Enable RLS on all remaining tenant-scoped tables (31 tables): Standard policy (tenant sees own rows): users, account_invites, account_limit_overrides, account_feature_overrides, subscriptions, ai_chat_sessions, ai_conversations, ai_session_steps, ai_session_embeddings, ai_suggestions, ai_usage, assistant_chats, attachments, copilot_conversations, feedback, file_uploads, fork_points, kb_imports, notifications, notification_configs, notification_logs, psa_activity_logs, psa_member_mappings, script_builder_sessions, script_categories, session_ratings, tree_embeddings, user_folders, user_pinned_trees Platform-visibility policy (own rows OR PLATFORM_ACCOUNT_ID): platform_steps, template_trees Intentionally skipped: accounts (IS the root table, no account_id column) plan_feature_defaults (platform config, no account_id column) Also fixes script_builder_service.create_session() which was missing account_id= on ScriptBuilderSession construction, causing 500s on all script builder endpoints (pre-existing CI failure). Adds Phase 4 RLS isolation tests covering: users, script_builder_sessions, ai_session_steps, notifications, platform_steps, template_trees. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Troubleshooting Decision Tree - Backend API
FastAPI backend for the Troubleshooting Decision Tree application.
Quick Start
1. Set up Python environment
cd backend
python -m venv venv
# Windows
venv\Scripts\activate
# macOS/Linux
source venv/bin/activate
pip install -r requirements.txt
2. Start PostgreSQL database
Using Docker:
docker-compose up -d
Or install PostgreSQL locally and create a database:
CREATE DATABASE decision_tree;
3. Configure environment
Copy the example env file and update as needed:
cp .env.example .env
4. Run database migrations
alembic upgrade head
5. Start the server
uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
The API will be available at:
- API: http://localhost:8000
- Docs: http://localhost:8000/api/docs
- ReDoc: http://localhost:8000/api/redoc
