* **Immediately rectify abysmal security score; high volume of critical issues is alarming.** Zero security score necessitates urgent review of dependencies and configuration hardening. * **Eliminate redundant login routes in `server.js` for better structural integrity and maintenance.** Consolidate all authentication logic within the dedicated `backend/routes/auth.js` module. * **Refactor `Data` model's 16 generic parameters to specific, descriptive sensor fields.** Ambiguous modeling using `param1` through `param16` severely limits domain context and querying usefulness. * **Secure authentication utilizes standard bcrypt hashing and JWT, a robust architectural foundation.** Proper use of salted hashing and environmental variables for secrets demonstrates solid security fundamentals. * **Improve frontend API abstraction by parameterizing hardcoded limits like `limit=10`.** The `api.js` service layer should handle dynamic request parameters efficiently, not brittle hardcoded limits.
