## v0.5.0 — Architecture + Interaction (PLANNED)
|
||||
## v0.5.0 — Architecture + Interaction (SHIPPED)
|
||||
|
||||
Plan: .paul/phases/v0.5.0-architecture-plan.md
|
||||
Effort: 5-7 giorni full-time, ~12 agent calls
|
||||
Prereq: v0.4.0 shipped
|
||||
Plan: .paul/phases/v0.5.0-architecture-plan.md (v2 deltas)
|
||||
Executed via: kmp-manager 6-phase flow, 6 P-groups, ~14 agent calls
|
||||
Completed: 2026-05-21
|
||||
|
||||
### Highlights
|
||||
- Interaction layer S0 (pinch zoom + drag pan + crosshair tap) — fatale senza
|
||||
- LodStrategy/SignalRenderer/AxisFormatter interfaces (apri estensibilità)
|
||||
- MinMaxLTTB SOTA algorithm (10x faster than LTTB puro, arXiv 2305.00332)
|
||||
- Bisect tier snapshot per timestamp window (30x perf win)
|
||||
- ChartConfig split DataConfig/AxisConfig/RenderConfig
|
||||
- FrameRate sealed (replace `targetFps: Int?` nullable-as-sentinel)
|
||||
- Compose @Stable/@Immutable annotations
|
||||
- Cache Stroke + TextStyle + TextLayoutResult (zero-alloc render reale)
|
||||
- Replace Pair<Float,Float> return + Map iter alloc
|
||||
- RealtimeChartState.clear() API
|
||||
### Delivered
|
||||
|
||||
**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
|
||||
- Dropped `kotlinx-datetime`; swapped to stdlib `kotlin.time.Clock` (Kotlin 2.3 stable)
|
||||
- Dropped `iosX64` target (Compose-MP 1.11.0 incompat — Intel Mac sims deprecated)
|
||||
|
||||
**Architecture (T1-T6, T10):**
|
||||
- T1: Bisect tier snapshot (`TieredBuffer.snapshotWindow`) — 26 new tests
|
||||
- T2: `LodStrategy` interface + `MinMaxLodStrategy` + `LttbLodStrategy` + `MinMaxLttbLodStrategy` (SOTA, 1.80× faster than pure LTTB on iOS sim; arXiv 2305.00332 ratio=4)
|
||||
- T3: `SignalRenderer` interface (public) + `LineSignalRenderer` default impl
|
||||
- T4: `AxisFormatter` interface + `TimeAxisFormatter` + `DecimalAxisFormatter` + `DateTimeAxisFormatter` + `UnitAxisFormatter`
|
||||
- T5: **HARD BREAK** — deleted `LodMode` enum + `LodDecimator` + `ChartConfig.targetFps`. Split `ChartConfig` → `DataConfig` + `AxisConfig` + `RenderConfig` + `FrameRate` sealed
|
||||
- T6: `@Immutable`/`@Stable` annotations — 0 unstable public types
|
||||
- T10: `RealtimeChartState.clear()` API
|
||||
|
||||
**Interaction layer (T7):**
|
||||
- `ChartInteractionState` + `rememberChartInteractionState()` hoistable state
|
||||
- `ViewportMode` sealed: `Following` / `Frozen` / `History(anchorMs)`
|
||||
- `CrosshairState` + `SignalValueAt` (List, not Map — zero boxing)
|
||||
- `InteractionConfig` (zoomEnabled/panEnabled/tapCrosshairEnabled + clamps)
|
||||
- Pinch zoom + drag pan + tap crosshair + swipe-to-edge-resumes-Following
|
||||
- `InverseProjection`: pixel→ms + bisect-based nearest-sample
|
||||
|
||||
**Perf finishing (T8, T9, D3):**
|
||||
- T8: `LineSignalRenderer.Stroke` cache + `AxisRenderer.TextStyle` cache (16-entry cap, single-thread UI)
|
||||
- T9: `Pair<Float,Float>` removed (FloatArray out-param) + `signalsArray` cached on `RealtimeChartState` (invalidated by addSignal/removeSignal only)
|
||||
- D3: LTTB upper-bound aligned to half-open `[start, start+windowMs)` snapshot semantic
|
||||
|
||||
**Correctness (D4):**
|
||||
- D4: `NumberFormat.formatFixed` Long overflow guard @ |v|≥1e19 → routes to scientific
|
||||
|
||||
**Test gap fill:**
|
||||
- 107 → **207 tests** (+100)
|
||||
- New suites: lod/ (24 tests), interaction/ (29 tests), model/ChartConfigTest (8), render/AxisFormatterTest (10), render/AxisRendererTest (3), render/LineSignalRendererTest (2)
|
||||
|
||||
**ABI:**
|
||||
- Baseline regenerated; apiCheck GREEN
|
||||
- `chart-realtime.api`: 161 → 428 LOC
|
||||
- `chart-realtime.klib.api`: 211 → 501 LOC
|
||||
|
||||
**Deviations from plan:**
|
||||
- `iosX64` target dropped (Compose-MP 1.11.0 dropped Intel iOS sim variant)
|
||||
- `MinMaxLttb` perf 1.80× (paper claims 10× — gap = scalar Kotlin/Native vs Rust+SIMD; ≥1× acceptance met)
|
||||
- `signalsArray` cache NOT invalidated by `clear()` (entries preserved per T10 contract)
|
||||
|
||||
**Highlights vs plan goals:**
|
||||
- Interaction layer S0 shipped (was "fatale senza")
|
||||
- HARD BREAK on T2/T5 per intake decision (no deprecated bridges)
|
||||
- All v0.4.0 deferred items (D1/D3/D4) absorbed

## Risks
|
||||
- T2 (MinMaxLTTB): break LodMode enum API → migration required by consumers
|
||||
- T7 (interaction): biggest scope, multi-modal touch testing manual
|
||||
- T5 (config split): breaking API change, mitigare con typealias + deprecated factory
|
||||
- T5 (config split): breaking API change → HARD BREAK per intake decision
|
||||
- D1 (toolchain bump): Kotlin 2.1→2.3 + Compose 1.8→1.11 behavior surprises
|
||||
- BCV 0.18.1 (Jul 2022 release age): agent verifies latest at apply, fallback 0.16.3
|
||||
- AGP 9.2.0 may need Gradle wrapper bump
|

## v2 deltas (intake-confirmed 2026-05-21)
|
||||
|
||||
Source: kmp-manager intake. Applied directly by manager (mechanical scope additions, no architectural change).
|
||||
|
||||
### Decisions locked
|
||||
- **Breaking API**: HARD BREAK on T2 (`LodMode` removed) + T5 (old `ChartConfig` ctor + `targetFps` removed). No `@Deprecated` bridges. ABI baseline regen.
|
||||
- **Versioning**: stay `0.5.0-SNAPSHOT` at close. No tag. No publish.
|
||||
- **Datetime**: drop `kotlinx-datetime` entirely. Use `kotlin.time.Clock.System.now().toEpochMilliseconds()` (stable since Kotlin 2.3.0, no `@OptIn`).
|
||||
- **Toolchain**: full alignment — Kotlin 2.3.21, Compose-MP 1.11.0, AGP 9.2.0, coroutines + kotlin-test aligned, BCV verify-latest.
|
||||
|
||||
### New tasks
|
||||
|
||||
#### D1 — Toolchain bump (P0, blocks all)
|
||||
- Files:
|
||||
- `gradle/libs.versions.toml`
|
||||
- `gradle/wrapper/gradle-wrapper.properties` (if Gradle bump needed for AGP 9.2.0)
|
||||
- `chart-realtime/build.gradle.kts` (drop `kotlinx-datetime` dep)
|
||||
- `chart-realtime/src/commonMain/kotlin/dev/dtrentin/chart/RealtimeChartState.kt:16,90` (swap `kotlinx.datetime.Clock` → `kotlin.time.Clock`)
|
||||
- Goal: Kotlin 2.1.0→2.3.21, Compose-MP 1.8.0→1.11.0, AGP 8.7.3→9.2.0, coroutines 1.9.0→latest, kotlin-test→2.3.21, BCV→verify-latest (fallback 0.16.3). Drop kotlinx-datetime. Single call site swap.
|
||||
- Agent: gradle-expert
|
||||
- Verify:
|
||||
- `./gradlew :chart-realtime:compileKotlinAndroid` green
|
||||
- `./gradlew :chart-realtime:iosSimulatorArm64Test` 107 tests pass (regression gate)
|
||||
- `./gradlew :chart-realtime:apiCheck` green (no ABI delta from toolchain alone)
|
||||
- `./gradlew :chart-realtime:assembleRelease` green
|
||||
|
||||
#### D3 — LTTB upper-bound semantic fix (P5)
|
||||
- Files: `chart-realtime/src/commonMain/kotlin/dev/dtrentin/chart/buffer/LodDecimator.kt` (or post-T2 `lod/LttbLod.kt`)
|
||||
- Goal: align LTTB upper-bound with snapshot half-open `[lo, hi)` semantic. Currently inclusive → off-by-one at window boundary.
|
||||
- Agent: data-impl
|
||||
- Verify: existing 33 LodDecimator tests pass + 1 new boundary test
|
||||
|
||||
#### D4 — NumberFormat Long overflow guard (P1)
|
||||
- Files: `chart-realtime/src/commonMain/kotlin/dev/dtrentin/chart/render/NumberFormat.kt`
|
||||
- Goal: `formatFixed` Long path overflows @ |v|≥1e19. Add guard → route to `formatScientific` before overflow.
|
||||
- Agent: data-impl
|
||||
- Verify: new test `formatFixed_handlesLongOverflow` + existing 38 NumberFormat tests pass
|
||||
|
||||
### Task semantic changes
|
||||
|
||||
#### T2 (was: deprecated bridges) → HARD BREAK
|
||||
- Remove `LodMode` enum entirely (was: `ChartConfig.lodMode: LodMode` → `lodStrategy: LodStrategy`).
|
||||
- No `LodMode.MIN_MAX_LTTB` shorthand. Pure interface.
|
||||
- ABI baseline regen: `./gradlew :chart-realtime:apiDump` + commit.
|
||||
|
||||
#### T5 (was: deprecated old ctor) → HARD BREAK
|
||||
- Remove `ChartConfig` original ctor entirely. Replace with new ctor taking `DataConfig + AxisConfig + RenderConfig`.
|
||||
- Remove `targetFps: Int?` field. Replaced by `RenderConfig.frameRate: FrameRate`.
|
||||
- No `@Deprecated` bridges.
|
||||
- ABI baseline regen.
|
||||
|
||||
#### T6 — verify SignalConfig stability covered
|
||||
- Add `@Immutable` to `SignalConfig` (closes deferred v0.3.0 issue: Compose compiler unstable warning).
|
||||
|
||||
### Updated P-groups
|
||||
| Group | Tasks |
|
||||
|-------|-------|
|
||||
| P0 | D1 (toolchain, blocks all) |
|
||||
| P1 | T1, T6, T10, D4 |

|
||||
| P5 | T8, T9, D3 |
|
||||
| P6 | ABI regen + apiCheck + unify |
|
||||
|
||||
### Acceptance additions
|
||||
- A10: Kotlin 2.3.21 + Compose-MP 1.11.0 + AGP 9.2.0 green on all targets; 107 tests pass on iosSimulatorArm64.
|
||||
- A11: ABI baseline regenerated post-T2/T5; `chart-realtime.api` + `chart-realtime.klib.api` committed.
|
||||
- A12: `LodMode` symbol absent, `targetFps` symbol absent, `kotlinx-datetime` dep absent. No `@Deprecated` bridges in commonMain public API.
