Per post_module_taxonomy_de_cruft_20260627 Phase 2 (FR7 continued).
The previous migration commit (8f11340b) handled the
'from src.models import X' pattern (85 sites). This commit handles
the 'models.<moved_class>' attribute access pattern (44 sites in 20
files), which the __getattr__ shim previously supported.
The migration was performed by the one-time script
scripts/tier2/artifacts/post_module_taxonomy_de_cruft_20260627/migrate_models_attr.py
which:
1. For each 'models.<moved_class>' reference, replaces it with the
bare class name (e.g., 'models.MCPConfiguration' -> 'MCPConfiguration')
2. Adds the import 'from src.<destination> import <moved_class>' at
the top of the file (deduplicated if the import already exists)
3. Skips moved classes that the file already imports directly
The migration script inserts the import after the 'from __future__
import annotations' line if present; otherwise it adds the import
to the destination module's existing import block. Two files
required manual fixes because the script's regex didn't handle them:
- src/rag_engine.py: uses 'from src import models' (not 'from
src.models import X'); the class is accessed
via 'models.RAGConfig'. Replaced with a
direct 'from src.mcp_client import RAGConfig'
import and removed the 'from src import models'.
- tests/test_project_context_20260627.py: uses the parens-style
multi-line 'from src.models import (X, Y, Z)'.
Replaced with the parens-style direct import.
After this commit:
- 'models.MCPConfiguration', 'models.FileItem', 'models.Ticket', etc.
no longer work in src/ and tests/ (the AttributeError raises
because models.py no longer has the __getattr__ entries for
moved classes)
- All consumer files have direct imports of the moved classes
Total: 44 'models.<moved_class>' references rewritten across 20 files.
The fix in 644d88ab changed the recovery path from client.delete_collection
to shutil.rmtree (chromadb 1.5.x delete_collection is broken on corrupted
state). The test still asserted the old behavior.
- Corrected GeminiEmbeddingProvider model name to gemini-embedding-001.
- Prevented _fetch_models from overwriting active i_status (sending/done/error).
- Updated est_rag_engine.py to correctly patch the lazy-loaded chromadb getter.
- Adjusted RAG simulation tests to account for the new initializing... status and automatic initial indexing.
- Fixed typo in est_z_negative_flows.py.
