Run from inside another command, automate.stopAction rolled back that
command's own group, pulling the workbook from under the rest of its run; and
the recording buffer kept it, so a recording could replay the stop inside the
run it was part of. Nested, the command is refused and the group stays; the
recorder leaves it out (record::NOT_RECORDED).
stash::items and stash::keys listed the first 10,000 items and let the rest
vanish without a word. They return a Listing { found, more } now, so a caller
can say what it did not list.
The guard asked for a hidden name, but the stash reads a legacy _sc_<key>
name whether it is hidden or not, so a visible one could be removed or
replaced without force. stash::holds_item is the one rule (item_of), shared
by the guard; the test covers a visible legacy name.
The guard refused any name of the stash's shape, so a visible name a person
had defined, such as _gc_rate_0, could not be edited or deleted from Name
Manager, which cannot pass force. It now refuses a name only when the
workbook holds a hidden workbook-scope item under it; a visible name of the
shape is the person's own, as the stash itself treats it. The test covers
such a name. The query comment says what the copy skip relies on: a query
runs nothing that changes the history.
`Trust` defaulted to `Local`, and `DocState::new` set it, so a
document was trusted unless its maker remembered to mark it. Every
current path that reads a file goes through `file.open`, which marks
it `FromFile`, but a later way of building a document from bytes
(recovery, templates, a new import) would have come out trusted by
omission.
`DocState::new` now takes the `Trust`, and `Trust` has no default.
New workbooks and samples pass `Local`, `file.open` passes
`FromFile`, a new window passes the trust of its workbook, and the
tests that build documents from bytes pass `FromFile`.
`formulas.defineName {"name": "_gc_macro_1_0"}` replaced the hidden
chunk of a stored item with a visible name: the item vanished from
`stash::get` and `stash::keys`, and its other chunks stayed behind as
orphan hidden names. `formulas.deleteName` could remove chunks the
same way, and `formulas.createFromSelection` with `replace` could
replace one from a cell label. `stash::set` refused a clash with a
visible name, but nothing guarded the other direction.
Defining, renaming or deleting a name that `stash::item_key`
recognises (`_gc_<key>_<n>` and legacy `_sc_<key>`) is now refused
with an error that names `force: true`, which lets the call go ahead.
Create from Selection lists such labels in `skipped` unless `force`
is true. The params docs of the three commands say so.
Each `stash::get` looks at every defined name, so listing the items
with `keys` and then reading each with `get` took time quadratic in
the number of names. A file with 20,000 hidden `_gc_macro_<i>_0`
names took about ten seconds in a debug build, and the macro list
reads its items this way from data that comes from the file.
`stash::items(wb, prefix)` now groups the names by item in one pass
and returns each item's text by key, and `keys` lists from the same
pass. Both return at most `MAX_ITEMS` (10,000) items, the first keys
in sorted order, so a file with any number of hidden names can't make
a listing unbounded. A test counts the names each listing looks at.
The xlsx writer drops characters XML 1.0 can't carry: controls other
than tab, line feed and carriage return, and U+FFFE and U+FFFF. A
stash item holding one lost it on save without a warning, and so did
a JSON item, since serde_json leaves U+FFFE and U+FFFF unescaped: a
stored macro parameter changed silently.
`chunk_formulas` now writes each such character, and the marker
itself, as the noncharacter U+FDD0 followed by four hex digits, and
`get` turns them back for `_gc_` items. A marker that isn't followed
by four hex digits naming a character is read as it is. An escape
counts as five units against the 255-unit literal limit and is never
split across literals, and the guard on the stored size allows the
longest item even when every character is escaped. Legacy `_sc_`
items are read unchanged.
A command that opened an undo group and then returned an error (a `?`
between `group_begin` and `group_end`) left the group open for good:
Undo and Redo refused with "finish or stop the running action first",
later edits made no undo steps, and nothing could stop the group.
`execute` now rolls back every group a failed command opened, as
`group_rollback` does, restoring the workbook, selection, undo and
redo history to where each group began. Only a command that succeeds
keeps a group it opened, which is what a debugger's start needs.
`Session::abort_groups(doc)` and the menu-less command
`automate.stopAction` roll back the groups left open on a document,
for a debugger the person abandons or a caller that dropped its
token. The command is not undoable and works while a group is open,
and the Undo refusal now names it.
Two items under one key, in any case, would leave two hidden names of one
name, of which an xlsx file keeps one, and get would mix their chunks. A
caller's mistake, refused before anything changes. Regression test.
- Workbook::macros is a shared list (Macros, a copy-on-write newtype): a
workbook copy made for a cell edit or an undo snapshot holds the same list,
and the undo budget charges a list once a snapshot owns its own copy.
Before, every mutating command copied every step of every macro, and a
hundred undo entries kept a hundred copies the budget never saw.
- Saving to xlsx drops the last save's items and writes the macros in one
pass each (stash::set_many), instead of a scan of every name per macro.
- A hidden _gc_macro_<x>_<k> name with a key this build did not write is
kept on open and on save, as a visible one is, instead of being dropped
without a warning.
- macros::check is the one check for every path that adds a macro (JSON, a
file, built in code): the model's limits and the xlsx size limit.
Regression tests for each.
stash::keys reported a key that get read as missing, because only a later
chunk of it existed. keys now counts chunk 0 and legacy names only, as get
does. Regression assertions in the hostile-names test.
`_gc_watch_00` parsed as chunk 0, so a hidden one was read as the item's first
chunk and a visible one stopped `_gc_watch_0` from being written. Only the
chunk number as `set` writes it counts now. Regression test.
Paste Link writes a formula into every cell whatever `what` says, so a linked
paste of formats from a file now makes the destination FromFile as a paste of
formulas does. Column widths and notes write no cells, linked or not, and
still carry nothing. Regression test for the three kinds.
The check ran once per chunk, each a scan of every defined name: an item of many chunks in a workbook with thousands of names compared every pair. One pass now parses each visible workbook-scope name and refuses when it is a chunk of this key below the chunk count. The behaviour and its test are unchanged.
- #2369: its test joins the single ui-egui integration-test binary (tests/it), as main now builds them.
- #2367: a cell set to empty text is a blank entry and doesn't grow the AutoFilter (CodeRabbit).
- #2387: MOD's range check also covers the sign-corrected remainder (CodeRabbit).

- range.setValues with parse: false still turns on Wrap Text for a line break (CodeRabbit).
- Japanese: the fill-handle hint says AutoFill (オートフィル), not paint (CodeRabbit).

Home > Format as Table on a cell or range inside an existing table
failed with "A table can't overlap another table." Excel applies the
picked style to that table instead. The command now returns that table
and its range, as it does for a new table. A range crossing a table's
edge is still rejected.
Without a range, the active area of the selection decides, as it does
for Insert > Table. The native Format menu's Format as Table now runs
home.formatAsTable instead of insert.table.
- automate.trustScripts: only a missing `trusted` defaults to true; a
non-boolean value is an error and leaves the workbook untrusted.
- The refusal message points at Trust Scripts in View > Macros (Alt+F8)
and at automate.trustScripts.
- Catalog row for automate.trustScripts; parity checklist regenerated.
- Script steps run inside an io::ScriptSandbox (thread-local) so
read_file/write_file refuse whatever the parameter is called, and a
step that raises OpenUrl is dropped and stops the script. The id/param
deny list stays as the up-front refusal.

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.

Every string in `values` went through typed input, which reads it with en-US
rules, and nothing said so:
"05.04.2026" (dd.mm.yyyy) → the date 4 May 2026
"02/11/2026" (dd/mm/yyyy) → the date 11 February 2026
"2.500" (thousands) → the number 2.5
"4.25 %" (text) → 0.0425, formatted 0.00%
A workbook built from Turkish-format exports therefore held different values
than the script put in it, and the only way to notice was to read the saved
file back cell by cell.
`parse: false` stores every string as the text it is. A formula is still a
formula — `=` means a formula in a cell, and the ticket asks for that — and
numbers, booleans and null are unaffected either way. A leading apostrophe is
part of the text rather than the marker that makes it text, since nothing is
being marked.
The default is unchanged: `parse` is absent in every existing call, and those
calls behave exactly as before. A `parse` that is neither true nor false is a
usage error rather than a quiet default.
The test pins both sides — the swapped date, the decimal point and the
percentage under today's default; each of the six strings stored verbatim with
`parse: false`, with `=1+1` still calculating 2; numbers and booleans either
way; and the refused `parse` values. Without the change the first string comes
back as a date.
The item store read, listed and removed every workbook-scope name of the `_gc_<key>_<n>` shape,
visible or not, so saving an item removed a person's own visible name that happened to look like
one. Items are the hidden names the store writes; a legacy `_sc_<key>` name still reads. A visible
`_gc_` name is left alone by every operation, and writing an item that would need that name is
refused before anything changes: a hidden name beside it with the same name is the one an xlsx
file drops, so the item would be lost on save.
