Extract helpers from auto_sum (selection and single-cell guess), update_cursor
(drag, hover, freeze, and header-edge cursors) and read_styles (dxf reader).
No behaviour change.
* Sonar: explicit imports, fn paths for closures, extract helpers for cognitive complexity
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
* Fix imports
* Fix serde imports
* Fix engine imports
* Fix clippy gate and a type error from the explicit-import change
Remove the unused imports the review flagged (cf.rs, pivot.rs, tables.rs, cmd/sheet.rs) so clippy -D warnings passes, and point the backstage parent-folder lookup at Path::to_str, which the fn-path rewrite had broken.

* Apply rustfmt to the explicit-import cleanup so the fmt gate passes
* Share the per-directory font path expansion in theme.rs
The candidate font lists repeated the same loop over the Linux font
directories in every role. A single helper expands them in the same order,
so the lookup order is unchanged and the duplicated blocks go away.

* Read the Windows fonts folder in one place in theme.rs
Every script-font list repeated the same WINDIR lookup. A single helper
returns the same path, so the duplicated lines go away without changing
which font files are tried.

* Build the light and dark UI palettes from one table in theme.rs
Tokens::light() and Tokens::dark() listed the same 40 colour fields in the
same order, so every change had to be made twice. A single palette
constructor takes the mode and picks each colour's value, so each field is
written once and both modes keep their exact colours.

* Share the Noto CJK font list between the CJK script lists in theme.rs
The Japanese, Simplified and Korean lists each repeated the same loop over
the Linux CJK directories with a different locale file name. One helper
builds that loop, and each list keeps its own face index, so the lookup
order is unchanged.

* Share Linux Noto directory list across Thai and Hebrew font lookups
Removes the duplicated directory arrays flagged by SonarCloud new-code duplication.
* Reuse in_dirs for Thai and Hebrew Noto font candidates
Removes the remaining duplicated per-directory loops flagged by SonarCloud.
* Share one font-list builder for the Thai and Hebrew faces
The two per-script functions repeated the same Windows, macOS, Linux and
variable-font setup. A single script_fonts helper now builds both lists,
keeping the candidate order unchanged, which clears the Sonar duplication gate.

Insert > Line or Area and the All Charts list offer 100% Stacked Area,
and insert.chart and chart.set take it as type area with subtype
stacked100. Each series' area stacks on the ones before it as its
share of the category's total. When every series on the value axis is
100% stacked and no value is negative, the axis runs from 0% to 100%.
A blank cell counts as zero, and a category whose total is zero stays
on the baseline.
An XLSX area chart with percentStacked grouping now opens as 100%
stacked and is saved back as percentStacked. It used to open as a
stacked area and was saved as stacked.
The writer numbers sheetIds from 1 in sheet order, so a rewritten workbook
changes the id of any sheet that is not part of a gapless series from 1.
Anything that recognises a sheet by its id (parts carried through as they
are, external tools) loses it. The model keeps the sheetId it read
(Sheet::file_id, PreservedSheet::sheet_id, not serialised to JSON) and the
writer writes it back; a new sheet, or a copy with a taken id, gets the first
free one.
Data > Outline > Settings now has Summary rows below detail and Summary
columns to right of detail. With one cleared, each group's - / + button
sits on the line before the group, its bracket runs down to the last
detail line, and Hide Detail, Show Detail, the level buttons and
Ungroup mark or clear the collapsed flag on that line. Changing a
direction moves the flags of collapsed groups to their new summary
lines.
- model: Sheet::summary_below and summary_right (on by default, also
for older JSON).
- xlsx: read and written as sheetPr/outlinePr summaryBelow and
summaryRight; files that set them no longer lose them on save.
- engine: data.outlineSettings {sheet?, summaryBelow?, summaryRight?},
undoable; outline::groups_with places the summary line.
- ui: a Settings button in the Data tab's Outline group opens the
dialog; the outline band follows the setting.
A PivotTable has an Enable show details option, set with the new
pivot.options command ({pivot?, enableShowDetails?: bool}). While it is
off, pivot.showDetails and double-clicking a value cell list no records:
the double-click shows a message and does not open the cell for editing.
Labels and headers still edit. Changing the option is one undo step and
does not refresh the report. pivot.fields reports the setting.
XLSX files keep it: an off option is written as enableDrill="0" on the
pivotTableDefinition, and enableDrill is read on open (on when absent).
Agile decryption checked only the password verifier, which authenticates
the key — not the package. An attacker who could replace EncryptedPackage
ciphertext could change workbook content undetected ([MS-OFFCRYPTO]
2.3.4.14, the descriptor's dataIntegrity element).
The reader now requires the dataIntegrity pair, decrypts it with the
recovered package key, and checks HMAC(hash, hmacKey) over the whole
EncryptedPackage stream (StreamSize field included) against the stored
value before any plaintext is returned. Excel always writes the element
("SHOULD" in the spec); descriptors without it are refused as damaged
rather than accepted unauthenticated.
- crypto: RFC 2104/4231 HMAC test vectors, RFC-test cases for a key
longer than the block size
- fixtures write the pair like Excel; new tests: missing/empty/ragged
integrity fields, tampered ciphertext and descriptor, a changed
StreamSize field
Security-sweep findings from the scan at revision ac8da7d4 (storytold-
gridcraft-agent-findings.json), no longer exploitable on main at 72c1d57d.
Each change caps work or storage per sheet/part so a hostile file cannot buy
unbounded work with ordinary bytes; each has a regression test:
- finding 2 (package.rs): a part rejected by the MAX_PART size gate is
charged its declared compressed size up front, so a loop of oversized
parts still ends the allowance instead of re-entering the package.
- finding 4 (xml.rs): elements past the kept-node cap are consumed and
dropped instead of kept — parse cost stays linear, memory stops growing
with the same input (a small compressed workbook previously asked for
gigabytes of declared-sized metadata tree).
- finding 10 (records.rs): .remaining() caches the suffix of a shared
string's Continue parts, so crossing N Continue records is O(N) instead
of O(N^2) in records scanned per character.
- finding 9 (xls shared formulas): the SHRFMLA master template is parsed
once and re-emitted per dependent cell instead of decoded and reprinted
for every referencing cell.
- findings 3, 6, 8 (sheet_read.rs): hyperlink-cell expansion, conditional-
format kept range cells and dynamic-array (deleted-spill) checks are
capped with one import warning each instead of the compact-workbook
multi-gigabyte allocation or the scanned-per-cell cost.
- finding 31 (core/parse.rs): datetime recognition no longer reparses a
prefix at every space with a time-shaped tail; an all-digit field length
is gated before the derivation machinery runs, staying linear in the
text.

builtin_id already wrote the currency formats 5-8 as custom formats
because readers resolve those ids by locale. The accounting formats
with a currency, 42 and 44, are resolved the same way but were written
as bare ids, so LibreOffice showed a 44 cell holding -0.14 as "- 0.14"
where US Excel shows "$ (0.14)". Treat them like 5-8.
- The workbook's active sheet is an atomic set in place (Workbook::active_sheet /
set_active_sheet), so a window swap or sheet switch never clones the
Arc<Workbook> or marks it dirty. Selections already live in DocState and the
window views. Save records the sheet of the most recently active window.
- A dialog taken out of its window while it runs goes back to that window when
a command run from it switched windows (dialogs::show, ui.dialog.confirm).
- view.arrangeAll {arrange?: tiled|horizontal|vertical|cascade, activeWorkbook?}
returns the visible windows, active first; the desktop moves and sizes the
native windows over the main window's monitor. New Window and Arrange All
buttons on the View ribbon; Arrange Windows dialog.
- Docs: ui-parity, hardware-parity, gaps #20, target-app-parity, ROADMAP.
A sheet can hide its outline's level buttons and brackets while keeping
the outline (Excel's Ctrl+8, saved as showOutlineSymbols="0"). It wasn't
modelled, so such sheets showed a wide outline band Excel doesn't.
- model: Sheet::show_outline_symbols (default on, also for older JSON).
- xlsx: read and written on the sheet view.
- engine: view.showOutlineSymbols {on?} (Ctrl+8), undoable.
- ui: no outline bands while it's off.
