Suggested reviewers: Merge Risk: 🟡 Moderate · up to The new end-to-end flow may tap before the shared-value update is visible, causing flaky or incorrect test results. Merge readiness requires adding a reliable synchronization point before the dependent tap. 🚥 Pre-merge checks | ✅ 3✅ Passed checks (3 passed)

In @.argent/flows/shared-value-test.yaml:
- Around line 35-39: Insert a runtime-visible synchronization step after the
increment-taps-button tap and before tapping shared-value-box, so the
asynchronous numberOfTaps update is complete before the gesture tap proceeds.
Keep the existing shared-value-box and console verification flow unchanged.

Argent mobile UI testing flow YAML "await: { idle: true }" semantics
💡 Result:
In the Argent mobile UI testing framework, the await: { idle: true } directive is a synchronization mechanism used to ensure the application UI has reached a stable state before the test runner proceeds to the next step [1]. Semantics and Behavior: The await: { idle: true } directive invokes the await-screen-idle tool [2][1]. Unlike await-ui-element, which waits for a specific element to appear or change state (e.g., become visible or hidden) [3][4][5], await-screen-idle monitors the entire UI tree to ensure it has settled [2]. Key characteristics include: - Settling Condition: The framework considers the screen "idle" when the accessibility tree (or component tree) stops changing for a minimum duration (minStableMs) [2]. It achieves this by taking consecutive "snapshots" or "signatures" of the UI tree and verifying that they match over a specified period [2]. - Use Case: This directive is primarily used to prevent "timing" or "flakiness" issues where tests interact with an app while it is still transitioning, loading, or animating [2][4]. It is the preferred, deterministic alternative to using fixed delays (delayMs), as it allows the test to resume as soon as the UI is stable [3][4]. - Implementation: When idle: true is encountered in a flow, the runner blocks execution until the screen signature remains constant for the required threshold [2]. If the tree continues to change (e.g., due to ongoing animations or data loading) beyond the defined timeout, the step will fail, preventing the test from continuing in an unstable state [2]. This approach aligns with standard UI automation principles—similar to waitForIdle in Android Compose or Espresso—where the test environment synchronizes with the application's internal state to ensure reliability without relying on brittle, hard-coded sleeps [6][7][8].

Gate the gesture tap on the shared-value update.
The JavaScript handler updates numberOfTaps asynchronously, but the next step taps shared-value-box immediately. await: { idle: true } only waits for a stable accessibility tree, and this shared value does not re-render the screen. Add a runtime-visible synchronization point before tapping shared-value-box.

Pull request overview
This PR enhances the Common App “Shared Value” (new API showcase) screen to be reliably automatable, and adds a new Argent E2E flow that validates dynamic tap-gesture configuration driven by a Reanimated shared value.
Changes:
- Added indexed console logging for key tap-gesture callbacks and for the “required taps” increment action.
- Added stable
testIDs and a brief instruction blurb to support E2E automation and debugging. - Introduced a new
.argentflow that exercises the shared-value-driven tap-count behavior and asserts callback ordering/output.
