# Attestation Coverage — Definition of Success

> KPI: Attestation Coverage
> Target: 100% of prod/dr promotions attested by a human

**What this number means:** every production and disaster-recovery
promotion has a recorded human attestation (approver identity, 8-concern
matrix result, separation-of-duties check on prod). This is the
"autonomy in operations, human in accountability" proof.

**How it's computed:** `count(prod/dr promotions with attestation.recorded
event) ÷ count(total prod/dr promotions)`. Sourced from the Decision
Ledger (`attestation.recorded` events) + `hitl_gates.py` + outbox
`approver_*` attributes.

**What "good" looks like:** 100% means no prod/dr promotion ever lands
without a human sign-off on record. The absence of an operator is never
the absence of a record (NORTH_STAR Anti-Goal #3).
