Modules: chart-realtime (commonMain, iosMain), root, .paul
- chart-realtime/build.gradle.kts: applyDefaultHierarchyTemplate() + XCFramework("ChartRealtime") over iosX64/iosArm64/iosSimulatorArm64, baseName CamelCase
- commonMain RealtimeChartState/CircularBuffer: switch to kotlin.concurrent.Volatile, add kotlin.jvm.JvmName import (OptionalExpectation)
- commonMain AxisRenderer: replace JVM-only String.format with multiplatform formatFixed/formatScientific/pow10 helpers
- iosMain Platform.ios.kt: NSDate() + timeIntervalSinceReferenceDate + 978_307_200s 1970-epoch offset (K/Native binding has no direct timeIntervalSince1970)
- gradle.properties: remove Linux JDK pin (rely on JAVA_HOME)
- .paul: phases plan, STATE+ROADMAP updates
Acceptance: A1 compile 3 iOS targets, A2 linkDebugFrameworkIosSimulatorArm64, A3 iosSimulatorArm64Test (33 tests, 0 failures), A4 assembleChartRealtimeXCFramework (ios-arm64 + ios-arm64_x86_64-simulator slices), A5 Android assembleRelease/publishToMavenLocal --dry-run.

### Delivered
|
|
|
|
- 3 iOS targets compile green (iosX64, iosArm64, iosSimulatorArm64)
|
|
- `applyDefaultHierarchyTemplate()` wires iosMain/iosTest across targets
|
|
- `linkDebugFrameworkIosSimulatorArm64` green
|
|
- `iosSimulatorArm64Test` green — 33 tests, 0 failures
|
|
- XCFramework `ChartRealtime` produced (debug + release): ios-arm64 + ios-arm64_x86_64-simulator slices
|
|
- Pre-existing compile bugs fixed:
|
|
- `@Volatile` → `kotlin.concurrent.Volatile` import
|
|
- `@JvmName` → `kotlin.jvm.JvmName` import (OptionalExpectation)
|
|
