RuVector Postgres v2 - Self-Healing System
The Missing Piece
We built the sensor (mincut integrity monitoring). Now we build the actuator (automated remediation).
Most systems detect problems and alert humans. We detect problems and fix them automatically.
Traditional: Detect → Alert → Human → Diagnose → Fix → Verify
Self-Healing: Detect → Classify → Remediate → Verify → Learn
This completes the control loop and makes RuVector truly autonomous.
Design Principles
- Graduated response — Small problems get small fixes
- Reversible actions — Every remediation can be undone
- Blast radius limits — Never make things worse
- Audit trail — Every action is logged and signed
- Learn from outcomes — Improve remediation over time

Problem Classification
Witness Edge Analysis
The mincut computation produces witness edges — the edges that would break the graph. These reveal the problem type.

(automatic recovery)
This is what makes RuVector truly different:
We don't just detect problems early. We fix them automatically before they become incidents.
The system is not just observable. It is self-aware and self-repairing.
