A linked paste writes formulas even when it pastes values, but the values exception skipped the trust update, so a Local workbook stayed Local after linking to a FromFile one. The exception now applies only to unlinked pastes.
GridCraft keeps workbook data in hidden defined names so it travels
inside the xlsx file. The existing items write one name holding one
string literal, which past Excel's 255-character literal and
8,192-character formula limits gives a file Excel does not accept.
cmd/stash.rs stores an item `key` as hidden workbook-scope names
_gc_<key>_0, _gc_<key>_1, ..., each a formula of string literals of at
most 255 characters (UTF-16 units, as Excel counts them) joined with &,
at most 8,192 characters per name. Reading concatenates the chunks in
order and stops at a gap; it also accepts the older single _sc_<key>
name. Names are matched case-insensitively and only at workbook scope.
Keys are limited to letters, digits, _ and ., items to 4,194,304
characters, and junk around or inside the literals, duplicate or
out-of-order chunks, non-JSON and over-deep JSON all read safely.
keys(prefix) lists the stored items that start with a prefix.
Custom views, scripts, the watch list and scenarios keep their current
storage; nothing reads or writes the new names yet.
docs/architecture.md describes the engine building blocks added in this
series: undo groups, the recording buffer, document trust and this
storage.
Active content such as macros must not run only because a workbook was
opened. DocState gets a trust state: Local for workbooks made in the
session (new workbooks and samples) and FromFile for anything opened
with file.open. Active content in a FromFile workbook asks before it
runs. A second window on a workbook shares its trust.
The clipboard carries the trust of its source document. Pasting
formulas, formats (conditional formats hold formulas) or validation
from a FromFile workbook into another workbook makes that workbook
FromFile too; pasting values, column widths or notes carries nothing
active and changes nothing. Sheet moves and copies stay inside one
workbook, so its trust is unchanged. document.inspect reports the trust.
A macro recorder needs more than a journal index: the journal is
trimmed past 10,000 entries, it also holds the commands that other
commands run (so playback would run them twice), and it keeps no
selection, which relative references need.
Session now tracks how deeply execute calls are nested. While recording,
a buffer (record.rs) keeps each successful, journaled top-level call with
the document uid, the active sheet (index and name) and the selection it
ran in, then its id and parameters without secrets, as the journal
stores them. Queries, failed commands and the command that starts
recording are not kept. The buffer holds up to 100,000 steps and counts
any it drops. Session::start_recording, stop_recording, is_recording and
depth are the interface.
Automate › Record Actions keeps recording through the journal as before.
Session::grouped(label, f) runs f as one undo step on the active
document. On success the group leaves exactly one undo entry holding the
workbook from before the group; on error it restores the workbook,
selection, undo and redo stacks as they were and returns the error.
group_begin, group_end and group_rollback do the same across separate
calls, for an action that runs one step per call.
While a group is open on a document, undoable commands on it add no
undo steps of their own, so a long group neither grows the history nor
pushes older entries past the undo limit, and Undo and Redo are
disabled there. Groups nest: the outermost one makes the step, and a
failing inner group rolls back only its own changes. Closing a document
drops its groups, and a command that panics drops the groups it opened.
history.list reports whether a group is open.
Insert Copied Cells folds its nested steps into one undo step by
counting revisions; inside a group the nested steps push no entries, so
it now leaves the history alone there instead of removing entries from
before the group.
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.
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.
