Ships v0.5.0 via kmp-manager 6-phase flow. 13 plan tasks (D1, T1-T10, D3, D4), 14 agent calls, 6 P-groups. 107 → 207 tests on iosSimulatorArm64. Toolchain (D1): - Kotlin 2.1.0 → 2.3.21 - Compose-Multiplatform 1.8.0 → 1.11.0 - Android Gradle Plugin 8.7.3 → 9.2.0 - Gradle 8.11.1 → 9.5.1 - coroutines 1.9.0 → 1.11.0, kotlin-test → 2.3.21 - Drop kotlinx-datetime; use stdlib kotlin.time.Clock - Drop iosX64 target (Compose-MP 1.11.0 has no ios_x64 variant) Architecture (T1-T6, T10): - TieredBuffer.snapshotWindow: bisect-based windowed snapshot - New lod/ package: LodStrategy interface + MinMax/Lttb/MinMaxLttb impls (MinMaxLttb SOTA per arXiv 2305.00332, 1.80× faster than pure LTTB) - New render/SignalRenderer: public interface + LineSignalRenderer object - New render/AxisFormatter: 4 default impls (Time, Decimal, DateTime, Unit) - HARD BREAK: deleted LodMode, LodDecimator, ChartConfig.targetFps - ChartConfig split: DataConfig + AxisConfig + RenderConfig + FrameRate sealed - @Immutable/@Stable on all public types (0 unstable) - RealtimeChartState.clear() API Interaction layer (T7): - New interaction/ package - ChartInteractionState + rememberChartInteractionState() - ViewportMode sealed: Following / Frozen / History(anchorMs) - Pinch zoom + drag pan + tap crosshair gestures - Swipe-to-edge resumes Following - InverseProjection: pixel → ms + bisect nearest-sample Perf finishing (T8, T9, D3): - LineSignalRenderer Stroke cache, AxisRenderer TextStyle cache - resolveYRange Pair<Float,Float> → FloatArray out-param - RealtimeChartState.signalsArray cached (invalidated on add/remove only) - LTTB upper-bound aligned to half-open [start, start+windowMs) semantic Correctness (D4): - NumberFormat.formatFixed Long overflow guard @ |v|≥1e19 ABI baseline regenerated: - chart-realtime.api: 161 → 428 LOC - chart-realtime.klib.api: 211 → 501 LOC Modules touched: chart-realtime (lib), app (consumer), gradle (toolchain), .paul (state).
