 7. **[`core`]** **[`structural_renderer`]** Added the `pack_err_structural!`, `pack_structural!`, and `group_structural!` macros for creating types that support structured output (JSON/YAML/TOML/RON). These are like `pack_err!`, `pack!`, and `group!` respectively, but also mark the type with the `StructuralData` trait, enabling the `StructuralRenderer` to serialize them.
 
 8. **[`core`]** **[`structural_renderer`]** Added the `StructuralData` derive macro and sealed trait, decoupling structured output from `Groupped`. Previously, under the `structural_renderer` feature, all `pack!` and `pack_err!` types automatically derived `Serialize`. Now, structured output is an opt-in property controlled by `StructuralData`:
-  - `pack!` / `pack_err!` / `group!` no longer derive `Serialize` even when `structural_renderer` is enabled.
-  - To enable structured output, use `pack_structural!` / `pack_err_structural!` / `group_structural!` or the `#[derive(StructuralData)]` marker.
-  - The `Groupped` trait no longer requires `Serialize` bounds, and `AnyOutput::new` no longer requires `Serialize`.
-  - `StructuralRenderer::render` now accepts `T: StructuralData + Send` instead of `T: Serialize + Send`, and the individual format methods (`render_to_json`, etc.) are now private.

 9. **[`core`]** **[`structural_renderer`]** Added `mingling::__private::StructuralDataSealed` and `mingling::__private::StructuralData` (re-exported from `mingling_core::renderer::structural::structural_data`) to support the sealed trait pattern. The `StructuralData` trait is only implementable via the derive macro or the `_structural` macro variants.

 11. **[`mingling`]** Added four new resource types for directory environments:
 
-   - `ResCurrentDir` — Wraps `std::env::current_dir()` as a global resource. Provides `new() -> Result`, `Default` (panics on failure), and conversions from/to `PathBuf`, `&Path`, and `&PathBuf`.
-   - `ResCurrentExe` — Wraps `std::env::current_exe()` as a global resource. Provides `new() -> Result`, `Default` (panics on failure), and conversions from/to `PathBuf`, `&Path`, and `&PathBuf`.
