+# Jetpack Compose support (F-013 / GH #96)
+
+Forma enables Compose **per target** (with an optional project-wide default),
+and provides a dedicated **`composeWidget`** target for Compose UI components.
+
+## Project-wide settings
+
+In the root `build.gradle.kts` `buildscript` block:
+
+```kotlin
+androidProjectConfiguration(
+    project = rootProject,
+    minSdk = 21,
+    targetSdk = 33,
+    // compileSdk 34 when using modern Compose transitive AARs
+    compileSdk = 34,
+    agpVersion = "8.1.2",
+    compose = false, // default for per-target flags
+    composeCompilerVersion = "1.5.3", // must match Kotlin (1.9.10 → 1.5.3)
+)
+```
+
+| Setting | Role |
+|---------|------|
+| `compose` | Default value for per-target `compose = …` parameters on `impl`, `androidLibrary`, `androidUtil`, `androidApp`, `uiLibrary`, `androidBinary`. |
+| `composeCompilerVersion` | Written to AGP `composeOptions.kotlinCompilerExtensionVersion` when Compose is enabled. |
+
+`composeWidget` modules **always** enable Compose; they ignore the project default
+(they do not need `compose = true`).
+
+## Per-target `compose` flag
+
+```kotlin
+impl(
+    packageName = "com.example.feature.home.impl",
+    compose = true,
+    dependencies = deps(/* … */),
+)
+
+androidLibrary(
+    packageName = "com.example.shared.ui.library",
+    compose = true,
+)
+
+androidBinary(
+    packageName = "com.example.app",
+    versionCode = 1,
+    versionName = "1.0",
+    compose = true,
+    dependencies = deps(target(":root-app"), /* … */),
+)
+```
+
+When `compose = true`, Forma sets:
+
+- `android.buildFeatures.compose = true`
+- `android.composeOptions.kotlinCompilerExtensionVersion = <composeCompilerVersion>`
+
+You still declare Compose **libraries** yourself (runtime, UI, material, …)
+via catalogs / `deps(...)`. Forma does not inject Compose artifacts automatically.
+
+## `composeWidget` target
+
+Suffix: **`compose-widget`** (project name must end with `-compose-widget` or equal
+`compose-widget`).
+
+```kotlin
+// application/common/greeting/compose-widget/build.gradle.kts
+composeWidget(
+    packageName = "com.example.common.greeting.compose.widget",
+    dependencies = deps(
+        androidx.compose // sample catalog cluster
+    )
+)
+```
+
+Parallel to `widget` (View system). View and Compose may depend on each other:
+
+- `widget` → may depend on `compose-widget`
+- `compose-widget` → may depend on `widget`
+
+so hybrid screens can mix View and Compose (GH #96).
+
+## Who may depend on `compose-widget`
+
+| Consumer | `compose-widget` allowed? |
+|----------|---------------------------|
+| `impl` | yes |
+| `androidApp` / `androidBinary` | yes |
+| `uiLibrary` | yes |
+| `widget` | yes |
+| `composeWidget` | yes (self) |
+| `androidRes` / `viewBinding` | yes (resources/layout wiring) |
+| `api` / JVM `library` / `util` | no |
+
+Full matrix: [`DEPENDENCY-MATRIX.md`](DEPENDENCY-MATRIX.md).
+
+## Compiler / Kotlin pairing
+
+Default `composeCompilerVersion = "1.5.3"` matches Kotlin **1.9.10** (Gradle 8.4
+embedded Kotlin used by the sample). If you bump Kotlin, update
+`composeCompilerVersion` using the
+[Compose Compiler compatibility map](https://developer.android.com/jetpack/androidx/releases/compose-kotlin).

+by `binary` with `compose = true`.

+- **Ticket:** F-013 → `done`

+- **Plugin / DSL:**
+  - `AndroidLibraryFeatureConfiguration.compose` + `AndroidBinaryFeatureConfiguration.compose`
+    → `buildFeatures.compose` + `composeOptions.kotlinCompilerExtensionVersion`
+  - Per-target `compose` flag (default = project `androidProjectConfiguration(compose=…)`)
+    on `impl`, `androidLibrary`, `androidUtil`, `androidApp`, `uiLibrary`, `androidBinary`
+  - New target **`composeWidget`** / suffix `compose-widget` (always Compose)
+  - Project settings: `composeCompilerVersion` (default **1.5.3** for Kotlin 1.9.10)
+  - Validators: `compose-widget` allowed from impl/app/binary/uiLibrary/widget/viewBinding/res;
+    widget ↔ compose-widget mutual deps (View + Compose coexist)
+- **Sample:**
+  - `application/common/greeting/compose-widget` with `@Composable GreetingCard`
+  - `binary` depends on it with `compose = true`
+  - `androidx.compose` catalog cluster (`transitiveDeps`) in build-dependencies
+  - Sample `compileSdk` **34** (Compose emoji2 AAR metadata); `targetSdk` remains 33
+- **Docs:** `docs/COMPOSE.md`; matrix/README/ARCHITECTURE/ENV/CI updated
