**21. Test fixtures in `conftest.py`:** Available fixtures are `client` (async HTTP client), `test_db` (async session), `test_user` (registers user, returns email/password/user_data), `auth_headers` (Bearer token dict), `test_tree` (creates a tree), `test_admin` (super_admin user), `admin_auth_headers` (admin Bearer token). There is NO `async_client` or `engineer_token` fixture.
**23. Action nodes navigate via `next_node_id`, not `children`:** `TreeNavigationPage.tsx` handles action nodes by following `next_node_id` only — the `children` array on action nodes is ignored at runtime. Action nodes without `next_node_id` render no "Continue" button (dead end). Any AI generation or manual tree editing must set `next_node_id` on action nodes.
**24. Anthropic model IDs require full dated version string:** `claude-haiku-4-5` is invalid; must be `claude-haiku-4-5-20251001`. See `backend/app/core/config.py``AI_MODEL`.
**25. Claude API may wrap JSON responses in markdown fences:** When parsing AI-generated JSON, always strip ` ```json ... ``` ` fences before parsing. See `_strip_markdown_fences()` in `ai_tree_generator_service.py`.
