-13,6 +13,17 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). ### Changed +- **Knowledge Base embedding model binding (breaking / migration)** + The Knowledge Base now treats the **Model Hub ID** as the single source of truth for embedding model identity: + - `collection_metadata.embedding_model_id` stores the Hub ID (trimmed; no other normalization). + - Embeddings tables are named by Hub ID: `embeddings_{to_model_tag(hub_id)}`. + - The `model` field stored alongside each embedding vector is the Hub ID. + + **Migration / backward compatibility:** Older deployments may have created embeddings tables using the provider `model_name` + (e.g. `embeddings_text-embedding-v4`). During search and embedding reads, the system will **try the new Hub-ID table first** + and automatically **fall back to the legacy table name** derived from the resolved `model_name` when the new table is missing. + Rebuild/inference helpers were updated to prefer Hub IDs when they can be resolved from Model Hub metadata. + - **Knowledge Base upload: default parse method (breaking)** The default parse method on the KB detail upload form is now `"default"` instead of `"pypdf"`. The backend chooses the parser by file type (e.g. .docx, .pdf). If you rely on the previous default (always use PyPDF), select `"pypdf"` explicitly in the parse method dropdown when uploading. diff --git a/scripts/set_nanwang_embedding_model_id.py b/scripts/set_nanwang_embedding_model_id.py index 0e57dbd9a..a5757b8bb 100644 --- a/scripts/set_nanwang_embedding_model_id.py +++ b/scripts/set_nanwang_embedding_model_id.py @@ -52,4 +52,3 @@ def main() -> None: if __name__ == "__main__": main() - diff --git a/src/xagent/core/tools/core/RAG_tools/core/config.py b/src/xagent/core/tools/core/RAG_tools/core/config.py index 2a75c47bd..5ddb5cd13 100644 --- a/src/xagent/core/tools/core/RAG_tools/core/config.py +++ b/src/xagent/core/tools/core/RAG_tools/core/config.py @@ -54,6 +54,10 @@ Set to 0 to disable any artificial throttling.

Storage Layer: - Extend MetadataStore with config operations (save/get_collection_config) - Extend VectorIndexStore with aggregate and delete operations (aggregate_collection_stats, aggregate_document_stats, delete_collection_data) - Implement all contracts in LanceDBMetadataStore and LanceDBVectorIndexStore - Add factory singleton (get_kb_write_coordinator) for coordinated access API Layer (api/kb.py): - Replace direct get_connection_from_env() calls with storage abstractions - Remove manual embeddings table updates in rename_collection_api - Use get_metadata_store() and get_vector_index_store() throughout Management Layer (management/collections.py): - Refactor list_collections() to use VectorIndexStore.aggregate_collection_stats() - Refactor delete_collection() to use VectorIndexStore.delete_collection_data() - Refactor cancel_collection() to use VectorIndexStore.list_document_records() - Refactor get_document_stats() to use VectorIndexStore.aggregate_document_stats() - Remove 324 lines of direct LanceDB operations Tests: - Add 90 lines of new storage layer tests - Update multitenancy tests to mock storage abstractions - Update kb_dir API tests for new mock patterns - All 767 RAG tests passing Phase 1A Constraints Met: - Interface decoupling only (no physical database split) - doc_id maintained as primary key - Backward compatibility via get_raw_connection() on all contracts - No changes to existing data schemas --- .../core/tools/core/RAG_tools/core/config.py | 19 + .../core/RAG_tools/management/collections.py | 485 +++++++++-------- .../core/RAG_tools/retrieval/search_engine.py | 69 ++- .../core/RAG_tools/retrieval/search_sparse.py | 72 ++- .../tools/core/RAG_tools/storage/contracts.py | 269 +++++++++- .../core/RAG_tools/storage/lancedb_stores.py | 488 +++++++++++++++++- .../core/RAG_tools/utils/filter_utils.py | 66 +++ .../core/RAG_tools/utils/string_utils.py | 34 +- .../vector_storage/vector_manager.py | 13 + src/xagent/web/api/kb.py | 59 +-- .../RAG_tools/storage/test_lancedb_stores.py | 90 ++++ .../tools/core/RAG_tools/test_multitenancy.py | 107 ++-- .../test_embeddings_forward_migration.py | 16 +- tests/web/api/test_kb_dir.py | 24 +- 14 files changed, 1372 insertions(+), 439 deletions(-) create mode 100644 src/xagent/core/tools/core/RAG_tools/utils/filter_utils.py diff --git a/src/xagent/core/tools/core/RAG_tools/core/config.py b/src/xagent/core/tools/core/RAG_tools/core/config.py index 5ddb5cd13..45495aa43 100644 --- a/src/xagent/core/tools/core/RAG_tools/core/config.py +++ b/src/xagent/core/tools/core/RAG_tools/core/config.py @@ -1,5 +1,6 @@ from __future__ import annotations +import os from dataclasses import dataclass from pathlib import Path from typing import Any, Dict, Final, Mapping, Sequence @@ -69,6 +70,24 @@ "(user_id IS NULL and user_id IS NOT NULL)" ) +ENABLE_AUTO_EMBEDDINGS_MIGRATION: Final[bool] = ( + os.getenv("ENABLE_AUTO_EMBEDDINGS_MIGRATION", "false").lower() == "true" +) +""" +Enable automatic forward migration of legacy embeddings tables. + +When disabled (default), the system will not automatically migrate data from +legacy table names (embeddings_{model_name}) to new Hub ID-based names +(embeddings_{hub_id}).

Core Changes: - Add StorageFactory unified class for managing all store singletons - Add IngestionStatusStore contract with sync/async methods - Implement LanceDBIngestionStatusStore with full CRUD operations - Refactor status.py to use storage abstraction layer - Add stub contracts for PromptTemplateStore and MainPointerStore Storage Abstraction Layer: - contracts.py: Add IngestionStatusStore, PromptTemplateStore, MainPointerStore - factory.py: Replace standalone functions with StorageFactory class - Thread-safe singleton pattern with double-checked locking - Unified reset_all() method for test isolation - lancedb_stores.py: Implement LanceDBIngestionStatusStore - Sync methods: write_ingestion_status, load_ingestion_status, clear_ingestion_status - Async methods: *_async variants (delegates to sync for now, true async I/O in Phase 1B) - Helper methods: _build_base_filter, _build_load_filter, _combine_filters Business Logic Refactoring: - status.py: Remove raw connection usage, use get_ingestion_status_store() - Maintain backward-compatible public API - Add async variants: write_ingestion_status_async, load_ingestion_status_async, clear_ingestion_status_async Tests: - test_status.py: Add 4 async tests (12 total tests passing) - test_write_ingestion_status_async - test_write_ingestion_status_overwrites_existing_async - test_load_ingestion_status_by_collection_async - test_clear_ingestion_status_async Related Files: - storage/__init__.py: Export new contracts and factory functions This completes Phase 2.1 of the storage decoupling plan (plan/storage-decoupling-phase2.md). Next phases will extend VectorIndexStore for index management and implement PromptTemplateStore. --- .../core/RAG_tools/chunk/chunk_document.py | 112 +- .../core/RAG_tools/file/register_document.py | 98 +- .../management/collection_manager.py | 2 +- .../tools/core/RAG_tools/management/status.py | 212 +-- .../core/RAG_tools/parse/parse_display.py | 46 +- .../core/RAG_tools/parse/parse_document.py | 157 +-- .../core/RAG_tools/retrieval/search_dense.py | 116 ++ .../core/RAG_tools/retrieval/search_engine.py | 181 ++- .../core/RAG_tools/retrieval/search_sparse.py | 332 ++++- .../tools/core/RAG_tools/storage/__init__.py | 21 +- .../tools/core/RAG_tools/storage/contracts.py | 409 +++++- .../tools/core/RAG_tools/storage/factory.py | 280 +++- .../core/RAG_tools/storage/lancedb_stores.py | 961 ++++++++++++- .../core/RAG_tools/utils/filter_utils.py | 49 +- .../core/RAG_tools/utils/string_utils.py | 25 +- .../vector_storage/vector_manager.py | 258 ++-- .../RAG_tools/chunk/test_chunk_document.py | 189 ++- .../RAG_tools/file/test_register_document.py | 27 +- .../core/RAG_tools/management/test_status.py | 114 +- .../RAG_tools/parse/test_parse_document.py | 186 ++- .../RAG_tools/retrieval/test_search_dense.py | 229 ++- .../RAG_tools/retrieval/test_search_sparse.py | 573 ++++---- .../RAG_tools/storage/test_lancedb_stores.py | 183 +++ .../test_embeddings_forward_migration.py | 12 +- .../vector_storage/test_vector_manager.py | 1236 +++++------------ .../test_list_candidates.py | 3 +- 26 files changed, 3896 insertions(+), 2115 deletions(-) diff --git a/src/xagent/core/tools/core/RAG_tools/chunk/chunk_document.py b/src/xagent/core/tools/core/RAG_tools/chunk/chunk_document.py index 5ec874a8f..22870d47d 100644 --- a/src/xagent/core/tools/core/RAG_tools/chunk/chunk_document.py +++ b/src/xagent/core/tools/core/RAG_tools/chunk/chunk_document.py @@ -22,14 +22,9 @@ DocumentValidationError, ) from ..core.schemas import ChunkStrategy -from ..LanceDB.schema_manager import ensure_chunks_table from ..storage.factory import get_vector_index_store -from ..storage.contracts import build_filter_from_dict from ..utils.hash_utils import compute_chunk_hash -from ..utils.lancedb_query_utils import query_to_list from ..utils.metadata_utils import deserialize_metadata, serialize_metadata -from ..utils.string_utils import build_lancedb_filter_expression -from ..utils.user_permissions import UserPermissions from .chunk_strategies import ( apply_fixed_size_strategy, apply_markdown_strategy, @@ -40,11 +35,6 @@ logger = logging.getLogger(__name__) -def get_connection_from_env() -> Any: -

index management abstraction and cleanup - Extend VectorIndexStore contract with index management methods (should_reindex, trigger_reindex with sync/async variants) - Implement index management in LanceDBVectorIndexStore - Add comprehensive index management tests (7 tests) - Remove duplicate index functions from vector_manager.py (_should_reindex, _trigger_reindex now use storage layer) - Update tests to use new StorageFactory API -

Changes: 1. PromptTemplateStore contract (contracts.py): - Add update_metadata() - Update metadata only, keep same version/ID - Add delete_by_name() - Delete by name with is_latest management - Add get_versions_by_name() - Get all versions of a template - Add async variants for all new methods 2. LanceDBPromptTemplateStore implementation (lancedb_stores.py): - Implement update_metadata() with in-place metadata update - Implement delete_by_name() with is_latest flag management - Implement get_versions_by_name() for version listing - Fix delete_prompt_template() to update is_latest for remaining versions - Add async variants delegating to sync methods 3. prompt_manager.py refactoring: - update_prompt_template() uses update_metadata() for metadata-only updates - delete_prompt_template() uses delete_by_name() and delete_prompt_template() - list_prompt_templates() uses store abstraction directly - Remove unused imports (escape_lancedb_string, pandas) - Remove unused _deserialize_metadata() function 4. main_pointer_manager.py refactoring: - All functions use MainPointerStore abstraction - Remove get_connection_from_env() function - Remove _build_base_filter_expression() function - Remove ensure_main_pointers_table import - Remove dependencies on escape_lancedb_string and build_lancedb_filter_expression 5. Test updates: - Fix mock objects in test_lancedb_stores.py for new methods - Rewrite test_main_pointer_manager.py to use new abstraction layer - All 78 tests passing (44 prompt_manager + 25 storage + 9 main_pointer_manager) This completes Phase 2.4 requirements: - PromptTemplateStore extended to support complete business logic - MainPointerStore extended to support complete business logic - Manager layers fully refactored to use storage abstractions - No direct get_connection_from_env() usage in business logic - All tests passing --- .../prompt_manager/prompt_manager.py | 393 ++++-------- .../tools/core/RAG_tools/storage/contracts.py | 86 +++ .../core/RAG_tools/storage/lancedb_stores.py | 171 +++++- .../main_pointer_manager.py | 221 ++----- .../RAG_tools/storage/test_lancedb_stores.py | 12 + .../test_main_pointer_manager.py | 580 +++++++----------- 6 files changed, 648 insertions(+), 815 deletions(-) diff --git a/src/xagent/core/tools/core/RAG_tools/prompt_manager/prompt_manager.py b/src/xagent/core/tools/core/RAG_tools/prompt_manager/prompt_manager.py index e6b7dd8f4..840df4ef8 100644 --- a/src/xagent/core/tools/core/RAG_tools/prompt_manager/prompt_manager.py +++ b/src/xagent/core/tools/core/RAG_tools/prompt_manager/prompt_manager.py @@ -2,6 +2,9 @@ This module provides functions for managing prompt templates with full CRUD operations and transparent version management using LanceDB. + +Phase 1A Part 2: Refactored to use PromptTemplateStore abstraction layer +for basic operations while preserving complex business logic.

Changes: 1. Import fixes: - Add missing IndexPolicy import in lancedb_stores.py - Remove unused imports (cast, IndexPolicy, build_filter_from_dict, datetime) - Remove unused variables (model_tag_arg, custom_policy) 2. Type safety fixes: - Add type assertions for name parameter in prompt_manager.py - Fix FilterExpression type invariants (use tuple instead of list) - Add type: ignore comments for lancedb.connect_async - Add cast() for pandas.to_dict("records") return type 3. Code cleanup: - Remove NULL model_tag fix-up logic in LanceDBMainPointerStore.set_main_pointer() - Remove duplicate test function (test_write_vectors_reindex_policy_configuration) - Remove _build_base_filter() call (no longer needed) 4. Formatting: - Apply ruff-format auto-formatting to all files All Python linters now pass: - ruff check: Passed - ruff format: Passed - mypy: Passed - isort: Passed - codespell: Passed Note: npm type-check fails due to frontend issues unrelated to this work.

Apr 2026 11:14:48 +0800 Subject: [PATCH 15/21] fix(storage): resolve remaining PR #158 review comments and test failures This commit addresses the remaining unresolved review comments from PR #158 and fixes associated test failures. All critical and major issues are now resolved. - **Comment #2**: Fix inconsistent model field write vs read - Unify write and read paths to use `embedding_config.id` as single source of truth - Eliminates duplicate embeddings caused by model ID mismatch - **Comment #3**: Fix user_id=None losing configs in admin mode - Admin mode (is_admin=True, user_id=None) now keeps uid=None - Enables admin workflows to load all collection configs correctly - **Comment #4**: Implement thread isolation for async execution - Add `_run_in_separate_loop()` to handle async in sync contexts - Prevents "event loop already running" errors in FastAPI handlers - Automatically detects execution context and chooses appropriate strategy - **Comment #6**: Remove auto-migration during read operations - Eliminate `while True` migration loop in `_open_embeddings_table()` - Use legacy fallback only; explicit migration via `migrate_embeddings_table()` - Prevents inline migration without locks or concurrency protection - **Comment #7**: Unify error handling between search_engine and search_sparse - Update `search_sparse.py` to re-raise primary_exc like `search_engine.py` - Ensures consistent error messages for "table not found" scenarios - **Comment #8**: Add structured logging for Hub resolution failures - Replace silent exception swallowing with structured logging - Log error_type, error_message, fallback_behavior, and impact - Applies to both `collection_manager.py` and `migration_utils.py` - **Comment #13**: Fix mock tests to use real storage layer - Update test patches from `get_connection_from_env` to correct paths - Tests now use real storage implementations via `conftest.py` fixtures - Add `temp_lancedb_dir`, `real_store`, `manager_with_real_store` fixtures - 800+ tests passing (up from 757 before fixes) - All mock path issues resolved - Remaining 10 test failures are due to `owners` field (known issue from later development) **Core Implementation:** - `collection_manager.py`: Add `_run_in_separate_loop()` and structured logging - `collections.py`: Fix user_id=None handling for admin mode - `document_ingestion.py`: Unify model field usage - `search_sparse.py`: Match error handling with `search_engine.py` - `migration_utils.py`: Add structured logging - `vector_manager.py`: Remove auto-migration code **Test Files:** - Multiple test files updated for correct mock paths - Add `management/conftest.py` for real storage fixtures - Update 30+ test files to use `get_vector_store_raw_connection` **Storage Layer:** - `lancedb_stores.py`: Maintain `get_connection_from_env` to avoid circular imports - Test patches updated to target correct module paths --- .../management/collection_manager.py | 17 +- .../core/RAG_tools/management/collections.py | 16 +- .../RAG_tools/pipelines/document_ingestion.py | 6 +- .../core/RAG_tools/retrieval/search_dense.py | 6 +- .../core/RAG_tools/retrieval/search_engine.py | 7 +- .../core/RAG_tools/retrieval/search_sparse.py | 8 +- .../tools/core/RAG_tools/storage/contracts.py | 46 ++- .../core/RAG_tools/storage/lancedb_stores.py | 36 +- .../core/RAG_tools/utils/migration_utils.py | 353 +++++++++++++++++- .../vector_storage/vector_manager.py | 114 ++---- .../version_management/cascade_cleaner.py | 4 +- .../version_management/list_candidates.py | 4 +- src/xagent/core/tools/core/document_search.py | 4 +- src/xagent/web/api/kb.py | 2 +- .../RAG_tools/LanceDB/test_schema_manager.py | 4 +- .../LanceDB/test_schema_migration.py | 28 +- .../RAG_tools/chunk/test_chunk_document.py | 60 ++- .../core/RAG_tools/management/conftest.py | 123 ++++++ .../management/test_collection_manager.py | 178 +++++---- .../RAG_tools/management/test_collections.py | 29 +- .../pipelines/test_document_search.py | 8 +- .../RAG_tools/retrieval/test_search_dense.py | 36 +- .../RAG_tools/retrieval/test_search_sparse.py | 18 +- .../RAG_tools/test_metadata_propagation.py | 26 +- .../tools/core/RAG_tools/test_multitenancy.py | 45 ++- .../RAG_tools/utils/test_migration_utils.py | 6 +- .../test_embeddings_forward_migration.py | 41 +- .../vector_storage/test_index_manager.py | 8 +- .../vector_storage/test_vector_manager.py | 31 +- .../test_cascade_cleaner.py | 20 +- .../test_list_candidates.py | 14 +- .../test_rag_refactored_integration.py | 8 +- 32 files changed, 922 insertions(+), 384 deletions(-) create mode 100644 tests/core/tools/core/RAG_tools/management/conftest.py diff --git a/src/xagent/core/tools/core/RAG_tools/management/collection_manager.py b/src/xagent/core/tools/core/RAG_tools/management/collection_manager.py index 36f209d08..2f77bfedb 100644 --- a/src/xagent/core/tools/core/RAG_tools/management/collection_manager.py +++ b/src/xagent/core/tools/core/RAG_tools/management/collection_manager.py @@ -557,20 +557,18 @@ def resolve_effective_embedding_model_sync( raise -def rebuild_collection_metadata() -> None: +async def rebuild_collection_metadata() -> None: """Rebuild collection_metadata table from existing data.

Finding 1: Fix async FTS detection logic to match sync version - Finding 2: Replace fragile string parsing with structured IndexResult **Problem:** `search_sparse_async` incorrectly assumed FTS is enabled when `create_index()` succeeds, but it may only create vector index, not FTS. **Solution:** - Add `fts_enabled` field to IndexResult dataclass - Update `create_index()` to return IndexResult with actual FTS status - Check actual FTS index status using `table.list_indices()` - Update async version to use `index_result_obj.fts_enabled` like sync version **Problem:** `create_index()` returned ad-hoc string format `"status advice: message"` parsed via fragile string split. **Solution:** - Create IndexResult Pydantic model in core/schemas.py - Update VectorIndexStore.create_index() contract to return IndexResult - Add fields: status, advice, fts_enabled - Update all call sites to use structured field access - Remove redundant `get_vector_index_store()` calls (Finding 4) - Fix `get_raw_connection()` caching inconsistency (Finding 5) - All search_sparse tests passing (10/10) - All search_dense tests passing - Tests now use IndexResult objects instead of string mocks **Core Implementation:** - `core/schemas.py`: Add IndexResult Pydantic model - `storage/contracts.py`: Update create_index contract, add IndexResult import - `retrieval/search_engine.py`: Use IndexResult, remove redundant call - `retrieval/search_sparse.py`: Use IndexResult, fix async FTS detection - `storage/lancedb_stores.py`: Return IndexResult, check actual FTS status, fix caching **Test Files:** - Update all mock `create_index.return_value` to return IndexResult - Add IndexResult imports to test files --- .../core/tools/core/RAG_tools/core/schemas.py | 23 +++++++ .../core/RAG_tools/retrieval/search_engine.py | 17 ++--- .../core/RAG_tools/retrieval/search_sparse.py | 23 ++----- .../tools/core/RAG_tools/storage/contracts.py | 6 +- .../core/RAG_tools/storage/lancedb_stores.py | 69 +++++++++++++------ .../RAG_tools/retrieval/test_search_dense.py | 31 +++++++-- .../RAG_tools/retrieval/test_search_sparse.py | 64 ++++++++++++++--- 7 files changed, 166 insertions(+), 67 deletions(-) diff --git a/src/xagent/core/tools/core/RAG_tools/core/schemas.py b/src/xagent/core/tools/core/RAG_tools/core/schemas.py index ea808057d..7c0b6cf4c 100644 --- a/src/xagent/core/tools/core/RAG_tools/core/schemas.py +++ b/src/xagent/core/tools/core/RAG_tools/core/schemas.py @@ -799,6 +799,29 @@ class HybridSearchResponse(BaseModel): ) +class IndexResult(BaseModel): + """Structured result from index creation operations. + + This model replaces the previous string-based return format for create_index, + providing type-safe access to index status, advice, and FTS enabled state. + + Attributes: + status: Index creation status (e.g., "index_ready", "readonly", "failed") + advice: Optional advice message for further actions + fts_enabled: Whether FTS index is actually enabled (separate from vector index) + """ + + model_config = ConfigDict(frozen=True) + + status: str = Field(..., description="Index creation status") + advice: Optional[str] = Field( + default=None, description="Human-readable index advice" + ) + fts_enabled: bool = Field( + default=False, description="Whether FTS index is enabled on text column" + ) + + class SearchConfig(BaseModel): """Configuration for the unified document search pipeline.""" diff --git a/src/xagent/core/tools/core/RAG_tools/retrieval/search_engine.py b/src/xagent/core/tools/core/RAG_tools/retrieval/search_engine.py index e36cdaf73..d3245e241 100644 --- a/src/xagent/core/tools/core/RAG_tools/retrieval/search_engine.py +++ b/src/xagent/core/tools/core/RAG_tools/retrieval/search_engine.py @@ -10,7 +10,7 @@ import logging from typing import Any, Dict, List, Optional, Tuple -from ..core.schemas import SearchResult +from ..core.schemas import IndexResult, SearchResult from ..LanceDB.model_tag_utils import to_model_tag from ..storage.contracts import FilterExpression from ..storage.factory import get_vector_index_store, get_vector_store_raw_connection @@ -82,15 +82,9 @@ def search_dense_engine( # Check and create index if needed (using storage abstraction) vector_store = get_vector_index_store() -

Added convenience methods to VectorIndexStore contract: - search_vectors_by_model(): sync vector search by model_tag - search_vectors_by_model_async(): async vector search by model_tag - search_fts_by_model_async(): async FTS search by model_tag These methods internally combine open_embeddings_table() with the respective search operations, providing a simpler one-step API for the most common use case of searching by model_tag. 2. Updated retrieval layer to use new convenience methods: - search_dense_engine (sync/async): now uses search_vectors_by_model - search_sparse_async: now uses search_fts_by_model_async This eliminates the previous two-step pattern of opening the table first then passing the table_name to search functions. 3. Removed legacy IndexManager code: - Deleted vector_storage/index_manager.py (254 lines) - Removed _open_embeddings_table, validate_embed_model, and get_stored_vector_dimension functions from vector_manager.py - Updated vector_storage/__init__.py exports - Removed corresponding tests (test_index_manager.py and related tests) 4. Legacy fallback logic now centralized: - All table opening and legacy fallback logic is now handled by VectorIndexStore.open_embeddings_table() - This provides a single source of truth for table name resolution - Both sync and async code paths benefit from unified implementation 5. Simplified validation: - validate_query_vector no longer requires database connection - Dimension validation is now handled by the storage abstraction layer - Removed conn parameter and DB-dependent validation logic Changes: - storage/contracts.py: Added 3 convenience methods with default implementations - storage/lancedb_stores.py: Added open_embeddings_table() implementation - retrieval/search_engine.py: Updated to use search_vectors_by_model - retrieval/search_sparse.py: Updated to use convenience methods - retrieval/search_dense.py: Removed raw connection usage for validation - vector_storage/*: Removed legacy IndexManager and related functions - tests/*: Updated tests to use new abstraction layer, removed deleted function tests Net changes: +439, -1515 lines across 19 files --- .../core/RAG_tools/retrieval/search_dense.py | 30 +- .../core/RAG_tools/retrieval/search_engine.py | 91 +-- .../core/RAG_tools/retrieval/search_sparse.py | 64 +- .../tools/core/RAG_tools/storage/contracts.py | 180 +++++ .../core/RAG_tools/storage/lancedb_stores.py | 138 +++- .../core/RAG_tools/vector_storage/__init__.py | 7 +- .../RAG_tools/vector_storage/index_manager.py | 254 ------ .../vector_storage/vector_manager.py | 201 +---- .../RAG_tools/chunk/test_chunk_document.py | 6 +- .../core/RAG_tools/core/test_factory_utils.py | 3 +- .../core/RAG_tools/management/conftest.py | 1 -

**Problem**: search_sparse was pre-transforming model_tag with "embeddings_" prefix, then open_embeddings_table would add it again, causing "embeddings_embeddings_model" table name errors. - **Fix**: Removed pre-transformation in search_sparse; open_embeddings_table now handles all prefix logic internally. - **Impact**: Sparse search now correctly resolves table names for both Hub ID and legacy provider-based naming. - **Problem**: create_index() in readonly mode returned fts_enabled=False without checking if FTS index already existed. - **Fix**: In readonly mode, open table and check existing FTS index status before returning IndexResult. - **Impact**: Readonly queries can now correctly detect and use existing FTS indexes, improving test coverage and production query accuracy. - Updated test mocks to use search_vectors_by_model() instead of raw connection pattern. - Removed build_filter_expression assertions (now called inside abstraction layer). - Fixed validate_query_vector call expectations (no longer passes model_tag parameter). - Added `import unittest` for unittest.mock.ANY usage. - Updated tests to patch get_vector_index_store instead of get_vector_store_raw_connection. - Fixed open_embeddings_table return value expectations (now returns tuple (table, table_name)). - Updated model_tag assertions to expect untransformed values (abstraction layer handles prefix). - Fixed test_search_sparse_database_error to patch resolve_embedding_adapter in correct location (utils.model_resolver). - Updated all create_index mock returns to return IndexResult objects instead of strings. - Fixed test_write_vectors_index_status_aggregation to use IndexResult objects in side_effect. - test_search_dense.py: 13 passed -

Exception Handling Consistency: - Add try-except block to search_dense (Sync) to return structured error responses - All four search entry points now have unified exception handling pattern: * search_dense (Sync) - now returns DenseSearchResponse with status="failed" * search_dense_async (Async) - already had exception handling * search_sparse (Sync) - already had exception handling * search_sparse_async (Async) - already had exception handling 2. Test Mock Level Improvements: - Replace mock-based tests with real storage tests in TestSyncFunctions - Add integration test for rebuild_collection_metadata - Update multitenancy tests to use CollectionManager instead of non-existent register_collection - All tests now verify complete data flow through storage layer 3.
