> [!WARNING]
> For hooks using `ctx.resolve()` or `ctx.load()`, the reported time includes waiting for other plugins, which may overestimate that plugin's actual cost.
>
> Additionally, since plugin hooks execute concurrently, the statistics represent accumulated time rather than wall-clock time. The measured duration also includes Rust-side processing overhead, Tokio async scheduling overhead, NAPI data conversion overhead, and JavaScript event loop overhead.
