OH Ark Runtime Thread Safety Audit

Use this skill to inspect, review, or fix thread-safety issues in ArkCompiler Runtime Core, especially in:

• ETS stdlib files under static_core/plugins/ets/stdlib/**/*.ets
• ETS runtime/plugin support code under static_core/plugins/ets/**
• tests under static_core/plugins/ets/tests/
• related native C++ only when an ETS API crosses the native boundary or a TSAN report points there

The common trigger is ArkTS-Sta's concurrent execution model: public stdlib APIs can be called from taskpool, EAWorker, or multiple coroutines/workers, so static mutable state and global singletons must be treated as shared across threads unless proven otherwise.

Source-Backed APIs

Use only APIs/types that can be found in this checkout or in official OpenHarmony documentation. Examples below are source-backed by this repository; treat non-exported helpers as internal implementation references, not public API recommendations.
