 ### Fixed
 
+- **The beta tools' faults** (item 7 in the work queue):
+  - `calculate_mass_properties` reported moments of inertia in kg·m²
+    under a kg·mm² label; the values are now kg·mm², matching the label.
+  - `pattern_circular` and `mirror_feature` reported a pattern or mirror
+    of a cut (a ring of holes) as an error; any change in volume now
+    counts, and the reply gives `volume_change`.
+  - `delete_feature` names every feature it removed, dependents included,
+    and can delete a sketch a feature uses: the features built from it go
+    with it. SolidWorks refused that delete before.
+  - `create_extrusion` and `create_revolve` use the sketch `sketch_name`
+    names (a missing name fails, listing the sketches), and
+    `create_revolve` turns about the reference axis `axis_entity` names.
+  - `create_sketch` gives the sketch the `sketch_name` you ask for. SolidWorks
+    won't rename an open sketch, so `exit_sketch` names it and replies with
+    the final name; `create_sketch` replies with SolidWorks' name and
+    `name_on_exit`.
+  - `create_part` assigns its `material`; `get_material` also reports the
+    density; `check_interference` honours `include_hidden`; `save_as`
+    keeps an existing file unless `overwrite` is on; `execute_macro` runs
+    `repeat_count` times; `sketch_tutorial_simple_hole` points at
+    `create_cut_extrude`.
+  - On SolidWorks versions without `IMassProperty`, the products of
+    inertia Ixz and Iyz were swapped.
+  - The agent guides' examples no longer send `direction: "cut"` to
+    `create_extrusion` (use `create_cut_extrude`) or a sketch line as
+    `create_revolve`'s `axis_entity`, which takes a reference axis.
+  - `create_part`, `create_assembly` and `create_drawing` say that `name`
+    is only a label: SolidWorks names a new document itself.
+  - The 23 tools these fixes cover are now `stable`, each checked by a
+    live test (`tests/live/test_live_sw_beta_tools.py`).
+  - `delete_feature` asks the agent to check with the user first, and its
+    reply carries a `warning` naming everything else it deleted (a
+    sketch takes the features built from it).
+
 - **`create_extrusion`'s reply says what was built** (#209): the end
   condition SolidWorks used (`MidPlane` for `both_directions`), and the
   thin wall. It used to echo `direction: blind`, so an agent concluded

 ### Changed
 
+- **BREAKING: inputs that did nothing are refused** (item 7). A call that
+  sends one gets an `invalid_input` error naming what to use instead:
+  - `create_extrusion.direction` (use `end_condition`) and
+    `create_revolve.direction` (use `both_directions`);
+  - `create_assembly.components` (use `insert_component`);
+  - `create_drawing.model_path` and `.sheet_format`, and
+    `create_technical_drawing`'s `template`, `sheet_size`, `sheet_format`,
+    `title`, `output_path`, `scale` and `auto_populate_views` (use
+    `generate_drawing_package`, `save_file` or `set_sheet_scale`);
+    `create_technical_drawing` takes `projection` instead;
+  - `save_file.force_save`; `options` on the five `export_*` tools;
+  - `check_interference.tolerance` and `.check_all_components`;
+  - all four `calculate_mass_properties` inputs;
+  - `execute_macro`'s `parameters`, `execution_parameters`, `target_file`,
+    `execution_mode`, `pause_on_error` and `log_execution`.
+  `add_drawing_view` refuses an `operation` other than `add`. Moments of
+  inertia from `calculate_mass_properties` are a million times larger
+  than before, because they are now in the kg·mm² their label always said.
