From 3108fe1dffca1c819b9af1229f9648eef198ae49 Mon Sep 17 00:00:00 2001 From: beabigegg Date: Mon, 29 Dec 2025 22:03:05 +0800 Subject: [PATCH] feat: implement document management module MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Backend (FastAPI): - Attachment and AttachmentVersion models with migration - FileStorageService with SHA-256 checksum validation - File type validation (whitelist/blacklist) - Full CRUD API with version control support - Audit trail integration for upload/download/delete - Configurable upload directory and file size limit - Frontend (React + Vite): - AttachmentUpload component with drag & drop - AttachmentList component with download/delete - TaskAttachments combined component - Attachments service for API calls - Testing: - 12 tests for storage service and API endpoints - OpenSpec: - add-document-management change archived 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude
