leonard_native 0.2.1

A pure-Dart Leonard contract extension that perceives and drives a native mobile app over the OS accessibility tree (via Appium/XCUITest): a stateful, self-watching extension projecting the a11y tree [...]

0.2.0

• Breaking: the iOS AppiumBackend public API is renamed to XcuiTestBackend, and its platform: constructor parameter is removed.
• Migration: replace AppiumBackend(..., platform: 'ios') with XcuiTestBackend(...).
• Breaking: VM-service methods now use the unified ext.leonard.* namespace supplied by leonard_contract.

0.1.2

• Android support: UiAutomator2Backend drives a native Android app over a local Appium server running the UiAutomator2 driver — the additive sibling of the iOS AppiumBackend. It shares the generic W3C transport (session, element find, the 4-tier resolve chain, pointer-action tap/swipe) and keeps every Android divergence inside the impl: a <hierarchy> /source parser, content-desc as the tier-1 identifier, resource-id-or-positional xpath synthesis, attribute/password-derived masking with attribute/text readback, and a press vocabulary where back is recognized and the iOS-only alert keys throw.
• New backendForPlatform(...) — the one place that maps a platform string to a NativeBackend, so the wiring is testable without a device. An unrecognized platform throws rather than silently falling back to iOS (which would parse an Android tree with the XCUITest parser and observe nothing).
• bin/leonard_native_host.dart selects through backendForPlatform, so --platform android now works; an unsupported platform is an exit-64 usage error rather than an uncaught throw.

0.1.1

• The per-node record now surfaces the OS accessibility identifier under the canonical identifier key — the same stable, locale-proof addressing key as Flutter's Semantics(identifier:) — for cross-host record parity with the Flutter semantics fragment. Previously a11yId was selector-internal and never wired to the observation.

0.1.0 — initial native host

• Initial leonard_native package: NativeExtension (a stateful, self-watching LeonardExtension) projects the OS accessibility tree into a genesis_perception fragment and exposes tap / enter_text / press / swipe tools.
• The NativeBackend seam keeps all device I/O behind a synchronous buildPerception(). AppiumBackend drives a local Appium server over W3C WebDriver against an iOS simulator (XCUITest); FakeNativeBackend is the shipped test impl.
• Standalone VM-service host runner at bin/leonard_native_host.dart.
