 ## 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`).                                                       |
+| Disclosure hold        | LegendList's `maintainVisibleContentPosition`, restoring only the held row.               |
+| User scroll            | The finger. The controller detaches at drag start.                                        |
+| 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.
+
+**Removed anchor (iOS).** A hold removes the end pin in the same mount that opens the tapped
+disclosure, and React Native 0.86 on iOS moves the offset by the removed view's frame. The iOS
+subclass keeps the offset. Android keeps a removed view's last frame, so it keeps the offset already.
+React Native 0.88 skips the adjustment for a removed anchor
+([PR #57294](https://github.com/react/react-native/pull/57294)).
+
+**End pin during a drag.** Both subclasses recognize the pin by its native ID, `paseo-end-pin`,
+and skip its correction while the user drags ([user scroll](#user-scroll)). This one has no React
+Native counterpart; it stays while the timeline uses the pin.
+
+Remove the content clamp and removed-anchor overrides once the installed React Native includes
+their fixes.

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. The hit region is not the painted area: a filled toolbar control such as the composer's send or stop keeps the 44pt frame and paints a 36pt disc inside it (`TOOLBAR_DISC_SIZE`), so it does not outweigh its unpainted neighbours. `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.

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.

+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.

On macOS, the Explorer toggle occupies a fixed top-right window slot so opening and closing Explorer does not move the pointer target.
 
+Each window edge has one safe-area owner. `WindowLayoutProvider` publishes the bottom inset that every surface reads through `useSafeAreaInsets()`: on iOS 27.1 and later it is UIKit's bottom-bar clearance, which refines the rectangular home-indicator inset to the screen's corners, and elsewhere the system inset. Surfaces apply that value once and never stack their own spacing under it; `WindowLayoutSurface` owns the horizontal insets the same way.

 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.

+## Contribute composer items
+
+`addComposerItem` mounts a plugin component in the agent, draft and New workspace composers. The
+public contract is the [composer items reference](../public-docs/plugins/reference.md#composer-items).
+
+A plugin reads one `ComposerModel` (`packages/app/src/composer/model.ts`): state, subscribe and
+commands. `toPluginComposer` (`packages/app/src/plugins/composer-items/`) turns its state into the
+`PluginComposer` an item reads, and the host never learns which kind of composer it got. Two
+implementations provide it:
+
+- A running agent's `agentComposer(serverId, agentId)` (`composer/agent-composer/`). It exists
+  without a mounted tab: the prompt and attachments are the agent's draft in the draft store, the
+  settings are the session store's agent, and `model` and `thinking` resolve through the provider
+  catalog with `resolveAgentModelSelection`, the picker's own function, so a read equals what the
+  picker shows. The model loads the catalog itself and resolves with no models until it lands, as the picker does,
+  so a read never differs from what the picker shows. While anything watches the model it holds a
+  `QueryObserver` on the agent's catalog: that is what lets reconnect repair, which refetches only
+  active queries, refresh a catalog nobody has a picker open for, and retry one that failed.
+  `PluginComposersSource.subscribe(selector, listener)` is what holds it for `useComposers`, so
+  the subscription must go through the model's own `subscribe`. Watching again after the catalog
+  was invalidated or failed refetches it, and a read with no watcher starts one deduplicated
+  refresh and shows the cached catalog until it lands. The model keeps one pair of store
+  subscriptions however many components watch it. It is shared for as long as its agent is in the
+  session and not archived, so a command a plugin saved keeps reaching the composer a later tab
+  mounts; it is dropped when the agent is gone or archived and nothing watches it or has one
+  mounted, checked on session changes and when the last holder lets go. The mounted
+  `AgentControls` plugs its input in with `attachInput` so `insertText` lands at the cursor.
+  Without a live input the model writes the stored prompt with `replaceDraftText`, which also asks
+  a mounted input to show it. A workspace the user left stays mounted, display none. Web
+  drops the input ref there; native keeps the input, with a stale cursor and selection.
+  `ComposerInput.isLive()` is how the model tells: it needs the ref and a retained panel that is
+  showing (`useRetainedPanelActive`). Closing a root agent's tab archives
+  it, so a running agent with no mounted composer at all only exists as a subagent whose tab was
+  closed. The daemon does not check `setModel` and `setThinking` against a catalog; the provider
+  decides and its refusal rejects the call.
+- A draft or New workspace screen's `composerModelFromHalves`, an adapter over the two contexts
+  in `composer/session.tsx`: `Composer` provides `ComposerInput` (prompt, attachments),
+  `DraftAgentControls` provides `ComposerAgent` (settings), and the adapter enforces the lock.
+
+`ComposerAgent` stays for the built-in controls. Add a capability to the `ComposerModel`, both
+implementations and `toPluginComposer`; never branch on `context` in the host.
+
+`useComposers` and `composers()` reach an agent's model by reference (`plugins/composer-items/source.ts`):
+`PluginInstallationProvider` provides the plugin's source to every surface, and
+`createPluginCapabilities` puts `composers` on every command context. `{ focused: true }` is the
+agent Command Center registration hands to agent items, published through `plugins/focused-agent.ts`
+(null outside a workspace route). The source reads that module, not the navigation or layout
+stores, so the plugin runtime does not import them. The remembered workspace selection is
+navigation restore state and is not the focused agent. The query-cache subscriptions react to
+`updated` events only: a `useQuery` in another component's render announces `added`, and a
+subscriber that updates then triggers React's "update a component while rendering a different one"
+warning.
+
+Plugin `Toggle`, `Select` and `Action`, the thinking select and provider option controls all
+render through `ComposerControl` (`packages/app/src/composer/agent-controls/composer-control.tsx`),
+a toolbar icon or a row in the overflow sheet. Model and mode stay specialized but share its trigger,
+density and overflow. Plugin items count in the density presence in `layout.ts`, so a composer
+condenses to make room for them. A custom component renders wherever its item is placed, and an
+item that renders nothing still counts for density; there is no registration for either.
+
+A command runs against the owner's current state, not the render that built the callback. The
+draft's form (`openAgentForm`) and options (`openDraftOptions`) are plain stores for that reason,
+and `draftComposerAgent` rejects a provider the host does not offer. It passes a model id to the form
+as the picker does, with no catalog check; for a running agent the provider decides. `ComposerControl` owns the pending state and the error toast for callbacks that
+return a promise.
+
+The overflow sheet's content portals to the app root, away from the composer. Pass
+`useComposerSheetBridge()` as the sheet's `contextBridge`, or `useComposer()` returns nothing and
+the sheet draws no plugin rows.
+
+## Contribute New workspace items
+
+`addNewWorkspaceItem` mounts a plugin component on the New workspace screen. The public contract
+is the [New workspace items reference](../public-docs/plugins/reference.md#new-workspace-items).
+
+The screen's choices that a plugin may change live in one plain store,
+`createNewWorkspaceSetup` (`packages/app/src/screens/new-workspace/setup-model.ts`): the base
+picker selection, the manual isolation, the branch name and the workspace metadata. The pickers and
+the plugin commands write to it, so a command sees what an earlier command left. Project and host
+stay in the screen's hooks (`useNewWorkspaceHostSelector` reconciles them against each other), and
+they are read-only to plugins; a command that switched them would unmount the item that called it.
+
+The store is built in the render that creates the screen, with what the screen derives from its
+hooks (the lock, the project, whether the project can make worktrees, whether the host supports
+metadata), so a command is valid from a child's first effect, which runs before the screen's own
+effects. `syncInputs` refreshes those inputs in a layout effect on every commit, and commands read
+them when they run, never from the render that built them. The pickers and the commands pick
+through the same `chooseBase` and `chooseIsolation`, so a plugin command has the effects of a
+pick; the screen injects those effects when it builds the store (syncing the picker's PR attachment,
+remembering the isolation), so a command from a mount effect does the same as a click. Closing the
+picker stays in the picker's own handler. Add a capability by extending the store;
+do not read screen state from a plugin component.
+
+The item host (`PluginNewWorkspaceItems`) keys the items by `(serverId, project id)`, so a change of
+project or host remounts them. That is what keeps an item's own state and a `Combobox`'s cached
+results from outliving their project: the `Combobox` cannot tell that an author's inline `search`
+now means another project, because its identity changes every render. The store clears `branch`
+and `metadata` on the same change in `syncInputs`, and a remounted item's mount effect sets them
+again.
+
+An item's commands come from `setup.commandsFor({ serverId, projectId })`, bound to the target the
+item was mounted for. Once `syncInputs` reports another target they reject with a "moved" error, so
+a lookup that finishes after a project switch cannot write into the new project's choices. The
+reset only clears what was already written; this check covers what is written later. Rejecting, not
+ignoring, matches the lock: a command's promise resolves only when the change took effect.
+
+Known limit: an item that issues a command from `useLayoutEffect` on mount after a project or host
+switch runs before the screen's `syncInputs` layout effect, so its commands (bound to the new
+target) still see the previous target and reject as moved. This applies to a project switch as well as a host switch, since items
+remount per `(serverId, project id)`. Passive effects are not affected.
+
+`ensureWorkspace` sends the store's `branch` as `source.branchName` whenever the worktree cuts a
+new branch (`startsNewBranch`, which mirrors the daemon: anything but a checkout, including no base
+at all on a detached HEAD), and its `metadata` on `workspace.create` when it is not empty. The
+server uses `branchName ?? worktreeSlug` as the new branch. `baseRef.name` is the exact ref
+creation uses; `branchNameFromRef` is for labels only.
+
+Items render through `ComposerControl` with `surface="field"`: a `FieldTrigger` (a badge on
+desktop, a full-width field when compact) and the same pending state, error toast and list as the
+composer's controls. `ComposerControlLockProvider` carries the screen's lock to them. Plugin
+`Combobox` is a `select` item with `remoteSearch`: the app `Combobox` does not filter locally, and
+`PluginCombobox` (`plugins/react-native/composer-controls.tsx`) runs `search` through
+`useFetchQuery` with `dataShape: "list"`, which keeps the previous results while a newer query runs.
+`plugins/item-host.tsx` is the host shared by composer and New workspace items.

+/**
+ * React Native's scroll view with three maintainVisibleContentPosition corrections.
+ *
+ * An anchor removed by the mount it anchors. React Native picks the anchor before the mount and
+ * moves the offset by the anchor's movement after it. When the mount removes that view, its frame
+ * after the mount no longer describes the content, and the offset jumps by an unrelated amount.
+ * Android keeps a removed view's last frame, so it keeps the offset. This class keeps the offset on
+ * iOS too.
+ * The chat timeline hits this when it stops following its end: the same mount removes the end pin
+ * and opens the disclosure the reader tapped.
+ * React Native 0.88 skips the adjustment for a removed anchor
+ * (https://github.com/react/react-native/pull/57294). Its view-registry tag check matches the check
+ * here; its superview check also skips anchors that removeClippedSubviews detached
+ * (https://github.com/react/react-native/issues/58910). Remove this part once the installed React
+ * Native includes the tag check.
+ *
+ * The chat timeline's end pin during a drag. While the timeline follows its end, a zero-height view
+ * at the bottom of the content (native ID "paseo-end-pin", packages/app/src/agent-stream/
+ * native-end-pin.tsx) is the anchor, so every line that mounts scrolls the content by its height.
+ * A drag owns the offset from the frame it begins, and JS removes the pin only a round trip later.
+ * While the user drags, a mount anchored on the pin keeps the offset, so the line grows below the
+ * rows under the finger. Android's PaseoScrollView does the same.
+ *
+ * A shrink at the end. A mount that shrinks the content sets the smaller contentSize, and UIKit
+ * clamps contentOffset to the new end. React Native then adds the anchor's movement to the clamped
+ * offset, so the shrink is applied twice and the viewport lands above the content it kept.
+ * The chat timeline hits this when a finished turn folds while the end pin follows the latest row.
+ * https://github.com/react/react-native/issues/58578
+ * Remove once https://github.com/react/react-native/pull/58695 ships; it keeps the pre-mount
+ * offset and clamps after the adjustment, as this class does.
