driving_conditions 0.5.2

Turn weather data into driving safety guidance. Road surface classification, grip estimation, visibility degradation, and Monte Carlo safety scoring. Pure Dart, no Flutter dependency.

Changelog

0.5.2

• Republish from the embedded-target Dart 3.10.1 SDK (Flutter 3.38.3) to correct a stale ^3.11.0 SDK floor in the previously-published artifact. No source or behavior change; the source already declared sdk: ^3.10.0. Restores pub get for embedded/automotive Dart consumers on Dart 3.10.x.

0.5.1 — 2026-05-10 — Refresh cascade-stale dependency constraints

• driving_weather: ^0.3.0 → ^0.4.0 (consumer-side refresh after driving_weather 0.4.0 release earlier the same day).
• fleet_hazard: ^0.3.0 → ^0.4.0.
• No source changes; pubspec dep-constraint refresh only.

0.5.0

• Dep modernization (republish cascade): bump navigation_safety_core: ^0.1.0 → ^0.10.0 (closes 9-version stale dep) + snow_rendering: ^0.1.0 → ^0.2.0 (closes 1-version stale dep). NSC dep update consumes additive surface only (no breaking changes per NSC CHANGELOG 0.2.0–0.10.0). Closes 2-month publish-debt (pub.dev last at 0.3.0 from 2026-03-15).
• New: FleetConfidenceProvider abstract interface — pluggable fleet confidence for safety simulation.
• New: ConstantFleetConfidenceProvider — explicit named replacement for the 0.8 literal.
• New: FleetHazardConfidenceAdapter — derives confidence from List<FleetReport> using road condition safety factors (dry 1.0, wet 0.7, snowy 0.4, icy 0.1).
• CpuSafetyScoreSimulationEngine, NativeSafetyScoreSimulationEngine, and SafetyScoreSimulator now accept an optional FleetConfidenceProvider. Default behaviour is unchanged (0.8 constant).
• Native simulation_run_batch C function now accepts fleet_confidence as a parameter. Shared library rebuilt.
• Adds fleet_hazard: ^0.3.0 as a dependency.

0.4.0

• Refactor: drop direct navigation_safety package dependency; consume navigation_safety_core (pure-Dart core) only. Tracks the NSC pure-Dart core extraction (commit 86632c4); driving_conditions only uses the core safety vocabulary types and never required the Flutter+BLoC surface.
• Breaking: SafetyScoreSimulator.simulate() and SafetyScoreSimulationEngine.simulate() now return SimulationResult instead of SafetyScore.
• New type: SimulationResult — wraps the mean SafetyScore with statistical measures: variance, incidentCount, and (native engine only) executionMs.
• Promoted: NativeSafetyScoreSimulationEngine is now part of the public API. Edge developers can instantiate it directly to access native-engine execution timing.
• CpuSafetyScoreSimulationEngine.simulate() now computes and exposes variance and incidentCount from the Monte Carlo runs.

0.3.0

• Harmonize package version to 0.3.0 for Sprint 80 Direction F.
• Align internal ecosystem dependency constraints to ^0.3.0 where applicable.
• No breaking API changes in this package for this release.
