The waveform and Send decided "is there content" separately: Send read
the input's live text, while the waveform was gated on the draft store,
whose web write lands after paint for typing performance. Between the two
commits the toolbar showed both discs, moved the mic and context ring, or
painted a disabled Send.
MessageInput now picks voice mode, Send or stop from its live text. The
composer only says whether voice mode is on offer. The focus hint reads
the same live text, since the composer no longer rerenders when the draft
gains or loses text.
* feat(app): tighten the touch composer toolbar onto the text column
On touch, the toolbar's icon-only glyphs were 20pt muted outlines at a 1.5px
stroke in loosely spaced slots, and the row sat on a flat -6 margin, so the
attach + and the trailing control floated inside the text column. Touch now
places 44pt slots edge to edge, draws icon-only glyphs at 24pt with a 2px
foreground stroke, keeps label-paired glyphs at 20pt, and runs the context
ring at 26pt with a 3px stroke. The row overhangs into the composer padding
by each end control's ink inset (composerToolbarOverhang), so the + ink and
the trailing glyph or send/stop disc sit on the text column's edges.
Pointer sizing is unchanged.
The folded model control now drops its thinking label before the model
label truncates, and the model label truncates on a word boundary
("Ten second…") instead of leaving a space before the ellipsis. Both are
decided from measured widths. The web reports layout widths rounded to whole
pixels, so a tie counts as not fitting.
* fix(app): measure replacement model labels instead of hiding them
The folded model label and TailEllipsisText kept their measuring views mounted
when the label text changed, while discarding the cached widths. A retained
measuring node whose size does not change emits no new layout event on web or
native, so after switching to a model whose label (or a shortened prefix of it)
has the same width, the widths stayed unknown and the label stayed transparent.
Keying each measurer by what it measures remounts it, so every width is
measured again.
Also move the label width sweep into a named helper so the test body states
the expected label order.
* feat(app): space the touch composer toolbar by what it paints
- Lay each control out at its painted width, 20pt apart, with a disc-sized circle that is both its frame and its fully rounded pressed highlight. Pickers are 36pt pills.
- Match the header icons: 20pt glyphs at 1.5px, an 18pt context ring at 2px.
- Always end the row in a disc (voice mode, send or stop) so it does not shift, nested into the composer's corner, with a concentric 26pt corner radius on touch.
- Stop the picker row's clip from flattening the picker highlight's left edge.
- Budget the density ladder on laid-out widths.
* fix(app): disable the stand-in send disc and keep form model fields in their box
- An empty new chat's stand-in Send is disabled until there is content, as in fullscreen.
- A custom model selector trigger, such as the schedule form's field, drops the toolbar slot's margins.
* feat(app): size controls for touch on any touch device, not just compact layouts
One gate picks touch or pointer sizing: touch when the layout is compact or
the device has a touch screen. The touch fact is read once, so attaching a
mouse or keyboard to a tablet never shrinks its controls. Stylesheets take
`bySizing({ touch, pointer })`, which resolves to a breakpoint value, so the
existing `{ xs, md }` consumers follow the gate without call-site changes.
Touch values follow the iOS HIG 44pt hit region: controls, icon buttons,
rows, bars and menu rows are 44 on touch; `sm` controls are 32. Glyphs move
to a touch ladder (14/18/20/24). Pointer sizes are unchanged.
Merges duplicated header control heights, density's private icon ladder and
the compact-only icon button sizes into control-geometry.
* feat(app): size the composer for touch through control geometry
The composer toolbar, attach / dictation / realtime / send buttons, context
meter and model triggers take TOOLBAR_CONTROL_SIZES (28 pointer, 44 touch)
instead of private 28 constants. The density budget, button glyphs and the
fullscreen glyph rail offset resolve the same gate, replacing the isWeb /
isNative glyph branches. Track rows join the menu row height.
Desktop geometry is unchanged. On touch the toolbar steps down density
earlier: iPad portrait goes from condensed to tight.
* feat(app): fold composer controls before the model label truncates
The composer toolbar walks one width budget: full, condensed, tight,
compact, then icon-only. Tight keeps the model at its family label;
below that, thinking, mode and features fold into the model control's
sheet (the phone toolbar), and only then does the model drop its label.
A touch iPad in portrait with an attachment now reads
"GPT-6-Astra Medium" instead of "GP…".
The context meter glyph and combobox rows and icons take the density
ladder. Desktop is pixel-identical in the content area.
* refactor(app): keep the sizing gate free of the theme
constants/layout sized its bars through control-geometry, which loads the
theme and runs Platform.select at import. The gate (resolveControlSizing,
bySizing, TOUCH_TARGET) moves to control-sizing.ts with no theme import;
control-geometry re-exports it, so its callers are unchanged.
* test(app): expect touch sizing in the compact Changes and plugin sidebar specs
The compact Changes options button is a 44pt icon button with a 20pt glyph,
and its framed actions trigger is 32 tall. In the compact sidebar the nav
block is capped at half the height, so 44pt rows put the plugin header row
below the cap; the spec scrolls it into view as a user would.
* fix(app): close composer menus when the controls fold or unfold
Folding swaps the toolbar controls for the model sheet. A menu opened on the
separate controls stayed marked open across the fold, so widening the
composer again reopened Thinking without a click.
* fix(app): prevent and recover workspace layout crash loops
* fix(desktop): capture resized browser tabs without hanging
A resident guest can paint fresh pixels after resize while capturePage's
native surface-copy request remains pending. The same failed guest returns
a fresh frame through frame subscription, so waiting for resize or another
animation frame does not correct the failing copy request.
Capture one subscribed frame within the existing five-second budget and
release the subscription on completion or cancellation. Preserve temporary
frame production and its original throttling policy. Remove viewport copy
retries and E2E screenshot polling; assert the resized image dimensions.
Refs #4866. Three full real-Electron browser journeys passed under Xvfb,
including physical clicks and fresh screenshots while the window is hidden.
* test(app): choose Agent before exercising the runtime catalog
The newly merged catalog journey assumed an empty workspace opened an agent draft tab. This branch opens the New launcher, so create the agent draft tab explicitly before checking its composer and model choices.
* fix: settle closed browser captures and validate persisted layout fixtures
Destroying a guest during frame subscription left its screenshot pending until the capture deadline and blocked queued captures. Reject at destruction, remove the listener on every exit, and return browser_tab_closed. The regression proves immediate settlement and queue release.
Reuse the unchanged persisted layout schema from a UI-independent module so the recovery fixture validates storage before editing it.
* test(app): encapsulate Explorer layout setup and cleanup
Keep persisted layout schemas and corrupted-state construction inside the seedCorruptedWorkspaceLayout helper. Use the existing withWorkspace fixture for cleanup in all four Explorer journeys so test bodies follow a straight setup, action and assertion flow.
* test(app): target the selected workspace in layout recovery
The corruption helper selected the first persisted entry, so a multi-workspace journey could leave the intended workspace untouched. Resolve its exact persistence key from the requested workspace ID and fail setup when absent. The failing-first journey now preserves an earlier workspace with an agent draft tab while recovering the selected workspace.
Retained tabs stay mounted under display:none while inactive, which
reports a zero-width onLayout. ControlledAgentControls fed that
straight into its density resolver, so a hidden tab's toolbar
collapsed to its tightest density and painted one frame collapsed
before re-expanding when the tab became visible again.
Extract the zero-width guard that useContainerWidthBelow already had
into a shared readMeasuredWidth helper, and use it in the composer
toolbar's own layout handler so a display:none measurement can never
drive its density.
Also bump the chat outline rail's MIN_PANEL_WIDTH breakpoint (818 ->
918) so the rail disappears earlier under a narrower panel, and widen
the chat-outline e2e spec's viewport so its panel keeps healthy margin
over the new threshold.
