# Decision Ledger Coverage — Definition of Success

> KPI: Decision Ledger Coverage
> Target: 100% of AI actions with backfilled outcome

**What this number means:** every AI decision (confidence-gated policy
engine outcome) is captured in the Decision Ledger with its outcome
backfilled from the subsequent apply.completed/failed event.

**How it's computed:** `count(decision_ledger rows WHERE outcome ≠
'pending') ÷ count(decision_ledger rows)`. Sourced from
`metrics/decision_ledger.db`.

**What "good" looks like:** 100% means no AI decision is ever lost or
left without an outcome. The ledger is the trust substrate (NORTH_STAR
Objective #2).
