Model is now pure data (categories, cells, formulas, measure_agg) with
no references to view/. The Workbook struct owns the Model together
with views and the active view name, and is responsible for cross-slice
operations (add/remove category → notify views, view management).
- New: src/workbook.rs with Workbook wrapper and cross-slice helpers
(add_category, add_label_category, remove_category, create_view,
switch_view, delete_view, normalize_view_state).
- Model: strip view state and view-touching methods. recompute_formulas
remains on Model as a primitive; the view-derived none_cats list is
gathered at each call site (App::rebuild_layout, persistence::load)
so the view dependency is explicit, not hidden behind a wrapper.
- View: add View::none_cats() helper.
- CmdContext: add workbook and view fields so commands can reach both
slices without threading Model + View through every call.
- App: rename `model` field to `workbook`.
- Persistence (save/load/format_md/parse_md/export_csv): take/return
Workbook so the on-disk format carries model + views together.
- Widgets (GridWidget, TileBar, CategoryContent, ViewContent): take
explicit &Model + &View instead of routing through Model.
Tests updated throughout to reflect the new shape. View-management
tests that previously lived on Model continue to cover the same
behaviour via a build_workbook() helper in model/types.rs. All 573
tests pass; clippy is clean.
This is Phase A of improvise-36h. Phase B will mechanically extract
crates/improvise-core/ containing model/, view/, format.rs, workbook.rs.

Disable the eval_formula method in Model. This may be a temporary change or
part of a larger refactor of formula evaluation.

Refactor formula handling to use a virtual '_Measure' category.
- Formulas now default to targeting '_Measure' if no category is specified.
- '_Measure' items are dynamically computed from existing data items and
formula targets, preventing redundant item storage.
- Updated persistence to handle '_Measure' formulas and items correctly in
Markdown.
- Updated UI and model to use 'effective_item_names' for layout and item
resolution.
- Updated tests to reflect the new '_Measure' behavior.

_Measure is now a virtual category (CategoryKind::VirtualMeasure),
created automatically in Model::new() alongside _Index and _Dim.
Formula targets are added as items automatically by add_formula.
Formula evaluation uses a fixed-point cache: recompute_formulas()
iterates evaluation of all formula cells until values stabilize,
resolving refs through the cache for formula values and raw data
aggregation for non-formula values. This fixes formulas that
reference other measures when hidden dimensions are present.
evaluate_aggregated now checks the formula cache instead of
recursively evaluating formulas, breaking the dependency between
formula evaluation and aggregation.

Model::add_formula now ensures the formula target exists as an item in
the target category (same fix as AddFormula effect, but at the model
level — covers file loading and headless paths).
Formula panel now shows raw formula text instead of debug-formatted
string with redundant target name and quotes.

Circular or self-referencing formulas now return CellValue::Error
instead of stack overflowing. eval_expr uses Result<f64, String>
internally so errors (circular refs, div/0, missing refs) propagate
immediately through the expression tree via ?. The depth limit (16)
is checked per evaluate_depth call — normal 1-2 level chains are
unaffected.
Also adds CellValue::Error variant for displaying ERR:reason in the
grid, and handles it in format, persistence, and search.

Updates `Model` to include `regular_category_names` , which returns
category names excluding virtual categories (_Index, _Dim). This allows
other parts of the application to distinguish between user-defined
categories and system-internal ones.
Co-Authored-By: fiddlerwoaroof/git-smart-commit (unsloth/gemma-4-26B-A4B-it-GGUF:UD-Q5_K_XL)
Add unit tests for model precision and category tree rendering:
- `src/model/types.rs` : Added `formula_chain_preserves_full_precision` to
ensure formulas use full `f64` precision for calculations, even when
display is rounded.
- `src/ui/cat_tree.rs` : Added comprehensive tests for `build_cat_tree` ,
covering empty models (virtual categories), expanded/collapsed states,
and item rendering.

Update TogglePanelAndFocus and related components to use open/focused flags.
Changed TogglePanelAndFocus from currently_open to open+focused flags.
Parser accepts optional [open] [focused] arguments.
Interactive mode toggles between open+focus and closed/unfocused.
Keymap updates: F/C/V in panel modes close panels when focused.
Model initialization: Virtual categories _Index/_Dim default to None
axis, regular categories auto-assign Row/Column/Page.
App test context updated with visible_rows/visible_cols.

Add new commands for enhanced data entry and category management.
AddRecordRow: Adds a new record row in records mode with empty value.
TogglePruneEmpty: Toggles pruning of empty rows/columns in pivot mode.
ToggleRecordsMode: Switches between records and pivot layout.
DeleteCategoryAtCursor: Removes a category and all its cells.
ToggleCatExpand: Expands/collapses a category in the tree.
FilterToItem: Filters to show only items matching cursor position.
Model gains remove_category() and remove_item() to delete categories
and items along with all referencing cells and formulas.

Add support for Label-kind categories to handle high-cardinality
per-row fields like descriptions, IDs, and notes. These fields are
stored alongside regular categories but default to Axis::None and
are excluded from pivot category limits.
Changes:
- analyzer.rs: Label fields now default to accepted=true
- wizard.rs: Collect and process label fields during model building,
attaching label values as coordinates for each cell
- category.rs: Add Label variant to CategoryKind enum
- types.rs: Add add_label_category() method and update category
counting to only include Regular-kind categories

Implement records mode (long-format view) when drilling into aggregated cells.
Key changes:
- DrillIntoCell now creates views with _Index on Row and _Dim on Column
- GridLayout detects records mode and builds a records list instead of
cross-product row/col items
- Added records_display() to render individual cell values in records mode
- GridWidget and CSV export updated to handle records mode rendering
- category_names() now includes virtual categories (_Index, _Dim)
- Tests updated to reflect virtual categories counting toward limits
Co-Authored-By: fiddlerwoaroof/git-smart-commit (unsloth/Qwen3.5-35B-A3B-GGUF:Q5_K_M)
Add view navigation history with back/forward stacks (bound to < and >).
Introduce CategoryKind enum to distinguish regular categories from
virtual ones (_Index, _Dim) that are synthesized at query time.
Add DrillIntoCell command that creates a drill view showing raw data
for an aggregated cell, expanding categories on Axis::None into Row
and Column axes while filtering by the cell's fixed coordinates.
Virtual categories default to Axis::None and are automatically added
to all views when the model is initialized.

Refactor DataStore to use interned keys (InternedKey) instead of
string-based CellKey for O(1) hash and compare operations.
Introduce SymbolTable-backed interning for all category and item
names, storing them as Symbol identifiers throughout the data structure.
Add secondary index mapping (category, item) pairs to sets of interned
keys, enabling efficient partial match queries without scanning all cells.
Optimize matching_values() to avoid allocating CellKey strings by
working directly with interned keys and intersecting index sets.
Update all callers to use new API: iter_cells(), matching_values(),
and internal lookup_key() helper.
