After verifying that the OpenClaw gateway's chat.send WebSocket RPC
accepts an 'attachments' array (confirmed from openclaw/openclaw source
and documentation), implement end-to-end image/file attachment support
for instance chat:
Bridge (openclaw-client.ts):
- chatSendAndWait() now accepts optional `attachments[]` parameter
- Passes attachments to chat.send RPC only when non-empty
Bridge (index.ts):
- /task-async accepts `attachments[]` from request body
- Forwards to chatSendAndWait unchanged
Backend (agent.controller.ts):
- executeInstanceTask() accepts IT0 attachment format
{ base64Data, mediaType, fileName? }
- Converts to OpenClaw format { name, mimeType, media: "data:..." }
- Saves attachments to conversation history via contextService
- Forwards to bridge via bridgeAttachments spread
Flutter (agent_instance_chat_remote_datasource.dart):
- createTask() now includes attachments in POST body when present
Flutter (chat_page.dart):
- Reverted Fix 5 (disabled button) — attachment button fully enabled
in instance mode since the bridge now supports it
Attachment format (OpenClaw wire):
{ name: string, mimeType: string, media: "data:<mime>;base64,<data>" }

Fix 2 — Callback timeout wiring:
- Store callbackTimer in pendingCallbackTimers Map after creation
- handleOpenClawAppCallback clears the timer immediately on arrival,
preventing spurious "timeout" errors when the bridge replies in time
Fix 3 — Provider scope isolation:
- Override agentStatusProvider and robotStateProvider in child ProviderScope
so the robot avatar/FAB reflects the instance chat state, not iAgent's
Fix 4 — Voice routing to OpenClaw:
- AgentInstanceChatDatasource.sendVoiceMessage() now calls transcribeAudio()
then routes the transcript through instance-specific createTask() endpoint,
ensuring voice messages reach the user's OpenClaw agent, not iAgent
Fix 5 — Attachment UI in instance mode:
- Attachment button shown as disabled (onPressed: null) with explanatory
tooltip ("附件功能暂不支持智能体对话") when agentName != null
- Prevents misleading UX where attachments appear to work but are silently
dropped by the OpenClaw bridge
Fix 6 — DB schema template:
- Add agent_instance_id UUID NULL to agent_sessions table in migration 002
(tenant schema template) so new tenants get the column from creation
- Add covering index idx_agent_sessions_instance for efficient instance queries
All TypeScript and Flutter analyze checks pass clean.
