Plan 08-05 Summary — Documents API Decomposition

Status: Complete
Requirements: CODE-02, CODE-08
Date: 2026-06-12

What Was Done

• Created backend/api/documents/ package: shared.py, upload.py, crud.py, content.py, __init__.py
• __init__.py aggregates with prefix="/api/documents" — 9 routes total
• _CLOUD_PROVIDERS, UploadUrlRequest, DocumentPatch defined once in shared.py (CODE-08)
• list_documents registered directly on parent router (FastAPI 0.128 empty-path/prefix restriction)
• get_storage_backend_for_document re-exported in __init__.py for test monkeypatching compatibility
• Deleted backend/api/documents.py monolith after 43-test regression passed

Test Results

• tests/test_documents.py: 39 passed, 4 xfailed
• tests/test_shares.py: 4 passed
• Full suite: 405 passed
