 ## [Unreleased]
 
+### Changed
+- `pyproject.toml`: corrected `authors` field to `t0kubetsu` (consistent
+  with all other platform modules).
+- `reporter`: exposes a public `console` alias (`Console(record=True)`) and
+  a `save_report(path)` function supporting `.txt`, `.svg`, and `.html`
+  extensions (unknown extensions fall back to plain text).
+- CLI migrated to use `reporter.console`; `print_report()` now renders to
+  the module-level console so `save_report()` captures the output correctly.
+  The private `_save_report()` helper in `cli.py` has been removed.
