* feat(rag): add knowledge base migration from v4.9.0 to plugin architecture
Rewrite dbm020 to backup old knowledge_bases data and preserve
external_knowledge_bases table. Add migration API endpoints and
frontend dialog so users can opt-in to auto-install LangRAG plugin
and restore their knowledge bases with original UUIDs preserved.

* fix: coerce pipeline config types at load time using metadata definitions
Pipeline configs stored in SQLAlchemy JSON columns can have values turned
into strings after UI edits (e.g. "120" instead of 120), causing runtime
arithmetic/logic errors. Add centralized type coercion in load_pipeline()
that leverages existing metadata YAML type definitions (integer, number,
float, boolean) to convert values before they reach downstream stages.

- Added dynamic column measurement to adjust the number of visible plugins based on the grid layout.
- Implemented auto-advance feature for pagination every 5 seconds when there are more plugins than the visible count.
- Updated pagination controls to reflect the current page accurately.
- Refactored code to improve readability and maintainability.
The getTitle fallback order was reversed, always showing the UUID

* [issue:1933] RAG engine plugin architecture (#1967)
* refactor: migrate RAG knowledge services to a plugin-oriented host service architecture.
* feat(rag): phase 2 core refactor with RPC Action handlers
* feat: 为 RAG 插件添加知识库创建和删除事件通知，并优化了 RAG 动作的参数传递和枚举使用。
* feat: 统一知识库管理为RAG引擎，支持动态配置并移除旧的外部知识库组件。
* refactor(rag): remove plugin_adapter, inline logic into RuntimeKnowledgeBase
BREAKING CHANGE: RAGPluginAdapter has been removed. All plugin
communication is now handled directly by RuntimeKnowledgeBase.
Architecture change:
- Before: RuntimeKnowledgeBase → RAGPluginAdapter → plugin_connector
- After: RuntimeKnowledgeBase → plugin_connector (direct)
Changes to kbmgr.py (RuntimeKnowledgeBase):
- Remove RAGPluginAdapter import and usage
- Inline plugin communication methods:
- _on_kb_create(): Notify plugin when KB is created
- _on_kb_delete(): Notify plugin when KB is deleted
- _ingest_document(): Call plugin for document ingestion
- _retrieve(): Call plugin for retrieval
- _delete_document(): Call plugin to delete document
- Simplify dispose(): Only notify plugin, no built-in VDB assumption
Changes to base.py (KnowledgeBaseInterface):
- Remove get_type() abstract method (outdated internal/external concept)
- Add get_rag_engine_plugin_id() abstract method
Changes to localagent.py:
- Remove get_type() call
- Simplify top_k retrieval from KB entity
Deleted files:
- pkg/rag/knowledge/plugin_adapter.py
Benefits:
- Reduced abstraction layer, simpler code
- Plugin communication logic centralized in RuntimeKnowledgeBase
- Easier to understand and maintain

* refactor(api): remove ExternalKnowledgeBase infrastructure
BREAKING CHANGE: ExternalKnowledgeBase has been completely removed.
All knowledge bases are now unified under the single KnowledgeBase model,
differentiated by their rag_engine_plugin_id.
Deleted files:
- pkg/api/http/controller/groups/knowledge/external.py
(ExternalKBController with /external-bases routes)
- pkg/api/http/service/external_kb.py
(ExternalKnowledgeBaseService)
- pkg/rag/knowledge/external.py
(ExternalKnowledgeBase implementation)
Modified files:
- pkg/entity/persistence/rag.py:
Remove ExternalKnowledgeBase SQLAlchemy table definition
- pkg/core/app.py:
Remove external_kb_service attribute from LangBotApplication
- pkg/core/stages/build_app.py:
Remove external_kb_service initialization
Migration notes:
- Existing external knowledge base data should be migrated manually
- API consumers should use /api/v1/knowledge/bases for all KB operations
- Use /api/v1/knowledge/engines to discover available RAG engines

* refactor(plugin): remove list_knowledge_retrievers from connector
Remove deprecated list_knowledge_retrievers functionality from the
plugin communication layer. This aligns with the SDK change that
removed the LIST_KNOWLEDGE_RETRIEVERS action.
Changes:
- connector.py: Remove list_knowledge_retrievers() method
- handler.py: Remove list_knowledge_retrievers() handler
The functionality is replaced by the new /api/v1/knowledge/engines
endpoint which lists available RAGEngine components with their
capabilities and configuration schemas.

* refactor(service): update knowledge service with capability-based checks
Replace type-based checks with capability-based checks for file
operations, aligning with the unified knowledge base architecture.
Changes to knowledge.py:
- store_file(): Replace get_type() check with doc_ingestion capability check
- delete_file(): Replace get_type() check with doc_ingestion capability check
- list_rag_engines(): Remove list_knowledge_retrievers call, simplify to
only list RAGEngine components (KnowledgeRetriever type removed)
Changes to pipelines.py:
- Minor cleanup related to knowledge base references
The capability-based approach allows RAG engines to declare their
supported features (doc_ingestion, chunking_config, rerank, hybrid_search)
and the system responds accordingly, rather than hardcoding behavior
based on internal/external type distinction.

* feat(web): unify knowledge base UI, remove external KB components
BREAKING CHANGE: The internal/external knowledge base distinction
has been removed from the frontend. All knowledge bases are now
displayed in a unified list, differentiated by their RAG engine.
Changes to page.tsx:
- Remove Tab component (内置/外置 tabs)
- Remove selectedKbType state
- Unified knowledge base list display
- Single "Create Knowledge Base" button for all types
Changes to KBDetailDialog.tsx:
- Remove kbType prop
- Simplify dialog logic for unified KB handling
- Documents menu item conditionally shown based on doc_ingestion capability
Changes to KBForm.tsx:
- Remove retriever type handling code
- Simplify form for unified KB creation
- Dynamic form rendering based on RAG engine's creation_schema
Changes to KBCardVO.ts:
- Remove 'type' field from KBCardVO interface
Changes to BackendClient.ts:
- Remove all external KB related methods:
- getExternalKnowledgeBases()
- getExternalKnowledgeBase()
- createExternalKnowledgeBase()
- updateExternalKnowledgeBase()
- deleteExternalKnowledgeBase()
- retrieveFromExternalKnowledgeBase()
Changes to api/index.ts:
- Remove ExternalKnowledgeBase interface definition
UI/UX improvements:
- Users no longer need to understand internal vs external distinction
- RAG engine selection is now the primary differentiator
- Documents panel visibility is capability-driven (doc_ingestion)

- Add filter_utils.py with normalize_filter() and strip_unsupported_fields()
- Implement filter in search() and add delete_by_filter() for all backends:
Chroma/SeekDB (native passthrough), Qdrant (translated to models.Filter),
Milvus (translated to expr string), pgvector (translated to SQLAlchemy conditions)
- Milvus/pgvector limited to {text, file_id, chunk_uuid}; other fields logged and ignored
- Replace delete_by_filter() NotImplementedError with backend delegation in mgr.py
- Populate retrieval_context['filters'] from settings in kbmgr._retrieve()

the documents parameter in add_embeddings(), not just metadata.

Change single quote escaping from MySQL-style \' to standard SQL ''
(doubled quote). The backslash escape is not recognized by OceanBase

text contains apostrophes (e.g. O'Shea in academic citations).

ModuleNotFoundError if those packages weren't installed.
Now s3storage is only imported when S3 storage is actually configured.
* perf: reduce memory usage by ~200MB+ at startup
Two key optimizations:
1. Use importlib.util.find_spec() instead of __import__() in dependency
checking. find_spec() only locates modules without executing them,
avoiding loading all 36 dependencies (~222MB) into memory at startup.
2. Introduce shared aiohttp.ClientSession via httpclient module.
Previously, every HTTP request created a new ClientSession, which
creates a new TCPConnector and SSL context, loading system root
certificates each time (~270MB total allocations observed via memray).
Now all HTTP client code reuses shared sessions.
- satori.py and coze_server_api/client.py are left unchanged as they
create one session per adapter lifecycle (not per-request).
Profiling data (memray):
- Peak memory: 403MB
- SSL context creation: 270MB / 6.7M allocations (67% of total)
- Dependency import: 222MB (55% of peak)
- Expected reduction: 150-350MB at startup
* fix: remove unused aiohttp imports (ruff F401)
* style: ruff format
- Updated BOOLEAN case to default to false when field.value is undefined.
- Updated SELECT case to default to an empty string when field.value is undefined.
- Updated BotForm to serialize adapter_config for stable useEffect dependency.
- Refactored DynamicFormComponent to track last emitted values, avoiding unnecessary re-renders when form values remain unchanged.
* feat: add in-product survey system
- SurveyManager: event-based trigger, Space API communication
- Trigger on first successful non-WebSocket response
- Backend API: /api/v1/survey/{pending,respond,dismiss}
- Frontend: floating survey widget with progressive questions
- Flat radio/checkbox style (not dropdown Select)
* fix: persist triggered survey events to disk across restarts
Store triggered events in data/survey_triggered_events.json so that
restarting the process doesn't re-query Space for already-triggered events.
* fix: use metadata table for survey event persistence instead of file
Store triggered events in the existing metadata KV table
(key='survey_triggered_events') instead of a standalone JSON file.
* fix: ruff format and prettier fixes
* feat: add session message monitoring tab to bot detail dialog
Add a new "Sessions" tab in the bot detail dialog that displays
sent & received messages grouped by sessions. Users can select
any session to view its messages in a chat-bubble style layout.
Backend changes:
- Add sessionId filter to monitoring messages endpoint
- Add role column to MonitoringMessage (user/assistant)
- Record bot responses in monitoring via record_query_response()
- Add DB migration (dbm019) for the new role column
Frontend changes:
- New BotSessionMonitor component with session list + message viewer
- Add Sessions sidebar tab to BotDetailDialog
- Add getBotSessions/getSessionMessages API methods to BackendClient
- Add i18n translations (en-US, zh-Hans, zh-Hant, ja-JP)

* refactor: remove outdated version comment from PipelineManager class
* fix: bump required_database_version to 19 to trigger monitoring_messages.role migration
* fix: prevent session message auto-scroll from pushing dialog content out of view
Replace scrollIntoView (which scrolls all ancestor containers) with
direct scrollTop manipulation on the ScrollArea viewport. This keeps
the scroll contained within the messages panel only.
* ui: redesign BotSessionMonitor with polished chat UI
- Wider session list (w-72) with avatar circles and cleaner layout
- Richer chat header with avatar, platform info, and active indicator
- User messages now use blue-500 (solid) instead of blue-100 for
clear visual distinction
- Metadata (time, runner) shown on hover below bubbles, not inside
- Proper empty state illustrations for both panels
- Better spacing, rounded corners, and shadow treatment
- Consistent dark mode styling
* fix: infinite re-render loop in DynamicFormComponent
The useEffect depended on onSubmit which was a new closure every
parent render. Calling onSubmit inside the effect triggered parent
state update → re-render → new onSubmit ref → effect re-runs → loop.
Fix: use useRef to hold a stable reference to onSubmit, removing it
from the useEffect dependency array.
Also add DialogDescription to BotDetailDialog to suppress Radix
aria-describedby warning.
* fix: remove .html suffix from docs.langbot.app links (Mintlify migration)
* style: fix prettier and ruff formatting

* feat(platform): add Forward message support for aiocqhttp adapter
- Add _send_forward_message method to send merged forward cards via OneBot API
- Support NapCat's send_forward_msg API with fallback to send_group_forward_msg
- Fix MessageChain deserialization for Forward messages in handler.py
- Properly deserialize nested ForwardMessageNode.message_chain to preserve data
This enables plugins to send QQ merged forward cards through the standard
LangBot send_message API using the Forward message component.
* style: fix ruff lint and format issues
- Remove f-string prefix from log message without placeholders
- Apply ruff format to aiocqhttp.py and handler.py
* refactor: remove custom deserializer, rely on SDK for Forward deserialization
- Remove _deserialize_message_chain from handler.py; use standard
MessageChain.model_validate() (Forward handling fixed in SDK via
langbot-app/langbot-plugin-sdk#38)
- Fix group_id type: use int instead of str for OneBot compatibility
- Add warning log when Forward message is used with non-group target
* chore: bump langbot-plugin to 0.2.7 (Forward deserialization fix)

DynamicFormComponent uses form.watch(callback) to notify parent of form
values, but react-hook-form's watch callback only fires on subsequent
changes, not on mount. This causes PluginForm's currentFormValues to
remain as {} if the user saves without modifying any field, overwriting
the existing plugin config with an empty object in the database.
* fix: Add the file upload function and optimize the media message processing
* fix: Optimize the message processing logic, improve the concatenation of text elements and the sending of media messages
* fix: Simplify the file request construction and message processing logic to enhance code readability
