# 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
