Christian Nennemann 2e081ead8e chore: rename quicproquo → quicprochat in docs, Docker, CI, and packaging
Rename all project references from quicproquo/qpq to quicprochat/qpc
across documentation, Docker configuration, CI workflows, packaging
scripts, operational configs, and build tooling.

- Docker: crate paths, binary names, user/group, data dirs, env vars
- CI: workflow crate references, binary names, artifact names
- Docs: all markdown files under docs/, SDK READMEs, book.toml
- Packaging: OpenWrt Makefile, init script, UCI config (file renames)
- Scripts: justfile, dev-shell, screenshot, cross-compile, ai_team
- Operations: Prometheus config, alert rules, Grafana dashboard
- Config: .env.example (QPQ_* → QPC_*), CODEOWNERS paths
- Top-level: README, CONTRIBUTING, ROADMAP, CLAUDE.md

# QuicProChat Kotlin SDK
Kotlin/JVM wrapper over `libquicprochat_ffi` via JNI for Android and JVM platforms.
## Prerequisites
- Kotlin 1.9+ / JDK 17+
- `libquicprochat_ffi` built for the target architecture
- JNI bridge compiled (`jni/dev_quicprochat_NativeBridge.c`)
## Building the Native Library
```sh
# Linux (JVM)
cargo build --release -p quicprochat-ffi
# Android (aarch64)
cargo build --release -p quicprochat-ffi --target aarch64-linux-android
# Android (armv7)
cargo build --release -p quicprochat-ffi --target armv7-linux-androideabi
```
### Compiling the JNI Bridge
```sh
cd jni
gcc -shared -fPIC -o libquicprochat_jni.so \
-I"$JAVA_HOME/include" -I"$JAVA_HOME/include/linux" \
dev_quicprochat_NativeBridge.c \
-L ../../../../target/release -lquicprochat_ffi
```
## Installation
### Gradle
```kotlin
dependencies {
implementation(files("libs/quicprochat-0.1.0.jar"))
}
```
Or include as a local project module.
## Usage
```kotlin
import dev.quicprochat.QpqClient
val client = QpqClient("127.0.0.1:5001", caCertPath = "ca.pem")
client.login("alice", "secret")
client.send("bob", "hello".toByteArray())
val messages = client.receive(timeoutMs = 5000)
messages.forEach { println("Received: $it") }
client.close()
```
## API
| Method | Description |
|---|---|
| `QpqClient(server, caCertPath, serverName)` | Connect to server |
| `client.login(username, password)` | OPAQUE authentication |
| `client.send(recipient, message)` | Send message by username |
| `client.receive(timeoutMs)` | Receive pending messages |
| `client.close()` / `client.disconnect()` | Disconnect |
| `client.isConnected` | Connection status |
## Error Handling
```kotlin
try {
client.login("alice", "wrong")
} catch (e: QpqAuthException) {
println("Auth failed: ${e.message}")
} catch (e: QpqTimeoutException) {
println("Timeout: ${e.message}")
} catch (e: QpqException) {
println("Error: ${e.message}")
}
```
## Structure
- `src/main/kotlin/dev/quicprochat/QpqClient.kt` -- High-level client
- `src/main/kotlin/dev/quicprochat/NativeBridge.kt` -- JNI declarations
- `src/main/kotlin/dev/quicprochat/QpqError.kt` -- Exception types
- `jni/dev_quicprochat_NativeBridge.c` -- JNI C bridge to FFI
## Android Integration
1. Add the native libraries to `src/main/jniLibs/<abi>/`:
- `arm64-v8a/libquicprochat_ffi.so`
- `armeabi-v7a/libquicprochat_ffi.so`
2. Add the JNI bridge library alongside
3. The `NativeBridge` class loads the library via `System.loadLibrary`
## Cross-Compilation
```sh
# Install Android NDK targets
rustup target add aarch64-linux-android armv7-linux-androideabi
# Build with the NDK linker
CARGO_TARGET_AARCH64_LINUX_ANDROID_LINKER=aarch64-linux-android21-clang \
cargo build --release -p quicprochat-ffi --target aarch64-linux-android
```
