## Issue a delegation

TypeScript:

```
const delegation = await kye.delegations.create({
  actor:     "kye:agent:acme.kyc_triage_001",
  principal: "kye:user:acme.compliance_lead",
  subject:   "kye:business:retail_customer_segment",
  scope:     ["kyc.verify", "kyc.read"],
  expires_at:"2026-12-31T00:00:00Z"
});
```

Python:

```
delegation = kye.delegations.create(
    actor="kye:agent:acme.kyc_triage_001",
    principal="kye:user:acme.compliance_lead",
    subject="kye:business:retail_customer_segment",
    scope=["kyc.verify", "kyc.read"],
    expires_at="2026-12-31T00:00:00Z",
)
```

## Get a decision

```
const d = await kye.decisions.create({
  actor: "kye:agent:acme.kyc_triage_001",
  principal: "kye:user:acme.compliance_lead",
  capability: "kyc.verify",
  context: { customer_id: "cust_001", region: "EU" }
});
if (d.decision === "allow") { /* proceed */ }
else if (d.decision === "require_human_review") { /* queue */ }
```

  https://api.kyeprotocol.com/v1/evidence-packs/kye:evidence-pack:adoption_acme_q1_2026 \
