CAPABILITY_MATRIX

Inter-App Comms Suite — Capability Matrix (v1.0)

Canonical 3-module × KMP-target × per-API support matrix. Cells: ✅ real native impl · ⚠️ fallback (works but not native UX) · ❌ ADR-09 #N WONTFIX (architectural OS limitation) · 🔗 v0.4 PROVISIONAL (compiles; runtime verification pending real-device CI) · ⊘ target not declared.

See cmp-app-intents/adrs/ADR-09-platform-impl-exits.md for the full WONTFIX rationale.

Compose Multiplatform target reach (cmp-intent-launcher-compose): 9 targets — androidLibrary + jvm + iOS×3 + macOS×2 + js + wasmJs. tvOS/watchOS/Linux/mingw consumers use the core cmp-intent-launcher module's imperative IntentLauncher class directly (Compose Multiplatform doesn't ship compose.runtime for those targets — Phase 0 S1.A verdict UNCHANGED).

cmp-intent-launcher SystemIntents (v0.4 Phase 13 — lifecycle-free entry points)

Callable from commonMain / DI / non-UI code. No Composable / ActivityResultLauncher needed. Android Context auto-injected via IntentLauncherInitProvider.

Target	openAppSettings()	createDocument(name, mime)
androidLibrary	✅ ACTION_APPLICATION_DETAILS_SETTINGS + FLAG_ACTIVITY_NEW_TASK	✅ Invisible proxy Activity + ActivityResultContracts.CreateDocument
jvm	✅ OS-aware ProcessBuilder	✅ JFileChooser SAVE_DIALOG on EDT (via Dispatchers.IO)
iosX64 / iosArm64 / iosSimulatorArm64	✅ UIApplicationOpenSettingsURLString	✅ UIDocumentPickerViewController (ExportToService) + DelegatePin
macosX64 / macosArm64	✅ x-apple.systempreferences	✅ NSSavePanel.runModal()
tvosX64 / tvosArm64 / tvosSimulatorArm64	❌ #5	❌ #5
watchosX64 / watchosArm32 / watchosArm64 / watchosSimulatorArm64 / watchosDeviceArm64	❌ #6	❌ #6
linuxX64 / linuxArm64	✅ gnome-control-center / kcmshell5 / xdg-open chain	✅ zenity --file-selection --save
mingwX64	✅ start ms-settings:appsfeatures	❌ #13 (Win32 GetSaveFileNameW cinterop deferred)
js (browser)	❌ #10 (no app-scoped settings)	✅ window.showSaveFilePicker (Chromium only; ❌ on Firefox/Safari)
wasmJs (browser)	❌ #10	✅ window.showSaveFilePicker via @JsFun (Chromium only)

New ADR-09 rows from v0.4 Phase 13: #13 mingw SystemIntents.createDocument (GetSaveFileNameW cinterop) — WONTFIX-PROVISIONAL until follow-up cinterop expansion.

cmp-app-intents (19 declared) + cmp-app-intents-compose (9 declared)

Target	register()	Runtime registry	OS surface
androidLibrary	✅	✅ in-memory	✅ shortcuts.xml capability tags (BIIs) via Phase 5 generateShortcutsXml Gradle task
jvm	⚠️ no-op	✅ in-memory	❌ #9 architectural
iosX64 / iosArm64 / iosSimulatorArm64	✅	✅ in-memory	✅ Swift bridge + AppShortcutsProvider (per ADR-04) + auto-generated Swift stubs via Phase 5 generateSwiftIntents
macosX64 / macosArm64	✅	✅ in-memory	✅ same as iOS
tvosX64 / tvosArm64 / tvosSimulatorArm64	✅ v0.4 manifest write	✅ in-memory	✅ manifest + Swift bridge (CoreSpotlight no-op via #if canImport guard)
watchosX64 / watchosArm32 / watchosArm64 / watchosSimulatorArm64	✅ v0.4 manifest write	✅ in-memory	✅ manifest + Swift bridge (watchOS 10+ Shortcuts)
linuxX64 / linuxArm64	✅ v0.4 XDG manifest + .desktop	✅ in-memory	✅ .desktop action handlers in $XDG_DATA_HOME/applications/
mingwX64	✅ v0.4 APPDATA manifest	✅ in-memory	🔗 IShellLinkW Start Menu shortcuts deferred to post-v0.4 CI verification
js (browser)	⚠️ no-op	✅ in-memory	❌ #10 architectural (PWA shortcut manifest = separate future cmp-pwa-shortcuts module)
wasmJs (browser)	⚠️ no-op	✅ in-memory	❌ #10 architectural

Compose Multiplatform target reach (cmp-app-intents-compose): same 9 as above. Consumers use AppIntentsRegistration(config) Composable for lifecycle-bound registration + AppIntentsRegistry() for Material 3 styled dev/debug UI.

ADR-09 status at v1.0 ship

12 v0.4 candidate rows from v0.3-alpha:

• ✅ CLOSED: #1 (tvOS partial Swift bridge wiring); #2 (watchOS transferFile); #3 (mingw CF_DIB cinterop); #4 (JVM OS-detect ProcessBuilder); #8 (mingw GetOpenFileNameW cinterop); #11 (all 4 tier-3 manifest writes); #12 (Gradle codegen tasks).
• WONTFIX (architectural): #5 (tvOS picker surface non-existent); #6 (watchOS picker surface non-existent); #7 (Linux contact-picker absent); #9 (JVM Desktop no canonical intent surface); #10 (JS/wasmJs no canonical Web intent surface — PWA shortcuts = future module).

See ADR-09 for the per-row rationale + post-v1.0 follow-up guidance.

Compose vs non-Compose decision tree

Are you using Compose Multiplatform in commonMain?
├── YES  → Add `cmp-{share|intent-launcher|app-intents}-compose` deps
│         Use `rememberShareLauncher()` / `IntentPickerDialog()` /
│         `AppIntentsRegistration()` opinionated Composables
│
└── NO   → Add `cmp-{share|intent-launcher|app-intents}` core deps only
          Use `Share.share(...)` / `IntentLauncher()` /
          `AppIntents.register(...)` imperative APIs directly
