home.insertRows {"rows":"3"} and home.insertColumns {"cols":"B"}
failed with "not a range": only spans such as 3:3 or B:B parsed. The
same went for deleting, hiding, sizing and grouping rows and columns.
A single row number or column letter now means that one line.
- Action::Pending now consults the engine catalog at fire time: silent
no-op while the command is missing, runs it once it exists - no table
edit needed when a future feature lands.
- Stripped stray backticks from 7 pending target ids so catalog lookup
can ever match them.
- gridcraft-engine: doc(hidden) register_test_command hook so UI tests
can prove the go-live path without touching production code.
- Tests: pending_sequences_are_silent_no_ops (no dialog/toast/journal),
pending_sequences_go_live_when_the_command_lands (fake command fires
via its reserved sequence), every_sequence_terminates_without_panicking
(all 413 sequences pressed end-to-end).

Protect Sheet and Unprotect Sheet were journaled with their `password`
param, so the password showed in plain text in the journal dialog and
`engine.journal`, and a recorded script (Automate > Record Actions)
saved it in the workbook's hidden `_sc_scripts` name.
Session::execute now journals the params without secret ones
(`password`, or a name ending in `Password`). A replayed entry runs
without that param: Protect Sheet protects with the same options but no
password, and the matching Unprotect Sheet still succeeds.

data.solver maximises, minimises or targets a value in an objective cell by
changing variable cells under <=, >=, =, int and bin constraints. Simplex LP
linearises the model through recalculation, checks linearity and solves it
with a two-phase simplex; integers use branch and bound. The GRG Nonlinear
choice runs an augmented-Lagrangian projected-gradient method. The model is
saved as hidden solver_* names; Solver Parameters and Solver Results dialogs.

New sheet before the active one with the sorted history, a FORECAST.ETS
forecast column, FORECAST.ETS.CONFINT lower/upper bounds, an optional
FORECAST.ETS.STAT table, an Excel table over the data and a line or column
chart. Parameters: timeline/values (default: the selection's first two
columns), end or periods, confidence interval, seasonality, missing-point
fill, duplicate aggregation, statistics, chart kind. Data ribbon button
opens a form dialog; programmatic calls never do. gridcraft-functions
exports Timeline to continue a timeline (numeric step or calendar months).

data.analysisToolPak runs Descriptive Statistics, Histogram, Correlation,
Covariance, Regression, Moving Average, Exponential Smoothing, Rank and
Percentile, the three t-Tests, F-Test and Anova: Single Factor, writing a
static report to an output range or a new sheet. Non-empty output cells are
refused unless overwrite is set; the dialog asks instead.

- 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).

cell_param returned None for any cell argument it could not parse, so every
command that falls back to the selection (cell.set, view.freezePanes,
formulas.trace*, insert.* and others) silently used the active cell instead:
set_cell with cell "ZZZZ0" wrote A1 and reported success. It also dropped a
sheet prefix, so "Other!B2" was applied to the active sheet.
cell_param now returns Result<Option<CellRef>>. An absent or null value is still
None, so the selection fallback is unchanged; an unparsable or non-string value
is an error; a sheet prefix naming a sheet other than the one the command works
on is an error.
cell_param_on is for the commands that resolve their own sheet (cell.get, links,
comments, notes, checkboxes, chart placement, paste): they accept a prefix naming
that sheet. cell.set resolves its own target sheet and still writes to another
existing sheet.
Implements the two slicer commands from the parity catalog as first-class
floating objects that filter a table column.
- model: Slicer struct on Sheet (#[serde(default)]), included in
Workbook::next_object_id; slicer anchors use AnchorMode::MoveOnly.
- engine: cmd/slicer.rs with insert.slicer, table.insertSlicer, slicer.toggle
(single + multi), slicer.selectAll, slicer.clear, slicer.delete. Selection is
written as a FilterCriterion::Values into the sheet AutoFilter and applied via
the existing apply_filter. object.move / object.delete handle "slicer".
- ui-egui: slicers rendered, hit-tested, selected and dragged like charts; value
tiles toggle on click (Ctrl/Cmd = multi), funnel button clears. Ribbon buttons
under Insert > Filters and Table Design > Tools.
- tests: slicer_filters_table; the every_command_survives_empty_params fuzz
covers the new commands.
Native-only for now; .xlsx slicer-cache round-trip is a follow-up.

Editing a table's header cell changed only the cell: the column kept its
old name, so =SUM(Table1[a]) still worked after the header read "zz",
and saving wrote the old names back into the header row, undoing the
edit on reopening. As in Excel, the column now takes the new header;
an emptied header becomes ColumnN and a repeated one gets a number
("a2"), written back into the cell, and structured references follow
the new name.
Every edit goes through cmd::commit, which read std::time::Instant::now()
up front for GRIDCRAFT_PROFILE timing, whether profiling was on or not.
wasm32-unknown-unknown has no clock: Instant::now panics there, and with
panic=abort the browser reports `RuntimeError: unreachable`. So in the
web app, typing 1 into A1 and pressing Enter trapped (#118). The native
apps and the CLI have a clock and were unaffected.
commit now reads the clock only when GRIDCRAFT_PROFILE is set, and
never on wasm. The other clock reads (NOW(), the current year for typed
dates, the UI's frame timer) already skip wasm.
Native tests can't see this trap, so clippy.toml now disallows
Instant::now and SystemTime::now. A clock read has to be gated off wasm
and allowed at the call, and `cargo clippy -D warnings` fails on the old
commit code. The existing, already-gated reads and the native-only perf
example allow it.
Checked by building the engine for wasm32-unknown-unknown into a small
cdylib that runs cell.set A1=1 on a new workbook, and running it in
Node: before the fix it traps with `RuntimeError: unreachable`, after
it returns normally.

Only cell.set checked protection. The check now runs where every edit
is committed: an edit that changes the value or formula of a locked
cell on a protected sheet is refused with Excel's message, whichever
command made it (clear, paste, fills, setValues, replace, goal seek,
sort, insert/delete cells...).
Inserting and deleting rows and columns follow the protection's
options, and deleted lines must not hold locked cells.
Excel anchors a floating object to the grid in one of three ways, stored in the
file as the drawing anchor's `editAs`: "move and size with cells" (twoCellAnchor,
the default), "move but don't size with cells" (oneCellAnchor / editAs="oneCell")
and "don't move or size with cells" (editAs="absolute"). GridCraft had no such
concept: xlsx import dropped `editAs`, export always wrote a plain twoCellAnchor,
and sorting/filtering never moved an object — so pictures stayed put when their
rows were reordered.
Model: add `AnchorMode` on `Anchor` (serde default = MoveAndSize, so existing
documents round-trip unchanged).
xlsx: read the anchor kind and `editAs` into the mode; write it back out
(editAs="oneCell"/"absolute" as Excel does).
Engine: sorting now moves objects anchored inside the sorted body with their
lines, re-fitting "move and size" objects, keeping "move but don't size"
objects' size, and leaving absolute ones pinned. Structural insert/delete
honours the same rule (previously it moved every object's cell unconditionally
and ignored shapes). New `object.setAnchorMode` command sets an object's mode;
`arrange.selectionPane` reports it.
Tests: sort moves images with their rows; absolute objects stay put across a
sort and a row delete; move-only keeps its size; the mode survives an xlsx
round-trip; the drawing fixture parses all three anchor kinds.
