Protect Sheet and Unprotect Sheet were journaled with their `password`
param, so the password showed in plain text in the journal dialog and
`engine.journal`, and a recorded script (Automate > Record Actions)
saved it in the workbook's hidden `_sc_scripts` name.
Session::execute now journals the params without secret ones
(`password`, or a name ending in `Password`). A replayed entry runs
without that param: Protect Sheet protects with the same options but no
password, and the matching Unprotect Sheet still succeeds.

Czech joins Russian under "other shipped languages" in ROADMAP.md and
docs/localization-parity.md: 266 ribbon labels (~12%), menus only,
formulas still en-US. Timestamp lines and revision history updated.
Kept separate from the catalog so it can be dropped if the docs are
refreshed upstream.

View › Page Layout (and the status-bar button) now shows the sheet as printed
pages on a desk instead of overlaying page outlines on the grid.
- Model/XLSX: per-sheet view mode (normal / pageLayout / pageBreakPreview),
saved as <sheetView view="…"> and read back. view.* commands set it per
sheet ({sheet?}) without an undo step or dirtying a clean workbook.
- Engine: paper::PageGrid paginates the sheet from A1 with the print
pagination (print::split_bands, shared with PDF export and printing) and
maps cells to pages and back; header/footer section helpers
(split/join, &[Page] field names) shared with the PDF header code.
pageLayout.headerFooter takes {part, section, text} for one section and a
sheet; header/footer strings are capped at 255 characters.
view.ruler toggles the rulers.
- UI: Geo carries the page grid, so painting, hit-testing, selection,
editing, objects and scrolling work through the page transform; frozen
panes are ignored in this view. Pages with margins and gaps, "Click to add
data" pages, rulers in inches (English) or centimetres, headers/footers
drawn on printed pages, click a margin section to edit it in place; a
click elsewhere commits (one undo step), Escape cancels. Header & Footer
contextual tab: presets, Page Number, Number of Pages, Current Date/Time,
File Path, File Name, Sheet Name, Go to Header/Footer. View › Ruler.
- New strings in every catalog; new code-drawn icons; desk colour token.

Pass-through of package content GridCraft does not model: on read the raw
parts are kept with their content types and relationship graph per owner
(package root, workbook, sheet); on write they get fresh part names where
needed and new relationship ids, and the r:ids in kept XML are rewritten.
Kept: custom document properties, ribbon customisation, add-in task panes,
custom XML, links to external workbooks with <externalReferences> (never
followed), connections, sheet query tables, printer settings with the
<pageSetup r:id> (#324), form and ActiveX controls, OLE objects and sheet
backgrounds with their VML shapes (merged with GridCraft's note shapes).
Content whose graph reaches parts GridCraft rewrites is dropped with a
warning; sheet content goes with its sheet and is not copied by Copy Sheet.

Clean-room import of Excel 97-2003 workbooks from the public [MS-CFB] and
[MS-XLS] specifications: compound-file streams (FAT, mini FAT, directory
tree), the BIFF8 Workbook stream with Continue records, shared strings,
all cell records, formulas decoded from Ptg tokens (shared and array
formulas, 3-D refs, names, add-in/newer functions by name) with cached
results, number formats, the 1904 date system, merges, column widths, row
heights, defined names and print areas/titles. Encrypted (FILEPASS) and
BIFF5 files are refused with a clear message; everything else is skipped
with a warning. .xls opens as a new unsaved workbook (Save As .xlsx).

Clicking the File tab now opens a full-window Backstage view in place of the
ribbon, formula bar, grid and sheet tabs, like Excel's. Esc or the back arrow
return to the sheet. Pages: Home (new + recent), New (blank + samples), Open
(recent + Browse), Info (location, properties, Protect Workbook), Save, Save As,
Print (page preview, scope, fit to page, Page Setup), Export (PDF, CSV, web
page), Close and Options (theme, language, formula bar, AutoSave, calculation).
Every action runs an existing command or dialog.
Adds `file.options` (reports the workbook's calculation settings and asks the
interface for the Options page) and the UI command `ui.backstage {page}`.
Keyboard shortcuts and the macOS native menu are unchanged.

data.solver maximises, minimises or targets a value in an objective cell by
changing variable cells under <=, >=, =, int and bin constraints. Simplex LP
linearises the model through recalculation, checks linearity and solves it
with a two-phase simplex; integers use branch and bound. The GRG Nonlinear
choice runs an augmented-Lagrangian projected-gradient method. The model is
saved as hidden solver_* names; Solver Parameters and Solver Results dialogs.

New sheet before the active one with the sorted history, a FORECAST.ETS
forecast column, FORECAST.ETS.CONFINT lower/upper bounds, an optional
FORECAST.ETS.STAT table, an Excel table over the data and a line or column
chart. Parameters: timeline/values (default: the selection's first two
columns), end or periods, confidence interval, seasonality, missing-point
fill, duplicate aggregation, statistics, chart kind. Data ribbon button
opens a form dialog; programmatic calls never do. gridcraft-functions
exports Timeline to continue a timeline (numeric step or calendar months).

data.analysisToolPak runs Descriptive Statistics, Histogram, Correlation,
Covariance, Regression, Moving Average, Exponential Smoothing, Rank and
Percentile, the three t-Tests, F-Test and Anova: Single Factor, writing a
static report to an output range or a new sheet. Non-empty output cells are
refused unless overwrite is set; the dialog asks instead.

Audited the grid, ribbon and editor key handling against Microsoft's
published Windows and Mac shortcut lists. New keymap.rs binds the ones
whose feature already exists: Ctrl+Shift+~!@#$%^&_ number formats and
borders, Ctrl+2-5, Ctrl+Shift+: time, Ctrl+' / Ctrl+Shift+" from the cell
above, Ctrl+L, Ctrl+Shift+L, Ctrl+P, Ctrl+Alt+V, Alt+=, Alt+Down,
Alt+Page Down/Up, Ctrl+Shift+Home/End, Shift+Home, the F-key family
(Shift+F2/F3/F9/F10/F11, F5, F7, F12, Ctrl+F1/F3/F4, Alt+F1, Ctrl+Alt+F9)
and the Excel for Mac variants (Cmd+L/E alignment, Control+E Flash Fill,
Cmd+Option borders, Cmd+Shift+K/J/H/R). Number-format keys match the
physical key; AltGr text never triggers a Ctrl+Alt shortcut. Fixes the
command catalog's wrong shortcut labels and documents the audit.

The theme could only be chosen in the View tab's Display theme box, and
the app always started light. Now:
- a title-bar button switches light/dark in one click (view.darkMode);
right-click offers System / Light / Dark;
- File › Display theme offers the same three (Excel keeps it under
File › Account › Office Theme);
- the desktop app follows the system appearance until a theme is chosen
and saved in ui.json (UiState's default stays light for tests).

AAA exponential smoothing (Hyndman et al. 2008, ETS(A,A,A)) over an evenly
spaced timeline: documented seasonality, data completion and aggregation
arguments, calendar-month date timelines, autocorrelation seasonality
detection, state-space prediction intervals, statistic types 1-8.
Smoothing parameters minimise the in-sample SSE (grid + clamped
Nelder-Mead). XLSX export treats the family's range arguments as
array-taking (no spurious dynamic-array metadata), FORECAST/FORECAST.LINEAR
included.

Enumerating Vulkan adapters crashes inside Intel's igvk64.dll on some UHD
Graphics drivers, before any Rust error handling runs. Since #22 the
Windows instance is DirectX 12 only; this keeps Vulkan out of every
default path and adds two fallbacks so DX12-only can't leave a PC without
a window:
- A DirectX 12 probe before eframe starts: no hardware adapter that meets
eframe's limits -> OpenGL (plus DX12/WARP as last resort when WARP is
all DX12 offers).
- If run_native fails with a wgpu error before the app was created, start
once more with the other of DX12/GL (eframe reuses its event loop).
WGPU_BACKEND still overrides everything, and nothing else is tried then.

Sheet Right-to-Left (view.rightToLeft, XLSX rightToLeft) was stored and
round-tripped but never rendered. The grid now lays out in logical
left-to-right coordinates and mirrors on screen: painted shapes are
reflected (text and pictures only moved), floating objects move as a
whole, pointer input is mirrored back for hit-testing, Left/Right arrows
follow the screen, and the cell editor, text box editor, popups and the
vertical scrollbar are placed on the mirrored side. Page Layout gets a
Sheet Right-to-Left button.

- Model: Sheet.edit_ranges (title, ranges, optional password hash,
security descriptor) and gridcraft_model::password: the ECMA-376 legacy
16-bit hash and the salted, iterated SHA-2 hash (SHA-512/384/256; other
algorithms, damaged hashes and spin counts over 10,000,000 are refused).
New passwords use SHA-512, spin count 100000. Adds the sha2 crate.
- XLSX: <protectedRanges> read and written; an unreadable password keeps
the range locked.
- review.allowEditRanges {action: list|add|modify|delete|unlock, ...}: empty
params list; ranges can't change while the sheet is protected; unlock
verifies the password for the session. Not journaled (passwords).
- Locked-cell checks (commit guard, cell.set, picture in cell) let edits
through in open or unlocked ranges; ranges move with structural edits.
- Ribbon button and a form dialog (menu invocation only).

A value field can be a calculated field whose formula is evaluated on
the sums of the fields it names for each report cell (Excel's documented
semantics). Command to add/change/delete, dialog from the field pane,

A line chart from numeric X values (years) plotted them as a series and
there was no way to set the axis labels. Now:
- a blank top-left cell over a header row makes the first column the
category labels even when it holds numbers (the usual convention);
- chart.selectData takes categories (Horizontal (Category) Axis Labels,
"" clears) and removeSeries, and range is optional;
- Chart Design gets a Select Data button opening a Select Data Source
dialog: chart data range, legend entries with Remove, axis labels.

- Writer: one xl/threadedComments/threadedCommentN.xml per sheet with
comments (thread, replies via parentId, done for resolved, dT when known)
and xl/persons/person.xml (one person per author), with the [MS-XLSX]
relationship and content types. Each thread keeps its legacy note, linked
by the tc={id} author and xr:uid; its body is the text plus replies.
Ids are GUID-shaped and deterministic.
- Reader: keeps dT timestamps (Comment.dates, JSON-compatible), drops
replies whose thread is missing, and reads note visibility from the VML
<x:Visible/> (best effort, broken VML skipped silently).
- Invalid dates are never written. Round-trip and hostile-input tests.

The ribbon button inserted a column chart straight away. It now opens an
Insert Chart dialog: a Recommended tab (insert.chartRecommendations, a
heuristic over the data's shape: series, points, labels, negatives) and an
All Charts tab, each with a live preview of the chart for the selection.
OK inserts the chosen type and selects the chart.
insert.recommendedCharts stays dialog-free for programmatic calls: without
a type it inserts the first recommendation; type/subtype pick one.
insert_chart is split into build_chart (also used for previews).

- view.zoom100 sets the active sheet's zoom to 100% (the ribbon's 100%
button runs it).
- view.formulaBar {on?} toggles a formulaBar preference (Prefs, saved in
prefs.json on desktop; an application option, not in the file). The UI
shows the formula bar from it; the ribbon checkbox, native menu and
ui.set {formulaBar} go through the command.
- The UI-only interceptions and their entries in engine.commands are gone,
so the CLI and MCP can run both. Parity checklist regenerated (260 / 290).

UiState gains interfaceScale (percent, 100 = Auto, 75–200), saved in
ui.json and applied as egui's zoom factor on top of the desktop scale.
New UI command view.interfaceScale {percent | "auto"} clamps hostile
values; a malformed saved value reads as 100. View tab gets an
"Interface size" picker. egui's built-in keyboard zoom is turned off so the
preference owns the zoom.
