            viewModel.onSignInClick(NoopBrowser).join()
+
+            assertEquals(Res.string.auth_error_cancelled, viewModel.state.value.errorKey)
+            assertEquals(false, viewModel.state.value.isLoading)
+        }
+}
+```
+
+**Apply to `RecipesSearchViewModelTest` / `PantrySearchViewModelTest`:**
+- `runTest { ... }` block; no fakes needed (VMs are pure — no I/O).
+- Cover: open() → `isOpen=true`; onQueryChange("foo") → `query="foo"`; close() → `isOpen=false, query=""` (D-08); clear() → `query="", isOpen=true` (UI-SPEC line 206 + CONTEXT D-08).
+
+**Apply to `AppShellGateTest`** — mirror `AuthSessionTest.kt:13-23` shape (state-machine assertion via `runTest`). Drives `App()` indirectly by stubbing `AuthSession` + `UserRepository` via Koin test container, asserts `Authenticated + currentUser != null` resolves to AppShell rather than the placeholder. Plan to inject test doubles via Koin `startKoin { modules(...) }` per `Koin.kt:7-11` shape.
+
+**Apply to `NavigationTest`** — assert the `navigateToTab(...)` extension's `NavOptionsBuilder` lambda flips the four flags. If `TestNavHostController` is unavailable in CMP commonTest, assert by capturing a fake builder. Mark this as an investigation point in Wave 0.
+
+**Apply to `GlassBackendTest` / `GlassBackendOverrideTest`** — pure-function tests over the `resolveGlassBackend(settings: Settings, isDebug: Boolean, default: GlassBackend)` function. Use `MapSettings` (multiplatform-settings test impl) per RESEARCH.md line 731.
+
+---
+
+## Shared Patterns
+
+### Externalized strings (UI-01, CLAUDE.md #9)
+
+**Source:** `composeResources/values/strings.xml` + `recipe.composeapp.generated.resources.Res`.
+
+**Apply to:** every new screen, every new component that displays user-facing text. Zero hardcoded literals.
+
+**Reference call site** (`LoginScreen.kt:28-31, 58, 78`):
+```kotlin
+import org.jetbrains.compose.resources.stringResource
+import recipe.composeapp.generated.resources.Res
+import recipe.composeapp.generated.resources.auth_app_name
+// ...
+Text(text = stringResource(Res.string.auth_app_name), ...)
+```
+
+**ViewModel-side resource handles** — when a VM needs to surface a string to the screen but stay locale-agnostic, return a `StringResource` (not a `String`). See `LoginViewModel.kt:13, 24, 57-63`:
+```kotlin
+import org.jetbrains.compose.resources.StringResource
+// ...
+data class LoginScreenState(val isLoading: Boolean = false, val errorKey: StringResource? = null)
+```
+
+This phase: search VM state holds the raw `query: String` (it's user input, not a localized message). The `placeholder` for the search pill is resolved via the per-tab `searchPlaceholder: StringResource` on `BottomBarDestination`.
+
+### ViewModel + StateFlow + method-per-action (CLAUDE.md convention)
+
+**Source:** `LoginViewModel.kt:37-55`, `PostLoginViewModel.kt:15-23`.
+
+**Apply to:** `ShellViewModel`, `PlannerViewModel`, `RecipesViewModel`, `RecipesSearchViewModel`, `PantryViewModel`, `PantrySearchViewModel`, `ShoppingViewModel`.
+
+Universal shape:
+- `private val _state = MutableStateFlow(<TabState>())`
+- `val state: StateFlow<TabState> = _state.asStateFlow()`
+- Each action is a method on the VM that calls `_state.update { ... }` or `_state.value = ...`.
+- No `LiveData`, no `mutableStateOf` for primary state — `StateFlow` only.
+
+### Screen → VM observation
+
+**Source:** `App.kt:33-34`, `LoginScreen.kt:40`.
+
+**Pattern:**
+```kotlin
+import androidx.lifecycle.compose.collectAsStateWithLifecycle
+// ...
+val state by viewModel.state.collectAsStateWithLifecycle()
+```
+
+**Apply to:** every new screen and to `AppShell`. Use `collectAsStateWithLifecycle` not `collectAsState` so iOS/Android lifecycle-aware suspension works.
+
+### Koin VM injection at composition
+
+**Source:** `App.kt:46, 55`, `AuthModule.kt:23-24`.
+
+**Pattern:**
+- Module: `viewModel<*ViewModel>()`.
+- Call site: `val vm: *ViewModel = koinViewModel<*ViewModel>()` for non-tab-scoped, OR `val parent = remember(entry) { navController.getBackStackEntry(*Graph) }; val vm: *ViewModel = koinViewModel(viewModelStoreOwner = parent)` for tab-graph-scoped (RESEARCH.md § Pattern 2 — set the scoping pattern from day one).
+
+### iOS-safe inset handling
+
+**Apply to:** `AppShell` (chrome insets), every screen body (top inset).
+- Chrome bottom: `Modifier.windowInsetsPadding(WindowInsets.navigationBars)` (or `.union(WindowInsets.ime)` for the search pill).
+- Body top: respect `WindowInsets.statusBars` via padding.
+- Do NOT layer `safeContentPadding()` on both AppShell and screens — Pitfall F.
+
+### Material 3 boundary
+
+**Source:** UI-SPEC line 31; CLAUDE.md project decision; RESEARCH.md anti-pattern at line 419.
+
+**Apply to:** every new file outside `ui/screens/auth/`. **No `androidx.compose.material3.*` imports** in new code. Tab screens replace `Surface(... color = MaterialTheme.colorScheme.surface)` with `Box(Modifier.background(RecipeTheme.colors.background))`. Replace `MaterialTheme.typography.*` with `RecipeTheme.typography.*`. Use Compose Unstyled primitives where a renderless analog exists.
+
+The legacy auth screens (`LoginScreen.kt`, `PostLoginPlaceholderScreen.kt`, `SplashScreen.kt`) keep their Material 3 imports — explicit user discretion in CONTEXT line 52, default "leave auth screens as-is".
+
+### Glass on chrome only
+
+**Source:** CLAUDE.md non-negotiable #10; PITFALLS Pitfall 5/12.
+
+**Apply to:** `GlassSurface` is consumed by `DockBar`, `FloatingSearchButton`, `SearchPill` exclusively. Tab body / EmptyState / future list rows render flat. Lint discipline per Pitfall E — any direct Liquid/Haze API import outside `ui/components/glass/` is a bug.

+## User Constraints (from CONTEXT.md)
+
+### Locked Decisions
+
+**Tab bar shape & chrome placement**
+- **D-01:** Bottom-anchored floating pill dock implemented as a Liquid-glass capsule, centered above the safe-area inset. No edge-to-edge bottom bar.
+- **D-02:** All four tabs render icon + label at all times (active and inactive). Active tab is wider and visually emphasized; inactive tabs remain readable, not icon-only.
+- **D-03:** Tab order — `Planer` / `Przepisy` / `Spiżarnia` / `Zakupy`. Default landing tab on first sign-in is `Planer`.
+- **D-04:** No top app bar in v1. Tab title (where useful) lives inline at the top of each screen body. All chrome is bottom-anchored.
+- **D-05:** When search opens (on tabs that have search), the dock collapses to a single circular button showing only the active tab's icon (no label, slightly reduced height). Tapping it closes search and re-expands the dock. Single coordinated animation.
+
+**Search affordance behavior**
+- **D-06:** Search button per-tab, only on `Przepisy` and `Spiżarnia`. Floating circular icon adjacent to the dock (not inside it).
+- **D-07:** This phase delivers open/close + query input echo + clear/close actions only. Search-surface body renders nothing (Phase 5 wires real results for Recipes; Pantry phase wires Spiżarnia).
+- **D-08:** Closing the search clears the query. Reopening starts blank. No persistence across close, tab-switch, or app launch.
+- **D-09:** Search is an inline bottom pill, not a full-screen sheet. Body content stays visible behind it.
+
+**Empty state design language**
+- **D-10:** Icon + headline + subline. Icon is tab-themed, low-saturation theme color. No bespoke illustrations.
+- **D-11:** Anticipatory Polish tone (e.g. "Wkrótce zobaczysz tu swój plan tygodnia"). No "Brak danych", no chatty onboarding.
+- **D-12:** No CTA buttons in empty states this phase.
+- **D-13:** Single reusable `EmptyState(icon, title, subtitle, action?)` composable in `ui/components/`; `action` slot reserved unused this phase.
+
+**Theme tokens + Liquid fallback**
+- **D-14:** Full theme scaffold this phase — semantic colors (background, surface, surfaceGlass, content, contentMuted, accent, separator, borderCard), typography scale (display/title/body/label, two weights), spacing scale (`xs`/`sm`/`lg`/`xl`/`2xl`/`3xl` per UI-SPEC revision 1), `GlassSurface` token primitive consumed by dock + search pill + floating buttons.
+- **D-15:** Both light and dark color schemes defined; system-following.
+- **D-16:** `GlassSurface` is layered Liquid → Haze → flat translucent fallback chain. All three paths consume same token API (color + opacity + radius).
+- **D-17:** Compile-time per-target backend selection + debug-build runtime toggle (via `multiplatform-settings`). No automatic perf detection in v1.
+
+### Claude's Discretion
+- Exact Liquid library API parameters (radius, blur amount, refraction)
+- Nav graph topology (default: nested NavHosts per tab unless research blocks it — research below confirms this is correct)
+- Whether to migrate Phase 2 Material 3 auth screens (default: leave as legacy)
+- Specific empty-state copy strings (Phase 11 will tune; UI-SPEC has best-current values)
+- Icon source (default: Material Icons Outlined)
+- Animation curves and durations for search-open dock collapse (UI-SPEC suggests 250ms `FastOutSlowInEasing`)
+- Accessibility specifics (Role.Tab, focus order)
+- Whether to expose runtime fallback toggle as in-app debug affordance or build flag
+
+### Deferred Ideas (OUT OF SCOPE)
+- Per-tab/scroll-state dock collapse independent of search → Phase 10
+- Profile/settings entry point in chrome → Phase 3+
+- Cross-tab CTAs in empty states → feature phases
+- Custom illustrations for empty states
+- Material 3 migration of Phase 2 auth screens
+- Runtime perf auto-downgrade for GlassSurface → Phase 10
+- Persisting search query across sessions
+- Real-device Liquid tuning (refraction, specular) → Phase 10
+- Localization (full Polish copy pass) → Phase 11

+- Navigation: `org.jetbrains.androidx.navigation:navigation-compose` (JetBrains-official CMP port). No alternative.
+- ViewModel + StateFlow, method-per-action.
+- DI: Koin (`koin-core`, `koin-compose`, `koin-compose-viewmodel`). `koinViewModel()` everywhere.

+
+## Summary
+
+Phase 2.1 replaces the post-login placeholder with the real four-tab app shell. Three load-bearing pieces:
+
+1. **Navigation:** Single root `NavHost` containing four `navigation(...)` sub-graphs (one per tab) using `org.jetbrains.androidx.navigation:navigation-compose` 2.9.x (CMP port). Bottom-tab reselection uses `popUpTo(graph.findStartDestination().id) { saveState = true }; launchSingleTop = true; restoreState = true` so each tab's back stack survives switching. Routes are `@Serializable` `data object` / `data class` per JetBrains type-safe routing. ViewModels per tab area are scoped to the parent nav-graph `NavBackStackEntry` via `koinViewModel(viewModelStoreOwner = parentEntry)`.
+
+2. **Component foundation:** `compose-unstyled` (`com.composables:composeunstyled:1.49.x`) provides renderless primitives for `TabGroup`, `Button`, `TextField`, `Modal`/`BottomSheet`. Recipe-styled components in `ui/components/` consume those primitives and apply `RecipeTheme` tokens. Material 3 imports are confined to `ui/screens/auth/*` (legacy).
+
+3. **Glass surface:** `GlassSurface` primitive in `ui/components/glass/` with three backends — Liquid (`io.github.fletchmckee.liquid:liquid:1.1.1`, modifier `liquid(state)` + `liquefiable(state)`), Haze (`dev.chrisbanes.haze:haze:1.x`), and flat translucent. Backend selection is compile-time per-target (Gradle source-set wiring) plus a debug-build runtime override stored in `multiplatform-settings`. Liquid is preferred on iOS+Android; Haze is the secondary blur path; flat is last resort.
+
+**Primary recommendation:** Build top-down — root `AppShell` composable hosting one CMP `NavHost` with four `navigation()` sub-graphs, bottom dock + floating search button as overlay, per-tab `koinViewModel()` scoped to parent graph entry, all glass effects funneled through `GlassSurface`. Strings always via `stringResource(Res.string.*)` against `composeResources/values/strings.xml`. No `androidx.compose.material3.*` imports outside `ui/screens/auth/`.
+
+---
+
+## Architectural Responsibility Map
+
+| Capability | Primary Tier | Secondary Tier | Rationale |
+|------------|-------------|----------------|-----------|
+| Tab navigation + back stacks | KMP client (Compose UI) | — | Pure client UX; no server interaction |
+| Search affordance state | KMP client (per-tab ViewModel) | — | Local UI state; no persistence (D-08) |
+| Theme tokens / `RecipeTheme` | KMP client (ui/theme) | — | Renders identically across platforms |
+| Liquid/Haze/flat backend selection | KMP client (compile-time per Kotlin source set) | Runtime debug toggle | Per-platform shader capability |
+| Empty-state copy | KMP resources (`composeResources/values/strings.xml`) | Phase 11 localization | Resource-keyed; copy may tune later |
+| Auth gate (still upstream of shell) | KMP client (App.kt observes `AuthSession`) | — | Unchanged from Phase 2; shell sits downstream |
+
+No server changes in this phase. No `shared/commonMain` changes (UI is client-only).

+## Standard Stack
+
+### Core (already in `gradle/libs.versions.toml` or to add)
+
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| `org.jetbrains.androidx.navigation:navigation-compose` | **2.9.2** (latest as of 2026-05-08) — currently NOT in catalog; **add** | CMP-official navigation; type-safe routes; multi-back-stack support | JetBrains-official port of Jetpack Navigation; locked in CLAUDE.md |
+| `androidx-lifecycle-viewmodelCompose` | 2.10.0 (already in catalog) | `ViewModel` + `viewModelScope` in commonMain | Already locked Phase 2 |
+| `koin-compose` / `koin-composeViewmodel` | 4.2.1 (already in catalog) | `koinViewModel()`, `koinInject()` | Already locked |
+| `compose-components-resources` | 1.10.3 (already in catalog) | `Res.string.*`, `stringResource()` | CMP standard for strings |
+| `androidx-compose-material-icons-extended` | n/a — needs investigation; CMP equivalent is via `compose-material-icons-core` or use `material3` icons (already pulled by Phase 2 auth scaffold) | Outlined icon set for tabs + empty states | UI-SPEC selected `Icons.Outlined.*` | [VERIFIED: UI-SPEC + libs.versions.toml] |
+
+> **Material Icons in CMP caveat:** the JetBrains CMP `material3` artifact (already in catalog) bundles a baseline icon set, but `Icons.Outlined.MenuBook` / `Icons.Outlined.Inventory2` / `Icons.Outlined.CalendarMonth` / `Icons.Outlined.ShoppingCart` are in the **extended** icon set. CMP exposes this via `org.jetbrains.compose.material:material-icons-extended` (or pulls them transitively from `material3`). **Plan needs to verify** whether the four icons referenced in UI-SPEC are available without adding `material-icons-extended`, and add the dependency if not. [ASSUMED — needs Wave-0 verify step]

+
+### Alternatives Considered
+
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| `navigation-compose` (CMP port) | Decompose, Voyager | Both are popular but **locked away by CLAUDE.md** — JetBrains CMP nav is the canonical choice |
+| Compose Unstyled | Roll our own renderless layer | Hand-rolling means re-implementing focus/a11y/keyboard/state semantics. Compose Unstyled exists for this exact reason |
+| Liquid (RuntimeShader) | Native SwiftUI material via interop | Native interop is v2 (LG2-01); Liquid is the v1 approximation per PROJECT.md |
+| Haze fallback | Skip middle tier (Liquid → flat) | CONTEXT D-16 explicitly chose three-tier — middle quality matters when Liquid fails on a target but blur still works |
+
+### Installation
+
+Add to `gradle/libs.versions.toml`:
+```toml
+[versions]
+navigation-compose = "2.9.2"
+compose-unstyled = "1.49.9"
+liquid = "1.1.1"
+haze = "1.6.10"  # confirm latest 1.x stable at planning time
+
+[libraries]
+navigation-compose = { module = "org.jetbrains.androidx.navigation:navigation-compose", version.ref = "navigation-compose" }
+compose-unstyled = { module = "com.composables:composeunstyled", version.ref = "compose-unstyled" }
+liquid = { module = "io.github.fletchmckee.liquid:liquid", version.ref = "liquid" }
+haze = { module = "dev.chrisbanes.haze:haze", version.ref = "haze" }
+```
+
+Then in `composeApp/build.gradle.kts` `commonMain.dependencies`:
+```kotlin
+implementation(libs.navigation.compose)
+implementation(libs.compose.unstyled)
+implementation(libs.liquid)
+implementation(libs.haze)
+```
+
+**Version verification step (Wave 0):** before locking, run `./gradlew dependencies --configuration commonMainRuntimeClasspath | grep -E "(navigation-compose|composeunstyled|liquid|haze)"` to confirm resolution succeeds for both `iosArm64` and `iosSimulatorArm64`. [ASSUMED — Liquid 1.1.1 ships iOS klibs based on Maven Central listing of `liquid-iossimulatorarm64` artifact, but the published target matrix is not enumerated on the package page. Wave 0 must confirm.]

+
+`composeApp/src/iosMain/` and `androidMain/`: backend `actual`s for `GlassBackend` if implementation differs by platform. Liquid is multiplatform so a single `commonMain` `LiquidBackend` likely works; only Haze actuals or platform-specific image effects need `actual`s — confirm at planning.
+
+### Pattern 1: Nested NavHost per tab (CMP-official, multi-back-stack)
+
+Single root `NavHost` containing four `navigation(route = "*_graph")` sub-graphs. Bottom dock navigation uses save/restore state. This is the JetBrains-recommended pattern (kotlinlang.org/docs/multiplatform/compose-navigation.html — "for apps with bottom navigation you can maintain separate nested graphs for each tab while saving and restoring navigation states when switching between tabs").
+
+```kotlin
+// Source: kotlinlang.org/docs/multiplatform/compose-navigation.html (HIGH)
+// + saurabhjadhavblogs.com/jetpack-compose-bottom-navigation-nested-navigation-solved (MEDIUM)
+
+@Serializable data object PlannerGraph
+@Serializable data object PlannerHome
+@Serializable data object RecipesGraph
+@Serializable data object RecipesHome
+// ... etc
+
+@Composable
+fun RootNavHost(navController: NavHostController) {
+    NavHost(navController = navController, startDestination = PlannerGraph) {
+        navigation<PlannerGraph>(startDestination = PlannerHome) {
+            composable<PlannerHome> { entry ->
+                val parent = remember(entry) {
+                    navController.getBackStackEntry(PlannerGraph)
+                }
+                val vm: PlannerViewModel = koinViewModel(viewModelStoreOwner = parent)
+                PlannerScreen(vm)
+            }
+            // future detail destinations land here
+        }
+        navigation<RecipesGraph>(startDestination = RecipesHome) { /* ... */ }
+        navigation<PantryGraph>(startDestination = PantryHome) { /* ... */ }
+        navigation<ShoppingGraph>(startDestination = ShoppingHome) { /* ... */ }
+    }
+}
+
+fun NavHostController.navigateToTab(graphRoute: Any) {
+    navigate(graphRoute) {
+        popUpTo(graph.findStartDestination().id) { saveState = true }
+        launchSingleTop = true
+        restoreState = true
+    }
+}
+```
+
+**iOS caveat (PITFALL 13 + research/PITFALLS.md):** The CMP nav backstack persistence has had issues across minor versions (see GitHub issue 4735 — "Support saving state for nested NavHostController"). Pin to 2.9.2 (latest stable) and verify multi-back-stack behavior on iOS during Wave 0 with a short demo: open detail → switch tab → switch back → confirm detail restored. [VERIFIED: github.com/JetBrains/compose-multiplatform/issues/4735 — issue references nested NavHostController; root-level multi-back-stack via single NavHost + `navigation` blocks is the working pattern]
+
+### Pattern 2: Per-tab ViewModel scoping via parent graph `NavBackStackEntry`
+
+`koinViewModel()` defaults to scoping to the *current* destination entry — meaning the VM dies when you navigate to a child destination. To make `RecipesViewModel` survive within the recipes graph (so future `RecipesDetailScreen` can share state with `RecipesScreen`), retrieve the **parent graph's** `NavBackStackEntry` and pass it as `viewModelStoreOwner`.
+
+```kotlin
+// Source: insert-koin.io/docs/reference/koin-compose/compose/ (HIGH)
+// + droidcon.com/2024/10/16/place-scope-handling-on-auto-pilot-with-koin-compose-navigation (MEDIUM)
+
+@Composable
+fun RecipesScreen(navController: NavController) {
+    val parent = remember { navController.getBackStackEntry(RecipesGraph) }
+    val vm: RecipesViewModel = koinViewModel(viewModelStoreOwner = parent)
+    val searchVm: RecipesSearchViewModel = koinViewModel(viewModelStoreOwner = parent)
+    // both VMs survive within the recipes graph; freed when graph leaves stack
+}
+```
+
+This phase only has one screen per graph, but **set the pattern now** — Phase 5 (Recipe Catalog) will add detail screens that need shared state with the list screen, and Phase 5 should not have to refactor scoping.
+
+### Pattern 3: `GlassSurface` primitive with three-backend chain (D-16, D-17)
+
+```kotlin
+// Source: research synthesis from CONTEXT D-16/D-17 + Liquid README + Haze docs (MEDIUM — Liquid API is from README)
+
+@Composable
+fun GlassSurface(
+    modifier: Modifier = Modifier,
+    tint: Color = RecipeTheme.colors.surfaceGlass,
+    cornerRadius: Dp = 28.dp,
+    border: BorderStroke? = BorderStroke(1.dp, RecipeTheme.colors.borderCard),
+    content: @Composable BoxScope.() -> Unit,
+) {
+    val backend = LocalGlassBackend.current  // resolved via compile-time + debug toggle
+    when (backend) {
+        GlassBackend.Liquid -> LiquidGlassSurface(modifier, tint, cornerRadius, border, content)
+        GlassBackend.Haze -> HazeGlassSurface(modifier, tint, cornerRadius, border, content)
+        GlassBackend.Flat -> FlatGlassSurface(modifier, tint, cornerRadius, border, content)
+    }
+}
+```
+
+`LocalGlassBackend` is a `CompositionLocal` set once at `AppShell` startup:
+1. **Compile-time default** picked per target via `expect/actual` or `commonMain` constants — e.g. `iosArm64/iosSimulatorArm64/android → Liquid`, anything else → `Haze`.
+2. **Debug runtime override** read once at app start from `multiplatform-settings` key `"debug.glass_backend"`. Production builds short-circuit this path (compiled out via `BuildConfig`-style constant in `androidMain` / Kotlin `expect val isDebug` actual).
+
+The Liquid path uses `rememberLiquidState()` + `Modifier.liquefiable(state)` on the content layer behind chrome and `Modifier.liquid(state)` on the chrome itself. The Liquid effect needs a sampleable backdrop, so the screen content (tab body) gets `liquefiable(state)` and the dock/search-pill get `liquid(state)`. **Important:** that backdrop is the screen body, not scrolling content within the body — that aligns with PITFALL 5/12 (chrome-only constraint).
+
+### Pattern 4: Search affordance state machine
+
+```kotlin
+// Source: synthesized from CONTEXT D-05 through D-09 + UI-SPEC interaction contract
+
+class RecipesSearchViewModel : ViewModel() {
+    private val _state = MutableStateFlow(SearchState())
+    val state: StateFlow<SearchState> = _state.asStateFlow()
+
+    fun open() { _state.update { it.copy(isOpen = true) } }
+    fun close() { _state.update { SearchState() } }     // D-08: clears query
+    fun onQueryChange(q: String) { _state.update { it.copy(query = q) } }
+    fun clear() { _state.update { it.copy(query = "") } }
+}
+
+data class SearchState(val isOpen: Boolean = false, val query: String = "")
+```
+
+`AppShell` reads the search VM of the **active** tab (Recipes or Pantry). When `isOpen = true`, the `DockBar` collapses + `SearchPill` renders. The shell owns the active-tab → search-VM mapping; the VMs themselves are scoped to their parent graphs.
+
+**Phase 5 extension point:** the Recipes search VM's state today is `(isOpen, query)`. Phase 5 adds `results: Flow<List<RecipeCard>>` derived from `query.debounce().flatMapLatest { repo.search(it) }`. Design the VM constructor with a nullable `searchSource: SearchSource? = null` parameter today so Phase 5 only injects the dependency rather than rewriting the VM.
+
+### Anti-Patterns to Avoid
+
+- **`when (selectedTab) { ... }` switch instead of nested `NavHost`:** kills back stacks (PITFALL 13). Always use `navigation()` sub-graphs.
+- **`koinViewModel()` without `viewModelStoreOwner` for tab-scoped VMs:** VM dies when navigating into a detail; future Phase 5 detail flow loses list scroll position.
+- **Glass effects over scrolling content:** explicit project rule (CLAUDE.md #10, PITFALL 5/12). `GlassSurface` is for chrome only — dock, search pill, floating button.
+- **Direct Liquid/Haze API calls in screen code:** screens MUST go through `GlassSurface`. Direct calls leak backend choice into call sites and break the fallback contract.
+- **Hardcoded Polish strings:** every user-facing string is `stringResource(Res.string.*)`. CLAUDE.md non-negotiable #9.
+- **`androidx.compose.material3.*` imports outside `ui/screens/auth/`:** PROJECT decision. Even if convenient, it expands Material 3 into new code.
+- **Device clock for animation timing:** unrelated to LWW but same hygiene — use `kotlinx.coroutines` `delay` and Compose animation specs, not `System.currentTimeMillis()`.

+
+## Don't Hand-Roll
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Tab navigation with multi-back-stack | `when (selectedTab)` + manual back-handler | CMP `navigation-compose` 2.9.x with `popUpTo + saveState + restoreState + launchSingleTop` | PITFALL 13: hand-rolled tab switching loses back stack on every switch; Jetpack/JetBrains nav handles it correctly |
+| Renderless TabGroup / Button / TextField with proper a11y + focus + keyboard | Custom `Modifier.clickable + Role.Tab` and an `OutlinedTextField` analogue | Compose Unstyled `TabGroup`, `Button`, `TextField` primitives | These libraries already handle focus order, semantics, IME types, and edge cases; PROJECT decision is to use them |
+| Glass blur effect | Custom `RenderEffect` per platform | Liquid (`liquid` modifier) → Haze (`hazeChild`) → flat translucent | Cross-platform shader correctness, perf optimization, and graceful degradation — all already in Liquid/Haze |
+| Polish-aware string lookup | Hardcoded literals + manual locale switch | `compose-components-resources` `stringResource(Res.string.*)` | Already wired Phase 2; multi-locale-ready for free |
+| Theme `CompositionLocal` ceremony | Per-component prop drilling | Standard Compose `compositionLocalOf` + `CompositionLocalProvider` pattern | Idiomatic; mirror MaterialTheme's structure |
+| Animated transition between dock states | Manual coroutine + lerp | `Modifier.animateContentSize()` for size + `AnimatedContent` for icon/label visibility, both with shared `animationSpec` | Single-source-of-truth animation; Compose handles intersecting frames |
+
+**Key insight:** every chrome surface (dock, search button, search pill) uses the same `GlassSurface` primitive — the size, shape, and animation differ but the substrate doesn't. Centralizing surface logic now means Phase 10's real-device tuning is a one-file change.

+
+## Common Pitfalls
+
+### Pitfall A: CMP nav-compose multi-back-stack regression on iOS
+
+**What goes wrong:** Tab → detail → other tab → return → detail is gone. Reproduces on iOS, not Android.
+**Why:** Some 2.8.x CMP nav releases had broken state restoration on iOS native; 2.9.x is the recommended floor. CMP's K/N nav implementation has had drift behind Android.
+**How to avoid:** Pin to `navigation-compose 2.9.2`. Add a Wave-0 manual smoke test on iOS simulator: navigate dummy detail in one tab, switch tabs, switch back, assert detail visible.
+**Warning signs:** Works on Android, broken on iOS. Compose Multiplatform GitHub issue 4735 family.
+
+### Pitfall B: ViewModel re-creation on tab reselection
+
+**What goes wrong:** Clicking the active tab re-creates its ViewModel, dropping in-memory state and re-running `init`.
+**Why:** `launchSingleTop = true` + missing `restoreState = true` causes Nav to clear and recreate.
+**How to avoid:** Always include `restoreState = true` AND scope VM to parent graph entry (Pattern 2 above). Verify by adding a counter in `init` and confirming it doesn't tick on tab reselection.
+
+### Pitfall C: Liquid sampleable backdrop missing → effect renders flat
+
+**What goes wrong:** `liquid()` modifier renders nothing because no `liquefiable()` peer is in the tree.
+**Why:** Liquid's pixel-sampling needs a tagged source layer. Forgetting it means the effect has no input.
+**How to avoid:** `AppShell` wraps the screen body region in `Modifier.liquefiable(state)` and the dock + search pill + search button consume `Modifier.liquid(state)` from the same `LiquidState`. Document this contract in `GlassSurface` KDoc.
+
+### Pitfall D: `Icons.Outlined.MenuBook` and friends not in baseline icon set
+
+**What goes wrong:** Compile fails on `Icons.Outlined.MenuBook` / `Inventory2` / `CalendarMonth` / `ShoppingCart` because the four selected icons are in the **extended** set, not the baseline that `material3` ships.
+**How to avoid:** Verify at planning time. If extended set is needed, add `org.jetbrains.compose.material:material-icons-extended` to the catalog. (Wave-0 task: try a dummy compose with all four icons; observe.)
+
+### Pitfall E: Hardcoded literals slip in during shell wiring
+
+**What goes wrong:** Tab labels or empty-state copy gets typed inline as `Text("Planer")` during a quick prototype, then nobody refactors.
+**How to avoid:** Lint/grep gate in plan-checker: any `Text("[A-ZŁĄĆŻŃŚŹŻ]...")` or `Text("[a-zA-Złąćż]+")` in `ui/screens/(planner|recipes|pantry|shopping|shell)/` is a bug. Phase 11 will enforce this globally; introduce the discipline now (CLAUDE.md non-negotiable #9).
+
+### Pitfall F: `safeContentPadding()` interactions with floating dock
+
+**What goes wrong:** Bottom dock either overlaps the home indicator or sits too high above it because `Scaffold`-style content padding gets applied twice (once by parent, once by screen body).
+**How to avoid:** AppShell consumes navigation/IME insets explicitly via `WindowInsets.navigationBars.union(WindowInsets.ime).only(WindowInsetsSides.Bottom)` and applies them to the dock's bottom offset. Screen bodies use `WindowInsets.statusBars` for top inset only. Don't use `safeContentPadding()` on both layers.
+
+### Pitfall G: K/N GC churn on bottom-dock animation (PITFALL 1 carry-over)
+
+**What goes wrong:** Frame hitches on iPhone 11/12-era hardware when dock collapses and the Liquid layer composites.
+**How to avoid:** `kotlin.native.binary.objcDisposeOnMain=false` and `gc=cms` are already set Phase 1 (INFRA-03). Verify in Wave 0 and confirm in any iOS smoke test. If hitches appear, the debug runtime toggle (D-17) lets the user fall back to flat to confirm Liquid is the cause.

+### Example 2: AppShell skeleton
+
+```kotlin

+@Composable
+fun AppShell() {
+    val navController = rememberNavController()
+    val backStack by navController.currentBackStackEntryAsState()

+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Manual `when (tab)` tab switching | CMP `navigation-compose` `navigation()` sub-graphs + `saveState/restoreState` | Stable since nav-compose 2.7+ on Android, 2.8+ on KMP | Multi-back-stack works; PITFALL 13 prevented |
+| `nav-compose` 2.7.x with KMP support hidden behind alpha | `org.jetbrains.androidx.navigation:navigation-compose 2.9.x` (stable port) | 2.9 series | Use 2.9.2; older 2.7/2.8 had iOS state-restoration drift |
+| Material 3 default scaffold for tab apps | Compose Unstyled renderless primitives + custom `RecipeTheme` | Compose Unstyled 1.40+ | Calmer aesthetics, no Material 3 tax — explicit project decision |
+| `Modifier.blur()` for glass | RuntimeShader-based libraries (Liquid, Haze 2.x) | Compose 1.6+ stable RuntimeShader on iOS | Real Liquid Glass approximation cross-platform |
+| Haze 2.0-alpha for shipping | Haze 1.x stable for production | Haze 2.0-alpha01 released 2026-04-29 | Stay on 1.x stable until Haze 2.x is stable; Phase 10 may revisit |
+
+**Deprecated/outdated:**
+- `freeze()`, `@SharedImmutable`, `kotlin.native.concurrent.AtomicReference` — gone since K/N new MM (PITFALL 2).
+- `androidx.navigation:navigation-compose` (Android-only artifact) — for KMP, always use `org.jetbrains.androidx.navigation:navigation-compose`.
+
+---
+
+## Assumptions Log
+
+| # | Claim | Section | Risk if Wrong |
+|---|-------|---------|---------------|
+| A1 | Liquid 1.1.1 publishes klibs for `iosArm64` AND `iosSimulatorArm64` (Maven Central lists `liquid-iossimulatorarm64` artifact, but full target matrix not enumerated on the package page) | Standard Stack / Pitfall A | Wave-0 dependency-resolution check fails for iOS; phase falls back to Haze-as-default at compile time. Plan must include the Wave-0 verify step before depending on Liquid as the iOS default backend. |
+| A2 | `Icons.Outlined.MenuBook`, `Inventory2`, `CalendarMonth`, `ShoppingCart` are accessible without adding `material-icons-extended` (UI-SPEC selected these without flagging) | Standard Stack / Pitfall D | Build fails on import; planner adds `material-icons-extended` to catalog. Cheap to fix. |
+| A3 | The CMP nav-compose 2.9.2 K/N (iOS) binary correctly persists `saveState` across tab reselection (a Wave-0 smoke test must confirm) | Pattern 1 / Pitfall A | If broken: the phase falls back to a single root NavHost without nested graphs, and Phase 5 will need to retrofit. Smoke test catches this in Wave 0. |
+| A4 | Haze 1.x stable on KMP iOS handles `hazeChild` over a non-scrolling backdrop without the iPhone-11 jank pattern (PITFALL 12); restricted to chrome only | Pattern 3 | If jank: production engages the flat fallback per D-17. Acceptable since Liquid is the primary path. |
+| A5 | `multiplatform-settings` is wired in commonMain Koin and accessible from `AppShell` at startup (already pulled in Phase 2 for AuthState) | Pattern 3 — debug toggle | If not: minor Koin wiring tweak. Already in libs catalog so likely fine. |
+| A6 | Compose Unstyled 1.49.x supports KMP iOS targets (artifact name `composeunstyled` not `core`) | Standard Stack | If wrong artifact ID: Wave-0 catches via Gradle resolution failure; planner adjusts. Verify exact 1.49.9 coords against `composables.com/docs/com.composables/core/installation`. |
+| A7 | The CMP `lifecycle-viewmodel-compose` `viewModelStoreOwner` parameter to `koinViewModel()` correctly hosts a VM per parent NavBackStackEntry on iOS (the documented pattern is from Android Jetpack; CMP behavior is assumed equivalent) | Pattern 2 | Test in Wave 0; if VM is recreated on tab switch on iOS, fall back to scoping at root graph (less ideal but functional). |
+| A8 | Empty-state copy strings in UI-SPEC are best-current placeholders, subject to Phase 11 tuning | Code Examples / strings.xml | None — explicitly flagged in UI-SPEC. |
+
+**A1 and A3 are the load-bearing assumptions** — Wave 0 of the plan MUST resolve them before the rest of the work is touched.
+
+---
+
+## Open Questions (RESOLVED)
+
+> Resolved 2026-05-08 by gsd-phase-planner during the plan-set authoring pass for plans 02.1-03 through 02.1-08. Each resolution is reflected in the corresponding plan's mandates.
+
+1. **Should the Liquid runtime debug toggle be exposed in-app (hidden gesture) or as a build flag only?** — **RESOLVED**
+   - What we know: D-17 says "via `multiplatform-settings`, surfaced through a hidden settings entry or build flag" — both are valid.
+   - What's unclear: which one delivers more value at this phase. There's no settings screen yet (Phase 3+).
+   - Recommendation: Build flag only this phase (lightest scaffolding). Defer in-app toggle to whenever a settings screen lands. The `multiplatform-settings`-backed `LocalGlassBackend` plumbing is still built so an in-app toggle is a UI-only change later.
+   - **RESOLUTION:** Debug-build runtime override via `multiplatform-settings` key `"debug.glass_backend"`, gated by `expect val isDebugBuild: Boolean` so production binaries compile out the override path entirely. This aligns with D-17 and is implemented by plan 02.1-03 (GlassBackend.kt + IsDebugBuild.kt expect/actual). No in-app debug-toggle UI this phase; Phase 3+ may add one as a UI-only change once a settings surface exists.
+
+2. **Should the `material-icons-extended` artifact be added preemptively, or wait until the four icons are confirmed missing?** — **RESOLVED**
+   - What we know: UI-SPEC selected `Icons.Outlined.{CalendarMonth,MenuBook,Inventory2,ShoppingCart}`. These are typically in extended.
+   - What's unclear: whether `compose-material3` 1.10.0-alpha05 transitively exposes them.
+   - Recommendation: Wave-0 verification task — try the icons, add the dependency if needed. Document the result.
+   - **RESOLUTION:** Added preemptively in plan 02.1-01 (catalog entry `compose-material-icons-extended = "1.7.3"`) because the four phase-2.1 icons (CalendarMonth, MenuBook, Inventory2, ShoppingCart) plus Search are all in the extended set. Validated empirically by the `linkDebugFrameworkIosSimulatorArm64` acceptance check in plan 02.1-01.
+
+3. **Should `RecipeTheme` re-export `MaterialTheme` for the auth screens, or are they fine on Material 3 defaults?** — **RESOLVED**
+   - What we know: Phase 2 auth screens use `MaterialTheme.colorScheme.surface/typography.headlineSmall`. The current `RecipeTheme.kt` is a Material 3 wrapper. UI-SPEC says auth stays on Material 3 as legacy.
+   - What's unclear: whether expanding `RecipeTheme` into the new token system breaks the existing `MaterialTheme.*` lookups in auth screens.
+   - Recommendation: `RecipeTheme` keeps wrapping `MaterialTheme(colorScheme = ...)` AND adds the new `CompositionLocalProvider` for Recipe tokens. Auth screens continue to read `MaterialTheme.*`; new code reads `RecipeTheme.*`. Both work in the same composition.
+   - **RESOLUTION:** Yes — plan 02.1-02 keeps `MaterialTheme(colorScheme = ...)` wrapping the inner `CompositionLocalProvider(...)`. Legacy auth screens (`LoginScreen.kt`, `PostLoginPlaceholderScreen.kt`, `SplashScreen.kt`) continue to read `MaterialTheme.colorScheme.*` / `MaterialTheme.typography.*`; new shell code reads `RecipeTheme.colors.*` etc. The MaterialTheme wrapper is removed only when the auth screens migrate (out of scope for v1 — CONTEXT line 52 keeps auth screens as legacy by user discretion).
+
+

+
+## Environment Availability
+
+This phase is purely client-side code/config; the only external "tools" are Gradle dependencies, all from Maven Central.
+
+| Dependency | Required By | Available | Version | Fallback |
+|------------|------------|-----------|---------|----------|
+| Maven Central | All new dependencies | ✓ | n/a | — |
+| `org.jetbrains.androidx.navigation:navigation-compose` | UI-03 | ✓ | 2.9.2 | — |
+| `com.composables:composeunstyled` | UI-04, component foundation | ✓ | 1.49.9 | — |
+| `io.github.fletchmckee.liquid:liquid` | UI-04 | ✓ | 1.1.1 | Fall back to Haze (D-16) |
+| `dev.chrisbanes.haze:haze` | UI-04 fallback | ✓ | 1.x stable | Fall back to flat translucent |
+| `gradlew` build for `iosSimulatorArm64` | Smoke test (Wave 0) | (host-dependent — Apple Silicon required) | n/a | Manual check on developer machine |
+
+**Missing dependencies with no fallback:** none for this phase.
+**Missing dependencies with fallback:** the entire Liquid → Haze → flat chain IS the fallback design.
+
+---
+
+## Validation Architecture
+
+### Test Framework
+
+| Property | Value |
+|----------|-------|
+| Framework | `kotlin.test` (commonTest) — already used in Phase 2 (`AuthSessionTest`, `LoginViewModelTest`) |
+| Config file | none — convention plugins handle `recipe.kotlin.multiplatform` |
+| Quick run command | `./gradlew :composeApp:commonTest --tests "dev.ulfrx.recipe.ui.screens.shell.*" --tests "dev.ulfrx.recipe.ui.screens.recipes.*Search*"` |
+| Full suite command | `./gradlew :composeApp:check` |
+| Compose UI test runner | not introduced this phase — feasibility low because Compose UI Test on KMP iOS is still surfacing |
+
+### Phase Requirements → Test Map
+
+| Req ID | Behavior | Test Type | Automated Command | File Exists? |
+|--------|----------|-----------|-------------------|-------------|
+| UI-03 | Tab switch preserves per-tab back stack | manual smoke (iOS simulator) — instrument with logging if needed | `./gradlew :composeApp:linkDebugFrameworkIosSimulatorArm64` then iOS smoke from Xcode | ❌ Wave 0 |
+| UI-03 | `navigateToTab()` extension applies `popUpTo + saveState + launchSingleTop + restoreState` | unit | `./gradlew :composeApp:commonTest --tests "*NavigationTest*"` | ❌ Wave 0 |
+| UI-04 | `GlassSurface` selects Liquid backend on iOS targets at compile time | unit (per-source-set constants) | `./gradlew :composeApp:commonTest --tests "*GlassBackend*"` | ❌ Wave 0 |
+| UI-04 | `GlassSurface` debug-toggle flow honors `multiplatform-settings` value | unit (with `MapSettings` test impl) | `./gradlew :composeApp:commonTest --tests "*GlassBackendOverride*"` | ❌ Wave 0 |
+| UI-09 | `EmptyState` composable: on first launch, all four tabs render their respective empty state without flash | manual smoke (iOS) — observe one launch | n/a | manual |
+| UI-09 | App.kt's `AuthState.Authenticated + currentUser != null` branch resolves to `AppShell`, not `PostLoginPlaceholderScreen` | unit (via state-machine test extending `AuthSessionTest` patterns) | `./gradlew :composeApp:commonTest --tests "*AppShellGateTest*"` | ❌ Wave 0 |
+| UI-10 | `RecipesSearchViewModel`: `open() → onQueryChange("foo") → close()` clears query and resets `isOpen` | unit | `./gradlew :composeApp:commonTest --tests "*SearchViewModelTest*"` | ❌ Wave 0 |
+| UI-10 | `RecipesSearchViewModel`: `clear()` resets only query, keeps `isOpen=true` | unit | (same target) | ❌ Wave 0 |
+| UI-10 | Search affordance is visible on Recipes + Pantry tabs only (D-06) | manual smoke + screenshot per tab | n/a | manual |
+
+### Sampling Rate
+
+- **Per task commit:** `./gradlew :composeApp:commonTest` (existing tests + new tests for that task)
+- **Per wave merge:** `./gradlew :composeApp:check` (lint/spotless + commonTest)
+- **Phase gate:** Full `./gradlew check` green AND a single iOS-simulator smoke run completed by hand: launch → land on Planer empty state → tab through Przepisy / Spiżarnia / Zakupy → open search on Recipes, type a few chars, close → confirm dock collapse animation runs → confirm navigation back stacks survive tab roundtrip (smoke script in `02.1-VALIDATION.md`)
+
+### Wave 0 Gaps
+
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/navigation/NavigationTest.kt` — covers UI-03 nav extension semantics (uses `TestNavHostController` if available; else asserts on the lambda built into `navigateToTab()`)
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackendTest.kt` — covers UI-04 backend selection
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackendOverrideTest.kt` — covers UI-04 debug toggle via `MapSettings`
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/screens/shell/AppShellGateTest.kt` — covers UI-09 (root `App()` routes Authenticated to AppShell, not placeholder)
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/screens/recipes/RecipesSearchViewModelTest.kt` — covers UI-10
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/screens/pantry/PantrySearchViewModelTest.kt` — mirror of recipes search VM test
+- [ ] iOS-simulator smoke runbook captured in `02.1-VALIDATION.md` for tab back-stack + dock-collapse manual verification (UI-03/UI-04/UI-09/UI-10 visible checks)
+- [ ] No new framework install needed — `kotlin.test` already in place.
+
+**Honest note:** automated UI tests for `Compose Multiplatform on iOS` are not solved enough at this phase to be worth the cost. The shell is a shape that benefits from human eyes (animation feel, glass aesthetic, label legibility) more than from snapshot-asserting machinery. ViewModel state machines and pure helper functions are unit-testable; the visible chrome is verified by a manual smoke runbook. Phase 10 is the right place to revisit screenshot/UI testing once the shell stabilizes.

+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH — every library is official, on Maven Central, with verified versions as of 2026-05-08
+- Architecture (nested NavHost + Koin scoping): HIGH — JetBrains-documented pattern; Pitfall 13 codified; Pattern 2 is the canonical Koin recommendation
+- Liquid integration specifics: MEDIUM — public API surface read from README; iOS klibs verified to exist on Maven Central but full device-target matrix not enumerated on package page (Wave-0 dependency-resolution check resolves this)
+- Theme + token scaffold structure: HIGH — standard Compose `CompositionLocal` idiom; UI-SPEC pre-locked the shape
+- Empty-state composable: HIGH — trivial; signature locked by D-13
+- Search state machine: HIGH — pure ViewModel + StateFlow following Phase 2's established pattern
+- Validation Architecture: MEDIUM — automated coverage of pure logic is solid; visible chrome relies on manual smoke given KMP iOS UI-test maturity
+
+**Research date:** 2026-05-08
+**Valid until:** 2026-06-07 (30 days; CMP / nav-compose / Liquid all on stable cadence with no upcoming breaking releases announced)

+# Phase 2.1 — UI Design Contract
+
+> Visual and interaction contract for the App Shell, Navigation & Search Foundation. Generated by gsd-ui-researcher, verified by gsd-ui-checker.
+>
+> **Stack note:** This is a Kotlin Multiplatform + Compose Multiplatform mobile project (iOS-primary, Android secondary). shadcn is not applicable — the design system is built on Composables / Compose Unstyled primitives + a local `RecipeTheme` token scaffold + a `GlassSurface` primitive backed by Liquid → Haze → flat fallback chain.
+
+---
+
+## Design System
+
+| Property | Value |
+|----------|-------|
+| Tool | none (Compose Multiplatform; shadcn is web-only) |
+| Preset | not applicable |
+| Component library | Composables / Compose Unstyled (renderless primitives, locally restyled by Recipe components) |
+| Icon library | Compose Material Icons Outlined (`androidx.compose.material:material-icons-extended`) — Material Icons stays even though the visual layer leaves Material 3; outlined variants align with the calm Liquid-Glass aesthetic |
+| Font | System default (`FontFamily.Default`) for v1; SF Pro on iOS / Roboto on Android via platform default. No custom font shipped this phase. Phase 10 may revisit. |
+| Glass primitive | `GlassSurface` composable in `ui/components/glass/`, layered over Liquid (`io.github.fletchmckee.liquid:liquid`) → Haze (`dev.chrisbanes.haze:haze`) → flat translucent fallback |
+| Theme entry | `dev.ulfrx.recipe.ui.theme.RecipeTheme { content }` providing a `LocalRecipeColors`, `LocalRecipeTypography`, `LocalRecipeSpacing`, `LocalRecipeShapes`, `LocalRecipeGlass` `CompositionLocal` set |
+
+**Material 3 boundary:** Material 3 stays only as legacy auth-screen scaffolding (`PostLoginPlaceholderScreen`, login). New code in `ui/screens/{planner,recipes,pantry,shopping}` and `ui/components/` MUST NOT introduce `androidx.compose.material3.*` imports. Use `RecipeTheme` tokens.

+Declared values (all multiples of 4, all within the standard set {4, 8, 16, 24, 32, 48, 64}):
+
+| Token | Value | Usage |
+|-------|-------|-------|
+| `xs` | 4dp | Icon-to-label gap inside dock pill; chip internal padding |
+| `sm` | 8dp | Compact inline spacing; gap between dock and floating search/action button; floating dock vertical offset above the bottom safe-area; dock vertical padding; inter-tab gap inside dock; empty-state icon-to-headline gap |
+| `lg` | 16dp | Default screen content padding; empty-state headline-to-subline gap; search pill horizontal padding |
+| `xl` | 24dp | Section padding; horizontal screen edge inset for empty-state body |
+| `2xl` | 32dp | Layout-level gaps; vertical breathing room above empty-state block |
+| `3xl` | 48dp | Large vertical separators (e.g. between top safe-area and an empty-state's icon when centered visually rather than mathematically) |
+
+**Revision note (revision 1, 2026-05-08):** CONTEXT D-14 originally locked the scale as `4/8/12/16/24/32`. The 12dp step (`md`) was retired during UI-SPEC verification because no usage in this phase required 12dp specifically — every prior 12dp reference was remapped to 8dp (tighter chrome read more like a native iOS dock cluster). The scale extends upward with `2xl` (32dp) and `3xl` (48dp) so empty-state vertical rhythm has expressive headroom. Re-introduce a 12dp token in a later phase if a real geometric need surfaces in execution; the rest of the system can absorb that without churn.
+
+**Exceptions:**
+- iOS safe-area insets are added on top of these tokens via `WindowInsets.safeContent` — never hardcode status-bar or home-indicator padding.
+- Touch target minimum: 44dp on iOS, 48dp on Android. Dock tab cells and the floating search button MUST satisfy this even if visual padding is smaller — use a transparent expansion via `Modifier.minimumInteractiveComponentSize()` or equivalent.
+- Dock geometry: 56dp expanded height, 44dp collapsed height. These are absolute pixel values driven by touch-target ergonomics, not spacing-scale tokens.
+
+---
+
+## Typography
+
+Four named text styles, two weights (Regular 400, Semibold 600). Use system default font family; let the platform pick SF Pro / Roboto.
+
+| Role | Size | Weight | Line Height | Letter Spacing | Usage |
+|------|------|--------|-------------|----------------|-------|
+| `display` | 28sp | 600 (Semibold) | 1.2 (≈34sp) | -0.2sp | Empty-state headline (the calm, anticipatory line) |
+| `title` | 20sp | 600 (Semibold) | 1.2 (≈24sp) | 0sp | Inline tab title at top of each screen body (no top app bar — D-04) |
+| `body` | 16sp | 400 (Regular) | 1.5 (≈24sp) | 0sp | Empty-state subline; search input value text; default screen body copy |
+| `label` | 13sp | 600 (Semibold) | 1.2 (≈16sp) | 0.1sp | Dock tab labels (always shown, both active + inactive — D-02); chip text |
+
+**Scale enforcement:** No raw `TextStyle(fontSize = ...)` in screen code. All text styles come from `RecipeTheme.typography.{display,title,body,label}`. The `title` role is the only header style this phase ships — there is no `headline` / `h1..h6` cascade because there's no top app bar (D-04) and screens don't yet have multi-level content hierarchy.
+
+**Polish-language readiness:**
+- All four roles must render Polish diacritics (ą, ć, ę, ł, ń, ó, ś, ź, ż) without clipping. Line-height ratios above (1.2 / 1.5) leave headroom for `ą` and `Ż` accents.
+- Long Polish tab labels constrain the `label` role: `Spiżarnia` is the longest (9 chars including diacritic). Dock label cells must accommodate this without truncation at default font scale; with system font scaling at 1.3× the dock may compress label visibility (active-only) — this is acceptable in v1 and revisited in Phase 10.
+
+---
+
+## Color
+
+Light + dark schemes are both defined this phase (CONTEXT D-15) and follow the system setting. The mockup palette is reference, not ported. Tokens are exposed as semantic roles (CONTEXT D-14), never raw hex in screen code.
+
+### Semantic roles (60/30/10 + supporting)
+
+| Role | Light value | Dark value | Usage (60/30/10 mapping) |
+|------|-------------|-----------|--------------------------|
+| `background` | `#F7F5F1` (warm off-white) | `#0F1113` (near-black warm) | **Dominant 60%** — full-screen background behind every tab |
+| `surface` | `#FFFFFF` | `#1A1D21` | **Secondary 30%** — solid card / sheet / search-pill substrate when glass is unavailable (flat fallback) |
+| `surfaceGlass` | `#FFFFFF @ 60% alpha` | `#1A1D21 @ 55% alpha` | Tint layer composited inside `GlassSurface` (dock, search pill, floating action button); the Liquid/Haze blur reads through this |
+| `content` | `#0F1113` | `#F1EFEA` | Primary text on `background` and `surface` |
+| `contentMuted` | `#6B6E73` | `#9AA0A6` | Empty-state subline, inactive tab label, secondary captions |
+| `accent` | `#D97757` (warm terracotta) | `#E48A6E` | **Accent 10%** — see "Accent reserved for" below |
+| `separator` | `#E5E1DA` | `#2A2D31` | Hairline dividers (1dp); inter-tab separators inside dock if used |
+| `borderCard` | `#E5E1DA @ 60% alpha` | `#FFFFFF @ 8% alpha` | Outline on glass surfaces (dock, search pill) for depth in light mode and edge clarity in dark mode |
+| `destructive` | `#C0392B` | `#E57368` | Reserved — no destructive actions exist in this phase, but the token is declared so feature phases (sign-out confirmation, plan-entry deletion) inherit it |
+
+### Accent reserved for
+
+The `accent` color (warm terracotta, 10% of pixel real estate target) is used **only** for:
+
+1. **Active dock tab** — the wider, emphasized active tab cell uses `accent` at full opacity for its icon + label color, on a `surfaceGlass` substrate. Inactive tabs use `contentMuted`.
+2. **Search input caret + selection highlight** — the cursor in the open search pill, and any text-selection range.
+
+Accent is NOT used for:
+- Dividers, borders, separators
+- Empty-state icons (those use `contentMuted` per D-10 — calm, low-saturation)
+- The dock substrate itself (that is `surfaceGlass`, not `accent`)
+- Standard body text
+
+This list is exhaustive for this phase. Future phases extend it — primary CTA buttons (Phase 5+), shopping-list checked items (Phase 9), etc.
+
+### 60/30/10 audit (this phase only)
+
+- 60% `background` — yes; the four tab screens are predominantly empty (empty states), so the warm off-white / near-black background dominates.
+- 30% `surface` / `surfaceGlass` — yes; the dock pill, the floating search button, and the search pill are the only substantial non-background surfaces in the shell.
+- 10% `accent` — yes; only the active tab and the search caret carry accent. Quantitatively below 10%, which is correct for a calm shell.
+
+---
+
+## Copywriting Contract
+
+All strings go through Compose Resources (`composeResources/values/strings.xml` or per-locale equivalents). No literal Polish strings in `.kt` files. Resource keys are namespaced by feature: `shell_*`, `empty_*`, `search_*`. Polish copy is the v1 ship language; the resource catalog is multi-locale-ready for Phase 11.
+
+### Tab labels (CONTEXT D-03 — order: Planer, Przepisy, Spiżarnia, Zakupy)
+
+| Resource key | Polish copy | English placeholder (not shipped) |
+|--------------|-------------|-----------------------------------|
+| `shell_tab_planner` | `Planer` | Planner |
+| `shell_tab_recipes` | `Przepisy` | Recipes |
+| `shell_tab_pantry` | `Spiżarnia` | Pantry |
+| `shell_tab_shopping` | `Zakupy` | Shopping |
+
+### Empty states (CONTEXT D-10, D-11 — anticipatory tone, icon + headline + subline, no CTA)
+
+| Tab | Icon (Material Outlined) | Headline (display) | Subline (body) |
+|-----|--------------------------|--------------------|----------------|
+| Planer | `Icons.Outlined.CalendarMonth` | `Twój plan tygodnia czeka` | `Wkrótce zobaczysz tu zaplanowane posiłki.` |
+| Przepisy | `Icons.Outlined.MenuBook` | `Tu pojawi się Twoja książka kucharska` | `Po dodaniu pierwszych przepisów zobaczysz je w tym miejscu.` |
+| Spiżarnia | `Icons.Outlined.Inventory2` | `Spiżarnia jest jeszcze pusta` | `Wkrótce zobaczysz tu wszystko, co masz pod ręką.` |
+| Zakupy | `Icons.Outlined.ShoppingCart` | `Lista zakupów czeka na Twój plan` | `Gdy zaplanujesz tydzień, zobaczysz tu, czego brakuje.` |
+
+Resource keys: `empty_planner_title` / `empty_planner_subtitle`, `empty_recipes_title` / `empty_recipes_subtitle`, `empty_pantry_title` / `empty_pantry_subtitle`, `empty_shopping_title` / `empty_shopping_subtitle`.
+
+**Tone rules:**
+- Forward-looking: "Wkrótce", "Po dodaniu", "Gdy zaplanujesz" — signal the feature is real, not broken.
+- No "Brak danych", no chatty onboarding ("Witaj!"), no exclamation marks.
+- Subline ends with a period. Headline does not.
+- No CTA buttons (CONTEXT D-12). The `EmptyState` composable's `action` slot is reserved unused this phase (D-13).
+
+**Phase 11 caveat:** copy may be tuned during the localization pass. Resource keys above are the contract; copy strings are best-current.
+
+### Search affordance (CONTEXT D-06 through D-09)
+
+| Resource key | Polish copy | Purpose |
+|--------------|-------------|---------|
+| `search_open_a11y` | `Otwórz wyszukiwanie` | Content description for the floating search-icon button (icon-only) |
+| `search_close_a11y` | `Zamknij wyszukiwanie` | Content description for the collapsed dock toggle when search is open (D-05) |
+| `search_clear_a11y` | `Wyczyść` | Content description for the clear button inside the search pill (visible when query is non-empty) |
+| `search_placeholder_recipes` | `Szukaj przepisów…` | Search pill placeholder on Przepisy tab |
+| `search_placeholder_pantry` | `Szukaj w spiżarni…` | Search pill placeholder on Spiżarnia tab |
+
+Search body content: **none** (CONTEXT D-07). No "no results" copy this phase. Phase 5 wires real result rendering. Empty `SearchSurface` body renders an empty `Box` matched to `background`.
+
+### Error / sign-out (out of scope for this phase but tokens reserved)
+
+This phase introduces no error surfaces (auth errors are Phase 2 territory; sync errors are Phase 4+) and no destructive actions. The `destructive` color and a future `confirm_signout_*` resource family are NOT defined here — they ship with their owning phase.
+
+### CTA / primary action
+
+This phase has **no primary CTA button**. The shell is navigation chrome and empty surfaces. The `accent` color contract above declares accent reservation; the first real primary CTA ships in Phase 5 (recipe browse).
+
+---
+
+## Component Inventory (this phase)
+
+Composables introduced in `composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/ui/`:
+
+| Composable | Path | Built on | Visual contract |
+|-----------|------|----------|-----------------|
+| `RecipeTheme` | `ui/theme/RecipeTheme.kt` | CompositionLocal scaffold | Provides `RecipeColors`, `RecipeTypography`, `RecipeSpacing`, `RecipeShapes`, `RecipeGlass` to descendants |
+| `GlassSurface` | `ui/components/glass/GlassSurface.kt` | Liquid → Haze → flat | Single primitive consumed by dock, search pill, floating buttons. Same token API across all three backends (color, opacity, radius). Compile-time backend selection per target; debug-build runtime toggle (CONTEXT D-16, D-17) |
+| `AppShell` | `ui/screens/shell/AppShell.kt` | Compose Unstyled `Scaffold`-equivalent | Auth-gated root: hosts root NavHost + the bottom dock + the floating search/action surface. Renders `background` color edge-to-edge under safe-area insets. |
+| `DockBar` | `ui/components/dock/DockBar.kt` | Compose Unstyled `TabGroup`-equivalent + GlassSurface | Floating bottom pill, 4 tabs (icon + label always — D-02), active tab wider with `accent` foreground; collapses to single circular icon-only toggle when `searchOpen == true` (D-05). Capsule shape: full-pill (height/2 corner radius). Height: 56dp; collapsed height: 44dp. |
+| `FloatingSearchButton` | `ui/components/dock/FloatingSearchButton.kt` | Compose Unstyled `Button` + GlassSurface | 44dp circular glass button, search icon (`Icons.Outlined.Search`) tinted `content`. Adjacent to dock with `sm` (8dp) gap. Visible only on Przepisy + Spiżarnia tabs (D-06). Hidden when `searchOpen == true`. |
+| `SearchPill` | `ui/components/search/SearchPill.kt` | Compose Unstyled `TextField` (renderless) + GlassSurface | Inline bottom search pill (D-09). Capsule shape. Holds: leading search icon, text input (placeholder per tab), trailing clear button (visible when query non-empty). Substrate: `surfaceGlass`. Body content behind it stays visible. Height: 44dp. |
+| `EmptyState` | `ui/components/empty/EmptyState.kt` | Plain Compose | Reusable `EmptyState(icon: ImageVector, title: String, subtitle: String, action: (@Composable () -> Unit)? = null)` — D-13. Vertical center on screen. Icon 48dp tinted `contentMuted`. Spacing: icon → 8dp (`sm`) → headline (`display`) → 16dp (`lg`) → subline (`body`, color `contentMuted`). `action` slot is below subline at 24dp (`xl`) gap when present; unused this phase. |
+| `Screen scaffolds` | `ui/screens/{planner,recipes,pantry,shopping}/{Tab}Screen.kt` | `RecipeTheme` + `EmptyState` | Each: inline tab title at top in `title` style + `lg` padding, then centered `EmptyState`. Background: `RecipeColors.background`. |
+
+**Renderless primitive boundary:** Where Compose Unstyled provides a renderless primitive (button, text field, tab group), Recipe components MUST consume it and apply local styling, not implement the gesture/a11y semantics from scratch. This is the explicit project decision (PROJECT.md § Components: Composables / Compose Unstyled).
+
+---
+
+## Interaction Contracts
+
+### Dock state machine (CONTEXT D-05)
+
+States:
+- `Expanded` — default. 4-tab pill, all icons + labels visible, active tab wider with `accent` foreground.
+- `Collapsed` — when `searchOpen == true`. Single circular cell showing only the active tab's icon, no label, height 44dp (vs 56dp expanded).
+
+Transition: **single coordinated animation** (not two independent ones — explicit user intent in CONTEXT specifics). Suggested duration: 250ms with a standard easing (e.g. `FastOutSlowInEasing`); planner picks final curves and Phase 10 tunes on real device.
+
+Tapping the collapsed dock = `setSearchOpen(false)` = re-expand + close search.
+
+### Search affordance (CONTEXT D-06 through D-09)
+
+- Visible only on `Przepisy` + `Spiżarnia` tabs.
+- `FloatingSearchButton` tap → `searchOpen = true` → `SearchPill` slides up / fades in, `DockBar` collapses, `FloatingSearchButton` hides. Coordinated with the dock-collapse animation as one motion.
+- Closing: tap collapsed dock OR system back gesture → `searchOpen = false` AND `query = ""` (D-08). Re-opening starts blank.
+- Query state lives in the per-tab `SearchViewModel` (one for Recipes, one for Pantry); no persistence across close, tab-switch, or app launch.
+- Body of search surface: **renders nothing** this phase (D-07). The `SearchPill` overlays the existing tab body; the body remains visible behind it.
+
+### Tab navigation (UI-03 / CONTEXT D-03)
+
+- Default landing tab on first sign-in: `Planer` (D-03 — departs from REQ listing order, which research confirmed non-binding).
+- Tab order in dock (left→right): Planer / Przepisy / Spiżarnia / Zakupy.
+- Each tab owns an independent nested `NavHost` (CONTEXT D-03 + research ARCHITECTURE recommendation), so future detail screens preserve back stacks per tab.
+- Tab switch preserves the destination tab's back stack; selecting an already-active tab pops to its root (standard mobile pattern).
+- No tab-bar hide-on-scroll behavior this phase (deferred — CONTEXT § Deferred).
+
+### Accessibility
+
+- Each dock tab cell: `Modifier.semantics { role = Role.Tab; selected = isActive; contentDescription = "$tabLabel${if (isActive) ", aktywna" else ""}" }`.
+- `FloatingSearchButton`: `contentDescription = stringResource(Res.string.search_open_a11y)`.
+- Collapsed dock toggle: `contentDescription = stringResource(Res.string.search_close_a11y)`.
+- Search pill clear button: `contentDescription = stringResource(Res.string.search_clear_a11y)`; visible only when query is non-empty.
+- Touch targets: dock tab cells and the floating search button MUST be ≥ 44dp on iOS, ≥ 48dp on Android.
+- Focus order when search opens: search input field receives focus on open; soft keyboard appears; the collapsed dock toggle is in the tab order after the clear button.
+- Empty-state regions: `Modifier.semantics(mergeDescendants = true) { ... }` so VoiceOver reads the headline + subline as one announcement, not two.
+
+---
+
+## Glass / Liquid contract
+
+`GlassSurface` is the only entry point to glass effects this phase. Direct calls to Liquid or Haze APIs from screen code are forbidden — those only live inside `GlassSurface`'s internal backend selection.
+
+### Backend selection
+
+| Backend | When engaged | Notes |
+|---------|--------------|-------|
+| Liquid | Default on iOS + Android where Liquid 1.1.x compiles cleanly for the target | Pixel-sampling refractive approximation; matches PROJECT decision and CLAUDE.md convention #10 |
+| Haze | Compile-time fallback if Liquid does not ship for a target, OR runtime debug-toggle override | Plain blur; no refraction |
+| Flat | Compile-time fallback if neither Liquid nor Haze is available, OR debug-toggle override | Solid translucent surface using `surfaceGlass` token; no blur |
+
+Selection mechanism (CONTEXT D-17):
+- **Compile-time per target:** the build picks the backend at build time. No runtime branch in production binaries.
+- **Runtime debug toggle (debug builds only):** stored via `multiplatform-settings`, surfaced through a hidden settings entry or build flag. Lets the developer switch backends on-device for visual comparison.
+
+### Surface parameters
+
+The dock, search pill, and floating search button all consume the same token API:
+
+| Parameter | Value | Notes |
+|-----------|-------|-------|
+| Tint color | `surfaceGlass` (light: white@60%, dark: dark@55%) | Composited inside the glass effect |
+| Corner radius | 28dp for the dock pill (full-pill at 56dp height); 22dp for the collapsed dock toggle (full-pill at 44dp); 22dp for the search pill (full-pill at 44dp); 22dp for the floating search button (full-circle at 44dp) | All chrome elements are pill / circle, never rectangular |
+| Border | 1dp `borderCard` outline | Provides edge clarity especially in dark mode |
+| Elevation / shadow | Soft drop shadow: y-offset 8dp, blur 24dp, opacity 12% in light mode; opacity 0% (no shadow, just border) in dark mode | Applied via `Modifier.shadow()` outside the glass clip |
+| Blur radius (Liquid + Haze) | Initial value: 24dp. Phase 10 tunes on real device. Planner may pick library-specific equivalent. |
+| Refraction (Liquid only) | Library default initially; tune in Phase 10. |
+
+**Chrome-only constraint (CLAUDE.md #10 + PITFALLS Pitfall 5):** Glass surfaces are applied to dock, search pill, and floating search button only. NEVER over scrolling content. The empty-state area, tab body, and any future list rows are flat — no `GlassSurface` wraps them.
+
+### Fallback test plan (informational)
+
+Each backend must render visually distinct but functionally identical chrome. Acceptance: switching the debug toggle between Liquid / Haze / flat keeps the dock, search pill, and floating button in the same geometry, with the same content positioning, only the substrate effect changes.
+
+---
+
+## Layout & Safe Area
+
+- Root container: full-screen, edge-to-edge. `WindowInsets.statusBars` is consumed by tab body content (top inset added to the inline tab title's top padding). `WindowInsets.navigationBars` + iOS home-indicator inset are consumed by the dock's bottom offset.
+- The dock floats `sm` (8dp) above the bottom safe-area inset. The search pill and floating search button sit at the same vertical baseline as the dock when active.
+- iOS keyboard avoidance: when the search input has focus, the search pill animates above the soft keyboard via `imeAnimationSource` / `imePadding()`. The dock's collapsed toggle rides up with it (single coordinated motion).
+- No top app bar (D-04). The inline tab title sits at the top of each screen body with `xl` (24dp) top padding above the status-bar inset, then `lg` (16dp) below before screen content (or before the empty-state vertical centering region).
+
+---
+
+## Registry Safety
+
+| Registry | Blocks Used | Safety Gate |
+|----------|-------------|-------------|
+| shadcn official | none — not applicable (Compose Multiplatform stack) | not required |
+| Compose Unstyled (`composables.com`) | renderless primitives (Button, TextField, TabGroup-equivalent) — locally restyled by Recipe components | not required (first-party renderless library; no third-party code lifted into the project) |
+| Liquid (`io.github.fletchmckee.liquid:liquid`) | consumed as a Gradle dependency, not as copied source | dependency review passed — date 2026-05-08; no source code lifted |
+| Haze (`dev.chrisbanes.haze:haze`) | consumed as a Gradle dependency, not as copied source | dependency review passed — date 2026-05-08; no source code lifted |
+
+No third-party shadcn registries declared. No source-code blocks vended into the repo. Standard Gradle dependency review applies.
+
+---
+
+## Out-of-Scope Boundaries (this UI-SPEC)
+
+These intentionally have no contract here and are owned by later phases:
+
+- Recipe list rendering, grid spec, card style — Phase 5
+- Real planner grid, day cells, slot cells — Phase 6
+- Pantry inventory rows, category headers — Phase 8
+- Shopping list rows, checked-state styling, category groupings — Phase 9
+- Theme polish (final color palette tuning, custom font) — Phase 10
+- Animation curves and durations beyond the dock-collapse 250ms default — Phase 10 tunes on real device
+- Real-device Liquid parameter tuning (refraction strength, specular highlights) — Phase 10
+- Polish copy final pass — Phase 11
+- Profile / settings / sign-out chrome placement — Phase 3 onward (no top bar exists yet — D-04)

+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/navigation/NavigationTest.kt` — stubs for V-01 (UI-03 navigateToTab semantics; uses `TestNavHostController` if available, else asserts on the option-builder lambda)
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackendTest.kt` — stubs for V-02 (UI-04 compile-time backend selection)
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/components/glass/GlassBackendOverrideTest.kt` — stubs for V-03 (UI-04 settings-driven debug override)
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/screens/shell/AppShellGateTest.kt` — stubs for V-04 (UI-09 App.kt routing)
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/screens/recipes/RecipesSearchViewModelTest.kt` — stubs for V-05/V-06 (UI-10)
+- [ ] `composeApp/src/commonTest/kotlin/dev/ulfrx/recipe/ui/screens/pantry/PantrySearchViewModelTest.kt` — stubs for V-07 (UI-10 mirror)
+- [ ] iOS-simulator smoke runbook (see § Manual-Only Verifications) committed alongside the phase artifacts so V-08…V-11 have a repeatable check
+- [ ] No new framework install — `kotlin.test` is already wired through `recipe.kotlin.multiplatform` convention plugin
+- [ ] Wave 0 dependency-resolution checks for the three load-bearing assumptions A1/A2/A3 (Liquid iOS klib resolves, Material Icons Outlined available without `material-icons-extended`, nav-compose 2.9.2 K/N back-stack save/restore on iOS)

+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Each tab's empty state renders without flash on first launch | UI-09 | Compose Multiplatform on iOS lacks mature snapshot/UI testing for chrome-level visual verification | iOS sim cold launch → land on Planer (default tab) → confirm intentional empty illustration + copy → no spinner/flash |
+| Tab back-stack preserved across reselection | UI-03 | Real navigation behavior across nested NavHosts is best validated visibly on the simulator | Navigate Przepisy → tap any future stub detail nav → switch to Spiżarnia → switch back to Przepisy → expect previous state restored, not start dest |
+| Search affordance is functional and scoped | UI-10 | UX of opening/closing/clearing must be felt, not just unit-asserted | On Recipes tab: tap search icon → surface opens → type "abc" → confirm query state → tap clear → query empty, surface still open → tap close → surface dismissed. Repeat on Pantry. Confirm Planer/Zakupy do NOT show search affordance. |
+| Liquid dock/menu chrome on iOS device path | UI-04 | Glass aesthetic and performance can only be judged by eye | iOS sim run with default config → confirm Liquid menu/dock renders with the expected glass treatment → toggle debug override via `multiplatform-settings` storage → confirm flat fallback activates |
+| Dock collapse animation on tab change | UI-04 / UI-09 | Animation feel | Tab between all four destinations → confirm dock animation runs smoothly, no jank |

+# 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).

+
+## 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.

+ * Nav 3 host for the 4-tab shell. Renders **one** [NavDisplay] for the active
+ * tab, swapped via [AnimatedContent] when [TabNavigator.activeTab] changes.
+ *
+ * ## Why one display per active tab, not one shared display
+ * Nav 3's [NavDisplay] takes a single back stack. A shell with parallel tab
+ * stacks therefore needs either:
+ *  - one display that re-keys when the tab changes (this implementation), or
+ *  - four always-composed displays stacked z-order, alpha-toggled by tab.
+ *
+ * The re-keyed approach matches the reference [To-Do-CMP](https://github.com/stevdza-san/To-Do-CMP)
+ * structure 1:1, gives a clean 180 ms cross-fade between tabs, and avoids the
+ * predictive-back-handler arbitration headache that comes with multiple live
+ * NavDisplays competing for the gesture (see `NavDisplay.kt` source —
+ * `NavigationBackHandler` is enabled when `previousEntries.isNotEmpty()`, which
+ * is per-display and would mis-fire if multiple displays were alive at once).
+ *
+ * ## ViewModel lifetime
+ * No `rememberViewModelStoreNavEntryDecorator` is installed, so `koinViewModel`
+ * inside `entry<…>` resolves through the **host** `ViewModelStoreOwner`
+ * (Android: the Activity; iOS: the root Compose owner). That keeps tab VMs
+ * alive across tab switches even though the per-tab [NavDisplay] is unmounted
+ * during cross-fade — matches the previous Nav-2 multi-back-stack behaviour
+ * (`saveState=true`/`restoreState=true`).
+ *
+ * Recipe detail is a modal bottom sheet (not a nav destination), so it needs no
+ * per-entry VM scope here; its VM is hosted by the surface that opens it.
+ *
+ * ## Search note
+ * Search is a shell-wide overlay (see `AppShell` + `ShellSearchViewModel`), not
+ * a tab destination — it lives outside this NavDisplay entirely.

+ * Reusable calendar surface for planner, pantry, and shopping. One swipe-able
+ * paged carousel of week strips or month grids, plus an optional chevron to
+ * toggle between the two modes.
+ *
+ * The composable is **controlled** — anchor/selection/mode live in the
+ * caller's state. The pager is local UI state and is re-keyed when [mode]
+ * changes (so the new origin date can be picked up safely).
+ *
+ * @param selectedDate Currently selected day. Defaults to the only highlight
+ *   used by [isSelectedOverride]'s default impl. Tapping the topbar pill jumps
+ *   here.
+ * @param today Used for the "today" outline ring; also the date the topbar
+ *   jumps to when tapped.
+ * @param mode Whether to render week strips or month grids.
+ * @param onSelectDate Called when the user taps a day cell.
+ * @param onModeChange Called when the user taps the expand chevron.
+ * @param onVisibleAnchorChange Called when the user swipes to a new period.
+ *   Receives an anchor inside the now-visible period. The caller usually
+ *   updates [selectedDate] in response (see PlannerViewModel for the pattern).
+ * @param dayState Per-day visual modifiers (dimmed for adjacent-month days is
+ *   added automatically by the month grid).
+ * @param isSelectedOverride Custom selection predicate. Pass for range
+ *   selection; defaults to `date == selectedDate`.
+ * @param expandable When true, renders the chevron and supports mode toggle.
+ *   Popup variants (pantry/shopping) set this to false.
