RS Level

Runtime Stability Level — A capability maturity model for runtime protection.

RS Level is a formal evaluation metric defined in the Runtime Stability Framework v3.3. It measures the structural maturity of a system's runtime protection — not its feature count, not its vendor certifications.

The formula
RS = SL + IL
SL (Security Level): 0–3, based on detection capability — Recall, Precision, Response Latency.
IL (Immunity Level): 0–3, based on structural outcome nullification capability.
RS: 0–6 (ordinal scale)

RS Level is not a scoring system. It represents the degree of progression toward Runtime Stability.

NoticeRS is an ordinal scale. Multiple SL/IL combinations can yield the same RS value. The appropriate target RS level depends on domain requirements, not maximum optimization.

Levels

The progression from RS-0 to RS-6 represents a qualitative shift in the structural character of protection: from visibility, to controllability, to outcome nullification, toward integrated Runtime Stability.

RS-0
No runtime protection. Perimeter defense only.
SL-0, IL-0
Internal tools with no external exposure.
RS-1
Basic detection capability. Single-layer monitoring.
SL-1 or IL-1
Low-risk internal systems.
RS-2
Multi-layer detection. Coordinated response capability.
SL-2 or equivalent combination
Standard enterprise SaaS, online services.
RS-3
Detection with partial immunity. Blast radius begins to shrink.
SL-2 + IL-1 or equivalent
SaaS platforms, online trading systems.
RS-4
Coordinated detection and structural immunity. Significant outcome nullification.
SL-2 + IL-2 or equivalent
Financial institutions, healthcare systems.
RS-5
Advanced immunity. Detection gaps structurally compensated.
SL-3 + IL-2 or equivalent
Autonomous vehicles, defense supply chain.
RS-6
Full Runtime Stability. Practical nullification achieved. Attacker ROI structurally negative.
SL-3 + IL-3
Defense-related systems, critical infrastructure, systems where halting equals failure.

NoticeRS-6 is the strongest practical defense under current cryptographic assumptions. It does not represent absolute protection — it represents structural infeasibility of exploitation.
