## Knowledge Gaps
- **5 isolated node(s):** `FastAPI application factory.`, `JWT creation / verification and password hashing.`, `Generate business codes like BYJ20260424001 / BX20260424001.`, `Generate a sequential code: {prefix}{YYYYMMDD}{3-digit-sequence}.     prefix exa`, `MinioService`
  These have ≤1 connection - possible missing edges or undocumented components.
- **Thin community `Community 10`** (9 nodes): `role.py`, `assign_menus()`, `assign_users()`, `create()`, `get_by_id()`, `get_paged()`, `get_users_by_role()`, `soft_delete()`, `update()`
  Too small to be a meaningful cluster - may be noise or needs more connections extracted.
- **Thin community `Community 16`** (3 nodes): `BizError`, `.constructor()`, `client.ts`
  Too small to be a meaningful cluster - may be noise or needs more connections extracted.
- **Thin community `Community 18`** (3 nodes): `create_app()`, `FastAPI application factory.`, `main.py`
  Too small to be a meaningful cluster - may be noise or needs more connections extracted.
