The reachability gate measures what the shell's designed surface can
reach. It found 85 engine commands the engine could execute and the
shell could not. This branch closes twenty-eight of them, family by
family, without adding a single menu row. The measurement moves from
168 bound commands of 253 (66.4 %) to 196 of 253 (77.5 %); 57
remain unreachable.

The Select verbs go through the engine (decision 0104). Select All,
Deselect and Select Inverse read the editor's current cell — one
layer, one state — while CS6's dom.selectAll() covers every element
of the page in the current frame, "all elements on all layers". The
selection was also view state only: Editor::sync_selection pushes the
view's selection into the document, and the Select verbs never crossed
that bridge, so "Deselect" did not deselect the document and a later
selection-scoped command could act on a selection the user had already
emptied on screen. The three verbs now dispatch selection.selectAll,
selection.selectNone and selection.selectInverse and adopt the
document's answer. The Layers panel gains "select this layer's objects"
(selection.selectAllOnLayer).

The Pages panel renames and deletes pages (decision 0105). A row
gains a rename and a delete; the delete goes through page.delete, so
the last page of a document cannot go, and the current page index
follows the shorter list.

The Styles panel redefines and scales styles (decision 0106). Each
row gains a "redefine" (style.redefineByIndex), and the panel gains a
text-scale factor and a "Scale Styles" button (style.scaleStyles).

The States panel reorders the states and fans the selection
(decision 0107). "Move left" and "Move right" dispatch frame.reorder;
the selection gains selection.duplicateToFrames,
selection.duplicateToFrameRange and selection.distributeToFrames,
each syncing the view's selection into the document first; and the
active layer's cell in the current state gains its two flags through
cell.setVisible and cell.setLocked.

The Properties panel writes the text object's layout (decision
0108). The paragraph's indent and spacing (text.setTextParaIndent,
text.setTextParaSpacingBefore, text.setTextParaSpacingAfter), the
on-path offset (text.setTextOnPathOffset), and "Fit box to text"
(text.setTextRectangleAuto).

The Properties panel writes the text object's rendering (decision
0109). The three custom anti-alias dials
(text.setTextCustomAntiAliasSharpness,
text.setTextCustomAntiAliasStrength,
text.setTextCustomAntiAliasOverSample), the run list
(text.setTextRuns), the frame the text flows inside
(text.setTextRectangle), and the fitted box anchored at the frame's
corner (text.setTextRectangleAutoFromPoint). Decision 0108 had
recorded the anti-alias dials as unbound because the engine carries no
anti-alias preset setter; that was wrong — the three custom dials
have setters of their own — so 0108's consequence is amended.

The Pages panel lists the guides; the Layers panel moves the
selection
(decision 0110). Each guide is a row with its position and
a remove button (page.changeGuide, page.removeGuide), and a layer
row gains "move the selection here" (object.moveToCell).

The twenty-eight commands: selection.selectAll, selection.selectNone,
selection.selectInverse, selection.selectAllOnLayer,
selection.duplicateToFrames, selection.duplicateToFrameRange,
selection.distributeToFrames, page.setName, page.delete,
style.redefineByIndex, style.scaleStyles, frame.reorder,
cell.setVisible, cell.setLocked, text.setTextParaIndent,
text.setTextParaSpacingBefore, text.setTextParaSpacingAfter,
text.setTextOnPathOffset, text.setTextRectangleAuto,
text.setTextCustomAntiAliasSharpness,
text.setTextCustomAntiAliasStrength,
text.setTextCustomAntiAliasOverSample, text.setTextRuns,
text.setTextRectangle, text.setTextRectangleAutoFromPoint,
page.changeGuide, page.removeGuide, object.moveToCell.

The reachability floor is not re-pinned by this branch, on purpose:
the floor is a one-way ratchet, and re-pinning it here would raise it
above the value the other open branches measure. It is re-pinned on
main after this branch lands, together with the docs/GAPS.md §16
measurement.

Local gate: cargo fmt -p app -- --check is clean. The full
cargo run -p xtask -- ci could not run locally — the host's Cargo
admission is closed while the CI runner compiles — so the CI receipts
are the gate for this branch.

The Select menu's three verbs never reached the engine: Select All and
Select Inverse read the editor's current cell (the active layer's cell
in the current state) and copied its ids into the view's selection,
while Deselect emptied the view and left the document's selection
where the last bridged command had put it.

CS6's dom.selectAll() covers every element of the page in the current
frame, across layers. The shell covered one layer, so Select Inverse
complemented a smaller set than CS6 does.

The three verbs now dispatch selection.selectAll, selection.selectNone
and selection.selectInverse and adopt the document's answer as the
view's selection; Select Inverse syncs the view's selection into the
document first, the idiom Select Parents already uses. The Layers panel
gains "select this layer's objects" (selection.selectAllOnLayer). A
deselect with nothing selected sends no command, so no undo step
records a change that did not happen.

Decision 0104.

Co-Authored-By: Claude Code <noreply@anthropic.com>
The Pages panel listed the document's pages and let the user click one
to make it current. The engine has carried page.setName and
page.delete all along, but nothing in the shell reached them: a
multi-page document accumulated unnamed pages that could not be
removed from inside the application.

The panel now carries a rename (an inline name field, Enter applies —
the shape the Layers panel already uses) and a delete per row. The
delete goes through page.delete, so the engine's refusal stands (the
last page cannot go) and undo carries the page back; the current page
index follows the shorter list.

Decision 0105.

Co-Authored-By: Claude Code <noreply@anthropic.com>
The Styles panel could apply a style and import a library, and
nothing else. The engine has carried style.redefineByIndex and
style.scaleStyles since the start — the CS6 DOM verbs
redefineStyleByIndex and scaleStyles — and the shell could reach
neither.

Each style row now carries a "redefine" button that captures the
selection's appearance into that style through style.redefineByIndex,
and the panel carries a "text scale" factor with a "Scale Styles"
button that dispatches style.scaleStyles, which multiplies every
library entry's text size. The engine's refusals stand: a
non-positive factor is refused, and scaling an empty library is a
no-op.

Two more engine commands become reachable from the shell's designed
surface.

…tion

The States panel could add, duplicate and delete a state, set its
delay and turn onion-skinning on. It could not move a state, and it
could not put the selection onto the page's other states.

"Move left" and "Move right" now dispatch frame.reorder for the
current state. The selection gains three fans: selection.duplicateToFrames
("next", "all"), selection.duplicateToFrameRange (the "from"/"to" row)
and selection.distributeToFrames. Every fan syncs the view's selection
into the document first, the same bridge the Select menu's verbs use.
The active layer's cell in the current state gains its two flags
through cell.setVisible and cell.setLocked.

Six more engine commands become reachable from the shell's designed
surface.

Walkthrough

The pull request expands shell panels with controls for selection, timeline, pages, layers, styles, text, symbols, filters, and masks. It also updates master-page rendering, shared-layer display defaults, and image-mask coverage handling.

Changes: Shell panels and rendering

Layer / File(s) Summary
Selection and state timeline
crates/app/src/shell/mod.rs, crates/app/src/shell/timeline.rs, docs/decisions/0104-the-shells-selection-verbs-go-through-the-engine.md, docs/decisions/0107-the-states-panel-reorders-and-fans-the-selection.md, docs/TASKS.md
Selection actions now use engine commands and synchronize document and view selections. The States panel adds state reordering, selection copying and distribution, and cell visibility and lock controls.
Pages, guides, and shared layers
crates/app/src/shell/panels.rs, crates/compose/src/render.rs, crates/compose/tests/master_page_render.rs, crates/doc/src/fwmap/reader.rs, crates/doc/src/fwmap/tests.rs, crates/engine/src/catalog/layer.rs, crates/engine/src/catalog/page.rs, crates/app/src/shell/mod.rs, docs/decisions/0105-the-pages-panel-renames-and-deletes-pages.md, docs/decisions/0110-the-guides-and-the-layer-move-reach-the-engine.md, docs/decisions/0115-the-pages-panel-marks-the-master-and-the-layers-panel-shares.md
The Pages and Layers panels add page, guide, master-page, selection-movement, and shared-layer controls. Rendering draws master-page layers before the requested page. Shared-layer links and new master layers are created with display enabled; the reader defaults shared links to display enabled.
Style and text properties
crates/app/src/shell/panels.rs, crates/app/src/shell/mod.rs, docs/decisions/0106-the-styles-panel-redefines-and-scales-styles.md, docs/decisions/0108-the-properties-panel-writes-the-text-layout.md, docs/decisions/0109-the-text-properties-write-the-rendering-dials.md
The Styles and Properties panels add style redefinition and scaling, text layout and rendering controls, text-run editing, and text-frame sizing. Shell tests cover page, style, text, guide, and layer operations.
Symbol and button properties
crates/app/src/shell/panels.rs, crates/app/src/shell/mod.rs, docs/decisions/0111-the-symbol-panel-carries-the-symbol-family.md, docs/decisions/0112-the-markup-verbs-and-the-button-text.md
Symbol properties add button, animation, instance-data, definition-content, and alias-duplication controls. Text markup and button-text controls dispatch their corresponding engine commands.
Filter and mask properties
crates/app/src/shell/panels.rs, crates/app/src/shell/mod.rs, crates/engine/src/catalog/mask.rs, docs/decisions/0113-the-filters-panel-bakes-and-renames.md, docs/decisions/0114-the-properties-panel-carries-the-mask.md
The Properties panel adds filter renaming and bake operations, plus mask inspection and controls. Mask coverage and image-to-path conversion now read assembled RGBA data; tests cover matte-mask coverage and conversion.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: Critical · previous review cd394

The desktop and web app do not build as submitted because a helper method is defined twice. Once that is fixed, many of the new panel text fields still discard what the user types. Deleting an earlier page jumps the view to the wrong page. Master-page rendering can lose zoom scaling and draw shared layers twice. Crafted mask files can crash mask operations. This should not merge until these are fixed.

Explanation

The title "feat(shell): close the measured reachability gap in the shell's panels" is specific and matches the main change. The PR wires previously unreachable engine commands into the shell's panels (selection, pages, styles, states, text, symbols, filters, masks, and shared layers), so the title describes the primary work. The title is somewhat broad, since the changes span many panels, and the PR description's 28-command scope differs from the larger set in the commit messages. That breadth does not make the title misleading.

The text properties showed characters, font, size and the style
flags, and nothing of the layout. A text box in FireCraft behaved as
a fixed rectangle: no paragraph indent, no space above or below a
paragraph, and no way to tighten the frame around the text.

The panel now carries the paragraph's indent, spacing before and
spacing after, each read from the object's text style and written
through text.setTextParaIndent, text.setTextParaSpacingBefore and
text.setTextParaSpacingAfter. A text item on a path carries its
offset through text.setTextOnPathOffset, and "Fit box to text"
dispatches text.setTextRectangleAuto — CS6's smallest box around the
text. The two selection-scoped setters sync the view's selection into
the document first, the same bridge the Select menu's verbs use.

Five more engine commands become reachable from the shell's designed
surface.

The board's refresh rule asks for the same change that lands the
work. The reachability campaign's row names the branch, the five
decision records and the fourteen commands the branch binds.

Co-Authored-By: Claude Code <noreply@anthropic.com>
The reachability gate measured the engine commands the shell's
designed surface could not reach. This batch binds nine more of
them, with no menu row added.

The Properties panel gains the text object's rendering: the three
custom anti-alias dials (sharpness, strength, oversampling), the
run list, the frame the text flows inside, and the fitted box
anchored at the frame's corner (decisions 0109). Decision 0108 had
recorded the anti-alias dials as unbound because the engine carries
no anti-alias preset setter; that was wrong — the three custom
dials have setters of their own — so 0108's consequence is amended.

The Pages panel lists the page's guides, each movable and
removable, and the Layers panel moves the selection onto another
layer (decision 0110).

The symbol instance's panel grows four sections, each owning one
part of the family the reachability gate measured as unreachable:
the button's four behavior flags and its three export options, the
animation span's six writes, the instance's parameters and custom
data, and the definition's own contents (lift an object out, or move
it within the symbol's z-order). "Duplicate for alias" gets its
door too.

Sixteen commands, all through the engine's registry. The animation
verbs and the alias duplicate read the document's selection, so the
panel syncs the view's selection first — decision 0104's bridge.

Local cargo is closed on this host (the CI runner compiles here),
so the gate is the GitForge receipt.

Decision 0111 records the four new panel sections and the sixteen
engine commands they bind. The live board now reads 212 bound
commands of 253 (83.8 %), up from 168 (66.4 %) on main.

Co-Authored-By: Claude Code <noreply@anthropic.com>
CS6's Format menu restyles the runs, not the base style; the text
panel now carries those four markup verbs and their inverses. The
button section carries CS6's two button-text replacement verbs, one
across the library and one across the definitions the selected
instances reference.

Six commands, all through the engine's registry.

Co-Authored-By: Claude Code <noreply@anthropic.com>
Decision 0112 records the markup section and the two button-text
verbs. The live board now reads 218 bound commands of 253 (86.2 %).

Co-Authored-By: Claude Code <noreply@anthropic.com>
CS6's setEffectName renames an applied filter, and the bake family
applies a filter to the selection and bakes it into the pixels: by
name, by catalog name, by GUID, as a raw convolution kernel, or as
a motion blur. The panel carries all of it; the bake verbs sync the
selection first, because they read the document's selection.

Six commands, all through the engine's registry.

Co-Authored-By: Claude Code <noreply@anthropic.com>
Decision 0113 records the rename row and the Bake section. The live
board now reads 224 bound commands of 253 (88.5 %).

Co-Authored-By: Claude Code <noreply@anthropic.com>
`mask.add` mints a uniform mask as a solid matte — the file's flat
color for the tile — and the engine documents that matte as the
"reveal all" mask: opaque. But `mask_gray_plane` read the mask's
pixels through `gather`, the editable-pixels view, which skips a
matte slot entirely, so the mask the user sees and the mask the
engine measured disagreed.

Two consequences, both under the newly bound mask family:

- `mask.setMode` "mask to path" found no coverage and refused on
  the very masks `mask.add` mints;
- `mask.remove` "apply" baked an all-zero coverage into the
  content — a "reveal all" mask erased the artwork it covered.

The coverage now reads through `assemble_rgba`, the renderer's
view, which is what the clipboard's own mask reader already does
(decision 0058). `gather` keeps its editable-pixels contract: a
matte still occupies its grid slot there.

Co-Authored-By: Claude Code <noreply@anthropic.com>
CS6's Modify menu moves a mask and its content separately, converts
a mask between its raster and vector forms, and shows or hides the
mask's own fill and stroke. The engine carried all four verbs and
the shell reached none of them.

The Properties panel grows a Mask section, shown only when the
selection actually carries an element mask — every mask verb
refuses on an unmasked object, so an always-present section would
only offer dead buttons. The panel asks the engine who owns the
mask rather than re-deriving the ownership rule in the shell.

The two nudges are separate rows, because the two verbs are not
interchangeable: `mask.moveBy` translates the mask and leaves the
content alone, `mask.moveContentsBy` does the reverse. The
conversion button follows the mask's kind, and the attributes
button is its own inverse.

Co-Authored-By: Claude Code <noreply@anthropic.com>
Decision 0114 records the mask section and the engine's coverage
read. The reachability measurement moves from 224 bound commands of
253 to 228 of 253 (90.1 %), and the mask family is fully bound.

The Pages panel marks the master page with a star and carries its own
layer list; the Layers panel shares the active layer with every page,
adds or removes a page's link, detaches this page's copy and
unshares. The compose walk now paints the master page's layers behind
every other page's.

Three mints — the shared links and the master layer — inherited
Layer's derive-default display flag (smart-reference display), so the
shared content and the master layers rendered nowhere; they now mint
display layers, and the reader defaults a link slot to visible.

Co-Authored-By: Claude Code <noreply@anthropic.com>
The Properties panel now edits the rectangle primitive's own source —
the corner radius in pixels and as a fraction of the short side, and
the untransformed rect the contours derive from. It carries the
bitmap's pixel mask (a full-coverage plane, a clear, and the four
nudges that slide the selection without its pixels). The Fill & Stroke
panel gains the pattern fill: an image in the document becomes the
tile the selection's fill repeats.

Five more engine commands reach the shell's designed surface — the
measurement moves from 234 bound commands of 253 to 239 (92.5 % ->
94.5 %).

Decision 0116 records the binding and one defect it surfaced: the
primitive's transform is stored and round-tripped but never composed
into the drawn contours, and the corpus evidence that would settle
where the fix belongs is not yet in hand.

Review comments at @crates/app/src/shell/panels.rs:
- Around line 2045-2078: Persist the parameter, custom-data, button-text, and
button-option input drafts as `Shell` fields instead of recreating them each
frame. Update the `name`, `kind`, `value`, `key`, `text`, `button_text`, `link`,
`alt`, and `slice_name` inputs to retain typed values until their actions run,
and apply option changes when the fields lose focus without discarding the
drafts.
- Around line 2974-2986: Keep a persistent draft buffer in Shell for the
multiline run-list field instead of rebuilding it from text.runs each frame.
Update the draft as the user edits, then commit it through set_text_runs when
the field loses focus; ensure the draft is initialized or refreshed for the
selected text without overwriting in-progress edits.
- Around line 3583-3592: Keep the rename input and filter bake controls in
persistent Shell state instead of recreating them each frame. Key the rename
value per effect and pass the edited value to rename_filter_effect; preserve
filter_bake_fields values, including the blur_type selection, across frames so
bake, convolve, and motion blur use the user’s current inputs rather than
defaults.
- Around line 366-375: Update delete_page so deleting a page before the current
page decrements editor.page, while deleting the current page preserves the
existing clamp behavior; reset editor.frame whenever deletion changes the
selected page, and leave it unchanged when the selected page is unaffected.
- Around line 243-258: Keep the page rename text in persistent Shell state
instead of recreating it from name each frame; seed the buffer when ✎ is
clicked, then use it in the TextEdit. In the rename_page flow, commit the
buffered value through page.setName and clear the rename state on Enter or focus
loss; apply the same correction to the layers_section rename flow.
- Around line 2914-2920: Remove the duplicate private `sync_document_selection`
definition from the `impl Shell` block, keeping the `pub(super)` definition so
its visibility to the `shell` module is preserved.

Review comments at @crates/compose/src/render.rs:
- Line 315: Preserve the caller’s transform around the master-layer walk in
`walk_layers`: save the current transform before rendering `base_layers` and
restore it afterward, before rendering the requested page. Do not rely on
restoring `walk.frame`; the shared rendering context must retain its original
scale even when master paths reset the transform.
- Around line 333-334: Replace the truncating `as usize` conversion of
`frame_count` in the master-state calculation with a checked conversion and an
appropriate bounded fallback before subtracting, so oversized counts cannot wrap
or underflow on wasm. Preserve the frame-clamping behavior for representable
counts, and add a regression case covering the conversion boundary.
- Line 420: Update both renderer walks in render.rs, including the walk_layers
call shown here and the corresponding scaled-renderer walk, to deduplicate
shared-layer definitions across master and requested-page traversal by shared
UID. Ensure each definition is rendered only once per page composition while
preserving rendering of non-shared layers.

Review comments at @crates/engine/src/catalog/mask.rs:
- Line 307: Validate the tile-grid bounds before the new mask operations call
assemble_rgba, including the conversion read path, so excess matte slots cannot
trigger underflow or out-of-bounds access. Reject excess slots with InvalidState
or safely clip them within assemble_rgba, preserving valid tile behavior, and
add a regression case with an excess matte slot.

Review comments at @docs/decisions/0112-the-markup-verbs-and-the-button-text.md:
- Around line 59-60: Update the mixed-format text consequence in the markup
decision to state that markup applies to the entire text object, not only a
selected part, because the panel sends an object ID without a character range
and restyle_runs edits every run. Preserve the separate consequence about
changing a button’s label from its owning panel.

Review comments at @docs/TASKS.md:
- Line 53: Reconcile the reachability figures in the P1 row using the current
`xtask reachability` output as the source of truth. Update the number of newly
bound commands and the before-and-after totals and percentage so they agree
arithmetically with that output; do not assume the existing “sixty” or “234 of
253” is correct.

The page rename field resets on every frame, so a rename never applies

let mut rename = name.clone(); runs on every frame. egui is immediate-mode, so each frame the TextEdit gets a fresh copy of the stored name. Typed characters are gone on the next frame. On the frame where Enter is pressed or focus is lost, rename == name, so page.setName is never sent. Keep the buffer in Shell state, for example rename_page: Option<(usize, String)>. Seed it when the user clicks ✎. Commit and clear it on Enter or focus loss. The existing layers_section rename uses the same pattern and has the same defect.

Deleting a page before the current one moves the view to a different page

delete_page clamps editor.page only when it is now out of range. Example: three pages, current page 1, delete page 0. editor.page stays 1, which now points at the old page 2. The panels and canvas then edit the wrong page. editor.frame is also kept, and it may not exist on the new page. Decrement the index when index < self.editor.page, and reset frame when the page changes.

Proposed fix

         let count = self.editor.document().pages.len();
-        if self.editor.page >= count {
+        if index < self.editor.page {
+            self.editor.page -= 1;
+        } else if self.editor.page >= count {
             self.editor.page = count.saturating_sub(1);
+            self.editor.frame = 0;
         }
+        self.rename_page = None;

The parameter, custom-data, button-text and button-option inputs discard typed text

Each frame recreates these buffers:

  • name, kind and value at lines 2375–2377.
  • key and text at lines 2399–2400.
  • button_text at line 2069.
  • link, alt and slice_name, re-read from the document at lines 2045–2047.

A click on "Set parameter", "Set custom data", "in library" or "in instances" runs on a later frame than the typing. At that point the buffers hold "" (or "text"), so the commands send empty values. For the option fields, lost_focus() && changed() is almost never true on the same frame, and the value is reset anyway. The helper tests pass because they call set_symbol_param and the other helpers directly. Store these drafts in Shell fields, as style_scale, fan_first and fan_last already are.

Also applies to: 2375-2415

The run-list field cannot apply an edit

Each frame rebuilds runs from text.runs. A multiline TextEdit reports changed() on the keystroke frame and lost_focus() on a later frame, so field.changed() && field.lost_focus() is practically never true. Even if it were, the buffer has already been reset to the stored runs. set_text_runs is unreachable from the UI. Keep a draft buffer in Shell and commit it on lost_focus().

Convert the master-state count without truncation on wasm.

On 32-bit wasm, a file-supplied frame_count of 4_294_967_296 truncates to zero at as usize. The subsequent states - 1 overflows when overflow checks are enabled. A count of 4_294_967_297 truncates to one and incorrectly clamps every requested frame to zero.

Use a checked conversion with a bounded fallback before subtracting. Add a regression case for the conversion boundary.

As per coding guidelines, “input-derived numbers are hostile” and “never break wasm.”

Render each shared-layer definition only once per page composition.

If a document has a master page and a shared layer, layer.setSharing inserts that layer's link on both the master page and the requested page (crates/engine/src/catalog/layer.rs, Lines 612–671). This walk renders the definition through the master link. The page walk then renders the same definition again. Neither walk deduplicates the shared UID.

A translucent shared object becomes darker, and the second draw can cover page content. Apply a shared-layer ownership rule across both walks. Apply the same correction to the scaled renderer at Line 315.

Check tile-grid bounds before using assemble_rgba.

For an 8×8 mask with two matte slots, check_editable succeeds. On the second slot, assemble_rgba calculates base_y = 128, then subtracts it from height = 8. This causes an overflow panic with overflow checks enabled, or an out-of-bounds write panic after wrapping. The previous gather path skipped both matte slots. The new conversion read on Line 1287 has the same failure. (raw.githubusercontent.com)

The document reader retains the supplied tile list without checking its length against the dimensions. Reject excess slots with InvalidState, or clip them inside assemble_rgba, before these new mask operations use it. Add a regression case with an excess matte slot. (raw.githubusercontent.com)

Validate the tile-grid bounds before the new mask operations call assemble_rgba, including the conversion read path, so excess matte slots cannot trigger underflow or out-of-bounds access.

The reachability figures in the row do not agree with each other

The row says the branch binds "sixty" of the 85 unbound commands. It also says the count moves from 168 to 234 of 253. 168 + 60 = 228, not 234, and 234 − 168 = 66. The latest commit messages report 228/253, and the PR description reports 196/253. Reconcile the number with the actual xtask reachability output before the board records it. The guideline says: "When snapshots conflict, current source, tests, and generated evidence take precedence; reconcile the docs in the same change."

The Slices panel's inspector now carries the web object's rectangle
and its background knobs, and its header can turn the selection into
a hotspot or a slice. The Styles panel can update a named style in
place, and the Properties panel can paste a channel from the
clipboard onto a bitmap.

Five more engine commands are reachable from the shell's designed
surface: the reachability measurement moves from 239 of 253 bound
commands (94.5 %) to 244 of 253 (96.4 %).

Batch L left the panels with a duplicated selection bridge, two
registry lookups that borrowed their id, a match used as a
statement, and a needless `mut` — the four compile errors the
backup CI caught on the branch.

The CI runbook now records the queue as it measures it: one online
runner with capacity four, about twelve job starts an hour, ten
jobs to a pipeline, and the `julianday` comparison the ISO
timestamps need.

The Auto Shapes gallery carried the circle-bound and line-bound
families but not the two corner-cut rectangles, so the engine's
autoshape.rect generator had no path to the shell.

Both new tools share that generator and differ only in the corner
treatment: the rounded box cuts quarter-circle arcs, the chamfered
one cuts edge-parallel handles. The panel carries the corner radius
as a knob, and the payload clamps the cut to half the shorter side.
