What

Redesigns the composer action row. Extensions and built-ins author buttons through new compound primitives — the host decides what stays inline and what collapses into one shared overflow menu.

  • New ComposerActions.{Action,ActionButton,ActionMenuItem,Inline,Leading,Trailing,Trigger} + ComposerActionsHost in @conciv/ui-kit-chat: the common case is ONE ActionButton declaration — inline it renders a tooltip icon button; collapsed, the host renders a menu item from the same data (tooltip as label, same handler, same icon). Divergent overflow rendering pairs ActionMenuItem inside an Action wrapper by nesting; Inline is inline-only content. No public ids, no dual authoring, no portals. A headless coordinator (composer-actions-core.ts, one registration cell + one width store, zero effects) does constant-slot fit arithmetic with atomic single-ResizeObserver delivery and hysteresis; the overflow menu is uncontrolled (Ark owns open state). Host regions are compound slots (Leading/Trailing/Trigger), not props. JSX tokens were tried and reverted: Solid Providers/Suspense destroy them, so registration is context-based.
  • Inline cap: the conciv composer passes maxInlineAuto={0} — only pinned (visible="always") buttons sit in the row; everything else lives behind "More composer actions", at any width.
  • All authoring surfaces migrated: built-ins (grab/new-session/compact/launch, launch's items flatten into the shared menu), whiteboard, tanstack, scaffold templates, conciv-develop + conciv-extensions skills, site docs, example app. Zero raw composer buttons remain.
  • Refresh extracted from the composer (ComposerPrimitive.Refresh and onRefresh deleted): the chat store now lives on PaneContext as a session+connection-generation-keyed memo; RefreshButton reads pane.chat() directly — panel header (chat tab only), quick per-pane bar, pip chrome. The chat websocket survives panel view-tab switches.
  • Extension-compiler fix: the node split strips Component/Surface/views from defineExtension configs — including object-method syntax and the Object.assign(extension, {…}) form the site docs teach — so single-file extensions importing UI packages no longer crash server-side extension loading.
  • Tooltip sweep: every icon-only widget button now has a hover tooltip (composer send/stop/attach, message "⋯", timeline stop, attachment chips, FAB, whiteboard chrome + pins). Send keeps type="submit" even when a tooltip slot spreads type="button" over it.
  • Extension-testkit hosts the coordinator (width-controllable); rich storybook coverage with play functions.

Design docs

docs/superpowers/specs/2026-08-16-composer-actions-collapse-design.md and docs/superpowers/plans/2026-08-16-composer-actions-collapse.md — both carry "superseded by implementation" notes; the shipped API is the one above.

Testing

TDD throughout with red-first evidence per task. New browser suites: composer-actions.browser.test.tsx (ui-kit-chat), composer-send-tooltip-slot.browser.test.tsx, composer-overflow.browser.test.tsx, quick-refresh.browser.test.tsx, panel-view-tabs.browser.test.tsx, connection-generation-remount.browser.test.tsx (app), testkit composer-actions.it.test.ts, splitter tests for both new strip forms. Post-review fixes verified: codex (2 findings), Copilot (4 real, 3 dismissed with evidence), CodeRabbit (2 real code findings + docs drift). All package gates green; storybook green; fallow pass; changeset included.

Known non-blocker: SendMessagePinsAfterEscape scroll story fails intermittently on macOS at origin/main too (green on CI) — pre-existing, tracked separately.

ComposerActionsHost takes maxInlineAuto: inline auto count becomes the
smaller of the width fit and the cap, so pinned buttons and width fit keep
their existing semantics beneath it. The conciv composer passes 0, leaving
only pinned actions in the row and everything else in the overflow menu.

The composer attachment button now goes through TooltipIconButtonSlot so it
carries a tooltip and one accessible name like every other icon button in
the row, keeping its GHOST styling.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 21a35

High risk: this PR changes composer action placement, refresh ownership, extension loading, and session handling, but unresolved issues can hide user actions, break generated extensions or server loading, misplace controls, or leave a pane attached to a disposed chat session. These correctness and runtime risks should be fixed before merging.

56-64: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider making the inline placement explicit in this fixture.

The host here uses pure width fitting at the harness default width. The production Conciv composer sets maxInlineAuto={0} per the PR objectives, so this fixture does not reproduce production placement. openMenu at line 70 clicks 'Terminal options for Claude', which requires that control to stay inline. If a future action is added to ComposerActions, the launch control can collapse into the overflow menu and this test fails with an element-not-found error that does not name the cause. Pass an explicit maxInlineAuto or an explicit pane width so the placement this test depends on is stated in the fixture.

239-244: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider a development warning when the required context is missing.

Root, Button, Inline, and DropdownItem return null when their context is undefined. An author who places ComposerActions.Root outside ComposerActionsHost, or a Button outside a Root, gets a silently empty render with no diagnostic. The file already warns for duplicate root ids, so a matching warning keeps the authoring feedback consistent. This matters for the extension authoring surface described in the PR objectives.

♻️ Example for the `Root` guard
 function Root(props: ComposerActionsRootProps): JSX.Element {
   const coordinator = useContext(CoordinatorContext)
-  if (coordinator === undefined) return null
+  if (coordinator === undefined) {
+    console.warn('ComposerActions.Root must render inside ComposerActionsHost')
+    return null

54-56: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Action slot pixel sizing is duplicated across the source and the test fixtures. ACTION_SLOT_PX = 38 in composer-actions-fit.ts, the size-8.5 classes in the primitives, and the fixture widths in the browser test all encode the same slot geometry independently. A change to any one of them breaks the others with failures that do not name the cause.

  • packages/ui-kit-chat/src/primitives/composer/composer-actions.tsx#L54-L56: add a comment on ACTION_CLASS and TRIGGER_CLASS that records the relationship to ACTION_SLOT_PX (34px button plus the 4px row gap).

Remove the obsolete asChild open item.

Line 191-193 says ComposerActions.Button needs an asChild escape. The implementation plan has settled on ComposerActions.Inline for the launch control. Close or rewrite this item so the public API does not grow for a solved case.

In `@docs/superpowers/specs/2026-08-16-composer-actions-collapse-design.md`:
- Around line 144-150: Update the RefreshButton contract to use PaneContext via
usePane() rather than useChatContext(), and specify the registered RefreshHandle
flow for invoking refresh from the panel header above ChatProvider. Remove the
conflicting direct ChatProvider requirement while preserving the
disabled-while-streaming behavior.
- Around line 80-90: Update the ownership requirement to reference
ComposerActionsHost as the component owning the coordinator and shared Menu.Root
above props.children. Revise the registration contract so Root synchronously
registers during its body using pinned and hasButton state, removing visible and
mount-time registration language while preserving the existing fields and
duplicate-id behavior.
- Around line 92-110: The fit algorithm specification must include the leading
region and both inter-region gaps in its width budget, and remove the attachment
control from the trailing-cluster description. Align the formula and observer
contract with the measured outer, leading, and trailing widths by reserving
leadingWidth, trailingWidth, 2 * REGION_GAP_PX, the trigger width, and pinned
slots before calculating visibleAutoCount; keep the specification and
implementation plan consistent.
- Around line 38-39: Update the design document’s extension import guidance and
the unresolved placement sections to consistently identify `@conciv/ui-kit-chat`
as the settled public package for ComposerActions, replacing references to
`@conciv/extension` and removing placement-as-unresolved wording.

In `@packages/extension-compiler/src/split-extension.ts`:
- Around line 60-69: Update propertyKeyName to accept non-computed ObjectMethod
nodes as well as ObjectProperty nodes, returning their identifier or
string-literal keys so isClientOnlyProperty strips matching client-only methods
and associated imports. Add a node-mode regression fixture covering method
syntax such as Component() or Surface().

In `@packages/extension/src/catalog.ts`:
- Line 108: Add the `@conciv/ui-kit-chat` dependency to the generated extension
scaffold’s manifest/configuration wherever ComposerActions is imported by the
templates, ensuring generated projects resolve the package without relying on
consumer-installed dependencies; apply the same update to both scaffold paths.

In `@packages/harness/plugins/claude/skills/conciv-extensions/SKILL.md`:
- Around line 71-82: Update the Conciv composer guidance to state that
visible="auto" actions always render in the overflow menu because maxInlineAuto
is 0; visible="always" is required for inline rendering. Clarify that priority
only orders automatic actions and does not make them inline.

In `@packages/skills/skills/conciv-develop/SKILL.md`:
- Around line 81-82: Update the ComposerActions.Button for the deploy.run action
to set its documented inline visibility to always, keeping the button in the
composer row rather than the overflow menu.

**Ownership requirement:** the coordinator context AND the shared Ark `Menu.Root` must be
_logical Solid ancestors_ (owner-tree, not merely DOM ancestors) of everything that renders
`ComposerActions.*` — the built-in actions and `<ExtensionSurface name="composer">`. Concretely:
`PaneComposer` hosts `ComposerActionsProvider` + `Menu.Root` above `props.children`. Solid
`Portal` preserves context, so extension `Menu.Item`s portaled into the shared `Menu.Content`
node resolve Ark context correctly. Items that register before the content mount node exists
(Suspense) queue and portal once it mounts.

**Registration:** each `Root` registers `{id, priority, visible, hasButton, itemCount, disabled}`
into a reactive store on mount, unregisters on cleanup. Duplicate id: dev warning, last wins.
`Root` outside a coordinator renders nothing.

Align the coordinator contract with the settled API.

Line 83 names ComposerActionsProvider, but the settled API uses ComposerActionsHost, which owns the coordinator and shared Menu.Root. Lines 88-90 also describe visible registration state and mount-time registration. The settled contract uses pinned and hasButton, with synchronous registration in the Root body. Update this section before it is used as an implementation contract.

**Fit algorithm (pure arithmetic, no DOM measurement of candidates):**

- Action buttons are uniform `TooltipIconButton` geometry, so per-slot width is a design-token
CONSTANT (`SLOT` = button width + gap) — candidate widths are never read from the DOM.
- Two passive `ResizeObserver`s (reuse `useSizeHandle`): one on the stable outer toolbar row, one
on the trailing non-collapsible cluster (attachment control, model selector, send/cancel —
model selector is the only variable-width occupant). Observers report already-computed
geometry; no forced layout reads.
- `visibleAutoCount = floor((rowWidth − trailingWidth − reservedTriggerWidth − pinnedCount·SLOT) / SLOT)`
— one subtraction and a division per resize event.
- The overflow-trigger width is ALWAYS reserved, removing the circular collapse condition
(trigger appearing forces another collapse).
- Fill: pinned (`visible="always"`) buttons always inline, then the top `visibleAutoCount` `auto`
buttons in priority-desc order; the rest collapse. Below a hard minimum budget all `auto`
buttons collapse.
- Hysteresis margin on the count boundary so drag-resizing across a threshold cannot flap
(visual stability; the arithmetic itself is negligible).
- Visibility changes never alter the observed row/cluster widths (buttons collapse into the
portaled menu, the reserved trigger slot is constant), so no observer feedback loop exists.

Correct the fit formula and observer contract.

Lines 96-100 omit the leading region and both region gaps. They also place the attachment control in the trailing cluster. The implementation plan measures outer, leading, and trailing widths and reserves leadingWidth + trailingWidth + 2 * REGION_GAP_PX + trigger + pinned slots before fitting auto slots. Keep the specification and plan identical, or narrow rows can render an auto action that does not fit.

Add a dependency contract for generated ComposerActions scaffolds.

Both templates now emit a direct import from @conciv/ui-kit-chat. The example requires a separate manifest change to resolve it. A generated extension can fail module resolution when its consumer does not already declare this package.

Make the scaffold workflow add this dependency, or return an explicit installation requirement with the generated source.

Also applies to: 175-175

…eclaration ActionButton

Replace the Root/Button/DropdownItem compound API with a headless
createActionsCoordinator (composer-actions-core.ts, zero JSX, accessor-based
registration, node-tested) plus thin components. ActionButton alone now covers
the common case: collapsed buttons render as menu items from their own data
(tooltip as label, same handler, icon reparented), so consumers declare each
action once. Divergent overflow rendering pairs ActionMenuItem inside an Action
wrapper by nesting; menu items render from registered data, no portals. Public
ids, duplicate-id dedup, itemCount tracking, and patch-sync effects are gone.

Migrated all consumers (conciv app, extensions, testkit fixture, catalog
scaffolds, example app, compiler test fixtures). Guarded harnessName on
meta.isSuccess in apps/conciv since menu labels now evaluate in the host's
Suspense boundary.

175-186: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low value

claimInline uses a boolean, so sibling inline children clear each other.

claimInline sets inlineClaimed to true and registers a cleanup that sets it to false. If one Action wraps more than one inline child (for example a ComposerActions.Inline and a ComposerActions.ActionButton), the first cleanup clears the flag while another inline child is still mounted. The action then leaves the fit calculation and moves to the overflow menu.

A counter keeps the flag correct for any number of inline children.

  • When a resize jumps across multiple slot boundaries, this returns the entire previous count unless the width clears the hysteresis for the highest fits value. For example, moving directly from 1 slot to a budget that safely fits 2 but nominally fits 3 leaves only 1 action visible indefinitely. Apply hysteresis to the expansion budget so intermediate slots can still become visible.

…ration deleted

The chat store (useChatSession) now lives on PaneContext: PaneProvider creates
it for quick/pip, and the panel route creates it in a keyed PanelSessionPane
above the Outlet. RefreshButton reads pane.chat directly, so RefreshHandle,
registerRefresh, and both refreshHandle signals are gone.

Panel consequences: the chat SSE connection survives view-tab switches (pinned
by a new browser test), and the refresh button is gated on the active tab by
the route itself. The keyed boundary now wraps the header, so an in-route
session switch recreates it.

…oundary removed

pane.chat becomes Accessor<ChatSession> backed by createMemo keyed on
{sessionId, connectionGeneration}; memo re-run disposes the previous store
(useChat teardown is onCleanup-based). The hand-rolled keyed Show around the
panel header is deleted — the router already keyed-remounts the route
component on param change (match.id embeds the path), so the boundary was
redundant. The memo's own reactivity carries the generation-bump rebuild,
which no remount covers.

These lines replace the ChatSession when connectionGeneration changes. The supplied ChatPane consumer snapshots pane.chat() once into a non-reactive chat constant. After reconnect, ChatPane continues using the previous session while the provider exposes the replacement and the old useChat store is cleaned up.

…on cell, uncontrolled menu, slot compound API

The coordinator owns a single registry signal ({actions, slots, inlineClaims,
menuEntries}) with register-once + onCleanup — Action's two signals are gone.
Region widths live in one store fed by a single batched ResizeObserver
(createElementSize rejected with a probe: three observers expose an
inconsistent intermediate width pair that falsely dismisses the menu). The
overflow menu is uncontrolled — Ark's machine owns open state, the menu
unmounts when everything fits, and onOverflowDismissed fires from a
cleanup-while-open guard; the last createEffect is gone. Host props
leading/trailing/triggerContent become ComposerActions.Leading/Trailing/Trigger
registration slots. pane-composer's inputHandle signal becomes a plain let.

jsx-tokenizer was tried for registration and reverted: Solid's Provider and
Suspense resolve children by calling zero-arg functions, destroying tokens, so
tokens cannot cross extension mount boundaries.

Keep cleanup scoped to the specific registration.

Line 146 removes every inline claim for the action. If one of multiple mounted Inline children disposes, the action becomes ineligible for inline placement while another child remains mounted.

Line 155 removes menu entries from any action that uses the same entry.key. Dispose only the claim or menu-registration instance that this call added. Add disposal coverage for both cases.

  • The story adds an em dash in a TypeScript string literal, contrary to the repository code law.

  • Avoid the newly introduced non-null assertion; explicitly narrow the split result before accessing code.

  • Both new accesses rely on prohibited non-null assertions. Narrow each nullable split result so a regression returning null fails clearly without bypassing the type system.

  • disabled can diverge between the two renderings of a paired action: here the button combines local.disabled, but OverflowGroup disables its menu items only from the parent Action accessor. A nested ActionButton disabled={...} is therefore disabled inline and enabled after collapse. Either disallow child-level disabled state for paired buttons or feed it into the paired action's shared disabled source.
    packages/ui-kit-chat/src/primitives/composer/composer-actions-core.ts:96
  • A negative public maxInlineAuto makes inlineAutoCount negative, so slice(0, -1) keeps all but the last auto action instead of keeping none. Clamp and normalize the cap before it reaches slice.
    apps/conciv/src/composer/launch-menu.tsx:50
  • This newly added UI string uses an em dash, which the repository code law prohibits in string literals. Use punctuation such as a colon instead.

This issue also appears on line 82 of the same file.

…s from codex, copilot, and coderabbit

- Send keeps type=submit regardless of consumer spread; clicking a Send
  wrapped in TooltipIconButtonSlot submits again (browser test).
- quick/pip chat stores key on {sessionId, connectionGeneration} like the
  panel, and quick/pip remount ChatPane on generation bumps (browser test
  drives a generation bump against a gated draft read).
- slotRender resolves duplicate slot registrations last-wins (findLast).
- claimInline cleanup removes exactly one claim, so an action with two live
  inline claims survives one child disposing.
- tanstack inspector chip pins visible=always: unpinned Inline actions have
  no menu fallback and conciv caps inline autos at zero, so the chip was
  unreachable; test premise fixed and dead widenPanel helper removed.
- extension-compiler node split strips ObjectMethod Component/Surface and
  the Object.assign(extension, {...}) form the site docs teach.
- em dashes purged from code string literals (repo law).
- docs synced to the shipped API: changeset, conciv-extensions and
  conciv-develop skills, site widget-ui.mdx, superseded notes on the two
  planning docs.

…churn; e2e locators follow shipped labels

slotRender read the whole registry signal inside the host's JSX, so every
action registration, inline claim, or menu-entry swap tore down and re-created
the leading/trailing/trigger subtrees. That churn destroyed SessionModelSelector
on each meta.models error, and the fresh query observer's retryOnMount refetch
fed the loop: the retry button never survived to be seen, and CI's slower send
clicks landed on a mid-recreation trailing subtree. Per-slot createMemos keep
the render identity stable; a browser regression test pins that trailing-slot
state survives overflow-entry swaps (red-verified against the old code).

Stale e2e locators aligned to shipped UI: attachment button is 'Add an
attachment', launch entries and new-session live in the overflow menu.

… logo

The pinned status chip keeps its role and tooltip; the generic Waypoints icon
becomes the TanStack mark, copied verbatim from @tanstack/router-devtools-core
with per-instance createUniqueId gradient/mask scoping and consumer-driven
sizing.

…, no non-null assertions in tests

The composer scaffold's only consumer is the in-chat authoring agent (the
conciv_extensions tool returns code as a string; nothing programmatic writes
package.json), so the @conciv/ui-kit-chat dependency requirement now rides the
two descriptions that agent actually reads: the composer slot catalog entry and
the tool description. Tests pin both. Split-extension tests narrow the split
result through a helper instead of out!.code.
