Deep Modularization, Reliability Engineering, and Admin Tools
A cleaner architecture, smarter error recovery, and controlled early access — Arivu's foundation for what comes next.
Our earlier hardening pass laid the groundwork — security, speed, and an initial split into smaller modules. This update goes deeper. We’ve broken the backend into fully independent domains, added retry and conflict handling for reliability, built a testing infrastructure that catches problems before you see them, and shipped an admin dashboard for controlled early access.
Full Domain Separation
The initial hardening split out a few core services. This time, we went further — every major feature area now lives in its own domain with clear boundaries. Authentication has its own dedicated layer, including lockout and email handling. Bookmarks, collections, analytics, import/export, knowledge graph, search, and AI processing are all independent.
A shared data model layer ensures consistency across all of these domains without tight coupling.
What this means for you: When we ship a new feature in one area, it can’t accidentally break something in another. Updates land faster, and bugs stay contained.
Smarter Error Recovery
AI-powered features like summaries and auto-tagging now have automatic retry logic. If an AI call fails — network hiccup, temporary service issue — Arivu retries intelligently instead of silently dropping your result.
We also added conflict handling for concurrent edits. If you update a bookmark from two tabs or devices at the same time, Arivu detects the conflict and resolves it cleanly instead of letting one edit silently overwrite the other.
Protection against abuse is now layered across the application, not just on login.
What this means for you: Fewer “something went wrong” moments. Your AI summaries arrive reliably, your edits don’t get lost, and the app stays responsive under load.
Testing That Catches Problems Early
We built a testing infrastructure that goes well beyond basic checks. Concurrent operation tests verify that multiple users editing simultaneously don’t corrupt data. A load testing framework simulates real-world traffic patterns so we can find bottlenecks before you hit them. A database migration framework ensures safe schema changes as Arivu evolves.
The authentication system alone now has over 700 lines of dedicated tests covering edge cases.
What this means for you: More confidence that things work correctly. The kind of subtle bugs that only appear under real usage conditions — race conditions, data conflicts, slow queries at scale — get caught in testing, not in your workflow.
Admin Dashboard & Invite System
Arivu now has an admin dashboard for monitoring system health and managing early access. New users join through an invite system, which lets us onboard people in a controlled way and ensure everyone gets a stable experience.
What this means for you: If you’re using Arivu during early access, you’re in a curated group. We can monitor quality closely and respond quickly to issues.
This is foundation work — the kind that doesn’t show up as a flashy new feature but makes every future feature possible. A modular codebase, reliable error handling, real testing infrastructure, and controlled onboarding. The next set of features ships on top of this.
