Android debug detection uses the runtime ApplicationInfo.FLAG_DEBUGGABLE fallback because BuildConfig is not available on this module's Kotlin compile classpath.
Haze 1.6.10 uses Modifier.hazeEffect(state, style) instead of the deprecated hazeChild API, with hazeSource(state) on the backdrop.
multiplatform-settings-test was not added because this wave owns only glass files; the tests use a local Settings fake named MapSettings.
GlassSurface dispatches by LocalGlassBackend while preserving one tint/radius/border call-site API.
GlassBackdropSource hides Liquid/Haze source wiring behind Recipe-owned state.

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.

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.
