### A. UI Development (Jetpack Compose)
- **Material 3:** The app uses Material 3.
- **Strings:** MUST use the **Compose Multiplatform Resource** library in `core:resources` (`stringResource(Res.string.your_key)`). For ViewModels or non-composable Coroutines, use the asynchronous `getStringSuspend(Res.string.your_key)`. NEVER use hardcoded strings, and NEVER use the blocking `getString()` in a coroutine.
+- **String formatting:** CMP's `stringResource(res, args)` / `getString(res, args)` only support `%N$s` (string) and `%N$d` (integer) positional specifiers. Float formats like `%N$.1f` are NOT supported — they pass through unsubstituted. For float values, pre-format in Kotlin using `NumberFormatter.format(value, decimalPlaces)` from `core:common` and pass the result as a `%N$s` string arg. Use bare `%` (not `%%`) for literal percent signs in CMP-consumed strings, since CMP does not convert `%%` to `%`. For JVM-only code using `formatString()` (which wraps `String.format()`), full printf specifiers including `%N$.Nf` and `%%` are supported.
- **Dialogs:** Use centralized components in `core:ui` (e.g., `MeshtasticResourceDialog`).
- **Alerts:** Use `AlertHost(alertManager)` from `core:ui/commonMain` in each platform host shell (`Main.kt`, `DesktopMainScreen.kt`). For global responses like traceroute and firmware validation, use the specialized common handlers: `TracerouteAlertHandler(uiViewModel)` and `FirmwareVersionCheck(uiViewModel)`. Do NOT duplicate inline alert-rendering logic or trigger alerts directly during composition. For shared QR/contact dialogs, use the `SharedDialogs(uiViewModel)` composable.
- **Placeholders:** For desktop/JVM features not yet implemented, use `PlaceholderScreen(name)` from `core:ui/commonMain`. Do NOT define inline placeholder composables in feature modules.

## Executive Summary
-The codebase is **~98% structurally KMP** — 18/20 core modules and 7/7 feature modules declare `jvm()` targets and cross-compile in CI. Shared `commonMain` code accounts for ~52K LOC vs ~18K platform-specific LOC (a 74/26 split). This is strong.
+The codebase is **~98% structurally KMP** — 18/20 core modules and 8/8 feature modules declare `jvm()` targets and cross-compile in CI. Shared `commonMain` code accounts for ~52K LOC vs ~18K platform-specific LOC (a 74/26 split). This is strong.
Of the five structural gaps originally identified, four are resolved and one remains in progress:
1. **`app` is a God module** — originally 90 files / ~11K LOC of transport, service, UI, and ViewModel code that should live in core/feature modules. *(✅ Resolved — app module reduced to 6 files: `MainActivity`, `MeshUtilApplication`, Nav shell, and DI config)*
2. ~~**Radio transport layer is app-locked**~~ — ✅ Resolved: `RadioTransport` interface in `core:repository/commonMain`; shared `StreamFrameCodec` + `TcpTransport` in `core:network`.
3. ~~**`java.*` APIs leak into `commonMain`**~~ — ✅ Resolved: `Locale`, `ConcurrentHashMap`, `ReentrantLock` purged.
-4. ~~**Zero feature-level `commonTest`**~~ — ✅ Resolved: 131 shared tests across all 7 features; `core:testing` module established.
+4. ~~**Zero feature-level `commonTest`**~~ — ✅ Resolved: 193 shared tests across all 8 features; `core:testing` module established.
5. ~~**No `feature:connections` module**~~ — ✅ Resolved: KMP module with shared UI and dynamic transport detection.

+## WiFi Provisioning System
+
+The `:feature:wifi-provision` module provides BLE-based WiFi provisioning for Meshtastic devices using the Nymea network manager protocol. It scans for provisioning-capable devices, retrieves available WiFi networks, and applies credentials — all over BLE via the Kable multiplatform library.
+
+### Architecture
+
+- **Protocol:** Nymea BLE network manager (GATT service `e081fec0-f757-4449-b9c9-bfa83133f7fc`)
+- **Transport:** BLE via `core:ble` Kable abstractions with chunked packet codec
+- **UI:** Single-screen Material 3 Expressive flow with 6 phases (Idle, ConnectingBle, DeviceFound, LoadingNetworks, Connected, Provisioning)
+
+```mermaid
+sequenceDiagram
+ participant App as Meshtastic App
+ participant BLE as BLE Scanner
+ participant Device as Provisioning Device
+
+ Note over App: Phase 1: Scan
+ App->>BLE: Scan for GATT service UUID

+
+ Note over App, Device: Phase 4: Provision
+ App->>Device: Connect(SSID, password)
+ Device-->>App: NetworkingStatus response
+ App->>Device: Disconnect BLE
+```
+
+### Key Classes
+
+- `WifiProvisionViewModel.kt`: MVI state machine with 6 phases and SSID deduplication.
+- `WifiProvisionScreen.kt`: Material 3 Expressive single-screen UI with Crossfade transitions.
+- `NymeaWifiService.kt`: BLE service layer — connect, scan networks, provision, close.
+- `NymeaPacketCodec.kt`: Chunked BLE packet encoder/decoder with reassembly.
+- `NymeaProtocol.kt`: JSON serialization for Nymea network manager commands and responses.
+- `ProvisionStatusCard.kt`: Inline status feedback card (idle/success/failed) with Material 3 colors.
