Highlights

Version 0.3.0 makes device observations more explainable and gives teams better raw inputs for their own risk models—without adding an SDK-side score, verdict, network transport, persistent identifier, or permission prompt.

Better emulator and device-farm evidence

  • Expanded Android markers for Genymotion, BlueStacks, Nox, MEmu, LDPlayer, Andy, Droid4X, and KoPlayer.
  • Added Firebase Test Lab, Android test-harness, iOS simulator-environment, and XCTest markers.
  • Added structured evidence arrays and emulatorChecksPerformed, so applications can understand why a marker was observed instead of relying only on an opaque boolean.

New explainable computation signals

  • Added deriveObservationMetrics(event) for ratios, consistency checks, and probe outcome counts computed from an already-collected event.
  • Added runtime_timing observations across the JavaScript event loop, React Native bridge, and native runtime.
  • Added numeric_consistency observations for deterministic integer and floating-point calculations across JavaScript and native runtimes.
  • Extended gpu_benchmark with median, p95, median absolute deviation, coefficient of variation, and warm-up slope.

runtime_timing, numeric_consistency, and gpu_benchmark remain disabled by default. Enable them only for calibrated cohorts after representative physical-device testing.

Integrity and posture coverage

  • Expanded application provenance with Android SDK/signing and iOS receipt/build observations.
  • Strengthened OS-integrity evidence for tracing, test keys, suspicious mounts, Zygisk, executable mappings, and environment markers.
  • Added device_security_posture, the default-off transaction_safety probe, and deriveConsistencySignals().

Quality and documentation

  • Verified parity across all 19 TurboModule methods in TypeScript, Kotlin, and Objective-C++.
  • Added Android unit coverage for emulator classification and computation helpers.
  • Updated the Probe Catalog, Data Dictionary, benchmark guide, README examples, and GitHub Pages documentation.

Upgrade

npm install react-native-device-risk-signals@0.3.0

This is an additive minor release with no intentional breaking API changes. Review the new optional fields if your backend strictly validates the event schema.
