What it may solve
Authentication gate for the DeepSeek Harness Web UI: login covers pages, /api, /plugins and WebSocket upgrades; PBKDF2 password hashing, HttpOnly SameSite session cookies, IP-based login lockout, a user-management settings panel (users edit their own profile, admins add or remove users and reset passwords), admin-only model and API-key configuration guards, per-user isolation on the REST/list APIs and the WebSocket event streams, session persistence across restarts, a JSONL audit log, and a fail-closed gateway.
