# Human Escalation Frequency — Definition of Success

> KPI: Human Escalation Frequency
> Target: < 0.1% of platform actions (Post-Pilot)

**What this number means:** how often the AI platform was forced to fall
back or escalate to a human operator due to low confidence. This is the
inverse of Touchless Resolution Rate, scoped to operational escalations
only.

**How it's computed:** `count(runs WHERE hitl_block = 1 AND reason =
'confidence')` ÷ `total runs`. Attestation sign-offs are excluded.

**What "good" looks like:** < 0.1% means fewer than 1 in 1000 runs
require human intervention. Near-zero is the goal.

**What would be "gamer metrics":** counting attestation sign-offs as
escalations (they're not — they're designed controls).
