Templates hide grouped columns as width="0" hidden="1". Show Detail and the level buttons only cleared hidden, so the columns stayed invisible; they now reset a zero size, as Unhide does.
The symbol was interpolated with Rust's Debug formatting, which escapes a
control character into literal `\n`-style text. It is now written into the
format's quoted literal directly, and a symbol holding a control character is
refused along with a quote or a backslash, so nothing is escaped behind the
user's back.
Test: `accounting_format_takes_the_symbol_it_is_given` covers `\n` and a tab.
`cargo xtask ci`: 8/8 steps, 0 failures.
`home.accounting` documents `{range?, symbol?}` but ignored the symbol: the
command always applied the `$` format, so a script or MCP client asking for
lempiras (#1893) or any other currency silently got dollars. The symbol is now
part of the code it writes, and a symbol that would break the format string (a
quote or a backslash) is refused instead of being pasted in. The default is
unchanged, character for character.
Tests: `accounting_format_takes_the_symbol_it_is_given` (displayed text for `L`
and the default, and the two refused symbols) and
`the_default_symbol_reproduces_the_accounting_format` (the built code still
equals the named `Accounting` format). `cargo xtask ci`: 8/8 steps, 0 failures.
range.fill parsed the input once at the active cell, then put back the old
style of every target that already held a cell, so 5%, $5, 3/4/2026 or
=DATE(...) lost their automatic format there (0.05, 5, 46085), and empty
targets took the active cell's style. Each target now gets what
input_to_cell gives for it (parsed once per distinct style), as typing does.

Undo stored the selection at the moment of undoing (wherever the user had
clicked) in the redo entry, so redo jumped back there instead of to the
cells it changed. The redo entry now keeps the undone step's selection.

file.open takes {csvAsText: true}: a CSV, TSV or TXT file opens with every field as the text
it holds, with no number, date or boolean conversion, so identifiers such as GTINs, SKUs and
ZIP codes keep their digits and leading zeros and save back unchanged. The default is
unchanged. The CsvOptions.parse_values switch already existed in the reader.

The grid's look() and print's cell_look() layered a rule's fill, font and
borders onto the cell style but not its num_fmt, so a cell under a rule with a
number format kept its own. Take the rule's code when it isn't General (in a
differential style General means "not set", as layer_under treats it).
Print also re-formatted every non-General cell from its own style through
display::cell_text; format with the look's code instead, through a new
display::value_text_as that value_text now calls (CSV/Text output unchanged).
Show Formulas keeps cell_text.

forecast_grid re-added every squared residual in each window, O(n×window).
Keep a running sum instead: add the entering term, subtract the leaving one,
and restart at a point without a forecast so windows touching it stay #N/A.

auto_row_height estimated a line of a bigger font by scaling the sheet's
default row height by size / 11. When the sheet's default already fits
that font, the font counted twice: Excel for Mac saves rows of 16pt text
with defaultRowHeight="21" (28px) and no ht, and opening such a file
fitted every row to 40.7px, 1.45 times Excel's height. Rows mixing Middle
and Bottom aligned cells then looked misaligned.
The estimate now scales an 11pt row's height (DEFAULT_ROW_HEIGHT), so
those rows open at 29px, and rows on a 15pt-default sheet still grow to
their font (#833).

Checked black-box in Excel for Windows (Microsoft 365) with synthetic
workbooks: a bare name in <c:f> draws the whole chart blank, without a
repair prompt, for workbook- and sheet-scoped names alike, while
`[0]!Name` and `Sheet1!Name` plot.
- Write: a sheet-scoped name is written `Sheet!Name` (quoted when
needed) instead of bare; an already qualified name keeps its sheet;
an undefined name gets `[0]!`. A reference to an unknown sheet is
kept as written. A qualified series name is written as a strRef.
- Resolve: a series name `Sheet1!Name` is looked up on that sheet, as
the evaluator does, instead of being shown as literal text.

Excel writes a workbook-scoped defined name in a chart reference as
`[0]!Name`. The reader kept that text, the lexer took `[0]` for a
structured reference, and the series evaluated to #NAME?: a chart over
dynamic (OFFSET) names opened blank with one #NAME? category.
- Read: `[0]!Name` becomes `Name` in c:f (cat, val, xVal, yVal,
bubbleSize, tx), chartex cx:f and _xlchart names. External books
([1]Sheet1!...), quoted sheet names and strings are untouched.
- Write: a bare workbook-scoped name is written back as `[0]!Name`; a
sheet-scoped name stays bare. A series name that is a defined name is
written as a strRef instead of literal text.
- Resolve: a series name that is a defined name is evaluated.

Every edit copies the workbook for its undo step (copy-on-write: sheets
and 64-row bands of cells are shared). A floating picture's bytes
(Image.data) and the VBA project (Workbook.vba_project) were plain
Vec<u8>, so each edit on a sheet with a picture, and every edit in a
workbook with macros, kept another full copy of them, up to the 100
steps of the history. They are Arc<Vec<u8>> now, as cell pictures
already are, with base64 helpers for serde (b64::shared, b64::opt). JSON
and XLSX are unchanged.
Measured on macOS 27 (Apple M3 Max), gridcraft-cli, kernel peak
footprint: a 19 MB picture and 50 cell edits on its sheet, 992 -> 22 MB;
10 edits, 215 -> 21 MB.

do_sort moved cells, formulas, cell pictures, row heights and floating
object anchors through the sort permutation, and remove_duplicates moved
cells and pictures through the compaction, but neither touched
Sheet::comments or Sheet::hyperlinks (keyed by CellRef): a note that
described one record stayed behind and annotated whatever landed on that
row — 'late payment' on a paid invoice — and a note on a row removed by
Remove Duplicates annotated blank cells. Sheet::comments/hyperlinks are
exactly the range-scoped side data that row and column inserts already
remap and edit.clear already clears, so the omission looks unintended.
Both maps now travel through the same permutation the cells use (the
sort collects before re-inserting, so a swap cannot resurrect an entry
from a destination that is also a source; Remove Duplicates compacts the
kept rows and drops the rest).
Regression test: sort_and_remove_duplicates_move_the_rows_notes_and_links
— on main the note and link stay on their old cells; with the fix they
travel with their record.
A cut removed the source's cells and pictures and then re-created the
block's merged areas at the destination and copied its notes there — but
removed nothing from the source, so one merged block became two (an
empty one left behind) and a note ended up on both the old and the new
cell. Excel moves both and leaves the source clean.
The cut now clears the source range's comments, hyperlinks and merges
the same way edit.clear does. A second gap in the same path: paste never
transferred hyperlinks at all, so clearing the source would have lost
them — paste now carries hyperlinks (in What::All and a new
What::Hyperlinks, so edit.pasteSpecial {"what":"hyperlinks"} works
like "comments").
Regression test: a_cut_moves_the_sources_notes_hyperlinks_and_merges —
on main the old merge stays behind and the note is on both cells; with
the fix the merge, note and link all move and the source is clean.
print_titles read both rows and cols as Options and assigned both
unconditionally, so {"rows":"2:2"} set title_cols = None and
{"cols":"A:A"} set title_rows = None: the repeated rows or columns
disappeared from every printed page with no message, and there was no
way to set or clear just one axis. The sibling pageLayout.pageSetup
already distinguishes "key absent" from "key present but empty"; read
both axes the same way — absent leaves the axis alone, empty/null clears
it, anything else that is not a range is an error rather than a silent
wipe.
Regression test: print_titles_keeps_the_axis_it_is_not_given — on main
the rows-only call clears the columns; with the fix each axis is touched
only when named, an explicit empty value still clears, and a bad range
errors.

edit.autoFill capped source and target at 5M cells separately, but fill()
writes one cell per source lane per step, and it never checked the target
held the source. Whole rows into whole columns (`2:3` into `A:A`) filled
every one of 16,384 columns down a million rows: ~17 billion writes, then
a 24-51 GB allocation abort that catch_unwind can't stop.
Excel (observed via COM on a synthetic workbook) refuses AutoFill when the
target doesn't contain the source or holds it away from every corner, and
accepts any corner-sharing target. edit.autoFill now applies that rule
(fill::holds_source_in_corner), and fill() bounds lanes x steps by
MAX_FILL_CELLS as a backstop. The 5M literals in auto_fill and fill_dir
use the shared constant.
Regression test: fill::tests::autofill_refuses_targets_that_do_not_extend_the_source.

In Excel the "contains", "begins with" and "ends with" rules are
SEARCH/LEFT/RIGHT formulas, which fail on an error value, so an error
cell is never formatted by them and always matches "does not contain".
GridCraft matched on the error's display text instead, so #N/A
"contained" a and "began with" #.
Skip error values in the three positive rules and match them in
notContainsText, with a regression test over =NA(), =1/0 and text cells.
Prepare report data before editing so refused reports cannot leave solution cells or the saved model changed. Commit accepted reports with the optional solution and model, retaining array/protection checks and row autofit after sheet insertion.

A formula read with `cm` (Excel's XLDAPR dynamic-array record in
xl/metadata.xml) now carries `Formula::dynamic`, and the writer keeps the
`cm` and the metadata part for it even when the formula returns one value
and the export shape analysis would not need array evaluation. Before, such
formulas were saved as legacy formulas, so Excel recalculated some of them
with implicit intersection (SUMPRODUCT(IFERROR(range/range,0)) changed
value), and workbooks whose every dynamic formula was scalar lost
xl/metadata.xml altogether.
The mark survives moves, row and column insertion or deletion, sheet and
name renames and LAMBDA call-case fixes; retyping a formula drops it and
the writer decides from the formula's shape, as before. It is serialized
only when set, so saved documents without it are unchanged.
