When the agent fails due to missing API key, the error banner now
shows a "Configure" button that opens the same ApiKeyDialog (or
OAuthDialog) used on the home page. After successful configuration
the error clears and the user can immediately start chatting.

StreamPayload.event was missing the agent_error event type, causing
TypeScript errors in useGatewayChat and useLocalChat where the
comparison payload.event.type === "agent_error" had no type overlap.

Desktop path already forwards agent_error to chat.setError() via
use-local-chat.ts, but the Web/Gateway path was missing this handling.
Add agent_error interception in the StreamAction branch so Web clients
render LLM errors the same way Desktop does.

When the agent encounters an error (e.g. no API key configured),
the Chat UI now shows an error banner instead of silently hanging.
The user can still type and retry after fixing their configuration.
- Add AgentErrorEvent to SDK stream types
- Forward agent_error events through IPC to renderer
- Handle error events in useLocalChat hook
- Keep chat input enabled for AGENT_ERROR (retriable)

After the chat refactoring moved state management to @multica/hooks,
the Zustand stores (useConnectionStore, useMessagesStore, useAutoConnect)
are no longer imported by any application code. This removes them along
with their unused dependencies (zustand, uuid, react).
- Delete connection-store.ts, messages.ts, use-auto-connect.ts
- Extract Message/ToolStatus types into types.ts (preserves UI imports)
- Remove saveConnection/loadConnection/clearConnection from connection.ts
- Drop zustand, uuid, react deps from package.json

Return latest messages by default instead of oldest. Support paginated
loading of older messages when scrolling up via IntersectionObserver,
with scrollHeight compensation to preserve scroll position.

Move gateway-specific chat logic into dedicated useGatewayChat hook.
useChat remains a pure state hook with no IO. Update ChatView props,
remove legacy chat.tsx and connect-prompt.tsx.

Extract StatusWrapper to replace duplicated fullscreen/inline wrapper in
ConnectionStatus and RejectedStatus. Extract PairingHeader to replace
repeated title+description blocks in mobile and desktop views. Make
desktop container mb responsive (mb-14 sm:mb-28).

Move all CSS out of globals.css into inline styles within each component.
Loading (Apple-style radiating lines) for passive waiting states;
Spinner (3x3 grid pulse) for active processing/execution states.
Switch device-pairing ConnectionStatus from Loading to Spinner.

- Extract ChatView from web chat-page into packages/ui as a prop-driven
component (accepts UseChatReturn shape, no transport dependency)
- Move DevicePairing from apps/web to packages/ui with locally defined
ConnectionIdentity type (no @multica/hooks dependency)
- Create @multica/hooks package with useGatewayConnection and useChat
(moved from apps/web/hooks)
- Add isLoadingHistory state to useChat with skeleton loading in ChatView
- Add MulticaIcon (pure CSS asterisk via clip-path, adapts to theme)
- Slim web chat-page.tsx from 188 to 65 lines (just wires hooks to UI)
Desktop can now reuse ChatView and DevicePairing directly.

- Wrap maybeCompact() in try/catch to ensure compaction_end always fires
- Widen multicaListeners type to match subscribeAll() callback signature
- Import CompactionEndEvent from SDK instead of inline type casts
- Add doc comment explaining reason field type difference (agent vs SDK)

Forward compaction_start/compaction_end events through Hub (Gateway path)
and Desktop IPC (local path) to the Zustand messages store. Adds
CompactionEvent types to the SDK, compacting/lastCompaction state to
useMessagesStore, and event routing in both connection-store and
use-local-chat.

Add ExecApprovalItem for human-in-the-loop command approval with uniform
outline buttons (Allow/Always/Deny), countdown timer, and command display.
Refine ToolCallItem and ThinkingItem: transparent by default, unified
bg-muted/30 wrapper on expand with seamless button+content integration.

Add ThinkingItem component for displaying LLM extended thinking. Renders
as a collapsible row (matching ToolCallItem style) with expand to reveal
thinking text. MessageList now extracts and renders ThinkingContent blocks
before text content, matching the LLM output order.

Add break-words to markdown-content wrapper so URLs and file paths in
<p>, <li>, <a> etc. wrap at container boundary instead of overflowing.

Add @utility container (w-full max-w-4xl mx-auto) to globals.css and
create a reusable Loading spinner component for consistent loading states.

Add a "verifying" connection state between "connected" and "registered"
so collaborators see clear feedback while waiting for the device owner
to approve their connection on Desktop.
Changes across the stack:
- Hub: verify RPC returns isNewDevice flag to distinguish new vs whitelisted
- SDK: emit "verifying" state before verify RPC, pass isNewDevice through
- Store: capture isNewDevice via onVerified, capture rejection via onError
- UI: ConnectionStatus (waiting), RejectedStatus (declined), and
verify success overlay (approved) replace the stuck scanner screen

Replace overlay approach with conditional rendering for paste validation
states. Success shows checkmark icon with 600ms delay before connecting,
error shows alert with message and auto-resets after 2s. Improves
Connecting text visibility.

Rewrite user-facing text to be source-agnostic and result-focused:
- Connect prompt: "Scan to start" / "Scan a QR code to use an Agent"
- Empty chat: "Your Agent is ready"
- Input placeholder: "Ask your Agent..." / "Scan QR code to get started"
- Bump chat input font to text-base for mobile readability

Replace sheet-based scanner with inline QrScannerView, add scan/paste
mode toggle for desktop, and fullscreen camera overlay for mobile.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Rewrite QrScannerView with full state machine (idle/requesting/scanning/
detected/success/error), corner bracket animations snapping to QR
cornerPoints, flash toggle, and haptic feedback.
Add QrScannerSheet as bottom sheet wrapper for mobile. Simplify
ConnectPrompt to use useIsMobile() — mobile shows scan button + sheet,
desktop shows paste-only UI.
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add cornerPoints, hasFlash/toggleFlash, and manual start/stop/pause
to useQrScanner. Change enabled default to false for click-to-start.
Add scoped CSS animations for scanner bracket breathing and error shake.

Swap the plain <textarea> for a minimal Tiptap (ProseMirror) editor
with IME-safe Enter-to-submit, Shift+Enter newline, placeholder
support, and an optional imperative ref (getText/setText/focus/clear).
All rich-text extensions are disabled — only plain text is allowed.

- Handle `action: "error"` messages in connection-store (e.g. UNAUTHORIZED)
- Widen lastError type to `{code, message}` to support all error codes
- Display dismissible error banner in Chat with role="alert" and aria-live
- Add accessible close button with focus-visible ring

Tools were only visible after tool_execution_end because the UI relied
solely on toolResult messages (created at tool_execution_start, ~8ms
before end). Now MessageList detects toolCall blocks in the streaming
assistant message and renders them as "running" ToolCallItems immediately.
Once a real toolResult message arrives, the synthetic one is replaced.
- Add resolvedToolCallIds set to deduplicate assistant vs toolResult renders
- Extract getTextContent to shared utils to avoid duplication
- Wrap MessageList and ToolCallItem in memo for performance
- Add accessible region/tabIndex to expanded result panel
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Remove backward-compatible aliases (TextBlock, ThinkingBlock, ToolCallBlock)
and extractTextFromEvent from SDK — unused after prior refactors
- Add explicit ContentBlock doc comment explaining the wider union tradeoff
- Scope endStream tool interruption to the same agentId (prevents
cross-agent interference in multi-agent scenarios)
- Handle tool_execution_update event (no-op for now, avoids unhandled case)
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Replace hugeicons status icons with CSS colored dots + glow-pulse
animation for running state (honors prefers-reduced-motion)
- Add smart subtitles from toolArgs: file basename, command preview,
search pattern, URL hostname
- Add right-aligned stats: line count, match count, file count
- Add hover chevron for expand/collapse affordance
- Fix accessibility: aria-label, aria-expanded, focus-visible ring
- Store toolArgs in Message (was received but discarded)
- Extract toolArgs from assistant ToolCall blocks during fetchHistory
- Add --tool-running/success/error CSS variables with dark mode support
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Message.content is now ContentBlock[] (was string), supporting
text, thinking, toolCall, and image blocks
- Add toolResult role with toolCallId, toolName, toolStatus, isError
- Add startToolExecution/endToolExecution to MessagesStore
- MessageList renders toolResult messages via ToolCallItem
- Extract text from ContentBlock[] for markdown rendering

Replace hand-written message/content types in @multica/sdk with
`import type` from @mariozechner/pi-ai and @mariozechner/pi-agent-core.
This ensures compile-time correctness and eliminates type drift between
backend and frontend (e.g. "tool_use" vs "toolCall", "tool_result" vs
"toolResult").
- stream.ts: re-export TextContent, ThinkingContent, ToolCall,
ImageContent from pi-ai; use AgentEvent from pi-agent-core
- rpc.ts: AgentMessageItem = pi-ai Message (no more manual mirroring)
- connection-store.ts: use SDK types instead of inline hand-written ones
- ContentBlock now includes ImageContent to match backend reality

Update StreamMessageEvent content type to include thinking blocks.
Add extractThinkingFromEvent() helper and export it, enabling clients
to access reasoning content from streamed agent responses.
