Chart sheets (a sheet that holds one chart; Move Chart > New sheet, F11) were
skipped on open, and their chart sheet, drawing, chart, style and colour parts
were dropped with them because the pass-through treats those kinds as content
GridCraft rewrites. Saving a workbook lost every chart sheet.
They are now kept as they were: the <sheet> entry (name, visibility and its
place among the worksheets), the chartsheet part and everything behind it,
byte for byte, written back in place. The workbook's other sheet positions
(active tab, print areas, scoped names) are computed with the chart sheets
counted. A chart sheet is left out on save when the chart is no longer
valid for the workbook: a sheet it plots was deleted or renamed, or a
worksheet took its name.
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.
Fixes#324

- 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).

buttons, charts/pictures/shapes), in-cell editor with point mode, reference colouring,
autocomplete and argument hints, sheet tabs, status bar, dialogs, control channel
- apps/sheetcraft: desktop app (control server, file dialogs, prefs, drag & drop)
- chart: toolkit-free chart layout/rendering for 25 chart kinds + sparklines + rasteriser
- mcp + sheetcraft-cli: MCP server (headless or bridged) and CLI (info/convert/eval/cat/run/mcp)
- xtask (ci/layers/assets/wasm/version/parity), release workflows, packaging, placeholder icon
- automatic row heights
