SLI and SLO Reference

Core SLIs

• write queue-wait p99
• quorum-ack p99
• write success/error rates
• lease lane service stability
• profile switch rate and oscillation behavior

SLO Framing Guidance

• Define lane-specific objectives (Tier-0 vs normal).
• Separate correctness gates from performance gates.
• Use run-ID-backed benchmark evidence for any public claim.
