 ## The subagents track
 
 The track is a pill at the foot of an agent's pane (`packages/app/src/subagents/track.tsx`): a count you can read at a glance, and a panel behind it — a popover on wide screens, a sheet on compact ones — holding the rows. It floats over the transcript rather than sitting in a band above the composer, so the timeline scrolls underneath it; `packages/app/src/panels/agent-tracks.tsx` owns that placement, and the pill frame is shared with the task list in `packages/app/src/composer/tracks.tsx`.

+# Agent stream disclosures
+
+Expanding or collapsing something in the chat timeline (a turn's summary line, a tool-call group,
+a tool call's inline details, a todo card) keeps the tapped trigger at the same screen y in the
+first painted frame. No animation.
+
+## The contract
+
+A disclosure component knows nothing about the list. It wraps its state change:
+
+```tsx
+const hold = useDisclosureHold();
+const handleToggle = () => hold(() => setExpanded((value) => !value));
+```
+
+`view.tsx` wraps every timeline row in `DisclosureRow`, which routes `hold` to the strategy's
+`holdRow(rowId, apply)` (`packages/app/src/agent-stream/disclosure.tsx`). Outside a timeline row,
+`apply` runs as is. The strategy owns when `apply` runs and how the row keeps its place.
+
+Following output:
+
+- A hold always detaches the bottom anchor controller (`holdForDisclosure`).
+- When the hold ends, the controller re-sticks only if the list sits at its end and no user scroll
+  owns the viewport (`releaseDisclosure({ isAtEnd })`). Expanding at the bottom therefore leaves
+  the list detached with the scroll-to-bottom pill showing; collapsing back to the end resumes
+  following.
+- Scroll events during the hold never re-stick: the correction is a programmatic scroll that
+  would otherwise read as "back at the bottom".
+
+The trigger can only stay put when the list has scroll room for the change. When the loaded
+content fits the viewport, or a collapse at the end would need an offset past the end, the list
+ends at its end and the trigger moves by the difference.
+
+## Web
+
+`holdRow` pins the row in the reading anchor and runs `apply`; the next reading reconcile restores
+the row's top after layout, before paint (`strategy-web.tsx`).
+
+## Native
+
+On compact layouts, tool calls and tool-call groups open a sheet instead of expanding, so they do
+not hold. Summary lines and todo cards expand inline.
+
+The timeline is a LegendList in forward order: one `data` array of history rows followed by the
+live head, oldest first (`strategy-native.tsx`). LegendList keeps a row in place across a size
+change in the commit that makes it, so a hold needs no anchor neighbour, native child index or
+render window stretch. The inverted FlatList it replaced needed all three, and three commits per
+toggle; its applied commit took up to 3.5 s of JS on a long turn.
+
+### Who owns the offset
+
+One owner keeps the scroll offset at any moment:
+
+| State                  | Owner                                                                                     |
+| ---------------------- | ----------------------------------------------------------------------------------------- |
+| Before rows are placed | LegendList's initial scroll to the end. It keeps the rows hidden until they are measured. |
+| Following the end      | The end pin (`native-end-pin.tsx`).                                                       |

+| Detached               | LegendList's `maintainVisibleContentPosition` on the first visible row.                   |
+| Keyboard motion        | Nobody. The keyboard translates the list with the composer and leaves the offset alone.   |
+
+The end pin is a zero-height view at the bottom of the content and the content's first native
+child, with React Native's `maintainVisibleContentPosition` set to `{ minIndexForVisible: 0 }`. The
+native correction runs on the UI thread around each mount, so a row that grows or lands at the end
+scrolls in the frame it lays out. The controller scrolls only for a viewport resize (the composer
+growing or shrinking) and an explicit jump, both through the native `scrollToEnd`.
+
+Do not use LegendList's `maintainScrollAtEnd` instead. It scrolls from JS after the mount to the end
+its JS sizes predict: growth paints below the viewport for a frame, and the scroll lands short of
+the native end, which the controller reads as the user scrolling away.
+
+The keyboard never changes the list's size, padding or offset. `KeyboardTranslateView` moves the list
+and the composer together on the UI thread, and the composer viewport clips the top of the list
+while the keyboard is open. Do not add a keyboard-sized inset to keep that content reachable: it can
+only commit after the motion, and while detached or holding nothing corrects for it, so every row
+jumps by the keyboard height after the keyboard settles.
+
+### The hold
+
+`holdRow(rowId, apply)` runs in the toggle's event:
+
+1. Mark the row held and detach the controller (`holdForDisclosure`). The pin goes away and
+   LegendList's `maintainVisibleContentPosition` takes over, restoring only the held row
+   (`shouldRestorePosition`). Upstream LegendList anchors only rows from the first fully visible
+   one down, and a size change with no data change keeps the first row in view whatever
+   `shouldRestorePosition` says. A row cut off at the top would then let the row below it hold
+   instead, moving the trigger by the row's size change. The LegendList patch counts rows cut off
+   at the top as in view and applies `shouldRestorePosition` to size changes too.
+2. Run `apply`.
+3. Call the row's `useSyncLayout` trigger. The toggle changes the row from its own state, so
+   LegendList's container does not re-render and would learn the new height from `onLayout` a task
+   later, after the change painted. The trigger puts the measurement and the corrected positions
+   in the toggle's own commit.
+
+The hold ends two frames after the last item size change, since the list measures the toggled row
+and any rows it inserted over several frames (`native-disclosure-hold.ts`). The controller then
+re-sticks only if the list is within 1 px of its end, the same distance web resumes from.
+
+### User scroll
+
+The controller detaches at `onScrollBeginDrag`, so lines that stream in during a drag grow below
+the rows under the finger. The detach reaches native a JS round trip after the drag begins, so for
+those frames the pin is still mounted. The scroll view subclasses skip the pin's correction while
+the user drags (see [scroll view corrections](#scroll-view-corrections)). They skip only the pin's:
+in the detached state LegendList uses the same native correction, and a history page that lands
+mid-drag needs it. They key on the drag, not the touch, so a tap or long press while following
+keeps following.
+
+Following resumes only for a gesture that ends within 1 px of the end, either when the finger lifts
+or when momentum stops. A release past the end counts: iOS bounces back to the end, and lines that
+land during the bounce must keep scrolling in. A release anywhere short of the end stays detached
+with the scroll-to-bottom pill, so the rows the user let go of never move.
+
+### Draw distance
+
+`drawDistance` is 2000 px on each side of the viewport. A fling over rows that were never measured
+blanks the viewport until LegendList renders and measures them. Twelve flings over a chat with a
+15,000 px turn expanded, Android emulator, dev build:
+
+| List                          | Blank viewport             | Janky frames | p50 / p90 / p99  |
+| ----------------------------- | -------------------------- | ------------ | ---------------- |
+| Inverted FlatList             | 1.3 to 1.7 s over 5 flings | 10.8%        | 27 / 48 / 109 ms |
+| LegendList, drawDistance 500  | 1.0 to 1.5 s per fling     |              |                  |
+| LegendList, drawDistance 2000 | none                       | 1.7%         | 24 / 32 / 48 ms  |
+
+With every turn collapsed, flinging from a cold open into history did not blank at any value from
+500 to 2000, and jank followed host load (19 to 40 on 16 cores) rather than draw distance. Measure
+1000 and 1500 on the expanded chat, on a host under load 10, before lowering it.
+
+### LegendList patch
+
+`patches/@legendapp+list+3.7.1.patch` carries ten changes for the timeline. Its header lists
+them by purpose, and
+[legend-list #593](https://github.com/LegendApp/legend-list/issues/593) reports each upstream.
+Drop a hunk when the installed LegendList ships its fix.
+
+### Scroll view corrections
+
+`modules/paseo-scroll` replaces React Native's scroll view on both platforms with a subclass:
+Android's `PaseoScrollView` and iOS's `PaseoScrollViewComponentView`.
+`VisibleContentPositionClampTest` covers Android; iOS has no native test harness.
+
+**Content clamp.** A mount that shrinks the content while `maintainVisibleContentPosition` is set
+applies the shrink twice on both platforms: the scroll view clamps its offset to the new end during
+the mount, and React Native then adds the anchor's movement to the clamped offset
+([RN #58578](https://github.com/react/react-native/issues/58578), fix in
+[PR #58695](https://github.com/react/react-native/pull/58695)). A turn that folds while the list
+follows its end lands above the end. Android defers the clamp to the pre-draw pass, and iOS restores
+the pre-mount offset for the adjustment and clamps after it.
+

It is 32px tall where a pointer drives it and 44px where controls are touch-sized, so every touch control meets the iOS HIG's 44pt hit region. `sm` is 28px pointer and 32px touch, with `fontSize.sm` labels, and is for tight chrome only: toolbars, nested settings rows, dense inline row actions. A `size="sm"` on an ordinary page or dialog is wrong, and so is choosing a size from `useIsCompactFormFactor()`.
 
-Buttons are pills (`borderRadius.full`) with medium-weight labels; an icon-only button is a circle. `<Switch>` follows the same two sizes: a 34×20 track by default and in `sm`, 44×26 in the compact layout, and it reserves its size's control height so a row holding one lines up with a row holding a button. Buttons, text fields, dropdown triggers, and `<SegmentedControl>` (`packages/app/src/components/ui/segmented-control.tsx`) share the size contract — the same size name means the same height and label size on every control kind, so controls in one row line up. Segments run tighter than a button, because the gap between segments already reads as padding. The selected segment is a `surface3` fill with `foreground` text, not an inverted one — inverting it inside thin chrome puts a white slab in the toolbar. A settings row sizes the controls in its trailing slot itself, default in a card and `sm` when nested (`packages/app/src/components/ui/control-size.tsx`), so don't pass a size to a button, dropdown or field placed in a row. Code that computes with a control's height outside a stylesheet uses `controlHeightForLayout`. Never shrink a control's font or padding locally to fit a context — if the context needs a smaller control, the size tier is missing or the wrong one is in use.
+Dense toolbar rows, such as the composer's, are the exception to the 44pt control. Touch-sized the row is 44pt tall and each control is a 36pt circle (`TOOLBAR_DISC_SIZE`): send and stop fill it, and every other control's pressed highlight fills it, so every highlight is the same fully rounded shape. Labelled pickers are 36pt pills. A control lays out at the width of what it paints (`toolbarSlot`, `toolbarContentSlot`) and its circle reaches into the gaps, so `TOOLBAR_CONTROL_GAP`, 20pt, is the visible space between glyphs. Toolbar glyphs match the header icons: 20pt, the app's 1.5px stroke, resting at `foreground` (`toolbarGlyphsFor`). The context ring is 18pt with a 2px stroke (`TOOLBAR_RINGS`): a circle fills its box where an outline glyph does not, and a thin circle reads lighter than a glyph at the same stroke. A disc's solid glyph, such as the stop square, stays at the `md` size (`TOOLBAR_DISC_GLYPH_SIZES`). Pointer-sized toolbars keep 28px controls, a 4px gap, and a 16pt muted glyph that brightens on hover.
+
+In the composer, the first glyph's ink starts on the text column's edge, and the trailing control is always a disc, so the row does not shift as it changes between voice mode, send and stop. The disc nests into the corner, as far from the right edge as from the bottom, and touch-sized the composer's corner radius is concentric with it (`packages/app/src/composer/input/toolbar-rails.ts`).
+
+One gate, `resolveControlSizing`, picks touch or pointer sizing: touch when the layout is compact or the device has a touch screen. An iPad with the sidebar docked is wide and touch-sized; a desktop is pointer-sized; a phone is both compact and touch. The touch-screen fact is read once at startup (`hasTouchScreen` in `hooks/use-fine-pointer.ts`), so attaching a mouse or keyboard to a tablet never shrinks its controls. Stylesheets take sizes from `bySizing({ touch, pointer })`, which resolves to a breakpoint value, so a caller never sees which sizing it got. Rows, icon buttons and icon slots take theirs from `styles/density.ts`, which uses the same gate. An `{ xs, md }` literal for a hit target or glyph is wrong: on an iPad it yields the pointer size.

+Keyboard navigation needs the sidebar's filtered workspace model even when its visual
+panel is hidden. Retain that model while keyboard navigation is active; gating it on
+panel visibility leaves number shortcuts with no targets after a compact startup.
+
+Composer send-key customization remains a separate capability. Native retains its
+existing Return submission path; advertising its web-only customization would expose
+settings the native composer does not implement.
+
+## Native sources
+
+Use the iOS window press stream for hardware keys. `UIKeyCommand` only takes keys
+that must bypass the focused text control: composer Return and the top overlay's
+Enter and arrows. Keep the stream as the sole shortcut emitter: a command-owned
+press is still observed by the window.
+
+The source spike used an iPad Pro 11-inch (M4) simulator on iOS 18.6 with a
+`UITextView` first responder. Both `UIWindow.sendEvent` and the root controller's
+`pressesBegan` received Cmd+B, Cmd+P and Escape. With Escape registered as a
+`UIKeyCommand`, the window observed it and the command handler also ran.
+
+Simulator reserves Cmd+K for Toggle Software Keyboard. Injecting it produced
+HID 184 with empty characters rather than K; plain K, Cmd+B and Cmd+P arrived
+normally. Keep Simulator input capture off: Send Keyboard Input to Device
+prevented synthetic AppleScript input from arriving, including plain text.
+For simulator QA, use Cmd+B/P to check delivery and rebind the command center to
+Cmd+J to check toggle and rebind behavior. Cmd+K delivery needs a physical iPad.
+Simulator also reserves Cmd+1…4, Cmd+Shift+A and Cmd+comma. Exercise those actions
+through rebinds. For numeric injection, use AppleScript physical key codes (for example
+25 for 9); `keystroke "9"` did not deliver a digit in the QA session.
+Simulator exposes a virtual `GCKeyboard` even with Connect Hardware Keyboard off.
+Verify the iOS absence case on a physical iPhone.
+
+Never register Backspace: it would take deletion away from text fields. Changes
+to the native module require a native rebuild; an over-the-air JavaScript update
+cannot deliver them.
+
+## Overlay ownership
+
+Register keyboard handling with `useOverlayRegistration` from `@/keyboard`.
+Pass the surface's open state, layer, handled keys and `onKeyDown`. The highest
+layer gets first refusal; the latest registration wins a tie. Native registration
+does not need a DOM ref. Web adds focus trapping and restoration through its adapter.
+
+Capture a global overlay’s layer in state for its opening lifetime. Memo caches can
+be discarded or removed by React Compiler; recomputing against the registry lets an
+open modal rise above its own children and creates competing focus traps.
+
+Declare Enter and arrow keys only while the surface owns them. Native sources
+use the top overlay's declarations to take those keys before text controls edit.
+Backspace stays with the focused input. Composition confirmation must not select
+an overlay row or submit the composer.
+
+Android modals have their own windows. Observe them through React Native's
+`ExtraWindowEventListener` as well as the activity window. The dev client bypasses
+Expo's root-container handler, so an activity root-view wrapper misses presses.
+A modal can forward an unhandled event into the activity window. Observe the event
+once across that nested delivery without retaining recycled Android `KeyEvent`s.
+Keep an overlay-owned press consumed through key-up, even if its key-down closes
+the overlay; otherwise the modal's default Escape handler can close a second layer.
+
+iOS scene startup installs the observing window after Expo creates its root view.
+Keep that integration in the hardware keyboard module's config plugin. Its window
+owns both the press stream and the text-control key commands, including above modals.
+
+## Focus scopes
+
+The composer and terminal declare focus with `useKeyboardFocusSurface`. Native
+scope derives from those declarations and command-center state. Releasing an old
+surface must not clear a newer owner's declaration during a tab switch. Web keeps
+its DOM-derived scope.
+
+Escape interrupts an agent only in the message input or an unclaimed surface.
+A focused terminal excludes that binding. The source leaves terminal Escape alone;
+terminal Escape/Ctrl forwarding is a separate feature.
+
+## Keys shared with text editing
+
+A binding on a key the platform already uses for editing, such as Cmd/Ctrl+Z for
+workspace archive undo, declares `editable: false` and registers its handler with
+`isActive` true only while it has work. An inactive handler leaves the key
+unhandled, so the pipeline skips `preventDefault` and the platform's own undo runs.

 The package patch also keeps overflowing native horizontal blocks in control of their drags: Android claims parent interception at touch-down and releases it for vertical drags so the chat list can scroll; iOS keeps its scroll recognizer active for outward drags at the leading edge. This prevents compact sidebar pans from taking block scrolling without changing sidebar swipes on prose or non-overflowing blocks. Native changes require a client rebuild.
 
+On iOS a newly mounted Markdown view paints empty for a frame or more after it is laid out at its measured height: the library parses even a view's first content on a background queue and applies it in a later main-queue turn. Expanding a turn in chat therefore shows its rows in place with the text arriving a frame later (165 ms when the mount keeps the main thread busy). Android paints the text in the first frame. Rendering a view's first content synchronously fixes the frame but costs frame time when a fling mounts history rows, so the app keeps the library's behavior until [enriched-markdown #1131](https://github.com/software-mansion/enriched-markdown/issues/1131) is resolved.
+
 Android measurements use a size-only, 512-entry LRU across view unmounts, matching the library’s existing iOS cache. Scrolling back through history can reuse layout sizes without parsing those rows again. Content, layout props and width identify each entry; font-scale changes and native layout invalidation discard affected sizes. The cache retains no views or spans.
 
 The library determines how incomplete Markdown appears during streaming. Completed text uses the same component and engine as history. Find and scroll-to-message address source message ids; selection-copy understands semantic HTML and the web code component's copy metadata.
